    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

    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.
