Hi all,
 
I've found a code to open a dwg file in autocad with objectARX commands.this code works successfully when i wrote it in a Class Library project, but the problem is happened when i want to place this code in my windows application.It gives me this error message :

 

The type initializer for '< Module >' threw an exception.
 
Inner Exception : The C++ module failed to load during process initialization.

 

My code is :

 

String MyDWGFilePath = @"\\Server\SharedFolder\Projects\File1.dwg";
DocumentCollection dm = Application.DocumentManager;
Document doc = null;
 
if(File.Exists(MyDWGFilePath))
{
   doc = dm.Open(MyDWGFilePath, false);
   Application.DocumentManager.MdiActiveDocument = doc;
}

 Note: I've add acdbmgd.dll and acmgd.dll from autocad installed folder and also AutoCAD and AXDBLib from COM references.

 

please tell me what is my mistake???

Hi,

 

>> when i want to place this code in my windows application

Do you mean that you develop an external EXE (and not an internal DLL)? If so you have no access to the managed API (it's near to ObjectARX, but it's not ARX). The only option then is to work with COM.

Hi alfred,

 

Do you mean ObjectARX just works in DLLs but not in exe applications?

So how can i open a dwg file from a windows application?

please describe for me how can i use COM instead of ARX?

 

i'm too confused.please help me...

Hi,

ObjectARX works only within AutoCAD, plus ObjectARX is written in C++ so it's unmanged and it's not a DLL, it's a special kind of DLL with the extension ARX

If you do your coding with C# or VB.NET (or any dotNET based language) then you are using the managed API from AutoCAD and also this (DLL then) runs only inside of AutoCAD (either loaded with command _NETLOAD or some settings in the registry to get loaded autmatically).

 

If you control AutoCAD from an external EXE you can only use the COM/ActiveX way and that works in the same way as you control Excel, Word or any other COM-based API.

 

You can start it with

CreateObject("AutoCAD.Application")    'or also using the version-number if you have to start a specific release

or you can use the Processes to start another EXE like:

Processes.Start("ACAD.EXE")   'of course you will use the path to the exe here

and then GetObject(,"AutoCAD.Application")    'to get access to the AutoCAD ActiveX server

 

A lot of search samples could be found using Google with >>>CreateObject("AutoCAD.Application")<<<


HTH, - alfred -
