WINAPI函数 怎么在放在类中实现 ,想把下面的接口文件封装到一个类中来调用??????

直接封装就可以了
如
class xxxx
{
private:
Handle m_Hdatabase;
public:
xxxx():m_Hdatabase(NULL){}
OpenDatabase(.......){}
CloseDatabase()
{
if(Hdatabase)
{
//调用API
}
}
};

你里面很多函数可以设成static
class A
{
static DWORD WINAPI GetRecordCountEx();
}
调用得时候可以A::GetRecordCountEx();
