Canvas does not allow drawing HJÆLP!

Det er nok en følgefejl af noget andet
på http://www.delphifaq.com/fq/q4053.shtml:

Msg 'Canvas does not allow drawing'
Q:
What does the error message 'Canvas does not allow drawing' mean?

A:


you may have run out of resources, which means a new DC cannot be
allocated. Usually this is a result of not freeing unused DCs or other
objects

you are attempting to draw to an device context that is not yet valid.
Such as in the create constructor of a component.

you are trying to draw on a canvas while your last draw-operation has
not finished yet. In this case you can use Canvas.Lock or Canvas.TryLock to fix it.

Ligger din kode i en create constructor (punkt 2)?

Hmm det virker underligt.
Det er nok mest den første kategori den passer i.

Vilken type er SettingLbl?? En TListBox??

Nej en label
