Count char and reset GUI

[moczymorda]

This is sample of my script:

expandcollapse popup

#include <GUIConstants.au3>
#include <array.au3>

#Region ### START Koda GUI section ### Form=
$Form1 = GUICreate("Char count", 703, 500, 193, 115)

GUICtrlCreateGroup("", -99, -99, 1, 1)
$Group2 = GUICtrlCreateGroup("Load file", 8, 15, 250, 81)
$Path = GUICtrlCreateInput("", 16, 47, 145, 21)
$Browse = GUICtrlCreateButton("Browse", 168, 47, 81, 22, 0)

GUISetState(@SW_SHOW)
#EndRegion ### END Koda GUI section ###

While 1
    $msg = GUIGetMsg()

        Switch $msg
        Case $GUI_EVENT_CLOSE
        Exit
    EndSwitch
    
    If $msg = $Browse Then

        $file = FileOpenDialog("open","C:\","(*.txt)",3,"",$Form1)
        If @error Then ContinueLoop
        GUICtrlSetData($Path, $file)
        
        $PathSv = GUICtrlRead($Path)
        
    Local $aAlph = StringSplit('abcdefghijklmnopqrstuvwxyz', '')
    Local $aArray[UBound($aAlph)], $sString = FileRead($PathSv)
    For $iCC = 1 To UBound($aAlph) - 1
        StringReplace($sString, $aAlph[$iCC], '')
        $aArray[$iCC] = @extended
        
GUICtrlCreateGraphic(23, 91+$iCC*15, $aArray[$iCC], 10)
GUICtrlSetBkColor(-1, 0xffffff)
GUICtrlSetColor(-1, 0)
GUICtrlCreateLabel($aAlph[$iCC], 10, 89+$iCC*15, 10, 11)
GUICtrlCreateLabel($aArray[$iCC], 23+$aArray[$iCC]+5, 89+$iCC*15, 36, 11)           
            
            
    Next

    EndIf   
    
WEnd

Using WM_PAINT and GDI drawing:

expandcollapse popup

#include <GUIConstants.au3>#include <array.au3>


#include <WinAPI.au3>

Global Const $TRANSPARENT = 1

Global $aAlph = StringSplit(&apos;abcdefghijklmnopqrstuvwxyz&apos;, &apos;&apos;)
Global $aArray[UBound($aAlph)]
$gdi_dll = DllOpen("gdi32.dll")

#Region ### START Koda GUI section ### Form=
$Form1 = GUICreate("Char count", 703, 500, 193, 115)
$pic = GUICtrlCreatePic("",53,91,700,500)
;~ GuiCtrlSetState($pic,$GUI_DISABLE)
$pic_hWnd = ControlGetHandle($Form1,"",$pic)
$hdc = _WinAPI_GetDC($pic_hWnd)

GUICtrlCreateGroup("", -99, -99, 1, 1)
$Group2 = GUICtrlCreateGroup("Load file", 8, 15, 250, 81)
$Path = GUICtrlCreateInput("", 16, 47, 145, 21)
