Hi, this is maybe a simply-to-answer question:

How to find out whether an image control is empty (= no image shown) or contains an image? Images are coming from the clipboard but could have been emptied by a button with the codeline: MyImage = ""

Hey Guenter

Maybe you got test one of the image properties if there are filled?

Hi Guenter

If I remember correctly, testing image..width will give you zero only if empty.

Hi Fabrice,
my congratulations!! :cheers:

Imho, the ..width property of an image control refers to the control itself, not to its content. MyImageControl..image..width is impossible anyway. I solved the problem by referring to the caption of MyImageControl. I'm starting with MyImageControl..Caption = "" and whenever it is filled from the Clipboard, I set it to "Image" and whenever the image is deleted, ..caption is set back to "". Not a really clean solution but viable.
