Hi, everyone!
When using the following piece of codes to get the hour value of
the day, I find the value I can get is always 8 hours lower than current time.
I do not know why. Can anyone help?
--------
#include <iostream>
#include <time.h>
using namespace std;
int main()
{
time_t curr_time;
time (&curr_time);
struct tm *curr_tm=gmtime (&curr_time);
cout << curr_tm->tm_hour << endl; //not correct
cout << (curr_tm->tm_hour + 8) % 24 << endl; //not correct
return 1;
}
--------
Thanks in advance,
George

Is your TZ set correctly?

How to check the setup of Time Zone?
I am not in U.S.

Right-click on the time in the icon tray and select Adjust Date/Time. Click on the Time Zone tab. Yours is probably correct since localtime() is working for you.

I want to know if I use gmtime to get GMT time,
how can I correctly change it to correct localtime?
Are there some sample codes I can make a reference?

Your method works perfect. But why gmtime is wrong?

gmtime gives Greenwich Mean Time and your timezone is
8 hours off that.

Since they both operate on the value returned from time(), why not just pass that same value to localtime()? Something like:
struct tm *tm1, *tm2;<br />
time_t _time;<br />
<br />
time(&_time );<br />
tm1 = gmtime(&_time); <br />
tm2 = localtime(&_time);

How to get the information of time zone? I just want to know how
to calcualte locatime from gmtime. 
Can you show me an example?

Use GetTimeZoneInformation().
|

Thanks, DavidCrow buddy!
I have taken some time to read the docuement about this
function. And I really get some ideas about daylight saving
time and stardard time.
But I do not find an example about how to compute localtime
from gmtime, including the consideration about time zone.
Can you show me an example about it?
regards,
George

Have you looked at the members of the TIME_ZONE_INFORMATION structure? It's straight forward math.
For example, I am in CST (GMT -0600) and we are currently in Daylight Saving Time. The members of that structure of interest to me are Bias (360) and DaylightBias (-60). The sum of these (300) added to my local time will produce GMT. So, if it is 0930 right now, adding 300 minutes (5 hours) to that means it is 1430 GMT. Make sense?
get local_time
if (dst)
gmt = local_time + (bias + daylight bias)
else
gmt = local_time + (bias + standard bias)
endif

Hey Friends
I Want To Enumerate (Precisely Get the Handle Of CMDiChild 's )Opened at a Particular Instance.
Help!

What you can do is loop through all of the documents and for each document, loop through all of the open views:
CWinApp *pApp = AfxGetApp();
POSITION pPos = pApp->m_pDocManager->GetFirstDocTemplatePosition();
while (pPos)
{
CDocTemplate *pTemplate = pApp->GetNextDocTemplate(pPos);
if (pTemplate)
{
POSITION pDocPos = pTemplate->GetFirstDocPosition();
while (pDocPos)
{
CDocument *pDoc = pTemplate->GetNextDoc(pDocPos);
if (pDoc)
{
POSITION pViewPos = pDoc->GetFirstViewPosition();
while (pViewPos)
{
CView *pView = pDoc->GetNextView(pViewPos);
if (pView)
{
CFrameWnd* pFrame = pView->GetParentFrame();
... and your code goes here!
}
}
}
}
}
}

I have a Single Doc app and want to put a border around the inside of it.
Thanks,
graham

When drawing inside your client area: 1) Draw your inside boarder, 2) use ExcludeClipRect() to exclude the border area from further drawing, 3) then use the mapping functions set the upper left and lower right courners of the new rectangular area where you wish all your normal drawing to occur, 4) draw like you normaly would.
I recomend you get a copy of "Programming Windows" by Charles Petzold, in order to figure out how to use the mapping functions. Also, try looking at the CDC methods and do a search of the MSDN Library using the names of the functions in the mapping section.
Trust in the code Luke. Yea right!

Hello,
I have a problem with DLLs again 
I have to load two DLLs which each contain 3 functions. The first function has to be called one time, the second very often, and the third only one time.
Now I call the second function about 60000 (each DLL) and I get a stack overflow???
The DLL function is:
DLL_C_EXPORT unsigned long gdPlay(unsigned long uRound, unsigned long uEnemyLast)
{
return (unsigned long)(rand() % 2);
}The calling loop in the main project is:
for(dwRound = 0; dwRound < m_dwRounds; dwRound++)
{
dwCurrent1 = lpDllPlay1(dwRound, dwLast2);
dwCurrent2 = lpDllPlay2(dwRound, dwLast1);
if((dwCurrent1 == 1) && (dwCurrent2 == 1))
{
dwPoints += m_dwPoints11;
}
if((dwCurrent1 == 1) && (dwCurrent2 == 0))
{
dwPoints += m_dwPoints10;
}
if((dwCurrent1 == 0) && (dwCurrent2 == 1))
{
dwPoints += m_dwPoints01;
}
if((dwCurrent1 == 0) && (dwCurrent2 == 0))
{
dwPoints += m_dwPoints00;
}
dwLast1 = dwCurrent1;
dwLast2 = dwCurrent2;
}The DLL is loaded perfectly and it also returns the correct values (I checked it with MessageBoxes)... But after some calls (about 60000 each) there is the stack overflow...
Do you have any idea what could cause the stack overflow??? 
-Dominik
_outp(0x64, 0xAD);
and
__asm mov al, 0xAD __asm out 0x64, al
do the same... but what do they do??

If the calling convention (stdcall etc) isn't correct in the call to the DLL function that might explain it. ie. who is responsible for popping params off of the stack.
