>>>>>Sorry I am not getting it. Again, in my case - now - the popup form is MODELESS. As soon as the code in this, POPUP MODELESS form, calls .hide(), the method DEACTIVATE is fired. And therefore, the .tag is gone. That is, as soon as hide() fires, the code (in the debugger) goes to the READ EVENTS line.

>>>Thank you for clarifying what Deactivate method does. But somehow it does not work in my form.
>>>As soon as I click on any button in the popup form, the method in this button fires. The method is simply the following:
>>>

>>>thisform.tag = '1'
>>>thisform.hide()
>>>

>>>The in the Calling method, after oPopupform.show() the code should evaluate the value in the oPopupform.tag.
>>>But the code never moves to the next line, after the oPopupform.show(). The code goes to READ EVENS.
>>
>>This is normal for a MODELESS form.
>>In my example above, the code is ended in an instant. The form survives only because it is bound to a public var. Code does not wait for the form, that's the idea of modeless. It will wait for a MODAL form, in short MODAL means. Do nothing then me.
>>
>>To get a result from a modeless form, you must give the information to the caller. IOW, the form must active store the information, or you need eventbinding to catch the hiding of the form.

>I get it. So assigning a value to the .tag of the popup form does nothing. I will see what I can do.
>Thank you!

If you need ideas / examples how to do this, let me know.
