Hello I'm using 5.2 of imageen. I have added a imagenmview and a imagenview on a form. I'm using the mview to load images from a sql blob field and have associated nvew to show the images when click on in mview.All this works find except when I click on the form and there is no image loaded from the blobfield.When I click to exit the form I get a Access Violation on Read address 00000000. I use the simple form.close when leaving the form. I do not get this error when the mview has images from the tblobfield. Anyone else have this issue?
I do not work with blob fields much, but having said that, I highly doubt the problem is caused by ImageEn library code. I suspect your own code, probably located in an event is causing the problem. Are you clicking on the form itself or on TImageEnView? Try putting breakpoints in all TImageEnView events and compile in debug mode. EurekaLog or others could also be used to determine where the exception takes place.
I ran with eureka log and it is complaining on the assign TIOParams in the imageenio. So you maybe right. I will look into the assign section and see why it is failing. I wonder though why the assign would be a issue on a blank image.
