Development - Edit the Source Code
Introduction
FreeBar is written in Visual Basic (Classic). You need a version of Visual Basic 6.0 to compile the source code (the Standard Edition is sufficient). Also install the Visual Studio 6.0 Service Pack 6.
Registration of the Type Libraries
For developing FreeBar, you also have to register two Type Libaries. These are in the Folder TLBs of the FreeBar Source File Folder.
To register them, open the Project File FreeBar.vbp in Visual Basic. Then click on Project → Dependencies.
Two entries are important here: VB 5 - IShellLinkA Interface(ANSI) and IShellFolder Extended Type Library v1.2. If one of these entries begins with NOT FOUND, click on it and then click on Browse. Now select the appropriate TLB File for the entry from the Folder TLBs:
The TLB File for the entry VB 5 - IShellLinkA Interface(ANSI) is Shelllnk.tlb.
The TLB File for the entry IShellFolder Extended Type Library v1.2 is ISHF_Ex.tlb.
After the Registration of the Type Libraries, you should be able to compile the Project.
