这是我亲自编写的程序，只使用一个键（如空格键）可以输入多位数的输入，在我的项目中使用，感谢程序员联合开发网的支持，贡献出来和大家一块学习。

单击空格键实现单位数的加1，键盘右键实现下一位的输入，左键删除最后一位数、学习如何派生自己的CEdit类 ,如何使CEdit控件的最后一位处于选中状态.-This is what I personally prepared the procedure to use only one button (space bar) to be imported into the median over the importation, in my use of the item, thank programmers working on joint support, and we have contributed a study. Click space bar to achieve the increase in the number of units 1, the keyboard under a right to achieve the import, a button to delete the last few, learning how to derive their CEdit category, how CEdit controls at the last one selected.
