Luke,

 

I noticed that we are no longer getting order confirmation emails since implementing PayPal Standard. I checked the event log, and found these exceptions being logged.

 

<div style="margin: 0in 0in 0pt"><span style="font-size: 8.5pt">Event code: 3005 </span>

Which version of DotShoppingCart are you running? Check web\Store\PaypalIPNHandler.aspx.cs file to see if you have the yellow background lines below.

 

4.01 - yes, I have that code.

Try to copy both web\Store\PaypalIPNHandler.aspx and web\Store\PaypalIPNHandler.aspx.cs files to your server so that it will show the line# when the exception happens again. Please post back the full exception stack and I should be able to find out the root cause.

Well I have both the aspx and aspx.cs files uploaded. This is the complete exception...no lines numbers.

 

<p class="MsoNormal" style="margin: 0in 0in 0pt"><span style="font-family: &quot;Times New Roman&quot;,&quot;serif&quot;; font-size: 12pt">System.Web.HttpUnhandledException: Exception of type 'System.Web.HttpUnhandledException' was thrown. ---> System.NullReferenceException: Object reference not set to an instance of an object. at PaypalIPNHandler.Page_Load(Object sender, EventArgs e) at System.Web.Util.CalliHelper.EventArgFunctionCaller(IntPtr fp, Object o, Object t, EventArgs e) at System.Web.Util.CalliEventHandlerDelegateProxy.Callback(Object sender, EventArgs e) at System.Web.UI.Control.OnLoad(EventArgs e) at System.Web.UI.Control.LoadRecursive() at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) --- End of inner exception stack trace --- at System.Web.UI.Page.HandleError(Exception e) at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) at System.Web.UI.Page.ProcessRequest(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) at System.Web.UI.Page.ProcessRequest() at System.Web.UI.Page.ProcessRequestWithNoAssert(HttpContext context) at System.Web.UI.Page.ProcessRequest(HttpContext context) at ASP.store_paypalipnhandler_aspx.ProcessRequest(HttpContext context) at System.Web.HttpApplication.CallHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) <o:p></o:p></span>

Without line number I cannot help figure out what went wrong. Are you sure both source code files are up on the right location on the server?

Very sure, I even reuploaded the files to be sure...still no line numbers. Then I wrapped the page load event in a try-catch and had the catch email me the exception...no line numbers. If you have any ideas I can add more code to the page.

I think you're right, though I don't know why the number would be invalid. I changed <compilation debug="true"> in the web.config and I got the line numbers. It's failing on this line:

 

trans.Add(order.OrderNumber);

 

I will try-catch and have the system send me the value of strRequest so that you can see it.

It means that PayPal was sending you the notification which was not orignated from the software. I think you can simply ignore it.

Or simply add the yellow lines below to stop the exception.

 

            Order order = Order.Get(orderNumber);
            if (null == order)
                return;
