• .NET Development Data files?

  Is it possible to use datafiles in C# if so how i have a project to do in C# and Data files would help bunches. Well, the next logical step would be to use a binary file, through a BinaryReader and BinaryWriter (see the doc). These will allow you to read and write arrays of bytes from a file, and also to move to a specified position in the file using the Seek method. You will need to determine a fixe ...Show All

• Visual Studio 2008 (Pre-release) Why the name "DLinq"?

  Any reason for why it's called "DLinq"   It seems that calling it "RLinq", with the R for Relational, or "SLinq", with the S for SQL, would make more sense. This is true.. However, as you allude, it need not remain so. I think it wouldn't take much to have a pluggable DataContext provider which would contain the logic for determining what to send to the server.  I'm guessing the translation logic is i ...Show All

  I have a graph that is properly displaying data for each year and then by each subsidy. However, when it displays data for the current year (2006), for the subsidies with no current data, it carries over the data (the sum of the total) from the previous year for the data points. There is no bar on the graph which is correct, however the data point from the previous year does display. For subsidies that do have data for the current year, this ...Show All
