c#如何激活CAD窗口（红色部分如何写）

yangxi

           AutoCAD.AcadSelectionSet sset;
           AutoCAD.AcadApplication app;
           app = (AcadApplication)       

           System.Runtime.InteropServices.Marshal.GetActiveObject("AutoCAD.Application.16");
            short[] f1 = new short[] { 2 };
            object[] f2 = new object[] { "gtmodel" };
           
            sset=app.ActiveDocument.SelectionSets.Add("MySelect");

            this.Hide();

            //此次如何激活CAD窗口，让程序在cad中选择
           
            app.ActiveDocument.Utility.Prompt("请选择对象：");
            sset.SelectOnScreen(f1, f2);

            this.Show();

不知老兄是否解决问题了？我的方法比较复杂，就是模拟鼠标在CAD屏幕上点击一下。 

using System.Diagnostics;

加上

[DllImport("User32")]
        public extern static void mouse_event(int dwFlags, int dx, int dy, int dwData, IntPtr dwExtraInfo);

        [DllImport("User32")]
        public extern static void SetCursorPos(int x, int y);

        [DllImport("User32")]
        public extern static bool GetCursorPos(out POINT p);

        [DllImport("User32")]
        public extern static int ShowCursor(bool bShow);

        public struct POINT
        {
            public int X;
            public int Y;
        }

        [Flags]
        public enum MouseEventFlags
        {
            Move = 0x0001,
            LeftDown = 0x0002,
            LeftUp = 0x0004,
            RightDown = 0x0008,
            RightUp = 0x0010,
            MiddleDown = 0x0020,
            MiddleUp = 0x0040,
            Wheel = 0x0800,
            Absolute = 0x8000
        }

//==========================================模拟鼠标左键点击

        private void AutoMouseLeftClick(int x,int y)
        {

            int dx = 0;
            int dy = 0;
            mouse_event((int)(MouseEventFlags.LeftDown | MouseEventFlags.Absolute), dx, dy, 0, IntPtr.Zero);
            mouse_event((int)(MouseEventFlags.LeftUp | MouseEventFlags.Absolute), dx, dy, 0, IntPtr.Zero);
       
         
        }

模拟鼠标在屏幕 0,0坐标点击一下

AutoMouseLeftClick(0, 0);

请问blessli：

在CAD下显示一个无模式对话框，当鼠标离开该窗口后，如何将焦点转移至CAD主窗口？

你好，用AutoMouseLeftClick(0, 0);   的话，会出现"内部错误:  gedit 3"这种错误。是为什么呢？
