Topic: Bricscad && .NET

[MickD]

I'm pretty keen to work with Bricscad but without the hlr engine (the engine used for SOLPROF etc) it is a big draw back for what I need to do.
As soon as they implement that and have the .net api I'll be there in a flash

Update: I posted a version compiled with  .NET 4 (Release), see the first post in this thread.

Daniel   I get this warning in C# Express.

Warning   1   A reference was created to embedded interop assembly 'c:\Program Files\RxNet\V10\Interop.BricscadDb.10.0.dll' because of an indirect reference to that assembly created by assembly 'c:\Program Files\RxNet\V10\RxNet.dll'. Consider changing the 'Embed Interop Types' property on either assembly.   

Since I am ignorant as to compiler reference jargon I was wondering if I should do as recommended to RxNet by setting to True or the Interops to false? Just figured you'd know off the top of your head.

... you can remove the references to the DLLs I provided and add your own though the com tab.. use the default settings

Was looking thru some of your samples in NativeMethods.cs in RxNetSamples and have a question.  I see you are now using dllimport of "brx10.dll" rather than "bricscad.exe".  I could not get C# express to find the file, whereas bricscad.exe - no problem.  I was just invoking grdraw as it appears missing in com.  Did you go to brx10.dll because the future of calling sds_grdraw (for instance) may go away in the future? or ..  The function would be acedGrDraw in brx10.dll. 

Do I need to copy brx10.dll to the C# project folder?  Was going to be invoking grread as well, but even in lisp the function is unclear to me.  Is there a buffer that needs to be flushed when tracking coords?  or it just taking a snapshot and assigning to my varriable? 

The routine I'm playing with is to read objects Z value on mouse over and indicate %Grade from some given point.  Used it for "pioneering" roadway layout and found it handy.

if it's a BRX  function you would p/invoke from BRX10.dll, if it's a SDS function p/invoke from Bricscad.exe. I don't think the SDS version will go away anytime soon.
 Let me see what it will take to wrap these functions for you, grread might be a little difficult.

Hi Jerry,

I've updated install attached to the first post in this thread..

heres a sample

Code: [Select]

using System;
//
using BricscadApp;
using BricscadDb;
using RxNet.ApplicationServices;
using RxNet.Runtime;
using RxNet.RxGlobal;
using RxNet.Geometry;
using RxNet.DatabaseServices;
using RxNet.Editor;


namespace Bricscad
{
  public static class Commands
  {
    [CommandMethod("doit")]
    public static void test01()
    {
      var app = Application.AcadApplication as AcadApplication;
      var doc = app.ActiveDocument;
      try
      {
        bool doloop = true;
        Point3d last = Point3d.kOrigin;
        while (doloop)
        {
          GrReadResult res = GlobalFunctions.GrRead(1);
          if (res.Buffer.TypeCode == (short)LispDataType.Point3d)
          {
            Point3d next = (Point3d)res.Buffer.Value;
            GlobalFunctions.GrDraw(last, next, 6, 0);
            last = next;
          }
          //doc.Utility.Prompt(String.Format("\n{0},{1}", res.AnswerType , res.Buffer));
          if (res.Status == PromptStatus.Cancel)
            doloop = false;
        }
      }
      catch (System.Exception ex)
      {
        doc.Utility.Prompt(String.Format("\n{0}", ex.Message));
      }
    }
  }
}

Hi Dan, any chance of updating the 1.010 version as well?  I am using Delphi prism for my .NET fun and don't have access to the V4 framework. Can't wait till Bricsys support a full .NET implementation but in the mean time your libraries make things far more accessible than COM alone can.  I've said it before but great work!

Hi Dan, any chance of updating the 1.010 version as well? 

Yep, I will post it in a couple of hours 

[It's Alive!]

Hey Daniel,

I've posted it, let me know of you run into any issues.

[Daniel Eiszele]

Thanks Dan, are you operating out of the Tardis?  That couple of hours only seemed like 20 minutes 

[Jerry J]

Thanks a bunch!

Still wondering why I could p\invoke "bricscad.exe" but said it coun't find "brx10.dll"? So I ran dependency walker which came up with all sorts of can't finds on brx10.dll and just two on bricscad.exe.  A couple of the missing dependencies were MFC and ATL which don't come in the express versions so maybe thats why?  Just curious, since I would think that brx10.dll was already loaded by the time I netload my app.

Anyway this will be fun.  Now I can play with all that cool grread stuff that Andrea is doing in lisp.

Hi Dan, is there any chance you converted the 1.01-2 version to Net 4 as well?  I have tried referencing it but it wont load as VS tells me it's created with a newer runtime than I have loaded.  I believe I am using 3.5; but I am new to the .Net thing and I might be doing something else incorrectly?

Hard to say without seeing the code, it could be that you had a bad entry point or the signature was invalid.
It's really easy for me to add these in, just holler if you need something else
