richtextbox.lines problem

bfis108137

Hi, First of all I think it's important to point out that my goal here is to create the image of 1 line of vertically centered text like you would find in the windows 7 calculator. My thought was to make 2 lines in the richtextbox, and on the 2nd line I would put the text. However when I do this it just doesn't show. I have checked the font color and it's black. Also multiline is true. Here is my code. Maybe I am missing something.

richTextBox1.Lines = new string[2];
richTextBox1.Lines[1] = 111;

The 111 never appears in the text box and the value of richTextBox1.Lines[1] never even changes.

Hi,

rtb2.Lines=new string\[\] { "line 1", "line 2", "line 3" };

works just fine. You should work out the difference yourself! :)

I changed it to the following code and it worked so I guess I would like to know who I can set the whole array but I can't change individual items within the Lines array. I didn't see that it was read only and anyways if it was it wouldn't compile. To me it doesn't make sense.

richTextBox1.Lines = new string[2] { "", "111111" };

After reading the documentation (you should try that, they really make an effort to explain things), I come up with:

rtb2.Lines=new string\[\] { "line 1", "line 2", "line 3" };
string\[\] lines=rtb2.Lines;
lines\[1\]="new line 2";
rtb2.Lines=lines;

and that works too. BTW: I'm not saying it is the most efficient way under all circumstances... :|

I wonder what the type of 111 might be?

Console.WriteLine(111.GetType().ToString()) gives System.Int32 Pretty obvious, I'd say. :)
