大家好，

Hello all,
I have written a code that returns the rtf of rich text box then i save it in ms access memo field. now i am reetrieving this rtf and want to display it into rich text box .but its saying file format is not valid .I am using following code: how to display it

string[] strQ = splitterPart(rtbQuestion.Rtf.ToString(), 50000);
if (strQ.Length == 1)
{
    string sqlcommand = "update Questions set Questions.Question ='" + 
                        rtbQuestion.Rtf.Replace("'", "''") + 
                        "' where Questions.QuestionNo=" + 
                        Convert.ToInt32(Qno.Text) + ";";
    DbOperation.InsertOrUpdateQuery(sqlcommand, Myconn);
}
else
{
    for (int iIndex = 0; iIndex < strQ.Length - 1; iIndex++)
    {
        // Question rtbQuestion.Rtf.Replace("'", "''")
        Sqlcommand = "";
        Sqlcommand = " update questions set Questions.Question = '" + 
                     strQ[iIndex].Replace("'", "''") + 
                     "' where Questions.QuestionNo="; + 
                     Convert.ToInt32(Qno.Text) + 
                     ";";
        DbOperation.InsertOrUpdateQuery(Sqlcommand, Myconn);
    }
}

private string[] splitterPart(string strSource, int size)
{
    int arrSZ = strSource.Length / size;
    string[] result = new string[arrSZ + 1];
    int jStartIdx = 0, jEndIdx = size - 1;
    for (int i = 0; i <= arrSZ && jEndIdx < strSource.Length; i++)
    {
        result[i] = strSource.Substring(jStartIdx, size);
        jStartIdx = jEndIdx + 1;
        jEndIdx = jEndIdx + size - 1;
    }
    if (jStartIdx - 1 < strSource.Length)
    {
    }
    return result;
}
