IWMDMProgress Interface

The optional, application-implemented IWMDMProgress allows an application to track the progress of operations, such as formatting media or file transfers. This interface is submitted to, and called by, the IWMDMStorageGlobals and IWMDMStorageControl interfaces.
These methods do not provide a way for the application to know which operation is being tracked. However, the IWMDMProgress3 methods do provide a means to identify the operation; if possible, you should implement that interface instead.
In addition to the methods inherited from IUnknown, the IWMDMProgress interface exposes the following methods.
| Method | Description |
| Begin | Indicates that an operation is beginning. An estimate of the duration of the operation is provided when possible. |
| End | Indicates that an operation is finished. |
| Progress | Indicates that an operation is still in progress. |
