char buf[256];
char buf1[256];
SHFILEOPSTRUCT fo;
memset(buf, 0, sizeof(buf));
memset(buf1, 0, sizeof(buf1));
memset(&fo, 0, sizeof(fo));
strcpy(buf, "f:\\source");
strcpy(buf1, "f:\\target");
fo.wFunc = FO_MOVE;//复制是FO_COPY,删除是FO_DELETE;
fo.pFrom = buf;
fo.pTo = buf1;
fo.fFlags = FOF_SIMPLEPROGRESS;
SHFileOperation(&fo);

那么中途想退出的话是不是必须用多线程？

现在要实现拷贝文件的功能,时间较长.不想自己做个进度条,问能不能调用windows中拷贝文件的那个进度条?
---------------------------------------------------------------

Requirements
Version 5.00 and later of Shell32.dll

Windows NT/2000: Requires Windows 2000.
Windows 95/98/Me: Requires Windows Me.

IProgressDialog
The IProgressDialog interface is exported by the progress dialog box object (CLSID_ProgressDialog). This object is a generic way to show a user how an operation is progressing. It is typically used when deleting, uploading, copying, moving, or downloading large numbers of files.

The progress dialog box object creates a modeless dialog box and allows the client to set its title, animation, text lines, and progress bar. The object then handles updating on a background thread and allows the user to cancel the operation. Optionally, it estimates the time remaining until the operation is complete and displays the information as a line of text.

BUG: PROGDLG_NOMINIMIZE Flag in IProgressDialog::StartProgressDialog() Has No Effect

就是从源文件读入一块（建议1024KB)，然后写入目标文件，并同时显示进度，如此重复直到读完

INT64 CopyCoder::Copy2(IO::IStream *inStream, const INT64* inSize, IO::IStream *outStream)
{
INT64 retVal = 0;
INT64 readSize = 0;

const INT64 bufferSize =m_buffer.GetSize();

BYTE *buffer = m_buffer;

const bool limitSize = inSize != NULL;

INT64 bytesLeft = limitSize ? *inSize : bufferSize;
while(true)
{
if(limitSize)
{
if(bytesLeft <= 0)break;
}
else
{
bytesLeft = bufferSize;
}

size_t readBytes = (size_t)Min(bytesLeft, bufferSize);
readBytes = inStream->Read(buffer, readBytes);
if(readBytes == 0)break;
readSize += readBytes;
const size_t writeBytes = outStream->Write(buffer, readBytes);

retVal += writeBytes;
bytesLeft -= readBytes;

if(m_progress != NULL)
{
m_progress->SetProgress(readSize, retVal);
}

}

return retVal;
}

来自于我的程序的一部分，自己修改一下
