CFileDialog code generator

To often I have found my self in a situation where i needed to save or open a file through the standard common dialogs. The MFC implementation of the common dialog is quite elegant, but it involves alot of parameters, which are often hard to remember.

This macro will take you through a few steps, in a wizard like mode, and create the right code for you.

FileDialogHandler


Sub FileDialogHandler()
'DESCRIPTION: Automatically inserts the statements needed for a file-open/file-save dialog

    dim strExt

    ActiveDocument.Selection.StartOfLine dsFirstText
    ActiveDocument.Selection = " CFileDialog dlg("
    if bAnswer = vbYes then
    ActiveDocument.Selection = "FALSE"
    else
    ActiveDocument.Selection = "TRUE"
    bSaveDialog = 0
    end if

    ' The extension of the file
    strExt = InputBox("What is the extension of the filetype?", "Extension", "txt")
    ' The name of the file
    strName = InputBox("What is the name of the filetype?", "Name", "Text File")

    ' Only apply a default extension if it is a save-as dialog
    if bAnswer = vbYes then
        ActiveDocument.Selection = ",""*." & strExt & """"
    else
        ActiveDocument.Selection = ", """""
    end if

A note about WriteLn

Because of compatibility reasons (I dont want people to have to copy one macro to use another), I have not used the function below to write text. However it is pretty handy, and will make your code look alot better. It does the same as WriteLn from pascal.
This function is not meant to be called by the user, but only from other scripts.


sub writeln(line)
    ActiveDocument.Selection.StartOfLine dsFirstText
    ActiveDocument.Selection = line
    ActiveDocument.Selection.NewLine
end sub

    The code as published puts the dialog title without surrounding quotes. To change this behavior, change the line that reads:

    ActiveDocument.Selection = " dlg.m_ofn.lpstrTitle = " & caption & ";"

    to
    ActiveDocument.Selection = " dlg.m_ofn.lpstrTitle = """ & caption & """;"
