Panel with picturebox scrollbar

[Thiru .Net]

hi wagner,
i have a doubt in panel control in windows application.

i have a panel control wherein i have put a picturebox control.
i show picture into picturbox control.

now i need to zoom in and zoom out the picture in the picturebox
control.
the picturebox control is within panel(autoscroll is enabled true)
scroll bars are enabled.

PictureBox1.Width = PictureBox1.Width + 25
PictureBox1.Height = PictureBox1.Height + 25

the problem is the picture goes only to right side when it gets its size
enlarged.

then i used left and top properties

PictureBox1.Width = PictureBox1.Width + 25
PictureBox1.Height = PictureBox1.Height + 25
PictureBox1.Left = PictureBox1.Left - 20
PictureBox1.Top = PictureBox1.Top - 5

the above code streched the picture both left and right side...but the
problem is i can scroll right side and see the picture but i could not
scroll left side to see picture streched on the left side.

i need to strech and zoom in and out both sides and should be viewed
thru scrollbars both sides using panel.

thanks in advance,

regards,
Thiru.

Hi,

Will you be so kind not to address messages to certain people active in this
newsgroup, especially not in this impolite way.

If you want to refer to another message, than connect it as a reply to the
message from the one who has answered you.

What your ask is AFAIK not not standard, however I *thought* that there is
in the 101 samples (advanced GDI) one that shows what you want to do.

I hope this helps,
