在程序中拷贝文件,怎样显示出explorer的拷贝文件的进度对话框?

如题

调用API SHFileOperation(...)，能进行文件拷贝，删除，移动等操作，
同时可以让你控制是否显示相关对话框（进度条，动画，确认等）

详细情况，请参考MSDN

CString strSourcePath = BrowseForFolder("请选择备份数据目录",BIF_RETURNONLYFSDIRS);

if(strSourcePath.IsEmpty())
{
GetDlgItem(IDC_RESTORE_DATABASE)->EnableWindow(TRUE);
return;
}
strSourcePath += "\\*.*";

CString strTargetPath;
GetModuleFileName(NULL, strTargetPath.GetBufferSetLength(_MAX_PATH), _MAX_PATH);
strTargetPath.ReleaseBuffer();

int nFindPos = strTargetPath.ReverseFind('\\');
if(nFindPos != -1)
{
strTargetPath = strTargetPath.Left(nFindPos);
}
strTargetPath = //你要拷贝到的新目录

SHFILEOPSTRUCT FileOperate;
ZeroMemory(&FileOperate,sizeof(FileOperate));

FileOperate.hwnd = NULL;
FileOperate.wFunc = FO_COPY;

char szSourcePath[255] = "\0";
strcpy(szSourcePath,(LPTSTR)(LPCTSTR)strSourcePath);

FileOperate.pFrom = szSourcePath;
FileOperate.pTo = strTargetPath;

FileOperate.fFlags = FOF_NOCONFIRMATION | FOF_NOCONFIRMMKDIR | FOF_ALLOWUNDO;

if(!SHFileOperation(&FileOperate))
{
AfxMessageBox("备份数据已恢复!");
}

考完了最好加上一句SHChangeNotify(SHCNE_UPDATEDIR, SHCNF_PATH, (LPCVOID) strTargetPath, 0);
