Shell
We're trying to run a batch file using the shell command. Can anyone give us the code to do this? We've tried the shell command that is given in the MSDN help file but we're getting errors.
Cheers,
Luke

If you're trying to launch another program from your program, VC++ has several methods for doing this.
_spawn(), _exec(), system(), WinExec(), ShellExecute(), ShellExecuteEx(), and CreateProcess()
For more information, see following link:

The CreateProcess() functions gives you the most control, but it's a bit tricky to use.
In the above link, there's a wrapper class for CreateProcess() function. The wrapper class is called CreateProcessMngr

the system("program.bat") call is the best way to it.
your executable must to be in the same directory of the batch file or you must to put the location to the batch file.
system("c:\bach_files\prog
include file : process.h
prototipe: int system( const char *command );
"Return Value
If command is NULL and the command interpreter is found, the function returns a nonzero value. If the command interpreter is not found, it returns 0 and sets errno to ENOENT. If command is not NULL, system returns the value that is returned by the command interpreter. It returns the value 0 only if the command interpreter returns the value 0. A return value of ? 1 indicates an error, and errno is set to one of the following values:
E2BIG
Argument list (which is system-dependent) is too big.
ENOENT
Command interpreter cannot be found.
ENOEXEC
Command-interpreter file has invalid format and is not executable.
ENOMEM
Not enough memory is available to execute command; or available memory has been corrupted; or invalid block exists, indicating that process making call was not allocated properly. " >> MSDN reference
thats all !

What shell command? How are your using it?
>>but we're getting errors.
What errors? Runtime? Compile/Link? What?
