Question

When I attempt to run the following function,I got the following the error.Otherwise,When completing the process of function,I’m receiving the error.

 Debug error!

 The value of ESP was not properly saved across a function call. 
 This is usually a    result of calling a function declered with one calling 
 convention with a fonction pğointer declered with a different calling convention.

Code:

 typedef int(*FPROC)(char*,char*,char*,char*,char*,int,int);
 HINSTANCE hDllInstance;
 FPROC pmyfonk;
 hDllInstance = LoadLibrary(TEXT("mydll.dll"));
 if (hDllInstance==NULL) {MessageBox("...dll yok............");
 exit(0);
 }

 pmyfonk=(FPROC)GetProcAddress(hDllInstance,TEXT("myfonk"));
 pmyfonk(TEXT("xxx"),TEXT("xxy"),TEXT("xxz"),NULL,TEXT("xy"),1,1);//this function is working.But,I'm getting upper error.

 FreeLibrary(hDllInstance);

There is a mismatch between calling convention somewhere in your code. I’m new to windows programming so I don’t know much more but this is clearly what the error message tells.
