SendFile 控 件 说 明
1. 功能：
SendFile 可传送（任意形式）单个文件（档），如果为WEB页，则同时可以将其同名 . files目录下的所有文件一起传送。
2、设计思路：
¨ 根据用户选择需要传送的文件，获得文件的一些相关信息（主要是文件名），然后开始传送文件到服务器或者是客户端；
¨ 判断是否存在同名 . files 目录，如果存在的话，则遍历该目录，每获得一个文件名，即将该文件发送；
¨ 遍历结束，释放所有资源。
3、控件使用：
控件有含有唯一一个Daul接口 FileWork ，运行时不可见；该接口含有唯一一个方法 TransDoc 。
TransDoc 参数说明：
¨ BSTR ServerName ：为DOMINO服务器名；
¨ BSTR HostName ： 为主机名或者主机IP地址；
¨ UINT Port ：主机端口号；
¨ BSTR User ：当前用户名；
¨ BSTR Password ：当前用户密码；
¨ BSTR DocFilename ：文件全名；
¨ BSTR uDatabase ：Domino 数据库名；
¨ BSTR uForm ：Domino 表单名；
注：BSTR 为Basic String/Binary String，在VB中表现为String 类型。
4、范例：
下面我给出一个在VB中使用该空间的范例：
¨ 新建一个标准EXE工程；
¨ 在Form上添加一个TEXTBOX，两个COMMAND BUTTON，一个COMMON DIALOG。属性如下：
Control name Property
TextBox txtFilename
Command Button1 caption 浏览…
Command Button2 caption 发送文件
代码：
Private Sub Command1_Click()
CommonDialog1.ShowOpen
txtFilename.Text = CommonDialog1.FileName
End Sub
Private Sub Command2_Click()
FileWork1.TransDoc "Domserver", "10.128.0.3", 1028, "zhangchunye", "zhangchunye", txtFilename.Text, "Test", "Test"
End Sub
现代码：
