CMD line with parameters

Question

Good afternoon,

I'm trying to read a text file which contains a line of text (in this instance it says (UTC-03:00) City of Buenos Aires | Argentina Standard Time) for setting a timezone on a PC. Here is my code

Dim sString As String = Nothing
Using sr As New StreamReader("c:\temp\test.ini")
sString = sr.ReadToEnd()
End Using
Dim sSubString = sString.Substring(sString.LastIndexOf(" | ") + 1)
' MsgBox(sSubString)

 Dim procStartInfo As System.Diagnostics.ProcessStartInfo = New System.Diagnostics.ProcessStartInfo("cmd", "/k" & ("tzutil.exe /s " + sSubString))
 Dim proc As System.Diagnostics.Process = New System.Diagnostics.Process()
 proc.StartInfo = procStartInfo
 proc.Start()

This is what happens when i run the program...

'Argentina' is not recognized as an internal or external command,
operable program or batch file.

C:\Users\Admin\OneDrive\Projects\Timezone\TimeZone\TimeZone\bin\Debug>

Sorry i'm only a beginner at programming. Can anyone assist me at all?

Thanks
Simon

Evening,

Thanks for your answer.

I'm getting closer to it working but can't fathom out the last bit.

Here's my code....

Dim sString As String = Nothing
Using sr As New StreamReader("c:\temp\test.ini")
sString = sr.ReadToEnd()
End Using
Dim sSubString = sString.Substring(sString.LastIndexOf("|") + 1)

    Dim procStartInfo As System.Diagnostics.ProcessStartInfo = New System.Diagnostics.ProcessStartInfo("cmd", "/k" & ("tzutil.exe /s " + """" + sSubString + """"))
    Dim proc As System.Diagnostics.Process = New System.Diagnostics.Process()
    proc.StartInfo = procStartInfo
    proc.Start()

When i run it, i get the following message

TZUTIL: Invalid time zone Montevideo Standard Time.
Use TZUTIL /l for a list of valid time zones.

If i manually type in the command tzutil /s Montevideo Standard Time, i get this

C:\Users\Admin\OneDrive\Projects\Timezone\TimeZone\TimeZone\bin\Debug>tzutil /s montevideo Standard Time
TZUTIL: Invalid number of arguments for /s.
Use TZUTIL /? for a list of valid options.

However, if i type in tzutil /s "Montevideo Standard Time" it runs succesfully!

Therefore, how do i add quote marks either side?

Many thanks and apologies for perhaps an obvious question

Answer 2

You must add double-quotes around the string

For example, if I hard-code your substring with "Argentina Standard Time" :

        sSubString = "Argentina Standard Time"
        Dim procStartInfo As System.Diagnostics.ProcessStartInfo = New System.Diagnostics.ProcessStartInfo("cmd", "/k" & ("tzutil.exe /s """ + sSubString + """"))
        Dim proc As System.Diagnostics.Process = New System.Diagnostics.Process()
        proc.StartInfo = procStartInfo
        proc.Start()

Answer 3

Hi @Simon Scott ,

if i type in tzutil /s "Montevideo Standard Time" it runs succesfully!

Try:

    Dim procStartInfo As System.Diagnostics.ProcessStartInfo =  
            New System.Diagnostics.ProcessStartInfo("cmd", "/k " & ("tzutil.exe /s '" + sSubString + "'"))  

Hope it could be helpful.
