Function Reference


_WinAPI_GetDlgCtrlID

Returns the identifier of the specified control

#include <WinAPI.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.
