I am confused about the Windows calculator. I would like to employ it to return a result back to a text box that had focus before the calculator was invoked. I believe I want to use the dblclick method to invoke the calculator. Where I am confused is that the window that pops up is not modal. I want the window to close and be able to populate the value property of the text box that had focus. So what event takes place when I close the window?

To me, the VFP explanation was too vague for _calvalue and _calcmem.

Thank you in advance.
