So I compiled a C library in visual studio 2005 and everything was fine. However, on certain operating systems (windows server 2003) for instance, When my visual basic 6 application tries to call the dll, it pops up error saying that the library was not found - and yes it is there. I tried countless things to fix it such as moving the library to the system32 folder, installing all possible run time files i could think of, patching both the vs 2005 and vb6 compilers, etc... but it still doesn't work.  Again note that this error doesn't occur all the time, only on a few select operating systems and/or computers. Did anyone ever run into something like this before?

well i decided to recompile the library in visual studio 6 and everything works.

still, weird how incompatible vs 2005 is.

Almost certainly you have a missing dependency.

I installed all the possible ones i could think of. I guess i must be missing something though. oh well.

I ran into a problem similar to this a while back as well.  What happened was that when I executed my VB code (not running a compiled version), it crashed.  But when I actually compiled my VB and made an executable file and ran it, it worked.  One of the many reasons I left VB....

lol without compiling i get Bad DLL Calling Convention error.. WITH compiling, i got the file not found error. Yeah I don't code much in VB anymore, but i'm not gonna rewrite some of my old stuff in something better.

the debugger does not run the application out of the same directory that the default compiled executables are placed. this is a possible reason for frostwraith and shadow's troubles. if you leave a language because of issues like this, they're likely to follow you to your new language.
