Generate Random Numbers in C#

private static int seed = Environment.TickCount;

// Generate random number tick
private static ThreadLocal<Random> randomWrapper =
            new ThreadLocal<Random>(() => new Random(Interlocked.Increment(ref seed)));
           
randomWrapper.Value.Next(additionMinValue, additionMaxValue);

Reading repetitive XML to memory using C#

Sample XML Document:
<Elements>
    <Element>
        <Name>N1</Name>
        <Type>T1</Type>
        <Color>C1</Color>
    </Element>
    <Element>
        <Name>N2</Name>
        <Type>T2</Type>
        <Color>C2</Color>
    </Element>
    <Element>
        <Name>N3</Name>
        <Type>T3</Type>
        <Color>C3</Color>
    </Element>
</Elements>


Sample C# Code:
XmlDocument myDoc = new XmlDocument()
myDoc.Load(XML_File_Path_Name);

foreach(XmlElement elem in myDoc.SelectNodes("Elements/Element"))
{
    XmlNode nodeName = elem.SelectSingleNode("Name/text()");
    XmlNode nodeType = elem.SelectSingleNode("Type/text()");
    XmlNode nodeColor = elem.SelectSingleNode("Color/text()");

    string name = nodeName!=null ? nodeName.Value : String.Empty;
    string type = nodeType!=null ? nodeType.Value : String.Empty;
    string color = nodeColor!=null ? nodeColor.Value : String.Empty;
} 

Enable remote MySQL connection

Put this as root: GRANT ALL PRIVILEGES ON *.* TO  'USERNAME'@'IP'  IDENTIFIED  BY  'PASSWORD'; where IP is the IP you want to allow acess and USERNAME is the user you use to connect If you want to allow access from any IP just put % instead of your IP and then you only have to put FLUSH PRIVILEGES or restart mysql server and that's it

Trace HTML textbox changes on the fly using JQuery

    function checkTextboxChanged() {
        var currentValue = $('#TextBoxId').val();
        if (currentValue != searchValue) {
            searchValue = currentValue;
            TextboxChanged();
        }
