Chaps,

VB4 does not have a MOUSEOVER event, at least as far as I can tell it
doesnt. What I want is to change the picture in an image control when the
mouse moves over it, then back to its original picture when the mouse
leaves. I know I can do this if a mouse button is pressed, however thats NOT
what I am after - just a mouse, wandering around the screen with no buttons
down, with images changing as the mouse moves over the image controls - any
thoughts ?

Use the mousemove event.

If the control you want to capture the events with does not have a mousemove
event, subclass the control and capture mousemove events with the API

One way to do it (and I've posted this in several ways before) is to use
the MouseOver event of a control to change the image to the MouseOver image
and to start a timer going (every 1/4 or 1/2 second is usually fine).  In
your case, since you're using multiple controls (aka a Control Array), you
might want to set a variable equal to the Index of the control that fired
the MouseOver event.  In the Timer event of the timer, you get the mouse
position (GetCursorPos in conjunction with ScreenToClient works fine).
Compare the mouse position with the Left, Top, Width and Height of your
control.  If the mouse is inside the control, then do nothing.  If its
outside, then restore the image and reset the timer to being off.

This technique is relatively fast and easy to implement and avoids those
"jerk the mouse off the control" errors that some other techniques (like
SetCapture) will engender.

It often shows an excellent command
of language to say nothing.

I do that a lot in multimedia programs. What I do is to place a code in
MouseMove event of the control with a flag that loads the picture in the
image control when the mouse is in it. It looks like this:

  Form MouseMove
        if bLoad = False
          Picture.picture = LoadPicture(<name of BMP when NOT passing
over>)
          bLoad = TRUE
       endif
  end

 Picture  MouseMouse
    if bLoad = TRUE then
      Picture.picture = LoadPicture(<name of BMP when passing over>)
      bLoad = FALSE
    endif
  end

You can, as Jim said, use the index propertie to control an array of
pictures. The most important is to use any flag that controls the right
loading of images in the picture, and to create a way to assure the
Form.MouseMove event, as sometimes, when moving the mouse very fast, it
doesn't happen and the picture control will remain with the image of the
mouse move event.

Yours,
