You can probably do that in PictureVal.Assign method (or how do you assign your picture)? Give this property an assign method and test with LoadPicture.

>>>I'm trying to determine if the image that I assign to the Picture value of an image control is actually being displayed. In other words, if the user selects a corrupt image file to be displayed on the form in my image control, it won't be displayed. I want to be able to trap that and provide some feedback to the user so they don't think the form isn't working.

>>>Is there a way to trap this?
>>>
>>>As far as I can tell, the image control provides no feedback regarding invalid files ... it just doesn't display the picture. I'm already checking the extension and looking at the first 4 characters of the file to try to determine if they've selected a true image file. But none of this protects against corrupted image files.

If it's not broken, fix it until it is.
