Having a database management class called DatabaseManager, I wanted to make a property for this DatabaseManager in a BaseForm. This way, every form inheriting from BaseForm would be able to use the same instance of the DatabaseManager.
Recently I ran into the Microsoft Skills Assessment page. After singing in with your passport, you can take all kinds of skills assessments for various Microsoft products, from Visual Studio 2005 to Windows Storage Server 2003.
BloggingAbout.NET was upgraded today! We are now CommunityServer 2.0 enabled. Because of this, I also changed the look and the description of my blog. Why not do everything at once 😉
Last night at eleven thirty, when I was taking a shower after playing volleyball for an hour and a half, I thought of a link between risk-based software development and….. a pop song*. Sometimes you think of stuff at the weirdest moments.
At our current project, we have an application which is deployed using No Touch Deployment. Because of some SEHException we got a few months back, we started our application in a separate thread using a launcher class which contains the Main() method for the application. Recently we added functionality to display HTML pages our application generates, so we added the ActiveX webbrowser (in AxSHDocVw.dll).
ScottGu blogged about IIS 7.0 on the MSDN .NET show. He and Bill Staples did an interview on IIS 7.0, which will ship with Windows Vista Beta 2. As Scott said: IIS 7.0 is a major, major update and improvement to the overall Microsoft web platform stack. See it. You can find it here.
Sometimes when you’re inside a method you would like to know which method called it. Or even which object. For instance when you write a TraceListener, it might be pretty cool to make the TraceListener smart enough to find out what object called him and from which method. The StackTrace object in .NET makes this pretty easy. Here’s a howto…
A few days ago we ran into the error in the subject of this post at my current project. Because it wasn’t easy finding any usefull hints pointing towards a solution, I’ll post ours here.
I’ve been thinking: would there be any interest for a bloggingabout .net meeting among the bloggers? We are all into .NET and most of us seem to enjoy a good discussion. Maybe we can organize a platform for those discussions in real life in stead of through posts and comments. It could be about anything, but has to have a predefined agenda to make sure the meeting has a goal.
The exception mentioned in the title of this post was the one I encountered when using an ASP.NET control I had written.
**How I encountered the exception:
** Because I develop several websites, there’s a lot of functionality I need more than once. A possible solution for this is to write a control gallery containing the functionality I needed. And putting them in a seperate assembly makes it easy to dstribute them freely in the near future ;). I made the assembly (containing an image gallery and a download gallery) and used it in a website I am developing together with a good friend of mine. There were no problems and life seemed good. Until the day came we published the website. After putting the website online, one of the pages was not rendering correctly, displaying the message “Unhandled Exception: System.Security.SecurityException: That assembly does not allow partially trusted callers”.
Yesterday we ran into a bug in the Visual Studio 2005 IDE. To be precise: in Intellisense when writing a web.sitemap file. The Intellisense tells you the attribute which indicates whether a site map provider filters site map nodes based on a user’s role is called securityTrimmingEnabled. But when you use this attribute and run the website, you receive an error stating there is an Unrecognized attribute ‘securityTrimmingEnabled’.
Wednesday and thursday I attended the first part of a BizTalk 2006 course at Class-A. Next week I’ll be finishing the course (tuesday and wednesday). I have to say that the trainer/coach who gives the course (Astrid Hackenberg) really knows what she’s talking about. At this point the 12 (?) people attending the course have not yet come up with a question she couldn’t answer.
