[Resolved] GUICtrlCreateInput Limit Characters

[jfcby]

Hello,

I'm trying to limit the characters in a GUICtrlCreateInput control. When I use GUICtrlSetLimit it only works when the charactes or numbers are being typed in.

How can I set the character limit when I use GUICtrlSetData to change the input text?

#include <GUIConstantsEx.au3>

Example()

Func Example()
    Local $msg
    
    GUICreate("My GUI limit input 3 chars")  ; will create a dialog box that when displayed is centered

    GUICtrlCreateInput("", 10, 20)
    GUICtrlSetLimit(-1, 3)  ; to limit the entry to 3 chars
    
    GUISetState()

    ; Run the GUI until the dialog is closed
    While 1
        $msg = GUIGetMsg()
        
        If $msg = $GUI_EVENT_CLOSE Then ExitLoop
    WEnd
EndFunc   ;==>Example

Thank you for your help,

                If StringLen($NewText) > 3 Then
                    MsgBox(16, Default, "Text cannot be longer as 3 characters!")

                    GUICtrlSetData($Input, $NewText)

Check with an If statement?

If you're setting the data via the program, you have a couple of choices:

1) Use statements to validate the data being sent before sending (StringLen($string) will return the length)

2) Truncate the data sent (StringLeft($string, 3) will return the first 3 characters, StringRight() will do the right side)

jfcby,

Use GUICtrlSetData($hInput, StringLeft($sData, 3)).

Use GUICtrlSetData($hInput, StringLeft($sData, 3)).

Melba23 thank you for the code it works great.

I would like to thank each one for responding to my post. You were very helpful.

The answer now is so obvious but at the time I had no clue where to begin.

Thank you,
