ObjectDBX技术: 脱离AutoCAD处理dwg文件(NET 实现)

以下均为console application，在vs2005中编译通过！需要引用Autodesk的Object DBX 或最新的Real DWG 的SDK。
如有其他的问题，请留言！
列举dwg文件中的所有的blcok的name:
C#实现:
using System;
using System.Collections;
using System.Collections.Generic;
using System.Text;
using System.Diagnostics;
using System.Reflection;
using System.Runtime;
using System.Windows.Forms;
using System.IO;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using Autodesk.AutoCAD.DatabaseServices;
using System.Runtime.InteropServices;
using Autodesk.AutoCAD.Runtime;
using Autodesk.AutoCAD.Geometry;
[assembly: SecuredApplication(
@"license")]
namespace GetFrameOfRealDwg
{
class MyHostApplicationServices : Autodesk.AutoCAD.DatabaseServices.HostApplicationServices
{
public override System.String FindFile(System.String fileName,
Autodesk.AutoCAD.DatabaseServices.Database database,
Autodesk.AutoCAD.DatabaseServices.FindFileHint hint
)
{
return string.Empty;
}
static public ArrayList GetBlockNames(Database db)
{
ArrayList array = new ArrayList();
Transaction tran = db.TransactionManager.StartTransaction();
try
{
BlockTable bt = (BlockTable)tran.GetObject(db.BlockTableId, OpenMode.ForWrite);
foreach (ObjectId recordid in bt)
{
17246
BlockTableRecord record = (BlockTableRecord)tran.GetObject(recordid, OpenMode.ForRead);
array.Add(record.Name);
}
}
catch
{
}
finally
{
tran.Dispose();
}
return array;
}
static void Main(string[] args)
{
MyHostApplicationServices myserver = new MyHostApplicationServices();
int lcid = 0x00001033; // English
RuntimeSystem.Initialize(myserver, lcid);
Database Db = new Database(false, true);
Db.ReadDwgFile(@"filepath", FileShare.Read, false, "");
ArrayList ar = GetBlockNames(Db);
foreach (string str in ar)
{
System.Console.WriteLine(str);
}
RuntimeSystem.Terminate();
System.Console.WriteLine();
}
}
}
注意: 只需ref :acdbmgd.dll
必须实现HostApplicationServices及她的findfile().
生成的dll必须使用绑定工具绑定.
(license是很贵的啊,可以到autodesk公司主页)

# re: ObjectDBX技术: 脱离AutoCAD处理dwg文件(NET
我按你的方法做了,可到acdbSetHostApplicationServices(&gCreatentHostApp);就报“DBX CAS 4”的错误，如何解决?

^_^！
你用的是c＋＋的吗,你可能是由于连接了一些多余的跟AUTOCAD平台有关的DLL。
如果你用的是c＃版的，你肯能是由于没有lience或是没有绑定成功，也可能是acdbmgd.dll的版本不正确！
^_^！
最后提醒这里说的Object DBX 不是Object ARX中的自定义实体啊，是Autodesk的另一个可以脱离autocad平台处理dwg的技术，最新的版本名字是RealDWG。
希望能够帮助大家！ 回复 更多评论

# re: ObjectDBX技术: 脱离AutoCAD处理dwg文件(NET 实现)2012-01-05
我建立了一个DBX项目,写了一个自定义实体,想以外部图纸作为模板画这个实体.
用到readDwgFile函数时总是不成功,出现DBX CAS4错误.
看到你的文章中说要实现AcDbHostApplicationServices,请问能再说的具体点吗? 回复 更多评论
