WebClass Class

Note: This API is now obsolete.

Enables upgraded Visual Basic 6.0 WebClass projects to run in ASP.NET.


Namespace:  Microsoft.VisualBasic.Compatibility.VB6
Assembly:  Microsoft.VisualBasic.Compatibility (in Microsoft.VisualBasic.Compatibility.dll)

[ObsoleteAttribute("Microsoft.VisualBasic.Compatibility.* classes are obsolete and supported within 32 bit processes only.")]
public class WebClass

The WebClass type exposes the following members.

Public methodWebClassInitializes a new instance of the WebClass class.

Public propertyNameGets the name that is used in code to identify a WebClass object.
Public propertyNextItemGets or sets another WebItem object in the current WebClass object.
Public propertyUrlDataGets or sets a parameter that is appended to the end of any URL that is generated by using the URLFor method.

Public methodEquals(Object)Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetHashCodeServes as a hash function for a particular type. (Inherited from Object.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodProcessEventsRenders a WebItem in a WebClass.
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)
Public methodURLFor(String, String)Specifies the URL that the system must have to reference a WebClass WebItem in the browser.
Public methodURLFor(WebItem, String)Specifies the URL that the system must have to reference a WebClass WebItem in the browser.

When a Visual Basic 6.0 WebClass project is upgraded to Visual Basic 2010, it is converted to an ASP.NET Web-site project.

Declarations are added to your project: one for the WebClass and one for each WebItem and Template in the WebClass project. A Page_Load event procedure is added to the project. This creates first a WebClass object and then WebItem objects for each WebItem and Template associated with the Visual Basic 6.0 WebClass project. Finally, in the Page_Load event procedure, you will see a call to the WebClass Compatibility runtime: ProcessEvents. This enables the runtime to render the WebItem specified in the Request URL. This code is the only new code added to your upgraded project and serves only to emulate the underlying behavior of the Visual Basic 6.0 WebClass runtime.


Functions and objects in the Microsoft.VisualBasic.Compatibility.VB6 namespace are provided for use by the tools for upgrading from Visual Basic 6.0 to Visual Basic 2008. In most cases, these functions and objects duplicate functionality that you can find in other namespaces in the .NET Framework. They are necessary only when the Visual Basic 6.0 code model differs significantly from the .NET Framework implementation.
