Hi Friends,
I have CRichEditCtrl in my appln.
I want to chang the text selection color to Red(default is BLACK).
Any one have any idea? 
Thanks

I think CRichEditCtrl::SetSelectionCharFormat() is the closest
you're going to get.
I don't see any specific message to set the default selection colors.

I have an MDI application using the MFC feature pack which has several dockable views. A couple of these views really need their width keeping above a certain size or else they become a bit pointless because you can't see anything on them which could confuse the less mentally agile of users.
I've tried setting the m_sizeMin variable in the CDockablePane derived view class but that only works in certain circumstances. When you dock with tabs and certain other situations it seems to get overridden. Is there a blindingly obvious way to do this that I'm missing?

This is what i did till now..
CTime currentTime=CTime::GetCurrentTime();
int nDay = currentTime.GetDay();
int nMonth = currentTime.GetMonth();
int nYear = currentTime.GetYear();
int nHour = currentTime.GetHour();
int nMin = currentTime.GetMinute();
int nSec = currentTime.GetSecond();
currentTime -= 2592000; ///30*24*60*60 (Seconds)
nDay = currentTime.GetDay();
nMonth = currentTime.GetMonth();
nYear = currentTime.GetYear();
nHour = currentTime.GetHour();
nMin = currentTime.GetMinute();
nSec = currentTime.GetSecond();
But i dont want to calculate it like this. Can anybody suggest me soem other method?

Try this instead:
SYSTEMTIME varTime;
GetSystemTime(&varTime);
varTime.wMonth--;
After the third statement, the month would be decremented by one. Kinda obvious, but you asked for it.
Add: Oops! I haven't taken account of the year January. But I think that you must be able to do it yourself now.

What about if you are on 30th or 31st of march? Or any other 31st where the moth before only 30 has? Won't it crash? :P

BTW, I forgot to mention it won't *Crash* anyways.
SYSTEMTIME is just a structure and it can store the value you put into it. The trouble may come, only when a call to something like SetTime() is called with the new time structure after decrement has happened.

I think the below code will do the trick, anyway verifying it is up to you 
CTime today = CTime::GetCurrentTime();
CTime aMonthAgo;
CTimeSpan ts(today.GetDay(),0,0,0);
aMonthAgo = today - ts;
aMonthAgo += CTimeSpan( - aMonthAgo.GetDay() + today.GetDay(), 0, 0, 0);
[added #1]
That was buggy, forget it  . Anyway are you aware that your requirement cannot be satisfied when current day is for instance March 31th?
[/added #1]
[added #2]
Fixed code:
CTime today = CTime::GetCurrentTime();
CTime aMonthAgo;
CTimeSpan ts( today.GetDay(), 0, 0, 0 );
aMonthAgo = today - ts;
int iSpan = aMonthAgo.GetDay() - today.GetDay();
if (iSpan > 0)
aMonthAgo -= CTimeSpan( iSpan, 0, 0, 0);
This code sets aMonthAgo to:
(1) a date having the same day (of month) of current date, but month equal to previous month, whenever such requirement can be satisfied.
(2) Last day of previous month whenever the requirement (1) cannot be satisfied (for instance when input date is March 31th).

SYSTEMTIME today, lastMonth;
GetLocalTime(&today);
memcpy(&lastMonth, &today, sizeof(SYSTEMTIME));
if (lastMonth.wMonth > 1)
lastMonth.wMonth--;
else
{
lastMonth.wMonth = 12;
lastMonth.wYear--;
}

Quick question - do I lose thhose points for forgetting to consider the question:
What is the date 1 month prior to the 30th of march?
|
|
|
|

That's a flaw of OP's requirements.
The same applies to March 31th (and, for most years, 29th), May 31th,...

If the current date happens to be March 31st and the year is not a leap year, the most days you'd be off is 3. That said, once you subtract 1 from the current month (use the % operator so that it will wrap back around to December as needed), you may also need to subtract up to 3 days to have a valid date.

Hi guy,
does someone know some tricks to increase the time performance
of a VC++ application that need to write a large amount of data
into an Excel Sheet ?
Thanks
|
|
|
|
|
Yup!
Use a multidimensional safearray.
Once upon a time I was filling an Excel sheet with ~10Mb and it took about 40 minutes addressing one cell at a time. With a multidimensional safearray it took ~10 seconds.
