Hi.
I want to get rtf to my FreeTextBox(ftb instance in code below). So I copy
.rtf to clipboard, and now I want to paste it from clipboard to ftb. But I
got error 'Object reference not set to an instance of an object.'
Here's my code:
--
System.Windows.Forms.RichTextBox MyRTF = new
System.Windows.Forms.RichTextBox();
MyRTF.LoadFile("e:\\projects\\iso\\hmm\\h.rtf");
MyRTF.SelectAll();
MyRTF.Copy();
System.Windows.Forms.IDataObject data =
System.Windows.Forms.Clipboard.GetDataObject();
if (data.GetDataPresent(System.Windows.Forms.DataFormats.Rtf))
{
ftb.Text = data.GetData(System.Windows.Forms.DataFormats.Rtf).ToString();
}
--------------
Here is error:
--
Object reference not set to an instance of an object.
Description: An unhandled exception occurred during the execution of the
current web request. Please review the stack trace for more information
about the error and where it originated in the code.
Exception Details: System.NullReferenceException: Object reference not set

Source Error:
Line 67: ftb.ToolbarLayout = "Paste";
Line 68: System.Windows.Forms.IDataObject data =
System.Windows.Forms.Clipboard.GetDataObject();
Line 69: if (data.GetDataPresent(System.Windows.Forms.DataFormats.Rtf))
Line 70: {
Line 71: ftb.Text =
data.GetData(System.Windows.Forms.DataFormats.Rtf).ToString();
==============================
Thanks for help.
