请问大家有没有使用复选框的程序示例分享一下，谢谢！

用复选框来做什么，具体说说......

用于组合条件语句生成

* 假设你表单上有check1,check2
* 根据选择,分类统计
thisform.check1.caption = "院系"
thisform.check2.caption = "班级"
local cGroup,cSelect,cSql
cGroup = ""
cSelect = ""
if thisform.check1.value = 1
   cGroup = "院系"
   cSelect = "院系"
endif
if thisform.check2.value = 1
   if !empty(cGroup)
      cGroup = cGroup + "," + "班级"
      cSelect = cSelect + "," + "班级"
   endif
endif
if !empty(cGroup)
   cGroup = " Group by " + cGroup
endif
if !empty(cSelect)
   cSelect = cSelect + ","
endif

TEXT TO cSql TEXTMERGE NOSHOW PRETEXT 4
select <<cSelect>> max(数学) as 数学最高,max(语文) as 语文最高,max(英语) as 英语最高, ;
 min(数学) as 数学最低,min(语文) as 语文最低,min(英语) as 英语最低 from 成绩表 ;
 <<cGroup>>
endtext
messagebox(cSql)  &&观察生成的SQL语句
EXECSCRIPT(cSql)  &&运行SQL语句

筛选框简单的，根据需要一个一个添加复选框控件，在程序中逐个判断复选框的状态。
