1. .NET + SQL SERVER SQL Server +SP4

7. 確定加入六個參考

8. DataGrid Button2

9. DataGrid SQL ServerConnectionDataAdapterDataSetCommandDataGrid

10. code Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim cn As System.Data.SqlClient.SqlConnection ' 宣告 connection 物件 Dim cmd As System.Data.SqlClient.SqlCommand ' 宣告 command 物件 Dim da As System.Data.SqlClient.SqlDataAdapter ' 宣告 dataadapter 物件 ' 建立與 SQL Server 資料庫的連線 ' 產生 connection 物件 cn = New System.Data.SqlClient.SqlConnection("uid=rcjao;pwd=rcjao;database=rcjao;server=MYCHAT- 57ED6516") ' 產生 command 物件 cmd = New System.Data.SqlClient.SqlCommand("select * from myname", cn) ' 產生 dataadapter 物件 da = New System.Data.SqlClient.SqlDataAdapter(cmd) ' 加入新的資料表 ' 宣告並產生 datatable 物件 Dim dt As System.Data.DataTable = New System.Data.DataTable("myname") da.Fill(dt) DataGrid1.DataSource = dt End Sub Imports System.data Imports System.Data.SqlClient

11. 部署與執行

13. 部署與執行 －使用模擬器

16. 部署與執行 －使用 PDA 請注意 PDA 畫面上的訊息 程式並未真正安裝到 PDA 上面

17. 部署至 PDA

18. 建置封包檔 畫面會閃動建置封包檔

19. 建置封包檔－適合各種 PDA

20. 安裝封包檔 點選執行 依照機型複製.CAB 檔案到 PDA 上

21. 執行封包檔

22. 表單顯示與切換

23. 建立新表單

24. 表單方法 Close － 關閉表單 Hide － 隱藏表單 Show － 顯示表單 ‘ Form1 呼叫顯示 Form2 Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click Dim myfrm2 As New Form2 myfrm2.Show() End Sub
