New Line on GUICtrlSetData

Recommended Posts

jessem

I'm trying to read from a file and display all of the single lines into a GUICtrlCreateLabel using GUICtrlSetData. I'm certain it can be done, and I'm almost more certain I'm not doing it correctly!

As an excersise for myself, I'm trying to write to a chat.txt file and that when pushing the button Update will add updated test to that file and then print it out for me up top. Here is the script.

#include <guiconstants.au3>
#include <string.au3>


$WinMain = GuiCreate('Clever Chat', 400, 400);Main Window
$DisplayText = GUICtrlCreateLabel('',5,5,380,150,$SS_SUNKEN)
$AddToText = GUICtrlCreateEdit('',5,180,380,150, $WS_EX_TRANSPARENT)
$UpdateButton = GuiCtrlCreateButton('Update', 170, 340, 80, 35)

GuiSetState()


Do
   $Msg = GuiGetMsg()
   
   If $msg = $UpdateButton Then
    
    $ChatFile = FileOpen("C:\chat.txt", 1)
        If $ChatFile = -1 Then
        MsgBox(0, "Error", "Unable to open file.")
        Exit
        EndIf
    
    $NewText = FileWriteLine($ChatFile, GUICtrlRead ($AddToText));Updates the chat.txt from lower inputline.
    FileClose($ChatFile)
    GUICtrlSetData($AddToText,'')
FileClose($ChatFile)


;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
;UPDATE THE TOP WINDOW
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
$OpenFileToRead = FileOpen("C:\chat.txt", 0)

; Check if file opened for reading OK
If $OpenFileToRead = -1 Then
    MsgBox(0, "Error", "Unable to open file.")
    Exit
EndIf

; Read in lines of text until the EOF is reached
While 1
    $line = FileReadLine($OpenFileToRead)
    If @error = -1 Then ExitLoop
       GUICtrlSetData($DisplayText,$line);Updating message
Wend

FileClose($OpenFileToRead)

     EndIf
Until $msg = $GUI_EVENT_CLOSE; Continue loop untill window is closed

Oh i see now, well, you need to update not one line at the time, you can read the whole file and update with the content:

#include <guiconstants.au3>
#include <string.au3>


$WinMain = GuiCreate('Clever Chat', 400, 400);Main Window
$DisplayText = GUICtrlCreateLabel('',5,5,380,150,$SS_SUNKEN)
$AddToText = GUICtrlCreateEdit('',5,180,380,150, $WS_EX_TRANSPARENT)
$UpdateButton = GuiCtrlCreateButton('Update', 170, 340, 80, 35)

GuiSetState()


Do
   $Msg = GuiGetMsg()
   
    If $msg = $UpdateButton Then
        $ChatFile = FileOpen("c:\chat.txt", 1)
        If $ChatFile = -1 Then
            MsgBox(0, "Error", "Unable to open file.")
            Exit
        EndIf
        
        $NewText = FileWriteLine($ChatFile, GUICtrlRead($AddToText));Updates the chat.txt from lower inputline.
        FileClose($ChatFile)
        GUICtrlSetData($AddToText, '')
        FileClose($ChatFile)
        
        ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
        ;UPDATE THE TOP WINDOW
        ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
        GUICtrlSetData($DisplayText, FileRead("c:\chat.txt"));Updating message
    EndIf
Until $msg = $GUI_EVENT_CLOSE; Continue loop untill window is closed

Or if you want to do this in your way (with the loop), you will have to read the current data of the label every time you want to add new line (e.g: GUICtrlSetData($DisplayText, GuiCtrlRead($DisplayText) & @CRLF & $line)).
