Multiple acdbmgd & acmgd references?

Anonymous — Mon, 19 Jan 2009 21:54:41 GMT

Is it possible to reference more than one version of these files in a
single project?

The reason I ask is that the 2 version of AutoCAD we are using have
different "properties" for the objects in question (the names change)...

No, you can't do that.

What properties are changed?

The textstyle property of the text object changed from "textstyle" to
"textstyleid"...

The only option would be to use reflection.

The class below defines two extension methods for
DBText and MText that can be used in either release:

You use them just like they were methods of the
DBText and MText objects:

ObjectId GetTextStyleId();

void SetTextStyleId( ObjectId value );

[code]



{code}



public static class VersionCompatibleExtensionMethods

{

   public static ObjectId GetTextStyleId( this DBText instance )

   {

      if( textStyleProperty != null )

         return (ObjectId) textStyleProperty.GetValue( instance, null );

      else

         throw new MissingMemberException();

   }



   public static ObjectId GetTextStyleId( this MText instance )

   {

      if( mtextStyleProperty != null )

         return (ObjectId) mtextStyleProperty.GetValue( instance, null );

      else

         throw new MissingMemberException();

   }



   public static void SetTextStyleId( this DBText instance, ObjectId value )

   {

      if( textStyleProperty != null )

         textStyleProperty.SetValue( instance, value, null );

      else

         throw new MissingMemberException();

   }



   public static void SetTextStyleId( this MText instance, ObjectId value )

   {

      if( mtextStyleProperty != null )

         mtextStyleProperty.SetValue( instance, value, null );

      else

         throw new MissingMemberException();

   }



   static VersionCompatibleExtensionMethods()

   {

      textStyleProperty = typeof( DBText ).GetProperty( "TextStyle" );

      if( textStyleProperty == null )

         textStyleProperty = typeof( DBText ).GetProperty( "TextStyleId" );

      mtextStyleProperty = typeof( DBText ).GetProperty( "TextStyle" );

      if( mtextStyleProperty == null )

         mtextStyleProperty = typeof( DBText ).GetProperty( "TextStyleId" );

   }



   private static PropertyInfo textStyleProperty = null;

   private static PropertyInfo mtextStyleProperty = null;

If you are using VB on VS2005 and need to support 2007 then this appears
to work.

If AcdApp.Version = 17.0 Then
CallByName(AddEnt, "TextStyle", CallType.Set, StyRec.ObjectId)
Else
CallByName(AddEnt, "TextStyleId", CallType.Set, StyRec.ObjectId)
End If

Rather than branching once when the code loads, your so-called
solution branches every single time the property's value is needed.

Astounding.

For those that use VS2005, you can still use the code posted
as extension methods, by just converting them to plain old
static methods (non-extension methods), and passing the
DBText or MText objects to them as the first parameter. Just
remove the 'this' from first parameter declaration.

good thinking on using extension methods for version compatibility...

I've been using the #if conditional directive, and then build with different constants defined, according to versions... Works too, but I like this solution a lot more!

Time to review some of my code 🙂

The example was when I first discovered the alternative, and was not
intended to be optimized. I later changed it to preset the string
variable on loading to avoid the branches.

CallByName(AddEnt, StyPrp, CallType.Set, StyRec.ObjectId)

What is "astounding" is that it took you almost 24 hours to criticize.

Nothing astounding about that, it's a side-effect of being busy.

Duh.

It still isn't 'optimized'.

Perhaps if you better understood the API you're using, you might understand
why there is a difference between caching a property name in a string, and
caching the PropertyInfo object returned by the reflection search for the
name.

Unfortunately I have other things things to do and can't really afford to
take the time to tutor you in the finer points of using reflection or
late-binding overhead, but feel free to visit the Microsoft newsgroups and
ask them to tell you more about it.

Hi. can you explain how to use you code in VS2010 express? (If i can.) I have many acad version 2009, 2010 and 2012

I dont know how to manage all this version... I want build only one DDL (if i can).

I dont know how to manage VS2010 exp for not check a part of my code.

My think :

Try

'v autocad 2010

DBTexte.TextStyleID =....

catch ex as exception

'v autocad 2009

DBTexte.TextStyle = ...

end try.

if a build with dll from autocad 2009 i have error for .TextStyleId and for autocad 2010 .textStyle

so ....

Thx
