| 各位观客，大家好！ 这是一个利用LabWindows/CVI制作的不规则界面的播放器的例子，这个例子演示了如何获得不规则界面图形，图形的拖拽，以及个性化菜单的制作过程，其中的媒体播放功能并不是很全面，因为我已经用Windows API函数重新封装了一个全新的MP3、MID、WMA、WAV解码器，并制作成了动态链接库，所以在这里不做过多演示。 本程序只是为了说明LabWindows/CVI的强大功能。但细心的同志很快会发现，其实在LabWindows/CVI中隐藏着数以百计的BUG，而且，有些是致命的硬伤！如果在编写程序时不去触碰它的伤处其实也是一门技巧。 这个程序使用了邦丰公司的播放器的皮肤来创建，用来展现真正复杂界面编程的过程。其中也包含了本人程序制作过程中的一些感想，请大家分享！ 如果有观客对此感兴趣，我们可以进一步讨论！ 程序内容： 1.图片的应用（重点） 2.拖拽效果 3.鼠标按下与抬起事件 4.mciSendString函数的初步使用 5.动画效果 程序的界面如下： 部分代码： #include "mci.h"
