  Hi there,
  I'm creating a tool like Paint Brush, in which a user can make a picture in picture box as well as user can zoom in or zoom out that picture box. I'm able to zoom the picture box with changing its width and height but whenever I used to change picture box's size the image created in it gets lost. how to maintain this stuff.
  Plz help me soon.
  

  
  thanx in advance  
  harry

  without knowing how your cogding tihe image its hard to say, are you zooming one picture, or are you zooming one 'back' pick and renderring the result to another image thus keeping the original in a picturebox? this link may be of some use tho

  Make sure that the picturebox's autoredraw property is set to true, then
  

  
  Try this
  

  
  Dim pic2zoom as stdpicture
  set pic2zoom = picbox.image
  picbox.width = picbox.width * 2
  picbox.height = picbox.height*2
  picbox.paintpicture pic2zoom, 0,0,picbox.scalewidth,picbox.scaleheight
  

  
  As for making it do like microsoft paint, I am unsure.
