I'm implementing 'check' constraints that simply call a CLR function for each constrained column. Each CLR function is one or two lines of code that attempts to construct an instance of the user-defined C# data class associated with that column. For example, a "Score" class has a constructor which throws a meaningful error message when...
I have an application that creates database tables on the fly. I'd like to create an interface to CRUD this data. But because the tables are created as the application runs, I can’t create the Linq to SQL classes by dragging them onto the designer. However, I do know in my code what the tables I want to edit are. Can anyone tell me if ...
I've written a little script that collects my external IP address every time I open a new terminal window and appends it, at well as the current time, to a text file. I'm looking for ideas on a way to visualize when/how often my IP address changes. I bounce between home and campus and could separate them using the script, but it would be...
Hi all, On UNIX, I have to produce numeric results out of previous data by means of various command-line utilities. These utilities read the starting data (in general, but not only, from csv files), perform computations, and write the data (again, in general, but not only, to csv files). Of course, I don't want to run the risk to have ...

This means that whenever I get ready to commit some business data to a database, I have to pass all of the business properties into the data method's parameter. For example: Public Function Commit(foo as o...

Say I have a file based data structure such as a B+ Tree. My understanding is that the data is expected to be stored on disk, but the index is usually loaded in memory. What if you have such a large file that even its index doesn't fit into memory? How is that typically handled? Secondly, since the index is a tree, not a linear set of...

I work for a community college in North Carolina. Our most central repository of data is a software system called Datatel, aka Colleague (why it has two names, I don't know). In our case the underlying data store is IBM Unidata. I develop with .net technologies. Does anyone have any idea about consuming data from Datatel/Colleague in a...

Functionality similar to a databound combo box, but in radio button format. Silly me, I thought this would be built in, but no. How do you do it? ...
I want to set a FourCC value in C++, i.e. an unsigned 4 byte integer. I suppose the obvious way is a #define, e.g. #define FOURCC(a,b,c,d) ( (uint32) (((d)<<24) | ((c)<<16) | ((b)<<8) | (a)) ) and then: uint32 id( FOURCC('b','l','a','h') ); What is the most elegant way you can think to do this? ...
Hi, I am recently working on some long and obscure codes written by some other smart guys. I'm thinking of generating the Data Flow Diagrams and the Flowcharts to facilitate my work. Is there any kinds of software that can do this job automatically? P.S. Most of the codes are in C and Fortran. ...
