Hi All,

I have a web app in which there is button click function which is executed multiple times even on single click. Its a issue of multiple threads running problem.Main thread runs first and after that 2 or 3 times code executes which gives unnecessary errors.

Please advice any solution.

Or any idea about how to allow main thread execution and stops other threads being executing.

Thanks in advance.

this is the code now tell me wat else u want..

if(sFunctionToCall != "")
{
    //bReturnStatus = CallCWSFunctionNoBind(sFunctionToCall, out sCWSresponse, m_objMessageElement);
    //igupta3 Mits : 28566 To restrict duplicate requests while print checks. PageLoad() is called twice.
    if ((sFunctionToCall != "PrintChecksAdaptor.UpdateStatusForPrintedChecks") || (sFunctionToCall == "PrintChecksAdaptor.UpdateStatusForPrintedChecks" && this.hdnRequest.Value != "START"))
    {
        this.hdnRequest.Value = "START";

        bReturnStatus = CallCWS(sFunctionToCall, m_objMessageElement, out sCWSresponse, false, true);
        if (sFunctionToCall == "PrintChecksAdaptor.PostCheckDetail" || sFunctionToCall == "PrintChecksAdaptor.PostCheckSummary" || sFunctionToCall == "PrintChecksAdaptor.PostCheckSubAccount")
        {
            objTempElement = XElement.Parse(sCWSresponse);
            objTempElement = objTempElement.XPathSelectElement("./Document/PrintChecks/File");
            //TextBox txtPdfFile = (TextBox)this.Form.FindControl("File");

        byte[] pdfbytes = Convert.FromBase64String(objTempElement.Value);

        Response.Buffer = true;
        Response.Clear();

        Response.AddHeader("Accept-Ranges", "bytes");
        Response.BinaryWrite(pdfbytes);
        Response.Flush();
        Response.Close();
    } // if
        //igupta3 Mits : 28566 Changes starts
        string TemError = String.Empty;
        XmlDocument usersXDocTemp = new XmlDocument();

            lblError.Text = usersXDocTemp.SelectSingleNode("//WorklossError").InnerText;
        }

    }
} // if
