Could not find installable ISAM. Server Error in &

Question

I have a access database in web. This file is being uploaded in the web earlier. When I checked the same in web by file manager I could see the file. But when I am trying to read this file using this statement

con.ConnectionString = @"Provider=Microsoft.ACE.OLEDB.12.0;
    Data Source=~\httpdocs\Admin\Acessdatabase\ATT2000.mdb;
    Persist Security Info=False;
    Jet OLEDB:Database Password=; 
    providerName=System.Data.OleDb";

it is giving me error as "Cannot find Instalble ISAM".

Answer 1

I've encountered this error, and I've read this article back and forth but no vain.

Finally, I've understood that the trouble is something with the security. So, my solution was to use the local (default) mdw file (Microsoft Access Workgroup Information) like this:

string strConnectionString = 
    "Provider='Microsoft.Jet.OLEDB.4.0';Data Source=" + p_strFileName +
    ";Jet OLEDB:Database Password=" + p_strDBPassword +
    ";Mode=Share Exclusive;Persist Security Info=True;";

// Important part - using mdw file
strConnectionString += "Jet OLEDB:System Database=" + 
    Environment.GetEnvironmentVariable("APPDATA") + 
    @"\Microsoft\Access\system.mdw";

and use the connection on code:

var conn = new OleDbConnection(strConnectionString);
