So Close..

[jamez05]

I have an executable that needs to call an external DLL. This DLL accepts a string and opens up a new window.

If I call it in VB, the window opens fine. I get the CPP program to call it, but the window closes right away.
I'm missing something, but not sure what. Below is the code:

*/
main()
{
    
     /* get handle to dll */
     HINSTANCE hGetProcIDDLL = LoadLibrary("C:\\WINDOWS\\system32\\Chem2D.dll");

     /* get pointer to the function in the dll*/
     FARPROC lpfnGetProcessID = GetProcAddress(HMODULE(hGetProcIDDLL), "Show2D");

     /* Define the Function in the DLL for reuse. This is just prototyping
        the dll's function. A mock of it. Use "stdcall" for maximum compatibility.
 */   
     typedef int (__stdcall * pICFUNC)(char*);

     pICFUNC MyFunction;
     MyFunction = pICFUNC(lpfnGetProcessID);


	 /* The actual call to the function contained in the dll */ 
     int intMyReturnVal = MyFunction("CCCCC");

     /* Release the Dll */
     FreeLibrary(hGetProcIDDLL);

     /* The return val from the dll */
	
	 return intMyReturnVal;
	 
	 cin.get();
}

If your intention was for the cin.get(); to wait until you press enter before closing the cmd window you'll need to move it before you return from main().
