极为经典的拷屏样例，程序短小精悍，关键是自动存成GIF格式，图像文件字节数很小。通过此例可以学到以下技巧：

1、如何使用API拷屏。

2、如何自动保存文件且保证不重名。

3、如何对保存路径进行确认，同时自动递归建立不存在的路径。

4、如何确认一个文件是否存在，并自动创建不存在的文件。

5、将VB获得的BMP截屏转换成GIF文件。



其中大部分代码为原创，敢说，如此经典的VB截屏样例源码绝无仅有！-Very classic sample screenshots, procedures dapper, the key is automatically saved as GIF format image files very small number of bytes. Can be learned through this case the following skills: 1, how to use the API screenshots. 2, how to automatically save the file and guarantees of non-duplicate names. 3, how to preserve the path to confirm, at the same time the establishment of automatic recursive path does not exist. 4, how to confirm the existence of a file and automatically create a document that does not exist. 5, will be obtained VB Screenshots BMP files into GIF. Most of which code for the original, say, such a classic example VB source code unique Screenshots!
