主题：自定义用户登录的问题

自定义用户登录界面中：取消键的代码为e.Form.Close，点击之后就会以系统的默认用户登录，我的理解应该是推出登录，老大取消按钮的代码应该如何写

老大你在吗，请指点，我的项目就缺这一步了

e.form.clsoe

syscmd.project.exit

添加上syscmd.project.exit之后，提示上面的错误，请老大再看看

 

做简单例子上来

菜单我使用的是在系统菜单的基础之上略加修改，上面提示的部分也没有作任何修改

提示错误是发布后的项目

要不在AfterOpenproject中设置代码，如果用户单击的是取消按钮，就退出。

还有这样的提示：代码是

Forms("用户登录").Open()
'动态加载数据表
For Each dr As DataRow In DataTables("数据加载").DataRows
    Dim s As String = dr("数据库名")
    Dim s1 As String =dr("表名")
    If dr.IsNull("数据库名")=False Then
        If Connections(s).GetTableNames.Contains(s1) Then
            If dr("是否加载")=True Then
                Dim q As new OuterTableBuilder
                q.TableName = s1
                q.ConnectionName = s
                q.SelectString = "Select * From [" & s1 & "] "
                q.Build
            End If
        Else
            MessageBox.Show(s1 & " 外部表不存在,不能加载!")
        End If
    End If
Next
'动态创建关联表

    Tables(tb.Name).OpenView("默认视图")

Dim Code As String = GetConfigValue("Register" & ComputerId,"")

SaveConfigValue("Count",n)

 

这种应该如何设置，请老大指点以下
