I have used emailing codes for VB and whenver i try to send emails, outlook gives me this error statement:
"No transport provider was available for delivery to this recipient."
I do not know how to fix this problem and it would be very helpful if someone can show me why I'm getting this error.
Additionally, I was wondering if anyone knows how to send emails directly, because most of the codes for emailing I think only puts the letters in the outbox of outlook

Hi xstopx81,
This is the code for a mailing Activex component. Create a new ActiveX DLL project. Paste the code below in the Class module.Add a reference to MSWinsockLib. Compile the code. To send a mail call the function PleaseSendEmail with the requisite parameters. This mailing component allows you to send one attachment with the mail. However you need to specify the IP address of your mail server as the first parameter of the function PleaseSendEmail.
