注
复制代码 代码如下:
<input type="button" name="print" value="预览并打印" onclick="preview()">
复制代码 代码如下:
<script language="javascript">
function preview()
{
bdhtml=window.document.body.innerHTML;
sprnstr="<!--startprint-->";
eprnstr="<!--endprint-->";
prnhtml=bdhtml.substr(bdhtml.indexOf(sprnstr)+17);
prnhtml=prnhtml.substring(0,prnhtml.indexOf(eprnstr));
window.document.body.innerHTML=prnhtml;
window.print();
}

WebBrowser 控件技术
复制代码 代码如下:
<object ID=‘WebBrowser1' WIDTH=0 HEIGHT=0
CLASSID=‘CLSID:8856F961-340A-11D0-A96B-00C04FD705A2'>
//打印
WebBrowser1.ExecWB(6,1);
//打印设置
WebBrowser1.ExecWB(8,1);
//打印预览
WebBrowser1.ExecWB(7,1);
//直接打印
WebBrowser1.ExecWB(6,6);
//自定义类PrintClass
public string DGPrint(DataSet ds)
{
//DGPrint执行的功能：根据DataTable转换成对应的HTML对应的字符串
DataTable myDataTable=new DataTable();
myDataTable=ds.Tables[0];
int myRow=myDataTable.Rows.Count;
int myCol=myDataTable.Columns.Count;
StringBuilder sb=new StringBuilder();
string colHeaders="<html><body>"+"<object ID='WebBrowser' WIDTH=0 HEIGHT=0 CLASSID='CLSID:8856F961-340A-11D0-A96B-00C04FD705A2'VIEWASTEXT></object>" +"<table><tr>";
for(int i=0;i<myCol;i++)
{
colHeaders +="<td>"+ myDataTable.Columns[i].ColumnName.ToString()+"</td>";
}
colHeaders += "</tr>";
sb.Append(colHeaders);
for(int i=0;i<myRow;i++)
{
sb.Append("<tr>");
for(int j=0;j<myCol;j++)
{
sb.Append("<td>");
sb.Append(myDataTable.Rows[i][j].ToString().Trim());
sb.Append("</td>");
}
sb.Append("</tr>");
}
sb.Append("</table></body></html>");
colHeaders=sb.ToString();
colHeaders+="<script languge='javascript'>WebBrowser.ExecWB(6,1); window.opener=null;window.close();</script>";
return(colHeaders);
}
导出到Excel，Word中去打印
复制代码 代码如下:
protected void btnMIME_Click(object sender, System.EventArgs e)
{
BindData();
Response.ContentType = "application/vnd.ms-excel";
Response.AddHeader("Content-Disposition", "inline;filename="+HttpUtility.UrlEncode("下载文件.xls",Encoding.UTF8));
//如果输出为Word，修改为以下代码
//Response.ContentType = "application/ms-word"
//Response.AddHeader("Content-Disposition", "inline;filename=test.doc")
StringBuilder sb=new StringBuilder();
System.IO.StringWriter sw = new System.IO.StringWriter(sb);
S编程客栈ystem.Web.UI.HtmlTextWriter hw = new System.Web.UI.HtmlTextWriter(sw);
sb.Append("<html><body>");
dgShow.RenderControl(hw);
sb.Append("</body></html>");
Response.Write(sb.ToString());
Response.End();
}
protected void btnCom_Click(object sender, System.EventArgs e)
{
ExportToExcel(BindData(),Server.MapPath("ComExcel.xls"));
}
//从DataSet到出到Excel
#region从DataSet到出到Excel
///导出指定的Excel文件
public void ExportToExcel(DataSet ds,string strExcelFileName)
{
if (ds.Tables.Count==0 || strExcelFileName=="") return;
doExport(ds,strExcelFileName);
}
///执行导出
private void doExport(DataSet ds,string strExcelFileName)
{
excel.Application excel= new excel.Application();
int rowIndex=1;
int colIndex=0;
excel.Application.Workbooks.Add(true);
System.Data.DataTable table=ds.Tables[0] ;
foreach(DataColumn col in table.Columns)
{
colIndex++;
excel.Cells[1,colIndex]=col.ColumnName;
}
foreach(DataRow row in table.Rows)
{
rowIndex++;
colIndex=0;
foreach(DataColumn col in table.Columns)
{
colIndex++;
excel.Cells[rowIndex,colIndex]=row[col.ColumnName].ToString();
}
}
excel.Visible=false;
excel.ActiveWorkbook.SaveAs(strExcelFileName+".XLS",Excel.XlFileFormat.xlExcel9795,null,null,false,false,Excel.XlSaveAsAccessMode.xlNoChange,null,null,null,null,null);
excel.Quit();
excel=null;
GC.Collect();//垃圾回收
}
#endregion
利用.Net组件打印
复制代码 代码如下:
XslTransform xslt = new XslTransform();
xslt.Load(Server.MapPath( "StudentsToHTML.xsl") );
XPathDocument XDoc = new XPathDocument(Server.MapPath( "Students.Xml" ));
XmlWriter writer = new XmlTextWriter( server.MapPath("Students.html"), System.Text.Encoding.UTF8 );
xslt.Transform( XDoc, null, writer );
writer.Close();
Response.Redirect("Students.html");
利用ActiveX控件打印

复制代码 代码如下:
//水晶报表的填充，省略连接代码
myReport ReportDoc = new myReport();
ReportDoc.SetDataSource(ds);
Crv.ReportSource = ReportDoc;
//输出为指定类型文件
CrystalDecisions.Shared.DiskFileDestinationOptions DiskOpts = new CrystalDecisions.Shared.DiskFileDestinationOptions();
ReportDoc.ExportOptions.ExportDestinationType = CrystalDecisions.Shared.ExportDestinationType.DiskFile;

PageMargins margins;
margins = ReportDoc.PrintOptions.PageMargins;
margins.bottomMargin = 250;
margins.leftMargin = 350;
margins.rightMargin = 350;
margins.topMargin = 450;
ReportDoc.PrintOptions.ApplyPageMargins(margins);
//应用打印机名称
ReportDoc.PrintOptions.PrinterName = strPrinterName;
// 打印 // 打印报表。将startPageN 和endPageN
// 参数设置为0 表示打印所有页。
ReportDoc.PrintToPrinter(1, false,0,0);
