RasterImageDef and GetReactor method

[Anonymous]

I think to get the information I want I have to use the GetReactor method on the RasterImageDef object. The problems is when I get the DBObjectCollection returned, it won't let me look at any of the objects within the collection. It errors out with
"Attempted to read or wirte protected menory. This is ofter an indication that other memory is corrupt."

What I'm trying to do is get the RasterImage object from the RasterImageDef object. I don't want to have to look through the whole drawing to find out where the RasterImage is inserted. I can do this with lisp by looking at what the RasterImageDefReactor is associated with, but I can't seem to access the RasterImageDefReactor with .Net.

Any help why, or where to look to get this information would be great, as I've read the Arx help files, and can't seem to find what I'm looking for.

Thanks in advacne.

Tim - Can't really guess about what your code is doing, so if you
can post the relevant part, then maybe we can spot something.

Thanks Tony. Here is the routine I did to find the information I want. I
don't think the formatting will show correctly, so I'll post a file that has
the routine in it.

The problem is this part.

try { DBObject dbo = dboc[0]; }

catch (Autodesk.AutoCAD.Runtime.Exception AcadEr) {
MessageBox.Show(AcadEr.Message); }

catch (System.Exception ex) { MessageBox.Show(ex.Message); }

Hi Tim.

Not long ago on this newsgroup, a bug was discovered
in the indexer for DBObjectCollection.

You can't use it without first doing this:

foreach( DBObject obj in yourDBObjectCollection )
if( obj == null )
throw new InvalidOperationException("null dbobject");

By calling foreach() on the collection it forces the
creation of all DBObject wrappers. If you try to use
the indexer without doing that first, it gets confused
and kaboom.

So, just iterate over the collection using something
like the above first, then you can access the elements
via the indexer.

Hi Tony,

I can't seem to get it to work even with the way you say to go. I get the
same error message after I loop through with the foreach loop. Here is the
code I tried, with all the variations I tired. Am I doing something wrong?
Thanks for your help.

//try {

foreach (DBObject dbo in dboc) {

//try {

if (dbo == null) throw new InvalidOperationException("null DBObject");

//}

//catch {}

}

//}

//catch (Autodesk.AutoCAD.Runtime.Exception AcadEr) {
MessageBox.Show(AcadEr.Message); }

//catch (System.Exception ex) { MessageBox.Show(ex.Message); }

MessageBox.Show("Done with foreach");

for (int j = 0; j < dboc.Count; ++j) {

DBObject dbo = dboc as DBObject;

MessageBox.Show(dbo.GetType().ToString());

}

Hi Tim.

You're describing a problem you're having, but you're
not showing me the code where the problem is.

There's no 'GetReactor' method, so I assumed you meant
the 'GetReactors' method, but the problem there is that
GetReactors() doesn't return a DBObjectCollection.

I can help if you post the relevant code, rather than
little bits and pieces.

Off the top of my head, you should be calling the
GetPersistentReactorIds() method, not GetReactors(),
since the reactors you want are persistent.

I can post the whole code, not a problem, I just didn't know if anyone
wanted to see the whole thing.

I don't see a method for GetPersistentReactorIds(), but in Reflector I do
see the GetReactors() method. It says the GetReactors() method is inherited
from the DBObject class. I just added a line to check to see if the
RasterImageDef has a persistent reactor, and it showed false.

Thanks for your help here Tony, I really appreciate it.

Tony,

In reflector, under RasterImageDef this appears

GetReactors() : DBObjectCollection {
Autodesk.AutoCAD.DatabaseSerices.DBObject }

I thought that meant that a DBObjectCollection was returned. I have
reflector setup to show all methods and properties that can be used with
that class, not just the ones assigned to the class, but the ones inherited
also.

Tim - I didn't notice that GetReactors() has changed
in AutoCAD 2008. In AutoCAD 2007 it does return a
DBObjectCollection, and that's the problem. Not all
reactors are DBObjects, so that code isn't going to
work. In AutoCAD 2008, GetReactors() returns a list
of RXObjects which is what it should do.

Nonetheless, the method you should be calling is not
GetReactors(), you should call GetPersistentReactorIds().

wanted to see the whole thing.

I don't see a method for GetPersistentReactorIds(), but in Reflector I do
see the GetReactors() method. It says the GetReactors() method is inherited
from the DBObject class. I just added a line to check to see if the
RasterImageDef has a persistent reactor, and it showed false.

Hi Tim.

You're describing a problem you're having, but you're
not showing me the code where the problem is.

There's no 'GetReactor' method, so I assumed you meant
the 'GetReactors' method, but the problem there is that
GetReactors() doesn't return a DBObjectCollection.

I can help if you post the relevant code, rather than
little bits and pieces.

Off the t

since the reactors you want are persistent.

Hi Tim.

Not long ago on this newsgroup, a bug was discovered
in the indexer for DBObjectCollection.

You can't use it without first doing this:

foreach( DBObject obj in yourDBObjectCollection )
if( obj
== null )
throw new InvalidOperationException("null dbobject");

By calling foreach() on the collection it forces the
creation of all DBObject wrappers. If you try to use

Hi Tim.  For things like this where you don't have
an

API function in the release you're using, you can
drop

down to the legacy solution (the ObjectARX
equivalent

of the LISP (entget) function).  In the code below,
you

need to change the name of the library (to
acdb16.dll)

in order to use this on AutoCAD 2006.

Call this function on the objectid of the object that has

the reactors on it, and it returns a
resultbuffer that is

the managed equvialent of the association list
that's

returned by the LISP (entget) function. You should
be

able to figure out what to do from there 🙂

[code]

public static class SafeNativeMethods
{
   [DllImport( "acdb17.dll", CallingConvention = CallingConvention.Cdecl,
       EntryPoint = "?acdbGetAdsName@@YA?AW4ErrorStatus@Acad@@AAY01JVAcDbObjectId@@@Z" )]
   extern static public ErrorStatus acdbGetAdsName( out Int64 entres, ObjectId id );

   [DllImport( "acad.exe", CallingConvention = CallingConvention.Cdecl )]
   extern static IntPtr acdbEntGet( out Int64 e );

   public static ResultBuffer EntGet( ObjectId id )
   {
      Int64 e;
      if( acdbGetAdsName( out e, id ) == ErrorStatus.OK )
      {
         IntPtr res = acdbEntGet( out e );
         if( res != IntPtr.Zero )
            return ResultBuffer.Create( res, true );
      }
      return null;
   }

}

Hi
Tim.

Not long ago on this newsgroup, a bug was discovered
in the
indexer for DBObjectCollection.

You can't use it without first doing
this:

  foreach( DBObject obj in yourDBObjectCollection
)
     if( obj
== null
)
         throw new
InvalidOperationException("null dbobject");

By calling foreach() on the
collection it forces the
creation of all DBObject wrappers. If you try to
use
the indexer without doing that first, it gets confused
and
kaboom.

So, just iterate over the collection usin something
like the
above first, then you can access the elements
via the indexer.

Thanks Tony.  Here is the routine I did to find the
information I want.  I
don't think the formatting will show correctly,
so I'll post a file that has
the routine in it.

The problem is this
part.

try { DBObject dbo = dboc[0]; }

catch
(Autodesk.AutoCAD.Runtime.Exception AcadEr)
{
MessageBox.Show(AcadEr.Message); }

catch (System.Exception ex) {
MessageBox.Show(ex.Message); }

Tim - Can't really guess about what your code is
doing, so if you
can post the relevant part, then maybe we can spot
something.

Tony,

  I got it to work the way I wanted it to.  Thanks
again!  I wouldn't have been able to do it without your help.

Hi Tim.  For things like this where you don't have
an

API function in the release you're using, you can
drop

down to the legacy solution (the ObjectARX
equivalent

of the LISP (entget) function).  In the code below,
you

need to change the name of the library (to
acdb16.dll)

in order to use this on AutoCAD 2006.

Call this function on the objectid of the object that has

the reactors on it, and it returns a
resultbuffer that is

the managed equvialent of the association list
that's

returned by the LISP (entget) function. You should
be

able to figure out what to do from there 🙂

[code]

public static class SafeNativeMethods
{
   [DllImport( "acdb17.dll", CallingConvention = CallingConvention.Cdecl,
       EntryPoint = "?acdbGetAdsName@@YA?AW4ErrorStatus@Acad@@AAY01JVAcDbObjectId@@@Z" )]
   extern static public ErrorStatus acdbGetAdsName( out Int64 entres, ObjectId id );

   [DllImport( "acad.exe", CallingConvention = CallingConvention.Cdecl )]
   extern static IntPtr acdbEntGet( out Int64 e );

   public static ResultBuffer EntGet( ObjectId id )
   {
      Int64 e;
      if( acdbGetAdsName( out e, id ) == ErrorStatus.OK )
      {
         IntPtr res = acdbEntGet( out e );
         if( res != IntPtr.Zero )
            return ResultBuffer.Create( res, true );
      }
      return null;
   }

}

[/code]

Tony,

If that is the only way, then
it looks like I can't do what I want in '06
with .Net, as there is no
method GetPersistentReactorIds() method for the
RasterImageDef
class.

Maybe I can figure out another way to do it.

Thanks for
your time and effort, it is appreciated.

- I didn't notice that GetReactors() has changed
in AutoCAD 2008. In
AutoCAD 2007 it does return a
DBObjectCollection, and that's the problem.
Not all
reactors are DBObjects, so that code isn't going to
work. In
AutoCAD 2008, GetReactors() returns a list
of RXObjects which is what it
should do.

Nonetheless, the method you should be calling is
not
GetReactors(), you should call GetPersistentReactorIds().

I
can post the whole code, not a problem, I just didn't know if anyone
wanted
to see the whole thing.

I don't see a method for
GetPersistentReactorIds(), but in Reflector I do
see the GetReactors()
method.  It says the GetReactors() method is inherited
from the
DBObject class.  I just added a line to check to see if
the
RasterImageDef has a persistent reactor, and it showed
false.

Thanks for your help here Tony, I really appreciate
it.

Hi
Tim.

You're describing a problem you're having, but you're
not
showing me the code where the problem is.

There's no 'GetReactor'
method, so I assumed you meant
the 'GetReactors' method, but the problem
there is that
GetReactors() doesn't return a DBObjectCollection.

I
can help if you post the relevant code, rather than
little bits and
pieces.

Off the t
op of my head, you should be calling
the
GetPersistentReactorIds() method, not GetReactors(),
since the
reactors you want are persistent.

Hi
Tony,

  I can't seem to get it to work even with the way you say
to go.  I get the
same error message after I loop through with the
foreach l
oop.  Here is the
code I tried, with all the variations I
tired.  Am I doing something wrong?
Thanks for your help.

//try
{

foreach (DBObject dbo in dboc) {

//try {

if (dbo ==
null) throw new InvalidOperationException("null
DBObject");

//}

//catch {}

}

//}

//catch
(Autodesk.AutoCAD.Runtime.Exception AcadEr)
{
MessageBox.Show(AcadEr.Message); }

//catch (System.Exception ex) {
MessageBox.Show(ex.Message); }

MessageBox.Show("Done with
foreach");

for (int j = 0; j
< dboc.Count; ++j) {

DBObject
dbo = dboc as
DBObject;

MessageBox.Show(dbo.GetType().ToString());

}
