But in this case doc is also a child class no?

Yes, sort of. Since the Document class is primarily there to hold your data, it doesn't have its own window (that is what the View is for). For messages/events purposes, it is considered a child of the frame class, though (and in that respect, it is on the same level as the View class(es)).

I just debugged with sample application. Answer seems like this.
As per the CFramWnd’s implementation, it first routes the message to current view. The handler defined in the view class will invoke. If no handler inside the view class, CView class will pass the document class attached.

Yeah, debugging is good. Keep ahead!

Hi All,
I have a VC++ application its a bit big application having more than 10 ATL
components. The application is client/server architecture with
multi-threading. The server does the data trasnfer from one database to
another using ODBC/OLEDB.
If at all I want to change the technology from VC++, is it advisable to
migrate it to .NET? Can any one comment on the migration plan from vc++ to
.NET?

hi everybody,
i have an issue regarding running dos comds from vc ++ program . If we want to run user interactive command from the vc++ how can we do it.
to amplify the issue , there is a command which says gcc -v, now the output of this command is a one time single line output, which requires no user input. Now i am able to run such one line commands through vc++ GUI, however, I am having problem in running commands which require user input, say if there is a command which says gpg --gen-key , now this command when run in command prompt prompts user for various inputs like choose encryption algo, give user name , email id, etc..... .Now How can a GUI be build to run such commands which only get completed after taking various inputs from user ...If you feel i need to study more kindly show me the path to study something in the right direction...the field and subject is so vast otherwise..
can any one please guide me if there is another approach or a better way to do .......in vc++ using MFC .
thanks to all who took pain to read the query atleast....

Are you wanting to pass data to your console application from your GUI application? If so, see here and here.

Hi,
If I can declare a function as
void Show(int i = 1729,double d);
But I can't call this function by passing only 2nd argument then what is the use of that function? OR How to use this function (to pass only 2nd argument)?
ex.
void Show(int i, double d = 3.14);
void Show(int i = 1729,double d);
void Show(int i, double d)
{
printf("\n\t %d %0.2lf",i,d);
}
main()
{
Show(); // Output 1729 3.14
Show(12); // Output 12 3.14
Show(45,5.6); // Output 45 5.60
Show(23.9); // Output 23 3.14 ....... But can I get output as 1729 23.9 ?
}
Thanks & Best Regards,
Aniket Salunkhe

default arguments only starts at the end of the parameters list...

Only the last arguments in the arguments list can assume a default value.
"void Show(int i = 1729,double d);" is not correct
If you need to pass int or double you can use polymorphism ...
void Show( int i= 1729 );
void Show( double d=3.14);
void Show(int i, double d);

This is function overloading ... not polymorphism.

also called "function polymorphism"

Polymorphism is generally used with reference to classes or objects, and it deals with method OVERRIDING, not overloading.

Arguments with default values must come at the end of the argument list. C++ does not provide a syntax for specifying missing arguments.
Another thing you might be seeing, since you are using numeric arguments, is that the compiler will automatically convert numeric constants to the correct type.
The best way to do this would be:
void Show(double d,int i = 1729)
{
printf("\n\t%d %lf",i,d);
}
main()
{
Show();
Show(12);
Show(5.6,45);
Show(23.9);
}

You cannot pass just the second parameter. If you change the declaration so that the default parameters are the last arguments to your function, you can pass the first arguments and skip the default ones (if desired), but you cannot do it the way you are trying to.
Also, you cannot create the same function with the same arguments and different default parameters.
Aniket Salunkhe wrote: void Show(int i, double d = 3.14);
void Show(int i = 1729,double d);
void Show(int i, double d)
Declaring all 3 of those will give you a compiler error.
void Show(double d, int i = 1729);
Show(3.14);
Show(3.14, 2000);

Neither C nor C++ support "named parameters." See here for more.

I've a weird problem making me crazy !!!
I've to read a sequence of dates from a text file and convert these dates into time_t.
I DON't want to take into account timezones and daylight savings, so the input date must be converted into the exact output date.
So, i've avoided mktime() to convert from tm (filled up with string dates from source) to time_t.
The next solution i've used was to convert a SYSTEMTIME to a time_t with these functions (based on similar functions, UnixTimeToSystemTime(), described in MSDN):
void FileTimeToUnixTime(LPFILETIME pft, time_t *t)
{
LONGLONG ll;
ll = pft->dwHighDateTime;
ll <<= 32;
ll |= pft->dwLowDateTime;
ll = ll - 116444736000000000;
*t = ll / 10000000;
}
void SystemTimeToUnixTime(LPSYSTEMTIME pst, time_t *t)
{
FILETIME ft;
SystemTimeToFileTime(pst, &ft);
FileTimeToUnixTime(&ft, t);
}
because I was sure that SystemTimeToFileTime() only converts to SYSTEMTIME format to FILETIME format without any other considerations like timezone or daylight saving.
In my PC these work well. When I've run the code in another PC, the resulting date is 1 hour back.
(it's very strange too, because that PC has the same date settings of mine).
I can't achive the result to obatin a time_t that reflect the same source date, without variations caused by currently timezone and daylight saving settings.

Input file is a CSV file. Dates are in dd/mm/yyyy format and I've to convert those dates into time_t without time zone o daylight saving affection ...
