View 4 RepliesI am trying to figure something out. I have an application in which I am adding the ability to consume a feed. I have no problem with the feed itself, but my problem is how can I mark certain items as 'read'? The only thing I can thing of is to read the feed into a database. In this database, I add a column for 'read' which I update when the user has read the article. Then each time I retrieve the feed, I compare the feed to the database and only load new items into the database.

How would that look in a database? and then how would you load the tree. I can load everything up to the grandchild, but as soon as I load the great grandchild I start having issues. So I am thinking it is the way they are in the database.

I'm trying to load a large CSV file into a Microsoft SQL Server Compact 3.5 database. I've tried using the following: Using MyReader As New Microsoft.VisualBasic.FileIO.TextFieldParser("filename.txt") MyReader.TextFieldType = FileIO.FieldType.Delimited MyReader.SetDelimiters(",")Then splitting the data with MyReader.ReadFields() etc, before using this data to add rows to a dataset in a database table in my project. However, my CSV files are very large, at above 9.5 million rows, and this takes forever, if the computer doesn't crash also. Does anyone have a better idea for what to do? I would like the CSV file to be loaded into the database table, to enable me to sort it, and undertake some querys and maths. The CSV data structure is:2,193,761.40000000000012,43,1510.22,8,1929.60000000000012,22,2564.52,22,2791.70000000000032,19,2971.6000000000004

View 8 RepliesI have a program with two forms, one that handles the applications controls, and the other with the functions that open a file (csv), open a database, and query the database. The controls on the first form are a list box, three labels (to display parsed csv information), and three buttons (clear database, load database from csv, and load listbox).
The clear database and load database buttons (events) seem to function correctly.On the other hand, the load list box event doesn't function 100% the way I'd want. [And, I can't test the selected index event yet]
The code for the load list box event is:

b.openConnection("weather.mdb") 'open database connection
db.query("SELECT * FROM stations") 'query database
Do While db.moreRecords

View 1 RepliesI create a new Windows Forms Application project in VB.NET without changing any of the settings or labels. Then I click on "Add Data Source" and go through the steps in my programming book. Except that Visual Studio is crashing with a message stating that VB encountered a problem...checking for causes...restarting VB.
Sometimes I get to click the "Debug and Run" button before this happens; other times, it occurs before I move all the labels in form from the data source; and still other times, it happens when I click the "Stop Debugging" button.
I have tried removing VB and reinstalling it, but this still is not helping. (If it matters, I'm getting my copy of VB from [URL]
