replacing the default icons.dll

[PaulinCA]

I have a C3PO that adds a toolbar button and works perfectly when I click on it. This is done with the using the default icons.dll file.

However, when I try to create a new file with Visual Studio 2008, it doesn't show up. I have extracted the files from the default icons.dll and used those same exact icons and bitmap to try and create something new. Everytime I do that, it never shows up in the toolbar. This is a stupid question but can somebody give me a starting point to creating either a new dll or exe that can be used with the C3PO API in VS2008? I read somewhere that it can be in an exe or dll file and I've tried just about every kind of those file types in VS2008 and nothing works.

Thanks in advance.
