Use File.Copy(), it can recognize mapped drives as well as UNC paths.

> but I'm nub sooo, what is compiler flag? It's an option added to the command line invokation of the compiler. Right now you're probably only using something like this: $ g++ myprogram.cpp But you can add a huge number of options in the form of flags. For example, to …

I'm getting mixed signals here. What *are* you looking for? ;)

Do you have a more specific question? I'm not keen on writing an exception handling tutorial.

> You're effectively checking that a is equal to b and a is equal to c. You mean checking if a is equal to b is equal to c. Or in other words, if `a == b` and `c == 1` or `a != b` and `c == 0`. The …

> as you see isnt there a way like this or a function to do this ? The comparison operator doesn't work for arrays. Use a loop and write your own function: int compare_array(int a[5], int b[5]) { for (int i = 0; i < 5; ++i) { if (a[i] …

> why it doesn't hold for C++? I'd suspect that the person who wrote that was thinking of C++'s RTTI (runtime type information) features. That really has nothing to do with the sizeof operator though.

We use a third party library to linkify URLs, and it doesn't handle URLs with embedded parentheses. Handling parens is actually rather tricky because you have to consider parens that aren't part of a URL (like ([www.google.com](http://www.google.com))). We'd also need to integrate the change into Markdown and the editor highlighting …

> thank you so much I hope you're not expecting someone to just give you the code. Even if you provided sufficient requirements to write these functions, doing so is against Daniweb's rules because you've show no effort in doing the work yourself.

You don't need Office to access the provider, just the redistributable.

Arrays are an aggregate type, you can't simply use the assignment operator. Copying is performed with the strcpy() function. argv[1] is also a string, so \*argv[1] evaluates to a single character. I suspect you meant this: strcpy(target, argv[1]);

> my interst is C only. If you only care about C right now then I'd suggest reading the [standard](http://www.open-std.org/jtc1/sc22/wg14/www/docs/n1570.pdf) and attempting to implement parts of the standard library. On top of learning how to properly use the library by writing it, you'll also learn a lot about computer science …

Would it be in appropriate for me to ask if you could send the problematic image to me through email? That's easier than playing 20 questions until I can find one of my own that matches what you have and reproduces the issue. ;)

It places a value on the top of the stack. The equivalent would be: ; push [arg] sub esp, 4 mov esp, [arg] Conversely, pop will do the opposite: ; pop [arg] mov [arg], esp add esp, 4

The error isn't unclear or ambiguous. `width` doesn't have a predictable value when you try to use it. You probably wanted another input request to fill it in just like length: #include <iostream> #include <cmath> using namespace std; int main() { float length; float width; float area; cout << "Enter …

A good trick for avoiding this type of mistake is taking the size of the destination pointer rather than hardcoding the type: int **m = malloc(5 * sizeof *m); ... m[i] = malloc(5 * sizeof *m[i]); This works because sizeof doesn't actually perform the dereference, it just evaluates to the …

> If the question is unclear to you, please let me know. The point of this exercise is unclear to me. Is it just random homework from a teacher who thinks trivia will somehow make you a better programmer? Or do you have an actual real world need?

Can you post the implementation for Index2Pointer? That should be sufficient to write a test program.

This is wrong: char *string; printf("Enter a string of integers: "); scanf("%s", &string); There are four bugs here, and one of them is fatal. The fatal bug is that you're assuming an uninitialized pointer somehow points to infinite memory. Pointers *must* point to memory that your process owns, either by …

I'd say start by getting a simple barcode font, such as IDAutomation's [free 3 of 9 font](http://www.idautomation.com/fonts/free/) and creating some images.

You *can*, but my immediate question is why do you want to do so? There has to be a purpose for any level of indirection, otherwise it's just pointless complexity.

Do some research on virtual memory and paging. The answer is that active pages will use RAM while inactive pages will be moved to hard disk space until needed. Provided there's sufficient hard disk space to hold the inactive pages, the OS will behave as if there's infinite memory (at …

Introduction to Algorithms by Cormen, Leiserson, and Rivest is a good start. They use pseudocode for the implementation details.

Mask just the low byte after shifting and you'll get what you want: int red = (p >> 16) & 0xff; int green = (p >> 8) & 0xff; int blue = p & 0xff; Coincidentally, I did this very thing *today* while writing an image skew detection algorithm.
