在网上下载了一个PB+SQL程序，有数据库文件，PBL文件，机器上也已经装了PB9.0和SQL2000，求高手提取PB源码

①首先在文件夹中找到后缀为.pbw的文件这是 pb的工程文件(workspace) 如果有，安装完pb9之后应该是这样的图标样子，如下图所示！ 双击就可打开pb源码。

②数据库方面：首先找到数据库文件。sql的数据库文件应该是后缀.sql 的建表sql语句文件.文字部分全部粘贴出来，打开sql 2000的查询分析器： 首先选好数据库名，然后将粘贴好的建表sql放在里面。点执行 。此时sql数据库就建成了.

③然后点击pb9.0中的database 画板。按顺序点击MSS Microsoft SQL Server-右键 new profile-填写你的数据库名 服务器写点(.)即可，表示本地服务器.然后双击就可以看到数据库中的表了。还有问题可以追问.这是大致流程!

有没有pbw文件，如果有，直接双击它就可以打开（当然前提是你装了pb）。

如果没有，就需要你建立一个，以pb9为例：先建工作区，file-new-workspace页-workspace，然后附加应用，file-new-target页-existing Application，然后选中你pbl里的应用程序对象，保存后就ok了。

这是我用来交作业的程序.虽然不是自己写的.传上来再说了.

等我自己的可以用了.再传...
