Hello,

I have created some c# code that will extract data from CRM into a flat file but I would need this to be based on a plugin in CRM. I followed this tutorial but was a bit lost on how to do this correctly.

For instance, right now my core code the one that goes out to CRM and then pulls the data is called PROGRAM.CS. But in this tutorial, it asks to create a PLUGIN.CS...can someone provide insight on how to accomplish this? For my code to run as a plugin using the code in PROGRAM.CS?

Hi Tekwise,

A plugin does not seem like the best choice to extract data from CRM into a flat file.

You are more likely to write a console app to query CRM and write it to a file

Have a look at the sample code in the SDK under queries

Ok, let's skip that thought for a second.

I would need the plugin to trigger based on the status of an order.

How could I write that piece?

Hi,

you can create two plugins on POST operation: on Create and on Update. in the plugin you need to register a preimages and a post images. You can check if the status in pre is different with post images and if it is different, you can do something...

Thanks everyone - after replaying the plugin execution, it shows that the PreImage and PostImage is NULL. That's why the plugin is failing, what is this Pre/Post Image?

Entity preentity = new Entity("salesorder"); Entity postentity = new Entity("salesorder"); if (context.PostEntityImages.Contains("PostImage") && context.PostEntityImages["PostImage"] is Entity) { postentity = (Entity)context.PostEntityImages["PostImage"]; } if (context.PreEntityImages.Contains("PreImage") && context.PreEntityImages["PreImage"] is Entity) { preentity = (Entity)context.PreEntityImages["PreImage"]; } try { if (null != postentity && postentity.Attributes.Contains("statuscode")) { // do something } catch (Exception e) { tracingService.Trace("Exception: {0}", e.ToString()); throw e; }

Hi,

you can read about crmbook.powerobjects.com/.../plug-in-images-pre-vs-post.

When you register a step in plugin registration tools, you can create a pre or post images also.

Thanks

Hi,

Images are basically snapshot of entity attributes data that you will select while create images, you can have pre and post image, which is basically snapshot of data before operation and after operation. You can't setup pre for create and similarly you can set post for delete. All this you can do while registering plugin.

Thanks
