Modifying Proxy setting of IE

[ssudhaiyer]

Hi, I would like to change the proxy settings of IE for dial-up connection. In INTERNET_PER_CONN_OPTION_LIST structure how do I specify the type of connection ? If I specify the connection type as NULL it modifies the global settings. But, I would like to change for dial-up. -Thanks Sudha

I have no idea if this will help! I just did a quick seach of MSDN (for "dial up) and found "Dialing Up the Internet with RAS". INTP

The following snippet does what you want, I guess:

char szConnection[]=...; //name of the dial-up connection
char szProxy[]=...; // in format address:port

INTERNET_PER_CONN_OPTION_LIST List;
INTERNET_PER_CONN_OPTION Option[1];
unsigned long nSize = sizeof(INTERNET_PER_CONN_OPTION_LIST);

Option[0].dwOption = INTERNET_PER_CONN_PROXY_SERVER;
Option[0].Value.pszValue = (LPSTR)szProxy;

List.dwSize = sizeof(INTERNET_PER_CONN_OPTION_LIST);
List.pszConnection = (LPSTR)szConnection;
List.dwOptionCount = 1;
List.dwOptionError = 0;
List.pOptions = Option;

InternetSetOption(NULL, INTERNET_OPTION_PER_CONNECTION_OPTION, &List, nSize);

The proxy is set for all protocols within the connection (HTTP, FTP, etc.) Hope this helps. Joaquín M López Muñoz Telefónica, Investigación y Desarrollo
