I have been trying to pass the object rasterimagedef object with no results. It continues to throw the eNotinDatabase exception. There is another method used as a switch called enablereactors(). Should i refrain from telling the transaction manager to add the newly created rasterimagedef until the new raster image has called the associaterasterdef... or does it not really matter. I can't tell if this is causing the problem. I have tried it both ways and the associaterasterdef() method will not work with the rasterimagedef. Do I have to fully commit() the transaction and start a new transaction before I can attempt to feed it as a database object into the associate method?

You don't pass any reactor id to AssociateRasterDef().
You pass what the name of that method implies (the
RasterImageDef object, which may need to be open
and write-enabled).
That's all there is to it. You don't need to deal with
any reactors.

That is correct. When I code something like:
ri.associaterasterdef(rid);
I get an error in autocad that tells me the entry does not exist in the database.
I am guessing that it is looking for a reactor id that does not exist or that the raster image def is not being handle properly. My question is really where in the code would I put the call to ri.associaterasterdef(rasterimagedef). I found a small tid bit that mentioned setting up a reactionid but nothing on how to handle this. Attached is my version. It is a work in progress. I am posting via OE so I have no idea how this will look.
Thanks, Tony.

Your code isn't calling RasterImage.AssociateImageDef(), which is
what creates the reactor and adds it to the RasterImageDef.

I currently have code working that will grab an image stored on a local drive, create the rasterimagedef dictionary entry, create the raster image object, and display the image in autocad. The program works but there is no reactor link to the image and this is apparent as the xref/image manager shows that the added image entry has no references in the drawing. The drawing does have the image working... but clearly something is not linked correctly. I would normally post my code but I amaffraid it will be a garbled mess like the garbage I have been wading through to find something helpful since the forum update.
My code is very similar in structure to the attached link I found which has the same issue as my code is having. In fact, everything I have found online appears to have this same problem.
http://www.objectarx.net/bbs/viewthread.php?tid=2500 &ex tra=page%3D1
I have been trying to fix this by implimenting the rasterimage.AssociateRasterDef and stuffing the parameter with the new rasterimagedef() entry (both before and after the dictionary entry and transaction) with no luck. The mgd help is very vague on this and mentions that a RasterImageDefReactor must be constructed. I am still learning the C# api and language, with no background in c++ arx. A small example of using the AssociateRasterDef correctly would be very helpful.
Thanks,
Chris Bertschy
Side note: I typically post with OE, but I used the RTF web format for this one. It appears that the only way to get a readable post is to use the web rtf box. Are the users of newsgroup readers being punished??
