Newbie KeyPress question... [RESOLVED]

[milkmood]

This is so elementary, I know. I want to simply move to the next TabStop with the press of the period key (like in an IP configuration dialog). I think I need the use the KeyPress event, but I'm not sure. Should be like, one line of code. I would also like to do the same when MaxLength is reached, but that's less important.

Thanks,
CP

yes keypress would be fine. when the keypress event fires, use the event arguments that are passed in (as e) to determine if a "." was pressed. That should get you started, post back if you get stuck

Like I said, total newbie. Some sample code would be very helpful. The next field is the next tabstop, of course. ConfIP01 is a textbox, as is ConfIP02, 03, and 04, followed by a port textbox.

Private Sub ConfIP01_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles ConfIP01.KeyPress
 
End Sub

Thanks.

here you go.. you owe me a cookie

Private Sub CheckForPeriod(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles txtIP1.KeyPress, txtIP2.KeyPress, txtIP3.KeyPress, txtIP4.KeyPress
        'CHECK FOR A "."
        If e.KeyChar = "."c Then
            'SET HANDLED TO TRUE SO THE "." IS NOT PROCESSED
            e.Handled = True
            'SEND THE TAB KEY TO GO TO THE NEXT CONTROL
            Me.ProcessTabKey(True)
        End If
    End Sub

you will notice this routine does the following
1) checks for a . being entered in any of the 4 IP boxes (notice this routine HANDLES 4 different keypress events - one from each IP box)
2) sets handled to true so a . doesn't come up in the textbox
3) sends a tab keypress to the form which will send focus to the next item in the taborder

That's what I needed...someone to hold my hand. Thanks a lot. Sending cookie now.

After I decided to do it this way, I realized 2 things. (1) I'll have to add the periods in in the code, and (2) there's no way to look for a machine name using the 4 IP boxes...SO, I'm going to just use a textbox. It's a configuration that will probably only be used once. It's to connect to a database within the network. After that, it will keep the connection (not persistent, but keep the settings).

Thanks again,
CP

you can still use 4 seperate boxes. just concatenate them together and add the '.' between each:

visual basic code:


dim ip as new stringbuilder
ip.append(textbox1.text)
ip.append(".")
ip.append(textbox2.text)
ip.append(".")
ip.append(textbox3.text)
ip.append(".")
ip.append(textbox4.text)

ip.tostring

[milkmood]

I may do that and use a separate box to look for the machine by name.

Thanks,
