dsoframer控件学习小结
一、先注册一下DSOFramer.ocx
操作：将.ocx复制到C:\windows\system32目录下，
开始->运行->regsvr32 DSOFramer.ocx , 系统会提示DSOFramer.ocx中的DllRegisterServer成功。
二、添加DSOFramer.ocx到你的项目中
操作：先说明一下，我用VS 2005 ，其他VS版本可能操作会有不同，操作应该也类似自己试试，问题应该不大。
在你要访问DSOFramer.ocx的目录上点选右键菜单中的“添加现有项”，找到DSOFramer.ocx，确定。
三、在网页中加载DSOFramer
新建Office.aspx
添加如下代码：
<object id="MyOffice" name = "MyOffice" style="LEFT: 0px; WIDTH: 100%; TOP: 0px; HEIGHT: 100%"
classid="clsid:00460182-9E5E-11D5-B7C8-B8269041DD57" codebase="dsoframer.ocx#version=2,2,0,0" >
</object>
[注]：VS 2005对语法的要求贼多，什么ID的值要用""括起来啦，<object>不能大写啦，……
没什么大碍，但是很烦人，简直就是微软版的唐僧，我给大家提供的代码是修改过的，VS不会有哪些废话了。
然后再body中加入onload事件的处理函数
<body onload="show_word();">
再在<head></head>中间加入函数体
<script language="javascript" type="text/javascript">
<!--
function show_word() {
var str=window.location.search;
var pos_start=str.indexOf("id")+3;
if (pos_start == 2)
return ;
var id = "http://localhost/Getdc.aspx?id=" + str.substring(pos_start);
document.all. MyOffice.Open( id,false, "Word.Document");
}
// -->
</script>
四、编制Getdc.aspx.cs文件
建立Getdc.aspx文件，VS会同时建立与之关联的Getdc.aspx.cs文件
先加入命名空间
using System.Data.SqlClient;
using System.Data.SqlTypes;
编辑Getdc.aspx.cs的Page_Load函数；
protected void Page_Load(object sender, EventArgs e)
{
int pid = Convert.ToInt32(Request["id"]);
SqlConnection myConnection = new SqlConnection("Data Source=\"localhost\";Initial Catalog=\"demo\";Persist Security Info=True;User ID=demo;Password=demo");//数据库的相关设置自己改吧，我就不废话了
SqlCommand mycommand = myConnection.CreateCommand();
myConnection.Open();
mycommand.CommandText = "SELECT filedata " +
" FROM Table_word WHERE (ID = " + pid.ToString() + ") ";//其中filedata的数据库类型是varbinary(MAX)
SqlDataReader myReader = mycommand.ExecuteReader();
myReader.Read();
SqlBinary binaryStream = myReader.GetSqlBinary(0);
myReader.Close();
myConnection.Close();
Response.BinaryWrite(binaryStream.Value);
}
至此，只要你指定的ID没问题，就应该可以加载Word文档了。
五、建立保存文档的按钮
在Office.aspx中添加按钮
<input id="Button1" type="submit" value="保存" onclick="return Submit_upload_onclick()" />
再建立一个input
<input type="file" name="File" id = "File"/>
然后添加Submit_upload_onclick()函数：
function Submit_upload_onclick() {
var str=window.location.search;
var pos_start=str.indexOf("id")+3;
if (pos_start == 2)
return ;
document.all.MyOffice.HttpInit();
document.all.MyOffice.HttpAddPostCurrFile("File", "");
var id = "http://localhost/Savedc.aspx?id=" + str.substring(pos_start);
document.all.MyOffice.HttpPost(id);
}
六、编制Savedc.aspx.cs文件
建立Savedc.aspx文件，VS会同时建立与之关联的Savedc.aspx.cs文件
先加入命名空间
using System.Data.SqlClient;
using System.Data.SqlTypes;
编辑Savedc.aspx.cs的Page_Load函数；
protected void Page_Load(object sender, EventArgs e)
{
int pid = Convert.ToInt32(Request["id"]);
Byte[] source_bin = Request.BinaryRead(Request.TotalBytes);
//---------------------------------------------------------------------------------------
int i, loop, again = -1, file_begin = -1;
for (i = 0; i < Request.TotalBytes; i++)
{
if (source_bin[i] == 13)
if (source_bin[i + 1] == 10)
break;
}
Byte[] MyHeader = new Byte[i];
for (loop = 0; loop < i; loop++)
MyHeader[loop] = source_bin[loop];
for (i += 2; i < Request.TotalBytes; i++)
{
if (source_bin[i] == 13)
if (source_bin[i + 1] == 10)
if (source_bin[i + 2] == 13)
if (source_bin[i + 3] == 10)
break;
}
file_begin = i + 4;
for (i = file_begin; i < Request.TotalBytes; i++)
{
for (loop = 0; loop < MyHeader.Length; loop++)
if (source_bin[i + loop] != MyHeader[loop])
break;
if (loop >= MyHeader.Length)
{
break;
}
}
Byte[] result = new Byte[i - file_begin];
//这是个不得已的办法，用循环肯定会慢，但我不会其他方法
//希望高手完善
for (loop = file_begin; loop < i - file_begin; loop++)
result[loop - file_begin] = source_bin[loop];
//---------------------------------------------------------------------------------------
//以上代码将word文档从二进制流中提取出来，存储在result[]中，方法虽笨，肯定好使
//本人不懂VB，更不懂Java，
//上面代码是我楞从梁无惧用VB写的无惧上传类V2.0里挑选有用的部分翻译成C#的，泪ing……
//看看人家梁兄，多无私，给同行提供这么好的东东
//我在网上找了N + 1天，就TM没找到C#版的，再泪ing……
//现在提供给大家，希望我是最后一个为此郁闷的人
SqlConnection myConnection = new SqlConnection("Data Source=\"localhost\";Initial Catalog=\"demo\";Persist Security Info=True;User ID=demo;Password=demo");//数据库的相关设置自己改吧
SqlCommand mycommand = myConnection.CreateCommand();
mycommand.CommandText = "UPDATE Table_word SET filedata = @myfiledata , b_finished = 1 WHERE (ID = @myID)";
mycommand.Parameters.Add("@myfiledata", SqlDbType.VarBinary, 0, "filedata");
mycommand.Parameters.Add("@myID", SqlDbType.Int, 4, "ID");
SqlDataAdapter mydpt;
DataSet myds = new DataSet();
mydpt = new SqlDataAdapter("SELECT ID ,filedata , b_finished FROM Table_copy WHERE (ID = " + Request["id"] + ")", myConnection);
myConnection.Open();
mydpt.UpdateCommand = mycommand;
mydpt.Fill(myds);
DataTable mydt = myds.Tables[0];
DataRow myrow;
myrow = mydt.Rows[0];
myrow.BeginEdit();
myrow["filedata"] = result;
myrow.EndEdit();
mydpt.Update(myds);
myConnection.Close();
}
至此，只要你指定的ID没问题，就应该可以保存Word文档了。
protected void Page_Load(object sender, EventArgs e)
