最近要做的一个界面，由于数据太多且涉及到多个主子关联的表，朋友说用四个DataGrid绑定数据并实现与查询条件的联动，太麻烦而且界面肯定不好看，我用mshtml改造成这样了。
未加载数据的窗体
加载数据后的窗体
步骤：1）用Macromedia Dreamweaver生成一个名为fsallcondition.htm的html文件，源码如下：

关键是：为每个数据区域（Td和Div）定义一个ID，以便在程序中进行引用。
2）建立WinForm窗体，引用Microsoft.mshtml，使用Microsoft Web浏览器加载html文件，"查询"按钮用于调用向html文件中写数据的过程，"页面设置"、"打印预览"及"打印"按钮用以调用html文件中的javascript完成相应的功能。源码如下：

这个过程中发现的两个问题：
1）在页面中加入了<OBJECT classid="CLSID:8856F961-340A-11D0-A96B-00C04FD705A2" height=0 id=wb name=wb width=0></OBJECT>组件后引发了两次awbMain_DocumentComplete事件；
2）调用HTML文件中的Javascript进行打印预览，调出打印预览的窗口是不能最大化的，大小取决于本窗体的大小。
