【问题描述】：

我正在开发一个 Windows 移动应用程序。我创建了一个使用模式窗口的向导，以便隐藏窗口栏。其中一个向导阶段需要拍照。启动 CaptureCameraDialog 后，即使在 CaptureCameraDialog 关闭后，窗口栏也会出现并保留。有什么办法可以让我的对话框回到窗口栏的前面？

我最终设法在网络上找到了一些符合我要求的代码。这里是：

public partial class myForm : Form
{
public myForm()
{
   InitializeComponent();
        this.GotFocus += delegate(object sender, EventArgs args)
                             {
                                 //var intPtr = FindWindow("CaptureReturnForm", "");
                                 SetForegroundWindow(GetFocus());
                                 bool result = SHFullScreen(GetFocus(), SHFS_HIDESTARTICON |
                                 SHFS_HIDETASKBAR | SHFS_HIDESIPBUTTON); // 0x0020);

                             };


    }

    [DllImport("coredll.dll")]
    private static extern IntPtr FindWindow(string lpClassName, string lpWindowName);
    [DllImport("coredll.dll", EntryPoint = "SetForegroundWindow")]
    private static extern int SetForegroundWindow(IntPtr hWnd);
    [DllImport("coredll.dll")]
    internal static extern IntPtr GetFocus();
    [DllImport("aygshell.dll")]
    internal static extern bool SHFullScreen(IntPtr hWnd, uint dwState);

    const uint SHFS_SHOWTASKBAR = 0x1;
    const uint SHFS_HIDETASKBAR = 0x2;
    const uint SHFS_SHOWSIPBUTTON = 0x4;
    const uint SHFS_HIDESIPBUTTON = 0x8;
    const uint SHFS_SHOWSTARTICON = 0x10;
    const uint SHFS_HIDESTARTICON = 0x20;
    const int HWND_TOPMOST = -1;
    const int HWND_NOTOPMOST = -2;

    const uint SWP_SHOWWINDOW = 0x40;
    const uint SM_CXSCREEN = 0x0;
    const uint SM_CYSCREEN = 0x1;
    private const int HHTASKBARHEIGHT = 26;
}
