The [CLR Profiler](http://www.microsoft.com/en-us/download/details.aspx?id=16273) analyzes memory allocation. For performance analysis, I've found [SlimTune](http://code.google.com/p/slimtune/) to be useful. A quick Internet search should turn up a bunch of other tools as well.

I think you'll get the most value out of working with [parse trees](http://en.wikipedia.org/wiki/Parse_tree) of the expressions rather than trying to do it all with string manipulation. For reading in text equations, have a look at the [shunting-yard algorithm](http://en.wikipedia.org/wiki/Shunting-yard_algorithm).

I can get it to display just fine. Could you post your entire program?

[This seems most likely to be a problem with the DVD](http://answers.microsoft.com/en-us/windows/forum/windows_7-windows_install/installing-windows-7-error-0x80070570/44b72584-eab4-4dbb-a6ee-3874ec0d82b6)--maybe scratches or gunk on it.

> then I used GDB to debug testasm, and issued the command "disassemble main" Thus GDB gave you the disassembly for `main` and nothing else. Because you put `msg` in a different section, NASM could have put that anywhere in the resulting binary. If I recall correctly, GDB's `disassemble` command …

The [MySQL reference manual says](http://dev.mysql.com/doc/refman/5.1/en/create-table.html), "`KEY` is normally a synonym for `INDEX`."

You should be able to add an `xmlns` attribute to the root element of the XML document. What does the scanner return to you (*e.g.*, text, an XML DOM object)?

Which line is that exception coming from? My guess is it's one of your `Convert.ToDouble` lines.

Is the file hosted behind an HTTP server? An [HTTP HEAD request](http://en.wikipedia.org/wiki/Hypertext_Transfer_Protocol#Request_methods) should result in a 404 if it's missing, but if it's there, it won't send the body (*i.e.*, the file contents). [cURL](http://www.commandlinefu.com/commands/view/1685/send-an-http-head-request-wcurl) can do that.

Do you need help actually drawing the graph, or is your question about how to collect the data? Have you tried to write any code yourself yet?

Are both projects set up as 'Windows Forms' projects? One of them should be a 'Class Library' project, probably `form2`.

For the math part, read about the [shunting-yard algorithm](http://en.wikipedia.org/wiki/Shunting-yard_algorithm).

Here's your problem: int main(){ D* d; d->add(); You've declared `D* d`, but you never assign it a value. It could be pointing anywhere. Then you go and try to use this uninitialized pointer. That is an excellent way to get a segfault. I compiled this using GCC, and it …

What does "convert A to B" mean? The function signature `int BitSwapReqd(int A, int B)` tells us A and B are both `int`s, so it's not clear what we're converting here. Do you have a more explicit definition of the problem?

Negative numbers are integers; it's not an error to divide by them. Here's a sample run of your original code (compiled with MinGW): Enter any integer number -1234 -4-3-2-1 Do you get something different?

Have you tried to write any code yet? If you have, please post it and we can pick up where you left off. If not, that's fine too--I'm just trying to find a helpful starting point. Also, what's your major?

Compare `cout << employeeName << setw(20) << employeeTitle << setw(19) << employeeAge << setw(21) << employeeSalary << endl;` and `cout << "Employee Name" << setw(20) << "Employee Title" << setw(18) << "Age" << setw(20) << "Salary" << endl;` I see two things to fix: 1.

Try this: Instead of checking both the current node and the next node, just look at the current node. If the element you're considering is less than the current node, insert it before the current node. If it's greater or equal, move on to the next node. If you hit …

What's in `renderScene`?

Without code to look at, my best guess is that `main.h` doesn't have an include guard and is somehow getting included more than once.

[QUOTE=MR_88;1782169]Hi guys, I'm trying to use the random number generator as part of the GSL library and it is working fine for a few hundred 'rounds' of my code (it is used quite a few times per round) but then i get an error message in the command window: [CODE]gsl: …

Same thing has been happening to me in a variety of other forums too (everything I've visited in the Software Development area).

You might get more help posting in a language-specific forum. Regardless, `ing` doesn't mean anything in any C-derivative language I'm aware of.

[Framebuffer Object](http://www.opengl.org/wiki/Framebuffer_Object)&mdash;I believe you can load your image into a texture, attach it to a framebuffer object, then use it as the 'read' FBO and the front or back buffer as the 'write' FBO. I haven't tried this myself; perhaps someone with direct experience can validate the idea.

What kind of controls do these boxes contain? For a Mastermind game, I'd guess they're probably radio buttons, but it's better to be sure.

With finite storage, you can never detect all repeating decimals correctly. Say you completely fill up your fractional part array with the digits 1, 2, 0, 1, 2, 0, 1, 2, 0 (small array for example purposes). You might be tempted to say that it's 0.(120), but what if it's …

So... how much RAM do you have in your system? I recommend you keep an eye on the [URL="http://technet.microsoft.com/en-us/library/cc749154.aspx"]Performance Monitor[/URL] while your program is running. Watching the amount of free memory available might be very educational.

Depending on your OS, you probably have a simple "play this audio file" system call available. There are also a variety of third-party multimedia libraries that provide a more flexible audio API, for example, [URL="http://www.libsdl.org/"]SDL[/URL].
