warning #2235 ??

[Vbxler]

Hi,

I use this function:

Code Select Expand

HINSTANCE hinstLib;

//------------------------------------------------------
// Laden der DLL
//------------------------------------------------------
int Load_DLL(char *szDLL)
{
//laden der DLL
hinstLib = LoadLibrary(szDLL);

//wenn laden erfolgreich, dann True
if (hinstLib != NULL) return 1;
}
I can compile, but get the message: warning #2235: Not all control paths return a value.
How can I prevent that?

Thank you very much.

Adding a return value for the case that hinstLib == NULL...

You only return a value when loading of the DLL was successful, if, not, the return value is undefined...

Thank you very much!

It's not so easy when you come from VB.

Thank you very much!

Kein Problem, gern geschehen! 

It's not so easy when you come from VB. 

If VB is compiling this without an error, it is even worse of a compiler as commonly  assumed.

It's a very general, logical programming error, leaving the function result undefined if the DLL load wasn't successful. This should generate at least a warning in all compilers...

And then C has a bad reputation for promoting bad programming practices...
