Additional modules (plugins)

You can use plugins to increase ClubControl client part abilities. Plugins - it is dll libraries which can communicate with client part. Client can inform such plugins about different events - for example client mode switching, internet blocking-unblocking, user registration and so on. So plugins can increase ClubControl abilities.

You can write such plugins yourself.

To do it you have to create dll with one export function - "CallbackProc", which is called by client on different events.

Parameters:

void CallbackProc (PLUGIN_CALL_EVENT pce, void *lpData, DWORD dwDataSize);
pce event
lpData extra data
dwDataSize extra data size
enum PLUGIN_CALL_EVENT
{
pceStartup,
//short
//computer number
//sizeof(short)

pceShutdown,
//int
//return value, if != -1 : ExitWindowsEx parameter
//sizeof(int)

pceEnableInet,
//bool
//true/false
//sizeof(bool)

pceMode,

//int
//#define MODE_NONE 0
//#define MODE_LOCKED 1
//#define MODE_USER 2
//#define MODE_ADMIN 3

//#define MODE_LAST MODE_ADMIN
//#define MODE_TOTAL MODE_NONE

//#define MODE BYTE

//sizeof(MODE)

pceUser
//char*
//new user
//string len + 1

}

As an example we give C++ (MS VC 6.0) sources of dll library, which sends network commands when internet is blocked or unblocked. It can be used to operate Unix firewall.

there are two code variants (second is commented), both sends filled structure:

struct INET_DATA
{
DWORD pc;
BOOL bInternet;
};

pc - computer number
bInternet - internet status
