'previous code

 'not working
        'Dim str As String
        'str = "D:\NAVEEN KUMAR\DOTNET\windows\WindowsApplication1\WindowsApplication1\csharp.xlsx"
        'con = New OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & str & ";Extended Properties=""Excel 8.0 XMl;HDR=No;IMEX=1""")
        'con = New OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=D:\NAVEEN KUMAR\DOTNET\windows\WindowsApplication1\WindowsApplication1\csharp.xlsx;Extended Properties=\Excel 8.0; HDR=No; IMEX=1\")


'if u get any error like notfound installed isam means simply u have to change your
        'connection string insted of ur`s please paste below code and change microsoft excel or acess db to 97-2003 format
        con = New OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0;Data Source=D:\NAVEEN KUMAR\DOTNET\windows\WindowsApplication1\WindowsApplication1\123.xls;Extended Properties=""Excel 12.0 Xml;HDR=YES""") '

Change connection string like this
connectionstring=" Provider=Microsoft.ACE.OLEDB.12.0;Data Source=D:\NAVEEN KUMAR\DOTNET\windows\WindowsApplication1\WindowsApplication1\123.xls;Excel 12.0 Xml;HDR=YES"

Try this , it helpt me.

In a connection string you use |DataDirectory| to represent the program folder.

connectionstring=" Provider=Microsoft.ACE.OLEDB.12.0;Data Source=|DataDirectory|\123.xls;Excel 12.0 Xml;HDR=YES"

Don't use Jet. Use ACE

Provider=Microsoft.ACE.OLEDB.12.0;Data Source=D:\DOCUMENTS\PROJECTS\Company List\Customer List1.xls;Extended Properties="Excel 8.0;HDR=YES";
