完成了 3个工程代码拷贝在代码必要的处我都进行了详细注释这里我就不再介绍代码了现在进行最后步模拟从网站WebSite下载升级后

a. 打开projMain.vbp编译该工程并且命名为“主.exe”；

b. 打开projNewMain.vbp编译该工程并且命名为“projNewMain.exe”；

c. 打开projUpdate.vbp打开工具栏上“vb资源编辑器”(若没找到读者需要点击菜单“外接|外接管理器”在打开对话框中选择“vb6资源编辑器”在加载行为中选择“加载/卸载”复选框)在资源编辑器中选择“添加自定义资源 …”在打开对话框中定位到Update文件夹选择projNewMain.exe文件保存该资源文件最后编译该工程并且命名为“Update.exe”

d. 将可执行文件“主.exe”、“Update.exe”拷贝到同个文件夹中运行任个相信读者会看到效果



以上代码比较简单仅供读者分析思路用在实际工程中代码编写时也根本没必要把projNewMain.exe放在资源文件中读者只需将它放在服务器某个位置然后在projUpdate.vbp中相应处写下载代码即可

Ok文章至此编写完成希望对各位读者能有所帮助
