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;
