進出口新的Visual Basic中「找不到可安裝的ISAM」的錯誤。我想問一下關於如何解決了這一問題「找不到可安裝ISAM。」我用Visual Basic作爲編程語言。我使用MS訪問作爲數據庫。我的程序是從訪問中獲取數據。這將是我的代碼。在VB.NET
Imports System.Data.OleDb
Module Main
Dim mDataPath As String
Sub Main()
GetPupils()
Console.ReadLine()
End Sub
Private Function GetConnection() As OleDb.OleDbConnection
'return a new connection to the database5
Return New OleDb.OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;" _
& "Database Password=oNer00FooR3n0 " & "Data Source=" & "C:\Users\ERICO YAN\Desktop\MSaccessDB\MSaccessDB\oneroofccp.mdb")
End Function
Public Function GetPupils() As DataSet
Dim conn As OleDb.OleDbConnection = GetConnection()
Try
Dim ds As New DataSet 'temporary storage
Dim sql As String = "select * from SESSIONS" 'query
Dim da As OleDb.OleDbDataAdapter = New OleDb.OleDbDataAdapter(sql, conn) 'connection
Try
da.Fill(ds, "SESSIONS") 'fetch data from db
Finally
da.Dispose() 'in case something goes wrong
End Try
Dim startVal = 0 'first record
Dim endVal = ds.Tables(0).Rows.Count 'total number records
For var = startVal To endVal - 1 'display records
Console.WriteLine(ds.Tables(0).Rows(var).Item(0).ToString() + " " + ds.Tables(0).Rows(var).Item(1).ToString() + " " + ds.Tables(0).Rows(var).Item(3).ToString() + " " + ds.Tables(0).Rows(var).Item(3).ToString()) 'code for display id and name
Next
Return ds
Finally
conn.Close()
conn.Dispose()
End Try
End Function
End Module
我想知道什麼是錯誤的原因,這樣我可以繼續我的節目..謝謝你這麼多的反饋..
太感謝你了.. @Alex K. –
