Passing commands in CMD

[lumpybanana247]

So, I wanted to compile my java script in CMD via my C++ application.
I tried
system("cd C:\\ && javac HelloWorldApp.j ava");
and
system("cd C:\\ & javac HelloWorldApp.j ava");
which neither of them work

although, when i use cmd.exe and manually type
cd C:\\ && javac HelloWorldApp.j ava
everything works fine.
anybody have any suggestions?


EDIT
even when the file is in my directory C:\docs and settings\my username\
and i use this
system("javac HelloWorldApp.j ava");
..when opening cmd and typing javac HelloWorldApp.j ava works...
doesnt work

This may just be the wine talking, but have you considered 'escaping' them like you did the slash in the path?

ie

system("cd C:\\ \&\& javac HelloWorldApp.j ava");


?

thanks for your response. i have tried that and it had the same error... i edited my question right before you posted saying

I have another idea.
Put all the command in a .bat file and call the bat file from your code.
Check whether this works

And you tried escaping the '&'s specifically, as I posted above?

(As well as using the full path to the Java executable?)

thank you guys for your help.
it turns out for some reason, the current directory (cd) is ?Not set?... so i jsut typed

system("javac C:\\Docume~1\\U SERNAME\\FILE.j ava");


thank you

I'm guessing it is that the directory of the java executable is not in the path. If you added that folder to the path, you should be able to call it locally.
