Overview To make it short : LinQ to SQL only works with SQL Server but it’s working great. It’s simple, supports all LinQ operations and optimizes the generated SQL queries. LinQ to Entities on ADO.Net works with lots of database but it doesn’t behave like LinQ to SQL and doesn’t support some key LinQ features. Now the long story : For the last project I’ve been working on, we wanted to use LinQ and still be able to switch to one database to an other (MSSQL to MySQL for instance).
I recently took the time to take a look inside the Microsoft.Sharepoint.dll using reflector. I’m not sure I have the right to do that. And I’m pretty sure I don’t have the right to publish any code extracted from it, so I won’t show any. Using SPSite(s) and SPWeb(s) If you do some timing on the SPWeb creation call (SPSite.OpenWeb), you will find out that it’s freaking fast (less then 1 ms on my server).
Yes, I have tested MonoVS with the version 0.2.2641 (on both client and server). I installed OpenSuse 11.1 and added the MonoVS software repository, and everything worked ! I would have prefer to get it from SVN in order to use it in my Debian hosts but the mono development team seems to have removed it from their SVN repository. So, the Mono Remote Debugger for Visual Studio works, but there still some bugs.
I’ve talked about this before. When you create versions of webparts, you have two main solutions to update existing webparts : Create a binding redirect within the web.config file. Update each and every webpart instance of the collection site (or just the site). The first one is really the best solution : It’s simple and very fast. But, it applies to the whole Web Application. Sometimes, the client might want to only update the site collection or even the website.
When I saw that Google Latitude now enables you to access your data by a JSON feed, I decided to make it communicate with a little GPS tracking project of mine. I’m really found of all these ways we now have to make anything communicate with anything. You can build interfaces from any system to any other system really easily. This code enables you to automatically get your GPS position (or the position of a friend) from your JSON Latitude feed.
I talked some time ago about a library I made to take advantage of the kernel network events. I now release it and explain how to use it. It can help people to do some little network software without knowing where to start from. I built it for network servers made to communicate with remotely connected embedded chips. I wanted to be able to always stay in touch with a huge number of chips without any real cost.
I tested it in VS2010. Which is beautiful by the way, I like the WPF rendering. And I’m happy they didn’t disable the possibility to generate .Net 2.0 assemblies. I wanted to test the new historical debugger functionnality, which enable you to see the state of variable in the past time, but I didn’t take the Team System Edition (and I’m too lazy to download it again). named and optionnal arguments
If you’re faced with that error, you should know that it doesn’t mean anything except you have a problem. Lots of people have written posts about it, but most of their explanations are wrong. It just means that sharepoint didn’t like what you did somewhere in your masterpage, your page, your webpart, your user control or anything else. For me, it was because I used the SPWeb.GetListFromUrl method to test if the user actually had access to a list.
As I already told before, I love the Mono project. It enables to run the powerful Microsoft .Net Framework on UNIX/Linux/BSD systems. I recently wanted to test a very cool feature of ASP.Net on a mono server. So I did a little apt-get install lighttpd mono-fastcgi-server2 -y The feature I wanted to try was a web scripting method ( with the [WebMethod] attribute) exporting some JSON directly from your method return value.
When you begin with Sharepoint like it did (and still do), you will ask your self: “What object should I dispose ?”. It’s quite important because Sharepoint leaks approximately 1 Mb per “IDisposable object not disposed”. If it’s a menu, it could quickly make you loose 10 Mb per loaded page. The best and complete answer is in the MSDN. But it’s a pretty long answer. The short answer is :
