>I can't seem to get the HitTest method of a TreeView to work. I keep getting "Invalid type" errors on the numbers that I pass to it, and then I get "Array dimensions out of bounds" errors, on the method call itself. I've converted the X & Y coordinates in the MouseDown method to twips, and then call this.HitTest(lnX,lnY) from the MouseDown method. Any ideas?

Hi Fred,

Did you type the following code in the Load of your form?

=sys(2333, 0)
