Clipboard Access + IIS6.0 + Win2003

Hi Tom

I am using the following Statement
System.Windows.Forms.IDataObject temp =
System.Windows.Forms.Clipboard.GetDataObject();

I get the Exception The Clipboard operation failed
The function that contains the statement runs under a STA thread.

My web service code does the following
based on a document id, RTF content is fetched from the database.
A word document is created.
The RTF content is set to the Clipboard using the IDataObject retrieved
using the statement System.Windows.Forms.Clipboard.GetDataObject();

then using this statement
p_oTempWordDoc.Range(ref l_oMissing,ref l_oMissing).Paste the rtf content is
pasted to the word document. this document is saved and then sent to the
client (that is the URL to the document)

This is the statement that fails
System.Windows.Forms.Clipboard.GetDataObject();
It same code works correctly on Win2k server with IIS5.0 Wonder what could
be the reason for not working in WIN2K3 and IIS6

Thanks

I'm not familiar with using the Clipboard object and frankly (even though it
worked on IIS5) it doesn't seem like something suited to a web
app/server-side code.

Hi Prasanna

I had the same problem and have a solution, which does not use the
clipboard. Simply write your RTF text to a text file saved with a .rtf
extension. Then use the Selection.InsertFile method of the word
automation object. All your RTF formatting is retained as Word will
take care of the rtf decoding - presumably the reason for wanting to
use the clipboard in the first place.

Code extract:
//Sample rtf
string oSubText="{\rtf1\ansi\ansicpg1252\uc1\deff0\stshfdbch0\stshfloch0\stshfhich0\stshfbi0\deflang1033\deflangfe1033{\fonttbl{\f0\froman\fcharset0\fprq2{\*\panose
02020603050405020304}Times New
Roman;}{\f35\fswiss\fcharset0\fprq2{\*\panose
020b0604030504040204}Verdana;}";

string sRTFFile=@"c:\test\insrtf.rtf"
SaveToTextFile(sRTFFile,oSubText,false);
//using word automation

Range range = oRange;
//Find tag to replace
range.Find.Execute(ref oFindText,
ref m_oMissing, ref m_oMissing, ref m_oMissing, ref m_oMissing, ref
m_oMissing,
ref m_oMissing, ref m_oWrap, ref m_oMissing, ref m_oMissing, ref
m_oMissing,
ref m_oMissing, ref m_oMissing, ref m_oMissing, ref m_oMissing);

m_oWord.Selection.Start = range.Start;
m_oWord.Selection.End = range.End;

//Insert RTF from file
m_oWord.Selection.InsertFile(sRTFFile,ref m_oMissing, ref
m_oMissing,ref oMissing, ref m_oMissing);

//Simple string to file function
public void SaveToTextFile(string sFile, string sOut,bool bAppend)
{
FileStream s;
StreamWriter w;
int i;
if(bAppend)
s = new FileStream(sFile,FileMode.Append);
else
s = new FileStream(sFile,FileMode.Create);
   
w = new StreamWriter(s);
w.Write(sOut);
w.Close();
}

Hope this helps you. Annoyingly this problem only ocurred on certain
machines and frankly I don't have the time to figure it out. The old
addage applies: "If it hurts stop doing it", so forget the clipboard
for now. It hurts too much!
