VB 修改窗体代码请求指正 俺是新手
'修改按钮
Private Sub cmdModify_Click()
strUserManage = UserManage(2)
If strUserManage = "ReadOnly" Then
MsgBox "对不起，你是只读用户不能修改记录，请与管理员联系！", vbInformation + vbOKOnly, " 警告"
Exit Sub
End If
'声明ADODB.Recordset对象变量
Dim rs As ADODB.Recordset
strSQL = "select * from documents where 学号='" & flgDocData.Columns(0) & "'"
'strSQL = "select * from documents where 学号='" & trvDocument.SelectedItem & "'"
Set rs = ExecuteSQL(Trim(strSQL))
Set Me.flgDocData.DataSource = rs
If rs.RecordCount > 0 Then

'显示班级修改界面
blnModifyDoc = True
frmDocModify.Show
frmDocModify.ZOrder 0

MsgBox "你还没有选择记录！", vbOKOnly + vbExclamation, "警告"
