Hi Mike

You could also conditionally add a validation object to the textbox. This would be done at runtime. Debugging Execscript can be difficult. Classes already in your exe are not directly available to exescripts called from that exe.

What I did so far was create a custom property for the textbox class named ValidateCode. I put a string of VFP commands in it based on the specific column I'm in and in the textbox class Valid() method, I have:

>IF !EMPTY(this.ValidateCode)
>   EXECSCRIPT(this.ValidateCode)
>ENDIF
