 | If the documentation for Open AL is too confusing for you, how in the world do you expect to ever use it? |
| | Your program is a confusing mixture between C and C++. It contains duplicate #include statements and you are using both cout and printf(). It looks like you took someone's C program and attempting to make it your own c++ by just adding cout and leaving all the rest of the …  |

| | First learn how to properly format your programs. I helped you out this time by doing it for you just so you can see how it should be done. There is absolutely nothing wrong with being generous with spaces and line feeds -- makes your program a lot easier to …  |

| | I don't know what GetHeath() returns, but you can't use it when reading the data file. What does that function return? And what are the parameters to SetHeath() ? In the read function you will need to do something like this: [code] char something[255]; continueData >> playerName >> [color=red]something[/color] >> … |
 | A DLL is a library of functions that are shared among other executable programs. Just look in your windows/system32 directory and you will find dozens of them. When your program creates a DLL it also normally creates a lib file so that the application *.exe program can resolve symbols that … |

| | IMO you should not try to integrate the gui into that old DOS code, but rather to write a whole new GUI that includes the features of the old code. First create the gui windows and dialog boxes the way you want them. After you finish that you will probably …  |

| | >>return &c; That is returning a pointer to an object that was created on the stack. Your compiler correctly flagged it as a warning, but its is really an error. It is an error because variable [c]c[/b] is destroyed as soon as the function f() returns, and consequently the line …  |
| | First, you created the wrong kind of project. You created a win32 console application instead of an empty CLR project. After creating a new empty CLR project copy the *.cpp and *.h files into the project directory then add them to the IDE. After that the compiler will not give … |
| | Yes you can use it, but I won't suggest it. Its a whole lot easier to use fread() and fwrite() to read/write to/from binary files. [code] // fgetc example float f = 0; unsigned char buf[sizeof(float)]; FILE* fp = fopen("myfile.dat", "rb"); // read a float for(i = 0; i < … |
| | Re: 2D Array So you want to find the smallest number in an array. First, create an int that will contain the smallest value and set its initial value to the first array element. Then loop through the remaining array elelments, test if the element is smaller than the counter. If it is … |
