GUI - *.txt file Communication?

[locoforcoco9]

Is there any way I can make a GUI append text to a named file, and then later on retrieve that text?

Like, if the user types in a word, let's say "Geass", and presses a button, then the GUI will edit USERTEXT.txt to have "Geass" instead of whatever was in it, or append it to whatever was in it.

THEN, for a GUI (same, different, does it matter?) to retrieve that text later on.

Phew, any ideas?

Thanks,

EDIT:

Side-question:

Can I disable a GUImenuItem? Like, have it still there, but just non-clickable?

locoforcoco9,

Here is one very simplistic way you could do it:

expandcollapse popup

#include <GUIConstantsEx.au3>

$sFile = "UserTxt.txt"

$hGUI_1 = GUICreate("Input", 200, 200, 100, 100)

GUICtrlCreateLabel("Enter the text here:", 10, 10, 180, 20)
$hInput = GUICtrlCreateInput("", 10, 50, 180, 20)
$hButton_1 = GUICtrlCreateButton("Save", 10, 100, 80, 30)

GUISetState()

$hGUI_2 = GUICreate("Retrieval", 200, 200, 400, 100)

GUICtrlCreateLabel("The last text saved was:", 10, 10, 180, 20)
$hLabel = GUICtrlCreateLabel("", 10, 50, 180, 20)
$hButton_2 = GUICtrlCreateButton("Retrieve", 10, 100, 80, 30)

GUISetState()

GUISwitch($hGUI_1)

While 1

    $aMsg = GUIGetMsg(1)
    Switch $aMsg[1]
        Case $hGUI_1
            Switch $aMsg[0]
                Case $GUI_EVENT_CLOSE
                    Exit
                Case $hButton_1
                    $hFile = FileOpen($sFile, 2)
                    FileWrite($hFile, GUICtrlRead($hInput))
                    FileClose($hFile)
                    GUICtrlSetData($hLabel, "")
            EndSwitch
        Case $hGUI_2
            Switch $aMsg[0]
                Case $GUI_EVENT_CLOSE
                    Exit
                Case $hButton_2
                    If FileExists($sFile) Then
                        GUICtrlSetData($hLabel, FileRead($sFile))
                    Else
                        GUICtrlSetData($hLabel, "Nothing saved")
                    EndIf
            EndSwitch
    EndSwitch

WEnd

You might want to read the Managing Multiple GUIs tutorial in the Wiki if you find the While...WEnd loop a bit complex.

Please ask if you have any questions.

P.S. As to disabling a menuitem, look at GUICtrlSetState in the Help file.
