I used the select disctinct statement with 2 fields from my sql database table. Here is my code.
myCommand = New SqlCommand("SELECT DISTINCT Author FROM tblBook UNION SELECT DISTINCT BookCode FROM tblBook",myConnection)
myAdapter = New SqlDataAdapter(myCommand)
myAdapter.Fill(myDataSet, "tblBook")
cboAuthor.DataSource = myDataSet.Tables(0)
cboAuthor.DisplayMember = "Author"
cboAuthor.DisplayValue = "BookCode"
and it generates error : cannot bind to the new member. Parameter name:value.

I have a query that can be summarised in SQL as follows;
Select
S.StockCode
From
StockToCheck As S
[Code]....
Where the S var is a list of strings. This gives the error 'S' is not declared and points to the S in the function call / join (GetPOSStock). So it does not seem possible to do this in Linq, can anyone confirm?

I have the following problem: I select a customer from a dropdownlist and then the gridview should load all items of all orders of that customer. I have the following query:
Dim allorders = From ord In db.Orders
Where ord.CustomerID = Convert.ToInt32(CustomerDropDownList.SelectedValue)

Dim orderitems = From oi In db.OrderItems
Where oi.OrderNumber = (From From ord In db.Orders

But this does not work. I just started using LINQ.

I have a form showing a datagrid that is filled with info from an Access database table. The table only has 3 fields: two of them are string type and the third one is boolean. The first String type field is also the primary key (this field is called "clave"). This datagrid is supposed to let the user select one of the rows and then click on a button to delete that row.

I'm getting the error: The parameterized query(@CustomerID, @ProductCode, @DateOpened) expects the parameter @ProductCode, which was not supplied.For one thing, my INSERT query has five parameters, not just the three listed in the error notice.
Another thing, I supplied @ProductCode in the AddWithValue statement.
Another thing is that I don't get the error when I change:
InsertCommand.Parameters.AddWithValue("@DateOpened", Date.Today.Date)

I am connecting to an Access database and using a parameter query with the LIKE operator to return all rows that match query. The string to search for is taken from a Textbox
sql =
"Select * FROM Allview WHERE Info Like" &
"*" &
CStr(TextBox1.Text) &
"*"
The query does not return any data in vb, but when run from access with same string, there is data returned.The connection to the database is done correctly, as I am able to return data with various other queries.
Partial code :
Dim

I am trying to run a query an Access db from VB. The general query which I want to run is
SELECT * FROM Patient WHERE Patient.PatientID = ?
or SELECT * FROM Patient WHERE Patient.PatientLname = ?
I tried using an input box which captured the user input and pass that variable to the query, but that failed. Then I read about writing a function and using that, however, I keep getting an error which says Function not defined, but when stepping through the code, it seems to work. Here is my function: [Code]

When I try to use the following line of code:
cboSite.DataBindings.Add("Text", _dtSite.Select("Site <> 'ALL'"), "Site")
I get the following exception:
EXCEPTION : Cannot bind to the property or column Site on the DataSource.{10}Parameter name: dataMember
details I am connecting to an Access database and using .net 3.5 and writing the code in VB. In this database I have a table named Sites with a column named Site and when I try to use the line of code above I get the exception noted. I was under the impression that I could explicitly name the column that I need to use in my control (combo box).

Seems most of the examples I find are c#, so in some cases I'm left scratching my head... to make a long story short, I'm simply trying to output the selectList of items to a drop-down within my view:
My ViewModel:
Imports System.Web
Imports Whitebox.UI
Namespace ViewModels
[Code]...
All I'm trying to do now is simply output my "SelectList" within a HTML.DROPDOWNLIST() in my view.When doing a step through, my list items are showing within my "Return view(viewmodel)" watch, but I'm stuck with performing the output.

End If
