Image Refresh

[RichardH]

When I include an image on a form and assign the picture property as “mypicture.jpg” the image displays, then I copy a different image into the same file name “mypicture.jpg”. The new image will not display until I exit and restart VFP6. Is there any way I can display the new image without having to restart.

You cannot refresh an Image control, but if you restate the picture property after you have copied a new image to "mypicture.jpg", that will effectively refresh the control.

VFP will sometimes have the image in memory and when the name is the same, it will not show the newer image.

The trick is just to blank your image control and assign it again to the image control (which could be done in the Refresh() method).

I can't agree with you on this.

(which could be done in the Refresh() method).

I assume you mean THISFORM.refresh()?

If so, that could mean a lot of unnecessary processor activity, nor is there any need to 'blank' the picture property.

THISFORM.Image1.Picture = [mypicture.jpg]

after copying the new image, is sufficient in its own right.

Chris, you are right.

I made a control like that myself, but I forgot that I put it in a container, which does have a refresh method.

But, we have had some trouble with image refreshing in the past, and Fox did keep it in memory, this was very strange behaviour.
