SYMPTOMS
The built-in vbCFRTF constant is incorrectly stored as a long value in Microsoft Visual Basic. It should be stored as an integer. Consequently, if it is used in conjunction with the SetData method of the Clipboard object, that takes an integer parameter to describe format, an Overflow error is generated. This constant is located in the VB - Visual Basic Objects and procedures/ClipboardConstants section of the Microsoft Visual Basic Object Model.



STATUS
Microsoft has confirmed this to be an issue in the Microsoft products listed at the beginning of this article. Microsoft is researching this issue and will post new information here in the Microsoft Knowledge Base as it becomes available.



WORKAROUND
Instead of vbCFRTF, use the value &hBF01. For example, instead of the statement: Clipboard.SetText RichTextBox1.SelRTF, vbCFRTF use: Clipboard.SetText RichTextBox1.SelRTF, &hBF01



Steps to Reproduce Problem
  Start a new project in Visual Basic. Form1 is created by default. Place a RichTextBox control on to Form1. Place the following code in the Click event for Form1: Private Sub Form1_Click Clipboard.Clear Clipboard.SetText RichTextBox1.SelRTF, vbCFRTF End sub   Run the project by pressing F5. Type some text into the RTF control. Highlight the text, click on Form1, and an error is generated:

Run-time error '6'

Overflow

To work around this problem, change the code in the Click event of Form1 to: Private Sub Form1_Click Clipboard.Clear Clipboard.SetText RichTextBox1.SelRTF, &hBF01 End sub
