获取
HWND
用API GetConsoleWindow，获取
HINSTANCE
使用GetModuleHandle(NULL)。
比如说:
#include <Windows.h>
#include <tchar.h>
#include <iostream>
#include <map>
using
namespace
std;
namespace
dbsoft
{

> strBmp ):m_hInstance(hInst),m_hWnd(NULL),m_hBitMap(NULL),m_hThread(NULL), \
m_strBmpFile( strBmp )
{
}
~CSplashWindow()
{
Stop();

不要打算用GetWindowLong加参数GWL_HINSTANCE从
HWND
得到
HINSTANCE
，我试过了，不行。
