Picture Box Question

I was looking at the following

http://www.vbworld.com/graphics/tip49.html

and its exactly what i need execpt i want it to scroll a image from the left and then stop when it reachs the end of th image.
If anyone knows please let me know

Thanks
:D

The easiest way to do it is to have two picture boxes.

picContainer
picImage

add a scroll bar inside picContainer
paste picImage inside picContainer and then measure the difference between the size of the two boxes.

This is air code, so it may not be exactly right, but it should get you close

Sub SetupPictureBoxes
dim iPicWidth as integer
dim iContainerWidth as integer
dim iDifference as integer

iPicWidth=picImage.Width
iContainerWidth=picContainer.Width

idifference=iContainerWidth-iPicWidth

if iDifference>0 then
hscroll1.Max=iDifference
hscroll1.enabled=true
else
hscroll1.max=0
hscroll1.enabled=false
end if

end sub

Sub hscroll1_scroll
' subtract the value of hscroll to move the picture box
picImage.left= - hscroll1.value
end sub

Thanks for that!

But.... ( theres always a but ;) )

Iam trying to make it so there is no scroll bars that the image inside the picture box starts scrolling to the left when the page loads. Is there a better way to do this then using picture boxes ?

Take a look at this post. The code I posted here is for scrolling text in a picture box, but you should be able to modify it to scroll an Image instead.

If not, let me know and I'll play around with it.

If you just want it to scroll across the form, you can use one picture box and a timer control. If you don't want to use a picturebox at all, you'll have to use API blitting functions. There is a lot of info on the net about blitting with VB. I don't know much about it. I just copy code when I need it.

' Set the timer interval to whatever makes the picture move at the desired rate

More air code

Sub Timer1_Timer
' This will make the picture move back and forth
Static fMoveRight as boolean

with picture1
if fMoveRight then
if (.Left + .Width) < Form1.Scalewidth then
.Left=.Left + 1 ' change the movement amount if needed
else
fmoveright=false ' change direction
end if
else
if .left>0 then
.left=.left -1
else
fmoveright=true
end if
end with

end sub

Thanks hack for that

Cafeenman, that code was good and worked well but it moved the picture box not the image inside the box. Is there any way you could change this to make it move the image. I would be greatful. :)

Sub Timer1_Timer()
Static fMoveLeft As Boolean

With Picture1
If fMoveLeft Then
If (.Left + .Width) < Form1.ScaleWidth Then
.Left = .Left - 1
Else
fMoveLeft = False
End If
Else
fMoveLeft = True
End If
End With
End Sub

You have to use API's if you want to manipulate a picture without the picture box. You can find that info by looking for bitblt and visual basic on the web. I don't know how to do it.

If it's just the border of the picture box you find objectionable, you can turn it off so it just looks like a picture. It does use more resources, however.

I don't do much work with bitmap manipulation, so I can't really help you more than that. Sorry.
