如何制作自动安装包？

[dangyaofei]

我向实现软自动更新，每次更新后，程序能自动安装，

软件有更新－＞启动更新软件，并关闭主软件－＞更新软件下载更新文件，下载完后替换文件或安装－＞启动主软件，并关闭更新软件

逻辑就这样，见1楼。
当中要自动安装，需要用到ShellExecuteEx，来安装你的cab.要是替换文件方式的话,用CreateProcess。

#region PInvoke defintions
		class SHELLEXECUTEEX
		{
			public UInt32 cbSize; 
			public UInt32 fMask; 
			public IntPtr hwnd; 
			public IntPtr lpVerb; 
			public IntPtr lpFile; 
			public IntPtr lpParameters; 
			public IntPtr lpDirectory; 
			public int nShow; 
			public IntPtr hInstApp; 

			// Optional members 
			public IntPtr lpIDList; 
			public IntPtr lpClass; 
			public IntPtr hkeyClass; 
			public UInt32 dwHotKey; 
			public IntPtr hIcon; 
			public IntPtr hProcess; 
		}

		[DllImport("coredll")]
		extern static int ShellExecuteEx( SHELLEXECUTEEX ex );

		[DllImport("coredll")]
		extern static IntPtr LocalAlloc( int flags, int size );

		[DllImport("coredll")]
		extern static void LocalFree( IntPtr ptr );

		[DllImport("coredll")]
		public static extern IntPtr GetCapture();

		[DllImport("coredll")]
		public static extern IntPtr MoveWindow(IntPtr hWnd, int X, int Y, int Width, int Height, bool Repaint);

		[DllImport("coredll")]
		public static extern int GetWindowLong(IntPtr hWnd, int nItem);

		[DllImport("coredll")]
		public static extern void SetWindowLong(IntPtr hWnd, int nItem, int nValue);
		
		public const int GWL_STYLE     =      (-16);
		public const int GWL_EXSTYLE   =      (-20);
		public const int GWL_USERDATA  =      (-21);
		public const int GWL_ID        =      (-12);

		public const int WS_BORDER     =      0x00800000;
		public const int WS_CAPTION     =     0x00C00000;

		#endregion

  [DllImport("coredll.Dll")]
        private static extern int CreateProcess(string strImageName, string strCmdLine, IntPtr pProcessAttributes, IntPtr pThreadAttributes, int bInheritsHandle, int dwCreationFlags, IntPtr pEnvironment, IntPtr pCurrentDir, Byte[] bArray, ProcessInfo oProc);
