c++ - VS2010中MFC模板项目的问题

Question

我正在使用 Visual Studio 2010 来试验 MFC。

我已经按照向导创建了一个模板 MFC 项目。我选择了一个基于对话框的应用程序，并取消选中其他选项，例如 ActiveX 控件。

在不做任何代码更改后，我按下 F5，应用程序运行。

然后，使用窗体设计器，我将丰富的编辑控件从工具箱拖到应用程序上。我再次按 F5，应用程序编译但立即退出并显示错误代码 0。

为什么会这样？我做错了什么？

这是包含 RichEdit 时的输出:

所有这些加载错误的发生有点可疑。但是，如果出现问题，为什么会以错误代码 0 退出？

这是成功运行的输出。加载失败仍然发生:

更新 我删除了 RichEdit，并添加了这些其他控件，并且工作正常:

• MFC VSListBox 控件
• 列表控制
• MFC 链接控件
• 网络地址控制

Tangent:为什么 RichEdit2 是表单构建器中唯一可用的 RichEdit？ (我在 Windows 7 上使用 VS 2010)

Answer 1

解决方案:我需要添加这个调用:

LoadLibrary(TEXT("riched20.dll"));

如 MSDN 所述:

In Microsoft Visual Studio 2005 and later, it is possible to add a rich edit control into a dialog template by dragging the control from the toolbox. However, doing this in the dialog editor does not ensure that the required library will be loaded before the control is created. It is necessary to call the LoadLibrary function to load Riched32.dll, Riched20.dll, or Msftedit.dll before the dialog is created.
