Linking...
maintoolbar.obj : error LNK2001: unresolved external symbol __imp__InitCommonControls@0
Debug/toolbar.exe : fatal error LNK1120: 1 unresolved externals
Error executing link.exe.

toolbar.exe - 2 error(s), 0 warning(s)

You need to add comctl32.lib to your project.

Tip: whenever you use a Microsoft API and you get a link error, look it up in MSDN, usually they put the required lib file in the API help page.

AGAIN, as pingpong mentioned...

You need to add comctl32.lib to your project.

If you are using VC++, then go: Project - Settings - 'Link' tab - category 'General' or 'Input' - in the box called 'Object/library modules:' add the "comctl32.lib" and separate it from others with a blank. Click OK. Rebuild.

In case you have some other compiler - check its manual on how to add a library to link with.
