C / C++ / MFC

Thank you all of you. Yes, that was the problem, I should put arrByte2.SetSize(sSerial.GetLength() + 1);

No, it's a one-dimensional array of pointers.

Thanks

THANKS SO MUCH ;)

I would be tempted to use strtok(). Then just read the returned value in reverse order.

Do what Richard says encrypt it when your write and decrypt when you read it. You can go from simple XOR encryption if it isn't that important to the real heavy stuff and there is a pile of libraries and code out there. In vino veritas

Have you made sure you open the file for write in binary mode. FILE * binfile = fopen("somefilename.bin", "wb"); //Open writable bin file You open it with just "w" command and it's in text mode some of the raw struct characters will be translated to tabs, CR, LF etc. In vino veritas

i will do it as many times as needed until i get the concepts.

I showed you where to find the answer two days ago: read the documentation.

it works too.. #include #include #include int main() { int log, i, j, k, count1=1, count2=0, c; printf("Enter the number of logs: \\n"); scanf("%d%\*c", &log); char names\[log\]\[100\]; //Entering names. printf("Enter names: \\n"); gets(names\[0\]); //completing in a single loop. for(i=1; icount2) { puts(names\[0\]); printf("Wins !"); } else if(count2>count1) { puts(names\[k\]); printf("Wins !"); } else if(count1==count2) { printf("It's a tie!!"); } break; } count1++; } return 0; }

Yes, I have: void CMainFrame::ActivateFrame(int nCmdShow) { // TODO: Add your specialized code here and/or call the base class TRACE(_T("======================================================AAAA\n")); CMDIFrameWnd::ActivateFrame(nCmdShow); } and there is no trace in output window ...

It seems to be, and we are seeing more and more of this type of question here. I guess they have all bought into the idea that you can make a lot of money as a developer with minimal training. Just pray they are not working at your bank or local hospital.

I would advise you to try some experiments. It can be very simple. Write a simple class hierarchy with derived classes and have them call a virtual method each of them implements. Within the method, have it output a trace statement (TRACE, printf, cout<<, what ever...) You will see the calling sequence by the order of the output. One thing to be careful of is the order of the calls : virtual void TestMethod( int n ) { __super::TestMethod( n+1 ); // call base class trace( _T( "in TestMethod( %d )\n" ), n ); } // versus : (base class first or base class second) virtual void TestMethod( int n ) { trace( _T( "in TestMethod( %d )\n" ), n ); __super::TestMethod( n+1 ); // call base class } The output will show you which comes first. Implement as many derivation levels as you want, at least three I think. The base class won't have a __super so you will have to comment that off for it. Anyway, I recommend that you try this experiment. It doesn't take long and it is very informative.

You can always count backwards from the end, find the first / and insert the value before that. String parsing like this, C style, is done a heck of a lot. It is light weight and very quick.

You are using multi dimensional vectors and loops. That are costly operation. Set you loop params (like 500) to a small number to see the difference. :rolleyes: Press F1 for help or google it. Greetings from Germany

I got tired of looking.
