Negative Testing For PayPal Using Sandbox - Simulate Different Scenarios?
May 19, 2011
I have a website written in VB.NET that implements PayPal for payments. This is all working fine for successful payments, but I need to be able to simulate scenarios of a failed transaction, pending transaction, etc.
I have read the documentation, which starts on page 47. I enabled Negative Testing in a business account that I created in a Sandbox, but I am not getting desired results.
To simulate an error, as specified in the documentation, I'm passing an error code to Token, which is then used in a request to DoExpressCheckoutPayment - code below - but instead of this raising the error 10417, the response says Invalid Token:
[Code]...
What am I doing wrong in the code above so that I can't trigger a correct error? How do I simulate a response where the status is Pending, Processed, Failed, etc.?
I'm looking into adding some unit tests for some classes in my data access layer and I'm looking at an update routine that has no return value.It simply updates a row based on the id you provide at whichever column name you provide.Inside of this method, we collect the parameters and pass them to a helper routine which calls the stored procedure to update the table.Is there a recommended approach for how to do unit testing in such a scenario?
I use VS team system 2008. At the moment i need to test some business classes, i have found two kinds testing NUnit and the unit testing provided by the VS team system. what are there differences?
I'm building an Active Directory wrapper in VBNET 2.0 (can't use later .NET) in which I have the following:
IUtilisateur IGroupe IUniteOrganisation
These interfaces are implemented in internal classes (Friend in VBNET), so that I want to implement a façade in order to instiate each of the interfaces with their internal classes. This will allow the architecture a better flexibility, etc.Now, I want to test these classes (Utilisateur, Groupe, UniteOrganisation) in a different project within the same solution. However, these classes are internal. I would like to be able to instantiate them without going through my façade, but only for these tests, nothing more.
I am trying to get my PayPal IPN code behind to work, but I've got a couple of compiling errors which I've put a capital letter comment next to. (Sorry about the grammar !)Also, although I pinched the script from the PayPal site, I've had to alter a few little bits. Generally, are there any glaring errors or things I should do differently ?
<code> Imports Microsoft.VisualBasic Imports System Imports System.Data
I want to ask for the steps that i have to do and a code to use for a e-shop using paypal. is there a standard code that it is used for these transactions?
I am using the code below for paypal notifications. I checked the notification history and it comes back as payment_status is Complete BUT the VB code performs the code for the "INVALID" case...
'Post back to either sandbox or live Dim strSandbox As String = "https://www.sandbox.paypal.com/cgi-bin/webscr" Dim strLive As String = "https://www.paypal.com/cgi-bin/webscr" Dim req As HttpWebRequest = CType(WebRequest.Create(strSandbox), HttpWebRequest)
i am going to put a trial version of my applicaton on various websites such as softpedia and download.com....but i heard that you can set up a little website through paypal to sell the downloads of the full version...i have looked around the internet and paypal but not sure how to do something like this...anybody else know?
send data collected from a asp.net web page using vb.net that has a bunch of text boxes for first name, last name, address... item price, quantity, total price... to paypal for processing and settlement?i have never worked with paypal so i am assuming paypal will get this info and generate a bill to send the user.
Using VB MVC 3 with Razor ... can I create the PayPal ipn in any controller? say I put it in its own controller say IPN. Would the URL not then be [URL] ? and if that is correct. Do I need to create a blank view page named Ipn or what ever the Ipn action name is?? In this view would It need to contain any razor syntax? I have been back and fourth over every single post I could find about IPN but there is nothing for MVC 3 vb.net.. This has been edited... I have got the IPN handler reutrning status 200. And when I run it through the tester I get success... However actual test transactions are not being entered in the database...The Ipn Controller function is this:
End Function <AcceptVerbs(HttpVerbs.Post)> Function IPN_Handler(ByVal sender As Object, ByVal e As System.EventArgs) Dim strFormValues As String = Request.Form.ToString()
I was wondering if anyone could please point me in the right direction. I have spent some time looking for answers on the web and not found exactly what I need.in a nutshell:I want my program to be registered once a user enters a serial number of some sort along with their email address. I have an app for my phone and that is what I had to do to get the full version of it.

[code]...Download Transactions Info From Paypal Using VB?
How do I download transactions info from Paypal using VB.NET I want to create an app which when i press a button. It downloads each new Paypal transaction to a textfile. I would like information like purchase item name, item description. And price to be added to textfile. VB.Net in relation to a local computer is something I can work with. Put with intergrating VB.NET with Paypal is alittle out of my depth.
Im making a program that grabs order information from paypal and uploads the info to an FTP server. I already know how to auto login to paypal, and how to write files / upload them to an FTP server, but im having problems with the stuff inbetween.I thought something like this would work (given i made the variables correctly);
but it doesn't, it returns the error with;Now an explanation of what i want it to do;I want it to goto the history page [URL].. and grab the date, name, status (completed or not), and amount values. Then transfers the said values to the variables in the syntax above (d1 / n1 / s1 / a1). After it grabs the values of the new orders, then it goes to the description of everyone, and grabs the text in the subject.
Have my Paypal current balance show up in a textbox on VB.NET using the PayPal API.Not a VB.Net Webbrowser.url...But I keep getting the error Object reference not set to an instance of an object.when I execute this code in VB.NET:[code]
I was wondering if I were to start a new project in vb .net would i be able to have say a user log into the application were their creditionals are stored in a access database (containing their username, password and their payment status) or wherever. (I can do this part easily).
Then have a paypal payment option within the application so a button saying Pay Now or Donate Now, were upon paying the users payment status in the database is changed to 'paid'. I'm sure that if i were to do it through paypal it would send you to their website because of privacy and security.
What I don't understand is how would i be able to send the user from my application to the paypal website and upon paying, have the paypal website return to my application saying that they have paid and the money has went into another paypal account?
I would like to enable my Windows Forms Desktop Application to integrate with PayPal so I can charge my users through the WinForms app. Are there any resources regarding this, or can it be done?
I've been at this for a bit now, and I have tried using google extensively. I have my application set up: it is a HWID System available only to paid subscribers. I want buyers to be able to click on a 'buy now button', and once they successfully pay it automatically adds their information into the database the app uses. This way there is no waiting after payments. I know this is possible, because I've seen it done before - I just can't seem to find how it works?
