Differences Between ADO.NET DataSet And ADO Record Set?
Apr 20, 2010
What's your opinion of the following job interview question?In the requirement it never mentions about to have classic ASP experience.
But the question is "What are the differences between ADO.NET DataSet and ADO Record Set?".
I have two datasets, one is populated from a SQL Database on my server, the other is populated from an XML file passed from the client server.Both datasets are identical in structure (and potentially the same in data as well)hat I need to be able to do is as follows:-Compare Dataset1 against Dataset2 and record which rows are missing from Dataset2 (based on 2 primary fields)Compare Dataset2 against Dataset1 and record which rows are missing from Dataset1 (based on 2 primary fields)Compare Dataset1 against Dataset2 and record any rows which are different ((based on 2 primary fields always being the same and 3 fields being potentially different)
I select few columns from table A in dataset. Example "EMP_ID","Name","Address","Phone_Number". I want to save data in this dataset into some other table B.
I want to save data from dataset into table B. But i want to have following functionality
1. Before saving a record from dataset to table B if that record if previously present in table B, if yes then check if any value are different, if yes then update that record with the record from dataset, if all the values are same then leave the records as is.
2. If the record is not present in table B then insert it new records in table B from dataset.
Is there any efficient way to implement in .NET C#.
to get limited records using this method? i.e. by filling dataset using adapter and providing min and max record limit?I wish to do custom pagination using this method.
using vb.net 2005 and crystal reports. in the vb.net code I am querying the database, processing the results and then binding to the crystal report.
What I need to do now in the code is this: I need to create a new page to display the results so that there is one page for each row in the dataset that I'm binding to the report.
i wants to display the related informations of each record of dataset. That mean, dataset having rows for A,B,C and etc..
Then i wants to display the information in same Gridview of each record(A,B,C). i wrote the below my coding, it dispaly info of the last row of dataset only. pls correct the coding.

I am using asp.net and the .net framework 2.0. I may be able to upgrade the servers to 3.5 if the solution is compelling enough. Here is the problem.I have two pieces of xml.I'll refer to piece number 1 as the template and piece number 2 as the actual.Here's a basic example:template:
What is the difference between validateRequest (which validates form and querystring values) and also enableeventvalidation, which works on post/call backs? In specific, what confuses me is that validateRequest can only be possible by a postback as this is how form values etc will be picked up?

having consistency problems between the web browsers and im pretty sure its gotta be something in my code.Website displays correctly in chrome yet in IE my content placeholder has alligned itself to the left and the errors message shows in the bottom left corner.
http://www.drpcni.com/test/deafult is an example.
It happens in all of my pages so im thinking it could be something that is placed in my master page. Below is the code from my master page (I know its probably awful use of code but im new and learning)
I want to calculate the current time differences between US/Central timezone and British Summer Time. I mean, currently these both timezones have daylight savings going on, so they have a 6 hours time difference. But after Sunday October 31 2010, daylight savings will be off for British summer time, at which moment there will be a 5 hours time differences between these two timezones.
Is there any way I can calculate these varying time differences?
In my project I work with Entity Framework (LINQ to ENTITY). I only have ADO.NET Entity Data Model and a DAL (Data Access Layer). I also get the data due a WCFClientService. I have a gridview that needed to be exported in Excel.
FlexCel is a tool for generating Excel files based on a template. The only thing I see in demo's is that they work with DataSets.
Is there a way to convert the data in my gridview to a virtual DataSet?
I've written the following method to get the data:
