This type of fee payer x isn’t recognized by our system – PayPal Adaptive Payments SDK

Hey everyone,

Just another Adaptive Payments SDK error I’ve run into.

Error Id: 560027
This type of fee payer x isn’t recognized by our system

This one is fairly self explanatory, valid values are as follows:

SENDER – Sender pays all fees (for personal, implicit simple/parallel payments; do not use for chained or unilateral payments)
PRIMARYRECEIVER – Primary receiver pays all fees (chained payments only)
EACHRECEIVER – Each receiver pays their own fee (default, personal and unilateral payments)
SECONDARYONLY – Secondary receivers pay all fees (use only for chained payments with one secondary receiver)

This parameter is described in the following documentation: https://developer.paypal.com/docs/classic/api/adaptive-payments/Pay_API_Operation/

Cannot parse *.config file – AdaptivePayments SDK (PayPal)

Hey everyone,

Just working on a small project that uses PayPal’s C# AdaptivePayments SDK. I hit an error while attempting to make the following payment:

var service = new AdaptivePaymentsService();
payResponse = service.Pay(payRequest);
“Cannot parse *.config file. Ensure you have configured the ‘paypal’ section correctly.”

at PayPal.Manager.ConfigManager..ctor()
at PayPal.Manager.ConfigManager.get_Instance()
at PayPal.BasePayPalService..ctor()
at PayPal.AdaptivePayments.AdaptivePaymentsService..ctor()

It turns out that you need to add the following entries to your Web.config:

To get the account information you’ll need to do the following:
– Go to developer.paypal.com
– Login to your sandbox account
– Go to the dashboard
– Select accounts (from the list of all your sandbox accounts)
– Create a new one or select an existing business account
– Click profile
– Click API Credentials

Note that the steps required to get this configuration seem to change all the time. Hopefully this will be enough to get you on the right track.

TF30063: You are not authorized to access asxproject – TFS Online/Visual Studio

Hey everyone,

I ran into the following issue while trying to install the HTML Agility Pack via Nuget today:

TF30063: You are not authorized to access asxproject…

This fixed it for me:
– Go to “Team Explorer”
– Up the very top click on the “Connect to Team Projects” button (power cable looking icon next to the home button)
– Right click on the project and then click connect

Once connected, everything seemed to start working for me again. Check out this stackoverflow post more info: http://stackoverflow.com/a/16700451/522859

Repeat a character x times with c#

Hey everyone,

Just a neat little trick I came across on Stackoverflow, repeating a character x times without using a loop:

string result = new String(‘x’, 5); //xxxxx
string result = new String(‘a’, 3); //aaa

oldIndex must be a valid index in the Children collection (Visual Studio)

Hey everyone,

Just posting this in case anyone else runs into it. After unshelving, the following error kept popping up when I tried to open files using the solution explorer:

oldIndex must be a valid index in the Children collection
Parameter name: oldIndex
Actual value was -1.

I’m still not sure what caused it, but restarting visual studio seems to have fixed it.

Resources for Mocking WCF

Hey everyone,

Just a few links I came across for mocking WCF in case anyone else needs them.

This tutorial was great: http://weblogs.asp.net/cibrax/unit-tests-for-wcf

The only issue being that it was missing a few class definitions (IIncomingWebRequestContext and IOutgoingResponseContext). I got lucky and was able to find full code samples at the following links:

https://code.google.com/p/netfx/source/browse/trunk/Source/ServiceModel/Web/IIncomingWebRequestContext.cs?r=18

http://netfx.googlecode.com/svn-history/r28/trunk/Source/ServiceModel/Web/Wrappers.cs

Just in case these links ever go down:

No Entity Framework provider found for the ADO.NET provider with invariant name ‘System.Data.SqlClient’ – MVC5

Hey everyone,

Just an error I came across while trying to use a new solution project:

No Entity Framework provider found for the ADO.NET provider with invariant name ‘System.Data.SqlClient’

The fix for this was simply to run the following command in the package manager console:

PM> Install-Package EntityFramework

Change Default MVC5 Password Complexity Requirements – Passwords must have at least one non letter or digit character. Passwords must have at least one digit (‘0’-‘9’). Passwords must have at least one uppercase (‘A’-‘Z’)

Hey everyone,

I’ve started on a new MVC5 project and came across the following error message while trying to register a new user:

Passwords must have at least one non letter or digit character.
Passwords must have at least one digit (‘0’-‘9’).
Passwords must have at least one uppercase (‘A’-‘Z’)

While having a secure password is obviously important, I felt that most users would probably find these requirements a little extreme. After a bit of Googling I came across a StackOverflow post that mentioned a config class that you can use to edit these settings:

// App_Start > IdentityConfig.cs

...

// Configure validation logic for usernames
            manager.UserValidator = new UserValidator(manager)
            {
                AllowOnlyAlphanumericUserNames = false,
                RequireUniqueEmail = true
            };
            // Configure validation logic for passwords
            manager.PasswordValidator = new PasswordValidator
            {
                RequiredLength = 6,
                RequireNonLetterOrDigit = true,
                RequireDigit = true,
                RequireLowercase = true,
                RequireUppercase = true,
            };
