Initiates a dialog resource.
ExecuteDlgInit will use resources bound to the executing module, or resources from other sources. To accomplish this, ExecuteDlgInit finds a resource handle by calling AfxFindResourceHandle. If your MFC application does not use the shared DLL (MFCx0[U][D].DLL), AfxFindResourceHandle calls AfxGetResourceHandle, which returns the current resource handle for the executable. If your MFC application that uses MFCx0[U][D].DLL, AfxFindResourceHandle traverses the CDynLinkLibrary object list of shared and extension DLLs looking for the correct resource handle.
