Use dachart.screenx, dachart.screeny. and you will have what you want. It's the position of the control on the entire screen. Le 5 févr. 2014 16:42, "Louis W. Adams, Jr." <louiswadam...@charter.net> a écrit : I have a drawing area control daChart on a form. To extract an image of that control area using screenshot, I expected that the following would work, where picSave is a Picture object. The number 28 accounts for the window control frame at the top for my screen resolution in Ubuntu (1920x1080). picSave = Desktop.Screenshot() With daChart picSave = picSave.Copy(Me.Left + .X, Me.Top + .Y + 28, .Width, .Height) End With Instead I must do what follows. picSave = Desktop.Screenshot() With daChart If (Me.Left > 0) Then picSave = picSave.Copy(Me.Left + 2 * .X, Me.Top + 2 * .Y + 28, .Width, .Height) Else picSave = picSave.Copy(Me.Left + .X + 1, Me.Top + .Y + 28, .Width, .Height) Endif End With In other words, if the form is not at the left edge of the desktop then I must double the drawing area control coordinates. I see nothing wrong with coordinate values of the form or the control as reported by the debugger, and Screenshot() is unaffected by form location on the desktop, so the problem might be in the Copy method.
