I am trying to run MS dos call command from a C# form.

[Bruce Hutton]

The call command runs a program called m4dc.cmd

The actual code is.
call c:muller\mucam\ cam_cli\m4dc.cm d C:\MULLER\MUCAM \conver\%1.ep

How can I run this call cammand in a C# form application?

The call comand calls the m4dc.cmd program and I think points to the address C:\MULLER|MUCAM |convert\%1.ep
and waits until the the new upt file has been created
It takes the ep file stored at the above location and converts the ep file to a upt file.
I hope you can help with this.
Thanks
Bruce

DOS or the console?

[Bruce Hutton]

Dos
The C# program has to run the MS DOS call commad

[Aimee Bailey]

how about this?:

Process.Start("call c:muller\mucam\cam_cli\m4dc.cmd C:\MULLER\MUCAM\conver\%1.ep");

Thanks Aimee
I tried this first of all but it didn't work. I think the problem is with the call parameter C:\Muller\MUCAM \convert\%1.ep.
I think it also need to use \\ between the directories. eg
C:\\Muller\\MUC AM\\convert\\%1 .ep
My code is

System.Diagnost ics.Process.Sta rt("call C:\\muller\\muc am\\cam_cli\\m4 dc.cmd C:\\MULLER\\MUC AM\\convert\\%1 .ep");
Do you know if Process.Start will work with the call paramenter?

Thanks very much for your help

[Aimee Bailey]

you could try...

System.Diagnostics.Process.Start("call \"C:\\muller\\mucam\\cam_cli\\m4dc.cmd\" \"C:\\MULLER\\MUCAM\\convert\\%1.ep\"");

that's using escape params.

How do you get the value for that %1? My only knowledge of that syntax is when making batch files, the %1 (%2, %3, ...) are the parameters to a batch file. Your program would get that parameter in a different way, wouldn't it?

Unless there's something else I don't know about (quite likely, I admit), you'll need to insert the parameter into your string...

public void PerformCall(string param)
{
  string callText = string.Format(
    "call \"C:\\muller\\mucam\\cam_cli\\m4dc.cmd\" \"C:\\MULLER\\MUCAM\\convert\\{0}.ep\"",
    param);

  System.Diagnostics.Process.Start(callText);
}

Is that what you were looking for, or am I way out to lunch?

I think gary is on the money :)

Thanks Aimee and Gary
Sorry I didn't get back to you but the time difference in Aust is a problem.
I will try both of your suggestions but I have to send the code to the UK to try. I tied similar code to Gary's using StartIfno but didn't work. I will give both yours suggestions ago and get back to you.

Thanks very much for your help. I can write a batch file with the MS Dos call function in it and stat that with Process.Start() ; and I am sure that will work. But I would like to have the complete code in C#.NET if I could. I have programed in C, C++ C++.NET and C# for over 20 years this is just tricking me.

Sorry Gary
I didn't answer question on %1. This is a EP file my code produces and stores it in C:\MULLER|MUCAM |convert\
The actual call MSDOs function is part of another batch file that works OK but it just run as a batch file. The problem is to get the call function to work from a C# Form appliction.
