• Custom GMapTypeControl buttons (Google Maps V2 API)

  - by AndiDog

  A similar question was already asked, but does not have a satisfying answer. I want to change the CSS style for the map type selection buttons (which are actually DIVs that don't have a CSS class). The links in the referenced question show how to subclass controls, but the examples don't seem to work for GMapTypeControl. Tried the following function CustomGMapTypeControl() {} CustomGMapTypeControl.prototype = new GMapTypeControl() CustomGMapTypeControl.prototype.setButtonStyle_ = function(button) { button.style.backgroundColor = "red"; } but the setButtonStyle_ function doesn't even get called. Any solutions for this?

• how to create english language dictionary application with python (django)?

  - by sintaloo

  Hi All, I would like to create an online dictionary application by using python (or with django). It will be similar to http://dictionary.reference.com/. My question is (1) Are there any existing open source python package or modules or application which implements this functionality that I can use or study from? (2) If the answer to the first question is NO. which algorithm should I follow to create such web application? Can I simply use the python built-in dictionary object for this job? so that the dictionary object's key will be the english word and the value will be the explanation. is this OK in term of performance? OR Do I have to create my own Tree Object to speed up the search? or any existing package which handles this job properly? Thank you very much.

• How would you code this: Grid-breaking shapes

  - by BeachRunnerJoe

  I'm a person that learns best from example. Currently, I'm diving into the field of Web Development after fifteen years of developing desktop apps. I'm still getting used to all the web technologies used for developing modern web sites and everywhere I look, I see cool little UI elements and question how they're implemented. So I thought I'd ask you, the web experts...the wexperts :) What are some straight forward or creative ways you could code this grid-breaking arrow... The basic layout for this page looks like... What would the html/css code look like? Would you split the image into multiple images or could you use a single image? I'm sure this is a really simple concept and it completely boggles me. I'm sorry if this is a strange question, remember I'm a noob! :) Thanks in advance for all your help! Here's a link to the original tutorial where I found these images

• Which database should I use for best performance

  - by _simon_

  Hello, I am working in Visual Studio 2005, .NET 2.0. I need to write an application, which listens on COM port and saves incoming data to a database. Main feature: save incoming data (series of 13-digits numbers), if this number allready exists, then mark it as double. For example, there could be these records in database: 0000000000001 OK 0000000000002 OK 0000000000002 Double 0000000000003 OK 0000000000004 OK I could use SQL database, but I don't know if it is fast enough... Database should be able to store up to 10.000.000 records and write up to 100 records per minute (so it needs to check 100 times per minute if this record allready exists). Which database should I use? Maybe the whole database would need to be in RAM. Where could I learn more about this? Thanks

• django image managment

  - by Andrey

  I'am new in django. In my project I'am working with images. I don't know how to organize the management of images. I need to dynamically upload the pictures and resize them. First question - what is the best way to dynamically upload images with progress bar and without flash? I found this and this, but I believe there is a better way. Second question. I have to save one image in different sizes. I won't use these thumbnails on my pages, but another application will. Many clients could upload images at the same time. This means that I can not resize all the images at the same time. How should I organize this process? Is there are a better ready-to-use solution for image management issue?

• Compress small strings, With what to create external dictionary?

  - by Chris

  I want to compress much small strings (about 75-100 length c# string). At the time the dictionary is created I already know all short strings (nearly a trillion). There will no additional short strings in future. I need to extra exactly one string without decompress other strings. Now I am looking for a library or the best way to do the following: Create a dictionary using all strings I have Using this dictionary to compress each string a way to compress one string using the dictionary from 1. I found a good related question, but this is not c# specific. Maybe there is something for c# I do not know, or a fancy library or someone has already done that. That is the reason I ask this question.

• My webpage ignores changes in CSS file

  - by Pavel

  No matter what I change in my .css file, the page remains the same - what's more, neither changing the link tag so that it points to another .css file nor deleting it completely makes no difference. Other changes in html code are applied. The sourcecode of the webpage shows everything as it should be. This behavior started when I redirected the link tag from previous file to the one I use now (plus there have been some changes in the tag while this problem occured, to test the behavior of my webpage); changes in neither file affect the page. For the first time when this happened, this was caused by copies of head tag in included chunks of code (for header, left menu etc. - their head part overrode the head part of the main page) and the problem was solved by removing these redundant heads from these files. But it happened again when I changed the link tag for the next time. I couldn't find any head parts in my included files, but the problem lasts (only solution I can see now is to delete the included files and copy the code directly to the file, but this would mean lots of redundant code). How can I solve this problem, so that my page response to changes in .css files without increasing redundancy? How to ensure that I can change the link to .css file just on one place with no such problems? Do I have to unload the CSS file somehow? I saw this problem both in Firefox and in Chrome. I use PSPad to write the code, just in case it would play role. EDIT: I have cleared browser cache now, and I changed the link to .css files from one to another before, but nothing helped. Now I accept the best answer saying the problem is in caching and I start a related question to find out how to solve the caching issue. If the other question's answers would say that in this case I can be sure that problem isn't in caching (very unlikely, but fail of ordinary methods of caching-problems-solving is unlikely too), I'd update this question and start searching for other possible problems, but now the message seems to be clear: when webpage ignores changes in .css files, caching is to blame.

• How do I create custom Controls for my VS2005 toolbox?

  - by end-user

  Ok, this question might more about design theory. I have successfully created controls that show up in my toolbox, so I'm pretty sure I have the process right. Also, my "AutoToolboxPopulate" is set to true, so things are showing up as I create them. My question is this: I'm sub-classing a native Control for specialized use. When I derive my class from an exposed concrete class, such as BulletedList, my custom Control appears in my Toolbox. However, when I drop it back to the parent, such as ListControl, my Control is not listed (actually it's grayed out when I "List All"). What am I missing?

• Can you Borrow a PDF?

  - by WeNeedAnswers

  What are the legalities of letting someone borrow a book that you have purchased that so happens to be in PDF format with no DRM? I know that I can lend a printed book to someone and this not infringe copyright, but a pdf? I know that the thought police are going to be on my case about "no one here is a legal expert" or the "question can't be answered" or "controversial", But I would like to have the opportunity to at least surface the issue, and allow people to comment. I am not looking for point scoring on this, or even an answer, but as stackoverflow has a rather large technical savvy audience that would appreciate the question I think that it could be the next hurdle that will stop technical progress.

• read successive frames OpenCV using cvQueryframe

  - by AtharvaI

  Hi all I have a basic question in regards to cvQueryFrame() in OpenCV. I have the following code: IplImage *frame1,*frame2; frame1 = cvQueryFrame(capture); frame2 = cvQueryFrame(capture); Now my question is: if frame1 is a pointer to the first frame, is frame2 a pointer to the 2nd frame? So will the two cvQueryFrame() calls read successive frames? I thought I'd check myself first but the pointers frame1,frame2 seem to have the same hex value. :s I just need to capture two frames at a time and then need to process them. Thanks in advance

• Annotation based data structure visualization - are there similar tools out there?

  - by Helper Method

  For a project at university I plan to build an annotation based tool to visualize/play around with data structures. Here's my idea: Students which want to try out their self-written data structures need to: mark the type of their data structures using some sort of marker annotation e.g. @List public class MyList { ... } so that I know how to represent the data structure need to provide an iterator so that I can retrieve the elements in the right order need to annotate methods for insertion and removal, e.g. @add public boolean insert(E e) { ... } so that I can "bind" that method to some button. Do similar applications exist? I googled a little bit around but didn't find anything like that.

• What motivates people to learn a new programming language?

  - by szabgab

  There are plenty of question asking Which Programming Language Should I Learn? but I have not found an answer yet to the question what really motivates people to learn a specific new language?. There are the people who think they should learn a new language every year for educational purpose. How do they decide on the languages to be learned? Then I guess there are people who learn a new language because people around them told it is a fun language and they can build nice things with it. Of course if the current job requires it people would learn a new language but I think if the language seems to have a potential to earn money (e.g. There are plenty of jobs in Java or ObjectiveC can be used to write apps for the iPhone and make money). So why are you learning a new language or why have you learned the languages you know?

• Detecting metadata-only read requests in windows filesystem

  - by HyLian

  Hello, I'm developing a kind of filesystem driver. All of read requests that windows makes to my filesystem goes by the driver implementation. I would like to distinguish between "normal" read requests and those who want to get only the metadata from the file. ( Windows reads first 4K of the file and then stop reading ). Does Windows mark this metadata reads in some way? It would be very useful in order to treat that two kind of operations in a different way. In a typical CreateFile call, we have AccessMode, ShareMode, CreationDisposition and FlagsAndAttributes parameters ( being DWORD ), i'm not sure if it's possible to extract some clue of the operation requested. Thanks for reading :)

• Send serialised object via socket

  - by RubbleFord

  Whats the best way to format a message to a server, at moment I'm serilising an object using the binaryformatter and then sending it to the server. At the server end its listening in an async fashion and then when the buffer size recieved is not 100% it assumes that the transfer has complete. This is working and the moment, and I can deserialise the object at the other end, I'm just concerned that if I start sending async this method will fail has message's could be blurred. I know that I need to mark the message somehow as to say that's the end of message one, this other bit belongs to message 2, but I'm unsure of the correct way to do this. Could anyone point me in the right direction and maybe give me some examples? Thanks

• this == null; surely not, but yes

  - by pm100

  I would have said that this will segfault but apparently not #include <stdio.h> class foo { public: bool thingy() {return this == 0;}; }; int main() { foo *f = 0; if(f->thingy()) printf("eating hat\n"); } I just expect that 0-xxx will never work. I assume that if we had to do some vtabling it would fail; obviously cannot access any member variables either edit; sorry - no question there. THe question is "are you surprised like me?" and it seems the answer is yes. even though nobody said yes. I got a) of course this will work b) of course this will never work c) it is undefined behavior; your mileage will vary

• Is `auto int i` valid C++0x?

  - by Motti

  In answering this question the question arose as to whether the traditional C meaning of the keyword auto (automatic storage) is still valid in C++0x now that it means type deduction. I remember that the old meaning of auto should remain where relevant but others disagreed. auto char c = 42; // either compilation error or c = '*' Looking at compilers I see the current division. Old meaning of auto is no longer allowed VS10 g++ Old meaning of auto is used where relevant Comeau Do you know which is the correct behaviour?

• Third Party Libraries and Technologies very Java Programmer must be aware of?

  - by kunjaan

  I agree that this is a very subjective question but as a student of Java , I get suggested good libraries and technologies for Java by my mentors at work. For example, I was not aware of Google Guice for Dependency Injection, awesomeness of Java Reflection APIs, ORMs like Hibernate or stuffs you could do with libraries like Hadoop. I want to collect and share some of the libraries that exemplifies good java programming (so that beginners like me could code walk and emulate the coding practice), teach unique concepts to Java (for example Dependency Injections or ORM) and/or are really interesting libraries that a student like me would get to do interesting projects on (eg. Hadoop). I redited this question 3 times to make it more specific : ). I am sorry if I am really not clear in my intentions. But some kind of a list of good concepts and third party libraries for Java could really help some of my intern friends here at work. Thank you.

• Writing loops with i++ or ++i [duplicate]

  - by Nonesuch

  This question already has an answer here: Why use ++i instead of i++ in cases where the value is not used anywhere else in the statement? 6 answers format of for loops 31 answers I have a question about writing loops. I always begin with (int i=0; i<10; i++) But I see many experts begin with (int i=0; i<10; ++i) Is there there any real difference, or they are same? Of course, I know the difference between pre-increment and post-increment. I mean which one I should use when writing the loop? or it depends. Thanks!

• Common optimization rules

  - by mafutrct

  This is a dangerous question, so let me try to phrase it correctly. Premature optimization is the root of all evil, but if you know you need it, there is a basic set of rules that should be considered. This set is what I'm wondering about. For instance, imagine you got a list of a few thousand items. How do you look up an item with a specific, unique ID? Of course, you simply use a Dictionary to map the ID to the item. And if you know that there is a setting stored in a database that is required all the time, you simply cache it instead of issuing a database request hundred times a second. I guess there are a few even more basic ideas. I am specifically not looking for "don't do it, for experts: don't do it yet" or "use a profiler" answers, but for really simple, general hints. If you feel this is an argumentative question, you probably misunderstood my intention.

• Can I preload multiple video resources to load in the same HTML5 <video> element?

  - by Sergio1132

  I'm working out details on a web application which involves the sequential loading of a long series of (very short) video clips, one after the other, with occasional input from the user establishing new directions for which video clips to load. I would like to be able to have the browser preload the video clips five at a time. However, the way that we currently have the site working is by means of a single video element which is having its src attribute continually updated through JavaScript. So, my question is, is there a straightforward way I can get the browser to preload multiple video clips even though I am ultimately loading them all (one at a time) into the same video element? This is my first question here, so let me know if I could have phrased that better...

• ReportViewer with DataSets

  - by bearrito

  I have a question about the following architecture. I am importing my business objects into my client using WCF. Due to the complexity of the business objects ( nested hierarchies ) I want to flatten out my business objects into a dataset/datatable. There are many more tutorials and how-to on successfully using datatables in a report than with a business object so I am pretty attached to this idea. My question is what sort of DataSet should I use? Strongly typed or not? If strongly typed how do I import my business objects into the Datatables?

• C++ - How to efficiently find out if any string in a vector can be assembled from a set of letters

  - by Francisco P.

  Hello, everyone! I am implementing a text-based version of Scrabble for a college project. I have a vector containing around 400K strings (my dictionary), and, at some point in every turn, I'm going to have to check if there's still a word in the dictionary which can be formed with the pieces in the player's hand. I'm checking if the player has any move left... If not, it's game over for the player in question... My only solution to this is iterating through the string, one by one, and using a sub-routine I have to check if the string in question can be formed from the player's pieces. I'll implement a quickfail checking if the user has any vowels, but it'll still be woefully inefficient. Any suggestions? Thanks for your time!
