In this DLL we are providing a wrapper over four COM components. These components are VCLoginCom, VCOrdersCom, VCReportsCom, and VCStockServiceCom. The methods exposed by this dll are

  ReportCancelledOrders(CHttpServerContext *pCtxt, CString    strCustId, CString strBuySell);  ReportApprovedOrders(CHttpServerContext *pCtxt, CString    strCustID, CString strBuySell);  GetUnapprovedOrders(CHttpServerContext *pCtxt, CString    CustomerId, CString BuySell);  GetStocks(CHttpServerContext *pCtxt);  GetStockPerformance(CHttpServerContext *pCtxt, CString    strStockID);  GetPortfolioInfo(CHttpServerContext *pCtxt, CString    strCustId);  GetCustomerDetails(CHttpServerContext *pCtxt, CString    strCustId);  Logout(CHttpServerContext *pCtxt, CString UserName);  ChangePassword(CHttpServerContext *pCtxt, CString UserName,    CString OldPasswd, CString NewPasswd);  Login(CHttpServerContext *pCtxt, CString UserName, CString    Passwd);  ExecuteOrder(CHttpServerContext *pCtxt, CString CustId, CString    StockId, float fStockPrice, long iQuantity, CString BuySell);  GetStockPrice(CHttpServerContext *pCtxt); 

These methods internally call the methods that are implemented in the COM component. The method name in ISAPI DLL is same as method of COM component for easy mapping.

  UpdateCustomer(CHttpServerContext *pCtxt, CString UserID,    CString OldPasswd, CString NewPasswd, CString Name, CString    Address, double Phone, CString Email, float Margin, float    MinAmount);  ReportCancelledOrders(CHttpServerContext *pCtxt, CString    strCustId, CString strBuySell);  ReportApprovedOrders(CHttpServerContext *pCtxt, CString    strCustID, CString strBuySell);  Login(CHttpServerContext *pCtxt, CString UserName, CString    Passwd);  GetUnapprovedOrders(CHttpServerContext *pCtxt, CString    CustomerId, CString BuySell);  GetCustomerDetails(CHttpServerContext *pCtxt, CString    CustomerId);  GetCustomers(CHttpServerContext *pCtxt);  CancelOrder(CHttpServerContext *pCtxt, long OrderId);  ChangePassword(CHttpServerContext *pCtxt, CString UserName,    CString OldPasswd, CString NewPasswd);  ApproveOrder(CHttpServerContext *pCtxt, long OrderId);  AddCustomer(CHttpServerContext *pCtxt, CString UserID, CString    Passwd, CString Name, CString Address, double Phoneno,    CString Email, float Margin, float MinAmount); 

These methods internally call the methods that are implemented in the COM component. The method name in this ISAPI DLL is the same as the method of the COM component for easy mapping.
