Hi,
U cannot Control the position of CommonDialog control. But there is an alternative, Place the common Dialog on a New Form, and Move the Form to Desired position on Screen and Show the Form.
Some thing like this : Add a Form And Rename it as frmColor:
Dim frmColor As New frmColor
frmColor.Move 200,500
frmColor.cdlg.ShowColor
Not very sure abt system colors...
Regards
Veena
