Problems using System();

[Ertzel]

I am trying to use the Net User command from the cmd in my C++ program. I have this...

char acUserName[100];
DWORD nUserName = sizeof(acUserName);

if (GetUserName(acUserName, &nUserName)){
cout << "User Name: " << acUserName << endl;
   system("Net User");
}

This displays the User Name on the screen and then also calls the Net User function, This part works fine. What I'm having problems with is I want to use the Net User username function with the acUserName the program already gets.

The only way I can think of doing that is....

char acUserName[100];
DWORD nUserName = sizeof(acUserName);

if (GetUserName(acUserName, &nUserName)){
cout << "User Name: " << acUserName << endl;
   system("Net User " && acUserName);
}

But I get the following error "cannot convert `bool' to `const char*' for argument `1' to `int system(const char*)' "

I can't figure out how to make this work. Can anyone help me out with this please?

so you want the system call to say "Net User name"? If that's all then you can use a string and put the two parts together and then pass the whole thing to system.

string command = "Net User ";
string name;
cout << "please enter the user name: ";
cin >> name;
commmand += name;
system(command.c_str());

Ohhh I forgot about the .c_str() command. I still need it to work with the user name already found but that works using .c_str().

My code looks like this now

if (GetUserName(acUserName, &nUserName)){
   string command = "Net User ";
command += acUserName;
   system(command.c_str());
}

and everything works as needed. Thank you for your help.
