If I use an image n.png in my program and run it from the IDE the image becomes locked until the IDE is restarted. For example, if I have the image loaded in Photoshop I can't edit and resave the image until I started the IDE.
Filippo is actually experiencing it with his fgAktien program in the German forum.
I compiled Filippos program on the desktop and the same problem remains.
Once the image file has been accessed it is blocked.
I encounter regulary the same kind of problems when trying to update image files for buttons. I always need to close the IDE, update the files and run the IDE again.
I remembered having seen once a thread, and found this one.
Just found a temporary fix yesterday...
1 - load the picture file in your favourite editor
2 - remove the picture in the Designer (you have to clear the "Image" field of your Image control, or delete the picture's name from an ImageList)
3 - run your app in B4ppc
4 - exit your app
You can now save the picture file without having to re-run B4ppc
Note that steps 1 and 2 can be swapped.
Too much work when we can just exit b4ppc, do the work in our image, and then re-load our app in b4ppc...
Your aproach may cause some delays as one tends to froget that the image reference is missing...
