Topic: Use same code for acad and bcad, references are an issue

[jmaeding]

At the top, I have:
using Autodesk.AutoCAD.DatabaseServices;
using Autodesk.AutoCAD.EditorInput;
using Autodesk.AutoCAD.Geometry;
using Autodesk.AutoCAD.Runtime;

and so on.
I want to use Bricscad in place of the Autodesk.AutoCAD, but the only way I know is to change the text.
Not only that, but I am getting tired of maintaining several sets of code for each acad version.
I make partial classes so each has a portion that has different code for each version.

I would like to get down to one set of code that uses conditional  symbols to decide what to run.
Can conditionals be used with using statements?

Hi,

Maybe you ca use 'conditional compilation'.

1. Create a Visual Studio project for AutoCAD referencing AutoCAD assemblies with, at the top of each file (class):

#if ACAD
using Autodesk.AutoCAD.DatabaseServices;
using Autodesk.AutoCAD.EditorInput;
using Autodesk.AutoCAD.Geometry;
using Autodesk.AutoCAD.Runtime;
#endif
using Bricscad.DatabaseServices;
using Bricscad.EditorInput;
using Bricscad.Geometry;
using Bricscad.Runtime;

2. Add to your project properties, in the  Build tab, the Conditional compilation symbol: ACAD

3. In the same solution, create a new project referencing Bricscad assemblies.

4. Right click on the Bricscad project in the solution explorer > Add > Existing element. Select all the files (classes) from the AutoCAD project folder and change the Add button in the bottom of the dialog to Add as Link.

5. Try to compile...

This way, every changes to the AutoCAD project code will affect the Bricscad project.

PS: I'm not certain about the Visual Studio UI translation.

wow, too easy. I did that and it seemed to work.
I had thought the #if only applied at compile time, so VS would be confused during coding.
Thanks a bunch!

And also you can use conditional compilation in other contexts. Example:

Code - C#: [Select]

1. #define EXTASIEXTATAMBIEN
2.  
3. using System;
4.  
5. namespace eskaralakakatua
6. {
7.     internal class Class1 :
8. #if ILOVEMEZCAL
9.     Mezcal
10. #elif ILOVETEQUILA
11.     Tequila
12. #else
13.     Vodka
14. #endif
15.     {
16.  
17. #if PRIVATE
18.         private
19. #else
20.         internal
21. #endif
22.         void zzzz()
23.         {
24. #if EXTASIEXTATAMBIEN
25.             // Rula 1
26. #else
27.             // Rula 2
28. #endif
29.         }
30.     }
31.  
32.     internal class Tequila
33.     {
34.     }
35.  
36.     internal class Mezcal
37.     {
38.     }
39.  
40.     internal class Vodka
41.     {
42.     }
43.  
44. }

I set up a project template and/or hand-edit the VS project file (it's XML). See http://www.theswamp.org/index.php?topic=41868.msg497509#msg497509 for more details, and that thread in general for other (perhaps better, less manual) ideas.
