Passing parameter for Stored Procedure to Data Adapter/Data Set

2.Data Adapters, Data Sets, Data TableMappings, and XML

Here's what I'm trying to do:

1. Create a data adapter with Select and Insert commands.

2. Use DataTableMappings to map XML tags into columns in a 
data base table.

3. Create a dataset

3. Read in a schema using dataset.ReadXmLSchema

4. Read in an xml file that contains the data using 
dataset.Read XML

5. Add 3 new columns to the dataset. (These columns have 
already been mapped in step 2).

6. Put data in the 3 new columns.

7. Modify some data in the other columns using xpath 
queries to find the nodes that need changing.

8. Use datadapter.update(dataset, tablename)

Everything seems to work fine until step 8. I get all the 
data, the extra columns get added, and the data in other 
columns gets modified. When I execute step 8 I get:

Run-time exception thrown : 
System.InvalidOperationException - Cannot add or remove 
columns from the table once the DataSet is mapped to a 
loaded XML document.

Any ideas about how I can either fix this or do it another 
way.

TIA,
Candi

3.problem with data adapter and data set while inserting and retrieving data

i am using a data adapter and a dataset for filling and retrieving data
into .mdb database.
following is the code.....

for the form load event
  Dim dc(0) As DataColumn
        Try
            If OleDbConnection1.State = ConnectionState.Closed Then
                OleDbConnection1.Open()
            Else
                MsgBox("connection can not be established")
            End If
            DA.Fill(DataSet11, "Table1")
            cmd = New OleDbCommandBuilder(DA)
            dc(0) = DataSet11.Tables("Table1").Columns("EmpID")
            DataSet11.Tables("Table1").PrimaryKey = dc
        Catch ex As Exception
            MsgBox(ex.Message)
        End Try
        Delete.Enabled = False
    End Sub

for  inserting values into the DB

Private Sub Insert_Click(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles Insert.Click
        Dim dr As DataRow
        dr = DataSet11.Tables("Table1").NewRow
        dr.Item(0) = Val(TB1.Text)
        dr.Item(1) = TB2.Text
        dr.Item(2) = TB3.Text
        dr.Item(3) = Val(TB4.Text)
        dr.Item(4) = TB5.Text
        DataSet11.Tables("Table1").Rows.Add(dr)
        DA.Update(DataSet11, "Table1")
        MsgBox("data is saved")
        rno = 0
        call filldata()

filldata function consists of the following

 With DataSet11.Tables("Table1").Rows(rno)
         TB1.Text = Trim(.Item(0))
         TB2.Text = Trim(.Item(1))
         TB3.Text = Trim(.Item(2))
         TB5.Text = Trim(.Item(4))
         End With

the error it gives is " there is no row at
0........system.nullreference...........i checked the connection and
its working fine and also the database is getting accessed........the
error is occuring at the line " With
DataSet11.Tables("Table1").Rows(rno) "

4.Table Adapter Configuration Wizard replaces data table name with stored procedure's

Hi

When using Table Adapter Configuration Wizard if 'Use SQL Statements' is 
selected as Command Type, the data table's name in dataset is retained and 
only its data adapter's select statements are replaced. If however 'Create 
new stored procedures' is selected as Command Type, the data table name in 
replaced by the name of the newly created select stored procedure. Problem 
with this is that the data table's name needs to be put back manually.

Is there a way to keep the data table name the same and just stored 
procedures are assigned to the data table's data adapter?

Thanks

5.Need practical advice on using single stored procedure to process data adapter commands

Im trying to minimize the number of stored procedures and was
wondering if there is any downside to using a single stored procedure
to handle the select,insert,update, and delete commands for a data
adapter.

I create the sql dataadapter using system tables to generate the
parameters and add an additional parameter to denote the type of
process.

Would appreciate any experienced criticisms.....thanks
