復制代碼 代碼如下:

'數據庫連接
Public Sub connectionDB()
Try

serverUrl = readFromIni(My.Application.Info.DirectoryPath & "/config.dll", "Service Information", "IPAddress")

serverID = readFromIni(My.Application.Info.DirectoryPath & "/config.dll", "Service Information", "Password")
serverName = readFromIni(My.Application.Info.DirectoryPath & "/config.dll", "Service Information", "userID")
serverDataBase = readFromIni(My.Application.Info.DirectoryPath & "/config.dll", "Service Information", "DataBaseName")
If serverID <> "" Then
connectionSqlString = "server =" + serverUrl + ";Database=" + serverDataBase + ";uid =" + serverName + ";pwd=" + serverID + ";max pool size=500"
Else
connectionSqlString = "server =" & serverUrl & ";integrated security = SSPI ;database = " & serverDataBase & ""
End If
conSql = New SqlConnection(connectionSqlString)
objCommand.Connection = conSql
Catch ex As Exception
MsgBox(ex.Message)
End Try
End Sub


'數據操作執行
Public Sub getConn(ByVal SqlStr As String, ByVal TableName As String)
Try
objCommand.CommandText = SqlStr
objDataSet.Clear()
objDataAdapter.SelectCommand = objCommand
objDataAdapter.Fill(objDataSet, TableName)
Catch ex As Exception
errNo = 1
MsgBox(ex.Message)
End Try
End Sub
'數據更新
Public Sub updateTable(ByVal StrSql As String)
objCommand.CommandText = StrSql
Try
conSql.Open()
Trans = conSql.BeginTransaction
objCommand.Transaction = Trans
objCommand.ExecuteNonQuery()
Trans.Commit()
Catch ese As Exception
MsgBox(ese.Message)
Trans.Rollback() '如果更新異常則取消所有更新
Finally
conSql.Close() '關閉連接
End Try
End Sub
