• How do I use global resources in WPF?

  - by Banford

  I have a WPF application which I would like to use some static resources in. I have created a Resource Library XAML file which contains a resource. I have also added a string into the Resources of the project through the Properties panel. I assumed I could just use these resources with the binding expression: {StaticResource ResourceName} But visual studio is telling me the resources are not found. Do I have to include some form of reference in my XAML? The examples I have seen only include resources locally such as: <Window.Resources>, <Page.Resources> etc I don't want to include the resources locally because I want them to be available to multiple parts of the application.

• Web design process with CSS - during or after?

  - by SyaZ

  Which is the better practice? Add CSS during web designing you can see the result (or close) as early as possible and make required changes. You also know how many divs or spans you might need (eg to make curved cross-browser hover background). But as you add more and more components to the page sometimes things get hack-ish as you need to patch here and there to get the exact design required. Add CSS after finishing page design you can see the page overall structure as it is well, without styles. You get to see how accessible your site is, and modify it right away if it's not good enough (unlike the former case where you may break multiple CSS rules). Plus after you finished it, you only need to spend most of the time to alter only the CSS file, which is good to get the momentum going. Granted I have never tried the latter approach, but am seriously considering it for my next project if I can see convincing reasons -- or if it's no good at all. Thanks.

• C# Proxy, what is the best way to do this?

  - by Kin

  I'm writing a proxy using .NET and C#. It has a couple of functions that it needs to fulfill. I haven't done much Socket programming, and I am not sure the best way to go about it. Should I use Synchronous Sockets, Asynchronous sockets? Please help! It must... Accept Connections from the client on two different ports, and be able to receive data on both ports at the same time. When a connection is made on a port, it must immediately connect to the server, and start sending data as it receives it from the client to the server. Packets must be forwarded in the order they are received, exactly as they were received. It needs to be as low latency as possible. I don't need the ability for multiple clients to use the proxy, but it would be a nice feature if its easy to implement.

• magic records being deleted

  - by chris

  i have customised oscommerce to pull in a csv file of products, delete anything thats not with an image/proper description/proper title gets removed. The import runs on a cron job basis pulling information from a supplier, it hasnt run since yesterday but a product has disappeared- Anyone who has used oscommerce will know that, product information is stored over multiple tables. example is- products product_description and so on. the thing that has got me that the information is deleted from the product table but not from the product_description table. The product that is being deleted is a manually input one which carries a special tag/prefix on the model item of the product table. Therefore shouldn't be touched at all. Am clueles as what is going on. Is there mysql integrity checks deleting records? could there be another plugin working on oscommerce?

• VB.Net 2008 Chrome or Firefox control

  - by AndyD273

  I'm trying to figure out a way to have multiple sessions at the same website at the same time. I've been using the SHDocVw.InternetExplorer control in Visual Studio 2008 to open a web browser and log in, but at times we need to use a separate login. I haven't found a way to do this using just internet explorer (it just uses the credentials of the first login), so I figure if I can find a similar control for another brower that allows DOM level access then I can just use that. If anyone knows of anything I can try that would be very helpful.

• How can I find all attributes with single quotes in a Sublime Text 2 document and replace with double quotes?

  - by Brandon Durham

  I'm feeling particularly nit-picky today. I'm working in some HTML docs that have single quotes around all attribute values through the docs, like this: <div class='classone classtwo'> I'd love to be able to do a find-and-replace in each doc and replace with double quotes, like this: <div class="classone classtwo"> Many elements in the document will have multiple attributes: <div class='classone classtwo' data-scripts='lazyload'> And some will have the correct double quotes: <div class='classone classtwo' data-scripts="lazyload"> What's the best way to replace all single quotes wrapping values with double?

• How to make g++ search for header files in a specific directory?

  - by Bane

  I have a project that is subdivided into a few directories with code in them. I'd like to to have g++ search for header files in the project's root directory, so I can avoid different include paths for same header files across multiple source files. Mainly, the root/ directory has sub-directories A/, B/ and C/, all of which have .hpp and .cpp files inside. If some source file in A wanted to include file.hpp, which was in B, it would have to do it like this: #include "../B/file.hpp". Same for another source file that was in C. But, if A itself had sub-directories with files that needed file.hpp, then, it would be inconsistent and would cause errors if I decided to move files (because the include path would be "../../B/file.hpp"). Also, this would need to work from other projects as well, which reside outside of root/. I already know that there is an option to manually copy all my header files into a default-search directory, but I'd like to do this the way I described.

• IN statement performance in PostgreSQL (and in general)

  - by Vasil

  I know this has probably been asked before, but I can't find it with SO's search. Lets say i've TABLE1 and TABLE2, who should I expect the performance of a query such as this: SELECT * FROM TABLE1 WHERE id IN SUBQUERY_ON_TABLE2; as the number of rows in TABLE1 and TABLE2 grow and id is a primary key on TABLE1. Yes, I know using IN is such a n00b mistake, but TABLE2 has a generic relation (django generic relation) to multiple other tables so I can't think of another way to filter the data. At what (aproximate) ammount of rows in TABLE1 and TABLE2 should I expect to notice performance issues because of this? Will performance degrade linearly, exponentially etc. depending on the number of rows?

• The use of GROUP BY in MySQL

  - by Gustav Bertram

  I'm fishing for a comprehensive and canonical answer for the typical "mysql group by?" question. Here is some sample data: TABLE A +------+------+----------+-----+ | id | foo | bar | baz | +------+------+----------+-----+ | 1 | 1 | hello | 42 | | 2 | 0 | apple | 96 | | 3 | 20 | boot | 11 | | 4 | 31 | unicorn | 99 | | 5 | 19 | pumpkin | 11 | | 6 | 88 | orange | 13 | +------+------+----------+-----+ TABLE B +------+------+ | id | moo | +------+------+ | 1 | 1 | | 2 | 99 | | 3 | 11 | +------+------+ Demonstrate and explain the correct use of the GROUP BY clause in MySQL. Touch upon the following points: The use of MIN, MAX, SUM, AVG The use of HAVING Grouping by date, and ranges of dates Grouping with an ORDER BY Grouping with a JOIN Grouping on multiple columns Bonus points for references to other great answers, the MySQL online manual, and online tutorials on GROUP BY.

• Using Enums that are in an external dll C#

  - by user1443233

  I have a project I am working that will involve creating one DLL that will be used across multiple other sites. Inside this DLL we need to reference about 10 Enums. The values of these Enums however will be different for each site the DLL is used on. For example: MyBase.dll may have a class MyClass with an attribute of type MyEnum. MyBase.dll is then referenced in MySite. MyStie will also reference MyEnums.dll which will contain the values for the MyEnum type. Is there any way to accomplish this? While building MyBase.dll, I know what enums will exist in side of MyEnums.dll. The problem is I cannot build MyBase.dll without specifically referenceing the MyEnums.dll, which is not created until the MyBase.dll is used in a specific project. I hope that makes sense and hope I can find an answer here. Thanks.

• How do I avoid nesting forms when offering inline editing of lists with checkboxes for mass updates.

  - by adam

  A lot of sites offer the ability to edit lists of items inline as well as allowing multiple items to be selected via checkboxes and have an action performed all at once e.g. delete, mark as spam etc. But how do you implement this without violating html rules. I need one form for the checkboxes with individual submit_tags for the mass actions. But after a user clicks on an item in the list, another form via Ajax will be inserted within the checkbox form. How do I avoid doing this? I'm using rails and jQuery.

• Why will show() only work for fields that are hidden using inline css?

  - by Chris

  I am hiding an element using inline css, like so: <span class="hidden-nojs" style="display:none">Some text</span> Next I use jQuery to show the element, like so: $(".hidden-nojs").show(); This works great. As soon as I remove the inline css and put display:none on the external css stylesheet for the hidden-nojs class, it stops working. This is what I wrote in the external stylesheet: .hidden-nojs { display: none; } I'm assuming that the external stylesheet loads after the jQuery has already run? This is somewhat annoying as I would like to hide multiple elements with css and would like to avoid using inline css. Why will show() only work for fields that are hidden using inline css? How can I fix this problem?

• Resources for looking up differences in rendering behavior between web-browsers and browser bugs

  - by ICodeForCoffee

  I recently encountered a printing issue in Firefox that eventually turned out to be a problem with the fieldset tag we wrapped the entire page in. (Bugzilla: Bug 471015) All browsers have their own rendering quirks and issues, but it can be very hard to know what's causing different behaviors. Sure, you can Google, but that's often taking a shot in the dark about what you think is causing the problem. It also doesn't stop you from having to sort through multiple complains about the same behavior before you find someone who has the issue your looking for. Are there any websites out there that let you search for rendering behavior issues by browser version, browser function, css tag, or html tag? I've seen this SO Question, Wanted: Resource for documented Cross-Browser differences, but I'd like to find something more detailed that includes browser bugs.

• Authenticating mssql users through different logins

  - by Sebastian Ferreyra

  I'm developing a new node.js based frontend for an old intranet site using mssql server and Classic ASP. Both the new and the old site will coexist during the transition phase and both must access the same mssql server using the same database principals. The old ASP/IIS site uses integrated windows login. The new node-based frontend has to use sql server based logins/principals (edit: while the IIS/ASP site must keep using Windows server principals) and all existing database users/principals must keep working wherever they login from. From reading around, it appears that a database principal can not be assigned to multiple server principals, therefore it seems unlikely there's a simple solution to this. I'd like to know if anybody has had to deal with a similar situation before and how they've gone about it.

• GUI system architecture?

  - by topright

  I'm designing GUI (graphical user interface) system for a game engine (C++). Idea is to create a heirarchy of GUI controllers like Focusable, Hoverable, Dragable etc. Every GUI component can attach multiple controllers, they modify component's behaviour. I think it gives flexible system and protects from code duplication. Different instances of the same GUI class can have different complex behaviours (may be, even change it dynamically), so this approach looks practical. The other choice is to add focused, hovered, dragged etc. flags in the base GUI component class. It looks like overhead and not that flexible. Another solution is to use Decorator pattern and wrap objects with FocusDecorator, HoverDecorator etc. Maintaining such system looks a bit harder. Question: What are pitfalls in my solution? May be you have seen a better approaches in GUI systems? What are the best ways of implementing such flexible complex system?

• Data mining logs to locate a bug

  - by gooli

  I'm working on a data distribution application which receives data from a source and distributes that data to multiple target application. After successfully distributing several messages each second for 8 days, it missed a single message and did not deliver it properly to the clients. As I was looking at the logs I tried to find something there that was special for the time the miss happend - either in the data, its rate or some other condition but couldn't find anything. Is there any data mining technique I can use to identify how that specific event differs from other events?

• Custom User Management for Google App Engine Java

  - by Gopi

  I am using GAE Java for a multi-user application. There are multiple users with different roles. Each user can login, do some operations and logout. The business restricts me from using Google User Service and I need to implement my own for authentication and session management. Can anyone please share with me how should I go about implementing my own user management? I have read its very tricky to implement own user management. Any pointers in terms of best approaches/ design / existing frameworks if any ? I could see some similar posts but they are for python.

• Mapping words to numbers with respect to definition

  - by thornate

  As part of a larger project, I need to read in text and represent each word as a number. For example, if the program reads in "Every good boy deserves fruit", then I would get a table that converts 'every' to '1742', 'good' to '977513', etc. Now, obviously I can just use a hashing algorithm to get these numbers. However, it would be more useful if words with similar meanings had numerical values close to each other, so that 'good' becomes '6827' and 'great' becomes '6835', etc. As another option, instead of a simple integer representing each number, it would be even better to have a vector made up of multiple numbers, eg (lexical_category, tense, classification, specific_word) where lexical_category is noun/verb/adjective/etc, tense is future/past/present, classification defines a wide set of general topics and specific_word is much the same as described in the previous paragraph. Does any such an algorithm exist? If not, can you give me any tips on how to get started on developing one myself? I code in C++.

• Django filter with two constraints on related model

  - by BJ Homer

  I have a django app with models as follows: A Question model An Answer model, with a ForeignKey back to the Question. (A question can have multiple answers.) A Flag model, with a ForeignKey to the Answer. (An answer can be flagged as inappropriate.) All of the above also have a user field, defining the user that created that object. I'm trying to get a list of all Questions with answers from the current user which have been flagged. I tried this: Question.objects.filter(answer__user=user).\ filter(answer__flag__isnull=True).distinct() … but I believe that will return a list of Questions with answers from the current user and with answers which have been flagged, but will not necessarily guarantee that it is the user's answer that has been flagged. Is there an easy way to do this? Basically, I want to make the answer part of the filter refer to the same answer on both of them. Please let me know if something is unclear.

• What should be the image resolution for Nexus One or Droid?

  - by sunil

  Hi, As Android supports multiple devices from different manufacturers there are different screen resolutions supported. The table that is available at http://developer.android.com/intl/fr/guide/practices/screens_support.... is not very clear to me. It shows WVGA and FWVGA in MDPI for Large Screens and HDPI for Normal screens. So, if the image is kept in drawable-mdpi and its resolution is 320 * 480 then which image will be taken by Large Screens device of MDPI. Moreover, there are two screen resolutions for HDPI i.e. 480 * 800 and 480 * 854. So, with what screen resolution the image should be built. I want to place the background image which looks distorted in WVGA emulator since its resolution is 320 * 480. I have read about nine patchable images but I think they are better for button images and edittext images so that they can stretch according to the data in it. Can someone please guide me in this? Regards Sunil

• Exception handling in Boost.Asio

  - by Alex B

  Boost.Asio documentation suggests the following exception handling pattern: boost::asio::io_service io_service; ... for (;;) { try { io_service.run(); break; // run() exited normally } catch (my_exception& e) { // Deal with exception as appropriate. } } The problem with it is that the context of exception is lost at the point when it's handled. For example, if I have multiple socket sessions going on, I don't know which one caused the exception to be thrown. What would be a better way to handle the exceptions from asynchronous handlers without wrapping them in try/catch blocks?

• basic question with a dtd

  - by voodoomsr

  i need an element with the characteristics <!ELEMENT section ((comment*)|definition|(comment*))> but that is ambiguous, i get the next message in visual studio Multiple definition of element 'comment' causes the content model to become ambiguous. A content model must be formed such that during validation of an element information item sequence, the particle contained directly, indirectly or implicitly therein with which to attempt to validate each item in the sequence in turn can be uniquely determined without examining the content or attributes of that item, and without any information about the items in the remainder of the sequence. So how can i write correctly that? the correct structure is one definition surrounded by possibles comments elements.

• Programmatically changing code files

  - by Carra

  I'm changing our webservices to an async model. And for that I have to change over a hundred methods. Doing it manually is one (unappealing) option. Is there no way to programmatically parse & change multiple functions/code files? Example: [Webmethod] public void MyWebservice (string parameter1, string parameter2, string parameter3) { //Logic here } And change this to: public void InternalMyWebservice (string parameter1, string parameter2, string parameter3, AsyncCallback callback) { //Logic here } [Webmethod] public void BeginMyWebservice (string parameter1, string parameter2, string parameter3, AsyncCallback callback, object asyncState) { //Queue InternalMyWebservice in a threadpool } public void EndMyWebservice(IAsyncResult asyncResult) { //Set return values } It's basically the same thing I have to do for each webservice. Change the name to "InternalX", add a parameter and create the begin & end method.
