For AutoCAD 2007, this should do it:
/// Form1.cs
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using System.Runtime.InteropServices;
using Autodesk.AutoCAD.Runtime;
using Autodesk.AutoCAD.ApplicationServices;
using AcadApp = Autodesk.AutoCAD.ApplicationServices.Application;
// This form requires a PictureBox named 'pictureBox1':
namespace ThumbnailSample
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
// R17 ONLY
[DllImport( "acad.exe", CallingConvention = CallingConvention.Cdecl,
EntryPoint = "?acedGenerateThumbnailBitmap@@YAPAUtagABITMAPINFO@@XZ" )]
private static extern IntPtr acedGenerateThumbnailBitmap();
private void ThumbView_Load( object sender, EventArgs e )
{
IntPtr bmi = acedGenerateThumbnailBitmap();
if( bmi != IntPtr.Zero )
{
Bitmap bm = Marshaler.BitmapInfoToBitmap( bmi );
pictureBox1.Image = (System.Drawing.Image) bm.Clone();
bm.Dispose();
}
}
[CommandMethod( "THUMBVIEW" )]
public static void doit()
{
using( Form1 form = new Form1() )
AcadApp.ShowModalDialog( form );
}
}
}
