I am trying to reference the Excel. Application object however when I add the dependencies I still get an error on saying type Excel.application is not defined.  All I would like to do is open the selected Excel File in a vb.net application.

Thanks in advance
Private Sub btnXYZFile_Open_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnXYZFile_Open.Click
        Me.dlgOpenPartfile.InitialDirectory = _Default_Definition_FileOpen_Dir
        If Me.dlgOpenPartfile.ShowDialog(Me) = Windows.Forms.DialogResult.OK Then
            '  Opens the target Excel File
            Dim ExcelObj As New Excel.Application
            Me.dlgOpenPartfile.FileName = "*.xls"

        End If
    End Sub

Open in new window

In .NET, you connect to Excel through an intermediate that has a long namespace. So the code is a little longer than what you might be used to.

Dim ExcelObj As New Microsoft.Office.Interop.Excel.Application

If you would prefer to stick with the shorter declaration, add the following at the top of the code file:

Imports Microsoft.Office.Interop

Doing this, that namespace becomes one of the defaults (akind to the path environment variable for files) and you do not have to specify it everytime that you use an Office object.
