Richard,
To get the hwnd for MI Dialog you have to loop through all child windows of MI window
and find the the MDIClient window (for example by using GetClassName API). Then loop
again through child windows of MDIClient and one of those is your Dialog window.
(By the way by looping through child windows of this Dialogbox you are able to access
all dialog controls which can be modified with SendMessage function.)
Let me know if you have problems with my explaination. Have fun.
Regards,
Anssi

Subject: MI MB: How do I query dialog position (Win API?)
