IP textbox

[Nazgulled]

Is it possible to have a textbox to act like the ones in the network connections in the TCP/IP properties? how?

The .NetFramework 2.0 has a masked textbox control which allows you to set a mask for input. You also need to verify the values entered, making sure that each number is less than 256.

thanks... however, i'm having difficulties to convert the string of the masked textbox to int to see if it's less than 256...

 

Private Sub mtxtLIP_KeyUp(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles mtxtLIP.KeyUp
       Dim segments As String() = mtxtLIP.Text.Split(".")
       Dim segment As String

       For Each segment In segments
           If segment > 255 Then
               picLIP.Visible = True
           Else
               picLIP.Visible = False
           End If
       Next
   End Sub

 

Obviously, this doesn't work... but I tried many int conversions and none of them worked...

If int.Parse(segment) > 255 Then

*NB it sounds like your using .Net 2.0 in which case you could use TryParse(), if you do however note the overload is different to Parse()

Just to add my own 2 pence worth...

 

When using VB I would always recommend putting Option Strict On at the top of every source file. In fact I would make this the default under Tools->Options->Projects And Solutions->VB Defaults

If int.Parse(segment) > 255 Then

That didn't work, nor Integer.parse() I had to solve it with the tryparse()

 

thanks...

 

I thought I had option strict on but I guess I was wrong. If I enable it globally in the options, I'll still have to add it to my program right? Unless I start to create a new project... right or wrong?

Thats my fault int is a C# type. Perhaps Single.Parse() would have worked better.

I did a google search for "IP Address textbox c#" without the quotes and came up with the following:

He address a LOT more issues that you were/are probably interested in, but still might prove useful. Glad to see you got the parsing fixed. :)

 

Note: I didn't actually look in detail at what was posted so I'm not saying it's definitely an example of clean code. Just thought I'd offer up the link in case it happens to work for you.
