Inserting datetime in a rich text box

Question

Greetings. I'm very much a newbie at C#. I've taken a couple of online classes, but I still have very much to learn. I'm developing a small word processor application (just to see if i can do it, and for my own use when it's finished) and I need to know how to insert the DateTime object into a rich text box wherever the cursor happens to be at the time, just like it works in Wordpad. This kind of code is beyond my current understanding. I have most of the functionality of what a typical user would expect from a word processor working reasonably well, but I would love to have this function as part of my program. Thanks for whatever help you can provide and for your time.

c# is great language :P so I must help you so you continue with learning it.. ;p
followint line of code hapens when you press button1.. you can modity it for your own uses..
private void button1_Click(object sender, EventArgs e)
{
int CaretPosition = richTextBox1.SelectionStart;
string TextBefore = richTextBox1.Text.Substring(0, CaretPosition);
string textAfter = richTextBox1.Text.Substring(CaretPosition);
string currentDate = " "+DateTime.Now.ToString("dd-MM-yyyy")+" "; // " " = blank space, so there is blank space before date, and after.. you can remove if you want..
//allso you can insert time if you want modigy ("dd-MM-yyyy hh:mm:ss").. and you allso have date and time..
richTextBox1.Text = TextBefore + currentDate + textAfter;
}

Thank You very much Aleksander. I now have it working. I took a portion of what you wrote and used it and Voila , I now have a working dateTime option. I already had the following:
DateTime myTime = new DateTime();
myTime = DateTime.Now;
string wDateTime = " ";
wDateTime = myTime.ToString("g");
And then using what you gave me, I finished it with:
int CaretPosition = rtbMain.SelectionStart;
string TextBefore = rtbMain.Text.Substring(0, CaretPosition);
string textAfter = rtbMain.Text.Substring(CaretPosition);
rtbMain.Text = TextBefore + wDateTime + textAfter;
I never realized it would be that simple. I had nightmarish visions of having to go into the cursor class and computing the X & Y axis positions. I'm sure glad I didn't have to do that. Once again, thank you. I appreciate your help!
