Win32 API Programming with Visual Basic
by Steven Roman


Following are the changes made in the 1/00 reprint.


Here's a key to the markup:

        [page-number]: serious technical mistake
        {page-number}: minor technical mistake
        <page-number>: important language/formatting problem
        (page-number): language change or minor formatting problem
        ?page-number?: reader question or request for clarification


{15} In the fourth paragraph the second sentence used to read:

	and other files."


(18) The first line after the section heading "The Basics" used to

paragraph now reads:

        "We should also note that the FindWindow function allows

	that contains the value 0)."

        "The functions are defined as follows:"


(136) In the first paragraph in the section "A Complete Example," the
following sentence has been added to the end of the para:

        "The GetException function below just returns the symbolic
	constant from Table 8.1 when given the constant's value."


(163) The heading used to read:

        "Getting a process handle..."

<179> The first paragraph has been replaced by:

        "Note that, by comparing the memory maps for a process under
	Windows NT and Windows 95/98, it is possible to see that Windows
	95/98 puts the Win32 (and other) system DLLs in a different
	location than Windows NT. For example, under Windows NT,
	KERNEL32.DLL is just under the 2GB mark, which is in the area
	of memory reserved for applications. However, under Windows
	95/98, this DLL is at the 3GB mark, in the area of memory 
	reserved for the operating system."


(179) The last sentence on the page has been deleted.


(180) The first sentence has been replaced with:

        "The first method is the simplest, but works only if the
	application has a uniquely identifiable top level window
	caption that does not change."

	giUsageCount."


<202> In the first paragraph in section entitled "Mutexes", the words
"signaled" and "nonsignalled" were reversed. The paragraph now read:

        "A mutex is a kernel object that can be used to synchronize
	threads running is different processes. A mutex may or may not
	be owned by some thread. If a mutex is owned by a thread, then
	the mutex is nonsignaled. If the mutex is not owned by any
	thread, the mutex is signaled. In other words, for a mutex,
	owned is equivalent to nonsignaled."


(242) In Figure 14-1, at the top of the figure under "PE Signature"
the two "Ohs" in the boxes are now zeros.


(263) The first line used to:
