Visual C++ cgi fails with exception error only when running as cgi

Hello,

I have written a custom Visual C++ cgi currently running under Apache in Windows 2000 that takes some form data and puts it into an access database. If I double click the executable file from the desktop and enter some data into it, it works fine. However, if the program is launched via the web server hit connecting to the database causes an unhandled exception error.

Does anyone have any experience with this? If so I can email you the visual C++ project. This is very frustrating as the program works fine but I wonder if when launched as a CGI from the web server maybe the program needs  to do something special to initialize the standard ODBC32.lib functions.

Thank you.

My direct email is pinskerj@satx.rr.com if you can answer this question.

Is your .mdb file located under the wwwroot directory of the webserver? If not, try to move it there.

I will try this. Why would that even matter though? Thanks.

No this did not work at all. Sorry. Still no idea why I can't seem to run it as a CGI correctly.

It matters because of access permissions. Did you both move the file and update the file location in the odbc config?

Yes, that did not help. However, I searched DejaNews for a long time and found the answer. Many people have had this problem with Apache. The trick is follow the following directions to make Apache run as a process not in the background, then everything works great:

I'm excited to announce that I solved the problem. I often started Apachefrom Start | Programs | Apache Web Server | Apache Server. That was theproblem. Now I go to MSDOS Prompt at c:\apache and type "apache" or just open the bin folder and double click it, then my script runs great...

Thanks for your help. I will accept your last comment as the answer.
