.net , asp.net Ethiopia

    Hi, all

    I am new to ASP.NET. I am testing an example that inserts a record into an access database. But i have got an error when i browse the sample aspx page from IE 7.

    In the error the line cn.open() is indentified as the source of the error.

    Line 24: 
    Line 25: 			OleDbConnection cn = new OleDbConnection(myConn);
    Line 26: 			cn.Open();
    Line 27: 			OleDbCommand cmd = new OleDbCommand(myQuery, cn);
    Line 28: 			cmd.ExecuteNonQuery();

    And the stack trace is :

    [OleDbException (0x80004005): Unspecified error]
       System.Data.OleDb.OleDbConnection.ProcessResults(Int32 hr) +20
       System.Data.OleDb.OleDbConnection.InitializeProvider() +57
       System.Data.OleDb.OleDbConnection.Open() +203
       TestASPNET.WebForm1.Page_Load(Object sender, EventArgs e) in c:\inetpub\wwwroot\testaspnet\webform1.aspx.cs:26
       System.Web.UI.Control.OnLoad(EventArgs e) +67
       System.Web.UI.Control.LoadRecursive() +35
       System.Web.UI.Page.ProcessRequestMain() +731

    I am testing the page locally. Both .NET 1.1 and 2.0 framworks are  installed on the machine but it seems i am using 1.1 because the versioning info is:

    Version Information: Microsoft .NET Framework Version:1.1.4322.573; ASP.NET Version:1.1.4322.573 .

    One last thing i am using office 2007 and i think .NET framwork 2.0 installed along with it. Actually i am using Microsoft visual studio 2003 for testing my example.

    So please help me out !!

    Hi Baye

     Where is your connection String for Access. What you have hold in the "myConn" string variable. I think that variable hold a wrong connection string.

    For the Framework problem..

    Normally if you create application in 2005 it automatically execute Framework 2.0.

    Yoy can also manually change the Framework in the IIS.

    Hello, Hari

    Thank you for your answer.

    I don't think there is any problem with the connection string variable. Anyway here it is:

    String myConn ="Provider=Microsoft.JET.OLEDB.4.0;Data Source=C:\\Program Files\\Microsoft Visual Studio\\VB98\\Nwind.mdb;";

    String myQuery = "Insert into Customers(CustomerID,CompanyName) Values ('aaaaa', 'aaaaa')";

    Any idea?.
