Re: [Gambas-user] Picture Viewer Project

[Michael S. <mi...@es...>]

I've gotten past the Null Object error.  Here is my code:

PUBLIC SUB fileList_Select()
  DIM hPic AS Picture=20
  DIM tempPic AS String=20
=20
  tempPic =3D myDir & "/" & Str(fileList.Current)    =20
  hPic =3D NEW Picture
  hPic.Load(tempPic)
 =20
  MyPicture.Picture =3D hPic =20

END

But whenever I pick any picture filename I get the error "Unable to load
picture".  The documentation says that the PictureBox control can load
jpegs.  The picture I tried it on was a jpg.  Does that make a
difference?  What am I doing wrong?
