可将输入的任意十进制数转换为你想要任意进制数。(Any input can be converted to decimal you want any decimal.)

用vb自制程序安装界面,有需要的话可作参考,()

说明：  利用matlab的gui设计的带有输入和输出功能的界面图形，实现等距线可视性很强，自己独立编写的数据和图形，学习非常值得(Using GUI of MATLAB to design interface graphics with input and output functions, realizing the visibility of isometric line is very strong, the data and graphics written independently by oneself are very worthwhile to learn.)

VC++从DLL中获得资源的小实例源代码，从DLL中获得背景图像，可者是一个图标资源或是其它类型的文件，总之，学会了一种，就可以举一反三，灵活掌握了。(VC++ from the DLL resources, source code examples to get a background image from the DLL, can an icon resource, or other types of documents, in short, learned, you can learn by analogy, flexibility.)
