• Cloud Database Service Latency/Performance

  - by Gcoop

  Hi All, I am running a heavy traffic site and our server is beginning to get to its limits, at the moment the entire LAMP stack is on one box (not ideal). I would like to move the database onto it's own box or onto a cloud service, but from my previous experience moving the database off the same box as the webserver increases the latency of reads quite dramatically slowing down the site. Is using a cloud service for this going to overcome this problem, because as far as I can tell its essentially the same situation (as moving it onto a separate box in my control)? In which case why is there so much popularity around cloud based database services at the moment? Are cloud based database services so quick that the latency of reads is so low that its almost like having it on the same box in the same datacentre?

• Automate open dialog in C#? (From COM OCX)

  - by JL

  I have a COM OCX control that I need to automate. It has a method called Open() this method is called without parameters, and always displays an open file dialog (standard one with windows). Is there a way for me to somehow get the file open dialog to open a file I specify , then close the dialog? I would also not like to use sendkeys or any other variants, because I require the solution to be reliable. So ideally would like to grab a handle on that window, and set the file name programatically, and then execute the open method programatically. Thanks in advance.

• Is it a good idea to "migrate business logic code into our domain model"?

  - by Bytecode Ninja

  I am reading Hibernate in Action and the author suggests to move business logic into our domain models (p. 306). For instance, in the example presented by the book, we have three entities named Item, Bid, and User and the author suggests to add a placeBid(User bidder, BigDecimal amount) method to the Item class. Considering that usually we have a distinct layer for business logic (e.g. Manager or Service classes in Spring) that among other things control transactions, etc. is this really a good advice? Isn't it better not to add business logic methods to our entities? Thanks in advance.

• the name 'controlname' does not exist in the current context

  - by zohair

  Hi, I have a web application that I'm working on(ASP.NET2.0 with C#)[Using VS2005]. Everything was working fine, and all of a sudden I get the error: Error 1 The name 'Label1' does not exist in the current context and 43 others of the sort for each time that I used a control in my codebehind of the page. This is only happening for 1 page. And it's as if the codebehind isn't recognizing the controls. Another interesting thing is that the intellisense isn't picking up any of the controls either.. I have tried to clean the solution file, delete the obj file, exclude the files from the project then re-add them, close VS and restart it, and even restart my computer, but none of these have worked. Please Help. Thank you

• Adding controls dynamically at design time vb.net

  - by chris

  I have been developing some custom smart tags. I am using a DesignerActionMethodItem which gets me to a fired method in code. When I try to hit the controls.Add the control is added but it seems the designer is unaware of it. It is never serialized and it goes away when the form is refreshed in the designer. Any help would be greatly appreciated. I am sort of stuck and google hasn't helped me. Please don't send me anything about smart tags that has nothing to do with adding controls dynamically at design time, I have already read so many looking for this.

• how to register a selectionProvider for the Viewer from a superclass

  - by Tom

  I have a View which extends a View provided by another plugin like this; public class View2 extends some.other.package.View1 { public void createPartControl(Composite parent) { super.createPartControl(parent); //I want to do this, but I can't because its private //getSite().setSelectionProvider(treeViewer); } } But I can't edit the super class, so I need to access the viewer from the Control. public class some.other.package.View1 extends ViewPart { private TreeViewer treeViewer; public void createPartControl(Composite parent) { treeViewer = new TreeViewer(parent, SWT.V_SCROLL); } } I tried using parent.getChildren(); to get a Tree object, but I can't see that it can be cooerced into an ISElectionProvider as required

• Silverlight DRY when animating multiple UserControls on main Navigation page.

  - by Tobias op den Brouw

  Hello all. Starting with Silverlight development. Yet to read a good Silverlight book: suggestions welcome. I have a main GUI screen where 7 user controls (menu items) 'swoop' into sight, all along their own path. I have the user controls nicely seperated and behaving well. Having multiple storyboards (1 each for each menuitem) with multiple keyframe animations (X,Y,height, width) in one .XAML is not sitting well with me. Repeating all those property values is hideous, neverthemind maintenance. I've tried to move values into the app.xaml and set animation durations with style keys, but having limited success. Can anyone suggest a nice way of making this cleaner? Refactor the storyboards out to their own control? Property values in resources? Dynamic building in codebehind? Referring me to a how-to site is fine as well. Tx!

• Windows Azure - Microsoft.IdentityModel not found

  - by rjovic

  I installed WIF runtime and SDK on my machine. I added Microsoft.IdentityModel.dll to my azure web application and locally everything is running great. I build simple web application which use Azure AppFabric Access control. I follow azure labs for that and as I told, local everything is great. When I published my web application to Azure, I'm getting following error : Unable to find assembly 'Microsoft.IdentityModel, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'. I get it after Appfabric Relaying part is going to return url, after sign in on identity provider. The weird thing is that I set Copy Local to TRUE, because that .dll is not part of Azure GAC. I tried to publish it again, but I received same error. I found few same problems on the internet but with no concrete solution. Does anybody here had something similar and probably have a working solution? Thank you in advance

• Protect files from svn commit.

  - by chrsk

  Hey, imagine a plain webapp with a log4j.properties which is under version control. I can't add it to svn:ignore because its a mandatory file. If i make custom changes for development and i don't want to commit them, i have to watch out for accidently commits. For one file it's easy to handle, with 3 or more files it becomes creepy. Is there a way to disable these files temporary from svn commit? So its easiert to commit? I'm working with svn and subclipse.

  - by Tony

  Hi, I was looking for the the trick to resolve that error (google, stackoverflow.com etc) and every nothing works. I need to dinamically create an .aspx file via the asp.net application. What I've done to try fix it: 1) In the folder's Properties - Security, I've added IUSR_TONY and also IIS_IUSRS and allow them the Full control to the folder. Just to check if that will help. Nope, it won't. 2) in the IIS Manager, I tried to change the Application's Pool Defaults Identity (based on that) I checked all options, with no success I don't know what to do more to fix it. Any ideas ?

• Adding dynamic controls to Silverlight application after WCF Service Asynchronous Callback

What am I missing? Thanks

• In Django, I want to insert a database record by sending myself an email?

  - by littlejim84

  Hello. I'm looking into a possible feature for my little to-do application... I like the idea that I can send an email to a particular email address, containing a to-do task I need to complete, and this will be read by my web application and be put in the database... So, when I come to log into my application, the to-do task I emailed will be there as a entry in the app. Is this possible? I have a slice with SliceHost (basically a dedicated server) so I have total control on what to install etc. I'm using Python/Django/MySQL for this. Any ideas on what steps to take to make this happen?

• create own svn repository hosting

  - by netmajor

  Hey, Since week I use ToirtoiseSVN and AnkhSVN and GoogleCode and sourceforge.net as my project hosting. For me it's frustrating to fill all this forms before create next project. So I start thinking about mu own repository hosting... Can I use simple file hosting etc. and install there software like use Google or SourceForge to have my own SVN Server ? My point is to have independent repository in internet without all this uselessly UI interface which give me Google and SF to administrate my version control. I don't want to take advantage of already exist hosting like GoogleCode etc - I want to be independent from them! ;) Or maybe it's other way to do my own repository hosting and FREE ;) Please don't tell me that I'm at mercy of commercial hosting... :/ p.s. If I wrote something wrong, sorry ;)

• What helpful tactics have you employed to keep your development team on-track?

  - by Ed Altorfer

  I realize that this is a subjective question, so I've marked it as a community wiki. I think that it is pretty specific to programming teams, though, so I've posted it here as opposed to somewhere else. I'm leading a small game development team (four people) as a side project. We are a disjoint team, with everyone in different places, but we do have some of the mainstays of an organized team. Source Control Continuous Integration Bug Tracking Document Workspace Regular Meetings Calendar / Schedule How do you keep your small, disjoint teams on-track? I tend to agree with Joel's opinion about when and how to micromanage and know that my team is motivated, but it can be easy to fall off-course when everyone isn't connected in a physical way and doesn't see what other people on the team are doing. Suggestions, feedback, or criticisms are welcome! Edit: I'm managing the team; I'm not looking for automated tools or anything to do my job for me, just ideas for approach or process that might help everyone feel more "connected" and involved.

• How to generate one large dependency map for the whole project that builds with makefiles?

  - by Stan

  I have a gigantic project that is built using makefiles. Running make at the root of the project takes over 20 minutes when no files have changed (i.e. just traversing the project and checking for updated files). I'd like to create a dependency map that will tell me which directories I need to run 'make' in based on the file(s) changed. I already have a list of updated files that I can get from my version control system, and I'd like to skip the 20 minutes of traversing and get straight to the locations that do need to be recompiled. The project has a mix of several languages and custom tools, so this would ideally be language-independent (i.e. it would only process all makefiles to generate dependencies). I'll settle for a C/C++-specific solution, too, as the majority of the project is in C++. The project is built on Linux.

Thanks in advance. Best Regards. Jose

• Silverlight 4 Assembly Sharing Problem

  - by jeffn825

  I have a WPF .NET 4.0 class library referencing a Silverlight 4 class library. The SL library compiles fine but when I compile the WPF class library, I get: Error 2 Unknown build error, 'Cannot resolve dependency to assembly 'System.Windows, Version=2.0.5.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e' because it has not been preloaded. When using the ReflectionOnly APIs, dependent assemblies must be pre-loaded or loaded on demand through the ReflectionOnlyAssemblyResolve event.' MyProj.Presentation.Wpf I figure the problem must be similar to the one mentioned here: http://markti.spaces.live.com/blog/cns!D92CF278F0F91957!273.entry but my WPF library doesn't contain any XAML that references a user control from my SL library. In fact, my SL library doesn't have any XAML in it at all. It does, however, have several shared DependencyObjects, such as an EventCommander (binding UI element events to Commands), and some DataTemplate helpers. Is there any way I can narrow down the problem here? And has anyone found a way of effectively referencing UI elements in a SL4 project from .NET 4.0? Thanks.

• Using svn with xampp for php projects

  - by idrish

  I have heard a lot about version control and would like to work on it. I read some tutorials about the same. However i am not quite sure how svn works with xampp. I have installed svn, Tortoise svn and made the necessary changes in xampp. For instance i copied the two required modules to c:/xampp/apache/modules and also made changes to the conf file in apache. Here are the changes made in c:/xampp/apache/conf/httpd.conf. # Configure Subversion repository <Location /svn> DAV svn SVNPath “C:\svn” AuthType Basic AuthName “Subversion repository” AuthUserFile “c:\svn_conf\passwd” Require valid-user </Location>t I created the repository at c:/svn and also created the password file. However when i visit http:/localhost/svn i get a 404 page not found error. Where am i going wrong. what am i missing.? Any pointers?? Thanks in advance.

• JQuery returns wrong value for IE Compatibility

  - by o-logn

  Hey , I'm using JQuery and there seems to be a problem when I run IE in compatibility mode (and generally any IE less than version 8). I'm trying to use attr("value") for a button control. In IE8, and other browsers, this works fine and the result of this code: alert($(this).attr("value")); is simply the value of set in the button attribute (e.g. Home, Settings, Help etc..) However, when this is run in IE compatibility view, I get the entire HTML as the output value: <SPAN class=ui-button-text>Home</SPAN> This causes my checks to fail. Is there a way to return just the Home section across all browsers? Thanks

• 'client_errors' warning in output from cron job that runs PHP on GoDaddy

  - by Kevin

  Hi. I have several cron jobs that I've set up on my GoDaddy hosting account through their control panel. The commands look like this: /web/cgi-bin/php5 "$HOME/html/myfolder/cron_do_stuff.php" The jobs runs as scheduled, and the scripts work perfectly, and the output from the scripts always gets sent to my email address. I would love a way to disable this (since the PHP script can send it's own emails if it's necessary). But my real question is about the output, which always contains this on the first line: /web/cgi-bin/php5: Symbol `client_errors' has different size in shared object, consider re-linking Looks like a server configuration error to me, and after talking with GoDaddy they said it's a benign warning and not to worry about it. I was just curious if anyone had ideas for fixing it.
