带有历史记录功能的菜单
1、 1.打开vb,选择标准窗口，在工具菜单里选择编辑菜单器，各项设置如下：
caption name index
visible indentation
file mnufile 空 true 0
Open mnuopen 空 true 1
- mnudesh 空 true 1
空 mnufilename 1 false 1
空 mnufilename 2 false 1
空 mnufilename 3 false 1
空 mnufilename 4 false 1
空 mnufilename 5 false 1
abc mnufilename 6 false 1
2、---- （注：一定要在最后一项的caption设一虚值,这样做的原因是为了后面在菜单项未满时添加文件名做判断,并没有实际意义)
---- 2.在窗体中加载一对话框,对话框的name为commongdialog1
---- 3.源程序如下:
---- 在通用里声明:
Const k1 = "记忆菜单"
Const k2 = "文件名"
Function addfilename(filename)'添加文件名
DIM I,G AS INTEGER
3、For I = 5 To 1 Step -1'从第五项开始向第一项
If mnufilename(1).Caption < > filename And
mnufilename(2).Caption < > filename
And mnufilename(3).Caption < > filename And
mnufilename(4).Caption < > filename
And mnufilename(5).Caption < > filename
Then '判断所选的文件是否已存在
If mnufilename(I).Caption = "" And
mnufilename(I + 1).Caption < > ""
Then '此处初使化菜单，利用了虚设菜单项
SaveSetting k1, k2, I, filename'在注册表里保存
Else
4、If mnufilename(1).Caption < > ""
Then '表明菜单已满
DeleteSetting k1, k2, 5
'按先入先出规则,删除最后一项
For G = 4 To 1 Step -1 '一至四项依次后移
n = GetSetting(k1, k2, G)'从注册表里取其值
SaveSetting k1, k2, (G + 1), n'顺延到下一项
Next
SaveSetting k1, k2, 1, filename
Exit Function
End If
End If
End If
5、Next
End Function
Function display()'显现各项文件名
DIM I AS INTEGER
For I = 5 To 1 Step -1
l = GetSetting(k1, k2, I)
If l < > "" Then
mnufilename(I).Visible = True
mnufilename(I).Caption = l
Else
mnufilename(I).Visible = False
mnufilename(I).Caption = ""
End If
Next
6、End Function
Private Sub Form_Load()
Call display
End Sub
Private Sub mnuopen_Click()
7、DIM FILENAME
Commondialog1.ShowOpen
filename = Commondialog1.filename
Call addfilename(filename)
Call display
End Sub
