    I already tried making mobName a string, but i got the same error, + the binary << error.... I tried using strcpy( mobName, currentMob.c_str( ) ); and got this error....

    C:\PROGRAM FILES\PROGRAMMING\MICROSOFT VISUAL STUDIO\MYPROJECTS\rpgfight\rpgfight.cpp(269) : error C2039: 'cstr' : is not a member of 'cMob'

    It all comes down to this error right here. Whenever I try to put any string in a variable (either using string x, or char x[]) and try to do cout << x; I get this error...

    Code:

rpgfight.cpp
C:\PROGRAM FILES\PROGRAMMING\MICROSOFT VISUAL STUDIO\MYPROJECTS\rpgfight\rpgfight.cpp(275) : error C2679: binary '<<' : no operator defined which takes a right-hand operand of type 'class std::basic_string<char,struct std::char_traits<char>,class st

    I am using VC++ 6.0, using namespace std; And I have the following include files....
    #include <iostream>
    #include <cstdlib>
    #include <iomanip>
    #include <cstring>
    #include <windows.h> //For Colors....

    Hi,

    It you list an error with your code, it's helpful if you show the code and indicate where the error is occurring with a comment in your code. It seems like an obvious thing to do.

    " error C2039: 'cstr' : is not a member of 'cMob'"

    That seems like a pretty obvious error message,

    strcpy( mobName, currentMob.c_str( ) );

    "c_str" and "cstr" are not the same.

    oh, I am sorry... I thought maybe it was a typo so I tried c_str and cstr.... I am thinking maybe it is my compiler, so I am downloading the SP5 pack right now... I saw someone post a similar message on another board when I searched on google, and in their situation the code worked with someone who has SP5 installed... If anyone has SP5 or another compiler and could compile this for me I would be very grateful!

    Code:
    void attack()
{
	         
	char b[40];
	strcpy (b, currentMob.itsName.c_str());
	system("CLS"); //Clear screen
	SetConsoleTextAttribute ( h, FOREGROUND_BLUE | FOREGROUND_GREEN | FOREGROUND_RED); //Sets the new text color

	cout << "Select a weapon to use:" << setw(40) << b << endl << setw(67) << currentMob.itsHP << endl << endl
		 << "F: Your Fists" << endl
		 << "B: Butter Knife" << endl
		 << "D: Dagger" << endl
		 << "S: Shortsword" << endl
		 << "L: Longblade" << endl
		 << "M: Mythril Longblade" << endl
		 << "B: Bow" << endl
		 << "C: Crossbow" << endl;
}
    compiles fine in VC++

    Actually the reason you were gettin the strcpy error is that what I meant was that you could use mobName as a string, and use the statement mobName = currentMob.itsName;, OR keep mobName as a char array and use strcpy.

    Guess I wasn't clear enough.

    Also, you forgot to include <string>. <cstring> is not the proper header file for std::string.
    Naturally I didn't feel inspired enough to read all the links for you, since I already slaved away for long hours under a blistering sun pressing the search button after typing four whole words! - Quzah

    "it's helpful if you show the code and indicate where the error is occurring with a comment in your code. It seems like an obvious thing to do."

    And when you posted your code, did you do that?
