Using variables wiht system()

Hello,
I was just wondering how i would use a variable with the system() function i get this error every time i try:
error C2664: 'system' : cannot convert parameter 1 from 'class String' to 'const char *'
No user-defined-conversion operator available that can perform this conversion, or the operator cannot be called

Thanks for your help Bender

you are tring to pass system a String, you need to use a const char*
does your String class have a function to return the string as a const char*? the stl string class has a function called c_str() which will do this.

Thanks for the response im preety sure my string library has a c_str() conversion function i found this in the my string library

Code:

---

const char * c_str( )            const;    // explicit conversion to char *

---

but i dont understand the syntax for it would it be somthing like

Code:

---

String Destination="c:\\windows";
Destination.c_str();
system(Destination);

---

your close, but the c_str() function returns a c-string, that c-string is what you want to pass to system() so...

Code:

---

system(Destination.c_str());

---

ahh thanks a lot:)
