How does the library function call Labview? Can I emulate using C++?

Hi all. I recently finished writing a dll CUDA for LabView, and now I'm in the steps of optimization of code, memory management, etc. BUT since my code depends on the entries of Labview (lots of data under types of specific data as table manages and Clusters labview) I can't use the CUDA Profiler or the Profiler VC ++ on the DLL. What I intend to do runs labview and then out of all data entry for the DLL in a binary file and then add an additional function in my code that will read in the binary file, allocate and assign variables to their respective positions, and then call the specific DLL function in Labview. In the end, this miniature function will act as the library function call to my specific group of data entries.

In any case, I started to make this purchase all my data entry of cluster and it comes out in a binary file. And then I started the initialization of the handles of labview, allocating memory and begins to write the binary data in the memory and it works for integers (ints), floats, etc., but I'm confused on how it works with table handles!

Some examples of code:

Sets the Handle for table 1 d for INT
typedef struct {}
int length;
int val [1];
to access the value in a row-online val [Online]
} Array1dInt, * Array1dIntHandle;

int main()
{
Array1dIntHandle x = new Array1dInt *;
(* x) = new Array1dInt;

ifstream file ('TESTDATAIN.dat', ios: in | ios::binary);

If (file.is_open ())
{
file ((char *) &(*x)-> length, sizeof;)
file ((char *) &(*x)-> val [0], sizeof (int) *(*x)-> length);

LabviewSpecificFunction (x);
leader. Close();
} else
{
< "file="" did="" not="" open!"=""><>
}
return 0;
}

__declspec(dllexport) LabviewSpecificFunction (Array1dIntHandle x)
{
...
}

However, my program crashes when the table is nominally big, and it is expected, because if we look at the Array1dHandle, it has allocated only enough memory to 1 item of value! YET, somehow, in its magical and mysterious labview is capable of making val [1] be val [HOWEVERMANYYOUWANT], even if C++ 101 says that val [1] is a constant pointer, and even if I dynamically allocated memory another somwhere, I would never be able to put these data in this round!

Can you explain, or maybe even write example on how I can fool my program into thinking that the binary code comes from labview, so I can then run my program independent of allowing me to profile the functions inside labview?

I hope that this question is clear and my sample code is also clear, but I'm happy to answer any questions that relate to this.

Thank you all!

I think that I thought about it.

Array1dIntHandle x = new Array1dInt *;
int tempsize;
file ((char *) & tempsize, sizeof;)
(* x) = (Array1dInt *) malloc (sizeof (int) + sizeof (int) * tempsize);
(* x)-> length = tempsize;
file ((char *) &(*x)-> val [0], sizeof (int) *(*x)-> length);

Well enough, you will need to make the handle, and then make a new Array1dInt * for him, then read in the length of the array in a temporary variable. Then use this information to then malloc memoery quantity you need for the table and pass this place on the handle. Now the handle will point to the size of the memory and you will be able to access the memory in the format, you've done the handle. Badabing badaboom

    Can you tell me why sum function does not return to the same value?

    Kind regards

    As I expected wrong since this isn't a RAW number his tent for formatting. You can change this value and format or just go for the sum of RTF, or the SUM of your SQL query.

    Sum in RTF: for SUM_ACCOUNT_COST

    I have given how you use grouping in this case, based on what you might change the code slightly.

    I use the node of the library function call in LV 8.6. I checked the path to specify the box diagram and made directly in the DLL file that I use.

    Thank you

    Probably that DLL does not depend on other DLLs that reside in the same directory you point to in the configuration node dialog box call library. What is happening is this:

    Without going into this directory:

    LabVIEW applications Windows to load the DLL, Windows detects that it needs to load other DLLs and can not find in its standard search sites:

    (1) already loaded into memory

    (2) in the application directory (where the exe that began the current process resides in the LabVIEW IDE would be where is LabVIEW.exe)

    (3) in the system directory

    (4) in the Windows directory

    (5) any directory in the PATH environment variable contains

    (6) in the directory 'active '.

    Because Windows cannot find a person to load DLL he abandoned the main DLL loading and returns an error to LabVIEW.

    Now, you go to the configuration dialog box and point to the DLL. The dialog box browse file in LabVIEW uses the standard OS dialog box and this dialog box has the behavior obnoxious always update the "current" directory in the directory where a file got selected in. LabVIEW sees now that the path has "changed" and asks again to load the DLL. Yet once, Windows detects that it needs to load other DLLs too for this DLL but this time going over the search order, it will actually hit the DLL in the same directory and that's all fine.

    It is certainly NOT a problem of LabVIEW. LabVIEW does not and should not really need to know that a DLL needs other DLL loaded and more importantly should never try to think he can do better than Windows, it probably could, but is simply not his task of dependency DLL loading.

    It is your responsibility as a programmer and user of this DLL to know its dependencie, and if you did not write the DLL, to hit the original on his head programmer, if it has not documented these dependencies and make sure that these dependencies are actually properly resolved for Windows placing them in one of the places mentioned above

    ((2) is generally the best location for applications applications because it will not pollute the Windows directory or the user of the application system and 5) is the best for the development machine as you can add a directory to your PATH environment variable where you put the dll you need to develop a specific application.

    I try to call a fuction from a SDK.dll library by using the node call library feature. The SDK has been provided to

    The SdkSetPropertyEventHandler function has a function of recall as one of its parameters. How to apply the

    Yes, but I find the idea of using .net to call a LabVIEW VI as callback function C a bit as using a roll of Steam ironing your pants. Why do it? Well the steamroller has extra security guards that make it less likely that you'll break your pants in the process, but it's not elegant IMHO.

    Write a C DLL that translates between a C callback and a user event LabVIEW using the PostLVUserEvent() of the interface of the kernel to run LabVIEW function seems so eleganter for me. Yes, it's a bit of programming in C, but good!

  • Call the library function does not find the DLL in the directory where are my LLBs

    I'm using LabVIEW 8.6.  I have a set of screws in several LLBs.  All LLBs located in a directory.  Most of my screws is wrappers for the functions in a DLL.  I was told to put my DLL in the directory where are the LLBs, and apparently this is how the previous programmer has worked (using an earlier version of LabView).

    In the configuration of the library call, I've specified .dll without path.  (This is how we want our screws are an API that will integrate other programmers, so I don't know where they put things and I can't use absolute paths).

    When I insert the VIs in LabVIEW, LabVIEW can not find the DLL and wonder of spotted.  It's just that here in the directory with the LLBs and when I double click on it, everything works fine.  However my absolute path to the DLL now appears in the library to call configuration, and we don't want that.

    Does anyone know how to make this work?  I guess the location of the screw (or LLBs, in this case) should be the current directory and thus Windows search there for the DLL.  However, it seems that this is not the case (in the least, in the latest version of LabVIEW).

    Thank you.

    Well someone using your library should not have to dig into your screws and do it all on his own. Instead your library must wrap that and hide disorders it altogether.

    The cluster of error has been added when the dynamic path option has been added. It is not useful hide this error output, so it's always there. As well as the dynamic path, there was the improved error handling added the CLN. One of them is that the level of verification when calling function errors (exception handling) can be specified. I guess that some of these options may generate an error code instead of bring up a dialog box, as they did before and that the output of error code can be useful even in the case of static calls.

    As to what you want to do, I would have long managed that with a DLL that has essentially the same functions as your other wrapper DLLs and an initiliasation function that returns a pointer to a structure of functional distribution based on the actual DLL you want to call. Quite like what an object-oriented function dispatch table is. Then, when your interface initilising you call initialize function and specify the device interface/type that you want to use and after that all other functions take a pointer extra function parameter expedition as the first parameter, in addition to the parameters of the real function. This dispatch function pointer would be just a pointer to a structure that contains the table of function for this interface pointers and the sake of LabVIEW would simply be an integer of size pointer.

    The wrapper function then checks the pointer structure validity send feature and call the actual function with the remaining parameters. It is a C programming and may require a planning and desigining the different interfaces to facilitate this kind of technique of the expedition, but it will certainly pay to long-term and make your library even can be used in previous versions of LabVIEW, so that VB etc. without delicate dynamic loading in the level high, programming environment.

  • When I use the library function node call in real time, is loaded only once for all or load the DLL whenever it is called?

    When I use the library function node call in real time, is loaded only once for all or load the DLL every time when it is called?

    Thank you in advance.

    The user interface thread is the thread that is used to update the user interface. It's slow. And it's supposed to be that way because humans are slow.

    The call library function node can be configured as this thread to use in the configuration for it dialog box. Please visit the LabVIEW documentation on how to do this.

  • Make sure that wire you all the inputs and outputs of your node library function call?

    This document says "make sure that wire you all the inputs and outputs of your node library function call.

    http://digital.NI.com/public.nsf/WebSearch/7253D2F0D91F68058625752F005AB672?OpenDocument&submitted&&...

    But all the terminals on the right side of the call library node considered "outputs" referred to in the foregoing statement?

    This same document continues to show the right way to allocate memory with this illustration and in the illustration, the right "outputs" are left without junctions.

    Am I right in assuming that the only terminals that count as outputs, those who use the code of the DLL (modify) as output?  If it is true, then all other terminals output associated with the values entered alone so don't really account as outputs, correct?

    In the parameter call-library configuration screen there is a "Constant" check box and the help that he wrote "indicates whether the parameter is a constant."  What is this box? for me in the setup of the DLL call

    Finally, assuming that a call from the DLL that is supposed to write in these five outputs, is it legitimate to use constants like this to book a space of memory for the output values?

    How about if local variables associated with the output terminals are used instead?

    Despite the linked document, it is necessary to connect the corresponding entry for simple scalar output parameters (for example a digital). LabVIEW automatically allocate memory for them. If you do not want the entries for all the output wire anyway, there should not be no difference between a constant and a local variable; I would use a constant to avoid useless local variables.

    For settings that are only entries, there is not need to connect the outlet side. It's a bit simplistic since all parameters are entered only and get one result (other than the return value), you pass a memory address and modify the content to this address, but LabVIEW manages this dereferencing pointer for you. If you want to really get into the details, learn more about pointers in C.

    The "Constant" check box acts as the qualifier "const" on a c function parameter. It tells the compiler that the function you are calling will not change this setting. If you call a function prototype includes a const parameter, then you must mark this as a constant parameter when you configure the call library function node. Otherwise, I wouldn't worry on this subject.

  • Some General Questions of CVI - how does the compiler

    Hello

    I work with CVI 9.1 for more then a year during this time i ' v noticed a couple things, I would like to help me to understand.

    1. Work with several C files:
    • When I'm writing a software that uses lets say C files and files of 10 H 10: Main.c Main.h File1.c File1.h Panels.h Panels.uir and so on... I'm implementation of the function in the c file and its deceleration of writing in the file h, i ' v noticed that sometimes I get msgs of the compiler on the conflicts, maybe there's a way I know not just for the CVI?
    • Works correctly with the file UIR for example lets take the files written above, if I have sign - HAND and control led1 and I want to do SetCtrlVal in the Main.c I can implement as this SetCtelVal(MAIN,MAIN_LED1,1); but when I go to file1.c and try to do it, I get the error message that main_led1 is not a control value (I included the Panels.h) this problem happens to me a lot is there a solution? or maybe I am doing something wrong...
    • What is the best way to implement bollean var (true false) for the software? is it possible to add this var always?
    • decelerations of incompatible type: allows you to take the Fmt function for example when I'm trying to use it in another file, I get the decelerations of incompatible type with the names of the files...
    • General question: lets say I want to include in my project and I want to use its features in main.c and file1.c, I included in two files? or there is a way to include it in a single file only?

    2. to access the buttons

    • lets say that I have buttons and I am pressing on it after pressing the button I have a loop for 10 min, I want to create a button give up, but I can't press anything because the keys are "locked out" is there a way besides multi threading to implement this?

    Wow! A very broad set of issues!

    A quick response.

    • Works correctly with the file UIR for example lets take the files written above, if I have sign - HAND and control led1 and I want to do SetCtrlVal in the Main.c I can implement as this SetCtelVal(MAIN,MAIN_LED1,1); but when I go to file1.c and try to do it, I get the error message that main_led1 is not a control value (I included the Panels.h) this problem happens to me a lot is there a solution? or maybe I am doing something wrong...

    There is a basic error in your statement: the first (SetCtrlVal) parameter must be the handle Panel, which is the reference to the object in memory that is created when you call LoadPanel (). Using the name of constant sign is not correct: it may work if you're lucky and you have the Panel handle with the same value as the name of the constant, but this certainly isn't the correct way to address on a panel controls.

    Even if I don't understand the error that you declare: I expect 'the control is not of the type expected by the function' or an error of inconsistent data type (like passing an int to double check) or...

    Remember that each function that processes objects on a Panel must be aware of the handful of Panel, then either you pass to the function as a parameter, or store it in a global variable.

    • decelerations of incompatible type: allows you to take the Fmt function for example when I'm trying to use it in another file, I get the decelerations of incompatible type with the names of the files...

    I normally leave CVI #including the necessary system files: when I use certain functions like Fmt in a source file and compile ICB warns me to add the relevant include file, and it does it correctly. Operating in this way I never had problems with formatting and the I/o library functions. You can rebuild the inclusion list by removing all #includes in yous source files and compilation of the project, this should correct errors

    • General question: lets say I want to include in my project and I want to use its features in main.c and file1.c, I included in two files? or there is a way to include it in a single file only?

    You must include the file containing the definitions of the functions in all source files that use. Or you can create a general include file with all included in your project and include only this one in all of your source files

    • lets say that I have buttons and I am pressing on it after pressing the button I have a loop for 10 min, I want to create a button give up, but I can't press anything because the keys are "locked out" is there a way besides multi threading to implement this?

    It is a general rule that animates the CVI environment: during the execution of a loop inside a function (a reminder of command or another function) the system does not handle the user interface events, so that your buttons appear locked. This can be solved by adding a call repeated (ProcessSystemEvents) inside the loop: this way of all UI events are monitored and managed by the system.

    You must use this method with caution: before entering the loop, you must disable all the controls that can be used during operation (normally only the Quit button should stay active) otherwise, you can enter a situation in which other callbacks are executed during the loop that might interfere with it.

    In such a case, do not put a reminder in the stop button and the use of a global variable I have normally create a toggle button Stop and manipulate it in this way:

    While (1) {}

    ....

    ProcessStemsEvents ();

    GetCtrlVal (panelHandle, PANEL_STOP, &stop);)

    If {(stop)

    ... gracefully out of the function

    break;

    }

    }

    This argument has been discussed several times in the forums: do a search for ProcessSystemEvents returns a large number of discussions you can read

    • What is the best way to implement bollean var (true false) for the software? is it possible to add this var always?

    hot cloning. The synchronization is performed by the transfer from the source to the destination blocks which

    changed during the initial period of cloning. To avoid the loss of data on the virtual machine of destination,

    vCenter Converter can close some Windows services before synchronizing. Based on your

    settings, vCenter Converter stops the selected Windows services so that no critical changes occur on the

    source machine so that the destination is being synchronized.

    From my point of view, it works as follows:

    1.) hot clone of the source to the destination virtual computer computer

    Synronization 2) takes place directly after hot cloning, to get the delta during the initial period of cloning.

    TO

    make sure that the destination virtual machine retains all the blocks that have changed in the source system during

    the first cloning of process, select the Sync feature. With synchronization, if a change occurs

    on the source machine during the initial conversion, vCenter Converter copy to the destination machine

    after the initial conversion is complete.

    The technique that is used to nothing: Windows VSS snapshot

    Page 28

    Restrictions related to the creation of snapshots of Windows Sources

    vCenter Converter uses snapshots VSS to save the State of the source volumes during the hot cloning of physics and

    virtual machines that are running Windows. Instant VSS are also used to synchronize the virtual destination

    machine with the source machine after the initial conversion. Some of the issues related to VSS are inherited in

    vCenter Converter and can prevent the successful completion of your conversion tasks.

    3.) only the combination of the service with synchronization to stop makes sense.

    Page 53

    You can ensure that you don't lose data services that are running on the source machine. You can select

    Which services to stop before vCenter Converter synchronizes the data between the source and

    destination machine. Accordingly, the services do not result in data while the computer source and destination

    are synchronized.

    Import a Windows powered machine means that vCenter Converter copies the data from the source

    machine to the destination machine, while the source computer is still running and generate changes.

    This process is the first transfer of data. You can transfer data for the second time by copying only the

    changes during the first transmission of data. This process is called synchronization.

    What does the second time? I can do the following:

    Back to Monday from 20:00 to 24:00 the Hotcloning of the physical server to virtual.

    Then, to Tuesday 20:00 synchronize the physical server with the virtual and stop the physical server.

    I think that's not possible, two separte the first and the second stage.

    Synchronize the Destination Machine with the changes from the Source Machine

    Import a Windows powered machine means that vCenter Converter copies the data from the source

    machine to the destination machine, while the source computer is still running and generate changes. This

    process is the first transfer of data. You can transfer data for the second time by copying only the changes made

    during the first transfer of data. This process is called synchronization.

    Synchronization is available only for Windows XP or operating systems later source.

    If you resize volumes FAT or shrink NTFS volumes, you cannot use the sync option.

    Prerequisites

    Stop services of source to make sure they don't generate additional changes during synchronization.

    that could lead to data loss.

    Must serve it it I can only do this at the start time of the conversion, when the wizards to configure the conversion tasks is selected.

    In all of this means for me that with synchronization window maintaince than AI based on time, how long is the synchronization and the closure of the physical server and power on the virtual machine.

    Converter 4.2, synchronization occurs just after the cloning process and therefore changes occurred to the source during the period of cloning are also applied to the destination machine. Now, with this version of the converter, it is not possible to separate the tasks of synchronization and cloning (i.e. you can't clone the machine Monday and synchronize this Tuesday).

  • How does the virtual machine BACK to Windows?

    How does the NTVDM?  I run an old DOS program written in Fortran 77, which, with the exception of the database has not changed in 20 years.  It takes about 2 hours to start a business.  My boss told me that I can get a better computer.  Upgrading my computer 3 GB RAM maximum 4 GB will make a difference.  When I use the MEM command, I thought that the memory in use is what I take BACK used, approximately 1 MB.  Am I missing something?  More RAM can help?  Help a different CPU architecture?   The little knowledge by going to various sites, I have gained seems to tell me that dual core or quad processors are unnecessary because BACK is a single processor and use it exclusively.  How about a faster chip.  Is there a limit to the speed that is finished on the BACK.  Then addresses NTVDM maybe all these problems Unlike DOS itself.

    Thanks for your help

  • How does the trash?

    OT: Trash.

    How does the trash?

    It seems to be a "sandbox", but a reference to the storage space on each disk.

    I can't find a real situation for the trash

    If I delete a file from the c: drive or the drive e: is the deleted file stored in a different location or the renamed file right on the disc it came? (don't forget the BACK a deleted.doc file was just renamed $eleted.doc)

    Thank you

    In Windows 7, the trash is a named hidden system folder $Recycle.Bin.  There is a file with that name in the root of each of your partitions (e.g., C:\$Recycle.bin, D:\$Recycle.bin, etc.).  Within each of these folders are folders for each user in use on the machine account (there may be additional folders).

    When you double-click on the icon to the trash that is displayed on your desktop that opens is a composite of all files $Recycle.bin for the user account that is active.  In other words, you see the files you deleted all partitions of disk, but you will not see the deleted files of another user of your computer.

    If you right-click on the Recycle Bin icon, you can configure the space used for the $Recycle.Bin records on each partition.  The default size appears in about 10 percent of the first 40 GB on the size of the partition more than 5% of the balance.  As a general rule, you should leave the default size.

  • How does the task before action?

    VSM 9.1.4

    MSSQL

    Hi guys! How does the special action forward in rules CBT works?

    In this scenario, where the dependent task will go if it is enabled by the CBT?

    1. Task Implementatation is initially assigned to GroupX
    2. CBT rules:
      • If the request Type TypeA, proceed to task, set state of StatusA demand and send the task to the GroupA
      • If the request Type is TypeB, go to the task of technical approval, the Request Status StatusB value and prior approval of the Group b

    test.PNG

    When I tried to simulate this, the task of implementation was not sent to GroupA when the request Type TypeA. Instead, he was sent to the assigned group GroupX. Checked the CBT story and it seems that the rules that has task until the action was never carried out.

    Yes, that's all. I think now I know why it works the way you expect.

    I think that if TCC happens to any rule that meet its criteria of condition, it does not check any other rules in addition.

    So you specify different rules for different conditions, but not for different actions.

    And several actions (for example the Request Status value and before the task) can be combined into a single action like this:
