How to get a hDC from a PureBasic image?

Given a PureBasic image created by CreateImage(), how can I get a hDC (device context handle) for drawing with Win32 functions?
I used to be able to do this in older versions of PureBasic:
Code: Select all
hDC=StartDrawing(ImageOutput(Image))
Unsurprisingly, this undocumented feature no longer works.

Still working with PB 5.71 LTS
Code: Select all
CreateImage(0, 320, 200, 24, #Blue)
SetRect_(fill.RECT, 25, 50, 100, 150)
hdc = StartDrawing(ImageOutput(0))
FillRect_(hdc, fill, GetStockObject_(#GRAY_BRUSH))
StopDrawing()
ShowLibraryViewer("Image", 0)

Sure it does. Post a little snippet showing the failure, please.

I should have included some sample code. I don't know in what instance this was failing.
This is my mistake.
