Changes the text of a control.

ControlSetText NewText , Control, WinTitle, WinText, ExcludeTitle, ExcludeText



The new text to set into the control. If blank or omitted, the control is made blank.


Can be either ClassNN (the classname and instance number of the control) or the control's text, both of which can be determined via Window Spy. When using text, the matching behavior is determined by SetTitleMatchMode. If this parameter is blank, the target window's topmost control will be used.

To operate upon a control's HWND (window handle), leave the Control parameter blank and specify "ahk_id " ControlHwnd for the WinTitle parameter (this also works on hidden controls even when DetectHiddenWindows is Off). The HWND of a control is typically retrieved via ControlGetHwnd, MouseGetPos, or DllCall.


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


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.


Windows whose titles include this value will not be considered.


Windows whose text include this value will not be considered.


ErrorLevel is set to 1 if there was a problem or 0 otherwise.


Most control types use carriage return and linefeed (`r`n) rather than a solitary linefeed (`n) to mark the end of each line. To translate a block of text containing `n characters, follow this example:

MyVar := StrReplace(MyVar, "`n", "`r`n")

To improve reliability, a delay is done automatically after every use of this function. That delay can be changed via SetControlDelay.

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