VC windows shortcut

Two operations: Create and parse the COM component. Header functions to be added for ishelllink and ipersistfile
Shobjidl. hipersistfile mainly uses two member functions:
1. Save. Save the content to the file
2. Load. Read
Load function prototype
Hresult load (
Lpcolstr pszfilename, // name of the shortcut file, which should be an ANSI character
DWORD dwmode // read mode
);
Dwmode can be set to the following values:
Stgm_read: Read-Only
Stgm_write: Write-only
Stgm_readwrite: Primary member of ishelllink:
1. getarguments: Get the parameter information
2. getdescription: obtains the description (remarks)
3. gethotkey: Get the shortcut key
4. geticonlocation: Get the icon
5. getidlist: Obtain the item identifier list of the target object in the shortcut mode (each object in the Windows Shell, such as a file, directory, or printer, has a unique item identifiler List)
6. getpath: obtain the full path of the target file or directory of the shortcut.
7. getshowcmd: Get the shortcut running mode, such as regular window, to maximize
8. getworkingdirectory: Get the working directory
9. Resolve: attempts to obtain the target object according to certain search rules, even if the target object has been deleted or moved, rename
The following is how to set the corresponding information:
10. setarguments
11. setdescription
12. sethotkey
13. seticonlocation
14. setidlist
15. setpath
16. setrelativepat
17. setshowcmd
18. setworkingdirectory: 1. initialize the COM interface
Ii. Create an ishelllink object
3. Get ipersistfile object interface from the ishelllink object
4. Operate the ishelllink object
5. Release the ipersistfile object interface
6. Release the ishelllink object
VII. Example code for releasing the COM interface:
/*
Note: Create a shortcut on the desktop. The shortcut name is "VC created shortcut". The shortcut points to the application "C:/aa.exe"
Shortcut: None
Shortcut working directory: C :/
Remarks on shortcuts: VC writing and writing
Shortcut running mode: regular window
