1. .NET SQL SERVER
SQL Server +SP4

2. 開啟新專案

3. 加入必要的參考

4. 設計UI

5. DataGrid
SQL Server
Connection
Command
DataAdapter
DataSet
DataGrid

6. 顯示資料按鈕程式碼 Private Sub Button1_Click(…..
Dim cn As System.Data.SqlClient.SqlConnection
Dim cmd As System.Data.SqlClient.SqlCommand
Dim da As System.Data.SqlClient.SqlDataAdapter
' 建立與SQL Server資料庫的連線
cn = New System.Data.SqlClient.SqlConnection("uid=XX;pwd=XX;database=XX;server=XX.XX.XX.XX")
cmd = New System.Data.SqlClient.SqlCommand("select * from XX", cn)
da = New System.Data.SqlClient.SqlDataAdapter(cmd)
' 加入新的資料表
Dim dt As System.Data.DataTable = New System.Data.DataTable(“XX")
da.Fill(dt)
DataGrid1.DataSource = dt
End Sub

7. 表單顯示與切換

8. 建立新表單

9. FORM2按鈕程式碼 Close － 關閉表單 Hide － 隱藏表單 Show － 顯示表單
Private Sub Button2_Click(…..
Form2.Show()
End Sub

10. .NET SQL CE
由SQL Server下載資料

11. 由SQL Server下載資料

12. 加入模組

13. 模組程式碼
Module Module1
Public strremoteconnect As String ' SQL Server連接設定
Public localconnect As String ' sdf檔案位置設定
End Module

14. 由SQL Server下載資料 Form2 設定SQL Server連接參數(strremoteconnect)
設定PDA上SDF檔案位置(localconnect)
Private Sub Form2_Load(…….
strremoteconnect = "provider=sqloledb;data source=XX.XX.XX.XX;Initial Catalog=XX;UID=XX;password=XX"
localconnect = "Data Source=\My Documents\XX.sdf"
End Sub

15. 在PDA建立資料庫 Form2 ' 需要Imports System.IO，檢查sdf資料庫是否存在
If System.IO.File.Exists("\My Documents\XX.sdf") Then
System.IO.File.Delete("\My Documents\XX.sdf")
End If
' 改變游標形狀
System.Windows.Forms.Cursor.Current = System.Windows.Forms.Cursors.WaitCursor
' 建立資料庫
Dim eng As System.Data.SqlServerCe.SqlCeEngine = New System.Data.SqlServerCe.SqlCeEngine(localconnect)
eng.CreateDatabase()
' 恢復油標形狀
System.Windows.Forms.Cursor.Current = System.Windows.Forms.Cursors.Default
MsgBox("資料庫建立成功")

16. 由SQL Server下載資料 Form2 ' 下載資料 Dim strSQL As String = "SELECT * FROM XX"
Dim rda As System.Data.SqlServerCe.SqlCeRemoteDataAccess = Nothing
Try
Button1_Click(sender, e)
rda = New System.Data.SqlServerCe.SqlCeRemoteDataAccess
rda.InternetUrl = "
rda.LocalConnectionString = "Data Source=\My Documents\dmis1.sdf"
rda.Pull(“XX", strSQL, strremoteconnect, System.Data.SqlServerCe.RdaTrackOption.TrackingOnWithIndexes, "ErrorTable")
MsgBox("資料下載成功")
Catch ex As System.Data.SqlServerCe.SqlCeException
MsgBox(ex.Message.ToString)
Finally
rda.Dispose()
End Try

17. 顯示資料
Form2
Dim dt As System.Data.DataTable = New System.Data.DataTable(“XX")
Dim cmd As New System.Data.SqlServerCe.SqlCeCommand
Dim cn As System.Data.SqlServerCe.SqlCeConnection
Dim da As System.Data.SqlServerCe.SqlCeDataAdapter
' 開啟sdf連線
Try
cn = New System.Data.SqlServerCe.SqlCeConnection("Data Source=\My Documents\XX.sdf")
' 使用command執行sql指令
cmd.CommandText = "SELECT * FROM XX"
cmd.Connection = cn
da = New System.Data.SqlServerCe.SqlCeDataAdapter(cmd)
da.Fill(dt)
' 在DataGrid 顯示資料
DataGrid1.Visible = False
DataGrid1.DataSource = dt
DataGrid1.Visible = True
cn.Close()
cn = Nothing
Catch sqlex As System.Data.SqlServerCe.SqlCeException
MsgBox(sqlex.Message.ToString)
Catch ex As Exception
MsgBox(ex.Message.ToString)
End Try

18. 修改資料
Form2
Dim localConnection As System.Data.SqlServerCe.SqlCeConnection
localConnection = New System.Data.SqlServerCe.SqlCeConnection(localconnect)
Dim insertData As String
Dim cmdCreateTable As System.Data.SqlServerCe.SqlCeCommand
insertData = "update XX set XX='11111' where XX=XX"
localConnection.Open()
cmdCreateTable = New System.Data.SqlServerCe.SqlCeCommand(insertData, localConnection)
cmdCreateTable.CommandType = Data.CommandType.Text
cmdCreateTable.ExecuteNonQuery()
localConnection.Close()
localConnection = Nothing

19. 新增資料
Form2
Dim localConnection As System.Data.SqlServerCe.SqlCeConnection
localConnection = New System.Data.SqlServerCe.SqlCeConnection(localconnect)
Dim insertData As String
Dim cmdCreateTable As System.Data.SqlServerCe.SqlCeCommand
' 需要設定SQL Server上的uniqueidentifier的RowGuid=true才可以新增
insertData = "INSERT INTO XX (PayName,PayDescription) VALUES ('小黑','黑強')"
localConnection.Open()
cmdCreateTable = New System.Data.SqlServerCe.SqlCeCommand(insertData, localConnection)
cmdCreateTable.CommandType = Data.CommandType.Text
cmdCreateTable.ExecuteNonQuery()
localConnection.Close()
localConnection = Nothing
MsgBox("新增資料成功")

20. 上傳資料
Form2
Dim rda As System.Data.SqlServerCe.SqlCeRemoteDataAccess = Nothing
Try
rda = New System.Data.SqlServerCe.SqlCeRemoteDataAccess
rda.InternetUrl = "
rda.LocalConnectionString = "Data Source=\My Documents\XX.sdf"
rda.Push(“XX", strremoteconnect, System.Data.SqlServerCe.RdaBatchOption.BatchingOn)
MsgBox("資料上傳成功")
Catch ex As System.Data.SqlServerCe.SqlCeException
MsgBox(ex.Message.ToString)
Finally
rda.Dispose()
End Try
