Sendfile control
1. Function:
SendFile can be transmitted (arbitrary form) single file (file), if you are a web page, you can transfer it with all the files in the Files directory.
2, design ideas:
¨¨ Depending on the user to select the file you need to transfer, some related information (mainly the file name) is obtained, and then the file to the server or the client;
¨ Judging whether there is the same name. Files directory, if there is, traverse the directory, each of the file names, will be sent;
¨ The end of the traversal, release all resources.
3, control usage:
The control has a unique DAUL interface Filework, which is not visible when running; the interface contains a unique method. Transdoc.
TRANSDOC parameter description:
¨ BSTR Servername: For the Domino server name;
¨ BSTR Hostname: For the host name or host IP address;
¨ uint port: Host port number;
¨ BSTR User: Current user name;
¨ BSTR Password: current user password;
¨ BSTR DOCFILENAME: Full name;
¨ BSTR UDATABASE: Domino database name;
¨ BSTR UFORM: Domino form;
Note: BSTR is a Basic String / Binary String, which behaves in the VB as a String type.
4, sample:
Below I give an example of using this space in VB:
¨ Newly built a standard EXE project;
¨ Add a TextBox on Form, two Command Button, a CommON Dialog. The property is as follows:
Control Name Property
Textbox TxtFileName
Command Button1 Caption ...
Command Button2 CAPTION Send File
Code:
Private submmand1_click ()
CommonDialog1.showopen
TXTFILENAME.TEXT = CommonDialog1.FileName
End Sub
Private sub fascist2_click ()
Filework1.transdoc "Domserver", "10.128.0.3", 1028, "Zhangchunye", "Zhangchunye", TXTFileName.Text, "Test", "TEST"
End Sub
Modern code:

IF (! sockclient.connect (m_hostname, port))
{
AfxMessageBox ("Connect to the other machine failed!");
Return 0;
}
m_username = ole2t (user);
m_password = OLE2T (Password);
// Send username and password requirements to log in
// Username and password need to be encrypted. Then send it again.
SockClient.send (m_username, strlen);
SockClient.send (m_password, strlen (m_password));
SockClient.send (m_servername, strlen (m_servername));
SockClient.send (M_Database, Strlen (M_Database));
SockClient.send (M_Form, Strlen (M_Form));
User name and password can be sent by verifying
