CRAS

CRAS is an MFC class that incapsulates Windows Remote Access Service procedures. The main CRAS advantage is that it can be used on computers that are connected to the Internet via LAN and do not have RAS installed, since it loads RAS DLLs dynamically.

Create CRAS class instance
Within your code create CRAS class instance and add initialization method calls:

BOOL CRAS::Initialize();

This procedure returns a boolean value indicating whether initialization was successfull. FALSE as it's return value in most cases means that RAS was not installed on this computer.

RAS phonebook access
While initializing CRAS retrieves all Windows phonebook entries and stores them in the private class member; you later can access them with

BOOL CRAS::GetEntryCount();
CString CRAS::GetEntry(ULONG ulIndex);

function members. This can be usefull, e.x., if you want to fill a combobox or listbox where user will be able to select an entry to dial.

Dial an entry
When using these methods compression and extraction are performed with some predefined parameters set in:
BOOL CRAS::Dial

(
CString sEntry,
CString sUserName,
CString sPassword,
CRASCallback pfnCallback,
CString sDomain
);

BOOL CRAS::HangUp();

where sEntry is a phonebook entry to dial, sUserName and sPassword are login and password you are logging into network, and sDomain is required in some cases when you are dialing Windows NT dialup server. CRASCallback type is a pointer to a callback function that will be used when a RAS event (state change in most cases) occures; you can submit NULL in this parameter if you do not need it.
