Anyone know about this problem.?

I am using VS 2008 and QT 4.5.0

Answer 1

Are you sure that your *.ui file are in the qt4 format and not in the qt3 format ? If there have been created with qt3, ui.exe can convert them to qt4 !

Another reason could be the version of the qt-integration tool for visual studio 2008, Do you have the last version ? Can you open the *-ui file with Qt Designer ?

Answer 2

I had the same symptoms, and the solution was to remove the top line of the ui file (once open with a text editor)

Surprising that Qt does not support well formed xml...
