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:
