Determining whether a control exists.
Hi,
Suppose I have a a control name like "pgf1.pag1.txtThis" and I want to know if it still exists on a particular open form. Is there an easy way to do this?
If it helps, the reason I have the control name is that I'm allowing the user to customize controls. 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.
Thanks.
