Syntax Highlighting
Well, as you may have seen I've implemented Syntax Highlighting into my latest CoD program. You're also probably wondering how in the hell I did it.
It was actually pretty easy. I just used Regex (Regular Expressions) to color co-ordinate the keywords.
Step 1:
Step 2:
You must login or register to view this content.
Double click you're Timer, and add the following code:
You must login or register to view this content.
//Get the last cursor position in the richTextBox1.
int selPos = richTextBox1.SelectionStart;
//For each match from the Regex, highlight the word.
foreach (Match keyWordMatch in varNameHere.Matches(richTextBox1.Text))
{
richTextBox1.Select(keyWordMatch.Index, keyWordMatch.Length);
//The color of the highlighted text is Blue.
richTextBox1.SelectionColor = Color.Blue;
//This just keeps the program from highlighting the words after the one you want, from being highlighted.
richTextBox1.SelectionStart = selPos;
richTextBox1.SelectionColor = Color.Black;
}
While still in the code viewer, scroll up until you see this:
You must login or register to view this content.
public partial class mainForm : Form
{
NOTE: There isn't a closing bracket so, don't try and add one.
Then add this in:
public Regex varNameHere = new Regex("words|to|be|highlighted|in|this|color");
"varNameHere" can be anything at all.
That's it! Hope you enjoy!

Still using the less efficient timer method? Remember what I posted like a few weeks ago on TTR?
You must login or register to view this content. .... That way it only runs Regex when you need it to, plus the Regex itself is more accurate, plus it prevents the screen from flashing each time it updates.
