#include <GUIConstants.au3>
#include <File.au3>
#include <String.au3>

Local $Form1 = GUICreate("AForm1", 625, 443, 193, 115)
Local $Label1 = GUICtrlCreateLabel("dsasd", 32, 16, 577, 412)
GUICtrlSetFont(-1, 14, 400, 0, "MS Sans Serif")
GUICtrlSetColor(-1, 0xFF0000)
GUISetState(@SW_SHOW)

Local $readtext = _FileCountLines(@ScriptDir & "\a.txt")
For $i = 1 To $readtext
    $linetext = FileReadLine(@ScriptDir & "\a.txt", $i)
    $Str = StringSplit($linetext, "")
    For $o = 1 To $Str[0]
        GUICtrlSetData($Label1, GUICtrlRead($Label1) & StringMid($linetext, $o, 1))
        If ($o == $Str[0]) Then GUICtrlSetData($Label1, GUICtrlRead($Label1) & @CRLF)
        Sleep(20)
    Next
Next

While 1
    $nMsg = GUIGetMsg()
    Switch $nMsg
        Case $GUI_EVENT_CLOSE
            Exit
    EndSwitch
WEnd
 

---> Works Well

but there is a problem 

 

it continuously blinks and looks so bad how all the characters on screen are standing still and not blink

Translates to:

"I wrote a program that reads a text file and then print it out slowly"

Adjust the Sleep(20) and see what happens. Try Sleep(100)

[UEZ]

Try:

 

include <GUIConstants.au3>
#include <File.au3>
#include <String.au3>
#include <WindowsConstants.au3>


Local $Form1 = GUICreate("AForm1", 625, 443, 193, 115, Default,BitOR($WS_EX_COMPOSITED, $WS_EX_LAYERED))
...

I have a problem anymore 

 

if I put 

 

sleep (10) or sleep (50) 

 

still blinks

[UEZ]

I cannot see any blinking when changing the sleep value.

What you can try is to use GDI+ to have flicker free text printing. There are several examples how to use GDI+ for such tasks.
