• .NET Development .LoadFrom Dependency

  Hello All, I've built a light weight plugin kind of feature using Reflection. I use LoadFrom to load plugins from several sub folders under the main application folder. Each of the plugin sub folders may contain one or more assemblies. I understand that assemblies that are loaded using LoadFrom uses the concept of a load context, and when assembly references need to be resolved, the path where the load from assembly exists is also probed. I have a problem that I have not been able to fix - Assembly References indeed get resolved and the sub folders get probed as well. But not for all the references. I have found that assemblies that the plugin references and those that are built by me (my private assemblies - strong named) get ...Show All

• .NET Development How can i release resources used by Bitmap

  Hi, can anyone help me about releasing resources used by bitmap i have some usercontrols in my app and they displays an image from mediafiles.

• SQL Server Most effecient way to get "previous row" values?

  Wow, this board has gotten really busy lately - maybe 2007 is the year that a lot more people start using SSIS :) Anyway my question is this: If I have an ordered set of data in the data flow and I want to add a column, lets just say "previousID" that basically has the ID value of a column from the row immediately before it - what is the most effecient way of doing that I've done much more complicated things with running averages, mean, etc by creating an asynchronous script transformation, pushing the data into a datatable in memory and looping through row by row using variables etc to do the calcs... but I just have this feeling that there is a "lighter, faster, easier" way for just getting previous row's value (with ...Show All

• Visual C# Dissappearing class through web service

  Hello all I'm having a weird experiece with a C# web service I'm building in that a class keeps going missing. My webservice deals with creating and managing sales orders and items that relate to sales orders. When running locally through VS2005's ASP.NET server both classes are present and accounted for but when I publish the webservice one of the classes is no longer available. A cut down version of my webservice class code looks like: Hello again I have figured out the problem. The class was not being displayed because I was not referencing it correctly.

• Visual Studio 2008 (Pre-release) sending 30 MB from a WCF server to many clients

  I need to create a solution for this scenario: A lot of clients all over the world (winforms) should play media files that a server sends them. The server has a playlist of media files for each of those client. Whenever a playlist is changed on the server the client should 'know' about it and download the media files. the size of the files could be around 30 MB. Should I use WCF to send the files to the client or should I use FTP instead What is the diference between WCF and FTP in terms of speed , security and scalability i am not FTP expert,i am thinking mixing WCF and FTP may be better choice for perf reasons you can use WCF to send alerts messages from service ->client once client knows abou ...Show All

• .NET Development Interface as generic type parameters

  What happens, when I define a generic type with an interface (e.g. List<IComparer> behind the scenes Does the CLR treats the list as a reference type list or as a value type list Meaning, does it create a new specialized type for that list, or does it use an already existing reference type for the list If the later is true, then it means that this list could store both value types and reference types, but it will do a lot of boxing/unboxing operations when accessing value types won't it Thanks. A List<> needs to store it elements somewhere. Only the heap qualifies. Value types stored in the List<> are therefore automatically boxed. ...Show All
