I am using the RasDial API.  

There is a way to force the Ras dial up connection to use a specific IP address (that I set) in the Windows GUI.  

My QUESTION is :  is there a way to do this using the API.  I was looking at rasEntry, but I am not sure if this is correct. Does anyone know how to do this and/or have any sample code to share.  

Thank you very much........

This is the correct place to look for - if 'fdwOptions' specifies RASEO_SpecificIpAddr, RAS tries to use the IP address specified by ipaddr as the IP address for the dial-up connection.

hi jkr,

   Thank you....  Do you have any sample code???
I'm going to accept your answer, but sample will help out a lot.  I am a Java programmer and I am not that good with C++ windows API calls.

Thanks again.

Unfortunately not. But, setting that is pretty straightfoward. You'd first get an existing entry and then set the flag and the IP address, e.g.

RASENTRY re;
RASIPADDR ria = { 192, 168, 1, 25};

// get an existing entry
RasGetEntryProperties ( NULL, "The Cool RAS Provider", &re, sizeof ( RASENTRY), NULL, 0);

re.dwfOptions |= RASEO_SpecificIpAddr; // set the flag
re.ipaddr = ria; // and the IP address

// write entry back
RasSetEntryProperties ( NULL, "The Cool RAS Provider", &re, sizeof ( RASENTRY), NULL, 0);
