Can't search through google chrome address bar

If this happens to you, then probably your default search engine is NOT chosen. So all you need to do to click on Setting, Preferences, and then Basic, Default search.

The value of default search should be set as Google(or any other search engine you like).

process all the files under a directory & its sub-directories, C#

public void processDir(string sourceDir, string searchForText, string replaceWithText)
        {
            // Process the list of files found in the directory.
            string[] fileEntries = Directory.GetFiles(sourceDir);
            foreach (string fileName in fileEntries)
            {
                // do something with fileName
                Console.WriteLine(fileName);
            }
            // Recurse into subdirectories of this directory.
            string[] subdirEntries = Directory.GetDirectories(sourceDir);
            foreach (string subdir in subdirEntries)

using Regular Expressions in C# to find a phrase in a text and replace it with another

This is an example on how to find & replace a phrase in a string, the easy way in C# :

            
            using System.Text.RegularExpressions;
            ....
            if (Regex.IsMatch(content, searchText, System.Text.RegularExpressions.RegexOptions.IgnoreCase))
            {
                display.Text += "Found match in " + filePath +" ***\n";
                content = Regex.Replace(content, searchText, replaceText);
            }

Example on how to get a path to work on it later on from folderBrowserDialog in C#

            if (result == DialogResult.OK)
            {
                thePath = folderBrowserDialog1.SelectedPath;
                pathLabel.Text = folderBrowserDialog1.SelectedPath;

Find & Replace requested text in all files application

This small C#.Net application finds & replace the requested text with desired text in all files under one folder & sub-folders. This application was made according to needs of some changes at webpages at work.
The application is under development to be stable enough for release ...

HOWTO, uneditable text box in C#

If you want a uneditable text box, then ReadOnly properties on the text box should be set as True.

Different arrays in C#, Jagged vs. Multi dimensional

Jagged array :
bool[][] myBools = new bool[2][];


Multi dimentional array : 
double[,] myDoubles = new double[2, 2];


One of the differences between jagged arrays and a multi-dimension array is that a multi-dimension array will allocate memory for every element of each dimension, whereas a jagged array will only allocate memory for the size of each array in each dimension that you define. Most of the time, you'll be using multi-dimension arrays, if you need multiple dimensions, and will only use jagged arrays in very special circumstances when you are able to save significant memory by explicitly specifying the sizes of the arrays in each dimension.
