Hi, Jim!

Are you really use type function for this? As far as I know, type function works 6 times slower than PEMSTATUS...

When a form opens I look through a table to see if any of there any customized controls for this form. If so, I use the saved name to create a control object and then customize away. However, I'd like to make sure the control actually exists without having to parse out the name and doing a PEMSTATUS on each level. Being a VFP newbie, I can't figure out a better way.

The professional level of programmer could be determined by level of stupidity of his/her bugs

It is not appropriate to say that question is "foolish". There could be only foolish answers. Everybody passed period of time when knows nothing about something.
