As you had said in your previous post, you don't have DevStudio installed, which means it probably don't have all the required libraries installed (MFC42.DLL and MSVCRT.DLL if you are using MFC) installed. To solve your problem, copy all the required DLLs to that system or statically link all the required libraries.

There is a program shipped with VC 6 calles depends.exe (in the Visual Studio\Common\Tools) directory. You can use this to see all the dlls that your ocx depends on. And then you must install them on the destination computer (but dont overwrite newer versions on the destination computer.)

Run this test program in Debug mode to find out why your dll is failing. It will probably give you a message box that a DLL isn't in the path. Then you can copy the DLL and party on!


#include <windows.h>

void main()
{

HANDLE h = ::LoadLibrary("C:\\Temp\\MyDLL.Dll");

LPVOID lpMsgBuf;
::FormatMessage(FORMAT_MESSAGE_ALLOCATE_BUFFER | FORMAT_MESSAGE_FROM_SYSTEM,
NULL,
GetLastError(),
MAKELANGID(LANG_NEUTRAL,SUBLANG_DEFAULT),
(LPTSTR) &lpMsgBuf,
0,
NULL );

::MessageBox( NULL, (const char*)lpMsgBuf, "GetLastError", MB_OK | MB_ICONINFORMATION );
::LocalFree( lpMsgBuf );

if( h )
::FreeLibrary(h);

}

If you are using mfc then you have to ship mfc dlls with your control. Get from redist directory of visual studio or VC. There are redistributable dlls. You have to ship mfc42.dll, msvcrt.dll ( mfc42d.dll if debug mode ) and make sure your dlls are same version as VC you are using.
