    Hi,

    I am trying to load an excel file from vb.net. this is all new to me and I have tried this code :

    VB Code:
    1. Private Sub MenuItem4_Click(ByVal sender As System.Object, ByVal e As System.EventArgs)
    2.         Dim xlbook As Microsoft.Office.Interop.Excel.Application = New Excel.Workbook
    3.         Dim wb As Microsoft.Office.Interop.Excel.Workbook
    4.         Dim filestring As String = ("C:\My Documents\VBA")
    5.         Try
    6.             xlbook = CType(CreateObject("Excel.Application"), Microsoft.Office.Interop.Excel.Application)
    7.  
    8.             wb = xlbook.Workbooks.Open(filestring & "\trial vba.xls")
    9.  
    10.             xlbook.Visible = True
    11.             'wb.Activate()
    12.         Catch ex As Exception
    13.             MessageBox.Show("Error: " + ex.ToString())
    14.         End Try
    15.  
    16.     End Sub

    Re: Cannot load Excel file

    You setting a workbook variable equal to a application object. It needs to be the same.
    VB Code:
    1. Dim xlApp As Microsoft.Office.Interop.Excel.Application
    2. Dim xlbook As Microsoft.Office.Interop.Excel.Workbook
