你的变量名st0是在Command1_Click()里声明的,那么在Command2_Click()里如何能够识别?
修改如下:
Private st0 As New ADODB.Recordset '定义一个stordest对象
Private Sub Command1_Click() '查询
Dim cn As New ADODB.Connection '定义一个数据库对象
Dim sl As String
cn.Open "Provider=SQLOLEDB.1;Persist Security Info=False;User ID=sa;Initial Catalog=xiewei;Data Source=PC-20110605TMUI"
sl = "select * from xwuser "
st0.Open sl, cn, adOpenKeyset, adLockOptimistic
Set DataGrid1.DataSource = st0
End Sub
Private Sub Command2_Click() '删除
st0.Delete
DataGrid1.Refresh
End Sub
说明:删除记录并不需要
st0.Update
修改如下:
Private st0 As New ADODB.Recordset '定义一个stordest对象
Private Sub Command1_Click() '查询
Dim cn As New ADODB.Connection '定义一个数据库对象
Dim sl As String
cn.Open "Provider=SQLOLEDB.1;Persist Security Info=False;User ID=sa;Initial Catalog=xiewei;Data Source=PC-20110605TMUI"
sl = "select * from xwuser "
st0.Open sl, cn, adOpenKeyset, adLockOptimistic
Set DataGrid1.DataSource = st0
End Sub
Private Sub Command2_Click() '删除
st0.Delete
DataGrid1.Refresh
End Sub
说明:删除记录并不需要
st0.Update

If DataGrid1.ColIndex > -1 Then
DataGrid1.Bookmark
End If
DataGrid1.Bookmark
End If

注意这个DataGrid1.ColIndex
d=datagrid1.colindex
sl="select * from xwuser where xxx='" & datagrid1.TextMatrix(xx, 4) & "xxx='" & datagrid1.TextMatrix(xx, 3) & "'"
