源代码如下（opendlg_loaddata为TOpenDialog控件的name,ofAllowMultiSelect代表允许多选）：
opendlg_loaddata->Options << ofAllowMultiSelect << ofFileMustExist;
if (opendlg_loaddata->Execute()) {
for (int i = 0; i < opendlg_loaddata->Files->Count; i++) {
ListBox_filelist->Items->Add(opendlg_loaddata->Files->Strings[i]);
}
}
