SendMessage函数的消息编号的说明？ [英] Explanation of SendMessage message numbers?

问题描述

我已经成功地使用Windows的SendMessage函数方法来帮助我做各种事情在我的文本编辑器，但每次我只是复制和粘贴代码别人的建议，我真的不知道这意味着什么。总是有一个参数隐蔽消息号。我怎么知道这些代码编号的意思是让我能真正了解发生什么事，（希望）多一点自给自足的未来？谢谢

最近的例子：

 使用System.Runtime.InteropServices ; 
 
函数[DllImport（user32.dll中）] 
静态外部INT SendMessage函数（IntPtr的的HWND，UINT WMSG，UIntPtr的wParam，lParam的的IntPtr）; 
 
的SendMessage（myRichTextBox.Handle，（UINT）0x00B6，（UIntPtr）0，（IntPtr的）（ -  1））; 
  

解决方案

这是Windows的消息代码。

它们在头文件中定义，一般可翻译为一个包含某种形式与不同的语言。

例如：

WM_MOUSEMOVE =安培; H200

MK_CONTROL =安培; H8

MK_LBUTTON =安培; H1

MK_MBUTTON =安培; H10

MK_RBUTTON =安培; H2

MK_SHIFT =安培; H4

MK_XBUTTON1 =安培; H20

MK_XBUTTON2 =安培; H40

看的 http://msdn.microsoft.com/en-us/library/ms644927（VS.85）的.aspx＃ windows_messages 。

I've successfully used the Windows SendMessage method to help me do various things in my text editor, but each time I am just copying and pasting code suggested by others, and I don't really know what it means. There is always a cryptic message number that is a parameter. How do I know what these code numbers mean so that I can actually understand what is happening and (hopefully) be a little more self-sufficient in the future? Thanks.

Recent example:

using System.Runtime.InteropServices;

[DllImport("user32.dll")]
static extern int SendMessage(IntPtr hWnd, uint wMsg,UIntPtr wParam, IntPtr lParam);

SendMessage(myRichTextBox.Handle, (uint)0x00B6, (UIntPtr)0, (IntPtr)(-1));

解决方案

This is the windows message code.
They are defined in the header files, and generally available translated as an include of some sort with different languages.

example:
WM_MOUSEMOVE = &H200
MK_CONTROL = &H8
MK_LBUTTON = &H1
MK_MBUTTON = &H10
MK_RBUTTON = &H2
MK_SHIFT = &H4
MK_XBUTTON1 = &H20
MK_XBUTTON2 = &H40
