我正在使用 User32 的 ShowWindow 方法向用户隐藏一个窗口(cmd.exe)(主要是为了防止他们关闭它)。当用户打开表单时,进程启动并隐藏,然后当表单关闭时,进程被终止。但是,当再次打开表单时,它不会隐藏窗口(有时不是第一次)有人可以帮我解决这个问题吗?
    [DllImport("User32")]
    private static extern int ShowWindow(int hwnd, int nCmdShow);   //this will allow me to hide a window
    public ConsoleForm(Process p) {
        this.p = p;
        p.Start();
        ShowWindow((int)p.MainWindowHandle, 0);   //0 means to hide the window. See User32.ShowWindow documentation SW_HIDE
        this.inStream = p.StandardInput;
        this.outStream = p.StandardOutput;
        this.errorStream = p.StandardError;
        InitializeComponent();
        wr = new watcherReader(watchProc);
        wr.BeginInvoke(this.outStream, this.txtOut, null, null);
        wr.BeginInvoke(this.errorStream, this.txtOut2, null, null);
    }
    private delegate void watcherReader(StreamReader sr, RichTextBox rtb);
    private void watchProc(StreamReader sr, RichTextBox rtb) {
        string line = sr.ReadLine();
        while (line != null && !stop && !p.WaitForExit(0)) {
            //Console.WriteLine(line);
            line = stripColors(line);
            rtb.Text += line + "\n";
            line = sr.ReadLine();
        }
    }
    public void start(string[] folders, string serverPath) {
        this.inStream.WriteLine("chdir C:\\cygwin\\bin");
        //this.inStream.WriteLine("bash --login -i");
        this.inStream.WriteLine("");
    }
    private void ConsoleForm_FormClosed(object sender, FormClosedEventArgs e) {
        this.stop = true;
        try {
            this.p.Kill();
            this.p.CloseMainWindow();
        } catch (InvalidOperationException) {
            return;
        }
