是否有可能发送WM_COPY消息，文本复制比剪贴板以外的地方？ [英] Is it possible to send a WM_COPY message that copies text somewhere other than the Clipboard?

问题描述

这是该方法的定义：

  [DllImport("user32.dll")]
    public static extern int SendMessage(IntPtr hWnd, int msg, IntPtr lparam, IntPtr wparam);

这是调用SendMessage函数：

This is the call to SendMessage:

 //WM_COPY = 0x0301
 SendMessage(handle, WM_COPY, IntPtr.Zero, IntPtr.Zero);

这是我如何检索数据：

string text = System.Windows.Forms.Clipboard.GetText();

我希望做同样的事情，只是我不希望将数据复制到剪贴板。是否有可能将数据复制到内存中的其他部分？如果是这样，怎么样？

I'd like to do the same thing except that I don't want the data to be copied to the clipboard. Is it possible to copy the data to some other part in memory? If so, how?

推荐答案

没有。你不能控制什么，当它接收到消息等应用程序就可以了。你得到什么行为目标窗口具有该消息并没有别的（除非你，比你可以自己处理控制目标）。

No. You can't control what other application will do when it receives a message. You get whatever behavior target window has for that message and nothing else (unless you control the target too, than you can handle it yourself).

WM_COPY 只是一个消息（也它是标准之一，意义特别的方式来处理） - 一些窗口将处理它，有些则不会。随着对MSDN WM_COPY 将保存文本编辑控件。

WM_COPY is just a message (also it is standard one and make sense to be handled in particular way) - some windows will handle it, some will not. As defined on MSDN WM_COPY will save text for edit control.

应用程序发送WM_COPY消息发送给编辑控件或组合框中当前选择复制到CF_TEXT格式剪贴板。

An application sends the WM_COPY message to an edit control or combo box to copy the current selection to the clipboard in CF_TEXT format.

如果您正在实现自己的应用程序来处理，无论你想WM_COPY你可以复制数据，也如果子类编辑控制它将使有很大的意义，保持默认的行为...

If you are implementing your own application that handles WM_COPY you can copy data wherever you want, also if sub-classing edit controls it would make a lot of sense to keep default behavior...
