Invalid Picture in Image Control?
Versions des environnements
Network:
Windows 2003 Server
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.
I'm working in VFP 8 but could switch to 9 if there were a way to do this in 9.
Thanks for any help you can provide.
