System function (C++) - Dignity - 12-17-2011
Here's what I'm trying to do
Allow users to type in a website (eg google.com) and then use the system function to launch net.exe
I have figured out how to launch net but not how to type cast the string
Google has failed me here
RE: System function (C++) - noob007 - 12-17-2011
It's simple if you're using std:
tring:Code:
std::string exe = "net.exe ";
std::string webpage = "google.com";
system(exe + webpage);RE: System function (C++) - Dignity - 12-18-2011

Expect I'm getting user input, where I have to cast it.
But, let me try your idea first.

If you're getting user input, you might as well use this:
Code:
std::string exe = "net.exe";
system(exe + USER_INPUT_STRING);RE: System function (C++) - Dignity - 12-18-2011

Cannot convert `std::basic_string<char,

C++ strings are different from C strings, which leads to a lot of confusing bugs like that... It's why I switched to Java. Good luck.

You switched to Java just because of the strings? Really? How often do you use strings, anyway?
Anyways, to Roperson, try this:
Code:
std::string exe = "net.exe ";
exe += USER_INPUT;
system(exe.c_str());Sorry about my previous post.

You did it.
