How to turn an integer into a binary string?

How can I WITHOUT USING THE VB COMPABILITY NAMESPACE get it's binary representation? For example : 3021 would turn into 101111001101

tks :D

Hi.

Something like this, should do it.
This uses a 16 bit value, hence the value of 15, but you can just as well use 31 instead of 15 to use a 32 bit value.

VB Code:

Dim S as String
Dim I as Integer
 
For I=15 To 0 Step -1
  If (Value And 2^I)=2^I Then
    S &= "1"
  Else
    S &= "0"
  End If
Next

I posted a function in this thread that converts signed long integers. Not sure what you'd need to do to modify it for .NET though.

VB Code:

Dim val() As Integer = {1}
 
        Dim x As New BitArray(val)
        Dim strOut As String
 
        For i As Integer = 0 To x.Count - 1
            strOut &= IIf(x.Item(i), "1", "0")
        Next
 
        Debug.WriteLine(StrReverse(strOut))

PT Exorcist, is this related to your thread where 4635 = 18,27? If so, you don't need to go through all that trouble

VB Code:

Dim port As Integer = 4635
        MessageBox.Show(Decimal.Truncate(port / 256))
        MessageBox.Show(port Mod 256)

You rule so much :D Ill try it now.
