Windows Batch Files
• Unformatted text file that contains one or more

• Allows you to simplify routine or repetitive tasks.
• When you type the file name at the command
prompt, Cmd.exe runs the commands sequentially
as they appear in the file.

Batch File Parameters
• Cmd.exe provides the batch parameter expansion
variables %0 through %9.
• %0 is replaced by the batch file name.
• %1 through %9 are replaced by the corresponding
arguments that you type at the command line.

< Reads the command input from a file, instead of reading input from the
keyboard.
>> Appends the command output to the end of a file without deleting the
information that is already in the file.
| Reads the output from one command and writes it to the input of
another command. Also known as a pipe.

Batch File Commands

Starting Programs in .NET
• Process class is a useful tool for starting, stopping,
controlling, and monitoring applications
• You can obtain a list of the processes that are
running, or you can start a new process
• After a Process has been initialized, it can be used
to obtain information about the running process
• set of threads
• loaded modules (.dll and .exe files)
• amount of memory the process is using
26 / 58

• The operating system persists the process handle,
which is accessed through the Handle property of
the Process component, even when the process has
exited.
• Thus, you can get the process's administrative
information, such as the ExitCode and
the ExitTime.

// Create new process object.
Process process = new Process();
// Set target file and command-line arguments.
process.StartInfo.FileName = "ParameterDemo.exe";
process.StartInfo.Arguments = "/s";
// Start process.
process.Start();

C#
29 / 58
// Create new process object.
Process process = new Process();
// Set target file. Windows will automatically open the file with the default program.
process.StartInfo.FileName = "textfile.txt";
// Start process.
process.Start();

Assignment #8
1. Title Bar – Map File Name
1. Keep the file stream of the current map file open until
