AutoSize Issues

[Joe Cool]

I am trying to display several images on a standard Windows Form. Each
image is displayed in a PictureBox control that is 180,130 in size. I
get the Primary Screen size to determine how many images will on one
line of images. I have a form boolean variable that I set to true in
the ClientSizedChan ged event handler. In the loop where I am
displaying the images, I check this boolean, and if true, I set the Y
coordinate loop counter to the actual Y location of the last image
placed.

This seems to work OK for the first line of images drawn after the
first client size changed event, but it goes haywirea after that,
drawing each image at some random location on a line, with several
lines since the last image drawn.

It seems unpredictable on just how the client size is adjusted on an
autoscroll generated event.

Any help would be appreciated.

The client size shouldn't be changing if all you're doing is scrolling.
As for the rest of your post, I admit it's not really all that clear to me
what you've implemented, or that your approach is actually appropriate for
the goal. However, assuming that what you're trying to do is fill a form
with PictureBox instances, you may want to look at the FlowLayoutPanel
control. You can add arbitrarily many child controls to it, and it will
automatically handle laying them out to fit as necessary.

Joe,

Have a look at the Anchor and Dock properties.

Trying to do it by hand will fail almost forever.
That was going when all screens had a standard rectangle.
