Hi 030 students,

    Here is a problem that I just duplicated, and its solution.
The Horizontal Scroll Bar is named hsbWidth in my program.
                                   --------

>I was just working on my project and everything works until I get to the

>lblCurrentWidth. However, when I try to scroll the whole form goes black
>and it gives me a Run-time error '380': Invalid property Value. When I

    I duplicated this error by changing my hsbWidth.Max to 1000 or 2000
which is a very, ridiculously large number.  When I do the hsbWidth_Scroll
event, by dragging the thumb of the scroll bar, it makes the whole
frmWidth quickly BLACK, because the Line1 object has become SOOOOOO WIDE,
SOOOOOOOOOOOOOOO fast.

    If I set hsbWidth.Min to 0, which is ILLEGAL, then when I scroll the
other direction, I eventually get the Run-Time error 380, since a line
cannot have a width of 0, or rather Line1.BorderWidth = 0 is ILLEGAL.

    So set your hsbWidth.Min to 1 and your hsbWidth.Max to 20 or 30 or so.
Set the hsbWidth.SmallChange to 1 or 2 and the hsbWidth.LargeChange 
to 4 or 5 too.  The default MAX property for a scroll bar is 32,767 and
the default MIN value is 0.  The default SmallChange is 1 and the default
LargeChange is 1, so it is usually the Scroll event that gets you in 
trouble more quickly!                  ------

    Setting the proper property values at Design time is a big part of 
Visual Basic programming.
