• with image byte order

  Hi all

  I am the acquisition of the Lumenera USB 2.0 camera images (16-bit format). When I use the transformation of 'image to the table' IMAQ I get all negative pixel values. I think that the problem is related to the wrong byte order (big vs little Endian). No idea how to solve this problem?

  Thank you!

  Andrey,

  I went throuhg this yet, you were right, this seems to be the problem. However, in the processed images, the histogram of the image seems "scanned" as a collection of functions delta, rather than be a function continues. Any ideas why this would happen?

  Thank you!

• byte order mark

  I saw asked at another time, but he has not actually answered. In dreamweaver when you include php in a Web page files, such as creating a temple, unicode automatically inserts these byte order marks. In preferences, you can uncheck an option that includes the byte order marks, but when they are disabled, they still manage to appear, causing random spaces in your formatting. This is a problem because it substitutes for the CSS and the characters are hidden until you view your page in a browser or in Live view mode. If anyone can answer this question it would be greatly appreciated.

  I started, ensuring that coding was correct and that the Nomenclature were not included, well. I do thank you for trying to help me.

• How to manage the padding issue & bytes - ordering when you change the resource (PiPL) file in windows?

  Hi all

  I just started programming sdk photoshop. I noticed that the resources provided by Adobe Guide recommends to develop dialogs using Mac ground language and converting it into window using the CNVTPIPL resource file. EXE. If you use a windows resource editor, padding and byte-ordered issue must be handled by the programmer himself. Since I'm not sure what is the architectural differences between a PC and a Mac, can someone explain to me exactly how padding and byte-ording problems are handled under the windows resource editor? It would be good if there is no concrete example.

  Thanks for any help!

  You really shouldn't edit resources directly if you can avoid it.

  Simply modify the .rc files or Betty and recompile.

• BUG: Split then join reverse byte order - sometimes

  I created a simple to serialize an array of bytes I32 and fell VI on this interesting bug. This code runs in 32-bit SP1 of LabVIEW in 2014, fully patched. Save the parts two attached and run TestI32ToByteArray.vi. Note that the 6 and 7 at the end of the table are reversed. If you explore the data around, everything looks good except the string split on the last low word is reversed. Any ideas?

• Sequencefileload freezes when calling DLL

  Hello

  I TestStand 4.1, and when calling a DLL on the MainSequence, everything seems to work fine, but if I call him on a SequenceFileLoad TestStand freezes on this step.

  What could be the problem?

  Kind regards

  Daniel Coelho

  Daniel,

  In fact, printf() can be the problem.  Because you are calling it in DLLMain, there are additional considerations you need to keep in mind.  Microsoft has a great page on these considerations here: http://msdn.microsoft.com/en-us/library/ms682583 (VS.85) .aspx

  Some excerpts:

  The entry point function must perform only the tasks of termination or simple to initialization. It should not call the LoadLibrary or LoadLibraryEx function (or a function that calls these functions), as this can create dependency loops in the DLL load order.

  Calling functions that require one dll other than Kernel32.dll can cause difficult to diagnose problems. For example, the calling user, Shell and COM functions may cause access violation errors, because some functions to other components of the system load. Conversely, calling functions of these courses of termination can cause an access violation because the corresponding component may already have been unloaded or errors not initialized.

  I'm sure that printf() is a shell command.  Also, while loading the file in sequence, it is likely that TestStand loading of DLLs or COM objects at the same time, which could conflict with a code that you have in DLLMain.

  Apart from that, Microsoft strongly recommends against any unnecessary code in DLLMain.  If this problem only may not be something to do with the products NOR, but more practical copies creation of DLL in general.

• Convert number in reverse byte array?

  How convert a value, said 10,000, in a table of 4 bytes and then reverse the byte order? Is there a function for this or? I can do it easily in LabVIEW, but I wonder if it's possible in TestStand.  Thank you!

• VC ++ dll in teststand problem

  I have a third party DLL probably DEVELOPED in VC ++. I have even the files .h and .lib for this DLL. I want to study how this DLL can be integrated in TestStand. The problem is that when you use C/C++ adapter the TestStand concludes that a single function in this DLL and it seems to be like Class::Function. I tried to find a solution in this forum, but it seems that the solutions have access to the source code of the DLL.

  I know well develop CVI and their use in TestStand DLLs. That is my only method of CVI programming a soul to this DLL if I want to use in TestStand? If I want to communicate with the third party provider, they need to add DLLS in order to get it to work in TestStand?

  Kind regards

  Hello

  I looked on the dll. Well TS do things. Because the GetVersion is the only public and static function inside your class.

  This dll provides a class. I think you should write your own dll-wapper around it. You must create the object next to our packaging. Then you must create wrapper functions when you access the members of the group.

  hope this helps

• LabView crashes after calling DLL

  Hello

  I'm working on a library that makes calls to the other dll, which is linked dynamically.

  I have to do this, customize the DLL search order before the call and add a few custom directories (where are the dll called).

  The called code works very well, and doesn´t in the DLL called memory leak, however LabView is suspended.

  It took me a long time to understand this, so I hope this helps someone in the future. Below is the solution.

  LabView uses its own research agenda DLL, so beware of assistance call "SetDefaultDllDirectories" regarding the whole process and LabView DLL management function will burst.

  Allways avoid using flags in the LoadLibraryEx.

• Series read byte command change

  Hello

  I'm new to Labview and I'm reading the speed and torque of a couple of reference via RS232 transducer. I need to read the data as a frame of 6 bytes. I followed the Protocol provided by the manufacturer (3 bytes concatenated + some calculations give couple and 4 and 5th concatenated byte gives the speed and the last byte provides the power supply on the torque sensor).

  When I re - run my code, to change the order of the bytes. In the two screenshots, I have attached the correct order (with 128 in the first byte). But sometimes, when I run the code changes of the order, so instead of 0 1 2 3 4 5 go, it reads 3 4 5 0 1 2 (or else), that ruin my calculations.

  I tried switches ON and OFF the stop character and by changing the flow control settings, but it makes it worse or is not good. Forgive me for my lack of knowledge in Labview or basic serial communication.

  I would appreciate any information about this. Thank you!

  Kind regards

  The probe is the streaming of data.  This means that it continues to stream without your vi have to ask all the data.  When you read data from the stream, you need to know where is the first byte of the frame.   You must be synchronized with the data structure.  Do you know how many times he transmits a data frame?

  Document you posted says the 7 Bit (MSB) of each byte is used to synchronize the image.  First byte has Bit7 = 1 and the rest of the bytes have bit7 = 0.  This means that the first byte will always be a value equal or greater than 128.  The other bytes will always be 127 or less.

• How to use global variables from a dll in another (not multi-threaded)

  With LabWindows/CVI. I try to be compatible with legacy code, so this isn't the best way to do things, but it saves me some headaches.

  I have a project/.dll called "GlobalBlock" that contains some parameters used widely throughout the program. The entire program consists of several DLLs, for the purpose of encapsulation.

  GlobalBlock.c contains:

  menu_sdef G_setprefs = struct
  {
  ... stuff

  };

  sys_fileheader_sdef Level1Version = struct
  {
  ... more

  };

  struct G_sys_flags sys_flags_sdef;

  In the dll that owns the variable, use the _export on this qualifier. This will ensure that it is placed in the list of the interface dll. In the application (dll or other) that wants to make reference to that variable, use the qualifier _import on it. This tells the system to use the associated import library that comes with the dll in order to resolve references running.

• Registering a dll file to start the service HID Input Device

  Hello

  I would like to register the dll located in my System32 hidserv.dll. However, when you enter the command 'regsvr32 hidserv.dll' I have an error message indicating that: "hidserv.dll was loaded, but the DllRegisterServer entry point was not found. This file cannot be saved. "

  How I then save it, knowing that I checked that this file is not corrupt?

  I need to register this dll in order to start the "HID Input Device" who stubbornly refuses to start despite an integrity check in the registry.

  The system event viewer specifies that:

  "HID Input Service service terminated with the error:
  Error 126: The specified module is not found. "

  I already tried to extract hidserv.dll, mouclass.sys & mouhid.sys sp2 and sp3 even to put them in the C:\Windows\System32 directory, but I had no change.

  The files I have place in my SYSTEM32 have the following version:
  Hidserv.dll: 5.1.2600.5512
  Mouclass.sys: 5.1.2600.5512
  mouhid.sys: 5.1.2600.0

  but the service still does not start even after rebooting. The 126 error continues. Is there other files to extract / expansion?

  I checked the integrity of all stakeholders key in the registry (for example, to have the "ServiceDll" key whose value is "% systemroot%\System32\hidserv.dll" in the settings of the service HIDserv ControlSets), but nothing more.

  I give you an export of the current CS:

  By analyzing the Observer newspaper of events more deeply, I could identify the date on which took place the first concern. The problem is dated, 18/08/2010 at 11:59:17 (it sticks with the conclusion of the first concern of losing control of my volume on my Logitech G110 keyboard also control buttons). I don't remember having a particular to this date on my system change, except perhaps a Windows Update automatically.
  I could not try a system restore, knowing that the RP oldest I have is dated 20/08, so downstream of the original problem.

  I ran a File Checker sfc/scannow system with my Windows XP Pro SP3 (current version of my system) installation cd. I've been thinking about it since a cd to install Windows XP Pro SP2, but better is worth twice more than once. I also realized a CheckDisk, but these two operations have not changed the problem.

  You will find export of address following my diary of events on the system.

  I have completed all of the tasks (start, replacement dll, see registry, SFC,...) while logged on sessions 'standard user', 'administrator' and even as a 'SYSTEM' (NT Authority), but in none of these configurations, it was possible for me to start this service. If I come to you, is precisely to avoid passing through a repair using the cd which would have made me lose a lot of time. I don't usually do the use of support services, in general the case has already been handled and the response or similar cases are on the web. But now I feel like in front of a technical impasse. I appeal to your specific skills to do what is necessary for good service restarting without using a remedy that eventually a reinstallation of the system.

  It you want to check my configuration, you can find it here.
  If you need more information, feel free to contact me. I would be happy to answer them.

  Until then, thank you very much. Kind regards.

  First of all, the hidserv.dll is not a DLL that can be recorded.  You can try all day long, but it will not be because he is not on the list of DLLs that will be or must be registered.  There is a list, and which is not on it.  (well thought of).

  Your problem is in the registry with the HidServ, section ServiceDLL parameter.

  You have a space left in the key ServiceDLL.  In regedit, it should look like this:

  %SystemRoot%\System32\hidserv.dll

  Yours probably looks like this in regedit:

  %SystemRoot%\System32\hidserv.dll

  See the space left?  I don't know how it got that way (perhaps something that was installed for these humans), but I know that if I put a space in front of me and restart my system, HID service not start and give me an error 126 as you describe.  He has no idea about the problem in the log events.

  With space on the left, the specified module really not found because there is no such thing as the path (with the space to the left).

  Your registry export reveals this problem.

  Yours looks like this:

  [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\HidServ\Parameters]
  "ServiceDll" =hex (2): 20, 00, 25, 00,53,00,79,00,73,00,74,00,65,00, 6 d, 00, 52, 00, 6f,
  00, 6f, 00, 74, 00, 25, 00, 5 c, 00, 53, 00, 79, 00, 73, 00, 74, 00, 65, 00, 6 d, 00, 00, 32, 33, 00,------.
  5 c, 00, 68, 00, 69, 00, 64, 00, 73, 00, 65, 00, 72, 00, 76, 00, 2nd, 00, 64, 00, 6 c, 00, 6 c, 00, 00,------.
  00

  It should look like this:

  [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\HidServ\Parameters]
  "ServiceDll" =hex (2): 25, 00,53,00,79,00,73,00,74,00,65,00, 6 d, 00, 52, 00, 6f,
  00, 6f, 00, 74, 00, 25, 00, 5 c, 00, 53, 00, 79, 00, 73, 00, 74, 00, 65, 00, 6 d, 00, 00, 32, 33, 00,------.
  5 c, 00, 68, 00, 69, 00, 64, 00, 73, 00, 65, 00, 72, 00, 76, 00, 2nd, 00, 64, 00, 6 c, 00, 6 c, 00, 00,------.
  00

  In your, you can see I have stuff in bold print on the front of the chain: 20.00...  In hexadecimal, is a space and a null value (null value is correct).  You must use regedit to get rid of this leading space (20 hex), and don't forget that, in the settings section, the first character of the value ServiceDLL is the % sign (which is a hexagon of 25).

  You can, of course, just change the string, delete everything that is there, and retype the value if it looks like this without spaces attack/crawling:

  %SystemRoot%\System32\hidserv.dll

  The HID Service will not start if you come to make the changes and try to start the service.  After making your changes, you need to restart, you can check it out, and then start the service HID.

  Do not guess what the problem might be - understand and resolve it. I need YOUR voice and the points for helpful answers and propose responses. I'm saving for a pony!

• Byte representation of numbers in PL/SQL

  Hello
  
  I develop a customer SMPP (short Message Peer to Peer) in PL/SQL (10g) and I don't know how to convert numbers in the format requested by the specification of the Protocol (v 3.4).
  (If someone is enterested, the specification document can be found here: here )
  
  According to the specification, the numbers should be represented as "a value unsigned with the number of bytes (in our case, 4 bytes). The bytes will be always sent MSB first (Big Endian)".
  
  So far, I found two examples of code on the Internet, showing one in PHP and one in Java.
  
  In the PHP example, integers are transformed by the function 'pack' in unsigned long (always 32 bit, big endian byte order), then the result is written to the socket. The code where it is:
  
  $header = pack ("NNNN" $v1, $v2, $v3, $v4);
  fwrite ($this-> _socket, $header, 16);
  
  In the java example, numbers are arranged in arrays of bytes by using the following code:
  
  int OCTET_MASK = 0xff;
  int i = (int) data;
  Byte [] intBuf = new ubyte [4];
  intBuf [3] = (byte) (I & OCTET_MASK);
  intBuf [2] = (byte) ((i >>> 8) & OCTET_MASK);
  intBuf [1] = (byte) ((i >>> 16) & OCTET_MASK);
  intBuf [0] = (byte) ((i >>> 24) & OCTET_MASK);
  
  They are then concatenated into a byte [] array and then again written to the socket.
  
  Is there a way to get this functionality with PL/SQL?
  
  Thank you in advance,
  
  Max

• Distribution with only. DLL?

  Is it possible to distribute a package of application that uses a database with only the Oracle.DataAccess.dll file connection in the /bin/ application directory? We try to minimize the pain and be able to distribute the software WITHOUT the user to install anything except our software.

  Hello

  Well well, just because something is in a .NET DLL does not mean that it cannot have external dependencies as well. For example, there are DLLs in the .NET Framework library that depend on external (unmanaged) DLLs in order to call native methods.

  I don't know what to say on exactly why bit - it's because there are additional dependencies. Using Instant Client 'Lite' with ODP.NET is about a distribution of 30 MB.
