I'm trying to get the results of a stored proc (with no input parameters)
into a datagridview. I'm able to get the results into a messagebox but i'm
nor sure how to get them into a DataGridView

Using cn As New SqlConnection(strConn)
Try
cn.Open()
Catch ex As Exception
MessageBox.Show("Connect Attempt Failed")
MessageBox.Show(ex.Message.ToString)
End Try

Dim cmd As New SqlCommand("sp_TestBilly", cn)
cmd.CommandType = CommandType.StoredProcedure

Dim rdr As SqlDataReader
rdr = cmd.ExecuteReader(CommandBehavior.CloseConnection)

'Do While rdr.Read()
' MessageBox.Show(rdr(0) & " " & rdr(1) & " " & rdr(2) & " "
& rdr(3) & " " & rdr(4) & " " & rdr(5) & " " & rdr(6), "sp_BillyTest")
'Loop
'rdr.Close()




datagridview1.DataSource=***here's where I can't get the code
right****



cn.Close()
End Using
End Sub

myDataGridView.DataSource = dt
cn.Close()
End Using

You can't use a DataReader; it reads the data one row at a time, it doesn't
keep the whole set of data in memory. You have to use a DataSet, DataTable,
List(Of T), Collection, Arraylist, or something like that.

Add
Dim dt as new DataTable
dt.Load rdr

before binding dt to the DataSource.

This is explained in detail in my book...

As usual, Bill is right. Sigh. I don't use DataReaders very much. I guess I
should buy his book and read it. ;-)

Thanks that was perfect. I'll have to take a look at your book.

Is there someway to put the data into excel. I know how how to open an
instance of excel but can't seem to figure out how to past the data without
cycling through each cell.


Dim oXL As Excel.Application
Dim oWB As Excel.Workbook
Dim oSheet As Excel.Worksheet

oXL = CreateObject("excel.application")

oWB = oXL.Workbooks.Add
oSheet = oWB.ActiveSheet


oSheet.Cells(11, 1) = myDataGridView.DataSource **this doesn't work**

oXL.Visible = True
oXL.UserControl = True

You can do that with ADO.Net, I believe, without automating Excel. I
haven't done it personally, but if you google this newsgroup and
microsoft.public.dotnet.languages.vb, you'll find it's been asked and
answered multiple times.
