Most resource editors support all the original Microsoft dialog controls. However newer controls like the toolbar and the status bar are not supported by any resource editor. Other controls like the rebar control are not well supported.
The resource compiler will correctly compile a resource script if the controls are manually added to the script. However, this requires some in-depth understanding of the resource script format.
C / C++ programmers typically add these controls to their dialogs using the CreateWindowEx() function. For ooDialog programmers it would be convenient if they could add these controls to their dialogs using methods with arguments they already understand.
