InstallPopup overwrite window topmost status

[zou]

My CVI dll popup a main panel as topmost window.  That works fine.  Problem start when I need popup another dialog window on top of the main CVI window.  I used InstallPopup.  The popup window got a correct relation with the main window, but both CVI windows lost topmost status.  So they can be covered by the dll caller (LabVIEW).  When I close the popup window, the main panel get its topmost status back mysteriously.

When I call Set attributes for setting topmost programmatically, I got an runtime error, saying that I can't do that while the popup is running.

I did manage to get topmost back by Window API calls.  Don't know if this the right way. 

Anyone run into this before ?

How are you removing the popup?

Thanks for reply ngay528.

My main panel is NOT a modal (popup).  I don't know how to make it a modal.  InstallPopup doesn't work in this case.  The caller is LabVIEW.

So I don't use RemovePopup.
