求助：MouseHook

[hejianliangjia]

症状：只收到WM_LBUTTONDOWN,而且很多，收不到WM_LBUTTONUP
Dll源码：
#define EXPORT extern "C" _declspec(dllexport)

#include <windows.h>
#include "CaptureLib.h"
#include "string.h"

#pragma data_seg("shared")
POINT ptBeg={-1,-1};

HHOOK hHook=NULL;
#pragma data_seg()

HINSTANCE hInstDll;


//HookProc

{

if(nCode<0)
return CallNextHookEx(hHook,nCode,wParam,wParam);
switch(wParam)
{
case WM_LBUTTONDOWN:

wsprintf(pstr,L"down%d,%d",ptBeg.x,ptBeg.y);
if(lstrlen(szMsg)+lstrlen(pstr)<200)

break;
default:
return CallNextHookEx(hHook,nCode,wParam,lParam);
}

钩一下WH_GETMESSAGE消息看看能不能行

把MessageBox去掉，要不然都被它屏蔽了
