Hello,
Im trying to invoke a simple perl script with in my visual c++ gui
program to with c++'s system call feature:
when i call:
system("dir");
it works
when i call:
system("c:\perl\bin\perl.exe c:\temp\perl.pl");
it does not work
when i cut and paste
c:\perl\bin\perl.exe c:\temp\perl.pl
into the command line, it works.
Does anyone know why?
Thanks,
AG

Ok, here's how to make it work.
Use
system("c:\\perl\\bin\\perl.exe c:\\temp\\perl.pl");
instead.
In C++ the compiler sees "\" as the start of an escape command. For example \n starts a new line.
Type "\\" when you want to use the actual \ character.
