picturebox scroll bars ;)

well i added an image to my dialog (inside a picturebox)
and added scroll bars (H and V)
and when i have a picture and scroll the bar
it doest scroll through the whole picture.

code:

Private Sub Command12_Click()

   CommonDialog1.DialogTitle = "Load Picture"

   CommonDialog1.InitDir = App.Path & "\Images"

   CommonDialog1.Filter = "Bitmaps (*.bmp)|*.bmp|Jpegs (*.jpg)|*.jpg|Gifs (*.gif)|*.gif"

   CommonDialog1.ShowOpen

   Image1.Picture = LoadPicture(CommonDialog1.FileName)

   HScroll1.Max = Picture7.ScaleWidth

   VScroll1.Max = Picture7.ScaleHeight

End Sub



Private Sub VScroll1_Change()

   Call Image1.Move(Image1.Left, -(VScroll1.Value))

End Sub



Private Sub HScroll1_Change()

 Call Image1.Move(Image1.Top, -HScroll1.Value)

End Sub

also if the image is smaller than the picture box id like
it to be centered in the picture box
and the scroll bars to be disabled

please help me out here

thanks alot :)

hello,

i'm ressurrecting this topic because i am trying to do the same thing. i've got an image that displays in a picturebox according to whatever the user selects in a dirlistbox, but most of the images that get selected and displayed are 3-4x as large as the picturebox. based on my research, microsoft hasn't implemented any useful image controls in even the newest versions of VB. i'm using VB6 by the way.

is there any way to allow the user to "grab" and pan the image within the box like you can "grab" and pan a .pdf document? or at least is there some relatively easy way of installing scrollbars to do the same? i tried modifying this guy's (broken?) code but couldn't get it to work.

thanks

hey ^^
heres a link to the ocx

im not sure about the image grabbing but the scroll bars work really well
maybe you can use the mouse move event and check if the mouse button is
pressed down. then use the windows properties to move it.

good luck :)
