Dial-Up connection

Environment: VC6.0 Win98

Hi all,

There is a code for Dial-Up connection. Aleksander Mikula had already posted his code for disconnecting dial-up connection. This is other part od same problem (accessing internet via phone line). This task can be done by using CInternetSession::GetFtpConnection() function for example, but only if all parameters in dial-up dialog are present (and then you don't set username, password and phone number programaticaly).

For using this function you must include "ras.h" and "raserror.h" header files and link with rasapi32.lib.

bool  DialUp() 
{    
	RASDIALPARAMS rdParams;
    	rdParams.dwSize = sizeof(RASDIALPARAMS);    
	rdParams.szEntryName[0] = '\0';
    	lstrcpy( rdParams.szPhoneNumber, szPhoneNumberToDial );
    	rdParams.szCallbackNumber[0] = '\0';
    	lstrcpy( rdParams.szUserName, szUserName );
    	lstrcpy( rdParams.szPassword, szPassword );    
	rdParams.szDomain[0] = '\0';
    	HRASCONN hRasConn = NULL;
    	DWORD dwRet = RasDial( NULL, NULL, &rdParams, 0L, NULL, &hRasConn );
    	if ( dwRet == 0 )  
		return true;    
	char  szBuf[256];
	if ( RasGetErrorString( (UINT)dwRet, (LPSTR)szBuf, 256 ) != 0 )
        	wsprintf( (LPSTR)szBuf, "Undefined RAS Dial Error (%ld).", dwRet );
    	RasHangUp( hRasConn );
    	AfxMessageBox( NULL, (LPSTR)szBuf, "Error", MB_OK | MB_ICONSTOP );
    	return false;
}


Note that here I'm using sinhrone version (five parameter of RasDial() is NULL). Updated version can use pointer to RasDialFunc() function instead, and then RasDial() returns immediately and calls RasDialFunc() when WM_RASDIALEVENT is occur.
