It's a performance issue. This is processing I'd have to do if I wanted to load an image, but I don't want to load it just to find out it isn't georeferenced and therefore don't need it anyway. In this application there could be a lot of non-georeferenced images. The solution I have right now is to scan the image for an indicator string. Working so far but it's bound to fail sometime. After that I may try using the GDAL libraries. Thanks, Rick

The following is the generated MainWindow.xaml for an WCF runtime aplication that simply shows a red dot on a blank map control. Works just fine. Why, when I set UseAcceleratedDisplay="True", do I see nothing on the map control?

I have a task to scan a folder for georeferenced images. There might be a lot of images, some quite large, and some not georeferenced. The spatial information can also be either embedded or in a world file. Is there anything available in the runtime that can tell me if "C:\someFolder\file.x" is georeferenced. Thanks, Rick Cote Thalse Systems

I've also tried: "PARENT_ID = '{9dba6278-347d-4148-9e38-f4681fc88c29}' I'm using the ArcEngine v. 9.3.1, and the data source is a file geodatabase. Thanks, Rick

I'm sure that there's a simple answer to this but I'm missing it. I want to query a feature class that has a column named PARENT_ID. The type is GUID. My where clause is: PARENT_ID = '6c1d6f56-b4d9-43ba-ac0a-038699229b6b' I have records with this guid, but the featureClass.Search isn't returning features. Is there some trick to querying for a guid? Thanks, Rick
