Try this code. Points of interest: Checks if the window is (partially) visible on any screen’s working area. E.g. dragging it behind the task bar or moving it completely offscreen resets the position to windows default.

You can use EnumDisplayDevices to figure out what displays you have available and EnumDisplaySettings to get a list of available resolutions for your displays. Use ChangeDisplaySettings to set the resolution you need.

(and yes, it is the same name seen in resolution dialog) While I did add some personal touch to wrap this code I did not create the Hard-Core part of it, And so … Read more
Since the window is not yours, you can only move it by invoking the Windows API. You will have to do this: Launch the process. Use FindWindow to retrieve the handle to the window. If the window doesn’t exist yet, the process hasn’t created it yet; sleep for 500ms and then try again. (But don’t … Read more
You need to use the Screen class to find a screen that the original form is not on, then set the second form’s Location property based on that screen’s Bounds. For example: var myScreen = Screen.FromControl(originalForm); var otherScreen = Screen.AllScreens.FirstOrDefault(s => !s.Equals(myScreen)) ?? myScreen; otherForm.Left = otherScreen.WorkingArea.Left + 120; otherForm.Top = otherScreen.WorkingArea.Top + 120; This … Read more
this.Location = Screen.AllScreens[1].WorkingArea.Location; this is the Form reference.
public static void showOnScreen( int screen, JFrame frame ) { GraphicsEnvironment ge = GraphicsEnvironment .getLocalGraphicsEnvironment(); GraphicsDevice[] gs = ge.getScreenDevices(); if( screen > -1 && screen < gs.length ) { gs[screen].setFullScreenWindow( frame ); } else if( gs.length > 0 ) { gs[0].setFullScreenWindow( frame ); } else { throw new RuntimeException( “No Screens Found” ); } }
