I will start from beginning, I aw working on an application which will span over multiple monitors, each monitor will contain a single WPF window and these windows are controled using a single viewmodel class. now lets say i have a button on all the windows at 200,300 (x,y) and i want that this button should be responsible for a tool on same window, while all rest are responsible for the application.
When i try to get current mouse position or last click position i get position relative to the current monitor , i.e. in this case 200,300, irrespective of in what screen i am on.
following sre the code i tried for getting mouse position
[DllImport("user32.dll")]
[return: MarshalAs(UnmanagedType.Bool)]
internal static extern bool GetCursorPos(ref Win32Point pt);
[StructLayout(LayoutKind.Sequential)]
internal struct Win32Point
{
public Int32 X;
public Int32 Y;
};
public static Point GetMousePosition()
{
Win32Point w32Mouse = new Win32Point();
GetCursorPos(ref w32Mouse);
return new Point(w32Mouse.X, w32Mouse.Y);
}
Point point = Control.MousePosition;
Mouse.GetPosition(null);
following is the code which should return me the screen no.
private int ConvertMousePointToScreenIndex(System.Windows.Point mousePoint)
{
//first get all the screens
System.Drawing.Rectangle ret;
for (int i = 1; i <= System.Windows.Forms.Screen.AllScreens.Count(); i++)
{
ret = System.Windows.Forms.Screen.AllScreens[i - 1].Bounds;
if (ret.Contains(new System.Drawing.Point((int)mousePoint.X, (int)mousePoint.Y)))
return i - 1;
}
return 0;
}
I always get screen as 0 :(
Please help me in getting appropriate value
