MFC:

CPadSolderSpec aSpec;void CtestMFCDlg::OnBnClickedOk(){DWORD id1 = ::GetCurrentThreadId();_TCHAR sId1[100];_i64tot_s(id1, sId1,100,16);this->MessageBox(sId1, sId1, MB_ICONINFORMATION);OpenPadSettingDialogByMFC(m_hWnd,&aSpec);DWORD id2 = ::GetCurrentThreadId();_TCHAR sId2[100];_i64tot_s(id2, sId2, 100, 16);this->MessageBox(sId2, sId2, MB_ICONINFORMATION);int a = 1;a++;// TODO: 在此添加控件通知处理程序代码//CDialogEx::OnOK();}

Qt:

CPadSolderSpec aSpec;void MainWindow::on_pushButton3_clicked(){OpenPadSettingDialogByQt(NULL,&aSpec);//OpenPadSettingDialogByQt(this, &aSpec);return;
