Errata: Second Printing
The following is a listing of various errors found in the text for the second printing. Errors in previous printings are found in a list following this one. Errors in older lists may have been corrected in newer printings. If you have found an error in your copy that you do not find in this list, please notify the author through the feedback page.
Chapter 3: All VB Code boxes and references to VB Code Boxes are incorrect. All VB Code Boxes are numbered as 7- and referred to in the same way. All references match, but the they should be numbered as VB Code Box 3- instead of VB Code Box 7-.
Page 154: In the next to last line of Exercise 6, “text” should be “test”.
Page 232: In VB Code Box 6-7. The statement immediately before the End Sub statement is now:
FileClose()
It should be
srdReadFile.Close()
Page 232:
·  · In VB Code Box 6-7, the statement:
Dim intNumPrices As Integer = 0
should be
intNumPrices = 0
Otherwise, it declares intNumPrices as a local variable. Note the complete program shown in VB Code box 6-12 is correct.
·  · In VB Code Box 6-7, two lines of code are missing in the form_load procedure. These lines of code are:
strPartID(intNumPrices) = strFields(0)
decPrices(intNumPrices) = CDec(strFields(1))
These additional lines of code come immediately prior to the statement that increments intNumPrices, that is, intNumPrices = intNumPrices + 1
Note the complete program shown in VB Code box 6-12 is correct since it includes these code statements.
Page 237: In VB Code Box 6-11 The statement immediately before the End Sub statement is now:
FileClose()
It should be
srdReadFile.Close()
Page 245: In VB Code Box 6-14. The statement immediately before the End Sub statement is now:
FileClose()
It should be
srdReadFile.Close()
Page 250: In VB Code Box 6-18. The statement immediately before the End Sub statement is now:
FileClose()
It should be
srdReadFile.Close()
Page 266: In Exercise 6-7. The next to the last line should refer to “customers” rather than “salespeople.”
Page 278:
·  · Midway down the page, the Function definition statement should be:
Function decSum(ByVal decValues() as Decimal) As Decimal
There should be no reference to the intNumValues parameter in the function declaration statement.
·  · At the bottom of the page, the function reference statement should be:
txtSum.text = decSum(decPrices)
There should be no reference to the intNumValues parameter in the function reference statement.
Page 279: The fourth line of VB Code Box 7-2
It should be
decAverage = decSum(decValues) / intNumvalues
There should be no reference to the intNumValues parameter in the decSum function and the divisor should be “intNumValues” instead of “intNumPrices”
Pages 325-326: To save the data to that is added on the third form for Projects 6, 7, and 8 to the text file, it is best to use
Printline(n, variable1 & chr(9) & variable2)
instead of Writeline
Page 342: In VB Code Box 8-8
·  · Both references to “udtEmployees(intCounter)” in lines 10 and 13 should be to “udtEmployees(intEmpCntr)”, that is, line 10 should be
ReDim Preserve udtEmployees(intEmpCntr)
·  · Line 13 should be
With udtEmployees(intEmpCntr)
There should also be a statement to close the StringReader operation at the end of the procedure, that is, add the following statement immediately before the end of the procedure:
srdEmployee.Close
·  · The indices in Lines 16 and 17 should be changed as follows:
.strSSNum = strFields(3)
.strPhone = strFields(2)
This last error causes the bottom portion of Figure 8-7 to be incorrect in that it shows one telephone number and two SS numbers under the heading “Telephone #”
Page 370: For the discussion in this section, the txtHrsWrked text box on the frmShowEmp form must be renamed as txtHrsWorked
Page 399, Exercise 6:
·  · In addition to renaming the Vintage7 application, you should remove the lstTypes list box and the associated label so your Vintage main form appears as shown in Figure 9-4 at the top.
·  · In addition, the vintage.mdb data base should be downloaded to the c:\vbdb folder instead of to the bin folder of the new Vintage9 folder.

Change “cdec” to “CDec” .

“Sub LoadFile” should be “Sub FileLoad”
Page 364, VB Code Box 8-19:
