将搜索功能添加到MFC组合框 [英] Adding search functionality to a MFC combo box

问题描述

我需要创建一个组合框，为用户提供自动搜索功能。它应该像我们在Windows运行对话框或Windows搜索对话框中看到的组合框一样。因此，当用户键入字符时，必须显示组合框列表中的所有匹配字符串。



我这样做的想法如下：



1>每次用户编辑组合编辑框时都会收到通知。

2>在编辑处理程序中，获取组合框中的文本。

3>然后搜索组合框列表中的所有条目，并在列表中构建匹配条目的向量。

4>创建一个填充了向量中的字符串的列表框并显示它（与组合框正确对齐）。



有没有更简单的方法可以做到这一点，还是MFC提供了更简单的方法或任何现成的功能，可以完成上述步骤中提到的所有任务？一些示例代码或链接将有所帮助。

解决方案

请参阅这个 [ ^ ]文章。



文章中提供的控件涵盖了您的所有要求，并支持 CEdit 和 CComboBox 。 ：）

我自己使用了相同的技术。 MFC不提供任何现成的功能。

Hi,

I need to create a combo box which provides the auto search feature to a user. Its should behave just like the combo box which we see in the Windows 'Run' dialog or in the windows search dialog. So, as the user types in characters , all the matching strings in the combo box list must be displayed.

MY idea for doing this is as follows:

1> Get notified every time the user edits the combo edit box.
2> In the edit handler, get the text in the combobox.
3> Then search through all entries in the combo box list and build a vector of matching entries in the list.
4> Create a list box populated with the strings in the vector and display it (properly aligned with the combo box).

Is there a simpler way of doing this or does MFC provide a simpler way or any ready made functions which can accomplish all the tasks mentioned in the steps above? Some sample code or links will be helpful.

解决方案

Refer to this[^] article.

The control presented in the article covers all of your requirements and supports both CEdit and CComboBox. :)

I myself had used the same technique. MFC doesn't provide any ready made functions.
