Database.UpdateExt() Exception

[MattKincaid]

For a particular DWG file, I'm getting a System.AccessViolationException when calling Database.UpdateExt(False).  Interestingly, if I change to UpdateExt(True), no exception occurs.  Oddly, Try...Catch doesn't seem to catch the exception with UpdateExt(False).

Any ideas about what the problem is?  The DWG file seems pretty basic (2D, with reasonable extents). 

Thanks!

Hi,

Can you please share the drawing?

Does it have custom entities ?

You can download the DWG from the link below.

I didn't create the file, so I'm not sure whether there are custom entities or not.  Thanks!

Thanks Alex, do the problem resolves after recovering the drawing?

[Alexander.Rivilis]

I've not problem both original and recovered dwg-file with AutoCAD 2020.1.2

Sample code:

static void ADSKMyGroupMyCommand() {
  // Put your command code here
  acdbCurDwg()->updateExt(false);
  acdbCurDwg()->updateExt(true);
}

 dwg

Thanks for looking into it.  I had tried Audit as well, but fixing the file errors does not solve the problem for me. 

I just realized I'm using an older version of acdmmgd.dll (v 22.0.50.0.0).  Perhaps updating will fix for me?  I'll give it a shot and send an update with my results.

Your question was posted to wrong forum as far as you do not use ObjectARX, but use AutoCAD .NET API. I did not checked with AutoCAD .NET API, but you have to use acdbmgd.dll from AutoCAD.

[MattKincaid]

@Alexander.RivilisI'm using RealDWG 2018 to develop a stand alone application. 

My understanding was that RealDWG and ObjectARX were the same thing, and that AutoCAD .NET API was for coding AutoCAD addins.  Is that understanding not correct?

RealDWG also has native C++ and managed .NET libraries. AutoCAD .NET API and RealDWG .NET API are closer together than ObjectARX and AutoCAD .NET API. ObjectARX != RealDWG

[MattKincaid]

@Alexander.RivilisAh.  Could you please advise which forum is most appropriate?

P.S.: But you have to specify that you use not AutoCAD .NET API but RealDWG (.NET)
