Labwindows CVI problem

hello I´m trying to create an installer for an application created in a previous version of Labwindows CVI that a dont know becasuse i receive just de sources files, i´m working with 2010 version, the problem is that the application run perfect in debug mode but when i run it in release mode the application doesnt work, only the icon in the taskbar is showed but the graphic interface never appears, someone can help me with that
Solved!

I check all source files an there is no any #ifdef that could cause problems, the program is correct because is running in an old PC, what i am doing is trying to create an installer to change the program to a new PC, what i receive was just the folders project that are in that machine, but i can do work the program in my machine.

Labwindows/CVI SRQ PROBLEM

When I run out of Labwindows/CVI the software recognizes SRQ's. When I create
a standalone executable I no longer can detect SRQ's. Any Ideas?

How to set a DMA transfer type for PXIe-6536 in LabWindows/CVI?

I have a PXI chassis PXIe-1078 with a controller PXIe-8115 running under Windows 7. The digital output board is PXIe-6536.
I use a function DAQmxSetChanAttribute to set a property DAQmx_DO_DataXferMech to a value DAQmx_Val_DMA, since I want to use a direct memory access data transfer. This wokred well with a PCI-6534 board using the same LabWindows/CVI code before migrating it to the PXIe system.
Unfortunately, running this code on the PXIe system reports a DAQmx error -200452: "Specified property is not supported by the device or is not applicable to the task".
The task is created in the following simple way (the board name in MAX is 'Dev1'):
   DAQmxCreateTask ("digTask", &digitalTask);
   DAQmxCreateDOChan (digitalTask, "Dev1/port0:3", "DIG_CHANNELS", DAQmx_Val_ChanForAllLines);
   DAQmxSetChanAttribute (digitalTask, "", DAQmx_DO_DataXferMech, DAQmx_Val_DMA, 15);
How can I solve this problem? How is it possible to choose between different transfer types?
Thank you in advance for any hint!

Hi CavityQED,
The PCI-6534 is a "Digital I/O" board while the PXIe-6536 is a "High Speed Digital I/O" board, that's why they don't have the same properties.
By the way you can use DMA transfer with this method :

How to get bar graph in word in labwindow/CVI ?

how to get bar graph in word in labwindow/CVI ?

ashwinic9,
spawning your question over more and more threads (the present one, this one and this other one) won't give you a faster answer; instead, it will irritate forum users!
Especially if you have at your disposal a fast way to perform a test. I pointed you some days ago to word report example, that writes a table to a word document: did you tried changing the graph into a bar graph and generating the report? I have done it for you and the result is OK, as you can see in the attached document.
Now, since the example works well, there must be something in your particular situation that prevents the graph to be shown; that is: you must add some more data on your actual problem and maybe a small example that exposes the problem.
But please: keep active only this discussion and let the other threads die!
Proud to use LW/CVI from 3.1 on.

How does the URL of DataSocket constitute?And how to use it in LabWindows/CVI ?

Hi ！
There's a problem puzzled me some days.How does the URL of DataSocket constitute ? And how to use it in LabWindow/CVI ?
For example.I have downloaded a code in http://zone.ni.com/devzone/cda/epd/p/id/3787.I want to make it work properly.So I configure my DataSocket Server Manger according to the URL of this statement.
DS_Open ("dstp://weather.natinst.com/weather/current",
DSConst_ReadAutoUpdate, DSCurrentCallback, NULL,
&dsCurrentHandle);
My DateSockket Server Manger is configured as:
However,it could not work properly when I debug it.
There's a introduction at the top of the code."You may need to replace the references to weather.natinst.com to 130.164.140.10 if the DNS isn't working properly."So,I modified the statement into
DS_Open ("dstp://130.164.140.10/weather/current",
DSConst_ReadAutoUpdate, DSCurrentCallback, NULL,
&dsCurrentHandle);
but,it did work properly.
We want to communicate with other computers via the URL of DataSocket in LabWindows/CVI.Whereas,how could we make it ia the URL ?
If anyone could help me solve this problem,I would appreciate it very much !
Best regards.

Hi !
Thank you very much for your reply! I will accept your advice.
Besides,I have another question.If I want to visit other computers or other websites，how does the URL of DataSocket I constitute ? Does the URL has any relation with the DataSocket Server Manger ？If does,how to configure the DataSocket Server Manager to let them connected.If they have no relation,how to use the DataSocket Server Manger ?
After all,I want to know how to use it in LabWinows/CVI ？
Thank you very much !
Best regards!

LabWindows/CVI 2013 SP2 stops working when I try to open a file using the project file menu.

I have windows 7 on my system and sometime late last year I starrted getting a Windows dialog telling me that LabWindows/CVI has stopped working when I try to open a file from the project file menu. I also get an error when I run a project debug mode and use a selectFilePopup in the code. The error says, "The program has suspended execution at address 0x75D5025E. No source line information is available." I've tried removing and reinstalling CVI to no avail. Any suggestions?

Constantin,
Thank you for your response. I've attached screnshots showing the version details for kernal32.dll and ntdll.dll. I also looked at the updates to see which might have been installed when the problem started. Unfortunately there are 15-20 updates every month. I didn't take note of when the error started to occur. At first it only affected my ability to open files from within the project (i.e. file->open->Source, etc). Then I went back to modify a project that had a SelectFilePopup and found that that wouldn't work either.

The application uninstaller ,created with Labwindows CVI, doesn´t work after upgrading to 2010 version

Hi,
I have been working with Labwindows CVI 2009 with no problem but after upgrading to 2010 version I have the following problem:
When i´m going to execute the unistaller, either from Windows Control Panel or directly from the uninst.exe icon, it doesn´t work. The PC thinks a few seconds and does nothing, and it happens with all the applications I build with Labwindows CVi 2010.

Hello -
Are you installing these distributions on a non-English operating system? If so, the first thing to try would be the workaround listed on this known issue.
The known issue only lists Italian OSs as the troublesome OS, but it could actually happen on many different non-English OSs. I will update the text accordingly the next time I update the known issues list.

Is there a way to do multithreading in LabWindows CVI 5.0(Windows95)?

Because I would like to do several functions in the same .c file, in the same time. This morning, I asked this question:
Is there a way to do multithreading in LabWindows CVI 5.0(Windows95)?
Because I would like to do several functions in the same .c file, in the same time.
You answer me, and you give me some files, some documents. In this documents, there are these routes:
cvi\samples\utility\threading
cvi\apps\dagmthread
but I have not these files with the 5.0 version.
How can I do?
A French guy.

Hey my French friend. I'd say something cute in French but I don't know any so I'll kindly refrain.
I just wanted to echo what Chris said. There are some sweet functions in 5.5 that really make it easy. I tried running my thread app that I made under 5.5 on 5.0 and got all kinds of problems. Mostly because none of the helper functions I wanted to use are in 5.0. Makes sense right? Anyway, 5.5 is a worthy upgrade. I wanted to make sure you didn't think Mr. Matthews was just making a sales pitch.
Let me know if you want some example code for threading under 5.5. ([email protected])

Using DLLs created with LabWindows/CVI 8.0.0 in LabWindows/CVI 8.0.1

Hi,
I have created a project containing some methods with LabWindows/CVI 8.0.0 and then build the project and generated the DLL and LIB files. These DLL and LIB files are working fine in another projects created in LabWindows/CVI 8.0.0 (even on another machines).
But when I use these DLL and LIB files in a project created with LabWindows/CVI 8.0.1 on another machine and try to call the methods of these files, the following error occurs: -
"The program has caused a 'Unknown' fault at 001B:7C812AFB"
Is this error occurs due to ther version mismatch or there is some other problem?
Please help me to resolve this issue.
Thanks,

Labwindows CVI 2010 and GetProcessAddress()

I am using Labwindows CVI 2010 v10.0.1 after upgrading from version CVI 2010 v10.0.0. After the upgrade, I have a compile error from a statement that compiles just fine in the previous version. The error is:
"Operands of = have illegal types 'pointer to __stdcall int function(int,pointer to char,pointer to char,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, char y[], char z[], char *m, int g, char A[], char B[]);
(function names and parameters have been changed for simplicity)
As I said, this line compiles just fine in 10.0.0, but not in 10.0.1. Is there a specific update to the compiler that will cause this error? What can be done to fix this?
Thank you very much for your time and help.
Solved!
Go to Solution.

You're correct. This was caused by a change in CVI Windows SDK headers that took place in version 2010 SP1. The change was associated with bug fix #275934. Unfortunately, this bug fix introduced this undesirable side effect of requiring a cast for any function that returns a FARPROC function poinrter (such as GetProcAddress). Upon further reflection, this side effect is unacceptable, and needs to be corrected in the next release. This is being tracked internally with bug ID #336341.
I'm really sorry for this inconvenience. Until the problem is resolved, using the typedef & cast solution that you already implemented is a valid workaround.
An alternative workaround, in case you're worried about other projects, or other functions, where this error might also pop up, is to edit CVI2010\sdk\include\windef.h and replace the following FARPROC definitions (in lines 226 and 230, respectively):
typedef INT_PTR (FAR WINAPI *FARPROC)(void);
typedef int (FAR WINAPI *FARPROC)(void);
with:
typedef INT_PTR (FAR WINAPI *FARPROC)();
typedef int (FAR WINAPI *FARPROC)();
Doing this will avoid the problem throughout a given installation of CVI.

Example LabWindows/CVI code for NI4351

Hi,
I'm using an NI4351 PCI DAQ card with the Ni435x
driver and LabWindows/CVI v5.5 (on Windows 98) to measure temperature
and voltage levels. Are there any simple tested code examples that I
could download, which use the NI435x driver function
NI435X_Check_and_Read(), called from an asynchronous timer for
continous scan? There are no problems when I use MAX (so hardware
problem is ruled out), but my code yields
occasional random temperature reading errors (looks like data
corruption to me). The NI435x_ functions return no errors. Can I use
lower level C driver functions instead of NI435X_Check(), NI435X_Read(), or NI435X_Check_and_Read()?
What does MAX use behind the scene? Of course, the MAX setup only scans
the one channel, so maybe this is why it works correctly. I have to
scan one temperature channel and six voltage channels though.
Many thanks,
John.

Humphreyy,
thanks for the tip. I tried it but it did not work, the same errors were present. Are there any other suggestions. I have racked my brain to figure out why this is happening and have come up with nothing. I am also getting a "Warning" message concerning the "KsMedia.h" file that says "Warning: Excess characters in multibyte character literal ignored." The warnings trace back to the "typedef enum" section of that file. Could that be causing a ripple effect that produces the error I am seeing in the other header files I mentioned??
I could really use your help and any more help that is available. I really don't want to use Visual C++, because this software is going to get more sophisticated and is to be used in NASA Langley's VISTAS simulator, an environment taylor made for National Instruments software.

Dynamic memory is corrupt (Labwindows/cvi 2010)

I have a multi threaded application....where I have a buffers allocated ineternally in the threads,,...A user interface is present to abort the therad execution.
Here is the code in one of the threads (NOTE: status is set by a user button to EXIT the program):
int EthernetDataStructureThread (void *functionData)
    CmtSetCurrentThreadPriority (2);
    EthernetData GetData={0}, *data=NULL;
    data = &GetData;
    /* Use a buffer to read the data from the queue which is coming from TCP read with fresh data */
    const void *BufferEth;
    int BytesRead=0;
    int BytesWritten=0;
    char ReadErrorMessage[256];
    BOOL bitset = FALSE;
    if ( (BufferEth = (EthernetData*)malloc(EthernetDataSize)) != NULL)
        while ( !status )
            BytesRead = CmtReadTSQData (Queue_TCPRead_EthernetData, BufferEth, EthernetDataSize, TSQ_INFINITE_TIMEOUT, 0);
            memcpy (data, BufferEth, EthernetDataSize);
            /* Empty the queue so that we don't have data in next time. */
            CmtFlushTSQ (Queue_TCPRead_EthernetData, TSQ_FLUSH_ALL, NULL);
            //Pass on the data to the Main thread
            BytesWritten = CmtWriteTSQData (Queue_EthernetData_Main, BufferEth , EthernetDataSize, 1, NULL);
            if ( BytesWritten != EthernetDataSize)
                 free(BufferEth);
                BufferEth = NULL;
                exit(0);
            Delay(0.02);
        if (status && !bitset)
            free(BufferEth);
            BufferEth = NULL;
            bitset = TRUE;
    return 0;
My problem is: free(BuffEth) always says Dynamic Memory is corrupt......When I put a breakpoint and keep seeing the resource tracking window, I can see it getting executed fine as the resource tracking window greys out the memory block....but then suddenly free wants to exceute again...and causes the "dynamic memory is corrupt" error.
I am using LABWINDOWS /CVI 2010 SP1 in WinXP.
Please help me ASAP....very much appreciated.

Thank you for your reply Jackie.
I am calling Free only once...there is an If condition there.
See the attched video for my problem...Free frees the memory block (see the greyed out portion in resource tracking window but still the statement controls remains there and free executes again, throwing error).
Do you think it is some sort of bug in LABWINDOWS.

Permission Denied Error when calling Matlab script from LabWindows/CVI

Hello,
I am reading in data from a DAQ and am writing it to a .csv file in LabWindows/CVI. I am then sending this data to Matlab to be filtered. I would like the filtered data to be accessed by LabWindows/CVI so that I can display it as a strip chart. I have gotten everything to work except the writing to a file in a Matlab script that is called from LabWindows/CVI. I am basically using the shipped example in found in the activex demo. (http://zone.ni.com/devzone/cda/epd/p/id/2994). I select the script that I want to run and each time it tries to open a file with write permissions I get a "Permission Denied" error. This occurs when using fopen() in Matlab. I have also tried using csvwrite() as well as dlmwrite(). Each one gives me a similar error. The script currently does not try to do any data processing. It just opens the file, if it is successful it then prints "hello" and then closes it. The script works well when it is run in Matlab, just not when it is called in LabWindows/CVI. Below is the script. Any thoughts, comments or suggestions are greatly appreciated. I am also open to using other approaches for sending data between Matlab and LabWindows/CVI. Thanks in advance!!
fclose('all');
[file, errmsg] = fopen('out.txt', 'w');
if(file<0)
   disp(errmsg)
else
   fprintf(file, 'hello');
   fclose('all');
end;
[file, errmsg] = fopen('out.txt', 'w');
if(file<0)
disp(errmsg)
else
fprintf(file, 'hello');
fclose('all');
end;

I am using Windows 7. I am running CVI as an administrator and was able to get rid of the "Permission Denied" error by going into the User Account Controls in windows and changing it to "Never Notify". However, this did not fix the problem of Matlab not being able to write to a file when the script is run from CVI. In the Matlab code below, It now gets in to the "else", suggesting that fopen() returns a good file handle. After getting in to the else statement, it will not actually write to the file, nor does it create it. However, I can make changes to the plot settings and those appear. Everything is functional when run from Matlab but when run from CVI, things get screwy with opening the file for writing. It handles the read well. It seems like there would have to be some file permission errors but, in the CVI program, I open and write to the file "in.csv". Any help is greatly appreciated.
clear;
fclose('all');
t = zeros(1000);
t = csvread('in.csv');
for i=1:1000
   t(i) = t(i)*4;
end;
[file, errmsg] = fopen('out.txt', 'w');
if(file<0)
   disp(errmsg)
else
   fprintf(file, 'goodbye');
   for i=1:1000
   %t(i) = t(i)*3;
   fprintf(file, '%f,', t(i));
   end;
   fclose(file);
   plot(t/3, t);
   ylabel('t');
   xlabel('Time (s)');
   title('Is this really working?!?');
end;
Thanks,
Chris
