I failed a bit before when I asked for help... here is JF2015 code:

string strInsertBefore = "<a>";
string strInsertAfter = "</a>";

string text = textBox4.Text.Substring(textBox4.SelectionStart, textBox4.SelectionLength);
text = strInsertBefore + text + strInsertAfter;

and I add this:

textBox4.Text = textBox4.Text.Insert(textBox4.SelectionStart, text);

this results in

<a>hello</a>hello

when I mark 'hello'. Do you know why I get double 'hello'?

do not repost a question. If you want to add some thing, you can add it to the previous one.

Solution 1

Because you are inserting the text into the existing text, rather than replacing the old text with the new text.

Try

C#

textBox4.Text.Insert(textBox4.SelectionStart, strInsertBefore);
textBox4.Text.Insert(textBox4.SelectionStart + textBox4.SelectionLength - 1, strInsertAfter);

instead
