  • Working with the IE cache from C# & WPF

    - by Eric
    I'm writing a program in C# using the WPF framework. I need to display images, and I'd like to cache them to avoid downloading them constantly. I can code my own cache, however, IE already has a caching system. I can find code to read entries out of the IE cache, however I've found nothing dealing with the issue of adding items to the cache. Is there a good way to do it, or should I just implement a separate cache?

  • is unicode( codecs.BOM_UTF8, "utf8" ) necessary in Python 2.7/3?

    - by Brian M. Hunt
    In a code review I came across the following code that contains the following: # Python bug that renders the unicode identifier (0xEF 0xBB 0xBF) # as a character. # If untreated, it can prevent the page from validating or rendering # properly. bom = unicode( codecs.BOM_UTF8, "utf8" ) r = r.replace(bom, '') This is in a function that passes a string to Response object (Django or Flask). Is this still a bug that needs this fix in Python 2.7 or 3? Something tells me it isn't, but I thought I'd ask because I don't know this problem very well. Thanks for reading.

  • Open source equivelants to VS / web reference proxy class autogen?

    - by seraphym
    As an ASP.NET developer, I'm used to working with how VS/C# transparently autogens proxy classes for web references (yes, I know, we're spoiled), but now that I'm creating documentation for more than one coding platform I'm trying to discover what the equivelant to that is in any other framework. So is there a similar way to work transparently with web reference proxy classes for say, RoR, PHP, and Python? And if there's nothing integrated, are there tools you recommend to autogen the proxy classes, or do you recommend to roll custom classes?

  • Organize routes in Node.js

    - by NilColor
    Hello! I start to look at Node.js. Aslo I'm using Express. And I have a question - how can I organize web application routes? All examples just put all this app.get/post/put() handlers in app.js and it works just fine. This is good but if I have something more than simple HW Blog? Is it possible to do something like this: var app = express.createServer(); app.get( '/module-a/*', require('./module-a').urls ); app.get( '/module-b/*', require('./module-b').urls ); and // file: module-a.js urls.get('/:id', function(req, res){...}); // <- assuming this is handler for /module-a/1 In other words - I'd like something like Django's URLConf but in Node.js.

    - by niko
    Hi, I have the DataTable with following columns: id, Name, Description, ParentId and would like to create a WPF control (.NET 4.0 framework) which implements a combobox which displays the names which are bound to values of id.

  • sql server: losing identity column on export/import

    - by Y.G.J
    Recently I started dealing with SQL Server, my previous experience was in MS-Access. When I'm doing an import/export of a db, from the server to my computer or even in the server, all column with primary key loose the key. Identity is set to false and even bit is not set to the default. How can I can I use an import/export job to make an exact copy of the db and its data? I don't want to have to perform a backup and restore every time I want the same db somewhere else, for another project, etc. I have read about "edit mapping" and the checkbox but that did not helped with the identity specification... and what about the primary key of the tables and the rest of the things?

  • How to remove .htaccess virus? [closed]

    - by bleepingcrows
    Possible Duplicate: My server's been hacked EMERGENCY First time posting so bear with me please! My friend's site has been hacked and the .htaccess file (which I really know nothing about) has been injected with a malicious redirect that forces search engines to the see the site as a "harmful website." If you look at the .htaccess file you can see it's Russian or at least ends in .ru. Seeing as I know very little about this stuff, I simply tried to restore the good .htaccess file back with his host. This doesn't work as the virus just recreates the infected .htaccess file. When I searched through the rest of his directories, I can see the same bad .htaccess file in most of the folders. I can't seem to help him get rid of this virus.

  • How can I turn off flash fill automatically in Excel 2013?

    - by user3480643
    Flash fill breaks a lot of things in older excel documents. It causes maddeningly slow transfers from cell to cell after updating. I am trying to find a way to turn off "flash fill" in Excel 2013 automatically before rolling the product out to the rest of the staff in my company. Is there (preferably) a registry key that I can apply or a switch that I can include during the install that will turn this option off? Here is an image of the setting that I am looking to turn off: I haven't been able to find any documentation online about turning this off, other than this one page from MS: http://office.microsoft.com/en-ie/excel-help/turn-flash-fill-on-HA104043292.aspx

  • How to convert excel individual cell values to percentage change values over time

    - by cgalloway
    I have two years of excel data showing daily share prices of a particular stock. I want to change those values to show percentage change (on a daily basis) from the zero date (ie the first day of the two year period). I know that the formula for showing daily percentage change would be (second day/first day -1) and that I can click and drag on that formula to extend over the rest of the two-year time period. The formula I want would be, basically, (each day/first day-1). Is there an easy way to automate the script so I dont have to type it out 730 times?

  • What is the role of the Router Object in MVC based frameworks

    - by Saif Bechan
    In most MVC based framework I see a router object. If I look at it splits up the uri and decides what controller should be used, and which action should be fired. Even though this makes a lot of sense, I can not give this a place in the MVC patern. Is splitting up the uri not the job of the controller. And then the controller should just decide which class and function to run.

  • Server Requirement and Cost for an android Application [duplicate]

    - by CagkanToptas
    This question already has an answer here: How do you do load testing and capacity planning for web sites? 3 answers Can you help me with my capacity planning? 2 answers I am working on a project which is an android application. For my project proposal, I need to calculate what is my server requirements to overcome the traffic I explained below? and if possible, I want to learn what is approximate cost of such server? I am giving the maximum expected values for calculation : -Database will be in mysql (Average service time of DB is 100-110ms in my computer[i5,4GB Ram]) -A request will transfer 150Kb data for each request on average. -Total user count : 1m -Active user count : 50k -Estimated request/sec for 1 active user : 0.06 -Total expected request/second to the server = ~5000 I am expecting this traffic between 20:00-1:00 everyday and then this values will decrease to 1/10 rest of the day. Is there any solution to this? [e.g increasing server capacity in a specific time period everyday to reduce cost]
