Are you sure there is not an easier way to do
that?
There should be a Text property.

Wouldn't it be simpler to use a line like this:

MessageBox.Show(StatusBar1.Panels(0).Text)

??
 
thanks for your help,

I guess I didn't make it clear, this is for my program to get the text in a
statusbar from
another program.

thanks

Chris,

Click to expand...

For the application currently executing yes, but not for other
applications...
