获取丰富的编辑库版本 [英] Get version of rich edit library

问题描述

全部，

是否可以获取程序使用的RichEdit控件的版本？

Is it possible to get the version of the RichEdit control the program uses?

| Version    | Class name    | Library      | Shipped with    | New features
|------------|---------------|--------------|-----------------|    
| 1.0        | "RICHEDIT"    | Riched32.dll | Windows 95      |
| 2.0        | "RichEdit20W" | Riched20.dll | Windows 98      | ITextDocument
| 3.0        | "RichEdit20W" | Riched20.dll | Windows 2000    | ITextDocument2
| 3.1        | "RichEdit20W" | Riched20.dll | Server 2003     |
| 4.1        | "RICHEDIT50"  | Msftedit.dll | Windows XP SP1  | tomApplyTmp
| 7.5        | "RICHEDIT50"  | Msftedit.dll | Windows 8       | ITextDocument2 (new), ITextDocument2Old, Spell checking, Ink support, Office Math
| 8.5        | "RICHEDIT50"  | Msftedit.dll | Windows 10      | LocaleName, more image formats

我知道我可以拥有一些变量，如果 Msftedit.dll 库是否已加载。但是，如果确实加载 RichEd20.dll ，则可以得到RichEdit 2或RichEdit 3的实现。他们是完全不同的。

I know I can just have some variable and assign it appropriately if Msftedit.dll library is loaded or not. However if I do load RichEd20.dll, I can get either RichEdit 2 or RichEdit 3 implementation. And they are quite different. A lot of stuff were added in the latter.

如果我确实加载了 Msftedit.dll ，则有些功能7.5在早期版本（例如自动拼写检查）中将不可用。

If i did load Msftedit.dll, there are features that 7.5 that would not be available in earlier versions (e.g. automatic spell checking).

同一进程甚至可能加载了所有三个DLL，甚至使用了这三个DLL。版本的RichEdit在相同的过程中：

It's even possible that the same process can have all three DLLs loaded, and even using all three versions of RichEdit in the same process:

• RICHEDIT → 1.0


• RichEdit20W → 2.0，3.0


• RICHEDIT50 → 4.1、7.5、8.5

• "RICHEDIT" → 1.0
• "RichEdit20W" → 2.0, 3.0
• "RICHEDIT50" → 4.1, 7.5, 8.5

给出RichEdit控件（例如WinForms RichTextBox ，WPF RichTextBox ，WinRT RichEditBox ，VCL TRichEdit ）是否可以确定RichEdit控件的版本？

Given a RichEdit control (e.g. WinForms RichTextBox, WPF RichTextBox, WinRT RichEditBox, VCL TRichEdit) is there a way to determine the version of a RichEdit control?

或者我可以通过可用的Windows版本以某种方式区分它们吗？

Or maybe I can somehow differentiate them by Windows version where it is available?

推荐答案

如果使用 c ++ 的概念，您可能会发现以下代码段对于读取类名非常有用：

If using c++ you may find the following snippet useful to read out the class name :

  TCHAR className[MAX_PATH];
  GetClassName(GetRichEditCtrl().GetSafeHwnd(), className, _countof(className));

GetRichEditCtrl（）是另一个控件上的函数，您可能需要替换为控件 hwnd 的任何东西。

GetRichEditCtrl() is function on another control, you may need to substitute with whatever gives you a hwnd to the control.

另一种方法是使用工具例如 spy ++ 来检查类名。

Another method is using a tool like spy++ to inspect the class name.
