老师，麻烦看看这个内部函数，登录后执行，可见，可用没有根据集合转换到用户管理的可见、可用列里面呢。   

    User_Control.clear
    User_Control.AddRange(dr("菜单可用集合").Split(",")) \'权限集合
    User_Control1.clear
    User_Control1.AddRange(dr("菜单可见集合").Split(",")) \'权限集合
    Functions.Execute("Design_Add")

内部函数：集合转授权表

老师，图片问题这样解决字母处理，把彩色转成黑白，论坛上这样写的：

我现在这个把不可用字母转成黑白：

Dim pag As WinForm.TabControl = Forms("主窗口").Controls("tabControl2")
Dim dru As DataRow = DataTables("用户管理").SQLFind("账号=\'" & _UserName & "\'")
If dru Is Nothing Then : Return 0 : End If
Dim kjjhs() As String = dru("菜单可见集合").Split(",")
Dim kyjhs() As String = dru("菜单可用集合").Split(",")
For Each fl As String In DataTables("导航").GetValues("分类","[分类]<> \'"& pag.SelectedPage.Name & "\'","序号") \'增加分类
    If Array.IndexOf(kjjhs,fl) = -1 Then \'跳过不可见的页面插入
        Continue For
    End If
    If pag.TabPages(fl) Is Nothing Then
        Dim pc As object = pag.TabPages.Add(fl,fl)  \'新增加页签
        Dim dr As DataRow = DataTables("导航").Find("分类 = \'" & fl & "\'")
        If dr IsNot Nothing Then
            pc.Image= GetImage(dr("分类图标"))  \'增加页签图标
        End If
    End If
Next
Dim lvw As WinForm.ListView = forms("主窗口").Controls("ListView1")
lvw.StopRedraw() \'停止绘制
lvw.Groups.Clear() \'清除原来的分组
lvw.Columns.Clear() \'清除原来的列
lvw.Rows.Clear() \'清除原来的行
lvw.Images.Clear() \'清除原来的图片
lvw.View = ViewMode.Details \'显示模式为详细信息
lvw.TitleSize = New Size(130,80) \'设置平铺区域大小
lvw.GridLines  = True \'显示网格线
Dim cls() As String = {"名称"} \'定义列名
Dim wds() As Integer = {100} \'定义列宽
For i As Integer = 0 To  cls.Length - 1  \'增加列
    Dim c As WinForm.ListViewColumn = lvw.Columns.Add()
    c.Name = cls(i) \'指定列名
    c.Text = cls(i) \'指定标题,这里标题和列名相同
    c.Width = wds(i) \'指定列宽
Next
Dim drs As List(of DataRow )= DataTables("导航").Select ("[分类] = \'"& pag.SelectedPage.Name & "\'","序号") \'增加分组
For Each dr As DataRow In drs
    If array.IndexOf(kjjhs,dr("名称")) = -1 Then \'不可见的跳过
        Continue For
    End If
    If lvw.Groups.contains(dr("分组")) =False Then
        Dim grp As WinForm.ListViewGroup = lvw.Groups.Add()
        grp.Name = dr("分组")
        grp.Text = dr("分组")
    End If
    Dim r As  WinForm.ListViewRow =  lvw.Rows.Add() \'增加一行
    Dim key As String= dr("图标")
    lvw.Images.AddImage(Key, Key, Key) \'添加代表这个名称的一对图标
    r.ImageKey = Key \'指定图标键值
    r.Group = dr("分组") \'指定所属分组
    r.Tag = dr
    For Each cl As String In cls \'逐列取值
        r(cl) = dr(cl)
    Next
    If array.IndexOf(kyjhs,dr("名称")) = -1 Then \'不可用的着色
        r.ForeColor= Color.Red
    End If
    lvw.ResumeRedraw() \'恢复绘制
    lvw.View = ViewMode.LargeIcon \'显示模式切换为大图标
Next
