Re: Convert Custom String in to Date Format (mmmm dd, yyyy)

21-Jul-05 20:52

Hi.. All
I m Working on one of Text-correction module ..
I have some difficulty in conversion of the various form of Date come in to raw-input text to some Standard format(mmmm dd yyyy).

various possibilty of Date text are:
input OutPut
Jan 5th 2005 = January 5, 2005
Jan 2605 = January 26, 2005
Jan of 05 = January 2005
Jan 05 = January 2005
6th of June = June 6, 2005 or June 6
6th of June 05= June 6, 2005
this month 6th = July 6, 2005
On 6th of this month = June 6, 2005

or only number like max-digit(i.e: 06242005) = output Reqired is : mm/dd/yyyy =06/24/2005
to min-digit (i.e : 625) = = output Reqired is : mm/dd/yyyy =06/2/2005

Can any one Guide me ... how I can Do...it..
I m very much confused ?? for the logic....
can any MFC class help here ? CDateTime , CDateTimeFormatInfo ????

pls...Help me ... looking for positive reply form all of u !

thanks in Advance !!

Thanks for u r Reply...
But I have clearly mention that ... My problem is Parsing the "ambigous" String not the Formating the Date. If I can find the Proper input the Any Constructer of MFC class (like , COLEDateTime, CDateTime , CDateTimeFormatINfo,,... ) then I can Convert to any format of date!!
But My Problem is how to find parse the input Nummeric??

i.e: only number like max-digit(i.e: 06242005) = output Reqired is : mm/dd/yyyy =06/24/2005 to min-digit (i.e : 625) = = output Reqired is : mm/dd/yyyy =06/2/2005.

Can u help me for this ???

Have a look at COleDateTime class as well.

Break the inputs down into what they are/aren't like:

if (first_3_letters_are_a_month)
{
    Jan 5th 2005 = January 5, 2005
    Jan 2605 = January 26, 2005
    Jan of 05 = January 2005
    Jan 05 = January 2005
}
else
{
    if (first_word_is_this)
        this month 6th = July 6, 2005
    else if (first_word_is_on)
        On 6th of this month = June 6, 2005
    else // must start with a number
    {
        if (first_word_has_th)
        {
            6th of June = June 6, 2005 or June 6
            6th of June 05= June 6, 2005
        }
        else
        {
            06242005 = 06/24/2005
            625 = 06/2/2005
        }
    }
}

Now you should have an easier time parsing them.

Thanks for u r Reply sir.

But ..still here my patterns are not static ( u assumed by mistake ) my patterns may vary due to human tendecies to speck every time different patterns for the same thing !! so.....I can't make the code based on pre-assumption like u !!

Currently , I m doing the Ambigious rule making for the Text-correction..
But , I m still confused at parsing the only Numbers string ( how to differnceate with numbers for Day,Month,Year...! Can i make Regular Expression to validate the input numbers in to Day, Month, Year?

Can u assist me ?

How about:

CString strDate;
if (strDate.GetLength() == 8) // e.g., 06242005
{
    nMonth = atoi(strDate.Left(2));
    nDay = atoi(strDate.Mid(2, 2));
    nYear = atoi(strDate.Right(4));
}
else if (strDate.GetLength() == 3) // e.g., 625
{
    nMonth = atoi(strDate.Left(1));
    nDay = atoi(strDate.Mid(1, 1));
    nYear = atoi(strDate.Right(1)); // might want to add 2000
}

Thanks for u r reply....
I have done same thing ... just 2-day before... I have written various RE for classifying Input String in to DATE Formats based on it length.

one of possible RE u can see : for 8-digit string :
((^(?<month>10|12|0?[13578])(?<day>3[01]|[12][0-9]|0?[1-9])(?<year>(1[8-9]\\d{2})|([2-9]\\d{3}))$)|(^(?<month>11|0?[469])(?<day>30|[12][0-9]|0?[1-9])(?<year>(1[8-9]\\d{2})|([2-9]\\d{3}))$)|(^(?<month>0?2)(?<day>2[0-8]|1[0-9]|0?[1-9])(?<year>(1[8-9]\\d{2})|([2-9]\\d{3}))$)|(^(?<month>0?2)(?<day>29)(?<year>[2468][048]00)$)|(^(?<month>0?2)(?<day>29)(?<year>[3579][26]00)$)|(^(?<month>0?2)(?<day>29)(?<year>[1][89][0][48])$)|(^(?<month>0?2)(?<day>29)(?<year>[2-9][0-9][0][48])$)|(^(?<month>0?2)(?<day>29)(?<year>[1][89][2468][048])$)|(^(?<month>0?2)(?<day>29)(?<year>[2-9][0-9][2468][048])$)|(^(?<month>0?2)(?<day>29)(?<year>[1][89][13579][26])$)|(^(?<month>0?2)(?<day>29)(?<year>[2-9][0-9][13579][26])$))

This way I have solved my proble ......is it write-way to do it ???

and I want to ask? how to parse the Unkown or Ambigous pattern ....like ?
"on 10th of this month" ----> so I want to find the current system date whenever I found word "this" !!!! is It?? Can I do similar for "next", "previous" ...words???? and for Day,Month,Year ??

can u assist in this similar type of problem ???

My first response would be no. Since there are only six possibilities, using an if/else construct would be much simpler now and in the future if you or someone else needed to modify it.

This is a very strange looking sentence, but I think what you are asking looks like this:

if (3 == length)
else if (4 == length)
else if (5 == length)
else if (6 == length)
else if (7 == length)
else if (8 == length)

If that is not right, please ask again.

Like I indicated, today's date can be obtained using time(). Yesterday's date can be obtained by subtracting 86400 from that value, and tomorrow's date can be obtained by adding 86400 to that value. Make sense?

its good to see u that we r thinking same way...!! Blush | :O

For Only Number- parsing last time I have written , that I have written various Regular-Expression (RE) to parse the given length number in case statment !!! ( one of Example of RE for stringlen(8) I have given last time )

In Last Reply I have asked a'bt how to tekal words like : "this Month" , "this year", "Next Month","Next Year", "Previous Month", "Previous Year", Etc...

Currently I m thinking in a way that, I m Extracting DAY,MONTH,YEAR from the given pattern and then I search for words (this, next, Previous)tide with DAY,MONTH,YEAR word and then from Current system date Extratcion of current DAY, MONTH , YEAR......I m incrementing (+1) or decremanting (-1) by one to corresponding DAY,MONTH,YEAR variable . But,conflict for "next " phares is when we r in Decemeber and "next month " phares occurs then we increment Year and set month to January ......similar problem for "Previous" phares at January month ...? Frown | :(

(( ........
Is It I m going right way in my path ? Confused | :confused:

or .....any other good Idea Cool | :cool:

??

wait for u positive reply and then start implementing this Idea.....

This is how I did it some eleven years ago. But since MFC has four date-related classes (I'm not sure if STL does or not), I would use them instead. There's no need to reinvent the wheel.

I m not Understanding ..? can u Explain me in Deep??

As Mention preiously that how i can code perticular Pattern like this :::
" Next year 10th of January " ------> "Next Year [Day](th)* (of) [Month]" (I m parsing using this rule) and initilize the DataTime strucure with parsed Day,Month and missing term Year with Current System Year with (+/-) corresponding to words like " previous, next, this" phrases.

Replacement pattern is : [Month] [Day], [CurrentSystemYear]

can I stic to this type of staic parsing ? Sleepy | :zzz:

Is it write way to do it ? Confused | :confused:

Waits for u r reply!! Big Grin | :-D

Instead of doing this:

void IncrementDay( int &nMonth, int &nDay, int &nYear )
{
    nDay++;
    if (nDay > DaysInMonth(nMonth, nYear))
    {
        nDay = 1;

        nMonth++;
        if (nMonth > 12)
        {
            nMonth = 1;
            nYear++;
        }
    }
}

Do something like this instead:

CTime today = CTime::GetCurrentTime();
CTimeSpan oneDay(1, 0, 0, 0);
CTime tomorrow = today + oneDay;
CTime yesterday = today - oneDay;

Simpler?

this one is simpler ....but how to takel with Month & Year ....increment ....No constructor for which give us month and year initilization.( we can't sent timeticks also ....i.e 30|31 * oneDaytime or 365|366 * onedaytime )
How i can Do increment & decremant Month & Year Now from U r Way ! U make me more confuse by giveing this idea! Laugh | :laugh:

also, how u think a'bt my Search-Replace Rule Idea ? Roll eyes | :rolleyes:

By knowing how many days are in each month. If today is July 27th, 2005 and I wanted to advance one month, use:

CTime today = CTime::GetCurrentTime();<br />
CTimeSpan oneMonth(31, 0, 0, 0);<br />
CTime nextMonth = today + oneMonth;

Hi all,
I have a program that contains a Server and a Client app.
I want my server app to this:
When I installed my server app it would automatically install the client app
on the all computers in the network.
I mean:
Installing a file on a computer in a network without having a client program!
It's very important,
Cheers,
Thanks,

So the server will contain the client app, and will farm it out to all clients on it's network ? Sounds very viral to me. Can you be sure that your server will have the right to perform this action on all clients ? The easiest way would be to copy an installer onto the client machine, and put it's path in the runonce registry key so it installs on the next startup.
