一、所谓打包的主要目的：
让用户可以通过运行一个安装程序（我们打好的包）就可以将我们的程序装入系统中正常运行。
所需要为用户考虑的就是简单二字，我认为只要用户通过简单的操作就可以装上我们的系统，那就是一个成功的打包程序。
目前编程技术众多，之前我们要选择适合的技术，如：根据数据量数据库的选用（桌面型\数据服务器\文件..）、数据库连接方式的选择（ADO\BDE\ODBC\DBEXPRSS..）、是否使用注册表、INI文件的使用等。
在做好程序之后，我们只需将程序所需的文件拷贝到另一台电脑上，配置一下相关的系统配置就应当可以运行了。
为什么要打包呢？有些配置方法比较复杂，用户不能接受，少量用户我们亲临现场解决也没问题，当用户量多或其它一些情况下，我们就特别需要制作一个能够自动进行系统配置的文件。
二、简单的分析一下，打包可以分为几块：
1.必要的文件（必须，没它不行！）。
2.数据库连接配置（根据情况：是否使用数据库、系统是否带有数据引擎..）。
3.注册信息（不一定都有，有的程序只需一个EXE，其它什么都不用）。
象安装界面，什么欢迎、许可、口令框之类，我们应当根据具体情况来制定，反正达到上面结果就是目的已经达到。
wise是一个好工具，使用简便。
三、如何包装必须的文件呢？
切换到安装专家页-》安装程序详细资料-》文件，该页有四个框（类似windows的资源管理器），上边两个显示的是我们电脑中的文件，下面是目标电脑的文件夹，从上面的框中选择文件夹或文件，利用添加按钮即可加入目标电脑中。
注意的一点是：
1.application是一个安装时用户选择的目录（也有可能是默认的，在“产品详细信息”中设置）；
2.windows目录是用户机的系统目录，将自动处理；
3.通过双击文件对话框中的文件，可以看到文件的属性，其中有一项是源文件路径，更改路径可以连接到其它文件上，即可以将本机的不同路径下的文件打到同一个目录中，编译时，根据路径提取文件来打包。
四、注册表信息配置：
与上边的对话框非常类似，用法也相似，在上边选择本机的注册表的信息，可以添加到下边来，添加后的信息可以更改键值（与文件不同的是，本机注册表信息修改，不影响该信息的值，而文件是从本机提取的，文件更新，会提取更新后的文件）。
这些注册信息可能与你的出厂的初始设置之类有关，如果嫌麻烦，使用INI也可以，不过我觉得wise的INI设置有点多余，当普通文件打一下也可以。
五、数据库方面：
数据库配置wise有的做的就特别好，如odbc，只要你的本地机配置好了，引用一下就ok了。添加-》导入-》确定，OVER。
至于ADO，在98SE以后的版本中，基本就不用多考虑了。
BDE建议淘汰吧。
六、其它：
快捷方式：添加-》选择要连接的EXE，位置（启动菜单、桌面..），注意的一点是最好加上默认路径，如：
快截方式路径名称：%MAINDIR%\Pricemng.exe
则 默认路径：%MAINDIR%\
原因不在此多谈，暂且告一段落，谢谢读完，希望对大家有用。
我上面漏了说明：
A 程序是必须的，是能够在98/ME/NT/2000/XP下运行的，而B 程序则只能够在NT/2000/XP下运行的，
所以若用户的操作系统是NT/2000/XP下就让其自动安装，若是98/ME的话就不要安装，应该如何实现呢？
