 | Re: Cocktail Quiz hmm, I got 6 out of 10... Score said 5-6 > Not too shabby.. So I guess what I've heard people saying about me is true...I am a bit of a bar-steward! At least, that's what I think they've been saying! ;) heh heh! I couldn't take the other test...The …  |
| | It took a bit of playing around, but think I've found a workaround for this.... I noticed in the docs for os.system() (Yes I RTFM!) it mentions that the subprocess.call() should be used instead. So I had a go with subprocess.call() but I soon ran into very similar problems, it … |

| | What about replacing the backslashes with forward slashes? So wherever there was a single backslash, replace it with a forward slash. That should also fix your problem! I know typically in Windows, filepaths look like this: C:\SomeDirectory\SomeFile.ext But in C++ forward slashes are also acceptable for file paths.. c:/SomeDirectory/SomeFile.ext The … |
| | OK, I started working on this when I saw your original post. But since I started, you made your second post. So I've modified it a little to give the line numbers; but I've not got it to output the character position yet! I've done the search using the re … |

Thanks.[/QUOTE] As far as I understand it, they are both valid and correct. When passing an array … |
 | Hey all, This isn't so much a question as a heads up... After using python for a few years (mainly doing blender scripts and random console/command-line apps and tools) I've recently started looking into doing some GUI based stuff using wxPython. I've had a look at a few of the … |
| | Hmm, your after fixing your originally posted code (which you've already done)... When running the code I got an index out of bounds error.. So I've made a minor alteration..Not sure if you've already found and fixed this but... [CODE=PYTHON] import math def polyPerimeter(xyList): perim = float(0) count = len(xyList)-1 …  |
| | [QUOTE=The-IT;996893]hi, I just created this awesome python application and i want to spread it around, but every one has python. I was just wondering if I could compile python source into a linux executable like py2exe, and then compile the executable into a .deb installer file. any help would be … |
| | Firstly 'input' is a reserved word in python, it's used to get input from the user, (rather like raw_input!). So that's why this line of code fails to do anything: [CODE=PYTHON] input = raw_input("Type Date dd/mm/year: ") [/CODE] Change your variable 'input' to something like 'userInput' or just anything that … |
| | OK, well...I'm not familiar with this code, so I don't know exactly where it's from but: [CODE]DECLARE_STDCALL_P(struct hostent *) gethostbyname(const char*); [/CODE] breaking it down into three parts: DECLARE_STDCALL_P is some kind of macro...Offhand I'm not sure exactly what it does...probably registers the function with some system mechanism or other.. … |
| | The description of your problem is at best vague and at worst confusing...Being able to see the code that's actually causing you the problem would help! So if you could post some code it would help us to help you! (Just don't forget the code tags!) Also, regarding your question … |
| | OK, here's a very simple class and some code to test it, based on what you posted previously! [CODE=PYTHON] # here's a simple class class MyClass: # class constructor/initialisation # if no string is passed, defaults to an empty string def __init__(self, aString=""): self.myString = aString # addText function def … |
| | OK, well there are a few problems with your error checking/input validation. Also your loops are a bit wierd, the program continues after it guesses correctly. And the number guessing algorithm looks a bit dodgy too! Here's a slightly improved version of your program. Changes made: I've used a very … |
| | Considering the problem you have set, your algorithm is completely wrong. And as already mentioned by niek_e, you're using the for loop incorrectly too! Follow niek_e's advice and take a good look at using for loops. His post shows you how to correctly use them.. And as he's already said, … |

| | Ok. As you're using a std::string to store your URL and ShellExecute is expecting a pointer to a C style string (LPCSTR) as a parameter, you simply need to change your ShellExecute call to: [CODE=C++] ShellExecute(NULL,"open",URL.c_str(),NULL,NULL,SW_SHOWDEFAULT) [/CODE] The c_str() function of the standard library std::string class returns the contents of … |
 | Personally, I wouldn't miss either of 'em! The only reason I own a mobile phone is because my wife and my bandmates nagged me into it, so they can pester me incessantly....So if my phone should ever so accidentally on purpose fly off my desk and into the wall...ooops!.....Hey if …  |
| | Re: Image flickering Hey Raja, I don't know if you've already solved this but I'd pretty much agree with Iamthwee! Upping the frame rate of your final movie should minimise jerkiness a little. And it is true, the default flash tweens can be a little buggy at times...Also Tween lite is a very … |
| | If all you want to do is remove the floating point digits you could do this: [CODE=PYTHON] floatValue=3.141 integerValue = int(floatValue) print "The integer equivalent of", floatValue, "is", integerValue [/CODE] Note: The above code is python 2.x syntax. For python 3.x change the print statement to: [CODE=PYTHON] print("The integer equivalent … |
| | I could be wrong, but I don't think that theres a way of getting your max_iter iterator to give away the position of max_element...Unless Torture works heh heh...Bring on the COMFY CHAIR! :D (Apologies for the Monty Python...I couldn't resist!) Anyway, this is about the only thing I could come … |
| | Re: Error C3861 In main() you aren't instantiating your matrix class correctly. Also your add and multiply functions are currently member functions so you'd have to access them via an instance of your Matrix class. To correctly instantiate your class you need to do something like: [CODE=C++] Matrix* mat1 = new Matrix(rows, cols, …  |
| | You can't hide the background. When you published your .swf it sounds like you published it with a white background. Unfortunately .swfs don't support having a transparent background, so you have to set the background colour you want. You can either do this at publish time or dynamically at runtime. … |
| | Ah yes, I should've spotted that howler when I helped you yesterday! For the last people you ask, their votes are not getting counted.. What you need to do is ask for input before the switch, so perhaps try something like this: [CODE=C++] #include <iostream> using namespace std; int main() …  |
| | Your indentation goes a bit off from line 26 onwards (but that is more of an aesthetic thing which affects the readability of your code, it doesn't affect the code in any other way..The compiler doesn't care about whitespace or readability of code..As long as the syntax is correct the …  |
| | I'm not sure exactly what kind of tweaks you're thinking your users might be likely to make to your script, but if your users aren't likely to be needing to make any structural/logical changes to the script. Or in other words, if they're only likely to be changing the values … |
| | Re: Enquiries C++ [QUOTE=D.JOHN;950788]I have this question, Is it possible to use int student,subject; student=5; subject=3; int marks[student][subject] instead of const int student(5),subject(3); int marks[student][subject]; ?

| | This concept seems really strange to me... You've created a class called Mp3 and a class derived from Mp3 called Frame, but the Mp3 class has members which are instances of Frames??? I could be wrong, but I don't think it's possible to do that in C++. In all my … |
 | OK, well the error messages say it all... For starters you need to uncomment the definition of RAND_MAX which is the cause of your error. Secondly, as Salem has pointed out, you need to include stdlib.h, which will get rid of the warnings about rand and srand. Finally line 116: … |
| | I remember having similar problems using flash 8 several years ago.. Certain extended ascii characters wouldn't show up in dynamically loaded text. The solution was to select the dynamic textbox that the text was loaded into, open the properties panel and click on the 'Embed..' button. This allows you to … |
| | OK, this should take about 30 seconds to fix..... 1. Open up your fla. 2. Take a look at the two layers called 'acciones' at around frames 100-120. In the top 'acciones' layer at frame 103 there's a keyframe with the framelabel 'intro'. Now take a look at frame 117 … |

| | I'm not sure which compiler you're using, but usually you'd register any 3rd party libraries with your compiler. e.g. In Visual Studio 2003 you'd: In the Solution Explorer, right click on your project and select 'properties'. In the property pages, select the 'C/C++->General' item in the tree. Now select the … |

| | Alternatively, if the musicback1 script is complete and working, what you could do (especially if musicback1 is used elsewhere in your app) is define another function which calls musicback1 and then does any other bits that you want. Here's a little pseudo-code to demonstrate what I mean: [CODE=PYTHON] def musicback1(): … |
| | [QUOTE=NeoFryBoy;943182]Quick background: I'm working on Project Euler and made a palindrome checker.

[I]I have fixed it, but could somebody explain … |
| | In standard C++, to make a function overridable, you'd make it virtual in your base class. So perhaps you need to change the signature of your isKnownWord function to: [CODE=C++] public: virtual bool isKnownWord(){}; [/CODE] Then in any derived classes you can override the function, all you'd do is declare … |

| | Re: Issue Tracking What about Bugzilla? I believe it's open source, it's certainly free and it can be used with various CVS systems SVN/GIT/VSS/Perforce etc... Every company I've worked for has used it for tracking bugs, my previous employer used it with SVN(nice!) and VSS(blech!). My current employers use it with Perforce(nice!). From … |
| | OK, After this line: [code=PYTHON] label = Tkinter.Label(pg4_group.interior(), image=photo) [/code] try adding the following: [code=PYTHON] label.photo = photo [/code] This will create an instance of your image in the label, preventing it from being garbage collected (Which is what I suspect is going on!). Next, after your call to label.place, … |
| | Well, I'm not familiar with the component you're on about, but generally the source folder and it's subfolders will contain the source files you'd need if you decided that you wanted to modify/customise the component. You don't need to put any of these files onto your server. The stuff in … |
