Question

如何在VB运行中动态添加菜单项目？

Answer 1

方法1：使用菜单数组
在文件菜单里增加一个菜单项,标题任意,现在假设菜单项的Name属性是mnuDynamic
更改菜单项mnuDynamic的可见属性,使mnuDynamic.Visible= False
更改菜单项mnuDynamic的下标(索引)属性,使mnuDynamic.Index=0
在程序中控制菜单项mnuDynamic的动态装入。
Load mnuDynamic(1)
mnuDynamic(1).Caption = "动态菜单1"
mnuDynamic(1).Visible = True

方法2：使用用API函数
新建一个模块，复制以下代码。
Public Declare Function SetWindowLong Lib "user32" Alias "SetWindowLongA" (ByVal hwnd As Long, ByVal nIndex As Long, ByVal dwNewLong As Long) As Long
Public Declare Function CallWindowProc Lib "user32" Alias "CallWindowProcA" (ByVal lpPrevWndFunc As Long, ByVal hwnd As Long, ByVal Msg As Long, ByVal wParam As Long, ByVal lParam As Long) As Long
Public Const MF_STRING = &H0&
Public Const MF_BYCOMMAND = &H0&
Public Const GWL_WNDPROC = (-4)
Public Const WM_COMMAND = &H111
Public OldWinProc As Long

Public Function OnMenu(ByVal hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, ByVal lParam As Long) As Long
'{响应菜单事件}
If wMsg = WM_COMMAND Then
If wParam = 1000 Then MsgBox "Dynamic"
End If
OnMenu = CallWindowProc(OldWinProc, hwnd, wMsg, wParam, lParam)
End Function

窗体代码：
Private Sub Form_Load()
Dim hMenu As Long, hSubMenu As Long
hMenu = GetMenu(Me.hwnd)
hSubMenu = GetSubMenu(hMenu, 0)
InsertMenu hSubMenu, 0, MF_BYCOMMAND Or MF_STRING, 1000, "Dynamic"
OldWinProc = SetWindowLong(Me.hwnd, GWL_WNDPROC, AddressOf OnMenu)
End Sub

Answer 2

是不是这样？
System.Diagnostics.Process.Start("notepad")
这样呢？
大哥，你是想调用别人程序，还是自己的程序啊？
调用别人程序是要路径的啊？把路径写进去也行啊？
