Description: SUMMARY Since a Visual Basic client doesn t handle events directly from late-bound COM objects, it needs some way to capture all the events and parameters launched by any COM object server instantiated at runtime and not known at design time. This article explains how to build a bridge component that does just that. The bridge component transmits the intercepted event data back to the Visual Basic client using another supporting COM object that is capable of holding event data and attributes. The Visual Basic client receives the notification from the bridge and extracts all the information relative to the event from the supporting object. Platform: |

Description: 开放数据库互连(ODBC)已经成为Client/Server数据库应用系统中访问远程数据库的一个标准。作为强大的前端开发工具,Visual Basic为开发者提供了多种访问ODBC数据源的途径,如JET数据库引擎、ODBC API函数、RDO接口等。比较而言,直接使用ODBC API函数的编程难度最大,但获得的存取数据库的性能也最佳。-Open Database Connectivity (ODBC) has become the Client / Server Database Application Remote Access database standards. As a powerful front-end development tools, Visual Basic developers to provide a variety of ODBC data source access channels such as the JET database engine, ODBC API function, RDO interface. Comparatively speaking, the direct use ODBC API programming the most difficult, but we have gained access to the database of best performance. Platform: |
