Use API to implement mass mail in VFP
Author: Xie ancient and modern
Contact your email with friends, customer or relatives, have become very popular. Implementing email functions in the management system is clearly a wise move that is suitable for users and market development needs. Of course, it is not difficult to implement email functions, and implement a bulk mail sending function is a greater practical measure. We are fully considering such demand, fully considering such demand, completely considering such demand and fully considering the mass mail transmission. Of course, implementing such a function requires a Windows API function, and many users may feel that the API is very mysterious, and I don't dare to try it easily. In fact, the API function is very powerful, and the implementation of many functions is not. In fact, you can master a certain law, the API is not so difficult. The following brief explains how to implement it.
Batch mail sending forms (as shown)
Contains four command buttons ("Select Mail Table", "Confirm Mail List", "Go to Mail Processor", "Exit"), two tags, a drop-down combo box, an edit box, a text box (with The pull-down combination frame is combined). The process is like this: the program first detects whether there is an open table, if there is, no prompt, no prompts that have not been opened, you can click "Select Include Mail Table", select a data table to open. In the future, you can select a field containing the email address from the drop-down combo box, and then click the "OK Mail List", filter the qualified mail address, which appears in the edit box. If you want to delete or add an email address, you can do it in the edit box. Next click "Go to Mail Processor", these email addresses will be accepted as "Recipient" by the system default mail acceptance and sender such as Foxmail, Outlook and other programs, and the message editing window appears in the edit window. It can be convenient to write a letter! Hereinafter, the core code will be described in turn.
