  • Import xml to database with high end performance and Audit log- A best Practice

    - by karthik
    Hi, I have to import big xml files to Ms SQL 2005 Database by using C# with high end Performance. Even if any record fails in middle, i have to take next record for process and failed record need to log for audit. I don't want to put insert query with in for loop. Could you please suggest a best way to do this. If I can use bulkcopy methods or Data Adapter update methods- Its very nice, But if any record fails, execution of that statement breaks and rolled back totally, right? Any alternatives and Best practices with example please..? Is Multi-threading works for me to improve performance..? Give me example please. Thanks Karthikeyan

  • IIS Browser caching not working

    - by Karthik
    Hi, I have enabled caching in IIS 6 for all our static images and CSS(by right clicking on those folders in IIS and enabled Content Expiration after 30 days under HTTP Headers). When I run Google PageSpeed, and look at the resources tab, the status of those images and css shows up as 200, but I was expecting a 304(not modified). When I checked Yahoo.com in Pagespeed, all its images have a 304 status. So my caching is not working? or is this how IIS content expiration works. Any help would be appreciated.

  • Query to MySQL from c# returns System.Byte[]

    - by karthik
    I am using the below SP to return the value of Generated Insert statement and it works fine when executed in Query browser. When i try to get the value from C#, it give's me "System.Byte[]" as return value. When i try to get the value from MySql query browser, it give's me return value as : 'insert into admindb.accounts values("54321","2","karthik2","karthik2","1");' I guess the problem is with the single quotes of the returned value.

  • Thread to receive the messages from serial port is not working using c#

    - by karthik
    I am using Serial port to receive the messages. The below function is running in a thread. When i debug i find that the thread is running properly. But "if (sp.IsOpen)" is always false, due to which the code is not executing inside the IF condition at all. It says the Port is closed. I will be having multiple serial ports in my system and i will not know, which port will receive the message. So i need to listen to all the ports in one Thread. How can i solve my problem here ? private void ListenerPorts() { log.Info("Listening Thread Started"); while (true) { //foreach (SerialPort sp in storeport) foreach (SerialPort sp in comPortsList) { if (sp.IsOpen) { sp.ReadTimeout = readTimeoutInMs; sp.WriteTimeout = writeTimeoutInMs; try { string msg = sp.ReadLine(); this.GetMessageRichTextBox("Message : " + msg + "\n"); sp.WriteLine(sp.PortName); if (msg.Contains("COM")) { // is AutoScan receiverPortName = sp.ReadLine(); this.updateLblStatusRichTextBox(sp.PortName + " is connected to " + msg + "\n"); } else { //standalone is uppercase ReceiverPortName = sp.ReadLine(); this.updateLblStatusRichTextBox(sp.PortName + " is connected to " + ReceiverPortName + "\n"); } } catch (Exception ex) { // no data System.Diagnostics.Debug.WriteLine(sp.PortName + " : " + ex.Message); } } } } }
