WPF: How do I position the mouse cursor in code?

Question

I am implementing the system menu (Restore, Move, Size...) on a borderless window and I want the mouse cursor to move to the center of the Window when size or move is selected. Ideally in VB but C# is fine as well.

Answer 1

You can use the SetCursorPos function, something like:

Declare Function SetCursorPos& Lib "user32" (ByVal p As Point)

'...

dim p as point
p.x = 100
p.y = 200
SetCursorPos p

Answer 2

A few tweaks and it seems to work:

Private Declare Function SetCursorPos Lib "user32" (ByVal x As Int32, ByVal Y As Int32) As Int32

...

With Win

  Dim left As Int32 = CInt(.Left + .Width - CURSOR_OFFSET_MEDIUM)
  Dim top As Int32 = CInt(.Top + .Height / 2)

  SetCursorPos(left, top)

End With
