一个对话框程序,里面添加了CComboBox控件,选择类型为dropdown。 在编辑框上输入字符串str,在下拉列表中添加了一些字符串。现在要做一个类似google搜索一样的功能,当下拉列表中的字符串包含str时,需要将下拉列表弹出来。但是下拉列表一弹出来,光标就不见了,只有移动到对话框外面时才可以看得见光标,我不明白是怎么回事,请高手赐教。

问题解决了,在调用ShowDropDown()函数时,该函数内部做了一个SetCursor()操作,把光标变成了IDI_ICON,只要在ShowDropDown()调用后加上语句SetCursor(LoadCursor(NULL,IDC_ARROW))就可以把光标移动恢复正常了,谢谢大家的帮助

能不能这样考虑:

6楼的方法不行,我个人感觉是不是调用ShowDropDown()函数,这个函数里面进行了一些操作,把鼠标隐藏了。

可能的思路:下拉框出来之后,setfocus到edit框上

如果Combobox不需要编辑,只是起选择作用的话,可以考虑用Drop List属性。
