WPF设计器启动进程

Question

我正在做一个direct3d12应用程序，我想为它编写一个编辑器。这个应用程序是C++，但是编辑器是用WPF完成的，我从WPF向进程发送HWND，然后进程创建到WindowsFormsHost面板的交换链。我在自定义控件构造函数中启动了该进程，由于某种奇怪的原因，该构造函数启动了锁定exe的进程。在真正运行WPF应用程序之前，如何停止设计器以运行该进程？

public partial class RenderWindow : UserControl
{
    Process AberrationEngine = new Process();
    public RenderWindow()
    {
        InitializeComponent();

    }

    private void UserControl_Unloaded(object sender, RoutedEventArgs e)
    {
        if (!AberrationEngine.HasExited)
        {
            AberrationEngine.Kill();
        }
    }

    private void UserControl_Loaded(object sender, RoutedEventArgs e)
    {
        IntPtr HWND = RenderWindowBase.Handle;

        AberrationEngine.StartInfo.FileName = @"C:\Users\nagylas\Desktop\AberrationEngineNextGen\x64\Release\AberrationEngine.exe";
        AberrationEngine.StartInfo.Arguments = "--editor --handle " + HWND.ToString();
        AberrationEngine.StartInfo.UseShellExecute = false;
        AberrationEngine.StartInfo.WorkingDirectory = @"C:\Users\nagylas\Desktop\AberrationEngineNextGen\AberrationEngine";
        AberrationEngine.Start();
    }
}

和XAML

Answer 1

您可能应该检查一下这是否是设计模式。您可以使用DesignerProperties.GetIsInDesignMode函数来完成此操作。

Documentation

所以，基本上是这样的：

if (!DesignerProperties.GetIsInDesignMode(this))
{
    //your code running the process
}
