I have a DataGridView that I populate from an Excel file. The problem is I want to add the Excel file to my resources (if possible) then populate the DataGridView from there.

I use this now:

VB

Try
    Dim MyConnection As System.Data.OleDb.OleDbConnection
    'Dim DtSet As System.Data.DataSet
    Dim MyCommand As System.Data.OleDb.OleDbDataAdapter
    MyConnection = New System.Data.OleDb.OleDbConnection _
            ("provider=Microsoft.Jet.OLEDB.4.0;Data Source='C:\coded\Vehicle\Vehicles.xls';Extended Properties=Excel 8.0;")
    MyCommand = New System.Data.OleDb.OleDbDataAdapter _
                ("select * from [Sheet1$]", MyConnection)
    MyCommand.TableMappings.Add("Table", "TestTable")
    'DtSet = New System.Data.DataSet
    MyCommand.Fill(DataSet1)
    DataGridView1.DataSource = DataSet1.Tables(0)
    MyConnection.Close()
Catch ex As Exception
    MsgBox(ex.ToString)
End Try

Do not put the Excel file in your resources. You're just going to have to write it to a folder and to get at the data anyway, so what's the point?

If you want the data in your Resources, you'll have to move the data to another format, such as an XML file, in to put the data in Resources and avoid writing it back to a file.

Why? The .NET XML classes are capable of reading data from a Stream object, whereas Excel and the data providers that work with it cannot. Those providers do not know anything about a .NET Stream object, limiting them to using actual files on disk.

I added an xml file to my project but when it tries to open it say it cannot find the file

Dim dsPubs As New DataSet()
dsPubs.ReadXml("Vehicles.xml")
Me.DataGridView1.DataSource = dsPubs.Tables(0)

Me.ComboBox1.DataSource = dsPubs.Tables(0)
Me.ComboBox1.DisplayMember = "MAKE_MODEL_DESCRIPTION"

Me.ComboBox2.DataSource = dsPubs.Tables(0)
Me.ComboBox2.DisplayMember = "MODEL_DESCRIPTION"

Forget it. It was not in my bin folder.

<smacks forehead> So you just forgot about putting the file in your Resources, huh?
