• Make VS 2008 Auto Deploy SQL Server CE 3.5 When Debugging on Windows Mobile 5.0 Device

  - by INTPnerd

  How do you make VS 2008 automatically install SQL Server CE 3.5 when debugging (F5) a CF app on a windows Mobile 5.0 device? VS used to do this automatically, but now it stopped and I don't know why. I have changed the structure of my solution and the projects, but it is still using SQL Server CE 3.5. It used to also install the Query Analyzer as well which was useful. I frequently uninstall all the programs on the device or do hard reboots so installing this manually is what I am trying to avoid.

• Project Euler 79: what am I missing?

  - by Evert

  Hi Guys, I'm not interested in the answer, but I need to be pointed in the right direction Here's problem 79 I first try to analyze the file myself. I've noticed that the number 7 only ever appears as the first digit. This immediately implies that all the numbers containing 7 never overlaps with under numbers (on the left side). Since the questions in project euler always have 1 answer, I believe I'm misunderstanding the question. Do I not have to use all numbers? If I do have to use all numbers, there's many different possible numbers. Where am I going wrong?

• Simplest possible table entry editing / addition / deletion web toolkit (for use with php)

  - by Dave

  Hi, i'm building a website in php and i have tables presented that i need to allow the user to: 1. add new entry (only one at a time, which should appear as a new modal overlay) 2. delete multiple selected entries from 3. edit an existing entry (only one at one time, in a view similar to 1.) 4. re-arrange entries up and down. One by one is fine. Multiple / Grouping rearrangements are not not needed what jquery / js / anything toolkit would be the SIMPLEST to work with? (of course, i should be able to work with it in php). I did try hacking away at: http://www.ericmmartin.com/projects/simplemodal/ but had a terrible time trying to get it to work on editing some existing data (had problem passing data to it).

• Able to ping but cannot browse after several hours running of my python program

  - by Shane

  It's a GUI program I wrote in python checking website/server status running on my XP SP3, multi threads are used to check different site/server. After several hours running, the program starts to get urlopen error timed out all the time, and this always happens right after a POST request from a server(not a certain one, might be A or B or C), and it's also not the first POST request causing the problem, normally after several hours running and it happens to make a POST request at an unknown moment, all you get from then on is urlopen error timed out. I'm still able to ping but cannot browse any site, once the program closed everything's fine. It's definitely the program causing this problem, well I just don't know how to debug/check what the problem is, also don't know if it's from OS side or my program wasting too many resources/connections(are you still able to ping when too many connections used?), would anybody please help me out?

• How use applicationSettings in the new web.config configuration in VS2010?

  - by citronas

  I'm used to use web deployment projects. Currently I am developing a new web application with VS2010 and want to try to get along with the new web.config principle and deployment issues. How can I replace a simple setting like <applicationSettings> <NAMESPACE> <setting name="Testenvironment" serializeAs="String"> <value>True</value> </setting> </NAMESPACE> </applicationSettings> I want to have this setting to be set to True in Debug, and false in Release. How must the entries in the Web.Debug.config and Web.Release.Config look like? And by the way: Is there some documentation about the new web.config issue? Can't seem to google for the correct keywords.

• WCF - Compact Framework - Pull data from mobile client

  - by jagse

  Hello guys, I want to communicate xml serialized objects from the server to the client and the other way arround. Now it is (probably) easy to invoke methods from a mobile client (compact framework) using WCF, but is there a way so that the server can invoke methods on the client side or some other way to pull data from the client? I know that callback contracts are not available in the compact framework as you can see here: http://blogs.msdn.com/andrewarnottms/archive/2007/09/13/calling-wcf-services-from-netcf-3-5-using-compact-wcf-and-netcfsvcutil-exe.aspx Originally I thought of socket programming and of developing this by myself, then someone here mentioned WCF. But it seems like WCF only would work in a non mobile environment as I need callbacks. Anyone can help me with this? Is it possible to develop a two way communication with a desktop server and multiple mobile clients using WCF, or will I have to do socket programming? Thanks for any advice or any kind of help!

• Recommended Visual Studio config for referencing an assembly created with ILMerge

  - by Daniel Schaffer

  I have a solution in Visual Studio with 5 projects. They are: Foo.Core: Core functionality Foo.Api: Generated code built on top of core Foo.Web: Web-specific extensions Foo.Web.Mvc: MVC-specific extensions Newtonsoft.Json: 3rd party library I want to use ILMerge to merge Foo.Core, Foo.Api and Newtonsoft.Json into a single assembly, called Foo. That's the easy part. The problem I'm running into is that Foo.Web and Foo.Web.Mvc both need to reference all three of the merged assemblies. If I reference the original assemblies, they will have invalid references after I do the ILMerge. If I reference the ILMerged assembly, I have to reference a debug assembly and then change it before I package everything up, which doesn't seem ideal. I've tried creating a project called Foo, which references the 3 merged assemblies and replaces its own output with the ILmerged assembly, but that doesn't seem to work at all. Is there a reliable way to do this?

• Why is VB so popular? [closed]

  - by aaaidan

  To me, Visual Basic seems clumsy, ugly, error-prone, and difficult to read. I'll let others explain why. While VB.net has clearly been a huge leap forward for the language in terms of features, I still don't understand why anyone would choose to code in VB over, say, C#. However, I still see (what seems to be) the vast majority of commercial web apps from "MS shops" are built in VB. I could stand corrected on this, but VB still seems more popular than it deserves. Can anyone help answer any (or all) of these questions: Am I missing something with VB? Is it easier to learn, or "friendlier" than C#? Are there features I don't know about? Why is VB/VB.net so frequently used today, especially in web projects?

• NSDateFormatter incorrect date on simulator, correct date on device

  - by Rudiger

  Hi, Im building a calendar and to find out the first day of the month I do [formatter setDateFormat:@"e"]; int startDay = [[formatter stringFromDate:newDate] intValue]; On the device this works correctly and the 1st of the month is on the correct day. But on the simulator it is the day after. Although it doesn't overly matter about the simulator it is kind of driving me crazy thinking I've done something wrong. I tried to set the locale of the formatter but no difference, nor i think should it. Can anyone shed some light on this? On a side note is there a better way to build a calendar than this?

• Can Core Data be used on Linux?

  - by glenc

  This might be a stupid question, but I was wondering whether or not you can use the Core Data libraries on Linux at all? I'm planning how to build the server side of an iPhone app that I'm working on, and have found that you can use PyObjC to get access to Core Data in a Python environment, e.g. use Core Data in a TurboGears web application. At this point I'm thinking that you would have to run the web server on Mac OSX, because I can't find any evidence on the internet that you can access the Objective-C libraries on Linux. I've always written webapps on Linux but will obviously make the jump to an OSX server if it allows me to use the same datastore implementation on the iPhone and the server, the only job remaining being the Core Data <- Web Services XML translation that has to happen on the wire.

• How Do I Detect A WordPress Admin Panel in my Plugin?

  - by Volomike

  I've got two events in my plugin. One is run for the front-end. The other is run for the admin panel. Both call the same function in one particular situation, and this echoes stuff to the screen. How do I make it such that the function is smart, calls something in WordPress, and detects whether it's being loaded in the front-end versus the admin panel? I don't want it to echo stuff to the screen on the front-end, but do want it to do so on the admin panel. Right now, it's echoing on both, which is not what I want. Background For the front end (the side of the site that the visitor sees), I'm intercepting the 'wp' event and checking for: ( is_single() || is_page() || is_home() || is_archive() || is_category() || is_tag()) For the admin panel, I'm intercepting the 'admin_menu' event. I tried intercepting the is_*() stuff above, but it seems to somehow answer TRUE or something, not giving me a difference between front-end and admin panel.

• Is there any JavaScript Library to intelligently truncate strings?

  - by j0ker

  I need to truncate strings in a side menu to make the fit into a div without a linebreak. The divs have a fixed width. I'm looking for a library to do that for me. If a string is too long to fit into the div, it should be truncated like: <div>This string is too long</div> == <div>This string is...ong</div> As you can see, the string is not only truncated by an ellipsis but the last three letters are also visible. This is meant to increase readability. The truncation should not care about spaces. Does anyone know of a library that includes such functionality? We're mainly using jQuery throughout the project. Thanks in advance!

• prevent bots to query my database several times

  - by Alain

  Hi all, I'm building an application that is a kind of registry. Think about the dictionary: you lookup for a word and it return something if the word is founded. Now, that registry is going to store valuable informations about companies, and some could be tempted to get the complete listing. My application use EJB 3.0 that replies to WS. So I was thinking about permits a maximum of 10 query per IP address per day. Storing the IP address and a counter on a table that would be empty by a script every night. Is it a good idea/practice to do so? If yes, how can I get the IP address on the EJB side? Is there a better way to prevent something to get all the data from my database? I've also though about CAPTCHA but I think it's a pain for the user, and sometime, they are difficult to read even for real human. Hope it's all clear since I'm not english... Thanks Alain

• Behavior of a pipe after a fork()

  - by Steve Melvin

  When reading about pipes in Advanced Programming in the UNIX Environment, I noticed that after a fork that the parent can close() the read end of a pipe and it doesn't close the read end for the child. When a process forks, does its file descriptors get retained? What I mean by this is that before the fork the pipe read file descriptor had a retain count of 1, and after the fork 2. When the parent closed its read side the fd went to 1 and is kept open for the child. Is this essentially what is happening? Does this behavior also occur for regular file descriptors?

• When making a branch in TortoiseSVN, what do "head", "working copy", and "specific" revisions mean?

  - by Asad Butt

  A new user of Tortoise SVN, working over source control. I have a Visual Studio solution which consists of 5 webAppliation projects. I need to take one out and work over it in a branch. When I try to branch it, It is asking me of one of these options head revision in repository specific revision in repository working copy revision Problem 1: What exactly are these ? I am confused with "head revision" and "working copy", as they appear same to me. EDIT: Problem 2: Why cant we branch from Repository GUI itself, (would be head revision) ? Problem 3: Can you list the steps, needed to branch from a directory !

• Grafting Scala 2.8 into a Netbeans NBAndroid Project...What steps am I missing?

  - by Michael Kohout

  Hi All; Due to Apple's recent T+C hijinks, I've become interested in developing for Android. Anyways, I'm trying to get a mixed-language Android 2.1 project going in Netbeans 6.8 (with the NBAndroid 0.10 plugin). The two languages being Java and Scala(2.8 head build). To give you a basic idea of what the app does right now, it's just a simple "Hello World" app. To get this to build, I've modified the projects's build.xml file: -- -injars ${scala-library}(!META-INF/MANIFEST.MF,!library.properties) -outjars "${build.classes.dir}/classes.min.jar" -libraryjars "${file.reference.android.jar}" -dontwarn -dontoptimize -dontobfuscate -keep public class * extends android.app.Activity -keep public class scala.xml.include.sax.Main** I've gotten the project so that it'll build, but it errors on startup in my Android Emulator(inside the emulator Android tells me my application has stopped unexpectedly). So my questions are: Does anyone see what I may be doing wrong? And is there any way to get access to the logs that the emulator must create? thanks Mike Kohout

• wrap text around image IE

  - by Tillebeck

  Hi I have done a bit of searching for a solution to wrap text around an image and came across the JQSlickWrap. http://stackoverflow.com/questions/2457266/jquery-plugin-to-wrap-text-around-images-support-ie6 But it is not working in IE. Is there another way to wrap text around an image? Or is that just not possible for IE yet?... Great wrap example in firefox but not so great in IE: http://jwf.us/projects/jQSlickWrap/example1.html There is this manuel way to create div's but in my case that is a no-go since it is multible images uploaded by a webmaster.

• Integrating Tomcat7 and Eclipse Helios on Snow Leopard

  - by ktm5124

  I am trying to write a "Hello World" web application using Tomcat and Eclipse, in order to familiarize myself with building Tomcat projects. So far I've gleaned from Google searches that I need to install Eclipse Web Tools Platform (WTP) to go ahead with it. But when I go to Help-Install New Software I can't find any software update site that is hosting WTP. My default "Available Software Sites" are Helios, Mylyn for Eclipse Helios, and the Eclipse Project Updates. Do I need to add a new software update site to install WTP? If so, what is the URL? If not, where can I find WTP? Thanks in advance.

• What happens after a packet is captured?

  - by Rayne

  Hi all, I've been reading about what happens after packets are captured by NICs, and the more I read, the more I'm confused. Firstly, I've read that traditionally, after a packet is captured by the NIC, it gets copied to a block of memory in the kernel space, then to the user space for whatever application that then works on the packet data. Then I read about DMA, where the NIC directly copies the packet into memory, bypassing the CPU. So is the NIC - kernel memory - User space memory flow still valid? Also, do most NIC (e.g. Myricom) use DMA to improve packet capture rates? Secondly, does RSS (Receive Side Scaling) work similarly in both Windows and Linux systems? I can only find detailed explanations on how RSS works in MSDN articles, where they talk about how RSS (and MSI-X) works on Windows Server 2008. But the same concept of RSS and MSI-X should still apply for linux systems, right? Thank you. Regards, Rayne

• Redirecting a HTTP rqueust and response code/headers

  - by Bill Zimmerman

  Hi, I have a loosely coupled web app (one part uses PHP, the other uses WGSI). The WSGI/python framework shares the authentication with the PHP app, meaning that generally, the user should Log in via the PHP interface Now the user can access any of the WSGI pages [this part works if the user has logged in] What I want to do though, is if a user tries to access a WSGI page while not logged in (maybe from a previous bookmark), I would like to redirect him to the login page, and after logging in redirect him back to the orignal URL. I'm not very experienced with server-side programming, so here are my questions. How should I redirect the user back to the PHP login page? What should the HTTP status code be? Do I need to set any extra header information? What is a good way/best practice method to pass the original URL to the login page, and then after logging have it redirect the user back. Thank you!

• ASP.NET AJAX UpdatePanel problem

  - by Velika

  I'll try and be concise: 1) I have a dropdownlist with Autopostback set to TRUE 2) I have an UpdatePanel that contains a Label. 3) When the downdownlist selection is changed, I want to update the label. Problem: Focus is lost on the dropdownlist, forcing the user to click on the dropdownlist to reset focus back to the control. My "solution": In the DropDownList_SelectionChanged event, set focus back to the drop down list: dropdownlist1.focus() Problem: While this works great in IE, Firefox and Chrome change the scroll position such that the control which was assigned focus is positioned at the bottom on the visible portion of the browser window. This is often a very disorientating side effect. How can this be avoided so it works in FF as it does in IE?

• Are All Dynamic Languages Typo-friendly?

  - by yar

  With Java on one side and Ruby/Groovy on the other, I know that in the second camp I'm free to make typos which will not get caught until run-time. Is this true of all dynamically-typed languages? Edit: I've been asked to elaborate on the type of typo. In Ruby and in Groovy, you can assign to a variable with an accidental name that is never read. You can call methods that don't exist (obviously your tests should catch this, it's been said). You can refer to classes that don't exist, etc. etc. Basically any valid syntax, even with typographical errors, is valid in both Ruby and Groovy.
