.net实现生成及打印条形码功能,本文简单总结了自己的实现方法。
.net实现生成及打印条形码功能,下面简单总结了自己的实现方法。
1.引用dll文件
将FLX.WebControls.dll文件拷贝到顶目的bin文件夹目录中；
2.配置web.config文件
在<system.web></system.web>之间添加如下代码
<httpHandlers>
<add verb="*" path="FlxBarCode.axd" type="FLX.WebControls.FlxBarCodeHandler,FLX.WebControls" />
</httpHandlers>
3.新建aspx文件，代码如下
前台文件：
Code<HTML>
<HEAD>
<title>打印条形码</title>

Code<script language="javascript" type="text/javascript">
function PrintTXM()
{
var name = document.getElementById("TextBox_xm").value;
var txturl = document.getElementById("TextBox_txm").value;
//flxBarcode.axd?Text=11AA0A3B1487A19AB1&Width=60&Height=60
var imageurl = 'flxBarcode.axd?Text='+txturl+'&Width=60&Height=60';
var url = 'gwy_webprint.aspx?Name='+name+'&Url='+imageurl;
window.open(url, "_blank");
}
</script>
<INPUT id="BtnPrint" type="button" value="打印" onclick="PrintTXM()">
