1. Extract the resources from the .EXE file using a resource file editor.
   I have used ResEdit (freeware) for examining resources in EXE files. IIRC, it can also extract resources from an EXE/DLL.
2. Convert any VB6-specific elements to generic Windows versions
   Each dialog etc. specifies its "class" type, which affects how it is displayed. This includes the DLL that must be loaded in order to display it. Convert any VB6-specific names to the generic equivalent (e.g. "VB6button" should be renamed "button", "VB6dialog" should be renamed "dialog", etc.)
3. EDIT: Some ActiveX controls may have no generic control that can replace them. In this case, you must decide whether to use a class library that supplies the missing functionality, or eliminate them from the file.
4. Recompile the RC file using the Visual Studio resource editor.

So, I used the namespace with curly braces{} suggested somewhere on the net
