is that not normal that can be empty(ParamName=Nothing)? please can you give me a hand

The error is telling you that the object isn't initialized. And it is right. Change your code to the following: impbonrecepReport = New ReportDocument() Dim reportPath As String = Application.StartupPath & "\\" & "ImpBonReception.rpt" impbonrecepReport.Load(reportPath) SetCurrentValuesForParameterField(impbonrecepReport, myArrayList) CrystalReportViewer1.ReportSource = impbonrecepReport Initialize and load your report first, then set the parameter value's and then show it. You'll also have to change ByVal myReportDocument As ReportDocument to ByRef myReportDocument As ReportDocument Or make the sub into a function and return the report at the end. Basicly you passed an empty object to the 'SetCurrentValuesForParameterField'.

The application does not need to know the location of the database it is accessing, that's what the DSN is for. Reconfigure your DSN so that it "points to" the correct location of the database. Then when you create your CRecordset object, reference the correct DSN.

More details about your problem please --- what you HAVE DONE for reading the data from the tables in the database. Maxwell Chen

Surely you must have some kind of API to work with, and which comes with a manual. If you can, you can always use the connection oriented part of X.25, and then it's not much different from TCP/IP. I think. :~ It's been a while since I did X.25. I read about it in the datacom courses at the university, and I briefly came in touch with it for a telecom application I wrote 6, almost 7 years ago.

That'll probably work, but you need to make sure that the format of the text file is understandable by Excel. To verify this, export the Prolog database to a text file and try to open the file via Excel. It will ask you about the delimeters used in the file. If you can successfully open the file via Excel, then you can do the same thing with code. "Opinions are neither right nor wrong. I cannot change your opinion.

You can add/update/delete any type of variable at anytime when you use php sessions. Here's a general take at what I'd do for an e-cart app. Firstly, I'd place all e-cart code in a separate file, that way you can include it in any file you want. (even better, you can make a class for it) include_ecart.php: (not checked for errors) <?php   /* e-cart related functions */   function does_ecart_exist()   {     // if 'ecart' session variable is set, it exists     return (isset($_SESSION['ecart']));   }   function is_item_in_ecart($product_id)   {     // make sure the e-cart exists!     if (!does_ecart_exist())       return (false);     return (isset($_SESSION['ecart'][$product_id]));   }   function add_item_to_ecart($product_id, $product_name, $unit_price, $quantity)   {     // make sure the e-cart exists!     if (!does_ecart_exist())       return (false);     // todo: determine what to do if item already in cart...     // if (is_item_in_ecart($product_id))     // update or return error?     // create an array to hold the product data     $product_data = array('name' => $product_name, 'price' => $unit_price, 'quantity' => $quantity);     // add the product to the e-cart array, using it's id as the key     $_SESSION['ecart'][$product_id] = $product_data;     return (true);   }   function view_ecart_contents()   {     // make sure the e-cart exists!     if (!does_ecart_exist())       return (false);     // grab each item in the cart, and print out data     $product_id = 0;     $product_data = array();     while (list($product_id, $product_data) = each($_SESSION['ecart']))     {       printf('Product Id: %1$s, Name: %2$s, Price: %3$s, Quantity: %4$s',         $product_id,        &n

wotsit.org is a lot better than magic for cracking file formats. ;) My blog.

The file type .dta is too common to identify. It could be a any of several formats. Try opening it in Notepad or a hex editor, then look for identifiable patterns. It may be possible to determine the record structure visually, then you can write a routine to access it. This usually only works on very simple schemas, or on those that are predominantly text, but you just might get lucky. Will Build Nuclear Missile For Food - No Target Too Small
