Use MSN Instant Messenger software in Vs.net (next)

Receive Message

The way to determine if a new message is received is if the content is a "text" type, and the code is as follows

private void ontextrecieved (Messenger.imsgrimsession s,
Messenger.imsgruser u, string header, string text,
ref bool default)
{
if (header. IndexOf ("Content-type:text/plain")!=-1 &&
U.friendlyname!= "Hotmail")
{
Messagewindow.appendtext (U.friendlyname + ":" + text + "\ r \ n");
CurrentUser = u;
default = FALSE;
}
}


Send a message

Enter the message you want to send to the edit box, and then click the Send button, and the contents of the edit box will be sent by the following code:

private static String Header =
"Mime-version:1.0\r\ncontent-type:text/plain;" +
"Charset=utf-8\r\nx-mms-im-format:" +
"FN=MS%20SHELL%20DLG; ef=; co=0; cs=0; Pf=0\r\n\r\n ";

private void Send_click (object sender, System.EventArgs e)
{
Currentuser.sendtext (header, This.sendText.Text,
Messenger.MMSGTYPE.MMSGTYPE_ALL_RESULTS);

Messagewindow.appendtext ("You say:" + Sendtext.text + "\ r \ n");
}


Update the status of a contact

I used a different icon in the ListView to indicate the corresponding state of the contact. When the constructor is invoked, the status of the contact is set for the first time. Call the Onuserstatuschanged () event to update the status of the contact when the contact state changes.

private void onuserstatechanged (Messenger.imsgruser user,
Messenger.mstate State, ref bool default)
{
for (int i = 0; i < Users.count; i++)
{
if (user = = Users.item (i))
{
ListViewItem item = Userlist.items[i];
Item. ImageIndex = getstateimage (user. State);
}
}
}


Summary
