如何操作指向一内存空间的 HGLOBAL handle ？

[more_chan]

查msdn查到下面一段话，但仍不知该怎么操作：

m_hData stores a Windows HGLOBAL handle to the actual binary large object data.

Work with the data in the object through m_hData, using the same techniques you would normally use to manipulate the data stored in a Windows HGLOBAL handle.

还望各位大虾指点。多谢！！！！！！

GlobalLock
GlobalUnlock

如果没理解错，就像操作handle一样吧
猜的，没用过

能再详细点吗？
最好能举个例子，谢谢！

HGLOBAL hGlobal;
LPSTR pStr;

hGlobal = GlobalAlloc(GHND,64);
pStr = (LPSTR)GlobalLock(hGlobal);
lstrcpy(pStr,"GlobalAlloc(GHND,...) 之后必须使用 GlobalLock(...) 先锁定对象。");
GlobalUnlock(hGlobal);
GlobalFree(hGlobal);

hGlobal = Global(GPTR,64);
pStr = (LPSTR)hGlobal;
lstrcpy(pStr,"GlobalAlloc(GPTR,...) 之后则可以直接使用对象。");
GlobalFree(hGlobal);
