Message: [QUOTE="Allan D, post: 2668386"] Hi Jan, Thank you for answering on this thread. It was Rafael who wrote. But Rafael and I get the same error-message. When i save an Excel file i use the mail-menu item called Save as... and then submenu item "Excel Binary Workbook". Then the Save as type, will be preselected to "Excel Binary Workbook (*.xlsb), i choose a filename, and press the button "Save" The same and other machines containing MS Office Excel 2007 can then read the .xslb file without any trouble. But not via the OleDbConnection. I get the Exception with only a few lines of code: Imports System.Data.OleDb Public Sub TestXlsb() Dim connStr As String = "Provider=Microsoft.ACE.OLEDB.12.0;" & _ "Data Source=D:\Myfile.xlsb;" & _ "Extended Properties=""Excel 12.0;HDR=NO;IMEX=1"";" Using conn As OleDbConnection = New OleDbConnection(connStr) conn.Open() 'this line throw an exception. End Using End Sub ...... to me this looks like a well-defined MS Office 2007 Bug. Don't you think so? Best Regards, Allan [/QUOTE]
