win32 API窗口句柄的获得——我的经验初次写文档，文笔不通畅的地方，以及理解错误之处望各位朋友多多指正！这篇文章是关于如何获取窗口句柄，以及有哪些函数可供使用的简单讨论！可适用于vc、bcb（其他的我没有试，估计可以），本人在bcb环境下试验。首先我会罗列出一些获取句柄的win32 api 函数，然后简单说说他们的用途！最后说说我是怎么理解和应用的。见笑了！可用的win32 api函数：1.HWND FindWin 阅读详情

case WM_LBUTTONDOWN:

	{

		pt.x=LOWORD(lParam);

		pt.y=HIWORD(lParam);

        }

可是LOWORD下面一直有波浪线啊。。。说未定义标识符lParam。。。求救。。看了几个小时还是弄不出来

        //       determine in which half the click occurred. 

        //   2.  Set the appropriate SPINNERSTATE_*CLICK state 

        //       and repaint that clicked half.  This is another 

        //       example of a change-state-and-repaint strategy. 

        //   3.  Send an initial scroll message. 

        //   4.  Set the mouse capture.
