Table of passage to the DLL

• Table of passage to the webservice.

  I'm moving an ArrayCollection of business object collection to a WebService (.NET) method that expects an array of business objects of the same structure that I send. When I call the object a single service method is in the table. It is of the correct type. Other objects are not sent.
  I'm doing a prototype to convince the technical architect that this product is worth pursuing (which I think it is) so I don't have the time to spend a few days, IE find out these details. I'm not just being lazy here!  ;-)
  TIA

  Funny, I hate the sale of technology to managers, is not that there is work to learn what's new?

  But adurkin here, that's what you need to do. No matter what you pass to and from the service, it is to ensure that your items are consistent between flex and .net. Also, make sure that service you use in flex is set to manipulate OBJECTS defining the format of the result object for each of the functions that you have attached to your service.

  http://localhost:49753/Test_Application/App_Common/services/ProductSearch.asmx?WSDL ".
  useProxy = "false".
  Fault = "Alert.Show (Event.Fault.FaultString), 'Error' '"
  result = "OnResult (Event)" > "
  
  
  

  I would like to know if this helps, if it sends quite a bit about an example let me your email.

• Use the table 2D input and output dll

  Hi, I have a problem with table 2D used with library funtion call to get the table of DLL.

  uint16_t is defined as unsigned short, who is unsigned 16-bit in labwindows.

  In the following two codes origFrame.height is 1024, 1280 origFrame.width.

  QCam_Err DLLEXPORT FrameGrab(void* handle, uint16_t frame2D[1024][1280]) {}
  
  uint16_t * p;
  
  p = (uint16_t *) origFrame.pBuffer;
  
  Copy each pixel of the 2D array
  
  for (int i = 0; i)
  
  for (int j = 0; j)
  
  frame2D [i] [j] = * p ++;
  
  }
  
  }
  
  }

  2D array is passed to the DLL in the form table 1 d, I also tried table 1 d below but to get the same numerical results.

  {QCam_Err DLLEXPORT FrameGrab(void* handle, uint16_t *frame1D)
  
  uint16_t * p;
  
  p = (uint16_t *) origFrame.pBuffer;
  
  for (int i = 0; i)<(origFrame.height*origFrame.width);>
  
  frame1D [i] = * p ++;
  
  }
  
  }

  Both of these methods gives me the same numeric result with regard to the numbers in the output array.

  Something interesting is that the output array has the right size, but all the numbers in the table are about ~ 40, while my expected in all values table is 60.  I know, because I use this to get values of a pixel in a camera and I know that the values of the pixels.  I also used the same code in LabwindowsCVI as a normal program built as exe.  Everything works fine and I get my expected values.  So apparently miss me something here, when I changed the settings to make dll.

  What I've done wrong?  Thank you very much for your help!

  Best,

• How to read the table of string returned by the DLL

  I developed DLLS in labview that takes 2 input parameters as a string and returns an array of strings in return. How can I read back this array returned strings in labview? I tried to return a string and I can't able to read. But how to read a table?

  Is the signature of the function – void GetLoginInfo (char [] DBPath, char [UserName], LStrHandleArray * table)

  Shrinivas

  I found the solution. When you configure the node to call a library function, the argument (in which we expect an array of string) type should be chosen as "Adapt to the Type" and data format to be "pointers to the sleeves.

• The DLL call fails when DLL uses a wide range

  I call a C++ dll in LabVIEW 32-bit on Windows 7. I kept getting error 1097 and finally understood it is because the dll uses two large paintings of 5 MB each. The tables are initialized in the constructor of an object, malloc is not used, or whatever it is. If I do the smaller berries, then everything works fine.

  The problem is not difficult to work around, now that I know what is the cause, but can someone tell me why a dll using a lot of memory would be a problem? I feel that 10 MB is really a lot of memory to use on modern computers.

  OK, you can test the appeal of the DLL in a Visual Studio test harness?

  In addition, in case you haven't seen another 'DLL error 1097' son type, here are a few. The cause of 1097 in your case can be illuminated by a multitude of courses of troubleshooting:

  Call dll error 1097

  Error code coming 1097 in DLL call

  error 1097 after the call dll function that allocates memory inside

  1097 error in the transition from table from C++ DLL for LabView (seems very relevant, although long)

  I know there are a lot of reading, but there is a good chance that the magic trick is in one of these threads already. We will ride on the shoulders of their work.

• tables as input for the shared library function

  I played with the call of LV VI using matlab.

  So I built a simple VI which returns an integer as input and multiply it by 10, I then put in a shared library and named it MATLAB - well.

  Now, I tried to do the same thing with a table - I want to send a picture to the VI and multiplied it by 10, but when I build the .h file, it seems that the function expects get table of entry AND exit of table as inputs.

  so, how I can build a shared library VI who gets an array (of a constant size if this is important) and multiply it by 10?

  Thank you!

  A function in a DLL can only return a scalar value, not a table, no matter what languages are used. To return an array, instead calling it allocates the array pass a reference to the DLL and then after the function called the referenced table table contains the new data. This is why there are two parameters - the input array (actually a pointer to it) and a pointer (reference) to the output array. You must change your code in MATLAB, there is nothing you can do about it in LabVIEW. EDIT: Also note that it allows to re-use of the input as an output table, optionally passing a reference only to the table of entry and then by changing that. You can do it in LabVIEW by configuring the setting table as input and output.

• Sinc filter using the DLL implementation

  Dear all,

  I'm trying to implement a sinc filter to a data flow that I receive from card FPGA. The C code is already working and now I'm trying to do is to implement the same algo on LabVIEW or make DLL and use it and I'm doing the later approach (don't know which one is better, any ideas?). I use this tutorial and it works very well for me in the case of the same example IE multiplication please see the VI attached.

  I'm getting streams of raw data in the .csv file, and then I like to read this file. So what I have to do is apply a sinc filter so that every 32 points in this data set will be 1 sample for my position. I enclose you an example of a .csv file for data, a txt file of code C (for just to give you an idea of 3rd order) who work already, my dll and VI.

  More specifically I have problems about the selection of parameters for the DLL for example what should I choose in the settings of the DLL LabVIEW function that corresponds to "unsigned char * data" as well as for others, as written in the C code. If someone can provide me with some VI he created to implement the sinc function or some ideas it would be also great.
  Any help or advice you guys will be highly appreciated.

  Kind regards

  Kuhn

  There are a lot of discrepancies between what you do in your VI and that your text file watch is C code.

  (1) the order of the parameters is VERY different.

  (2) you are using int64 in the LabVIEW diagram, but int in C code. Under 32-bit Windows and 64-bit (and also Linux), an int type is ALWAYS a 32-bit value.

  (3) read you in a table 1 d of channels and proceed to the node library call as native data. This requires a handful of LabVIEW LabVIEW handles string table. Expect a VERY big difference to byte array pointer in C code.

  You convert the strings in a byte, and then configure the node library call to pass it as an array of integers not signed 8-bit, passed as a pointer of table data.

• How to call a DLL function that has need of an array initialized structures which can be written in by the DLL?

  I need to call the following function in a C DLL:

  __declspec (dllexport) int MSIL_EnumSpectrometers (SPECTROMETER_ID * spectrometers);

  where the only parameter is a pointer to:

  typedef struct
  {
  tank model [32];
  series char [32];
  Channel int;
  } SPECTROMETER_ID;

  Before LabVIEW 2011 I would use a CIN allocate the memory and call the function, but in LabVIEW 2011, the INC has been deleted and I have to use a library function node call instead. When I go to set the parameter, it seems that I need to set the type to "Adapt to the Type" and data for 'Pointer to data in table' Format, then pass an initialized array of SPECTROMETER_ID with the many elements he so the DLL can fill the table with data. (See the attached picture.) When I do that, however, it blocks LabVIEW desktop.  I guess it is because the DLL is corrupting the memory space of LabVIEW, but I don't see why, because I'm basically passing in a void pointer to an array initialized in the right size. Note that the first node of NSI returns the number of elements required in the table.  Anyone have any idea what I'm doing wrong here?

  In LabVIEW, when a table is in a cluster - cluster don't detain actually table but sort of a pointer that points to the table. If you need the cluster to contain 32 to 32 Add to the cluster. See the VI attached to how it's supposed to be done.

• Table of double filled by DLL contains odd values

  Hello everyone

  I'm working on a DLL call which must resize and fill in an array of double named "values" (2nd to the last parameter). I defined the signature as follows:

  _declspec (dllexport) uint8_t readDoubleArray(uint8_t handle, LStrHandle lPath, int64_t startTime,        int64_t endTime, DblArrHdl *values, LongArrHdl *timebase);
  

  Where is DblArrHdl

     typedef struct {      int32_t dimSize;      double doubles[1];        } DblArr; typedef DblArr **DblArrHdl;
  

  In the call, I read copies of a database and resize the table double as follows:

       int size = doubleArray.size();
  
        if (NumericArrayResize(0x0A, 1, (UHandle*)values, size) != noErr) {           setLastError(MG_ERR_LABVIEW_ERROR, "Failed to allocate memory");          return FALSE;     }
  

  I set the size and copy the values:

  (**values)->dimSize = size;for (int i = 0; i < size; i++) { (**values)->doubles[i] = doubleArray[i];}
  

  When I use the DbgPrintF to validate values, it gives me a value of about 120000 is correct. However, when returned by labview table contains strange data, such as 5.38564E - 315. Here's impression on the array of 'values' once he was through the DLL:

  

  Here's how I wired it, ignore the grouping, it occurs in the array of values that comes out of the call to the DLL.

  

  I have no idea how this can be. I followed the examples on the site. I also tried the normal DSSetHandleSize, but it changed nothing. No idea what I was wrong?

  Thanks in advance,

  Vincent

  Hi again,

  Vincent, you have a problem with the alignment. Simply add #pragma pack (1) before the table:

  #pragma pack (1)
  typedef struct {}
  dimSize of Int32;
  float64 elt [1];
  } TD2.
  typedef TD2 * TD2Hdl;

  and everything should be OK.

  See the example as an attachment.

• 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.

  Batya

  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.

• Competitor not starting not not to DR after passage in the

  Hello

  We have successfully configured recovery disaster for 11i ebs on windows environment.

  Redo log shipping and applying normally and its working fine.

  After the passage of the primary on the eve, we synchronized with the new primary database application services.

  But while watching the concurrent managers, we are facing questions.

  In the concurrent Manager log as its display error

  Could not contact Service Manager FNDSM_ORACLEAP_HRDR. The TNS alias could not be located, the listening on ORACLEAP process could not be contacted or the listener cannot generate the process from the Service Manager.

  Could not contact Service Manager FNDSM_ORACLEAP_HRDR. The TNS alias could not be located, the listening on ORACLEDB process could not be contacted or the listener cannot generate the process from the Service Manager.

  We have made the steps below but make even persistent.

  (1) connect apps/primaryapps

  (2) exec FND_CONC_CLONE. SETUP_CLEAN;

  (3) validation;

  (4) run cmclean.sql

  (5) run on nodes DB, CM & WEB autoconfig.

  (6) run @%FND_TOP%\patch\115\sql\afdcm037.sql sccripts also.

  (7) we have correct host entries in the system hosts file.

  Kindly help me to solve this problem.

  
  

  Thanks and greetings

  Hello

  The problem is solved now concurrent Manager is up and running after the digital switchover.

  Solution:

  After the passage of the database:

  ------------------------------------------

  Complete the Configuration of database:

  ----------------------------------------

  connect the apps/primaryapps

  SQL > exec fnd_net_services.remove_system ('HRDR');

  SQL > commit;

  SQL > exec fnd_conc_clone.setup_clean;

  run the automatic configuration on db

  lsnrctl stop STHRDR

  lsnrctl start STHRDR

  Synchronization of the application:

  -------------------------------

  disable the listener applcaiton both on the odes before running the automatic configuration.

  Run the autoconfiguration on cm node service

  Run the autoconfig on the node of the Web

  Check the node values using query below:

  ----------------------------------------------------

  Select nodeName in fnd_nodes;

  Select CONCURRENT_QUEUE_NAME from FND_CONCURRENT_QUEUES where CONCURRENT_QUEUE_NAME like '% FNDSM'; ---> to the result of the query, for me web node hostname only came so I ran script below.

  @%FND_TOP%\patch\115\sql\afdcm037.sql ---> this script updates the table with the details of the cm node

  now, it seems very well.

  Select CONCURRENT_QUEUE_NAME in the FND_CONCURRENT_QUEUES where CONCURRENT_QUEUE_NAME like '% FNDSM ';

  Then restart all servers.

  Now start the database and applications.

  Problem will solve itself.

• Beyond the Tables... understand the DIV :)...

  Hello

  Unfortunately, I was taught Dreamweaver sorta backwards and have always used tables for layout.  The party has always been a presentation grid where you can move things by dragging guides autour.  He works most of the time, but I am determined to go beyond.

  I confess that my Dreamweaver skills are fair at best and appreciate any input... Please be gentle

  Here is the current Web page: http://www.outposticearena.com/

  Here's my (much improved with added animation) draft... and still confused about the layout... http://taffyproductions.com/test/

  (1) why are there lines between my sidebar1″/nav?  What are the rules css determine their spacing and size?

  (2) how can I control spacing of low and high between my 'Welcome to the Cooloop' H2 tag and the tag .p underneath?

  (3) I have 4 images/links in the DIV of sponsors.  I want central / SPACE.  How can I do this?

  Thanks again!

  1. in style.css line 111

  Li ul. NAV

  {

  border-bottom-width: 1px;

  border-bottom-style: solid;

  border-bottom-color: #666666;

  }

  Remove the border and went to lines

  2. at the beginning of style.css, place the following code

  * {margin: 0; padding0 ;}}

  Each browser has its own default style rules. If they were all the same rules then we could live with it. Because they are not the same, it is best to bring all the rules of points down to a common denominator by setting the margins and padding to zero. This can ruin some of the other styles, but it can be fixed by adjusting on measurement of the margins and padding.

  3. first of all we must reorganize our markup

• How can I display the table of contents for the iPod Touch to 6

  When I opened first of all iPod Touch Users' Guide, I used the table of contents (TOC) to locate and access sections in the manual. But, after looking through the manual for awhile, I tried to return to the table of contents, but it wasn't there! I have tried various things to see if the table of contents are being hidden, or if in some way, it has been deleted. Anyone can shed light on this mysterious event?

  What is the version of iBooks that you speak? There is an online version here: https://help.apple.com/ipod-touch/9/ Aha, I see the table of contents on the left disappears if you zoom before or make the narrow window and reappears if zoom you out or make it larger.

• Wheel rotation during the passage of the apps

  Hello

  I frequently meet the spinning wheel during the passage of the apps. For example an app can do one, but open window have not been used for a while and then when I click on the window to use it I get the wheel spinning for a few seconds.

  I am running Yosemite 10.10.5 on a MacPro Mid 2010) with 16 GB of ram and 12 GB available on the 300 GB SSD drive. I just realized that maybe space on the boot drive may be the cause, so I'll empty now and update if there is no change.

  Also, my SSD is a 500 GB Samsung SSD 840 EVO media and I think that the TRIM is not enabled? I read that TRIM was not based with SSDS of third party on my machine and was picking up information contradictory as to the time it was a problem or not. The lack of TRIM could be the cause of the spinning wheel?

  Duane

  You ran a 'cleaning', 'optimize' or 'speed up' apps on your Mac?  Have you installed an antivirus software?

  The 12 GB of free space must be sufficient and not to be the cause of the problem. Don't let him get any small however.
