Yes (and it possibly returns 09034 for your input).

You can roll your own one. What are your doubts while doing that?

I recall for you the needed steps (if you aren't using MFC or ATL). You have to:

Parse the string to obtain day-of-month, month and year from the string.
Convert day-of-month and month to day-of-year.
Align properly year and day-of-year values in the resulting number.

In the above task, only point(2) is a bit tricky because of leap years.

Using MFC or ATL would make your life easier.

just use scansf grab the constituent parts and throw it into a SYSTEMTIME struct.

Just rember that scanf assumes int * and the systemtime struct is all word size objects.

DWORD Month,Day,Year,Hour,Minute,Second;

//Initalize the values and the structure to zero
Month = Day = Year = Hour = Minute = Second = 0;
memset(&ST,0,sizeof(ST));
//Fix This use the stram reader so I can read the write size
//Parse out the date with sscanf
sscanf_s(Val.c_str(),"%d/%d/%d %d:%d:%d ",&Day,&Month,&Year,&Hour,&Minute,
&Second);

//reassign the values into the structure
ST.wDay = (WORD) Day ;
ST.wMonth = (WORD) Month ;
ST.wYear = (WORD) Year ;
ST.wHour = (WORD) Hour ;
ST.wSecond = (WORD) Second;
ST.wMinute = (WORD) Minute;

it depends on what you mean by julian date - since the term is most often miss-used these days.

If you mean 'the day number as a number starting counting from the 1st of Jan in the Current year', then you need to follow the advice of our trusted and esteemed colleague CPallini

If you mean since an arbitrary point in time - such as is used by astronomers etc, ie 4713BC, then, part one of CPallini's response still applies, then you feed the results of the parse into something like :-

Use SendMessage to send the EM_SETBKGNDCOLOR message to the rich edit control.
Look at the documentation for EM_SETBKGNDCOLOR on how this is done.

How to access product version of an MFC application programmatically?

I suppose (it's just a guess, however) you simply cannot do that.

Hai!

In the Resource view of my application there are folders such as Dialog, String table, Icon, Version. If i click the version a window appears which contains the updated values of file version and product version etc.
How can i programmatically get this value of product version as i need it to display in an AfxMessageBox. Is there any function to access this value of Product version.

Thanks!

Hi,

I have been posting messages re: WIN32 C app my last few question have been regarding Calculating the number of characters in the edit control of a Rich Edit Dialog Box

All of the really nice pepole here have been sending me code snipts to help me out however most of the Code was of the MFC variety

In order to get with the program I decided to re-write my C app using the MFC classes as opposed to plain old WIN32 SDK api's

So now getting back to My orignal Problem I have been using WM_SETTEXT and EM_REPLACSEL meesages to highlight certian pieces of the Dialog Box

Now that I am using the methods to the base Class CDialog

seems using the DDX macros is the way transfer data as opposed to

WM_SETTEXT and WM_GETTEXT

will DDX still work To HighlIght data using EM_RELACESEL ????

thankx Again
