Questions about ProcessStartInfo

[Academia]

I use:

'Execute Command (DOS) commands

Dim StartInfo As New ProcessStartInf o

Static sMyProcess As New Process

StartInfo.FileN ame = "cmd"

....



1) Is there another file that runs DOS commands in XP besides cmd?

Does the XP Command prompt window use cmd or something else?



2)The @ doesn't appear to work for me. I use:

SWIn.WriteLine( "@echo off")

but the command shows in the output. I believe the @ should suppress the
listing of the command in the output.



Thanks for any help

RE: Questions about ProcessStartInf o

1. I don't think there is any other command for cmd.exe...
2. @ is a batch symbol which only applies to batch files, or interactive
cmd.exe. Your process is running cmd.exe with commands (I suspect), and not
running a batch where @ applies.

2. @ is a batch symbol which only applies to batch files, or interactive

cmd.exe. Your process is running cmd.exe with commands (I suspect), and not
running a batch where @ applies.

If this is the case you could first create the batch file with the
necessary commands and then use the Process class to execute the batch
file. Just be sure to make sure your application has adequate
permission to do so on the client machine.

Re: Questions about ProcessStartInf o


All I want to do is change the prompt without echo.
Is there some way (without using a batch file) that I could effectively
do.
sMyProcess.Star tInfo = StartInfo

sMyProcess.Star t()

Dim SWIn As System.IO.Strea mWriter = sMyProcess.Stan dardInput

SWIn.WriteLine( "@prompt $G")

....

Maybe an argument??

Thanks

Re: Questions about ProcessStartInf o

I believe you would need to change the environment variable for the PROMPT,
then use that environment for the process.start. I don't think a command
argument for cmd.exe exists for this.

How about this:

///////////////////////
'// Thanks to Wikipedia for giving me this
'// simple batch file

Dim filePath As String = "C:\MyFile. bat"

Using sw As New StreamWriter(fi lePath, False)
sw.WriteLine("@ echo off")
sw.WriteLine("e cho Hello, World!")
sw.WriteLine("p ause nul")
End Using

Dim p As Process = Process.Start(f ilePath)

p.WaitForExit(2 500)

File.Delete(fil ePath)
//////////////////////
