Get Handle to WIL Dialog Control

 Keywords: obtain get handle WIL dialog control id number name GetDlgItem DllCall DialogProcOptions

Update:

WinBatch 2010A January 27, 2010
   Added DialogControlGet request-code 19 which accepts the name of a regular control
   and returns a window handle. The request cannot be used on MENUITEM and MENUBAR 
   controls because these controls are not windows.


A User Defined Function that obtains a handle to a dialog control, when passed the name of the control.

IMPORTANT: the control id is set by the tab order of the controls in the dialog. But it is a little more complicated than that because of group boxes. So in order for DlgGetItem to work by adding 99, the control number and the tab order must follow the same sequence!
