exe encounter problem

analog — Mon, 19 Jul 2004 19:47:22 GMT

Hi,

I get the following error when I try to run my .exe files. "some program.exe has encountered a problem and needs to close. We are sorry for the inconvenience." I noticed in one exe, I get this problem after I successfully ran the application, then close the application and the error message will pop up. On two other applications, this error appears when the exe just started running. If I just run the vi's of these application, I get no problem at all, but I need for the executable program to work though. Help, please!

Thanks.

When building the exe. are you sure you are including all of the files.It sounds to me like something is missing from the build.

trying to help.

Yea, all the files are included. One of the applications is working perfectly and display right result until you hit the exit button. Then the error message appears.

Do you have an actual exit button that you created or are you using the x in the top. also if it is not to much trouble could you post some code.

Also, this text file appcomptat.txt was generated with the error:

I just hit the x at the top. I cannot post the code because it's very big, sorry! But I tried to make application out of only part of the code and it works ok.

Hi analog,

If you are closing the application by using the "X" button at the top right corner, you are probably getting this error because your application is not cleaning itself up correctly. You shouldn't be closing the app with that X. Rather, have a Stop button or Exit button to quit the application. This way, it gives the app the opportunity to clean up memory space it used and deallocate as necessary. I have a feeling that your error may be related to this.

Hi,
I have narrowed my program down and found that this error is generated when I tried to call a dll. I have included the dll and some code. I have use this code with windows 2000 before and with this dll and everything is hunky dory, but now that I put Windows XP OS on my computer, the exe is the only thing causing a problem, the VI is still working fine. I have another exe file which I created to parse an xml file and that exe doesn't give me any error upon closing, so I am thinking that the dll is a problem. If anyone has windows 2000, can you use my code to build an exe and then post it here so maybe I can test to see if there is any difference? Thanks. http://exchange.ni.com/servlet/ProcessRequest?RHIVEID=101&RPAGEID=137&HOID=506500000005000000

I still don't understand your Stop button or Exit button concept though. My program stops completely and you can re-run it with the RUN button at the top, doesn't that mean that the program has stopped? I don't understand how I would implement this STOP button idea without using another loop outside or an event structure. But either way, it would seem like extra unneccesary code, right?

Yes, pressing the X button stops the program and you can rerun it, but doing that doesn't necessarily mean it cleans up all of the memory allocation that it did. By using a stop button (which would be just a large while loop around your whole block diagram), you allow labview time to deallocate memory it used for this application, rather than having a forced sudden stop. also, your dll may be doing some allocation of memory so that when you close your program, that memory the dll accessed may not have been deallocated as well.

Hi,
I use a stop button now but it still doesn't take care of the error message. It still pops up.
Thanks for trying to help.

Has anything changed other than the OS? Do you have everything for the program that that was installed on Win2000 installed on WinXP? Is there any differences in software when you upgraded? Did you do a fresh install of XP, or did you overwrite the existing 2000 OS? Sorry for the barrage of questions, but I figured it wouldn't hurt to know some more about your system since hypothetically that change affected the program.

Hi,
It's a completely new CPU with Windows XP, we took the hard drive out of the CPU with Windows 2000 and then copy that memory to the hard drive of the new computer. Then reinstall LabView on the new computer. I am sorry if I said just a new operating system, it's actually a new computer.
Thanks.

Have you tried using any other application to call the dll and see if the same error pops up? Then we can really narrow the issue down to the dll if it happens with any other app that calls it. It seems as though you've done a pretty good debugging job on it though, outside of accessing the actual code of the dll. I would like to see if the DLL just doesn't like to run on an XP machine or if it is trying to access anything that is specific to 2000.

Hi,
I don't know what other application to use to call this dll though. But this dll was recompiled from a .exe program written in VB. The .exe program is working fine. Have you tried running the code that I posted?
Thanks.

You wouldn't be now using the "stop button" on the LabVIEW Tool-bar would you? This is basically the same as "x"-ing the program.

No, I am not talking about the "stop button" on the tool bar.

Hi,

I registered your 3 dlls (SAX2.dll, deplevaldll.dll, and depldevdriver.dll) using the registration utility you linked to on my XP machine. Then I ran test.exe, as well as test.vi, but both came up with errors. The errors i received were:

Run time error 91:
Object variable or With block variable not set

and

Run time error 440:
Automation error

Are these the errors you were getting?

No. I got this error when I close the exe "test.exe has encountered an error and needs to close." You might need to copy these two dll as well into the windows directory or the directory that you are running the VI. Thanks for trying 😛

Hi,

I still keep getting the same error and cannot run the app. I have registered deplevaldll.dll, depldevdriver.dll, and sax2.dll using the reg utility, and then copied dxusb10.dll and drvx40.dll to my system32 directory, as well has kept a copy in the same directory as the executable. No luck. Is there any other file that I need to run? Thanks!

You will also need to register this dll, sorry I forgot to include it. But it might be easier for you to just go on the website and download the exe, that should put all the dll in for you except for deplevaldll.dll, so make sure you make a copy of it then place it in the installation folder, and register it. But I have attached the other dll that you need. And the link for the setup.exe in case you just want to install the program is http://www.analog.com/Analog_Root/productPage/productHome/0,2121,generic%253DAD9882%2526level4%253D%25252D1%2526Language%253DEnglish%2526level1%253D117%2526level2%253D%25252D1%2526level3%253D%25252D1%2526metaId%2
53D1098%2526resourceWebLawID%253D356,00.html click on "AD988x Evaluation Tools Software Program". But then you will still need to register the dll and copy the other two dll's into the window's directory if you decide to do installation. Thanks again for trying.
