The above are some of our common special paths, as long as the input in the resource browser can jump to the specific path.

We often use some paths in development, and here we introduce the method of obtaining special paths.

The function to be used here is SHGetSpecialFolderPath, and the prototype is

Boolshgetspecialfolderpath (       hwndhwndowner,       lptstrlpszpath,       int  Nfolder,       Boolfcreate);

Parameter description:

The first parameter of hWndOwner

A handle to the owner window, the client should specify if it displays a dialog box or message box.

The second parameter lpszpath

A pointer to a null-terminated string this receives the drive and path of the the specified folder. This buffer must is at least MAX_PATH characters in size.

A third parameter Nfolder

A CSIDL that identifies the folder of interest. If a virtual folder is specified, the This function would fail.

Fourth parameter Fcreate

Indicates whether the folder should is created if it does not already exist. If This value is nonzero, the folder would be created. If This value is zero, the folder won't be created.
