How can I fetch it using onClick or something similar? e.g., [code=java] TableRow tr … |
| | Hey Tom, you can do this two ways. The easiest way would be to use a vector instead of an array: [code=c++]vector<Node> Tom(5, Tom(width)); //5 Tom objects calling Tom(width)[/code] The other way, if you want to (a) specify the parameters for each object or (b) continue using arrays: [code=c++]Node Tom[5] … |
| | I would also suggest sticking with arrays for now, especially since you have a set index. Something like this might get you going: [code=c++] int num = 0; string ary[25] = {"One", "Two", "Three", ... , "Twenty-Five"}; cout << "Give me a number: " << flush ; cin >> num; … |

| | Re: arrayas part2 I practically [URL="http://www.daniweb.com/forums/post1321810.html#post1321810"]gave you the answer[/URL] to this problem already (without the use of pointers and dynamic memory). Does your assignment require that you use pointers? |
| | Ok, so: #1 - What you're experiencing is due to something called early (static) binding. At run time, your compiled code has no clue about basePtr pointing to derivedObject. This is one reason you use virtual functions. If you noticed, your last function call did actually call the derived function … |
| | Your question doesn't make any sense! How are the values in the matrix generated? What are you trying to do?  |

 | Re: Function calls @embooglement: Unless the o/p has an application that requires this type of encapsulation or abstraction - in which case, simply calling from main() won't work. @o/p: I wouldn't avoid this type of design for the sake of preserving your [URL="http://en.wikipedia.org/wiki/Stack-based_memory_allocation"]stack[/URL], assuming it's because you're trying to maintain OOD.

| | Unless 6.0 is required, go [URL="http://www.microsoft.com/express/downloads/#2010-Visual-CPP"]here[/URL] and select Visual C++. That is the newest version of Visual Studio. |
| | You haven't corrected it. Take another look at firstPerson's post. You can implement your function just like you did the other three. [code=c++] bool checkGuess(int ans, int guess) { if ( ans != guess ) return false; else return true; }[/code] |
| | |
| | So the only thing you want is the last line of the file I assume... since your while() loop will not break until reaching the end of your file.  |
 | You could save the values to a file each time. Then use a function to read those values, and determine the Count you want to display.  |
| | Re: iterators Using the ++ operator on a pointer is different from a traditional variable. *ptr++ will increment the memory space which ptr is pointing to based on the variable type. For example, if you have [code=c++]int *ptr;[/code]and suppose it's pointing at memory location 1000. We know that an integer is 4 … |

| | Just use a break and loop like Fbody suggested. e.g., [code=c++] int answer = 1; while (answer >= 1 && <= 4) { switch (answer) { case 1: { cout << "what do you want to do?\n"; cin << answer; break; } case 2: { //do stuff cout << "what … |

| | How are you filling the data grid? Are you doing a SELECT * or some other query? |
| | VLSM can be very challenging for new networkers. What you're doing is essentially subnetting subnets. So for your example, if I understand it correctly, you have the following: HQ - 13 computers OUs - 39 computers/ea. So to start, you want to being with the subnet that will require the … |
