VisualStudio.Net Add-in written in Delphi, part 2

Ok, adding a new tool window wasn't hard at all, actually it's quite simple.

Just create an ActiveX form, get it's GUID from the type library window View -> Type Library and call the following functions:
myToolWindow = DTE(Application).Windows.CreateToolWindow(AddInInstance, 'your_library.activex_form', 'Some Title', '{THE GUID}', dummyIDsipatch);
The form is just like any other form in Delphi, you might want to set the form's AxBorderStyle to efbNone.

One ting, when creating an activex form Delphi automatically changes the target extention to ocx, I didn't like that and changed it back to the normal dll. Also, don't forget to register the "ActiveX Server" when you added a new COM object, otherwise the GUID won't be registered in the registry.
