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...
