i have a function in a module that requries integer values. these values are set by the user typing in two textboxes on the form. the texboxes contain Hexadecimal data in string form.


Friend Function addNewCode(ByVal Location As Integer, ByVal Opcode As Integer) As Boolean

    If (Not LocStack.Count < 1000) Then
        Form1.TextBox1.AppendText("Cannot add new code. No room Left in queue!")
        Return False
        Form1.TextBox1.AppendText("Added New Code " & Hex(Location) & "-" & Hex(Opcode) & " in queue slot " & LocStack.Count - 1 & "!")
    End If

    Return True

End Function

and is called when a button is pressed on the form:

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
    addNewCode(Convert.ToInt32(TextBox1.Text, 16), Convert.ToInt32(TextBox3.Text, 16))
End Sub

However when the button is clicked, the program throws the following:

FormatException: cannot find recognizable digits

any ideas?

As long as the first argument is a string representation of a hex value this will work. In the general case, the first argument is a string and the second argument is the base so you could also use this to convert other bases such as


which would convert 203 octal to base 10.
