After reading about the differences between appSettings and applicationSettings in a web.config file, I'd rather use the applicationSettings section and benefit from the strongly typed settings. But with the appSettings section, you could previously have a separate section on a different file and simply reference it on the web.config us...
I am working on a WPF application for a vertical market. In a discussion today about how to build the data structure to support the selection of a dozen checkboxes and radio buttons, I thought about the possibility of serializing an object to XML and storing that in SQL Server, then deserializing it when the data needs to be displayed. ...
I am looking for a managed/unmanaged API that will allow me to find which objects reference another object and are potentially keeping it from being garbage collected. Such an API might look like this: var foo = new Foo(); var bar = new Bar(); bar.Foo = foo; var references = GC.GetReferencesTo(foo); // references is an array that con...

Hi guys Alex James talks about using stub entities to stub-out/fake relationships. The context in which this is discussed is for updates/inserts/deletes. I need to be able to do the same thing for a fetch. I want to be able to fetch some objects and have the foreign key reference objects be stub entities. How could I do this. Cheers ...
I've got a project where we'll need to generate a lot of fixed-length random codes (Read: Millions) from a set of characters (EG: 12 digit alpha-numeric or 9 digit alpha-numeric lower-case only without the l character). We're going to then store these codes in an MSSQL database (SQL Server 2008). The language we're using is C#. We also ...

Hi, the underlying database on a project has changed from sql 2005 to MySql 5.1 The code has loads of method similar to below.

Any help much appreciated. ...

I'm using an XmlReader.ReadInnerXML to read an XML document (as text) embedded within in an element of an outer XML document. This works fine except for the handling of tab characters in attributes of the inner XML. Example: <document> <interface> <scriptaction script="	one tab

I know that SortedDictionary is a binary search tree (and it can almost do what I need to do!) but I can't figure out how to do everything I need in the correct complexity. So here are the constraints (and the data structure which I know has it) Inserting and Deletion in O(log n) (SortedDictionary) Search in O(log n) (SortedDictionary...
Hi guys I'm faced with my first real practical usage of a many-to-many relationship and am having a little bit of trouble with the approach... I'm using ASP.Net MVC and have the following 2 entities: Activity <---> Program. Now I was wondering what people think of the approach and if there is a better way of doing this: When pull o...
It's possible to use the same strong name key for multiple related projects/assemblies. I'm interested to know whether there are any drawbacks to using this approach. SPecifically, can it lead to a lack of security? One area I'm thinking about this is in the use of the friend assemblies. ...
NOTE: I am not exactly sure how to title or tag this question, so if you have any ideas, PLEASE help! I'm currently envisioning a few possible projects that involve dynamically rendering something (whether it is a point, a line, text, or music notes on a staff, for hypothetical example), but, if I were to undertake these projects, I'm n...

I understand the String.Format since it a voids using the plus operator and make your code looker nicer. like for example string one = "bob"; string two = "jim"; string three = one + two; string three = String.Concat(one,two); ...

I'm currently looking at python because I really like the text parsing capabilities and the nltk library, but traditionally I am a .Net/C# programmer. I don't think IronPython is an integration point for me because I am using NLTK and presumably would need a port of that library to the CLR. I've looked a little at Python for .NET and w...

I've just created an upload page on an ASP.NET MVC application using the standard HTML for file uploading and it's working great using FireFox, IE8, Chrome, and Opera but it won't work for IE6 or IE7. Anybody know of any differences in IE6/7 that could be causing this to fail? ...
