| | Re: C++ Socket bug > int dataLen = recv(client, recvBuffer, 1024, 0); You're assuming several things (all of which are false, eventually) 1. That for every "message" sent, you get "message". STREAM sockets can fragment the message (only the byte order is guaranteed). So you might get "mess" or even "messagemessageme". 2. That every … |
| | [url]http://www.daniweb.com/forums/announcement125-2.html[/url] Here's some questions for you - how are the switches and display wired to the processor? - how are specific elements of the display selected? Perhaps begin with something simple, say incrementing a digit every time a key is pressed. It's not much, but you'll learn a lot, and … |
| | Well if you showed us how you declared and initialised your array, then we could tell you how to pass it to a function. Hint: just copy/paste the original declaration into your function prototype. |
| | Start with trivial input files, like say 1 2 A B then try 2 3 A B B C Trying to debug with large data files just clouds the issues. Another thing to add (for your own benefit) is a 'dump' function you can call to just print the entire … |
| | So why can't you recursively evaluate A -> B -> C ? a1 = eval( eval(a2) + eval(a3) ); When you get to a3, you see that you need to do another eval() Is this a plan? The only problem you need to watch out for is if there is … |
| | > while(nextPermutation(elements,n)); But you marked the function as returning void. You need to return a value indicating if there are more permutations. |

| | No, you're wrong. argc is a COUNT of the number of arguments, it has nothing to do with the value of any single argument. All the args are in argv[] as a series of string, which you need to covert. So a long long int would be a string in … |

Try. - printing hello from a string already initialised in your program - printing a string as the user types is (letter for letter) - printing a whole string as entered by the user … |
| | Can you post an example in context? A single line "what's this do" means nothing. |
| | Re: Pixel alignment So run it in the debugger, and find the line of code which actually triggers the memory fault. Don't just post a few lines of code for your "best guess" and ask "what does this look like?" |

| | > Why does this happen? Because TCP is a stream protocol. All it guarantees is the order of the information. Breaking that into packets is your problem. You might send "hello world\n" "bye world\n" in two separate send calls but on any given test, you might get "hello world\nbye" " … |
| | Because passing an array to a function reduces it to just a pointer to the first element, and the size information is lost. Just like it were a regular function. |

| | > int f = atoi(&from); Simply creating values of the right type isn't enough. You need to know what's going to happen next. atoi() expects an ARRAY of characters ending in a \0 character. This, you do not have. You have a single char and undefined values following it (so … |

Sure, if you want to do the heavy maths, and bash out all the pixels yourself before rendering it. Perhaps there are better controls? |
| | Maybe ask them the question? My eyes are bleeding from straining to read yellow text on a green background - puke puke puke. My guess is one or more sample values jump to one of the sample limits (and pretty much stays there). |

| | Meh. +1 for managing to use code tags on the first post - that was promising... -1 for posting code lacking any indentation at all. -20 for just dumping a sorry mess of code and not saying a damn word about it. What's wrong with it? What does it do? … |

| | Most of the IDEs I know save the compilation/interpretation to external tools. So a simple wrapper around - edit file using an editor - pass file to compiler - gather error messages. All of this is mundane stuff compared to writing a compiler. Maybe grab the source code for code::blocks …  |

| | Unless your union has members which are all the same size, you're stuck. When you assign values to your array via the union (for the shorter types), you get a lot of holes in memory which are not filled in. However, when you try to recast that as a pointer … |
| | > As for the behavior...Try it and see what happens. Bad idea - they might think it works. @OP if you didn't call malloc(), then DON'T call free(). if you did call malloc(), then call free() exactly once. |

But you also need to say which library you want, with the -l option (that's lower case L). If the library is lib[COLOR="Red"]lua[/COLOR].a for example, you would add -l[COLOR="Red"]lua[/COLOR] to the command line. |
