如何使用FlashWindowEx?

[xjl2005]

希望有人能帮我看一下代码

void CXChatDlg::FlashWindow()
{
	if(! (GetWindowLong(m_hWnd, GWL_STYLE) & WS_VISIBLE))
	{
		ShowWindow(SW_MINIMIZE);

		CWnd* pParentWnd = GetTopLevelParent();
		if ( HINSTANCE hUser = LoadLibrary( _T("User32") ) )
		{
			BOOL (WINAPI *pfnFlashWindowEx)(PFLASHWINFO pfwi);
			(FARPROC&)pfnFlashWindowEx = GetProcAddress( hUser, "FlashWindowEx" );
			if ( pfnFlashWindowEx )
			{
				FLASHWINFO pFWX;
				pFWX.cbSize		= sizeof(pFWX);
				pFWX.dwFlags	= FLASHW_ALL | FLASHW_TIMERNOFG;
				pFWX.uCount		= 3;
				pFWX.dwTimeout	= 0;
				pFWX.hwnd		= m_hWnd;//pParentWnd->GetSafeHwnd();
				(*pfnFlashWindowEx)( &pFWX );
			}
			FreeLibrary( hUser );
		}
	}
	else
	{
		if ( GetForegroundWindow() != GetTopLevelParent() )
		{
			//CWnd* pParentWnd = GetTopLevelParent();
			if ( HINSTANCE hUser = LoadLibrary( _T("User32") ) )
			{
				BOOL (WINAPI *pfnFlashWindowEx)(PFLASHWINFO pfwi);

				(FARPROC&)pfnFlashWindowEx = GetProcAddress( hUser, "FlashWindowEx" );
				if ( pfnFlashWindowEx )
				{
					FLASHWINFO pFWX;

					pFWX.cbSize		= sizeof(pFWX);
					pFWX.dwFlags	= FLASHW_ALL | FLASHW_TIMERNOFG;
					pFWX.uCount		= 3;
					pFWX.dwTimeout	= 0;
					pFWX.hwnd		= m_hWnd;//pParentWnd->GetSafeHwnd();

					(*pfnFlashWindowEx)( &pFWX );
				}
				FreeLibrary( hUser );
			}
		}
	}
}

你VC6？更新平台SDK包

这个方法是可行的，可是pFWX.dwFlags = FLASHW_ALL | FLASHW_TIMERNOFG;这个宏不可用了,要改成0x00000003.....

VC6
是否是因为平台SDK包版本低无法调用USER32?
