Q: Converting a string with letters / numbers to hex

[Jon Gunnar Rue]

I have a textbox accepting both numbers and letters. Is there a way to
convert this over to a hex string so I may use it in another textbox ?

I have a textbox accepting both numbers and letters. Is there a way
to convert this over to a hex string so I may use it in another
textbox ?

Like this?

Function GetHexString(ByVal Text As String) As String
Dim i As Integer
Dim sb As New System.Text.StringBuilder
For i = 0 To Text.Length - 1
sb.Append(Asc(Text.Chars(i)).ToString("X2"))
Next
Return sb.ToString

End Function

Note: I assume only ANSI encodable characters are contained (00-FF)
