I think I got it working:
From VC2005 there's a function called AddResourceInstance() to chain DLLs. However am still using VC6 so this function doesn't exist.
So I just copied some code from a DLL project. The DLL main file contains these lines:
Code:
static AFX_EXTENSION_MODULE NEAR extensionDLL = { NULL, NULL };
DllMain(HINSTANCE hInstance, DWORD dwReason, LPVOID lpReserved)
{
AfxInitExtensionModule(extensionDLL, hInstance);
new CDynLinkLibrary(extensionDLL);
}
This dynamically loads the DLL. If we put some of this code into the EXE project like so:
Code:
HINSTANCE hDll2 = LoadLibrary(szFilename2);
AfxInitExtensionModule(extensionDLL,hDll2);
new CDynLinkLibrary(extensionDLL);
After the AfxSetResourceHandle(hDll); //setting satellite DLL overriding EXE resources
Originally, the EXE would be the resource container, but AfxSetResourceHandle(satelliteDLL) will set loaded DLL as default resource container, overriding the EXE like.
We use the above extension DLL to chain (add-on) another resource DLL.
The only issues now is freeing the library/memory..
