In VB6 we used to have a property called OLEObjects on RichTextBox.
I used it to make my richTextbox not accept OLE objects when user tries to
paste.
Code something like following:

I have a record displayed in datagrid and 2 columns says the text i've
designated as the nulltext for those columns, but when i look at the data in
