    I made this code to save text file. But now I am wondering how to save a file if there is an existing file name. I would like to add a mnuItemSave for that. Is it work? How to code that?

    Private Sub mnuItemsave_Click()
    CommonDialog1.Filter = "Text files (*.TXT)|*.TXT"
    CommonDialog1.ShowSave 'display Save dialog
    If CommonDialog1.FileName <> "" Then
    Open CommonDialog1.FileName For Append As #1
    Print #1, txtFile.Text 'save string to file
    Close #1 'close file
    End If
    End Sub

    Private Sub mnuItemOpen_Click()
    Wrap$ = Chr$(13) + Chr$(10) 'create wrap character
    CommonDialog1.Filter = "Text files (*.TXT)|*.TXT|EXCEL files (*.xls)|*.xls|All Files (*.*)|*.*"
    CommonDialog1.ShowOpen 'display Open dialog box
    If CommonDialog1.FileName <> "" Then
    ' Form1.MousePointer = 11 'display hourglass
    Open CommonDialog1.FileName For Input As #1

    ' On Error GoTo TooBig: 'set error handler

    Do Until EOF(1) 'then read lines from file
    Line Input #1, LineOfText$
    AllText$ = AllText$ & LineOfText$ & Wrap$
    Loop
    lblFile.Caption = CommonDialog1.FileName
    txtFile.Text = AllText$ 'display file
    txtFile.Enabled = True
    mnuItemClose.Enabled = True
    mnuItemOpen.Enabled = False
    End If
    Close #1
    'CleanUp:
    ' Form1.MousePointer = 0 'reset mouse
    ' Close #1 'close file
    ' End If
    'Exit Sub
    'TooBig: 'error handler displays message
    ' MsgBox ("The specified file is too large.")
    ' Resume CleanUp: 'then jumps to CleanUp routine
    End Sub


    Private Sub mnuItemClose_Click()
    txtFile.Text = "" 'clear text box
    lblFile.Caption = "Load a text file with the Open command."
    mnuItemClose.Enabled = False 'dim Close command
    mnuItemOpen.Enabled = True 'enable Open command
    txtFile.Enabled = False 'disable text box
    End Sub

    Private Sub mnuItemExit_Click()
    End 'quit program
    End Sub

    thanks

    Let's see if I understand this. You want to save a file if the user has already specified a file name. Is this what you mean? In the following, when the user specifies a file name, it's saved as a module-level variable (not inside a subroutine), LastFileName. If the user clicks a menu item labeled "Save Existing" (mnuSaveExisting), it calls the second subroutine, below. That subroutine checks the LastFileName variable to make sure that it's not empty and then does the same thing that the mnuItemsave_click subroutine does -- except it doesn't call the CommonDialog1 object.

    Private LastFileName As String

    Private Sub mnuItemsave_Click()
    CommonDialog1.Filter = "Text files (*.TXT)|*.TXT"
    CommonDialog1.ShowSave 'display Save dialog
    If CommonDialog1.FileName <> "" Then
    LastFileName = CommonDialog1.FileName
    Open CommonDialog1.FileName For Append As #1
    Print #1, txtfile.Text 'save string to file
    Close #1 'close file
    End If
    End Sub

    Private Sub mnuExisting_Click()
    If LastFileName <> "" Then
    Open LastFileName For Append As #1
    Print #1, txtfile.Text 'save string to file
    Close #1 'close file
    End If
    End Sub
