• Multiple key map in c++

  - by Morgan

  Hi, I'm wondering if any of you know of a c++ associative map container type which I can perform multiple key lookups on. The map needs to have constant time lookups but I don't care if it's ordered or unordered. It just needs to be fast. For example, I want to store a bunch of std::vector objects in a map with an integer and a void* as the lookup keys. Both the int and the void* must match for my vector to be retrieved. Does anything like this exist already? Or am I going to have to roll my own. If so, any suggestions? I've been trying to store a boost::unordered_map inside another boost::unordered_map, but I have not had any success with this method yet. Maybe I will continue Pershing this method if there is no simpler way. Thanks!

• Mouse stops working after changing function

  - by heyohletsgo

  I'm making a console board game on c++, and i've been able to make the mouse work in the first function, the menu one, however, when i get to the getmove function and need to click on a house, it simply doesn't work.. Can anyone help? This is the class with the mouse. #include <cstdlib> #include <iostream> #include <process.h> #include <windows.h> #include <time.h> #include <stdio.h> using namespace std; void Game(); int Chu(); int rato(int &row, int &col) { HANDLE hIn; hIn = GetStdHandle(STD_INPUT_HANDLE); bool Continue = TRUE; INPUT_RECORD InRec; DWORD NumRead; HWND window = GetConsoleWindow(); POINT cursorPos; RECT wpos; int x = 0; int y = 0; //cout << hIn << endl; FlushConsoleInputBuffer(hIn); while (Continue) { ReadConsoleInput(hIn, &InRec, 1, &NumRead); switch (InRec.EventType) { case MOUSE_EVENT: if (GetAsyncKeyState(VK_LBUTTON)) { cout << "RATO"<<endl; GetWindowRect(window, &wpos); GetCursorPos(&cursorPos); cursorPos.x -= wpos.left; cursorPos.y -= wpos.top; x = (cursorPos.x - 5) / 16; y = (cursorPos.y - 25) / 24; cout << x << " " << y << endl; row = x; col = y; return row; } else if (GetAsyncKeyState(VK_RBUTTON)){ GetWindowRect(window, &wpos); GetCursorPos(&cursorPos); cursorPos.x -= wpos.left; cursorPos.y -= wpos.top; x = (cursorPos.x - 5) / 16; y = (cursorPos.y - 25) / 24; cout << x << " " << y << endl; row = x; col = y; return row; } break; } } } int main() { cout << "\n\n\n click on the stars" << endl; cout << " \n\n\n *******" << endl; int z = 0; int x = 0; int y = 0; int xo = 0; switch (rato(x,y)) { case 1: Game(); break; case 2: Game(); break; case 3: Game(); break; case 4: rato(x, y); break; case 5: rato(x, y); break; case 6: Game(); break; case 7: Game(); break; case 8: Game(); break; case 9: Game(); break; default: cout << "click again"; break; } return 0; } void Game() { int x = 0; int y = 0; int i = 0; cout << "GAME" << endl; do{ i++; rato(x, y); } while (i <= 2); Chu(); } int Chu() { int x = 0; int y = 0; int a = 0; int b = 0; int xo = 0; int yo = 0; cout << "\ click on the stars" << endl; HANDLE hConsole; hConsole = GetStdHandle(STD_OUTPUT_HANDLE); do{ xo = rato(x, y); if (0 <= xo && xo <= 5) { a = 1;} else cout << "CLICK AGAIN" << endl; } while (xo!=0); cout << a; return a; system("PAUSE"); }

• C# Array number sorting

  - by athgap

  Hi, I have an array of numbers jumbled up from 0-9. How do I sort them in ascending order? Array.Sort doesn't work for me. Is there another way to do it? Thanks in advance. EDIT: Array.Sort gives me this error. Argument 1: cannot convert from 'string' to 'System.Array' Right now it gives me this output: 0) VersionInfo.xml 2) luizafroes_singapore2951478702.xml 3) virua837890738.xml 4) darkwizar9102314425644.xml 5) snarterz_584609551.xml 6) alysiayeo594136055.xml 1) z-a-n-n2306499277.xml 7) zhangliyi_memories932668799030.xml 8) andy_tan911368887723.xml 9) config.xml k are the numbers from 0-9 string[] valnames = rk2.GetValueNames(); foreach (string k in valnames) { if (k == "MRUListEx") { continue; } Byte[] byteValue = (Byte[])rk2.GetValue(k); UnicodeEncoding unicode = new UnicodeEncoding(); string val = unicode.GetString(byteValue); Array.Sort(k); //Error here richTextBoxRecentDoc.AppendText("\n" + k + ") " + val + "\n"); }

• Intercept click event on a button, ask for confirmation, then proceed

  - by Blankman

  Based on a variable SomeCondition, I need to intercept a click event on a button, and ask for confirmation, if they say ok, proceed, otherwise ignore click. So something like: if(SomeCondition) { // disable click on button var isOk = window.confirm("Are you sure?"); if(isOk) { $("#button1").click(); } } Note: button1 has already been wired up with a click event via javascript from an external .js file that I can't change. I don't know what the click event was bound too, so I have to disable the click if SomeCondition is true, then ask for confirmation, then continue with the click.

• Proper thread termination in multi-threaded C# application

  - by Brian

  I have what I think is a rather complex problem. I have a C# application that utilizes a plug-in architecture using reflection. The application loads plug-in dlls and the user is able to enable/disable them. When a plug-in is enabled, the main app starts a thread to run the plug-in in. In many cases the plug-in may have multiple threads of its own. When I want to disable a plug-in I am calling Thread.Abort(). This seems to kill the initial thread that was created for the plug-in, but any additional threads that the plug-in created continue running. Is there a better way to stop all of the associated plug-in's threads along with the main thread? Thanks.

• Using content from the project in tests

  - by oillio

  I am working with Visual Studio 2010 and it's integrated testing functionality. I have an XML file in my project which is set to copy to the output directory. I can access the file just fine when I compile and run the project. But it doesn't exist when I attempt to access it within a TestMethod. It looks like the test is run with the working directory set to an "Out" directory created within the TestResults directory. I can set a breakpoint before I use the file. If I then copy the file into this "Out" directory and continue running the test it accesses the file properly. But that is not really how I want my automated tests to function. Is it possible to tell VS to copy the build directory into this working directory?

• Apache Modrewrite & 301 redirect- Dynamic URLs with characters.

  - by Ben Chesters

  I've been trying for weeks, literally, to rename these URLs and also ensure the old one is 301 redirected to the new one: www.example.com/?mod=11&p=215 - www.example.com/clean-url-section www.example.com/?mod=96&tab=6 - www.example.com/clean-url-section-2 Does anyone have any idea why I am having no luck, I got 500 server errors or nothing at all! Is it because of the question marks and characters? I'd be grateful for any help. I have tried this (below) and it seems to be redirecting to the http:// www.example.com/new-page (this page doesn't exist, as I only want it to rename the page BUT use a 301 so that search engines continue you to value it) RewriteCond %{query_string} mod=96&tab=6 RewriteRule (.*) http:// www. example.com/new-page? [R=301,L] Scratching my head!

• How to delay shutdown of an application when user logs off or shuts down Windows?

  - by badpanda

  I am writing an application that runs in the background from startup to shutdown, and in some circumstances I need the application to display a dialogue for the user to choose whether or not to continue shutting down. This application will only be running on Windows, but may be running on any version from 2000 onward. While I have certainly done some research on the topic, the information regarding the way that windows handles application shut down (http://msdn.microsoft.com/en-us/library/ms700677(VS.85).aspx) seems to be a bit scattered. If anyone has an example of the best way to handle this, or additional knowledge regarding the topic, I would very much appreciate it (I have very little experience with C#). Thanks!! badPanda

• Performing regex on a stream

  - by takoi

  I have some large text files which im going to preform consecutive matching on (just capturing, not replacing). Im thinking its not such a good idea to keep the whole file in memory, but rather use a Reader. What i know about the input is that if there's a match, its not going to span more than 5 lines. So my idea was to have some sort of buffer which just keeps these 5 lines, or so, do the first search, and continue. But it has to "know" where the regex match ended for this to work. e.g if the match ends at line 2 it should start the next search from here. Is it possible to do something like this in an efficient way?

• Codeigniter pre_system hook for DB driven dynamic controller selection - best approach?

  - by Andy

  Although I can tentatively see a solution to this, I was wondering if there may be a glaringly obvious simpler approach. My aim is to use the first segment of a given URI to query the DB as to which controller should be run. I assume I would have to reform the URI with the resultant controller name in segment 1, then allow the system to continue processing as normal (hence a pre_system hook). Although not essential I would also like to hold a couple of other variables from the same DB request to be used later in the call stack, and assume this would have to be done using global variables? Any better suggestions would be gladly received. Thanks.

• How to Design Programs: An Introduction to Programming and Computing -- teacher guide access

  - by user295683

  Hello -- I'm a biologist switching careers, and trying to learn programming as a result. I stumbled upon the aforementioned book on Amazon, which jived with my liberal arts background. Despite my great satisfaction with the didactic approach, I was frustrated to see that the answers to the exercises are restricted to teachers only. As I am pursuing this endeavor on my own, this restriction dramatically cripples the value of this book. My request to the author's website for access to the answers has not been answered, and I would desperately like to continue with this book. Anyone have any experience dealing with the book's website, or at the very least a torrent of the answers? Otherwise, I suspect I will be relegated to using JavaScript for everything! Thanks!

• Microsoft Visual Studio License

  - by Germstorm

  I developed a small winforms application for myself in Microsoft Visual Studio 2008 Professional Edition at my workplace, the Visual Studio is licensed to the firm I work at. If I want to sell that application, what are my license options? EDIT: The issue here is not my relationship with my employer (the code was written after hours, we have an understanding) but my relationship with Microsoft. Ex. if I continue developing in Visual Studio Express can I keep my old code? Is there a way to verify if some assemblies were written using a Visual Studio Professional?

• SEO: It's recommended to upload and put live a beta / non-finished version of web site??

  - by Jonathan

  I'm working on this big website and I want to put it online before its fully finished... I'm working locally and the database is getting really big so I wanted to upload the website and continue to work on it in the server, but allowing people to enter, so I can test. The question is if this is good for SEO, I mean, there are a lot of things SEO related that are incomplete.. For example: there are no friendly URLs, no sitemap, no .htacces file, lot of 'in-construction' sections... Does Google will penalize me forever? How does it works? Google indexes adn get the structure of the site just once or its constantly updating and checking for changes??? What i should do? What you recommend?!!?

• Create "duplicate copy" of github repository

  - by user1483934

  I see answers to similar questions and I'm sure I may just not be familiar enough with Git and Github terminology to know if they apply to my question. What I need to do is to clone an existing Github remote repository (a private repo under another person's username that I have contributor access to) and create a new private remote repo under my account. The existing repo user is going to make significant alterations to the repo, delete, and re-push, before they do that they want me to clone and create a duplicate so we can continue working from the repo under my user. I want to preserve the commit history with the repo if possible. I've cloned locally but don't can't seem to figure out how to push it to a new remote that isn't origined to the original user.

• What are some ways to identify a logged in user on the web?

  - by farinspace

  Here is the scenario: There are 5 websites (different domain names) that need to share a session. I am using a bit of code on each site which returns a "blank.gif" image and at the same time sets the session (syncing it up to the current session). Each of the sites calls a session-img from each of the other sites. Also, all sites have access to the same database (where the session is stored). This works great on FF and Chrome, but not on IE (or Safari PC)... I need to come up with an alternative method to keep a session active? The app is a small custom CMS, so really only 2-3 people will be using it. I can probably identify user logins by IP and then continue to check for the IP accross all sites... Is there something more granular such as a computer uuid that i can check for?

• WPF Dragging a window to the desktop

  - by pfaz

  I've seen some nice Adobe AIR demos where a component of the application is dragged outside of the application and dropped onto the desktop and then continues to run in a new window. This seems to be facilitated by the NativeDragManager class. Is there anything similar in WPF? How would you go about implementing this sort of functionality in WPF to allow a user control to be dragged to the desktop and then continue to run in a new window? This is great for multi-monitor scenarios and exactly what msft have added to vs2010. Regards pfaz

• Function chaining depending on boolean result

  - by Markive

  This is just an efficiency question really.. I'm interested to know if there is a more efficient or logical way that people use to handle this sort of scenario. In my asp.net application I am running a script to generate a new project my code at the top level looks like this: Dim ok As Boolean = True ok = createFolderStructure() If ok Then ok = createMDB() If ok Then ok = createProjectConfig() If ok Then ok = updateCompanyConfig() I create a boolean and each function returns a boolean result, the next function in this chain will only run if the previous one was successful. I do this because an asp.net application will continue to run through the page life cycle unless there is an unhandled exception and I don't want my whole application to be screwed up if something in the chain goes wrong (there is a lot of copying and deleting of files etc.. in this example). I was just wondering how other people handle this scenario? the vb.net single line if statement is quite succinct but I'm wondering if there is a better way?

• How to load the content of a page into another window?

  - by Cristian Castiblanco

  I'm building a Dashboard and for some stupid reasons my boss wants to load it in a frame on the homepage (yes a frame, he still lives in the 1990s). Anyway, sometimes the dashboard needs some room so that it can show all charts correctly, so I want to add a feature to load the content of the dashboard into a new window. The problem is that, if the user has had some interaction with the dashboard, it will contain modal dialogs, new images, etc... so I want to load all the dashboard content into a new window without reloading its content. Of course, the user should be able to continue browsing the dashboard without problems. How can I do that? I'm using jQuery as my JavaScript framework.

• store data in asp.net pages (Not Sessions)

  - by ARB

  I am creating 4 asp.net pages. first three pages have 'CONTINUE' button and last page has 'SUBMIT' button. I am not allowed to use Sessions to store first three pages data. and i need to use 'BACK' button on last three pages. when i click 'BACK' button i need to maintain the previous page data entered by user. As my pages do some postbacks, i cannot use javascript.history function. My restrictions are: As the application is served from a web farm, a session object cannot be used. However, for the purpose of this excersise, consider session object as database-like persistent space where you can store your data. your code should show an easy way to switch to a different persistent space. What is databse like persistent space and how to write a code to switch to different persistent space?... Please give me some idea on how to proceed.... Thank you

• Simple iPhone tally method question

  - by Rob

  Just trying to create a simple method that counts up 1 on the tally when the button is pressed. My knowledge is extremely limited and I am pretty sure that my problem is somewhere in the method implementation: -(IBAction) updateTally:(id) sender { NSString *text; int total = 0; total = total + 1; text=[[NSString alloc] initWithFormat: @"%i", total]; lblTally.text = text; } I have done the necessary interface declarations for the lblTally UILabel and the updateTally method. I suspect that there is some sort of an NSString/int/%i/%@ mixup that I am making but I'm not sure how to fix it. When I run the program as it currently is it displays a 0 in the lblTally label field on the iphone. When I press the button it then displays a 1 in that field. However, if I continue to press the button - nothing happens.

• Bash init.d script detect that mysqld has started and is running

  - by Ricket

  I'm working on my dedicated server running CentOS. I found out that one of my applications which starts up via a script in /etc/init.d/ requires MySQL to be running, or else it throws an error, so essentially I currently have to start it by hand. How can I detect, in a bash script (#!/bin/sh), whether the MySQL service has started yet? Is there some way to poll port 3306 until it is open to accept connections, and only then continue with the script? Or maybe set an order so that the script doesn't run until the mysqld script runs?

• 'Best' way to pull data relative to a div?

  - by acidzombie24

  This answer suggested i should put my data in JS instead of a textarea. Thinking about it i could have scripts and do something like myarray[i]="data" where i is the index of my for loop. However when i click a div how do i find out what i is? I have used var data = $(this).parent('.parent').find('.valuestr').eq(0).val(); which is extremely simple. Should i use a script or should i continue to do it with a textarea? if i should use a script 1) Whats the easiest way to find i and 2) Is it bad pratice to have dozens or hundreds of <script> in my html? or i can go through the loop twice but i still dont know the easiest way to find i. I would have to store it somewhere or go through multiple tags and count them.
