VB利用DataGrid控件显示数据库中数据信息,DataGrid在数据库数据显示的时候非常重要,它在用户操作舒适度及数据排列方面有独到之处,对于Vb数据库编程的用户来说,掌握DataGrid的使用是至关重要的事情。
参考实例如下:
Public cnn As adodb.Connection
Public rst As adodb.Recordset
Public Sub setdb()
Set cnn = New adodb.Connection
cnn.Provider = "Microsoft.Jet.OLEDB.4.O"
cnn.ConnectionString = "Data Source=" & App.Path & "\personal.mdb;"
cnn.CursorLocation = adUseClient
cnn.Open
End Sub
Private Sub Form_Load()
On Error Resume Next
Dim Strsql As String
setdb
Set DataGrid1.DataSource = Nothing
Strsql = "select * from 备忘录 order by 编号"
Set rst = cnn.Execute(Strsql)
If Err Then
MsgBox "读取数据失败"
Exit Sub
End If
If rst.EOF Then
Set DataGrid1.DataSource = Nothing
Else
Set DataGrid1.DataSource = rst
End If
End Sub
参考实例如下:
Public cnn As adodb.Connection
Public rst As adodb.Recordset
Public Sub setdb()
Set cnn = New adodb.Connection
cnn.Provider = "Microsoft.Jet.OLEDB.4.O"
cnn.ConnectionString = "Data Source=" & App.Path & "\personal.mdb;"
cnn.CursorLocation = adUseClient
cnn.Open
End Sub
Private Sub Form_Load()
On Error Resume Next
Dim Strsql As String
setdb
Set DataGrid1.DataSource = Nothing
Strsql = "select * from 备忘录 order by 编号"
Set rst = cnn.Execute(Strsql)
If Err Then
MsgBox "读取数据失败"
Exit Sub
End If
If rst.EOF Then
Set DataGrid1.DataSource = Nothing
Else
Set DataGrid1.DataSource = rst
End If
End Sub

Dim cn As New ADODB.Connection
Dim Adodc As New ADODB.Recordset
Private Sub Form_Load()
cn.Open = "provider=Microsoft.jet.OLEDB.4.0;Persist security info= False; Data source= " & App.Path & "\ 图书馆查询管理系统.mdb"
Adodc.CursorLocation = adUseClient
Adodc.Open "select * from readerinfo", cn, adOpenStatic, adLockOptimistic
Set DataGrid1.DataSource = Adodc
End Sub
试试 ,,不行的话,HI我
