VC中按钮问题

请问在VC中怎样用API创建一个按钮，不要用MFC！即就是说，用createwindow函数创建一个窗口，然后用什么函数能在这个窗体上放置一个按钮？我试过用CBUTTON创建按钮类，但是不行，这又是为什么呢？
注意：不要用MFC 还有，按钮创建后怎么设置按钮响应？？
回复 long12310225：看不懂啊，能不能来点简单的？？
那位可以给出易懂、简单的程序？

这么喜欢用API，你想了解底层是把，好。

Answer 2

进入vc新建win2 application，建立空工程，然后alt+f7，选择使用MFC，才能用mfc编程
"用CBUTTON创建按钮类，但是不行"CBUTTON属于MFC，所以要先设置好允许使用MFC，我不知道，有没有直接生成按钮的API，貌似没有吧。或者特麻烦。我觉得，在win32 application下，允许使用MFC的编程方式最好用

Answer 3

LZ 说的应该是使用 win32 API 直接创建窗体。

具体流程和使用 win32 API 函数创建一个普通窗体一致，创建过程中的设置步骤不同。
按钮也是一种窗体，只是我们在创建过程中让它具有了按钮该有的行为。

win32 API 创建按钮的过程在 《Programming Windows》 里面
Section 1 The Basics
Chapter 9 Child Window Control
The Button Class 一节中有详细的叙述（该书有对应中文版）。
LZ 需要可以发 E-Mail 给我，或者直接从网上下载

Answer 4

不用mfc就用CreateWindow()窗口风格参数里可以|BS_DEFPUSHBUTTON,这样就创建一个可以push的按钮
