Dynamically change Crystal Report data provider from OLEDB to SQLNCLI11 in ASP.Net

How to change crystal report data provider from SQLOLEDB to SQLNCLI11 in vb.net

Currently, I am using oledb connection to print crystal report from asp.net application. 

But i want to change OLEDB connection to sql native client 11.0 dynamically because i have around 250 reports to change.

i am using below code to set database connectivity 

For Each CrTable In .Database.Tables
    crtableLogoninfo = CrTable.LogOnInfo
    With crtableLogoninfo.ConnectionInfo
        .ServerName = strServer
        .DatabaseName = strDatabase
        .UserID = strUserId
        .Password = strPassword
    End With
    CrTable.ApplyLogOnInfo(crtableLogoninfo)
Next
