using an ADO.NET dataset as a datasource for RS
Is it possible to use an ADO.NET dataset (as opposed to a Reporting Services dataset) as a datasource in Reporting Services? Thanks.
unless I misunderstood your question, I dont think they are different. what xactly is your question.***********************Dinakar NethiLife is short. Enjoy it.***********************
Yes, they are different. The datasource of a Reporting Services report is called (unfortunately) a "dataset," which is different than a dataset in ADO.NET. My question is as follows: let's say, for example, that I create an ADO.NET dataset in V...Cannot Access Strongly Typed Dataset columns directly using intellisense
Using VZW, I cannot access the columns directly using intellisense. I have to access the properties this way, which involves late binding. Category is the name of the dataset and the name of the data table.
Dim dsCat As Category = New CategoryDim taCat As CategoryTableAdapters.CategoryTableAdapter = New CategoryTableAdapters.CategoryTableAdapter
Dim rc As Int32Dim CatName As String
taCat.Fill(dsCat.Tables("Category"))rc = dsCat.Tables("Category").Rows.CountCatName = dsCat.Tables("Category").Rows(1)("categorydesc")
I see all direct access is private in the class vi...To use queryString or not to use QueryString
I am working on a project that requires loading and unloading user controls. To decide what to load or unload, I need to check two parameters. Problem is currently, I use Request.Querystring parameters to maintain those now and I was wondering if there is a better way to do that that even when the user clicks to refresh the page or tries to hack it, the code behaves in the manner it is supposed to, as in, based on user’s permission, the right action occurs and parameters passed, the right actions occur.

Once a user has logged into my application, they are directed to their admin page. On there, it will display if they have any new messages. I can assign the login name to the variable "yourname".
The messages are stored in the unimaginatively titled 'messages' table. The msgto and msgfrom fields are linked to the 'logins' table where the names are stored.
So far, I have created a tableadapter and have the query that will list the required fields for all the messages that are unread:

You can hide it.
Datacolumns have a ColumnMapping property that you can set to "invisible" if you don't want the column to appear in the file:
Column.ColumnMapping = MappingType.Hidden"look ma' no hands!"kpeguero
Excellent. It works fine. Thanks a lot.
I installed ODP.NEt 2.0 on top of my Oracle client 10g. I am developing a Data Access component. I am having the below problem.
I created the Data Layer class. The constructor of the data layer class initiates a new Oracle Connection. then I assign the Oracle Transaction obbject to the open connection. In my web page, I instantiate the DataLayer class and then call BeginTransaction method. At this point, my connection object is null. What am I missing?

Can anyone tell me how to access a dataset by column. For example how to loop the dataset by column and get the values of the rows.
You have to loop through your rows and to get the value for a column:

For Each row As DataRow in ds.Tables(0).Rows
' convert.tostring will change null values to string.empty
Dim myValue As String = Convert.ToString(row("MyColumnName"))
