• Are you as productive in Javascript as you are in .Net or Java?

  - by bglenn

  I code primarily in javascript and in vb.net. I've found that if I can achieve the same thing in both javascript and vb.net that I feel far more productive and expressive using javascript for the task. I often find myself researching server-side javascript implementations to see if anything has gone mainstream so that I can code my back-end business logic and data access in javascript. Given all the advanced tooling and language features in .Net this preference seems somewhat paradoxical to me. I'm not suggesting one is better than the other (I've been a vb programmer since I started programming), I'm just wondering if my preference is entirely subjective or if anyone else shares it. So, does anyone else enjoy coding in javascript to the point where you prefer it to the .Net and Java environment, and if, so why?

• UIScrollView subviews not showing at first

  - by igul222

  I created a custom UIScrollView subclass that works a like a UITableView, keeping a collection of subviews and re-using them whenever the user scrolls. It's implemented like this: -(void)layoutSubviews { for(UIView *subview in [self subviews]) [subview removeFromSuperview]; // then re-add subviews after changing the frame and some attributes } This works fine with simple UIViews, but when I try to do it with a UIView that has a UILabel subview, the "base" view appears fine, but the UILabel doesn't show up at all. I can get the UILabel to show up by scrolling the entire UIView off screen and then bringing it back on. What could be causing this? So far, I've tried calling [myUIView setNeedsLayout], [myUIView setNeedsDisplay], and [myUIView layoutIfNeeded] from various places. None of them worked, and the last one crashed my app. I've also done the same thing to myUIScrollViewSubclass, with similar results.

• Very slow startup of ASP.NET applications

  - by Conrad

  I have an ASP.NET applications with quite small number of pages. The problem I see is that the startup time is quite slow. As far as I can tell, most of the time is spent in JIT. Pre-compiling the applications seem not very helpful in reducing the #methods JIT as reported thru PerfMon. Does anybody know what I can do to reduce the startup time further? Is it true that there is no way to pre-jit an ASP.NET application using NGEN?

• Active directory select and display with asp.net (oledb) (error code: DB_E_ERRORSINCOMMAND(0x80040E1

  - by Phil

  I am trying to make a page which displays some user information returned from active directory. Here is my code so far: Dim oConnection As OleDbConnection Dim oCmd As OleDbCommand Dim strADOQuery As String Dim oleReader As OleDbDataReader oConnection = New OleDbConnection() oCmd = New OleDbCommand() oConnection.ConnectionString = "Provider=ADsDSOObject;" oConnection.Open() oCmd.Connection = oConnection strADOQuery = "select distinguishedName, cn, givenname, sn, mail, middleName, displayName, description, telephonenumber, physicalDeliveryOfficeName, employeeID from 'LDAP://dc=foo,dc=ac,dc=uk' WHERE objectCategory='Person' AND objectClass='user' AND sAMAccountName='" & Uname & "'""" oCmd.CommandText = strADOQuery oCmd.CommandTimeout = 600 oCmd.ExecuteReader() While oleReader.Read ADDN = r("distinguishedName") ADCommonName = r("cn") ADFirstName = r("givenname") ADLastName = r("sn") ADEmail = r("mail") ADFirstandLast = r("displayName") ADDescription = r("description") ADTelephone = r("telephonenumber") ADOffice = r("physicalDeliveryOfficeName") ADStaffnum = r("employeeID") End While oConnection.Close() oleReader.Close() I'm finding it hard to see exactly what is wrong with the code. The error message presented is vague: 'ADsDSOObject' failed with no error message available, result code: DB_E_ERRORSINCOMMAND(0x80040E14). Any assistance would be greatly appreciated Thanks.

• Fastest way to write large STL vector to file using STL

  - by ljubak

  I have a large vector (10^9 elements) of chars, and I was wondering what is the fastest way to write such vector to a file. So far I've been using next code: vector<char> vs; // ... Fill vector with data ofstream outfile("nanocube.txt", ios::out | ios::binary); ostream_iterator<char> oi(outfile, '\0'); copy(vs.begin(), vs.end(), oi); For this code it takes approximately two minutes to write all data to file. The actual question is: "Can I make it faster using STL and how"?

• Which Devices Support Javascript Geolocation via navigator.geolocation ?

  - by Maciek

  The iPhone supports geolocation in mobile Safari via the following call: navigator.geolocation.getCurrentPosition( function(pos){ var lat = pos.coords.latitude; var long = pos.coords.longitude; }, function(){ /* Handler if location could not be found */ } ); I'd like to build a good list of devices that have one of the following: support this feature out of the box, or support this feature with an upgrade, or support geolocation with equivalent fidelity of data with some other snippet of Javascript. I'm only familiar with my own device, so this is my list so far: Out of the box: iPhone 3GS Supported, but only with an update iPhone 3G iPhone 2G (?) PC or Mac computer with Firefox 3.5 Supported with some other snippet ? What is the level of support in Blackberry, Android phones, etc?

• Printing PDFs Server-side using Acrobat Reader from ASP.NET

  - by Chris Roberts

  Hi, I have been presented with a problem which requires me to print PDF files from a server as part of an ASP.NET web service. The problem is further complicated by the fact that the PDF files I have to print can ONLY be printed using Adobe Reader (they were created using Adobe LiveCycle and have some strange protection in them). This piece of code seems to do the trick in the Visual Studio development web server, but doesn't do anything when the site's running in IIS. I'm assuming this is probably some sort of permissions issue!? I know this is a FAR from ideal thing to be trying to do, but I haven't really got much choice! Any ideas would be greatly appreciated! Dim starter As ProcessStartInfo Dim Prc As Process ' Pass File Path And Arguments starter = New ProcessStartInfo("c:\program files\...\AcroRd32.exe", "/t ""test.pdf"" ""Printer""") starter.CreateNoWindow = True starter.RedirectStandardOutput = True starter.UseShellExecute = False ' Start Adobe Process Prc = New Process() Prc.StartInfo = starter Prc.Start()

• Reputable TabletPC vendors

  - by SnOrfus

  I'm developing software for tablet pcs and so far I've used some lenovo's (x41), some toshiba's (portege m200) and some gateways (M275). Granted: the machines we've gotten have predominantly been refurbs, but they're failing 80-90% of the time. Part of the reason that they're failing is users inevitably dropping them, so I'm looking at potentially some rugged tablet pcs. The problem that I'm running into is that Current tablet pcs are high spec (much higher than I'm looking for at least) The rugged tablet manufacturer space seems to be filled with lots of small companies that I don't trust yet. I'm looking for tablet PCs (keyboard or no) that can support: XP tpc (optional win 7) single core 1.5-2ghz 1gb ram wifi optional gsm optional gps very optional vehicle docking solutions The budget I've got is tight (but slightly flexible - So are there any reputable tablet pc vendors out there that can do this.

• Hide ticks at Min and Max in WPF Slider

  - by gehho

  Hi, I want to display a Slider ranging from 0.5 to 1.5 with only one tick mark at 1.0 to mark the center and default value. I have defined a Slider as follows: <Slider Minimum="0.5" Maximum="1.5" IsMoveToPointEnabled="True" IsSnapToTickEnabled="False" Orientation="Horizontal" Ticks="1.0" TickPlacement="BottomRight" Value="{Binding SomeProperty, Mode=TwoWay}"/> However, besides a tick mark at 0.0 this Slider also shows tick marks at 0.5 and 1.5, i.e. the Minimum and Maximum values. Is there a way to hide these min/max tick marks?! I checked all properties and tried changing some of them, but did not have success so far. Thanks, gehho.

• What is the "standard" JQuery treeview that most people use? It seems the most popular plugin isn't

  - by Pete Alvin

  I've chosen JQuery as my JavaScript library but now I'm a bit frustrated by the JQuery plugin site... the site kinda sucks... the plugin area isn't designed very well and I can only find a few treeviews. The one with the most votes (link text) isn't supported anymore. Can someone please point me to an industrial strength treeview? Desired Features: 1. stable 2. async / ajax would be nice 3. drag and drop nodes would be nice I've been delighted so far with JQueryUI--nice design. But, how come it doesn't come with a standard tree view? Pete

• Base URL in ASP.net Master Pages with virtual Directories

  - by Ian

  Hi All, I have an ASP.net master page. In this master, I have all my css and javascript files defined. I also have a few images and a few buttons and hyperlinks. All the urls are all declared as relative ie "/scripts/ian.js" Everything works fine if this site is the root website, but I need it to work in a virtual directory. My problem is when I place this website in a virtual directory under a root site, all my links are pointing to the root site. so my links point to www.root.com/scripts/ian.js but it should be pointing to www.root.com/virtualDir/scripts/ian.js I thought the Base Href tag in the header would help, but so far it does not seem to be helping in anyway. All the links are still pointing to the root website when i hover over them. Any suggestions or ideas are welcome. Thanks

• Integrating my website with BlogEngine.Net

  - by Kabeer

  Hello. I am developing a site (ASP.Net based) that, besides other features enables the users to blog as well. I am thinking of integrating BlogEngine.Net to my portal. From whatever little I have analyzed, integrating at presentation layer will be far more challenging in comparison to doing so at business layer. That means (I guess) I will have to use the BlogEngine.Core.dll in my application. I am looking for some sort of approval from the community, complimented with suggested do's and dont's. BTW, I find the business layer a bit intimidating (complex) as I want some basic & necessary features only.

• Which coding style is more common?

  - by Babiker

  In no way shape or form am i advertising/promoting my programming style, but as far as 'multiple variable declarations' are concerned, which case is more acceptable professionally and commonly: case 1: private $databaseURL = "localhost" ; private $databaseUName = "root" ; private $databasePWord = "" ; private $databaseName = "AirAlliance"; case 2: private $databaseURL = "localhost"; private $databaseUName = "root"; private $databasePWord = ""; private $databaseName = "AirAlliance"; The reason i like case 1 is because i can skim though it and see that all is correct way faster than case 2. Also i can visually get familiar with variable names witch makes it faster to work with them l latter on the program.

• Is it possible to get Cufon to work on a button?

  - by Tom Harvey

  So right now I'm bashing my head - at the moment we use an element for a button to give it our own custom font, fine - this works, but as we're using Cufon on the rest of the site, we're wondering if it's possible to get Cufon working on a button. So far I've changed the button to an and using standard css styles on an 'input' or 'input[type="submit"]' element work fine - but I've tried both of these in cufon to no avail. This is a button - so as Cufon generates images, this should work, but maybe I'm doing it wrong - can anyone help?

• Wrapping/warping a CALayer/UIView (or OpenGL) in 3D (iPhone)

  - by jbrennan

  I've got a UIView (and thus a CALayer) which I'm trying to warp or bend slightly in 3D space. That is, imagine my UIView is a flat label which I want to partially wrap around a beer bottle (not 360 degrees around, just on one "side"). I figured this would be possible by applying a transform to the view's layer, but as far as I can tell, this transform is limited to rotation, scale and translation of the layer uniformly. I could be wrong here, as my linear algebra is foggy at this point, to say the least. How can I achieve this?

• DB structure for Twitter home/Facebook wall?

  - by mathon12

  Basically a live feed of all your friends' recent posts. In a stupid sort of approach I think I'd start by building a query like: SELECT * FROM tblposts WHERE userid=friend_id_1OR userid=friend_id_2...... and so on Where friend_id_% is the userid of a friend from your friends list. But this must be a very inefficient way of doing it, right? Is there any faster way of doing this in MySQL? Maybe some clever DB schema? (I know FB uses Hadoob but I'm not experienced enough to go that far :( )

• Display Image over map layer in GeoServer

  - by iririr

  Hi I am newbie when it comes to GeoServer and trying to figure out if there is an easy way to display images on top of map layer. A background: In my application, based on a search criteria, some polygons are drawn on the map. Each polygon has a corresponding image (in TIFF format) that is stored somewhere. I want to load the image on top of the map when the user zooms in to a certain zoom level. I know this can be done using openLayers but since my images are in TIFF format, (openLayers is not able to render TIFF images as far as i know) i have to convert them to .PNG first which would be very slow considering the number of images i have. Hence I was wondering whether it would be possible to create a image layer that would retrieve an image of a certain polygon at a certain zoom level. If so, could anyone point me to an example or give me an idea on whether this is possible. I am using spring 2.5, tomcat 5, java 1.6 and geoserver 2.0 Thanks.

• VBScript & Access MDB - 800A0E7A - "Provider cannot be found. It may not be properly installed"

  - by Perma

  Hey gang, I've having a problem with a VBScript connecting to an access MDB Database. My platform is Vista64, but the majority of resources out there are for ASP/IIS7. Quite simply, I can't get it to connect. I'm getting the following error: 800A0E7A - "Provider cannot be found. It may not be properly installed" My code is: Set conn = CreateObject("ADODB.Connection") strConnect = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\database.MDB" conn.Open strConnect So far I have ran %WINDIR%\System32\odbcad32.exe to try to configure the Driver in 32bit mode, but it hasn't done the trick. Any suggestions would be greatly appreciated

• How do I unescape HTML entities in a string in Python 3.1?

  - by Sho Minamimoto

  I have looked all around and only found solutions for python 2.6 and earlier, NOTHING on how to do this in python 3.X. (I only have access to Win7 box.) I HAVE to be able to do this in 3.1 and preferably without external libraries. Currently, I have httplib2 installed and access to command-prompt curl (that's how I'm getting the source code for pages). Unfortunately, curl does not decode html entities, as far as I know, I couldn't find a command to decode it in the documentation. YES, I've tried to get Beautiful Soup to work, MANY TIMES without success in 3.X. If you could provide EXPLICIT instructions on how to get it to work in python 3 in MS Windows environment, I would be very grateful. So, to be clear, I need to turn strings like this: Suzy &amp; John into a string like this: "Suzy & John".

• Resolving IEnumerable<T> with Unity

  - by Mark Seemann

  Can Unity automatically resolve IEnumerable<T>? Let's say I have a class with this constructor: public CoalescingParserSelector(IEnumerable<IParserBuilder> parserBuilders) and I configure individual IParserBuilder instances in the container: container.RegisterType<IParserSelector, CoalescingParserSelector>(); container.RegisterType<IParserBuilder, HelpParserBuilder>(); container.RegisterType<IParserBuilder, SomeOtherParserBuilder>(); can I make this work without having to implement a custom implementation of IEnumerable<IParserBuilder>? var selector = container.Resolve<IParserSelector>(); So far I haven't been able to express this in any simple way, but I'm still ramping up on Unity so I may have missed something.

• Obtaining IP addresses in Bittorrent

  - by Legend

  I am trying to get a list of IP addresses serving or downloading a file. What I did was to contact a tracker like openbittorrent.com to get the following (as part of the scrape file): B%00%00%0C%5F%B1%B1l%CAGa%84S%CB%B0%9BG%84%3BE:0:1 Now, the long string in the beginning is the info hash. As a next step, I did this: http://tracker.sometracker.com/announce?info_hash=B%00%00%0C%5F%B1%B1l%CAGa%84S%CB%B0%9BG%84%3BE It gave me back the following. So far so good. The message contained this: d8:completei0e10:downloadedi0e10:incompletei2e8:intervali1931e12:min intervali965e5:peers12:U????????^@^@e Can someone tell me what should I be doing after this to get the IP addresses currently serving the file or downloading it?

• Dynamic mod_rewrite or how to plan a dynamic website

  - by Sophia Gavish

  Hi, I'm trying to make a clean url for a blog on a dynamic website, but I think that the problem is that I don't know how to plan the website schema. I read about how to use mod_rewrite and all I found is how to make "http://www.website.com/?category&date&post-title" to "http://www.website.com/category/date/post-title". that's works o.k for me. The problem is that If my url looks like "http://www.website.com/blog/?id=34" this method won't work as far as I got it. So, I have two questions: 1. Is there a way to use mod_rewrite (maybe read from a txt file) to read the post title of my blog and rewrite my url by date and post-title? 2. Should I rewrite my website to query the data from one index file in the homepage and use mod_rewrite to write the nice url? should I query also the date and the title of the post instead just the post ID?
