Cannot enter "design form" with contact-form, but with any other form
Posted on 2004-09-05
I have a very strange behavior of my local outlook. Let me start from the beginning.
I'm supporting an old VB6 programmed application which synchronizes outlook contacts with a central database and vice versa. The contacts for this synchronizing process are using a custom form. It uses the Outlook COM-Objects.
A few days ago, I had this application running and while moving a contact there was a runtime error.
Afterwards my outlook was extremly slow, but anything was working (about 50x slower than before).
After a restart of the system, the application could not access the contacts. An error "The form you selected could not be displayed. The operation failed" is displayed.
I deleted the form and cleared the forms-cache. After that I tried to reimport the form with the .oft file, but if I doubleclick on it, outlook freezes for about 45 seconds and nothing else happens. Sometimes there is a error message “The messaging interface has returned an unknown error. If the problem persists, restart Outlook”
I can open any contacts, which are using the original contact form.
I can select "Choose from" from the Tools-Menu and select the contact form. This works fine.
But I cannot use "Design form" from the Tools-Menu and select the Contact form. In this case, the designer window opens, is filled completly white, and contains for a few seconds the tabs "General / Details / Activities / Certificates / All fields" before they disappear after about 5 seconds, the window closes and the error "The form you selected could not be displayed. The operation failed" error occurs.
I uninstalled MS Office, reinstalled it and the same behavior is there. I installed SP2 for XP and SP1 for Office. After this the same problem is still there.
I created a new profile and the problem is still there.
I have no idea what the problem could be. It can't be a file of Office, at least not one in the MS Office directory, because all of them were deleted while reinstalling the package.
The only thing I can imagine is one of the systems dll's. But how to find the correct one. Or could it be the standard contact form? But I can open the contacts form with standard contacts Only not in the "design form" mode. The form designer should also not be the problem, because I can open any other form in it in the "design form" mode.
So actually I am lost. maybe one of you guys can help me. I don't want to reinstall the complete system if it is not absoletely necessary...
Thanks in Advance
