Declaring Context Parameters

Context parameters are utilized in things like automatically generated emails. These emails contain a link referencing a fixed point in the web application. This option removes step-by-step navigation in the application from the user.

Example: Approving a request

A manager receives an email that an employee has been added and can request permissions. The email contains a link to a custom request page with preset data of the new employee.

To disable a context parameter for a module

1. Click in the definition tree view and open the Configuration node.
2. Select the data object UID_PersonWantsOrg in the subnode Context parameters.

   Now you can edit the following settings for this context parameter in Node editor.

   Table 58: Context parameter settings

Executing Microsoft .NET Framework Code

Microsoft .NET FrameworkExecuting Code

The web project defined in the Web Designer is translated by the compiler in C# language. This compiles the complete logic of the definition document into a directly executable Microsoft .NET Framework assembly. It is possible to incorporate your own C# source code into this procedure. This way, you have access to the complete functionality of various execution layers. In this section, it will be explained how you incorporate your own C# source code.

Runtime API

Web Designer objects written in C# code can be integrated directly into the object definition. This makes customizing the web application very flexible.

The web project code uses the Web Designer runtime API. The runtime API supplies the following functionality, which is required for the web project.

• Managing database connections with VI.DB.dll
• Authenticating and authorizing HTTP traffic
• Web controls
• Debugging Web Designer interfaces

The following diagram exemplifies the layer structure of components from the web project to the database.

For detailed information about runtime API classes, see the OneIM_QBM_WebRuntime.chm file.

Integrating Code in Object Definitions

In Web Designer you can insert a C# code snippet in an object’s code using the Code snippet node type.
