實現這個效果

實現對各個宿舍的形象直觀的檢視是否滿足的介面及相關程式碼

用imagelist實現的這個功能 ，感謝 孫哥的無私幫忙。程式碼如下：

 if (tabControl1.SelectedTab == tabPage9)
            {

                this.listView1.View = View.SmallIcon;
                this.listView1.SmallImageList = this.imageList1;

                this.listView1.BeginUpdate();//start

                int num_sushe = pub.findnum("Select count(*) from 宿舍資訊表");//計算宿舍數量，即一共有多少間宿舍
                DataSet ds_sushe = dsinit("select * from 宿舍資訊表");
                progressBar1.Minimum = 0;
                progressBar1.Maximum = num_sushe;
                progressBar1.Step = 1;

                for (int k = 0; k < num_sushe; k++)
                {
                    progressBar1.PerformStep();
                    string area = ds_sushe.Tables[0].Rows[k][1].ToString();  //取到區域資料
                    string sushehao = ds_sushe.Tables[0].Rows[k][3].ToString(); //取到宿舍號
                    int num_manyuan = Convert.ToInt32(ds_sushe.Tables[0].Rows[k][4].ToString());  //取到滿員人數轉化成INT型別
                    ListViewItem lvi = new ListViewItem();
                    lvi.Text = "'" + area + "' '" + sushehao + "'";//取每個宿舍的區域及宿舍號 

                    int num_zhuru = pub.findnum("select count(*) from 員工資訊表 where 入住區域= '" + area + "' and 入住宿舍='" + sushehao + "' and 狀態='正常'");
                    if (num_zhuru < num_manyuan) //   如果查詢到的記錄數=滿員人數
                    {
                        lvi.ImageIndex = 0;
                    }

                    else
                    {
                        lvi.ImageIndex = 1;
                    }
                    this.listView1.Items.Add(lvi);

                }

                this.listView1.EndUpdate();//end
            }
 

public static int findnum(string sqltemp)
        {
            pub.getcon();
            OleDbCommand olecmd = new OleDbCommand(sqltemp, pub.oledb_conn);
            int s = Convert.ToInt32(olecmd.ExecuteScalar());

            pub.oledb_conn.Close();
            return s;


        }
