Q117566

• Microsoft Visual C++, version 1.0

SUMMARY

There are many differences between the source code provided in the Microsoft Press book "Inside Visual C++" by David J. Kruglinski and the source code on the disk that ships with the book. The book contains other errors that are described below.

MORE INFORMATION

Section 4, page 112:

• All references to "CEX06aDialog" should be changed to "CEx06aDialog" to match the existing source code in the files EX06ADLG.H and EX06ADLG.CPP.



• The prototype that the user should to add to EX06ADLG.H should be changed from

  
           void CEx06aDialog::OnOK(); 

  to

  
           virtual void OnOK(); 




• Section 4, page 114:
  
  

  In the CEx06aDialog::OnHScroll function in the book, the three occurrences of the line "pScrollBar->GetScrollRange(&nMin, &nMax)" in the switch statement are not in the source code found on the sample disk. The line "pScrollBar->GetScrollRange(&nMin,&nMax)" is needed at the beginning of each one of the case statements to set the minimum and maximum values of the scroll bar before the thumbpad position can be changed.




• Section 11, page 122:
  
  The line, "pDC->TextOut(0,0,'Press the left mouse button here.');" should be highlighted.



• Section 10, page 130:
  
  The phrase in the second include statement, "ex07bdlg.h", should be replaced with "ex07bvw.h".



• Section 10, page 131, paragraph 1:
  
  The fourth line should have the acronym "DLL" rather than "DDL".



• Section 8, page 205:
  
  In the file EX12BVW.CPP, the source code in the book for function "OnCreate" is different than the source code provided on the sample disk. In this instance, the source code in the book is the better version to use. The following code is an example of CEx12bView::OnCreate as shown in the book:

  
           int CEx12bView::OnCreate(LPCREATESTRUCT lpCreateStruct)
           {
              if(CEditView::OnCreate(lpCreateStruct) != 0)
              {
                 return -1;
              }
  
              VERIFY(m_pFont->CreateFont(12,0,0,0,400,FALSE,FALSE,0,
                                         ANSI_CHARSET,OUT_DEFAULT_PRECIS,
                                         CLIP_DEFAULT_PRECIS,DEFAULT_QUALITY,
                                         DEFAULT_PITCH | FF_SWISS,"Arial"));
              SetFont(m_pFont);
              return 0;
           } 

  The same function on the sample disk has three major differences:
  
  
  1. An unreferenced variable, "CFont font", is included at the beginning of the function.
  
  
  
  2. The if statement in the function checks to see whether CEditView:: OnCreate equals -1 instead of another non-zero value.
  
  
  
  3. The function uses the ASSERT macro instead of the VERIFY macro. ASSERT evaluates and checks its argument only in DEBUG mode while VERIFY passes its argument to ASSERT in DEBUG mode and evaluates the argument itself in RELEASE mode without checking the result.
  
  
  



• Section 9, page 252:
  
  The first highlighted line in the function "OnClickedEnter" is missing a semicolon at the end.
