I get this error message: Unable to display "Options" page. This page will remain visible, but is not available.

Delphi 5 (not 2005!), most recent Add-in express version, Outlook version 2003, (11.6568.6568) SP2.

I can't find the cause of this error. Any idea where I should start looking?
With kind regards,

Hi Wim,

I can't tell you for sure at the moment where the cause may be. Did you change your add-in's type library? Can you send me your project for testing?

Considering the size of the whole project and the fact that it needs additional hardware and software to run, I just can't send you the project.

I also have the old sourcecode since I just copied everything to a new folder to work from. This code still works as expected. But concerning the type library, what has changed is the name since I've renamed the project. After renaming the project back to it's old name and copying back the old type library, it just seems to work again.

The Windows COM mechanism... Definitely NOT something I like. Powerful, yes. But also too easy to make hard-to-spot errors.

Hi Wim,

If you change the project name, you need to change the first parameter (the ProgID of your options page) in the OptionsPagesAdd method.

procedure TAddInModule.OptionsPagesAdd(...);
begin
Pages.Add(OptionsPageProgID, Title);
end;
