Is there a Win32 API for parsing a string that represents a date/time value and getting back a SYSTEMTIME or something similar?
I found VarDateFromStr but I notice that it appears to cause access violations on certain unpatched systems, so I'm reluctant to use it.

Did a bunch of research on this, back in July, and VarDateFromStr is the best I could come up with.
For the VCF:
DateTime Win32LocalePeer::toDateTime( const UnicodeString& str )
{
DateTime time;
DATE dtSrc;
unsigned short* data = (unsigned short*)str.data();
HRESULT hr = ::VarDateFromStr(data, LANG_USER_DEFAULT, 0, &dtSrc);
if (SUCCEEDED( hr ))
{
struct tm newTime;
SYSTEMTIME st;
if( VariantTimeToSystemTime(dtSrc, &st) )
{
newTime.tm_sec = st.wSecond;
newTime.tm_min = st.wMinute;
newTime.tm_hour = st.wHour;
newTime.tm_mday = st.wDay;
newTime.tm_mon = st.wMonth;
newTime.tm_year = st.wYear;
newTime.tm_wday = st.wDayOfWeek;
newTime.tm_isdst = -1; // Force DST checking
mktime(&newTime); // Normalize
time.set(newTime.tm_year, newTime.tm_mon, newTime.tm_mday, newTime.tm_hour, newTime.tm_min, newTime.tm_sec);
}
}
return time;
}
Haven't run into any problems with it in production code (yet!), but will keep my eye out for any access violations.

Steve, are you using the VCF? In production code? That's awesome!

Using the VCF and loving it! Had to make a few modifications, but so far it's working great! I guess I use the term "production" a bit loosely, as it's still very much in beta, and only a few people have downloaded it. 
This is sort of my VCF pet project (still got a ways to go...):

Holy crap that's totally cool! You should post something on the VCF boards! If you can't or don't have the time, do you mind if I do?
Do you know of anyone else using it? I had no idea about this!!

Sweet! Thanks, and thanks for the VCF! It rocks! 
I was going to post some screen shots on the VCF forums, but got side tracked, so you're more than welcome to do that if you'd like.
The only people I know who are using it are a few of my slacker friends and a couple of relatives. I'm trying to get them to beta test it, but they're, ummm, slackers.

Greetings Good People,
I am trying to get my "Output" control (i.e. similar to the Visual Stuido output window at the bottom) to show at the top of the MainFrame. I gave it the style CBRS_TOP (of course), for it to display at the top. However, when I run the software, I noticed that it is momentarily placed on the top until the ChildFrame pushes it to the bottom once it is dispalyed. How do I get the ChildFrame to behave and display underneath the "Output" control? Also, is there an easy way to arrange my controls so that I can place two on the left (i.e. each taking up half the space), one big one in the middle underneath a smaller control, and possibly another one on the right?
Any help or pointing to a resource that helps answer my question would be greatly appreciated.
Thanks,
BP

I am writing a POS (point of sale) type application. How do I cut short through all the MFC pallaver about formatting, and output say 80 colum text onto a generic dot matrix printer.
-
Location of Printer, and capabilities of printer to be found
either in Registry, or in an INI type file. Definitely NO choice by user of any features, such as choice or printing format!
-
Only four possible error contitions: ERR_PRINTERNOT_FOUND, ERR_PRINTER_NO_PAPER, ERR_PRINTER_NO_INK, ERR_PRINTER_MECHANICAL_FAILURE.
regards

I would like to know if MS Visual C++ is able to select the variables within a project that would be able to be monitored and logged into a file for each step?
For e.g. if I wanted to monitor a number of variables with in a for loop over the multiple iterations of the loop, would it be possible for me to view some selected variables and get the MS Visual C++ debugger to store the values in a text document?

I don't think it can... you could just add a little code to do it yourself though.

Yes,
Standard Debugging Methods:-
Depending on whether you are a beginner or advanced user, the answer to your question is either simple or complicated. I asume for now that you are a beginner! Because your question touches on many issues beginners face, I will try and formulate an answer,.-
The question is: How do I monitor what's happening. The old adage used to be: "When in doubt, print more out". The general idea is, write a few macro's which at time of debug dump variables and line numbers etc to a file, and make sure that the self same macro's resolve to ((void)0) at release.
-Write code that dumps variable valies to a file
-use Conditional code to call int3's (User Breakpoints)
-set conditional breakpoints in your file(s)

i use vs.net2003.as soon as i start debug,the usage of cpu is up to 100%.especially the thread devenv.exe take a lots, about more than 90%.
give me a help!
thanks a lot!

Ahh >_< lack of space. Anyways, not having VS .NET 2003 i don't know, but im assuming that devenv.exe is part of it?
Anyway, since this happened, have you tried restarting your computer? It could just be some wierd problem. Also try debuging a different app that you have available to see if it still steals all your CPU, it may be something to do with your application.
Or it could be Some kinda spywary virusy type thing.
I have stop sign, and at one point one of the 32KB exe's was taking up 190MB of RAM, whats up with that? In the end i had to re-install.

Your sig doesn't show up right to me (i think).. i am using firefox, all i see if a big blue rectangle and a few lines.
I don't believe in failure. It is not failure if you enjoyed the process.
|
|
|
|
|
I think these styles are limited to IE because on Opera and (Firefox) I cant see any thing maybe I must modify my sig
|
|

What happens if you just run your app ? Could your app be maxing out the CPU ?
devenv.exe is the IDE. It could even still be compiling, and you're jsut freaking out. What happens if you let it do it's thing for a while ?

i have restarted computer,but it still is.
what's more ,i also build a new project,the cpu's usage is the same!

Perhaps if you took the time to answer the questions people have put to you, we could help more.

Maybe you are in the wrong forum, but you posed it to a VCPP, MFC forum anyways, so here she goes. The basics of this are ASM Debugging Techniques:-
Sometimes things like that happen when writing MFC Code. It nearly always means that I landed in an infinitely recursing set of functions.
To unravell this, Start with writing a macro that documents and dumps ESP to a text File.
Then, prepare to spend a few days at it, setting breakpoints, and tracing manually to the problem. Keep a sheet of paper beside you to write down calling addresses, and, depending on the complexity of your code, the repeating feature of calling points will soon give you an idea where the problem is.

Its first time you have this problem or no?

Ok!
thanks all of you! especially MVP~
when i add "/devenv/skippkgs" to the compiler;
then the computer runs as normal.
i don't know why!
nice

If you do not now spend some time to find out the 'why' you have bot learned anything. Please let us know.
