用printer对象打印表格

          用printer对象打印表格

   用msflexgrid控件显示的表格，要将它打印出来，最简单的方法是用printform方法，然而这只适合于数据正好能被屏幕显示的，即数据量少的，而且这种打印效果很差。而用printer对象进行打印编程，虽然麻烦点，但效果却是相当不错的，你可以自定义打印格式，打印页数，表格的粗细，字体大小等。实际上用printer对象进行打印编程是比较简单的。

下面我就用一实例来说明:

打印的内容是一张数据表，这里就只有两列数据，包括标题，副标题。(用A4纸打印)

假设数据处在C_DataArray(),和R_DataArray()中C_Name与R_Name分别为两数据项的字段名

Public Sub Printtable()'初始化

Dim printer1 as Printer

Dim pageheaderDim pagefooterDim pageleftDim pagerightDim usewidthDim useheightDim i, j, k As IntegerDim word As StringDim startxDim startyDim startyline             ‘ 用来纪录打印竖线的起点

Dim endyline              ’ 用来纪录打印竖线的末点

设置页面参数
