这几天研究用ASP输出带打印格式的excel文件.原先找到的资料,并按例程试验的是用ASP在后台调用excel对象,在服务器端对excel文件进行处理然后再输出到客户端.
详见:http://www.duoluo.com/webdream/dlog/showlog.asp?cat_id=28&log_id=521
但是实际应用中发现问题.当服务器端正在运行excel或ACCESS程序时,客户端提交建立excel.application对象无法成功.另一种情况,当一个客户端提交请求时,并没有结束时,另一个客户端提交的请求也无法成功!或许这个问题有别的解决方案,但是至少这是不稳定的.
正好我们部门内部网上有相关成功的例子,挖出来看,原来是在客户端建立excel.application的.这样,服务器端不会再冲突.对于客户端,因为是在局域网内运行,客户IE安全级别可以设低,并允许运行相关activeX(就是在IE工具选项中把各类涉及安全的东西都设为允许,具体的哪一项没有去追究),即使没有设置,IE也会弹出警告窗口:"是否允许运行activeX?"
实现的代码和上篇日志差不多,简单的如下:
程序代码:
<script language="vbscript">
set objExcelApp=CreateObject("Excel.Application")
objExcelApp.DisplayAlerts=true
objExcelApp.WorkBooks.Open("http://XXX.XXX.XXX/XXX.xls")
'完整网路地址的xls文件,这个文件已经设置好格式及打印样式,保存在服务器上
set objExcelBook=objExcelApp.ActiveWorkBook
set objExcelSheets=objExcelBook.Worksheets
set objExcelSheet=objExcelBook.Sheets(1)
'====此处为对excel单元格进行填写数据的语句,如果是从数据库提取数据,可由后台程序生成这些语句,ASP中的示列:
'如:response.write "objExcelSheet.Range(""B2"").Value="""&rs("XXX")&""""
'或 objExcelSheet.Range("B2").Value="<%=rs("XXX")%>"
objExcelSheet.Range("B2:k2").Value=Array("Week1","Week2","Week3","Week4","Week5","Week6","Week7")
objExcelSheet.Range("B3:k3").Value=Array("67","87","5","9","7","45","45","54","54","10")
objExcelSheet.Range("B4:k4").Value=Array("10","10","8","27","33","37","50","54","10","10")
objExcelSheet.Range("B5:k5").Value=Array("23","3","86","64","60","18","5","1","36","80")
objExcelSheet.Cells(3,1).Value="InternetExplorer"
objExcelSheet.Cells(4,1).Value="Netscape"
objExcelSheet.Cells(5,1).Value="Other"
'========================================================
'objExcelApp.Quit
'set objExcelApp=Nothing
</script>
上述代码中
'objExcelApp.Quit
'set objExcelApp=Nothing
作为取消执行,因为此处不要关闭excel.applicaition,不然数据填完后,excel会关闭掉.这时在客户端打开的excel文件需要由客户进行修改或打印等操作.
同时objexcelapp对象还有打印设置及进入打印预览界面等方法,可参考相关excel相关资料.
经过实验,这种方法效果很不错,甚至有在客户端打开excel模板文件后,然后一项项填入数据的动态效果,还是很cool的,:D
