Leverage Office to Spellcheck RichText

Integrate Microsoft Word 97's spellchecking capability into VB apps while maintaining formatting within a rich textbox. To test this code:
1. Create a standard EXE project in VB.
2. Add the RichTextBox control from the Components menu.
3. Add a reference to the Microsoft Word 8.0 Object Library.
4. Drop a RichTextBox and a CommandButton onto the form.
5. Rename the RichTextBox to rtfText.
6. Change the caption of the CommandButton to Spell Check.
7. In the Click event of the CommandButton, add the next code listing.
8. Save and run the project.
9. Type some text in the RTF box and click on the CommandButton to check the spelling.
 
On Error GoTo SpellCheckErr
	Dim oWord As Object

	Set oWord = CreateObject("Word.Application")

	'Save the RTF Box contents to a temporary file
	rtfText.SaveFile "C:\TEST.RTF", rtfRTF

	'Open the saved document and spellcheck it
	oWord.Documents.Open ("C:\TEST.RTF")
	oWord.ActiveDocument.SpellingChecked = False
	oWord.Options.IgnoreUppercase = False
	oWord.ActiveDocument.CheckSpelling

	'Save the changes to the RTF file & close
	oWord.ActiveDocument.Save
	oWord.ActiveDocument.Close
	oWord.Quit

	'Load the changes back to the rtf text box.
	rtfText.LoadFile "C:\TEST.RTF", rtfRTF

	Set oWord = Nothing
	Screen.MousePointer = vbDefault
	MsgBox "Spell Check is complete", _
		vbInformation, "Spell Check"
	Exit Sub

SpellCheckErr:
	MsgBox Err.Description, vbCritical, _
		"Spell Check"
	Set oWord = Nothing
