Tony,

You can check TYPE("Thisform.pgf1.pag1.txtThis.Name") = "C" If the data type of the Name property is C then it exists, if not it does not exist.

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.
