Does CopyIcon need to Destroy the Handle

[RMS001]

Hi - It's been a while since I visited. The best VB6 help was always here.

Is there a reference created, or simply a long variable assigned a value, when using CopyIcon?

Private Sub Form_Load()
hIcon = CopyIcon(Image1.Picture.Handle)
End Sub

Private Sub Form_Paint()
DrawIconEx Picture1.hdc, 10, 10, hIcon, 12, 12, 0&, 0&, DI_NORMAL
End Sub

'is this neccessary
Private Sub Form_Unload(Cancel As Integer)
DestroyIcon hIcon
End Sub

DestroyIcon not only destroys the icon it also frees any memory associated with the copied icon, so yes, it's best to use it once you're finished.

Hope this helps

I'd use DestroyIcon, since there may be some system resources allocated by the CopyIcon call that are only freed on DestroyIcon
