net实现生成及打印条形码功能 (转）

.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：

        </style>
        <script language="javascript" src="scripts/print.js" charset="gb2312"></script>
        <STYLE> DIV.page { PAGE-BREAK-BEFORE: always } </STYLE>
    </HEAD>
    <body>
        <form id="Form2" method="post" runat="server">
            <span id="message" class="noprint"></span>            
            <br>
            <span id="span" class="noprint"></span>
            <br>
            <br>
            <table border="1" cellspacing="0" cellpadding="0" width="70" bordercolor="#000000">
                <tr>
                    <td>
                        <table>
                            <tr>
                                <td width="100%" valign="top" align="center"><asp:Label id="LblName" runat="server" Font-Size="14px" Font-Bold="True"></asp:Label></td>
                            </tr>
                            <tr>
                                <td width="100%" valign="top">
                                    <p align="right" style="PADDING-RIGHT:5px">
                                        <asp:Image id="ImageCode" runat="server"></asp:Image>
                                    </p>
                                    <P><FONT face="宋体"></FONT></P>
                                </td>
                            </tr>
                        </table>
                    </td>
                </tr>
            </table>
        </form>
    </body>
</HTML>
     后台文件：
 System.Web.UI.WebControls.Image ImageCode;
        protected System.Web.UI.WebControls.Label LblName;
        private void Page_Load(object sender, System.EventArgs e)
        {
            // 在此处放置用户代码以初始化页面
            this.LblName.Text =Request.QueryString["Name"].ToString();
            this.ImageCode.ImageUrl =Request.QueryString["Url"].ToString();
        }      
     引用JS代码：
(name){
            var reg = new RegExp("(^|&)"+ name +"=([^&]*)(&|$)");
            var r = this.substr(this.indexOf("\?")+1).match(reg);
            if (r != null) return unescape(r[2]); 
            return null;
        }        
        
        //创建WebBrowser控件
        var createWebBrowser = function(){
            document.getElementById("span").innerHTML = '<object >;
                
        }
        //创建按钮
        var createButton = function(vID,vValue,eventHandler){    
            var btnButton = document.createElement("INPUT");
            btnButton.type ="Button";
            btnButton.id = vID;
            btnButton.value = vValue;
            btnButton.onclick = eventHandler;
            document.getElementById("span").appendChild(btnButton);
        }
        //创建标签
        var createSpan = function(vID,vValue,eventHandler){    
            var htmSpan = document.createElement("span");
            htmSpan.id = vID;
            htmSpan.innerHTML = vValue;
            if(eventHandler != null)
                htmSpan.onclick = eventHandler;
            document.getElementById("span").appendChild(htmSpan);
        }        
        //创建标签
        var createTextBox = function(vID,vValue,eventHandler,width){    
            var btnButton = document.createElement("INPUT");
            btnButton.type ="text";
            btnButton.id = vID;
            btnButton.value = vValue;
            btnButton.width = width;
            if(eventHandler != null)
                btnButton.onclick = eventHandler;
            document.getElementById("span").appendChild(btnButton);

            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()">
