using System.Configuration.Install;
using System.Linq;

using System.Windows.Forms;


namespace MaterialParametersManagement
{
  [RunInstaller(true)]
  public partial class MyInstaller : Installer
  {
  public MyInstaller()
  {
  InitializeComponent();
  }

  string floderName = "航空材料参数管理系统";

  public override void Install(System.Collections.IDictionary stateSaver)
  {
  try
  {

  base.Install(stateSaver);
  System.Reflection.Assembly Asm = System.Reflection.Assembly.GetExecutingAssembly();//获取当前程序集信息
  System.IO.FileInfo fileinfo = new System.IO.FileInfo(Asm.Location);//获取当前程序集位置

  string dbpath = fileinfo.DirectoryName;//获取文件夹名称


  AttachDB(dbpath);
  }
  catch (Exception e)
  {
  System.Windows.Forms.MessageBox.Show(e.Message);
  }

  }


#region 附加数据库 
  private void AttachDB(string DBPath)
  {
  try
  {
  DataBase DBC = new DataBase();
  DataBase.ConnectionString = "Data Source= localhost\\SQLEXPRESS; Initial Catalog=master; Integrated Security=True";
  DBC.DataBaseName = "MaterialDB2005";
  DBC.DataBase_MDF = DBPath + @"\MaterialDB2005.mdf";
  DBC.DataBase_LDF = DBPath + @"\MaterialDB2005_log.ldf";
  MessageBox.Show(DBC.DataBase_MDF);
  DBC.AddDataBase();
  }
  catch
  {
  MessageBox.Show("附加数据库错误！", "错误", MessageBoxButtons.OK, MessageBoxIcon.Error);
  return;
  }
  }
#endregion
