Hi Chang!

I use the following strategy: I make an object reference variable (usually a property of application object or global variable) to the form, and on issuing the form I check wether if it exists or doesnot.

if type("goApplication.frmMyForm.name")="C"
** form exist
goApplication.frmMyForm.Show()
else
do form myform name goApplication.frmMyForm linked
endif
