承接专栏《MFC工控项目实例之八选择下拉菜单添加打钩图标》
1、在主界面添加一个组合框和一个静态文本框。

2、在SEAL_PRESSUREDlg.cpp文件中添加代码

BOOL CSEAL_PRESSUREDlg::OnInitDialog()
{CDialog::OnInitDialog();
...
GetDlgItem(IDC_STATIC_TYPNAME)->SetFont(&m_sFont);	
...
}void CSEAL_PRESSUREDlg::OnTypeChange(UINT nID)
{theApp.m_nProductSel = nID - ID_DEF_PRODUCT+1;CWinApp* pApp = AfxGetApp();pApp->WriteProfileInt("参数","nProductSel1",theApp.m_nProductSel);CString str = theApp.m_allPara[theApp.m_nProductSel].m_strTypeName;SetDlgItemText(IDC_STATIC_TYPNAME,str);}
