_WinAPI_GetDlgCtrlID
Show description in
Returns the identifier of the specified control
#include <WinAPIDlg.au3>
_WinAPI_GetDlgCtrlID ( $hWnd )
Parameters
| $hWnd | Handle to the control |
Return Value
| Success: | Identifier of the control |
| Failure: | 0, call _WinAPI_GetLastError() to get extended error information |
Remarks
GetDlgCtrlID accepts child window handles as well as handles of controls in dialog boxes.
An application sets the identifier for a child window when it creates the window by assigning the identifier value to the hmenu parameter when calling the CreateWindow or CreateWindowEx function.
Although GetDlgCtrlID may return a value if $hWnd identifies a top-level window, top-level windows cannot have identifiers and such a return value is never valid.
