Hi all,

I'm trying to use Interop to manipulate MS Project 2003 (MPP) files.

My problem is that MS Project reports that the files is already opened by another user (me!) and that I can open it only as read-only.

Obviously, I've tried to restart studio, then windows (xp) but with no effect. The file attribute for Readonly is cleared on the file.

Any suggestions for what I might try?!

Thanks,

Anders

Imports Microsoft.Office.Interop.MSProject ... Dim app As ApplicationClass = New ApplicationClass() app.Visible = False Dim success As Boolean = app.FileOpen(fullPath, False)
