UNCONFIRMED  errors and comments from readers: 


{22}  Hooking Up The Second Form To The First;
In the Event Handler, enter this one line of code: frmCustomerDetails.Show()

Where do you add this? When I added it to the button click - which as has been coded
to this point displays a Message Box for all four buttons - the Customer Details form
now shows for each and every button click. Illustrations would be nice right about
here.


(36)  2nd to last line of Example 2-2;
2nd to last line of Example 2-2 should read

"frmCustomerDetails.CompanyNameParameter = companyName"

(as already correctly shown in Examples 2-1 and 2-3)
I suspect that each of these code examples is intended to have different 
highlighting applied, to highlight the relevant sections being discussed.


[39]  Chapter "Adding New Tables"; 2nd paragraph;
Add -> DataTable 
should be:
Add -> TableAdapter


[48]  Example 2-6 continued, top of page;
In the final case statement of the entire example, you've copied code from the
previous case statement.  In my opinion, easily missed in testing if the student is
editing the code.  Here is what you have:

Select Case btnName
  Case "btnSupplierFind"
    frmSupplier.CompanyNameParameter = _
         filteredView.Item(0)"CompanyName")
    frmSupplier.Show()
  Case "btnCustomerFind"
    frmCustomerDetail.CompanyNameParameter = _
         filteredView.Item(0)("CompanyName")
    frmCustomerDetail.Show()
EndCase

And it should be:

Select Case btnName
  Case "btnSupplierFind"
    frmSupplier.CompanyNameParameter = companyName
    frmSupplier.Show()
  Case "btnCustomerFind"
    frmCustomerDetail.CompanyNameParameter = companyName    frmCustomerDetail.Show()
EndCase

Because you've just set companyName to the value you want from the dialog box.


(68)  Example 3-7;
In the code, you've named the button btnPrev whereas in the rest of the preceding
examples it's been called btnPrevious.  A minor oversight.


{485}  2nd Paragraph;
The book says:
"Output:
0 5 10 15 20"

But the actual output from running the program is:
"Output:
5 6 7 8 9"


[520] Figure 18-6;
Figure 18-6 "Unboxing" - The figure looks as if it was originally created for C#. "int" is not a valid type in VB, VB doesn't use line terminators (;), and the typecast specified is incorrect (should use DirectCast or CType instead of "(int)".
