Changes the text of a control.
ControlSetText NewText, Control , WinTitle, WinText, ExcludeTitle, ExcludeText
Type: String
The new text to set into the 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.
Type: String, Integer or Object
If each of these is blank or omitted, the Last Found Window will be used. Otherwise, specify for WinTitle a window title or other criteria to identify the target window and/or for WinText a substring from a single text element of the target window (as revealed by the included Window Spy utility).
ExcludeTitle and ExcludeText can be used to exclude one or more windows by their title or text. Their specification is similar to WinTitle and WinText, except that ExcludeTitle does not recognize any criteria other than the window title.
Window titles and text are case-sensitive. By default, hidden windows are not detected and hidden text elements are detected, unless changed with DetectHiddenWindows and DetectHiddenText; however, when using pure HWNDs, hidden windows are always detected regardless of DetectHiddenWindows. By default, a window title can contain WinTitle or ExcludeTitle anywhere inside it to be a match, unless changed with SetTitleMatchMode.
A TargetError is thrown if the window or control could not be found.
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 each use of this function. That delay can be changed via SetControlDelay or by assigning a value to A_ControlDelay. For details, see SetControlDelay remarks.
