Write the Send image file program in C + + Builder

ICQ can achieve point-to-point data transfer, but if you want to send a multimedia image file to the other side, it is more difficult. However, you can use the C++builder 5.0 control to write an application for sending images.

Open C++builder 5.0, create a new project, add the Nmstrm,nmstrmserv,openpicturedialog control to the FORM1, plus the button control 3, the Label control 1, the Edit Control 2, StatusBar Control 1.

Let's start by recognizing the NMSTRM control, the Nmstrmserv control, and the Openpicturedialog control. The NMSTRM control is a TCP/ip-based control that can receive data streams and then send them to the server over the network. The Nmstrmserv control is a data stream that can be received from the client, which listens only on TCP/IP ports and is not responsible for listening on UDP ports. The Openpicturedialog control is used to open an image file for browsing or editing.

The properties of the various controls are designed as follows:

控件名　　属性　　　 值

Button　name=Button1,Caption=发送
Button　name=Button2,Caption=显示
Button　name=Button3,Caption=打开
