ControlGetHwnd

Returns the unique ID number of the specified control.

Hwnd := ControlGetHwnd(Control , WinTitle, WinText, ExcludeTitle, ExcludeText)

Parameters

Control

Type: String, Integer or Object

The control's ClassNN, text or HWND, or an object with a Hwnd property. For details, see The Control Parameter.

WinTitle

Type: String, Integer or Object

A window title or other criteria identifying the target window. See WinTitle.

WinText

Type: String

If present, this parameter must be a substring from a single text element of the target window (as revealed by the included Window Spy utility). Hidden text elements are detected if DetectHiddenText is ON.

ExcludeTitle

Type: String

Windows whose titles include this value will not be considered.

ExcludeText

Type: String

Windows whose text include this value will not be considered.

Return Value

Type: Integer

This function returns the window handle (HWND) of the specified control.

Error Handling

An exception is thrown if the window or control could not be found.

Remarks

A control's HWND is often used with PostMessage, SendMessage, and DllCall. On a related note, a control's HWND can also be retrieved via MouseGetPos. Finally, a control's HWND can be used directly in a WinTitle parameter. This also works on hidden controls even when DetectHiddenWindows is Off.

Window titles and text are case sensitive. Hidden windows are not detected unless DetectHiddenWindows has been turned on.
