my wpf application has button when pressed, opens notepad. need open notepad in x, y coordinates, how do that? want open program, open notepad , place in (500,1000) (x, y).
<window x:class="movewindow.mainwindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:local="clr-namespace:movewindow" mc:ignorable="d" title="mainwindow" windowstartuplocation="manual" height="350" width="500"> <frameworkelement width="110" /> </window> this xaml.cs part:
using system; using system.collections.generic; using system.diagnostics; using system.linq; using system.text; using system.threading.tasks; using system.windows; using system.windows.controls; using system.windows.data; using system.windows.documents; using system.windows.input; using system.windows.media; using system.windows.media.imaging; using system.windows.navigation; using system.windows.shapes; namespace movewindow { /// <summary> /// interaction logic mainwindow.xaml /// </summary> public partial class mainwindow : window { public mainwindow() { initializecomponent(); left = 0; top = 0; // process.start("notepad.exe"); } } }
you can use (@as rehan said), movewindow.
check solution (in case be):
public mainwindow() { initializecomponent(); var notepadprocess = process.start("notepad.exe"); if (notepadprocess != null) { notepadprocess.waitforinputidle(); // positioning @ x=100, y=100 width of: 500 , height of: 200 custommove(notepadprocess, 100, 100, 500, 200); } } public void custommove(process process, int x, int y, int width, int height) { var ok = movewindow(process.mainwindowhandle, x, y, width, height, true); if (ok == false) messagebox.show("couldn't move window!"); } [dllimport("user32.dll", setlasterror = true)] private static extern bool movewindow(intptr hwnd, int x, int y, int width, int height, bool repaint); the first parameter of movewindow window handler pointer (which process's handle).
the second & third x , y position on screen
the fourth & fifth width , height of window
the sixth parameter :
indicates whether window repainted. if parameter true, window receives message. if parameter false, no repainting of kind occurs. applies client area, nonclient area (including title bar , scroll bars), , part of parent window uncovered result of moving child window.
however if need more details method, checkout link: https://msdn.microsoft.com/en-us/library/windows/desktop/ms633534(v=vs.85).aspx
