Accelerator-Table Creation

Several steps are required to create an accelerator table for an application. First, a resource compiler is used to create accelerator-table resources and to add them to the application's executable file. At run time, the LoadAccelerators function is used to load the accelerator table into memory and retrieve the handle of the accelerator table. This handle is passed to the TranslateAccelerator function to activate the accelerator table.

An accelerator table can also be created for an application at run time by passing an array of ACCEL structures to the CreateAcceleratorTable function. This method supports user-defined accelerators in the application. Like the LoadAccelerators function, CreateAcceleratorTable returns an accelerator-table handle that can be passed to TranslateAccelerator to activate the accelerator table.

Windows automatically destroys accelerator tables loaded by LoadAccelerators. An accelerator table created by CreateAcceleratorTable must be destroyed before an application closes; otherwise, the table continues to exist in memory after the application has closed. An accelerator table is destroyed by calling the DestroyAcceleratorTable function.

An existing accelerator table can be copied and modified. The existing accelerator table is copied by using the CopyAcceleratorTable function. After the copy is modified, a handle of the new accelerator table is retrieved by calling CreateAcceleratorTable. Finally, the handle is passed to TranslateAccelerator to activate the new table.

    Nostalgia .Net     .Net is powerful, but not all-powerful, so sometimes we need to use Win32 API for our .Net applications. It's simple enough with Platform Invoke if you have Win32 skill, but we do not always have time to dig the ancient documentation, declare the special types that are compatible with Win32, find the values of the Win32's constants and so on. Nostalgia .Net offers several simple-to-use classes, and components that will allow you to forget about the headache of Win32 and just use the power of Win32 in your application the same way as you use the native.
