In other words, you need to write an event handler that calls your CheckDriversLicense method. The event handler method receives a parameter of the type, dataeventArgs. The event handler can set a value in the dataeventArgs structure to accept or reject the record. After you write your event handler method, you connect it to the event by assigning, or adding it to the OnValidatedWrite delegate that is a member of the fmrental table. You write this assignment in the init method of the data source of the fmrental form. This assignment to a delegate might seem odd. After all, we're modifying existing code (fmrental) to add handlers, which contradicts the main value proposition of loose coupling that eventing is supposed to offer.

Then, pdf a query is created with a where clause that designates the requested customer by recId. The call to the firstOrDefault method forces execution of the query. The method assigns the single matching customer to the customer variable. (Null is assigned if the recId value matches no customer.) Finally, the customer data is tested to see if the associated driver's license is valid. (Does the license contain "89"?) Handle the event when a record is added The following subsections provide the following: Explain the upcoming code items and their inter-relationships. Show the code for an event handler. Associate the handler with the event occurrences. Preparatory overview When an attempt is made to add a record to a table, the OnValidateWrite event is raised by dynamics ax before the record is written to the database. You want your CheckDriversLicense method to be called each time on the OnValidateWrite event is raised for the fmrental table. To do this, you now need to write a c method that is invoked by the event, and which calls your checkDriversLicense method.

In the demo data, this is true for Adrian Lannin, / but not for Phil Spencer. Return ntains 89 understand the linq code before proceeding with more C code, verify that you understand the linq code you just added. More details about linq are provided in the technical Concepts guide, so only the basics are described below. First, a provider is created. It provides access to all the microsoft desk Dynamics ax tables. Next, a collection of all customers is created. The customer of interest is retrieved from this collection.

The method must validate the drivers license. To do this, the method must retrieve the drivers license number, which is stored in the customer table. The method is given the recId value writing for the customer record that contains the information required by the method. Your C code uses the dynamics ax linq provider to read from the customer table. For linq to work, you must first add references pointing to the linq assemblies. You environment add these references to the C project named DriversLicenseevaluator. In Solution Explorer, expand the DriversLicenseevaluator project node, right-click references, and then click Add Reference.

Click Browse and then enter the following path: C:Packagesbin In some environments, the location of the packages folder is not on the c: drive. In the file name field, type the pattern *linq*.dll and then press Enter. You'll see a list of assemblies with the name linq in them. From that list, select the following files, and then click Add :. Dll you must also add the support assemblies that contain the common type that you'll use in the code below.

these tools make the development effort easy. The obvious choice would be to leverage visual Studio to write the code. However, in this tutorial your code wont actually call an external service, because the logistics are beyond the scope of the simple lab environment. Instead, we provide a mock implementation of a service call. The goal of this tutorial is to teach an understanding of the current state of C and of interoperability with. Create a c class library, dynamics ax enables you to create a reference from a dynamics ax project to the C class library, or to any other type of C project that generates an assembly. Such references affect the build order.
