顺序反了，先捕捉到下拉框，再捕捉滑轮事件，对下拉框进行滚动

是的，WM_COMMAND 是鼠标点击事件，但是对下拉框进行不断滚动、选择、再滚动的操作之后，发现WM_COMMAND事件有时不响应，应该是被阻塞了。

找到了获取下拉框状态的函数了，不需要注册WM_COMMAND消息，但上滑或下划还是不是很灵敏、存在阻塞，代码如下：

你是啥版本？我一运行直接就卡死了。

chamlien 发表于 2017-7-18 19:33:16

最后摸索出来了，原来也很简单，使用_GUICtrlComboBox_GetDroppedState获取到下拉状态，再通过_GUICtrlComboBox_GetCurSel获取当前鼠标选中的索引，最后再用_GUICtrlComboBox_SetCurSel设置需要选中的索引，就达到了滚动的目的了。

关于一次滚动多少个索引，这个可以自己计算，给出的例子只滚动了两屏。这次的滚动比较准确了，也没有出现阻塞的情况。

概念不太一樣吧

WM_COMMAND是下拉觸發一次關閉觸發一次

WM_DRAWITEM應該是一直在畫圖上色吧難道你的那個檢核碼要一直切來切去的
