与SendMessage相对应的函数是什么,是getmessage吗

[followme002]

不过我用api查询器查询发现他们的要求参数不同,那应该是什么那?

什么意思啊,看不懂

Getmessage的API示例!

[rappercn]

GetMessage
The GetMessage function retrieves a message from the calling thread抯 message queue and places it in the specified structure. This function can retrieve both messages associated with a specified window and thread messages posted via the PostThreadMessage function.

VB4-32,5,6
Declare Function GetMessage Lib "user32" Alias "GetMessageA" (lpMsg As MSG, ByVal hwnd As Long, ByVal wMsgFilterMin As Long, ByVal wMsgFilterMax As Long) As Long

Operating Systems Supported

Requires Windows NT 3.1 or later; Requires Windows 95 or later


Library

User32


Parameter Information

?lpMsg
Points to an MSG structure that receives message information from the thread抯 message queue.

?hWnd
Identifies the window whose messages are to be retrieved. One value has a special meaning:
NULL
GetMessage retrieves messages for any window that belongs to the calling thread and thread messages posted to the calling thread via PostThreadMessage.

?wMsgFilterMin
Specifies the integer value of the lowest message value to be retrieved.

?wMsgFilterMax
Specifies the integer value of the highest message value to be retrieved.


Return Values

If the function retrieves a message other than WM_QUIT, the return value is nonzero.

If the function retrieves the WM_QUIT message, the return value is zero.

If there is an error, the return value is -1. For example, the function fails if hWnd is an invalid window handle.

喔,可是大哥你能不能有点解释啊,用中文,光看例子我实在看不懂

[Sean918]

什么叫　＂与SendMessage相对应的函数＂　？

相对应　是什么意思？

SendMessage　的重点在后面的参数上，发送的消息类型不一样，得到的结果也不一样

[lingweijie]

有没有人能对Public Const中设定的数值的意义进行一下解释啊！　本我急需！
[e-mail]

[followme002]

喔,我的意思是,sendmessage是发送消息的,那也应该有个接收消息的函数吧
