HEEELP :( GET the maximum number OF STRING supported IN A LABEL

[Celtic88 18]

halllo  I'm looking for another solution for detect the maximum number OF STRING supported IN A LABEL 

exempl :

expandcollapse popup

#include <StaticConstants.au3>
$stringsiz = 30
Global $txt
$ol = GUICreate("My GUI", 560, 540)
$iLabel = GUICtrlCreateLabel("Initial text...", 0, 0, 300, 40, $SS_CENTER)
GUICtrlSetBkColor(-1, 0xffffff)
GUICtrlSetFont(-1, $stringsiz)
$cbou = GUICtrlCreateButton("NEXT", 2, 80, 50, 50)
GUISetState()

$txt = "abcdefghijklmnopqrstuvwxyzbcdefghijklmnopqrstuvwxyzbcdefghijklmnopqrstuvwxyz"
$n = getsiz($ol, $iLabel, $txt)
GUICtrlSetData($iLabel, StringLeft($txt, $n))
$txt = StringTrimLeft($txt, $n)

Do
    $msg = GUIGetMsg()
    If $msg = $cbou Then
        $n = getsiz($ol, $iLabel, $txt)
        GUICtrlSetData($iLabel, StringLeft($txt, $n))
        $txt = StringTrimLeft($txt, $n)
    EndIf
Until $msg = -3

Func getsiz($zgui, $labctrl, $txtt)
    Local $a, $oo, $Zz, $iiz = 1, $n, $ppoo
    $a = ControlGetPos($zgui, "", $labctrl)
    While 1
        For $iiz = $iiz To StringLen($txtt) step 3
            $Zz &= StringMid($txtt, $iiz, 3)
            $oo = _StringSize($Zz, $stringsiz)
            If $oo[0] >= $a[3] Then ExitLoop
        Next
        $ppoo += $oo[1]
        If $ppoo >= $a[2] Then ExitLoop
        $n += StringLen($Zz)
        $Zz = ""
    WEnd
    Return $n
EndFunc   ;==>getsiz
Func _StringSize($sString, $iSize = 9, $iWeight = 400, $sFontName = "")
    Local $hWnd, $hGuiSwitch, $iCtrlID, $aCtrlSize, $aRetSize[2] = [0, 0]
    $hWnd = GUICreate("StringExInternalWin", 0, 0, 0, 0, BitOR(0x80000000, 0x20000000), BitOR(0x00000080, 0x00000020))
    $hGuiSwitch = GUISwitch($hWnd)
    If $iSize = 65535 Then ; Used by _ImageSize
        $iCtrlID = GUICtrlCreatePic($sString, 0, 0, 0, 0)
    Else
        GUISetFont($iSize, $iWeight, -1, $sFontName, $hWnd)
        $iCtrlID = GUICtrlCreateLabel($sString, 0, 0)
    EndIf
    $aCtrlSize = ControlGetPos($hWnd, "", $iCtrlID)
    GUIDelete($hWnd)
    GUISwitch($hGuiSwitch)
    If IsArray($aCtrlSize) Then
        $aRetSize[0] = $aCtrlSize[2]; Width
        $aRetSize[1] = $aCtrlSize[3]; Height
        Return SetError(0, 0, $aRetSize)
    EndIf
    Return SetError(1, 0, $aRetSize)
EndFunc   ;==>_StringSize

thank you

Mrbenkali,

My StringSize UDF (look in my sig for the link) tells you the dimensions of any string in any font at any size - is that what you want?

I do not want to change the size of LABEL , but I want to change the number of characters

Mrbenkali,

One of the examples with the UDF determines the largest font size to fit a certain message into a given label size - is that what you are trying to do?

Edit: Just checked - Example 4 is the one you want.
