IHttpContext::GetApplication Method

Retrieves the application container for the current context.

Syntax

virtual IHttpApplication* GetApplication(  
   VOID  
) = 0;

Parameters

This method takes no parameters.

Return Value

A pointer to an IHttpApplication interface.

Remarks

The GetApplication method returns an IHttpApplication interface that is used to retrieve information about the application that is processing the current request. For example, the IHttpApplication::GetApplicationId and IHttpApplication::GetApplicationPhysicalPath methods will return the application's identity and physical path.

Note

IHttpContext owns the lifetime of this object. Therefore, you do not free this pointer when you write your application.

Example

The following code example demonstrates how to use the GetApplication method to create an HTTP module that retrieves the physical path for the current request and returns the path to a Web client.

[!code-cppIHttpContextGetApplication#1]

Your module must export the RegisterModule function. You can export this function by creating a module definition (.def) file for your project, or you can compile the module by using the /EXPORT:RegisterModule switch. For more information, see Walkthrough: Creating a Request-Level HTTP Module By Using Native Code.

You can optionally compile the code by using the __stdcall (/Gz) calling convention instead of explicitly declaring the calling convention for each function.
