Inserting into a text box at the cursor on button

[jomachi]

Have put some code in that allows a site administrator to upload an image. I would like to modify the button click subroutine so that it will insert the <img src=http://aspmessageboard.com/archive/index.php/"...." /> code for the uploaded image at the point where the cursor is in a text box:<BR><BR>================================================== =========<BR> Sub Upload_Click(ByVal sender As Object, ByVal e As EventArgs)<BR> <BR> Dim strFileName As String<BR> <BR> ' Proceed only if a file has been specified<BR> strFileName = System.IO.Path.GetFileName(UploadedFile.PostedFile .FileName)<BR> UploadedFile.PostedFile.SaveAs(Server.MapPath("/Portal/images/") + strFileName)<BR> <BR> End Sub<BR>================================================== =========<BR><BR>How's it done????<BR><BR>cheers,<BR><BR>si
