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.
