Console-mode (VB)

I have created a class-module for easier access.
When i create the console it pops up, but when i print something it displays very wierd. It tent to vary if i change the lenght of the string but not if i change the content of it (same lenght).
I think it also changes if the handle changes.

You can read the about it here.
Can someome send me a working example?

Please help!

Hope this helps, and thanks for Scott Lloyd.

Don't worry, that was from this site anyways.

Thanx!
