Ok, I ran into a problem, MS out of some odd wisdom didn't do as you would think with the defaultvalue of a data column. you would think it so simple right? In a database such as SQL server you can set the default value to a function, I can do this with a datacolumn too such as. column1.defaultvalue = system.guid.newguid Though this has an issue, if you use this in a grid you will see as you add new rows that the darn guid is the same. It's calling the newguid only once when setting up the table and it's holding that value static for the rest of the life of the datatable\datacolumn. This goes against common knowlege in how MS does things in other area's, such as the before mentioned SQL server using NewID() will get you a new ID each time. Keep in mind that even other funtions like Now() (which returns current date time) won't work, the defaultvalue will always be the same datetime. So I don't have a solution for the default, I have a different solution. Custom datatable and custom datacolumn classes. You will see in my custom column style that there is a new property called (autogenerateguid)if set to true then it will then set each new row with the correct new guid. Though this is all code based, it works for what I need it to do. It also features the use of an un-documented function and class. NewRowFromBuilder Function System.Data.DataRowBuilder Class I've seen other post's that show to use the rowchanging or positionchanged events in order to do the same thing, this example gets to the source of the newrow creation. What would be better is that if you assign a function that MS would call that function each time instead of this lame static method.

A markov chain is a sequence of random variables in which the future variable is determined by the present variable but is independent of the way in which the present state arose from its predecessors. The code is a simple example of a markov chain that generates somewhat random text output from a given text input.

I had a problem when downloading mp3's. With no cd burner or network i couldn't get my mp3's to a friends house. So i made an mp3 splitter. A normal 4.0 mb song could fit on three disks. but it this splitter can support up to 30 mb's. I doubt any song is longer than that

This program draws a reddish pyramid with a fountain in the middle which contains wavy water, and sprays out blue particles (well it was SUPPOSED to look like water, lol). There is also a red globe in the center of all of this floating in midair for no reason at all. This project was a great learning experiance for me, but keep in mind it isn't all original coding. I got the base code from Dustin Davis' project at http://www.planetsourcecode.com/xq/ASP/txtCodeId.1080/lngWId.3/qx/vb/scripts/ShowCode.htm and I learned much of the stuff that I added to it at nehe.gamedev.net.

This system will teach you how to: Populate the DataSet programmatically instead of with a wizard, Using stored procedures, fill a DataSet with complete tables from the database and then create relationships between the tables, Write the business logic to dynamically build a SQL statement to fulfill the user's criteria given on the Search Screen, Fill a DataSet with the results of the SQL query, Verify in the Output window that the data in the DataSet correctly reflects the user criteria entered on the Search Screen, Simple and complex data binding, Building the Add/View/Edit Products and Suppliers Screens, Using the ErrorProvider control to validate user input, Using DataViews to filter and sort data in the DataSet, Using the DataReader to return a single record, Updating a DataSet based on user input, Allowing the user to add, edit, and delete data in the DataSet on the Add/Edit/View, Products and Suppliers screens, Creating a second dataset that contains all changes made by invoking the GetChanges method, Checking for errors in the changed dataset by checking the HasErrors property, Saving the changes in the DataSet back to the database using Stored Procedures, Accepting or rejecting the changes made based on whether the updates were successful and Handling any errors that occur. Using Northwind SQL database
