Hi again !

I have 2 more questions, and I know theyre simple for you guys, so I hope
you can help me.

1. Is there a c++ like command like system ? For example in c++ you can use
system("cd dir1"). I know this wouldnt go so well along with compability on
all platforms, but maybe there is such a command anyway ?

2. Is there any easy way to se if a string consists only of numbers (ex int)
? I can't find any method in string for this, or is there maybe some try,
catch I can use before using something like int i = Int32.Parse(myString);
?

TIA

System.Diagnostics.Process should do the job.

int a=0;

try
{
a = Convert.ToInt32(someString);
}
catch(InvalidCastException ex)
{
//something went wrong on parsing
}

Thanks, I always wanted to know how to do that.
