c# - Finding multiple windows with the same title -

i starting executable several times this

process proc = new process(); proc.startinfo.filename = path + "/builtgame.exe"; proc.start();  process proc1 = new process(); proc1.startinfo.filename = path + "/builtgame.exe"; proc1.start(); 

now want resize , move spawned windows.

i using movewindow , findwindow

[dllimport("user32.dll", setlasterror = true)] internal static extern bool movewindow(intptr hwnd, int x, int y, int nwidth, int nheight, bool brepaint); [dllimport("user32.dll", setlasterror = true)] internal static extern intptr findwindow(string windowclass, string title); 

initially thought use handle spawned process

 movewindow(proc.handle, 0, 0, 100, 100, true); 

but didn't work , tried use findwindow

intptr handle = findwindow(null,"mywindowtitle") 

which indeed worked , returned handle findwindow different 1 process.handle

after tried use

 movewindow(proc.mainwindowhandle, 0, 0, 100, 100, true); 

but mainwindowhandle 0.

the problem have want start multiple processes , correct window handle each window findwindow returns first one.

how this?

call enumwindows enumerate top-level windows. each such window, call getwindowtext find out text can compare against target value.

if looking windows in specific process, use getwindowthreadprocessid.
