Use CRPEngine::LogOnSQLServerWithPrivateInfo to allow the Crystal Report Engine to "piggyback" your application's existing connection to a Server. This lowers the number of connections established by a workstation, reducing application time and network traffic. It also prevents a Crystal Reports LogOff call from disconnecting an application's existing connection to the Server.
BOOL LogOnSQLServerWithPrivateInfo (
const _TCHAR *dllName,
void *privateInfo );
