Crystal Report在.net中的两种显示方式
编写人：CC阿爸
2014-7-29
近来在完成深圳一公司的项目，对方对各方面要求相当严格，一不满意就拒绝签收，为了对修正水晶报表显示及导出的一些小问题，无赖之下，仔细了解一下水晶报表的操作方法，逼苦我们这些苦逼的程序，虽说在以前的项目中，也常使用crystal report 来制作报表。并且针对web与winform 都各有不同的地方。
但总的来讲：显示水晶报表目前使用控件对象的有两种显示方式
1. 使用crystalReportViewer1 来显示报表
2. 使用Crystal ActiveX report viewer 来显示报表
在使用前，先废话一下有关水晶报表的一些版本的问题：
1. 我接触的第一个是7.0的版本。有一些vb程序的程序都在使用这个版本的报表
2. 后来使用上.net开发工具后，直接升到了crystal report 9.0。
3. Vs 2008 内置了10.5的水晶报表。但这个版本在官方是没有的。
因此我制作报表时仍使用的是为10.0
4. 后来水晶报表先后推出了11 2008,现到13，14
5. 最后想说的，这中间sap收购了水晶报表，现查找技术文档只能在sap网站上查找了。
接下来。废话就不多讲了，将我们使用的代码贴出来供大家参考，发扬互联网的共享精神。让苦逼的程序猿们也少走点冤枉路了。
开发环境：vs 2008+crystal report 10
