My question may be more on style than on correctness of coding.
I have 2 functions in different projects that I'm consolidating into one class.
<br />
CMyClassA<br />
bool GetAbsTime(SYSTEMTIME *startTime, double hourTime, ClockTime *absTime);<br />
...<br />
CMyClassB<br />
bool GetAbsTime(SYSTEMTIME *realWorldTime, double hourTime, ClockTime *absTime);<br />
...<br />
the internals of these functions are different, but they have the same name and the arguments are the same type-wise.
My Question: what would be best way to preserve these function names (as they are now), but have a way of distinguishing each function? 
<br />
CTimeUtilities
<br />
bool GetAbsTime(SYSTEMTIME *startTime, double hourTime, ClockTime *absTime);<br />
bool GetAbsTime(SYSTEMTIME *realWorldTime, double hourTime, ClockTime *absTime);

You can't have both : you need to either change the name of one of the methods or change the type of an argument so that they can be differentiated.
Another option is to combine the two methods into one and pass an additional argument that tells it what code path to execute. The argument can have a default value so that the code that uses that method does not have to be changed if you want.

You could add an extra dummy parameter to one of the functions just like the prefix/postfix ++/-- operators.

thanks _Superman_ and Rick York (and others) for their advice. I may check into your suggestion for sake of learning (dummy parameter like the prefix/postfix operators.)
I believe the work involved to rename would be about the same as additional parameters for each instance in where I make a call to the specific function in question.
Cheers!

for consolidation is best to use an additional parameter, but for clarity is best to introduce different names. The third way: You can do both, via copying the stuff
I personally prefer strongly simplicity and clarity, so I can use also old and long not seen code.
So choose your way...

Erm, I may be a bit thick...
But to read your post:

...
CMyClassB
bool GetAbsTime(SYSTEMTIME *realWorldTime, double hourTime, ClockTime *absTime);
...
You have two classes, and they have method that have the same name. So what? I can do the following if I like:
CCorrect
{
public:
UINT HowCoolIsIain () { return 99; }
};
CWrong {
public:
UINT HowCoolIsIain () { return 1; }
};
main ()
{
CCorrect answer1l;
CWrong answer1l;
cout << answer1.HowCoolIsIain ();
cout << answer2.HowCoolIsIain ();
}
This is not operator overloading. I could have called those two functions Alive and Bob, and it would have generated the same machine code. Done the same thing... It can be handy doing this sort of thing - many of my classes have a GetSize () method for how large they'd be if stored on the hard disk, etc.

to clarify, I want to combine (merge) my two functions into one common class
<br />
CTimeUtilities<br />
bool GetAbsTime(type-A arg1, type-B arg2, type-C arg3);
bool GetAbsTime(type-A myArg1, type-B arg2, type-C arg3);
I don't want to use a new name for either function, but the work seems about the same to change all instances of my function to have a new argument (parameter) as it would to change the name.
alas, i believe I must just bite the bullet and rename
Regards,
John John

Did you read what I said ?
You can add another parameter and it can have a default value which means that you don't have to change any of the code that calls it using the default value. You only have to change the code that would use the non-default parameter. This could cut the amount of work to do considerably.

I have a picture control in a dialog box. I know how to draw by mouse all over the dialog box, but how to limit mouse drawing to some event over specific picture control?
For example: on click on picture control - draw by mouse in this control, on left click - stop drawing.

You must confine the cursor to the rectangle area of the picture control.
In the WM_LBUTTONDOWN message handler, get the rectangle of the picture control using GetClientRect[^] and then call ClipCursor[^] to confine the cursor to the picture control.
In the WM_LBUTTONUP message handler, Call ClipCursor again with a NULL as its parameter.

Thank you for advise. It works, however I have another problem on ClipCursor it clips not to the picture control rectangle, but to the rectangle which has size of the picture control and it begins in the top-left corner of the screen. I guess that i have move this area over my picture control, but how to find coordinates of the top-left corner of the picture control ??

You need to use ScreenToClient[^].

output line 3
output line 4
now i just wish to output the total output lines are 4 ???

Can't you just count them while they are generated ? or maybe there is a counter somewhere that sets the number of lines generated that you could use ?

You could use string::getline[^] in a loop to read the file line by line till the end of the file. In this loop you can have a counter which counts the number of lines in the file.

You should #include Windows.h which will include Winreg.h for you. You may need to link with Advapi32.lib.

If, and that's a big IF, I understand correctly ...
Have a look at the topic of "file association"; google for that and you should be able to
find a lot of information on how to associate a file type/name/extension, in your case a docx file
to a particular application.
The easiest way, non-programatically, is to right-click on the docx file and choose "Open With" and
select the "Choose default program" (that's on vista, I don't have XP) and select your application.

Are you wanting something like UrlEscape() or UrlCanonicalize()?
