DOS TYPE command from within VB

[Darin]

I need to open a cash drawer and the easiest way to do that is to:

ECHO "||" > LPT1

I have put:

system.diagnost ics.process.sta rt (my echo command)

but it fails with a File Not Found error.

Any ideas???

Echo is a feature of the windows command-line shell ("cmd.exe"). The sample
below will show you how to control "cmd.exe" using a .NET application:

RedirectConsole

Shell worked fine.

I never had any luck using shell with Echo. The redirect Console app saved
me from insanity. I could not get the echo to work via the shell with gpg
commands.

Can you post the working code? 'Shell' does not have any advantage over
'Process' in processing command-line shell commands.

Re: DOS TYPE command from within VB

junk = "ECHO " & Qte(Chr(1) & Chr(1), True) & " > " & Trim(port)
Shell(junk, AppWinStyle.Hid e)

Qte is a routine that will put text in " ", so this is:

ECHO "ctrl-A ctrl-A" > LPT1

Re: DOS TYPE command from within VB

you can use Process.StartIn fo:

Sub Print()
Dim p As Process = New Process
With p.StartInfo
.FileName = "cmd"
.Arguments = "/c echo ""||"">LPT"
.UseShellExecut e = False
.CreateNoWindow = True
End With
p.Start()
End Sub

Re: DOS TYPE command from within VB

Well, I guess I know what you now mean about shell having issues.

SHELL with the ECHO command worked perfectly on my development XP Pro
machine.
Send the program to the csutoemr and they try it on an XP machine (don't
know if it is pro or home) and he gets an error: File not Found.

I will change it to use the Process.StartIn fo and hopefully I won't have
this issue again.

I will let you know.
