To do: Creating the Windows shared (folder) with some remarks and password programmatically

To show: The various Windows network management C functions - sharing the resources resources




// Don't forget to link to netapi32.lib

// The return value of share functions code can be found in Network Management Error Codes in MSDN

// For Win Xp Pro, adjust accordingly for other Windows version

#define _WIN32_WINNT 0x0501


#include <windows.h>

#include <stdio.h>

// need netapi32.lib

#include <lm.h>


// Unicode main()...

int wmain(int argc, TCHAR *argv[ ])




DWORD parm_err = 0;

// Some prompt...

if(argc < 5)


printf("Usage: %ls <server_name> <share_name> <share_remark> <share_pass>\n", argv[0]);

printf("Example: %ls mypersonal testshare \"setting shared folder\" 123abc\n", argv[0]);




// Fill in the SHARE_INFO_2 structure.

p.shi2_netname = ((LPWSTR)argv[2]);

p.shi2_type = STYPE_DISKTREE; // disk drive including the directory...

p.shi2_remark = ((LPWSTR)argv[3]); // share remark

p.shi2_permissions = ACCESS_ALL; // all permission

p.shi2_max_uses = -1; // unlimited

p.shi2_current_uses = 0; // no current uses


// Try finding a way to accept the share path through the command line...

p.shi2_path = TEXT("E:\\mytestfolder"); // share path, here we want to share a folder

// make sure the folder is there....

p.shi2_passwd = argv[4]; // password

// Call the NetShareAdd() function, specifying level 2.

res = NetShareAdd(argv[1], 2, (LPBYTE) &p, &parm_err);


// If the call succeeds, inform the user.


printf("%ls share created successfully.\n", p.shi2_netname);

// Otherwise, print an error, and identify the parameter in error.


printf("Failed to create %ls, error: %u parmerr = %u\n", p.shi2_netname, res, parm_err);


return 0;



Output example:

(This program run at the command prompt)



Usage: cplus <server_name> <share_name> <share_remark> <share_pass>

Example: cplus mypersonal testshare "setting shared folder" 123abc


F:\vc2005project\cplus\debug>cplus mypersonal testshare "test shared folder" xyz123

testshare share created successfully.
