| | 1) 2) and 3). Very little, if any, performance gain. Those are not areas to optimize because the compiler will do that. 4) You talking about c++ classes? vertual class methods are extremly handy and I've used them often at my work (before I retired that is). >>the virtual functions …  |
| | system boot time is the value returned by GetTickCount(). If you want to know the actual date/time, call time() function in time.h, then localtime() to get struct tm pointer. From that subtract the number of seconds returned by GetTickCount(), pass that result to mktime() (from time.h) which will do all … |

| | you can use either sprintf() or strcat() to format the output file name. Example: [code] char outname[255]; char inputname[255]; char* ptr; printf("Enter a file name\n"); fgets(inputname,sizeof(inputname),stdin); strcpy(outname, inputname); // truncate the extension ptr = strchr(outname,'.'); if(ptr != NULL) *ptr = '\0'; // now add new filename strcat(outname,"_res.txt"); [/code] |

 | You can add controls, but it might be easier to use CFormView which is derived from CView but acts like CDialog. To add a button to your CView, just create an instance of CButton in the CView's class, then when initializing CView class call the button's Create() method. Of course … |

 | One solution: replace [icode] int store[10];[/icode] with either std::vector or std::valarray. With these you can store seemingly infinite amuont of numbers (of course it isn't really infinite, but close enough for most practical purposes). |
| | Re: File management Yes, we can help, but not without knowing the details of the text file. Exactly what is in the file and how is it formatted. Post an example of the file. Once you know that, all you have to do it open the file with ifstream object then read sequentially … |
| | Re: Packet Filter >>Can someone help me on maybe how to start ? Depends. Are you comfortable with writing c++ programs? If no, then start by learning the language. If you know how to write c++ programs, then what is your knowledge of socket program? None, then google for socket program tutorials. |
| | Start by understanding the mathametics of the triangle -- see [URL="http://en.wikipedia.org/wiki/Pythagorean_triple"]this wiki article[/URL]. That article gives you the solution for the 16 primitive Pythagorean triples with c ≤ 100. That should give you the data you need to verify the accuracy of your program. One way to do it would … |

| | It just means you can use C language to build gui MS-Windows programs. You can also use other languages, such as C#, VB, php, C++, and others. The win32 api functions were made by Microsoft to be called by as many different programming languages as possible. windows.h is just a …  |

| | Depends on what you mean by "call my program". If you just want to launch the already compiled *.exe program then the answer is Yes. There are several ways to spawn an executable program. system() is one such function, win32 api CreateProcess() is another. Why do you want to use … |
| | Its defining a pointer to a specific address. Works ok (probably) in MS-DOS version 6.X and earlier where that type of syntax was sometimes used, but it will fail in any modern 32-bit operating system such as MS-Windows and *nix. So if you are using a modern compiler then those … |
