Inserting String in cursor position Rich text Box

Hi Guys,
How do I add a text stored in a variable into the cursor position?

I know it may be as easy as:

Code:

---

Dim var1 As String = "Text to Insert"

RichTextBox.Cursor.Current = var1

or

RichTextBox1.Text.Insert(RichTextBox.Cursor.Current, var1)

---

Thanks in advance,
Mike

When you say cursor, do you mean the mouse pointer or do you mean the caret, i.e. the blinking vertical bar in the control itself that indicates the insertion position?

I meant the caret, but it's alright
I used

Code:

---


RichTextBox1.SelectedText = var1

---

And it worked.
If there's another and more efficient way can you let me know?

Thanks,
Mike

By complete coincidence I came across this yesterday ...

Get the index of the caret in the TextBox:

C#

int caretIndex = textBox.SelectionStart;
VB.NET

Dim caretIndex As Integer = textBox.SelectionStart
Get the line number from the caret index:

C#

int lineNumber = textBox.GetLineFromCharIndex(caretIndex);
VB.NET

Dim lineNumber As Integer = textBox.GetLineFromCharIndex(caretIndex)
Get the character index in the current line:

C#

Point characterXY = textBox.GetPositionFromCharIndex(caretIndex);
int characterIndex = textBox.GetCharIndexFromPosition(characterXY);
VB.NET

Dim characterXY As Point = textBox.GetPositionFromCharIndex(caretIndex)
Dim characterIndex As Integer = textBox.GetCharIndexFromPosition(characterXY)

That is absolutely the way it should be done. Just note that, if the user has selected some text, that code will replace it. If that's not what you want then you should set the SelectionLength to zero first.

Thanks for the tip.
