vb.net 2010 System Tray Icon and Popup Menu

[Steve21]

Ok full code enclosed (Not sure where you'll try to run it from but I'm in N drive so it might emo, but you can view form1.vb as it's all in there anyway even if project wont run)

WindowsApplication2.zip

(From Scratch)
Step 1:
Add ContextMenu and NotifyIcon from Toolbox (I left as default names)

Step 2:
In form load, Link Notifyicon to the menu (so when you right click it it appears near etc)

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        NotifyIcon1.ContextMenuStrip = ContextMenuStrip1
        'Links menu to the Icon (aka, why yours was miles away)
    End Sub

Step 3:
Link event of clicking Icon to menu showing

  Private Sub NotifyIcon1_MouseClick(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles NotifyIcon1.MouseClick
        If e.Button = MouseButtons.Right Then NotifyIcon1.ContextMenuStrip.Show()
        'Shows menu when Icon right clicked
    End Sub

Step 4:
Add menu items (Click on contextmenu item on form design page), Right click and edit items (add menu items)

Step 5:
Link commands/subs to clicks

    Private Sub InfoMenu_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles InfoMenu.Click
        MsgBox("You clicked Info")
        'When Info clicked
    End Sub

If the default project works ignore my waffle But I know when I tried it at home, it emo'd as my home pc is C:\ (obviously) and work one is N:\ :P

Any problems shout etc,

(ps, off topic but anyone knows how to disable quotes popping up as huge AMG ALERTS on edugeek?)

If the above exe is uploaded inc source code The context menu works correctly so Id like that chunk of source, what you did etc, the minimizing the form is wrong but I can easily enough fix that.

Because I am using system.net.dns to get ip address / hostname etc, how does that work if say its a laptop which is physically connected ( ethernet cable ) and also by wireless G or N ??

This is the code I use in HAP+ to get the IP address(es)

                foreach (IPAddress ip in Dns.GetHostEntry(Dns.GetHostName()).AddressList)
                    if (ip.ToString().Contains(".")) { ip1 = ip.ToString(); break; }

[nickbro]

Put .ToString() at the end

Also check out MSDN to find out what Properties you can use of them

                foreach (IPAddress ip in Dns.GetHostEntry(Dns.GetHostName()).AddressList)
                    if (ip.ToString().Contains(".")) { ip1 = ip.ToString(); break; }

VB

For Each ip As IPAddress In Dns.GetHostEntry(Dns.GetHostName()).AddressList    
       If ip.ToString().Contains(".") Then
            ip1 = ip.ToString()
            Exit For     
       End If 
Next

what is the safest method of logging off, I used to use WMI but you are stating that this is a messy method / means of logging off.

The only other way is to use the process.start() method and to use the shutdown with relevant switches or rundll ??

This is what I have so far, waiting on confirmation on the best method to log off but as far as the form is concerned ( might be messy ) but functionality assuming it does the same as what it did when I was running it, seems to work, obviously buggy

WMI is fine, there are some buggy versions etc, but lots of programs use it with no issues.

Btw, There's a much easier method of username if you're intested.

ENVIRONMENT.USERNAME works fine assuming it's run as user, and not service/domain account etc. No imports etc, but only an idea :P Both ways work end of day.

Other log off options:

(Start process as you mentioned) System.Diagnostics.Process.Start("shutdown", "-l -t 00") (Can have issues based on OS etc)
(Windows API) ExitWindowsEx(EWX_LogOff, 0&) (May need premissions) e.g. ExitWindows(RestartOptions.LogOff, True)
Shell commands (Similar to the processes)
Win32Shutdown Method (But if you don't want WMI, can't really use)


Personally WMI is wonderful, and works for many many MANY things. Shouldn't discount it so quickly, but then opinions I guess :P End of day, Pick one you like, understand and makes it easier for you!
