OleDbDataReader not reading only???

[atr232000]

Hello all

Can someone please help

I am building an app to read a customers .xls file in to a array list
the array is the being reordered and im writing a file out the back end.

its doing several lookups in the .xls file to see if relivant data is there and it writes a different file (9 different specs) depending what is in each line/column.

Sound simple and I have the app working great however when I use a customers live data I get an ex.message = "Could not decrypt file"

the file opens in excel witthout any password prompts however it does look like the sheet is write protected but all im doing in my app is reading the data.

Any ideas?

            Using fileConn As New OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" & OpenFileDialog1.FileName & "; Extended Properties='Excel 12.0 Xml; HDR=yes; IMEX=1'")

                fileConn.Open()
                ''read the tables as specified
                MyTableName = fileConn.GetSchema("Tables").Rows(0)("TABLE_Name") '1 is the sheet to be read

                Dim OLEDBSearch As OleDbCommand = fileConn.CreateCommand
                OLEDBSearch.CommandText = "SELECT * FROM [" & MyTableName & "];"
                'OLEDBSearch.ExecuteNonQuery()
                Dim OleDBDR As OleDbDataReader = OLEDBSearch.ExecuteReader

                Dim Counter As Integer = 0
                Dim isfirst As Boolean = True

                '' Use the OleDB datareader to read each line 

                While OleDBDR.Read
                    'Counter += 1

                    If OleDBDR.Item(0).ToString.Trim <> "" Then

                        '' Selecting the Currency and Booktype Datareader Items
                        Dim Currency As String = OleDBDR.Item(4).ToString
                        Dim BookType As String = OleDBDR.Item(16).ToString
                        If isfirst Then
                            For intCount As Integer = 0 To OleDBDR.FieldCount - 1

                            Next

                            isfirst = False

                        End If

                        Dim TheLine As String = ""
                        Dim tempstring As String = ""

                        For intCount As Integer = 0 To OleDBDR.FieldCount - 1
                            tempstring &= (OleDBDR.Item(intCount).ToString) & "|"

                        Next
