[RESOLVED] getting the handles ?

how can i get the handles of

1) the start button on the task bar

and

2)the systemtray on the task bar

You can use the Spy++ tool ( VisualCInstallFolder\Common7\Tools) to grab the window hierarchy from the desktop and then use FindWindowEx to navigate to the desired button/window.

On my machine running XP, from the destop the hierarchy is as follows

Code:

---


        Title      Class
Root  NULL          #32769 (Desktop)
 L      NULL          Shell_Tray
  L    "start"        Button
 L      NULL          TrayNotifyWnd
  L    "11:02 AM"  TrayClockWClass
  L    NULL          SysPager
  L    NULL          Button

---

Another way to approach this (and a more reliable way, imo) is to use Active Accessibility. AA gives you more control over accessing UI entities that may not be available using other windowing techniques (like FindWindow, EnumWindows, etc.)

1)HWND hShellTrayWnd = ::FindWindow(_T("Shell_TrayWnd"), NULL);

2) HWND hStartButton = ::FindWindowEx(hShellTrayWnd,0,"Button","start");

i got system traywindow handle .
but start buttons handle.what wrong with 2 plz correct

Code:

HWND hShellTrayWnd = NULL, hStartBtn = NULL;


if( NULL != ( hShellTrayWnd = ::FindWindowEx( NULL, NULL, _T("Shell_TrayWnd"), NULL ) ) )
{
  hStartBtn = ::FindWindowEx( hShellTrayWnd, NULL, _T("Button"), _T("start") );
}

Again, this works on XP. For other operation systems like Vista and Win7, the hierarchy, class names and/or title names may change.
