Hello all, I would like to know if and how it is possible to launch a DOS program from my SDI program running in Windows 2000. The program is called allowio.exe and in DOS prompt the command to run it properly is:
allowio test.bat /a
Any thoughts on what command to use and how to include the parameters ("test.bat /a")?
There are a variety of methods available.
You could simply make a system call:
system("allowio test.bat /a");
...although this method is probably not PC these days.
There's the spawn functions, with a likely candidate for your needs being:
_spawnlp( _P_WAIT, "allowio", "allowio", "test.bat", "/a", NULL );
There are others too, _exec, ShellExecute. I'm sure there are more...
Hope this helps,

What if you have a dos program and you want to launch a Windows program.
Is there a switch the you can set on the compiler to lauch the program from command.com????
Take a look at the following FAQ... :cool:Quote:

Okay, it works with:
_spawnlp( _P_WAIT, "allowio", "allowio", "test.bat", "/a", NULL );
but I have the problem it blocks my application till I close the launched DOS application down, while both are supposed to run simultaneously. Anyone knows how to launch a DOS program as a seperate thread?
How about calling it asynchronously!! Pass the first parameter as _P_NOWAIT or _P_NOWAITO, and check MSDN for description!!
Nevermind my stupidity, I found it out already. _P_NOWAIT indeed. MSDN doesn't really describe _P_NOWAIT with _spawnlp by the way.
yeah, sorry about that. The MSDN indeed is missing the descriptions.
