问题描述

我想实现自动提示一个comboxbox（WIN32，C ++）或编辑控件。但我不知道如何正确使用接口IAutoComplete。我需要的地方，建议汽车应采取的匹配字符串的自定义列表。但如何与IEnumString实现这个？我发现这个链接，但它不和盘托出：的http://msdn.microsoft.com/en-us/library/windows/desktop/hh127437%28v=vs.85%29.aspx

I am trying to implement auto-suggest for a comboxbox (win32, c++) or an edit-control. But I dont know how to use the interface IAutoComplete correctly. I need a custom list of strings where the matches for auto-suggest should be taken from. But how to implement this with IEnumString? I found this link but it doesnt reveal everything: http://msdn.microsoft.com/en-us/library/windows/desktop/hh127437%28v=vs.85%29.aspx

有没有人实现过这个？
Thx提前

Has anybody ever implemented this? Thx in advance Michael

推荐答案

正如我在我的评论指出，ATL有你一pre-写的。

As I noted in my comment, ATL has one pre-written for you.

typedef CComEnum<IEnumString,
                 &IID_IEnumString,
                 LPOLESTR,
                 _Copy<LPOLESTR> > CComEnumString;

CComObject<CComEnumString> *pes;
HRESULT hr = CComObject<CComEnumString>::CreateInstance(&pes);

这code基本上是从的的CComEnum文档。

That code was basically stolen from the CComEnum documentation.
