How to use the NMSMTP component ?
I'd like to know how the NMSMTP component (from the FastNet tab in Delphi 5) is used. I want to use it to notify users automatically when their submitted forms are processed by the secretary personnel. The request from the users are sent via a distributed application, the processing is to be done in my application, working together with a MSSQL 7 database.

This solution is only available to members.
To access this solution, you must be a member of Experts Exchange.
one more thing you probably alreadty know is it can be used with the the nmpop3 component (pop to read mail ,smtp to send) ..there is example of all the internet comps in the demos dir.
God knwos what you're talking about with MSSQL and all that but I can help you out with the NMSMTP stuff. The following code simply constructs an NMSMTP component dynamically, connects to the server, builds the mail (using the supplied message) and sends it.
PROCEDURE SendMail(sMSG : STRING);
VAR
SMTP : TNMSMTP;
BEGIN
SMTP := TNMSMTP.Create(nil);
TRY
IF NOT(SMTP.Connected) //We SHOULDN'T be connected but check anyway
THEN
BEGIN
SMTP.Host:= '192.168.0.1'; //Setup the details of the SENDING account
SMTP.UserID := 'neils';
SMTP.Connect;
END;
IF SMTP.Connected //By now we SHOULD be connected but check
THEN
BEGIN
SMTP.ClearParams := TRUE; //Setup the required fields
SMTP.SubType := mtPlain;
SMTP.EncodeType := uuMime;
//The header details MUST be complete so we can stick in some dummy values
SMTP.PostMessage.FromAddre
SMTP.PostMessage.FromName := 'MyProg';
SMTP.PostMessage.ToAddress
SMTP.PostMessage.Body.Text
SMTP.PostMessage.Subject := 'Test Mail';
SMTP.PostMessage.Date := DateToStr(Date);
SMTP.SendMail; //Actually send the mail
END;
IF SMTP.Connected //Tidy up
THEN
SMTP.Disconnect;
FINALLY
SMTP.Free;
END;
END;
All you need to make sure of is that the host and user ID values are correct, and that the header is completed (it'll fail if it isn't). It's then just a case of passing in the subject text, body text, and destination details. If you're sending a lot of emails it would be worth doing the initialisation and connection just once, and keeping the connection open until you've finished.

like i said there is example in the delphi\demos\internet\smtp
i just thought a small peice of code would give the general idea and happened to have the other question opn also...

Sure, no problem - that's what the whole site is about
