Thread: Compiled App as release - won't run - as debug runs

Could someone give me a few suggestions here:

I am using Visual C++ 6 Enterprise. I have written a small program that plays a wave file...

Application Type: Win32 Application (not console)
Using MFC: No

Program Description:

The program opens a data file and reads the first line to get the path to the wave file, then plays it using PlaySound. If either the data file or wave file can't be found, it displays a messagebox and then exits.

When compiled as "Debug", it works fine...and if I rename the data file, the messagebox appears and then the program closes...

I switch my "active build configuration" to "Release", compile and when I run it, it says it can't find the configuration file (yes, I named it back to the original). Also, instead of the messagebox having the message "Can't find data file", it is just filled with a bunch of crap and the title is the path to my executable, not the title I told it to display...

So I'm curious why this happened. I did not change any code from "Debug" to "Release".

Any ideas?

I put a copy of the config file in both folders. But the only executable that works is the one in the debug folder.

The wierdest part is as I mentioned, there is absolutely nothing different about the two .EXEs (except for the debug info that increases the size of the debug build).

I wonder if it may have to do with some of the linker switches. I didn't change them from the default and I know the debug build has different switches than the release build... just because a compile doesn't report any errors doesn't mean it worked...

If it would make it easier, I can post the code ina couple hours... I don't have it with me here at work.

Ok. What would I look for in the debugger?

I can't debug the release version because it doesn't contain any debugging information.

And since the debug version works, I wouldn't see anything wrong in there.

there could be quite a few reasons. the things to focus on would be bounds checking, initialising your structures/arrays/pointers to zero, and cleaning up memory properly.

if you are still stuck, post your code and i'll check it out for ya.
