c# - system.windows.forms.sendkeys.sendwait not working when window is maximize -

-

i sending keystrokes other running application using sendkeys.sendwait. not working if target application not minimize. wrong method? other methods send keystrokes running application.

code block using:

setforegroundwindow(handletoapplication);             system.windows.forms.sendkeys.sendwait(keystroke);

i suggest manipulating window prior sending keys it...

    private void setwindowstate(string windowtitle, int option)     {         /**         sw_hide             0         sw_shownormal       1         sw_normal           1         sw_showminimized    2         sw_showmaximized    3         sw_maximize         3         sw_shownoactivate   4         sw_show             5         sw_minimize         6         sw_showminnoactive  7         sw_showna           8         sw_restore          9         sw_showdefault      10         sw_forceminimize    11         sw_max              11         **/          process[] plist = process.getprocesses();         intptr handle = new intptr();          foreach (process x in plist)         {             if (x.mainwindowtitle == windowtitle)             {                 handle = x.mainwindowhandle;                 break;             }         }          showwindow(handle, option);     }
