• Is there a way to reduce the verbosity of using String.Format(...., p1, p2, p3)?

  - by Edward Tanguay

  I often use String.Format() because it makes the building of strings more readable and manageable. Is there anyway to reduce its syntactical verbosity, e.g. with an extension method, etc.? Logger.LogEntry(String.Format("text '{0}' registered", pair.IdCode)); public static void LogEntry(string message) { ... } e.g. I would like to use all my and other methods that receive a string the way I use Console.Write(), e.g.: Logger.LogEntry("text '{0}' registered", pair.IdCode);

• [VS2008] - Run Add-in from PrebuildEvent

  - by JBL

  I'm writing an VS 2008 add-in to synchronize Setup project Version with startup project assembly version. It works fine. But I was wondering if it was possible to call add-in from the Prebuild Event of my setup project. It works fine by command line window, but I didn't find any syntax to make it work in prebuildEvent. Is Someone has an idea ? Thanks

• Is this a hole in dynamic binding in C# 4?

  - by Galilyou

  I've seen a very interesting post on Fabio Maulo's blog. Here's the code and the bug if you don't want to jump to the url. I defined a new generic class like so: public class TableStorageInitializer<TTableEntity> where TTableEntity : class, new() { public void Initialize() { InitializeInstance(new TTableEntity()); } public void InitializeInstance(dynamic entity) { entity.PartitionKey = Guid.NewGuid().ToString(); entity.RowKey = Guid.NewGuid().ToString(); } } Note that InitializeInstance accepts one parameter, which is of type dynamic. Now to test this class, I defined another class that is nested inside my main Program class like so: class Program { static void Main(string[] args) { TableStorageInitializer<MyClass> x = new TableStorageInitializer<MyClass>(); x.Initialize(); } private class MyClass { public string PartitionKey { get; set; } public string RowKey { get; set; } public DateTime Timestamp { get; set; } } } Note: the inner class "MyClass" is declared private. Now if i run this code I get a "Microsoft.CSharp.RuntimeBinder.RuntimeBinderException" on the line "entity.PartitionKey = Guide.NewGuid().ToString()". The interesting part, though is that the message of the exception says "Object doesn't contain a definition for PartitionKey". Also note that if you changed the modifier of the nested class to public, the code will execute with no problems. So what do you guys think is really happening under the hood? Please refer to any documentation -of course if this is documented anywhere- that you may find?

• Is there a work around for setAppCacheEnabled on WebView for an Android 2.1 application causing the

  - by Kevin

  We have an HTML 5.0 web application that we ported to Android. It's our intention to run this in a Native Wrapper. Our application uses the ApplicationCache to run offline. This works find when running under the browser. While being hosted in a WebView within a native application, after the last file is downloaded and stored in the ApplicationCache from the manifest the application is terminated and does a core dump. This appears to be a documented bug. http://code.google.com/p/android/issues/detail?id=7939 Has anyone doing anything similar found a work around for this issue?

• Working with iPhone OS 3.2 only classes

  - by user324881

  How would you write a universal app that uses classes introduced in iPhone OS 3.2, such as UIPopoverController and UISplitViewController? On Jeff LaMarche's blog about this, Ole provides a method for instantiating these objects; you would instantiate a UIPopoverController like so: [NSClassFromString(@"UIPopoverController") alloc]. This is fine for instantiating these classes in code but what about protocols and their methods? My iPad app uses a UISplitViewController and has a class that needs to conform to the UISplitViewControllerDelegate and UIPopoverControllerDelegate. How would you declare this? And how would you work with a method such as the following? - (void)splitViewController:(UISplitViewController *)svc willHideViewController:(UIViewController *)aViewController withBarButtonItem:(UIBarButtonItem *)barButtonItem forPopoverController:(UIPopoverController *)pc where the method call requires UISplitViewController to be passed in?

• JSF managed bean question

  - by Nitesh Panchal

  Hello, I have one page which uses <ui:insert> called master.xhtml which uses one managedbean named MasterBean.java and its of viewScoped. It calls webservice and has all useful data which will be useful in master.xhtml as well as page which is built using master.xhtml (which uses <ui:include>). When i visit data.xhtml (which uses template as master.xhtml) and which uses managed bean as DataBean.java which is also of view scoped, how do i use MasterBean? If i directly use #{Masterbean.property}, won't it create a new instance again? or will it use the bean which is already in view scope? Also how do i use MasterBean in DataBean in such a way that existing MasterBean's instance is used in DataBean. I don't want new instance of MasterBean in DataBean. Thanks in advance. If i am not clear please let me know.

• How to prevent shortcuts from firing when form is not active

  - by Erick Sasse

  I open forms inside tabs of a page control. These forms may contain actions with shortcuts. And I want these shortcuts to be fired only when the tab that contain this form is active. I tried to override form's IsShortCut but it's not called. Form's OnShortCut is not called either. I would like to avoid putting code on each action to check this. I'm using Delphi 2010.

• Distribute terrabyte files to the public from web server

  - by MarkJ

  Hi We need to set up a website which makes two or three large files publicly available - the files will be 1 or 2 terrabytes each. Although they will be public, in practise I expect only a relatively small number of scientists will want to download them. What is the best way to allow this? I've had a quick talk to a web-hosting provider (rackspace) and they suggested a hybrid solution. An entry-level managed server (we predict fairly low traffic for the website, but we do need to install some custom CGI software). Some cloud storage which hooks into Limelight Networks. This would host the large files, for download by FTP. It sounded OK to me but I know relatively little about server administration. Does it make sense? Thanks in advance, Mark

• A-2-Z web hosting on Amazon AWS

  - by JDelage

  All, I am studying web dvp, and one of my classes is project-based. We have to build a functional site that demonstrate our understanding of: HTML, CSS, Javascript, php, MySQL, And potentially Ajax or some other web component. For the project, we can use a local server using WampServer and basically build the site entirely on our laptop. If I have time, I would like to create a real site, and I thought it would be a good way to familiarize myself with Amazon's AWS services. So if I purchase a domain name, can I rely on AWS to host the site from A-to-Z? I understand I can use AWS to host content, the database, and do the background computations, if needed. What else do I need and what are the parts that AWS cannot help me with? Second, is there good documentation for a beginner to navigate AWS and learn how to use it (either on Amazon, or some 3rd party sites, or even a good book, as long as is up to date). The ideal documentation would be a tutorial on creating a web site from a-to-z on AWS, as detailed as possible. As you can guess, I have limited understanding of the IT issues. I have 0 Linux or sysadmin experience, but this is a good opportunity to change that. I hope you can help me. Thank you, JDelage PS: Please keep the answers AWS-specific. At this point, I am only interested in alternative services to the extent that they plug a hole in Amazon's offering.

• excel pivot tables stopped working after upgrade to office 2007

  - by some random guy

  An excel document with several pivot and lookup tables that previously worked under office xp and 2003 stopped working after an upgrade to office 2007 (linked stuff doesn't update). I originally assumed there's something disabled in 2007 that I need to turn back on, but after having opened it in excel 2007 it no longer works in previous versions either. Any idea what I'm missing/what excel 2007 did?
