OleGetClipboard获取FileGroupDescriptorW乱码

[jamseyang]

//////////下面打印cFileName是乱码
MessageBoxW(GetActiveWindow(), filegroup->fgd[i].cFileName, L"test", 0);
代码如下：

// OleGetClipboardTest.cpp : 定义控制台应用程序的入口点。
//

#include "stdafx.h"

在资源管理器中拷贝文件后，再执行程序

[zgl7903]

hGlobal 一般 用 GlobalLock 后再访问 FILEGROUPDESCRIPTORW *filegroup = (FILEGROUPDESCRIPTORW*) GlobalLock(stgmedium.hGlobal); for (UINT i = 0; i < filegroup->cItems; i++) { //////////下面打印cFileName是乱码 MessageBoxW(GetActiveWindow(), filegroup->fgd[i].cFileName, L"test", 0); } GlobalUnlock(stgmedium.hGlobal);

改为这样就可以了

FILEGROUPDESCRIPTORW *filegroup = (FILEGROUPDESCRIPTORW*)GlobalLock(stgmedium.hGlobal);
