1.
a.将你的程序设为启动项:
用注册表操作函数在注册表HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run 下建立一个字符串值,修改值为你的程序运行路径b.在程序开始运行的代码里,使用API函数 SetWindowPos 使程序置前
以下是实例:
Const HWND_TOPMOST = -1
Const HWND_NOTOPMOST = -2
Const SWP_NOSIZE = &H1
Const SWP_NOMOVE = &H2
Const SWP_NOACTIVATE = &H10
Const SWP_SHOWWINDOW = &H40
Private Declare Sub SetWindowPos Lib "User32" (ByVal hWnd As Long, ByVal hWndInsertAfter As Long, ByVal X As Long, ByVal Y As Long, ByVal cx As Long, ByVal cy As Long, ByVal wFlags As Long)
Private Sub Form_Activate()
'Set the window position to topmost
SetWindowPos Me.hWnd, HWND_TOPMOST, 0, 0, 0, 0, SWP_NOACTIVATE Or SWP_SHOWWINDOW Or SWP_NOMOVE Or SWP_NOSIZE
End Sub2.修改文件的文件名:
最简单的方法: Shell "rename c:\1.txt 2.txt"

放到form_load 就可以了
