How to get the computer name from other computer where my program installed?

I have a shared program from other PC. I want to display into textbox the computer name from other PC where my shared program installed.
Using "application.startup" the vb can detect where the program came from. Yes it displays the path (e.g. \\PC1\sampleprogram\) but I want to get or to display "PC1" into textbox. Any suggestion or modification regarding my code?

What I have tried:

First try but not working:

Hide Copy Code
txtServerName.Text = System.Net.Dns.GetHostName(Application.StartupPath)


Second try:

Hide Copy Code
txtServerName.Text = System.Environment.GetEnvironmentVariable("ComputerName"(Application.StartupPath))


All are not working. It shows error "Additional information: Conversion from string "C:\Users\r0n\Documents\Visual St" to type 'Integer' is not valid."

try one of these...

Code:

---

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

        Dim UserMachine As Microsoft.Win32.RegistryKey
        Label1.Text = Microsoft.Win32.Registry.CurrentUser.Name.ToString
        Label2.Text = Environment.UserName.ToString()
        Label3.Text = SystemInformation.UserName
        Label4.Text = System.Security.Principal.WindowsIdentity.GetCurrent().Name

        '... Windows Forms-'SystemInformation.UserName',
        'or 'System.Security.Principal.WindowsIdentity.GetCurrent().Name'.
    End Sub

If Application.Startup displays the server accurately, then it seems to me the simpest solution is to first remove the leading "\" and then split on the "" and take the first element in the resulting array.

Firstly, does Environment.MachineName not work? Secondly, if you already have "\\PC1\sampleprogram" then how hard can it be to get the "PC1" part out of that? The Path class may be able to do it, although I've never tried with a UNC path, but you could easily do it with IndexOf and Substring.

Wouldn't that return the current computer name though? Not the name of the server where they are running the app from. Or am I mistaken on that?
