title: How to convert from decimal to binary .NET
body: <p>I'm a bit confused on decimal to binary number conversion. Here's my code:</p>
  
  <pre><code>Public Class Form1
  
      Private Sub tbxDecimal_TextChanged(sender As Object, e As EventArgs) Handles tbxDecimal.TextChanged
  
          If rdbDecmial.Checked = True And IsNumeric(tbxDecimal.Text) Then
              Dim bin, dec As Double
              Dim output As String
              dec = Convert.ToDouble(tbxDecimal.Text)
              For i = 1 To dec Step (???)
                  dec = i Mod 2
                  If i Mod 2 = 0 Then
                      bin = 0
                  Else
                      bin = 1
                  End If
                  output &amp;= Convert.ToString(bin)
              Next
              tbxBinary.Text = output
          End If
      End Sub
  End Class
  </code></pre>
  
  <p>If I typed in a decimal number in one box, the incorrect numbers come out. I know I have to have some kind of stepping size for this loop, however what should I put in?</p>
