• Opal kelly builders and LabWindows/CVI

  Hello, all.

  I try to get a Council Opal Kelly XEM3005 running with LabWindows/CVI 8.5.

  I have been in touch with Tech Suppt of OK and overthrew the original questions of type 'bool '.  After (at the recommendation of OK) with "char" types, I can now include the headers without errors.

  There are, however, a new problem:

  When I call the constructor function, which should return a pointer to a type of "okFrontPanel_HANDLE", I get an error for a prototype missing for initialization.

  Dredged in the .c (pp) file I found the following:

  Hi tomii,.

  Looks like you posted another very similar thread on the compilation of mistakes with the DLL of your Opal Kelly here. I follow upward in this thread to help get traction with those questions.

• Windows 7 Starter Edition and LabWindows/CVI

  Hello

  I have two questions/problems with an application written with CVI 9.0.1 and CVI 2009 respectively Windows Vista professional.

  First if I have a distribution of my software package (or a version of a sample distribution package) and you want to install it on a netbook with Windows 7 Starter Edition Setup displays the following error message:

  "This product does not support Windows Starter Edition."

  Is this just a restriction of the installation program, or CVI will never support the Starter Edition?

  We often sell these netbooks as well as our units of measurement as an input/output device. But I think that in a future close all netbooks will use Windows 7 instead of XP and above all the Starter Edition.

  So if it is not taken in charge this will help upgrade netbooks to Windows 7 Home Premium? I have already tested Windows 7 Professional and it works, but I do not want to install Professional on a netbook...

  My second question also the Starter Edition.

  I'm building a kit of distribution of working space example "interp.cws" (curve fit and Interpolation) with the runtime engine installed in the application directory. If I run the .msi instead of the setup.exe package then the software has been installed on the system.

  So I can run the software, and it seems to work. But if the software calls a function in the library of analysis advanced (for example, the Spline Interpolation) it does not work. With remote debugging I discovered that there was a nonlethal runtime error "the analysis DLL library is not found or could not be loaded" during the spline function calls.

  The same sample works fine with Windows 7 Professional.

  Is this also a restriction of the CVI, and will be the reason (or one of the reasons) did not support the Starter Edition?

  Or is there a workaround for these errors?

  Best regards

  M.S.

  National Instruments supports Windows 7 Starter; However, just as now, our facilities are defined to stop any Windows Starter Edition is detected.  This is because XP and Vista Starter Editions were marketed to emerging markets and had severe limitations of performance.

  You should make sure that your specific product supports Windows 7.  If this is the case you can follow the instructions in the knowledge base

• LabWindows CVI GUI problems on XP Embedded

  I developed a CVI 9.0 application that works fine on XP Pro.  On an XP Embedded system, however, when the application is started the GUI came but it appeared that all the text labels are absent and some controls showed no right.  I could click on the controls and the application does what it was designed to do.  I thought that maybe some of the font files had disappeared so I copied all the files from XP Pro system fonts and installed on the XP Embedded system but it has not fixed the problem.

  See the attached screenshots...

  I developed an application with CVI 6.0 for a XP system eight years ago and it works fine on the XP Embedded System.

  Has anyone seen this problem?

  I solved the problem simply by going to regional & Language Options Advanced and set to English (United Kingdom), then back to English (United States) and that some how my problems solved.

• How to remove the additional window when I start LabWindows/CVI or will execute my program?

  For a short while (maybe a week or more), I get a small extra window behind my request. Also, when I start LabWindows/CVI, I get the same window. It is a small blank window with the same title as the application. Press close (X) closed the application too.

  I don't remember seeing this before and that he doesn't know what has changed on my PC. It also happens with old LabWindows (previously compiled) programs, it seems that something in Windows has changed.  I use Windows XP and LabWindows/CVI 9.0.0 (348).

  Thank you

  Rob

  Hi Rob,

  The window that you see is part of the CVI. It is the parent window for all windows of the CVI so much in the environment and execution. As a general rule, this window is hidden way off the screen so that you don't even know it's there. But some video cards have a parameter that requires all windows off the screen to move to the screen. Take a look in your video card settings to see if this setting exists on your pilot. If so, then disabling the setting will allow the window to hide off screen.

• difference of initial value of string between the steps in the process and an external instance of LabWindows/CVI

  Hello

  I'm curious to know what I see using TestStand, LabWindows/2013 2013 with regard to initial in TestStand string values when you perform the steps in the process or an external instance of LabWindows/CVI.

  I have a step (CVI) string value that is used to check an array of characters stored in an EEPROM to test.  I pass on the Step.Result.String in the CVI by reference.  I then read the table charater of the EEPROM in the chain (Step.Result.String).  The string is then compared against the limit as specified in the test step breast.

  When I run this test step to perform the steps in the process selected in the popup Configuration of the adapter of LabWindows/CVI, it seems that the memory allocated for the string is filled with null characters.  Which is what I expected.

  When I run this test step to execute the steps in an external instance of LabWindows/CVI iselected of the Configuration of the adapter of LabWindows/CVI popup, it seems that the memory allocated for the string is filled with something else.  That is not what I expected.  For example what I see in the memory, it's the first characher is one byte NULL but the remaining bytes are some other values, as shown below:

  F0 00 AD BA 0D F0 AD BA 0D F0 AD BA 0D AD BA 0D AD BA 0D BA 0D AD F0 F0 F0
  F0 AD BA 0D F0 AD BA 0D F0 AD BA 0D F0 AD 0D AD BA 0D AD BA 0D F0 F0 F0 BA...

  In my code I make sure to write a null character in the following location table charater I just write in the chain so I have no problem with the test is working properly.  I have remove the writing from my code null character and was able to verity that the test passes when executing the steps in the process and fails during execution of the steps in an external instance of LabWindows/CVI.

  The returned string contains what I wrote for her, and then the rest of the string is filled with the values that are in the memory allocated for the string.

  Here's my Question: is this the expected behavior for the original string values in TestStand between both types of stage performances?

  Thank you

  Chris Young

  In general teststand not Initializes the unused portion of the string buffer, so it is expected that the values of the memory after character no endpoint will be different, or even to each call. If you happen to be get zeros after the null terminator which was probably due to random character (i.e. the memory allocated just arrived already having zeros in there) or perhaps a debug setting you use perhaps in the Visual C runtime (if you are debugging the process in visual studio or modify visual C runtime heap parameter). TestStand is not initializaing memory after the null terminator character in both cases (I checked the code).

• Suddenly have a problem starting LabWindows CVI 7.0 on XP system

  I've been using LabWindows CVI version 7.0 on a Windows XP operating system.  Earlier in the day, I changed my system screen resolution and was working with the applications.

  Everything seemed to work, but at some point, I finished the session, then restarted.   Instead of leaving, I have a Message popup that says "Index passed is out of reach" and the CVI application closes.

  I tried to reinstall CVI original cast CD.  When everything was installed I get the same message when you attempt to start the CVI.

  Anyone have any idea what could be wrong?

  I vaguely remember having a similar problem a few years ago, because I think that something in the windows registry fixed - but I'm not sure.

  Thank you

  Well, I tried to remove the entries from registry for National Instruments.  After starting and seem to work.

• problem with LabWindows CVI

  Hello I m trying to create a Setup program for an application created in a previous version of Labwindows CVI which one don't know locks I get just the file sources, I m working with the 2010 version, the problem is that the application is running in debug mode but when I run in release mode the application does not work only the icon in the taskbar is indicated but the GUI never appears, someone can help me with this

  Thanks for your help, the problem was not with the code and was not with the RT engine version, was a misconfiguration in the compilation release configuration, I myself do not add external sources dll´s and lib´s in the plug-ins option in the settings of the target

• LabWindows CVI 2010 and GetProcessAddress()

  I use v10.0.1 Labwindows CVI 2010 after the upgrade to version 2010 CVI v10.0.0. After the upgrade, I have a compilation error of a statement that compiles fine in the previous version. The error is:

  «= Operands are types illegal "pointer to __stdcall int function (int, pointer to char, char pointer, pointer to char, int, pointer to char, pointer to char)' and"FARPROC".»

  What causes this error is the following statement in the code:

  my_FP = GetProcAddress (dll_handle, "DLL_FUNCT");

  and the definition of my_FP is:

  int __stdcall (* my_FP) (int x, y of char [], char [z], char * m, int g, char A [], char [] B);

  (the parameters and the function names have been changed for simplicity)

  As I said, this line compiles fine in the 10.0.0, version but not in 10.0.1. Y at - it a specific update to the compiler that will cause this error? What can be done to fix this?

  I thank very you much for your time and your help.

  You are right. This was caused by a change in the SDK Windows CVI headers that took place in the 2010 SP1 version. The change has been associated with bug fix #275934. Unfortunately, this bug fix introduced this unwanted side effect to require a cast for any function that returns a function (such as GetProcAddress) FARPROC poinrter. On reflection, this side effect is unacceptable and needs to be fixed in the next version. This is followed internally with bug ID #336341.

  I'm really sorry for this inconvenience. Until the problem is solved using the typedef & cast you have already implemented is a valid alternative.

  Another solution, if you're worried about other projects or other functions, where this error can also appear, is to edit CVI2010\sdk\include\windef.h and replace the following definitions of FARPROC (line 226 and 230, respectively):

  typedef INT_PTR (away from WINAPI * FARPROC) (void);

  typedef int (away from WINAPI * FARPROC) (void);

  with:

  typedef INT_PTR (away from WINAPI * FARPROC) ();

  typedef int (away from WINAPI * FARPROC) ();

  This will avoid the problem throughout a facility given to the CVI.

• I have a problem connecting the Netgear model No. RPV3000 Extender. So I can not see my network_EXT computer and therefore cannot link to this Netgear

  I'm AT & T PACE router connected to Internet. However, I have a problem connecting the Netgear model No. RPV3000 Extender. So I can not see my network_EXT computer and therefore cannot link to this Netgear. I tried to use another network with the name of my network_ext and provide the same passkey that my router, but it was impossible to connect to the Extender.

  I would appreciate it, if I can get any suggestion/help to bind and connect to this extension of NETGear. I have WIndow7 system on my computer.

  Thank you

  Harshad João

  First, make sure that the netgear device is not a router.  An Extender is very good.  You can't have more than one router in a network.  Also make sure that if you use the router wireless integrated into your modem, the router ONLY in use.

  There is a very specific configuration for the Extender.  It should have come with detailed instructions.  If you can't find them, call Netgear for assistance.

• Problem with AE and SOUL - dynamic links?

  I use after Effecs CC and I try to open the file .aep in Adobe Media Encoder CC (for export to MPEG format).  I get an error stating: "Could not connect to Adobe After Effects.  Check that the Aobde After Effects and Adobe Dynamic Link components are installed'.

  I have both AE and SOUL open and running.  In the menu for AE, I have the menu available dynamic links.  However, when you open the file .aep in SOUL I still get this error.

  -Dave

  Make sure that the SOUL and After Effects are updated to the latest version: SOUL CC 7.1 and after effects CC 12.1.  If there is a version mismatch it can lead to problems of dynamic links.

• A link problem, conflict between hyperlink and textframe

  Hi all

  I noticed erratic behavior after the creation of a hyperlink text in a textframe. Although the link seemed ok when previewing (both in Muse preview mode, as in a browser (Chrome) Preview), she had abruptly changed his State when I was about to click on it. After a few perplexed attempts, I noticed that the hyperlink is transformed into the 'pointed' state once the mouse is over the textframe containing the link and not the link itself. When I click on the link, the behavior is as expected, but moving out of the textframe and reintegrating gives the same effect. Somehow the textframe intercepts the mouseover, instead of the link event. Is there a way to disable this behavior and the target of the hyperlink instead? Thanks in advance. (I searched this question in the forum and had similar problems with menus, but not with executives of related, if I forgot an answer, my apologies in advance.

  Hello

  Please select the text frame and click the States window and let me know what you see. It would be better if you can share a screen like this,

  

  Kind regards

• LabWindows CVI and debugging dll MSVC ++

  We use a written LabWindows/CVI DLLS in the code for Teststand module. This DLL calls a DLL written in MSVC ++.  Is it possible to use the debugger of Labwindows/CVI debug this DLL MSVC ++ (if this DLL MSVC ++ is built with 'good' options)?  Or is possible only using the environment of development MSVC ++?

  Hello mkossmann,

  The CVI compiler generates different types of than MSVC debugging information.

  The debugger CVI doen't understand the debugging information generated by MSVC, so you cannot debug the dll compiled in MSVC.
