I have created a DataSet which is connected to an Access Database. This DataSet is linked to a report and I would like to apply a filter to only display information relevant to the logged in user. My question is, if I wanted to add a parameter to the filter in my DataSet, what is the correct syntax when entering parameters? Whatever I try, it seems to convert automatically to a string.

I want to add an attribute to the dataset declared below whose value is the value of one of the field in the row. So I want to add the id as shown below.
<root>
<Table id="GAS-405">

<orange>3.00</orange>
<pear>BGPR</pear>
<banana>GAS-405</banana>

This will me identify the node later in my application. Is this possible? Is this easier to do using XMLDocument?

I am using subsonic in asp.net forms C# and I have an instance where I need to loop through a recordset and for each one call the Database to get specific information from a view about that record.
in this instance it is a venue, loop through and for each venue I show there spend and there budget, but I am at a loss as to how I can say use a gridview, execute more code on each row and then add more columns to that row.
just as an update i have been playing with the idea of something like this:
DataSet ds = new DataSet();
ds.Tables.Add(LinqToDataTable(club.All().Where(x => x.level == 1)));
ds.Tables.Add(LinqToDataTable(ViewBudgetSpend.All().Where(x => x.periodfrom == curperiod)));
DataRelation relation = new DataRelation("budgets",ds.Tables[0].Columns["clubId"],ds.Tables[1].Columns["clubid"]);
ds.Relations.Add(relation);
still working this out though.

I have a CheckBoxList that is showing all A table C column.
SELECT DISTINCT C
FROM A
ORDER BY C
My A table has two columns.
B-->Primary Key
C--> Every C has a unique B.
I have an SQL like this for my Gridview Source;
Select <...............>
From <..................>
Where <.................>
AND A.B IN
(Select A.B
From A
Where A.C IN ALL CheckBoxList.SelectedItem.Value)
Something like that. My SQL syntax isn't very good. I hope you can tell what I want..
What I REALLY want is, when I click a button, Gridview should be populated according to the SQL , BUT filtered by what is selected in CheckBoxList.
Is there any way to add a parameter in the SQL IN clause?
Is there anything missing in IIS 6.0 that prevents me from (Insert into table) using MS-Access?
Explain: The application works fine under Visual Studio 2008 IDE the insert into table works fine with no error, Also I tested with hosting provider and works fine with no problem. but now I have published the same exact app in a dedicated server windows 2003 with
IIS 6.0 .NET framework 2.0 with latest service pack I gave IIS_WPG write/modify access to the folder where MS-Access database is located and database but at the time of insert an error pop-up. I need to install in the Server or settings in the IIS to recognize my MS-Access db is it some office runtime that I am missing. (BTW I am using OLEDB connection string in my C# )
Using System.Data.OleDb;
I can retrieve data off of it with no problem but when I try to insert is when it fails I thought the problem was Access Rights but I do not think is the case.
To Add new row to a dataset table, I am using code below. Before adding this how do I check if that row has already been added to the dataset?
Example:
Dim newCustomersRow As DataRow = DataSet1.Tables("Customers").NewRow()
newCustomersRow("CustomerID") = "ALFKI"
newCustomersRow("CompanyName") = "Alfreds Futterkiste"
DataSet1.Tables("Customers").Rows.Add(newCustomersRow)
Note: The table I am dealing with does not contain a primary key!
I need to create an interface for adding users to .Net Membership DB through an existing database. My Idea is to read each row from database from existing users table in a datatable and then iterate through each row and add it to new database. I cannot directly copy the rows from existing users table because the password stored in .Net Membership provider is in ir-reversible hash code and hashing is done through encryption algorithm present in front end code. My User count is huge (in millions).So what should i use to read the records, Dataset or datatable. Also tell what is the max number of rows it can hold.
