GUICtrlCreateGraphic - working on last GUI created

[enaiman]

Hi,

I'm not sure if this is an intended behaviour or a bug.
GUICtrlCreateGraphic since it doesn't use a window handle it creates the grapthic on the last GUI created; if that GUI was deleted GUICtrlCreateGraphic will fail.

Here is a sample script; it might not be the best example but it shows the above behaviour. Once the last GUI was deleted GUICtrlCreateGraphic will always return 0.

Maybe a future release might consider using a window handle in GUICtrlCreateGraphic call?

Thank you

This is not a bug. ANY control you try to create will fail. Controls are created on the GUI that is set internally as the "current" GUI. Since you deleted the current GUI, creation fails. To control what GUI controls are created on, use GUISwitch().
