Multiple-step OLE DB operation generated errors. Check each OLE DB status value, if available. No work was done

Question

I am running following code

/*Fetchinch Last CustID from custMaster*/
int ID = 0;
try
{
     con.Open();
     da = new OleDbDataAdapter("select max(Id) from custMaster",con);
     DataSet ds = new DataSet();
     da.Fill(ds);
     for(int i=0;i<ds.Tables[0].Rows.Count;i++)
        ID=int.Parse(ds.Tables[0].Rows[i][0].ToString());
     con.Close();
}
catch (Exception ex) {}
finally 
{
     con.Close();
}

I am putting debugger from the first statement of try block and finding that error is coming when I am trying to open the connection. Error Text:

Multiple-step OLE DB operation generated errors. Check each OLE DB status value, if available. No work was done.

Connection String is:

"Provider=Microsoft.Jet.OLEDB.4.0;DataSource=E:\NewSoft\Database\TestApp.accdb;Integrated Security=SSPI"

I am using oledb connections.

Answer 1

This can be the result of the error in your connection string. You should try to add

Persist Security Info=True;

Or you might have problems in your registry with your OLE DB provider, which must have OLEDB_SERVICES record. In the registry under HKEY_CLASSES_ROOT\CLSID, find the CLSID of the OLE DB provider and add the following registry value:

Value Name: OLEDB_SERVICES
Data Type: REG_DWORD
Value: 0xFFFFFFFF
