IApplicationDestinations::SetAppID method (shobjidl_core.h)
Specifies a unique Application User Model ID (AppUserModelID) for the application from whose taskbar button's Jump List the methods of this interface will remove destinations. This method is optional.
Syntax
HRESULT SetAppID(
[in] LPCWSTR pszAppID
);
Parameters
[in] pszAppID
Type: LPCWSTR
Pointer to the AppUserModelID of the process whose taskbar button representation receives the Jump List.
Return value
Type: HRESULT
If this method succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.
Remarks
If the application has an explicit AppUserModelID, this method must be called before you call RemoveAllDestinations or RemoveDestination.
After an AppUserModelID is specified through an object's SetAppID method, the AppUserModelID is saved in the object for that object's lifetime, providing that it is not overwritten by another call to SetAppID.
Some applications will not declare an explicit AppUserModelID and should not call this method. In that case, the application's identity is deduced when IApplicationDestinations::RemoveDestination or IApplicationDestinations::RemoveAllDestinations are called. However, there is a performance benefit in avoiding those calculations, so applications that provide custom Jump Lists are encouraged to use explicit AppUserModelIDs.
