.rtf->clipboard->FreeTextBox

[Markusek Peter]

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.RichTextB ox MyRTF = new
System.Windows. Forms.RichTextB ox();
MyRTF.LoadFile( "e:\\projects\\ iso\\hmm\\h.rtf ");

MyRTF.SelectAll ();

MyRTF.Copy();

System.Windows. Forms.IDataObje ct data =
System.Windows. Forms.Clipboard .GetDataObject( );

if (data.GetDataPr esent(System.Wi ndows.Forms.Dat aFormats.Rtf))

{

ftb.Text = data.GetData(Sy stem.Windows.Fo rms.DataFormats .Rtf).ToString( );

}

--------------

Here is error:

--

Object reference not set to an instance of an object.

Hi Peter,

I am feeling pretty confident this is caused by the ASPNET user account not
having enough access priviledges to access the windows clipboard. (Also I
wouldn't recommend using System.Windows. Forms namespace in web applications)
The reason I believe this, it that the part of your code that chokes is the
'data' variable - it isn't instantiated (most likely it results in NULL).

What does this question have to do with ASP.Net? Every reference in it is to
Windows Forms.

Hint: "FreeTextBo x" - although I have to admit I was thrown off at first
myself, but I understand what he is trying to accomplish and replied to
him...
