刪除windows上執行文件ce

Question

我想在windows ce上創建一個卸載程序。

問題是我想要在執行其他所有操作後刪除卸載程序本身。

這是可能以某種方式？還是有另一種方式來以另一種方式使一個unistaller？

你可以讓應用程序自己移動到回收站。這是一個痛苦，因爲你必須通過P/Invoke來完成這一切，並且有一個非直觀的結構。這個樣本應該可以幫到你。

 private bool Recycle(string path) 
    { 
     try 
     { 
      ShowProgress(string.Format("Moving {0} to Recycle bin.", path)); 
      SHFILEOPSTRUCT sfo = new SHFILEOPSTRUCT(); 
      sfo.hwnd = IntPtr.Zero; 
      sfo.wFunc = FO_DELETE; 
      sfo.fFlags = FOF_ALLOWUNDO | FOF_NOCONFIRMATION; 
      sfo.pFrom = path +'\0' + '\0'; 
      sfo.pTo = null; 
      sfo.fAnyOperationsAborted = false; 
      sfo.hNameMappings = IntPtr.Zero; 
      sfo.lpszProgressTitle = string.Empty; 
      int ret = SHFileOperation(ref sfo); 

      return (ret == 0); 
     } 
     catch (Exception ex) 
     { 
      ShowProgress(string.Format("Failed to move {0} to Recycle bin.", path)); 
      ShowProgress(ex.ToString()); 
     } 
     return false; 
    } 


    // SHFileOperation wFunc and wFunc values 
    public const uint FO_MOVE = 0x0001; 
    public const uint FO_COPY = 0x0002;

    public const ushort FOF_RENAMEONCOLLISION = 0x0008; 
    public const ushort FOF_NOCONFIRMATION = 0x0010; // Don't prompt the user. 
    public const ushort FOF_WANTMAPPINGHANDLE = 0x0020;// Fill in SHFILEOPSTRUCT.hNameMappings 
                // Must be freed using SHFreeNameMappings 
    public const ushort FOF_ALLOWUNDO = 0x0040; 
    public const ushort FOF_FILESONLY = 0x0080; // on *.*, do only files 
    public const ushort FOF_SIMPLEPROGRESS = 0x0100; // means don't show names of files 
    public const ushort FOF_NOCONFIRMMKDIR = 0x0200; // don't confirm making any needed dirs 
    public const ushort FOF_NOERRORUI = 0x0400; // don't put up error UI 
    public const ushort FOF_NOCOPYSECURITYATTRIBS = 0x0800; // dont copy NT file Security Attributes 
    public const ushort FOF_NORECURSION = 0x1000; // don't recurse ushorto directories. 

    //[StructLayout(LayoutKind.Sequential, CharSet=CharSet.Unicode)] 
    //If you use the above you may encounter an invalid memory access exception (when using ANSI 
    //or see nothing (when using unicode) when you use FOF_SIMPLEPROGRESS flag. 
    [StructLayout(LayoutKind.Sequential, CharSet = CharSet.Unicode)] 
    public struct SHFILEOPSTRUCT 
    { 
     public IntPtr hwnd; 
     public uint wFunc; 
     [MarshalAs(UnmanagedType.LPWStr)] 
     public string pFrom; 
     [MarshalAs(UnmanagedType.LPWStr)] 
     public string pTo; 
     public ushort fFlags; 
     [MarshalAs(UnmanagedType.Bool)] 
     public bool fAnyOperationsAborted; 
     public IntPtr hNameMappings; 
     [MarshalAs(UnmanagedType.LPWStr)] 
     public string lpszProgressTitle; 
    } 

    [DllImport("ceshell.dll")] 
    public static extern int SHFileOperation([In] ref SHFILEOPSTRUCT lpFileOp);

killer.cmd：

:a 
del uninstaller.exe 
if exist uninstaller.exe goto a 
del killer.cmd 

exitting您的卸載程序之前啓動它，所以uninstaller.exe將盡快，因爲它是有可能去掉，然後killer.cmd也將被刪除。

//雖然不知道CE中是否有.cmds，
