需要在高权限程序开始的地方加入以下代码,指定什么消息可以接受
typedef BOOL (WINAPI *_ChangeWindowMessageFilter)( UINT , DWORD);
BOOL CVistaMsgRecvApp::AllowMeesageForVista(UINT uMessageID, BOOL bAllow)//注册Vista全局消息
{
BOOL bResult = FALSE;
HMODULE hUserMod = NULL;
//vista and later
hUserMod = LoadLibrary( L"user32.dll" );
if( NULL == hUserMod )
{
return FALSE;
}
_ChangeWindowMessageFilter pChangeWindowMessageFilter = (_ChangeWindowMessageFilter)GetProcAddress( hUserMod, "ChangeWindowMessageFilter" );
if( NULL == pChangeWindowMessageFilter )
{
AfxMessageBox(_T("create windowmessage filter failed"));
return FALSE;
}
bResult = pChangeWindowMessageFilter( uMessageID, bAllow ? 1 : 2 );//MSGFLT_ADD: 1, MSGFLT_REMOVE: 2
if( NULL != hUserMod )
{
FreeLibrary( hUserMod );
}
return bResult;
}
