Of course you can still have resources in a 64 bit DLL... I have a couple of projects underway that are doing exactly that.

If your resource DLL is 32 bit and you have the source code, you can simply recompile it...

Even easier if you have it in a Pelles C project.  Click on Project in the main menu and on the submenu you will find an entry "Upgrade project to Win64"... click that and rebuild.

Do you have the source code?

If so, set it up in pelles C as a 64 bit DLL project and recompile... just like any other project.

Create the project... exit POIDE, put the source files in your project directory... then re-open POIDE and add the files to the project (right click the project in the tree pane...).

Then click BUILD...

Use linker option /NOENTRY if there isn't code at all.

In poide, just put that to Linker options field Library and object files:
Or in source file

Code: [Select]

#pragma comment(linker, "-noentry")
