Joy of Think

当你在按钮上按下鼠标左键不松开，然后移出按钮范围,按钮将从按下状态恢复原状，但是如果将鼠标移回，按钮会变回按下状态。

In windows, I found 3 ways to draw a button:

Using DrawEdge and FillRect
Using GetSysColor() to get need color.

Using DrawFrameControl

Using Theme-Aware API

I decide to use make in win32. First, I try to use NMake, and found a good manual for it: http://web.sau.edu/lilliskevinm/csci240/masmdocs/envtools/26LMAETC16.pdf and http://c2.com/cgi-bin/wiki?UsingNmake.

But in a second thought, I think why I don't use gnumake, I am more familiar with it. There are two major concerns about it:

1, Path seperator
2, Command line length.

I do some google, and found that question 1 has been fixed in special edition for win32 make.
For question 2, I do a little test, write a makefile and echo a big string which contains about 400 bytes. It seems ok. So I decide to try this solution first.
