Hello Armin

but this way, the control cannot get the focus!? I think the only way to suppress VFP's default behaviour would be, not setting Format to "K" and setting SelectOnEntry=.F. Or am I totally on the wrong way?

Sorry, but you are mistaken here. The default VFP behavior runs. It just runs beore the cutom code that sets the highlighting.

Copy and past the code into the GotFocus() of a textbox and see for yourself < s >.
