Problem with Printing to a Text box in a Recursive Program

I have a recursive program (using VB.net) and i'm using a textbox as the output. The recursive program is supposed to translate an integer into binary code and the problem is that (because it is recursive) the output statement rewrites over any text that was outputted earlier. For example instead of having "101101" show up, just "1" shows up because the output statement (that prints to the textbox) just rewrites over it every time.

Does anyone know how I can solve this? I'm sure it's probably a simple solution, but I do not have adequate training in VB.net yet. (If it was VB 6, I would of used a picturebox and use the print function). Thanks for any help.

maybe just build a string, and dont output it until its finished being build

strText = strText & "0"

etc.

then when its finished print strText

Convert.ToString does binary:

Code:

Dim theNumber As Integer = 146
        Dim theNumberInBinary As String = Convert.ToString(theNumber, 2)
        Dim theNumberInOctal As String = Convert.ToString(theNumber, 8)
        Dim theNumberInBase16 As String = Convert.ToString(theNumber, 16)
        Dim s As String = String.Format( _
        "The number {0} is {1} in binary, {2} in Octal, and {3} in Hex", _
        theNumber, theNumberInBinary, theNumberInOctal, theNumberInBase16)
        Debug.WriteLine(s)
