Tip 118: Converting a Word for Windows Document to RTF Format
July 1, 1995
In a Microsoft® Visual Basic® application, you may need to convert a Microsoft
Word for Windows® version 6.0 document to rich-text format (RTF). This article
explains how this can be accomplished in Visual Basic.
Using OLE Automation in Visual Basic
You can use OLE Automation in a Microsoft® Visual Basic® application to perform
specific tasks in another Microsoft Windows®-based application. For example, you
may need to convert a Microsoft Word for Windows version 6.0 document to rich-text
The example program below shows how to run Word for Windows, load an existing
document into Word, and then save that document to disk in RTF format. The OLE
commands sent to Microsoft Word enable you to have total control over Word; that
is, from within Visual Basic you can tell Word exactly what to do and when to do
In this example program, you need some way to communicate with Microsoft Word. You
do this by creating an object variable for Word. In this case, you use WordBasic.
Next, you tell Microsoft Word that you want to load a specific document.
Therefore, you tell Word to carry out a FileOpen command to load the document into
In the same manner, you use the object variable to tell Word to save the document
(using the WordBasic FileSaveAs command) in RTF format. You must specify both a
file name for the document and the file format in which you want to save the
document. Because you want to save the file as an RTF document, specify the value
6 for RTF.
After Word has saved the document in RTF format, you want to exit Word and return
to your Visual Basic application. This is done by setting the object variable to
Nothing, which closes the server application.
This program shows how to use OLE Automation to convert a Microsoft Word for
Windows 6.0 document to RTF format from within a Visual Basic application.
1. Create a new project in Visual Basic. Form1 is created by default.
2. Add a Command Button control to Form1. Command1 is created by default. Set
its Caption property to "Convert to RTF".
3. Add the following code to the Click event for Command1:
Private Sub Command1_Click()
Dim Obj As Object
Set Obj = CreateObject("Word.basic")
Obj.FileSaveAs "c:\demo.rtf", 6
Set Obj = Nothing
MsgBox "Document converted to RTF format"
Note This program assumes that you have a Word for Windows 6.0 document named
DEMO.DOC stored in the root directory of drive C. This document will be
converted to RTF format and stored on drive C as DEMO.RTF.
Run the example program by pressing F5. Click the "Convert to RTF" command
button. Visual Basic runs Microsoft Word, loads DEMO.DOC into memory, and saves
a new copy of the document to disk in RTF format. A message box is displayed when
the whole process has been completed.
