How to get the (0, 0)th location

Hi,

I am using menubar and toolbar, statusbar in my dialog, Now, I want to put an activeX control which should have its window from (0, 0)th location of the dialog till the (maxX, maxY) position in the dialog.

Now, If I simply use this code,

pMyCustomCtl->SetWindowPos(NULL, xLeftTop, yLeftTop, 250, 250, SWP_NOSIZE);

Now, what this line does is put my control on the first pixel of my dialog.. which overrides my menu and toolbar control.. And if going till the end of hte dialog, it goes above the status bar too.. So, how can I get the co-ordinate (0, 0) after menubar and toolbar gets completed.. ?? I may have more than one row for toolbar.. so, i can not add constant to get hte location.. I hope you understand my question..
