• SEO Friendly URLs where the phrase used may change in Rails

  - by Newy

  Say I have http://www.mysite.com/I-Like-Cheeseburgers and I want that to point to Item with id 3. Sometime later, I change the name of the item, and now its http://www.mysite.com/I-Like-Hamburgers (and perhaps many more times). I want all these URLs to remain pointing to Item 3. Is it efficient to simply keep a table of [strings,item_ids] and do a lookup on this? Is there a better way?

• Splash Screen Example

  - by Kovu

  Hi, I only want a simple Splash Screen Example. Get the Code, Insert my picture, add 2 lines of code to load and finish. But all I can google is so complex, that is too much. I only want a form with a picture that goes more and more transparent until it hides automaticly and my window is shown. I tried the "prettygoodsplashscreen" from Codeproject, but don't work for me. Lang is c#.net 2.0

• ASP.NET MVC routing and paths is js files

  - by HiveHicks

  Hello, we're facing a problem now. We have a pretty big page with a loooong inline script, which does all the work. We now want to obfuscate it and use it as a separate .js file. But the problem is that we have paths which are generated by Url helper (Url.Content()). So what is the best way to separate js file from the page and not using hard-coded path strings?

• C++ error message output format

  - by sub

  If I want to trigger an error in my interpreter I call this function: Error( ErrorType type, ErrorSeverity severity, const char* msg, int line ); However, with that I can only output Name error: Undefined variable in line 1 instead of Name error: Undefined variable 'someVariableName' in line 1 I'm working entirely with strings (except for the error messages as they all are constant at the moment), so sprintf won't work. What is the best way to create an efficient error function that can output a constant message combined with a string that describes which object, e.g.: a non-existing variable, triggered the error?

• Flex repeater - toggle sibling component visibility on checkbox change

  - by steve_c

  I have a Flex repeater that has a complex item template. When a checkbox is clicked, I need to toggle the visibility of a sibling button contained in the same repeater template. Since I can't add binding expressions to event handlers, I can't pass in the repeater item's index. How can I access sibling components inside a repeater item?

• Which one has a faster runtime performance: WPF or Winforms?

  - by Joan Venge

  I know WPF is more complex an flexible so could be thought to do more calculations. But since the rendering is done on the GPU, wouldn't it be faster than Winforms for the same application (functionally and visually)? I mean when you are not running any games or heavy 3d rendering, the GPU isn't doing heavy work, right? Whereas the CPU is always busy. Is this a valid assumption or is the GPU utilization of WPF a very minor operation in its pipeline?

• In elisp is there a difference between the regex [\\]documentclass and \\documentclass?

  - by mcheema

  I was playing around with the rx function for generating regular expressions from sexps in ELISP but couldn't figure out how to generate the regular expression "\\documentclass" for use in org-export-latex-classes: (rx "\\documentclass") (rx "\\" "documentclass") (rx (char "\\") "documentclass") Which when evaluated give respectively the following outputs: "\\\\documentclass" "\\\\documentclass" "[\\]documentclass" Is "\\documentclass" equivalent to "[\\]documentclass"?---I think it is, but am not sure. Can I generate the former using rx? Edit: Whilst the question was valid I realize my motivation was not; because org-export-latex-classes use strings not regular expressions.

• How do I escape backslashes in JSON?

  - by peteb

  I am using Firefox's native JSON.parse() to parse some JSON strings that include regular expressions as values, for example: var test = JSON.parse('{"regex":"/\\d+/"}'); The '\d' in the above throws an exception with JSON.parse(), but works fine when I use eval (which is what I'm trying to avoid). What I want is to preserve the '\' in the regex - is there some other JSON-friendly way to escape it?

• Fast data structure for small sets

  - by thr

  I'm in need for a data structure that can handle small sets (10-20 strings, at most 50, of varying length) very fast. False positives is ok, but false negatives are not. The last requirement makes bloom filters seem like a good fit, but I'm not sure about their speed, any other recommendations?

• VB6 code for Reading/Writing Windows Registry values

  - by Clay Nichols

  I'm looking for a good example of reading and writing to the Windows Registry using VB6. Yes, I know there are lots of mediocre examples. I spent an hour googling and testing. Some were incredibly complex, others had only some of the functions, and almost none of it had been vetted in any way (voted on). Since Stack Overflow is intended to the canonical location for answers to programming questions, it seems reasonable to post it here.

• how can I easily upload outlook contacts into my web application?

  - by Angela

  Hi, I am trying to find a way for our users to very easily upload their outlook contacts into our web application (mysql database). I'm not sure where to begin. I've seen various tools which are pretty complex. I am open to existing third-party solutions, but my hope is that there is something which is very simple to use or build. Thanks. PS: Ideally, it would not involve using visual basic.

• Script-Based Configuration in .net?

  - by Michael Stum

  One of the downsides of web.config/app.config is that it's just Magic Strings everywhere, since it's just an XML file. Interpreted languages like PHP or Ruby have the advantage that the configuration is just code that is executed. In .net, doing stuff in code requires a redeployment, which defeats the purpose. Now, before I build my own web.config replacement based on Boo or PowerShell I wanted to know if there is an existing one?

• Building a balanced binary search tree

  - by Znarkus

  Hi! Is there a method to build a balanced binary search tree? Example: 1 2 3 4 5 6 7 8 9 5 / \ 3 etc / \ 2 4 / 1 I'm thinking there is a method to do this, without using the more complex self-balancing trees. Otherwise I can do it on my own, but someone probably have done this already :)

• Interpreter typing in C

  - by typus

  I'm developing an interpreter and I have some questions to it. I recently saw a small C interpreter that used a very simple struct like the below for all its objects/values in the language: struct Object { ubyte type; ubyte value; }; This struct can hold strings, integers, bools and lists (I think) used in the language the interpreter is working with. How can you get this Object struct to hold all these types?

  Does anyone know how to construct a POST DATA body in VBA? I'm trying to upload rather lengthy strings via a post call using the "Microsoft.XMLHTTP" object. I'm not tied to using that object for making the HTTP request either.
