编辑框出现输入光标时,产生的消息.
0x0118 would be the undocumented WM_SYSTIMER, which appears to be used for caret blinks. 0x0118是一个undocument 消息 微软没有记录。 但在一些库的源码中可以看到比如ATL的库文件atlapp.h中如此写到
static BOOL IsIdleMessage(MSG* pMsg)
{
// These messages should NOT cause idle processing
switch(pMsg-message)
{
case WM_MOUSEMOVE:
#ifndef _WIN32_WCE
case WM_NCMOUSEMOVE:
#endif //!_WIN32_WCE
case WM_PAINT:
case 0x0118: // WM_SYSTIMER (caret blink)
return FALSE;
}return TRUE;
} 由此可知0x0118是WM_SYSTIMER 消息 INFO: Windows WM_SYSTIMER Message Is an Undocumented Message Q108938 The information in this article applies to: Microsoft Win32 Software Development Kit (SDK) Microsoft Windows Software Development Kit (SDK) 3.1
SUMMARY The WM_SYSTIMER message in Windows is an undocumented system message; it should not be trapped or relied on by an application. This message can occasionally be viewed in Spy or in CodeView while debugging. Windows uses the WM_SYSTIMER message internally to control the scroll rate of highlighted text (text selected by the user) in edit controls, or highlighted items in list boxes.NOTE: The WM_SYSTIMER message is for Windowss internal use only and can be changed without prior notice.
