怎样打印出窗口收到的所有消息？就象spy++那样

[BrownTerran]

也就是说，希望有一个函数，把Message ID转化为字符串

[BrownTerran]

自己顶一下

[真糨糊]

DWORD FormatMessage(
DWORD dwFlags, // source and processing options
LPCVOID lpSource, // message source
DWORD dwMessageId, // message identifier
DWORD dwLanguageId, // language identifier
LPTSTR lpBuffer, // message buffer
DWORD nSize, // maximum size of message buffer
va_list *Arguments // array of message inserts
);

[BrownTerran]

FormatMessage似乎只能将错误码转换成文字描述把，我的是窗口消息ID啊！

用WH_MSGFILTER类型的钩子
/****************************************************************
WH_MSGFILTER hook procedure
****************************************************************/

LRESULT CALLBACK MessageProc(int nCode, WPARAM wParam, LPARAM lParam)
{
CHAR szBuf[128];
CHAR szMsg[16];
CHAR szCode[32];
HDC hdc;
static int c = 0;
size_t cch;
size_t * pcch;
HRESULT hResult;

if (nCode < 0) // do not process message
return CallNextHookEx(myhookdata[MSGFILTER].hhook, nCode,
wParam, lParam);

switch (nCode)
{
case MSGF_DIALOGBOX:
hResult = StringCchCopy(szCode, 32/sizeof(TCHAR), "MSGF_DIALOGBOX");
if (FAILED(hResult))
{
// TODO: write error handler
}
break;

case MSGF_MENU:
hResult = StringCchCopy(szCode, 32/sizeof(TCHAR), "MSGF_MENU");
if (FAILED(hResult))
{
// TODO: write error handler
}
break;

case MSGF_SCROLLBAR:
hResult = StringCchCopy(szCode, 32/sizeof(TCHAR), "MSGF_SCROLLBAR");
if (FAILED(hResult))
{
// TODO: write error handler
}
break;

default:
hResult = StringCchPrintf(szCode, 128/sizeof(TCHAR), "Unknown: %d", nCode);
if (FAILED(hResult))
{
// TODO: write error handler
}
break;
}

// Call an application-defined function that converts a message
// constant to a string and copies it to a buffer.
// 这个函数把消息值转换成字符串，得你自己定义
LookUpTheMessage((PMSG) lParam, szMsg);

hdc = GetDC(hwndMain);
hResult = StringCchPrintf(szBuf, 128/sizeof(TCHAR),
"MSGFILTER nCode: %s, msg: %s, %d times ",
szCode, szMsg, c++);
if (FAILED(hResult))
{
// TODO: write error handler
}
hResult = StringCchLength(szBuf, 128/sizeof(TCHAR), pcch);
if (FAILED(hResult))
{
// TODO: write error handler
}
TextOut(hdc, 2, 135, szBuf, *pcch);
ReleaseDC(hwndMain, hdc);
return CallNextHookEx(myhookdata[MSGFILTER].hhook, nCode,
wParam, lParam);
}

至于怎么把WM_XXXX这样的值转换成"WM_XXXX"字符串我也不知道，哪位高手知道告诉我一下
