This moves method comments from the .cpp file to the .h file, where users of the methods can find them. This also makes it possible for the IDE to show the comments when you mouse-hover over the method name, though Visual Studio is a bit weak in this regard. Also, added "override" keywords on overridden methods. Reasonably current versions of popular compilers seem to support this. Also, don't have the return type on a separate line in the .cpp file. The motivation for the practice -- quickly finding a method definition with "^name" -- is less useful in C++ than C, and modern IDEs provide more convenient ways to do the same thing. Also, do some more conversion from unsigned types to uintXX_t. This commit is primarily for the "app" directory.

* Here's the really strange part of the affair. The GetTextLength call
|
|
* shown in the MSFT KB article doesn't return the correct number of
|
|
* characters. The CRichEditView code in MFC uses a GetTextLengthEx
|
|
* call, which is documented as being part of the CRichEditCtrl but
|
|
* doesn't appear in the header files. Call it the hard way.
|
|
*
|
|
* If you print a "raw" file with carriage returns, and you use version
|
|
* 5.30.23.1200 of "riched20.dll", you get "9609" from GetTextLength and
|
|
* "9528" from GetTextLengthEx when the document's length is 9528 and
|
|
* there are 81 carriage returns. The value you want to use is 9528,
|
|
* because the print code doesn't double-up the count on CRs.
|
|
*
|
|
* If instead you use version 5.30.23.1215, you get the same answer
|
|
* from both calls, and printing works fine.
|
|
*
|
|
* GetTextLengthEx is part of "riched20.dll". Win9x uses "riched32.dll",
|
|
* which doesn't support the call.
