Hello, I simply need to execute DOS command from VB.NET code.

This is the code that I run from DOS:

C:\Program Files\omniformat\omniformat.exe "C:\test\test.xls" "PDF"

So, how to execute this same command from VB.NET.

I assume it would use something in this format:
Dim pInfo As New ProcessStartInfo("command/filename", "arguments")
            Dim p As New Process()
            p.StartInfo = pInfo
            p.Start()

but I am not sure what is the correct syntax i.e. what should be my command/filename, and what goes under arguments.

Can someoneprovide me with the code that will work in my situation?
Thanks

Hi,
You can do this with the shell function

Just do it as:
Dim args as String =  chr(34) & "C:\test\test.xls" & chr(34) & " " & chr(34) & "PDF" & chr(34)
System.Diagnostics.Process.Start("C:\Program Files\omniformat\omniformat.exe", args);

If you want to use processstartinfo, you can do this

Dim MyProcess as New Process
Dim psi as New ProcessStartInfo()
psi.FileName="C:\Program Files\omniformat\omniformat.exe"
psi.Arguments="C:\test\test.xls PDF"
MyProcess.ProcessStartInfo=psi
MyProcess.Start()
MyProcess.WaitForExit()

for strings with spaces in them you may need to double ", but not 100% sure.

Dim strTemp as String
Dim iTemp As Integer

strTemp = "C:\Program Files\omniformat\omniformat.exe 'C:\test\test.xls' 'PDF'"
iTemp = Shell(strTemp, AppWinStyle.MinimizedNoFocus)


FYI,

ITemp will be the processid

Other Enumeration value Description
AppWinStyle.Hide
AppWinStyle.NormalFocus
AppWinStyle.MinimizedFocus
AppWinStyle.MaximizedFocus
AppWinStyle.NormalNoFocus  
AppWinStyle.MinimizedNoFocus
