>>>>I have a Date Control that I use everywhere in the application. The control is a container with a textbox and a button. When user clicks on the button the Calendar pops up for user to select a date (I am sure everybody has these controls). The Calendar shows right below the container, based on the container (Date Control) position. This works everywhere but on the form that has Auto Centered set to .T. In this case the Calendar pops up in the position where the form would be opened if not for the Auto Centered.

>>>One thing I've done in the past when I want something to pop up at a fixed position relative to something else, is to pass the desired coordinates to the invoking call. Suppose you want the top left of the calendar to always appear at the bottom left corner of the container (i.e. the Parent of the button):
>>>

>>>* Button.Click()
>>>ShowCalendar( This.Parent.Left+thisform.Left, This.Parent.Top + This.Parent.Height +  thisform.top )
>>>
>>>* ShowCalendar()
>>>* Create the object
>>>* Set its .Left and .Top properties to the passed values
>>>* Show it
>>>

Similarly, you could just pass in a reference to This.Parent, and let ShowCalendar() do all the arithmetic.

I looked in the debugger and these values (Parent.left and Parent.right) are what they would be if the entire form was opened in the upper left corner. But I am opening it Centered. This is what I asked the question (this thread) to see what I need to do after the form is centered.

Amazing that I have this calendar in my app since the late 90s and never had a problem. By some luck my forms were always positioned in the upper left corner so adding thisform.left and .top was not necessary. Only now when I created this form that has to be centered I realized - with your help - what I was missing.
I wanted to thank you again!
