Andy,

If you are open to use of a commercial ActiveX component
to replace the VB Picturebox, our MetaDraw 3 will allow you
to very quickly complete your task.

You can try this out quickly,
I've included some sample code below to help you get started,
and you can download the installation kit for evaluation from :
http://www.bennet-tec.com/btproducts/metadraw/installkit/md3_inst.zip
Here's a link to basic info on MetaDraw
http://www.btis.com/btProducts/MetaDraw/MetaDraw.htm

In MetaDraw you can draw shapes either by code
or by allowing the user to draw directly with the mouse
( but still fully under your control. )

For more complex objects made up of multiple shapes,
you can group shapes to form complex elements
or you can simply images you have already drawn with
your standard Pictureboxes as well.

With one line of code you can then allow users to drag the objects
around.
Likewise with one line of code you can allow users to rotate the
shapes.


And of course if you need to Zoom, Scroll, Print, Save and
Reload, . . .
Or even assign hidden data to each shape, . .
It's all in there

This is all very easy -

Here is some sample code

Draw a line by code
MetaDraw.AddObject OT_Line, X1, Y1, X2, Y2
Draw a circle by code ( using coordinates of bounding
rectangle)
MetaDraw.AddObject OT_Ellipse, X1, Y1, X2, Y2
Set the Line Color for just added shape
MetaDraw.LineColor = Some RGB color
Set the Fill Color for just added shape
MetaDraw.FillColor = Some RGB color
Import an image from an existing picturebox
MetaDraw.PictureClip = Picture1.Image
or alternatively
MetaDraw.PictureImage = Picture1.Image
MetaDraw.AddObject OT_Image, X1, Y1, X2, Y2
Allow user to draw a circle with mouse
MetaDraw.EditMode = ED_ELLIPSE
Allow user to draw a line with mouse
MetaDraw.EditMode = ED_LINE
Allow user to drag existing elements
MetaDraw.EditMode = ED_SELECT
Allow user to Rotate existing elements
MetaDraw.EditMode = ED_ROTATE
Get Current Coordinates of Some shape
' can be checked at any time, but may be best in
' Change event when user has just moved the shape
MetaDraw.GetBounds left, top,right, bottom, 0
Get the rotation angle of some shape
' can be checked at any time, but may be best in
' Change event when user has just rotated the shape
Angle = MetaDraw.ObjRotation
Print the Result to user's choice of printer
MetaDraw.ExportDC = -2
Save the current state and then reload to continue editing
MetaDraw.SavePicture "somefile.mdp", Pic_Picture,
Pictype_Internal
MetaDraw.LoadPicture "somefile.mdp", Pic_Picture,
Pictype_Internal
Save the current state in a standard graphic format
MetaDraw.SavePicture "somefile.jpg", Pic_Picture,
Pictype_PNGFile
' other supported standard formats include
' BMP, JPG, PNG, GIF, WMF, EMF

The coordinate system used above is the default
0 - 1000 coordinate space when first creating MetaDraw.
You can also adjust the initial size and coordinate space with
PicWidth, PicHeight, OrigWidth, OrigHeight and ZoomFactor properties.


I hope this is helpful to you.
