I have to write a C++ code that computes the greatest common divisor of two numbers.
When Declaring x, y, temp, remainder as a Integer is this right? Or can someone help me in the right direction.
int x = 0;<br />
int y = 0;<br />
<br />
if (x < y) then<br />
<br />
cout << temp = x; <br />
cin >> x = y; <br />
cout << y = temp <br />
<br />
if else remainder = x % y

A recursive solution might look like:
int getGCD( int x, int y )
{
if (0 == y)
return x;
else
return getGCD(y, x % y);
}

<br />
int x = 0;<br />
int y = 0;<br />
int A = 0;<br />
int B = 0;<br />
int R = 0;<br />
<br />
Read x and y<br />
<br />
if (x >= y)<br />
{<br />
A = x;<br />
B = y;<br />
}<br />
else<br />
{<br />
A = y;<br />
B = x;<br />
}<br />
<br />
R = (A % B);<br />
<br />
while (R != 0)<br />
{<br />
A = B;<br />
B = R;<br />
R = (A % B);<br />
}<br />
<br />
Report "the GCD of x and y is B"<br />

Hi all,
ColeDateTime m_starttime_ole,m_endtime_ole;
COleDateTimeSpan diff=(m_starttime_ole-m_endtime_ole);
int hour=(int)diff.GetTotalHours();
CString Value;
Value.Format(_T("%d"),hour);
AfxMessageBox(Value);
i m using this to get total hours.
it gives total hours 16,while actual total hours are 8.
please tell me correct way to calculate total hour diffrence between two timings.
please help me for this.
thanks in advance.

Which is correct, since 2/3 of a 24-hour day is ~16 hours.
Now if you really wanted a difference of 8 hours, you need to set m_endtime_ole to be one day after m_starttime_ole. As it stands, they are the same day.

Hello every body
I've just down loaded visual studio 2008 C++ and is
only supports .NET. Is Microsoft hoping that the MFC with wither
and die.

If they did the same as they did for VC2005, the MFCs are not included in the express edition. You have to buy the standard edition in order to have the MFC's.

That has probably been the case since about 2002/2003. MFC still has a pulse but they have beaten it down pretty hard. We still use it for standalone apps as it has the most flexible structure and you get the sourcecode so you can tweak the MFC code out of tight spots.
If you buy the Professional Edition of Visual Studio 2008 and download the Visual C++ 2008 Feature Pack, you will find MFC has support for some new goodies like Office ribbons and the docking bars have gotten pretty advanced.

How to open excel file in Windows mobile MFC application??
|
|
|
|

I've installed several key-logger on my system one after the other (not at the same time  ). Almost all have worked correctly except one thing!
when the user types something in Microsoft Office programs like MS Word, each single character is registerd several times in the log file! for example if the user has typed the word "Hello World!", it's registered as "HHHHHeeeeellllllllllooooo WWWWWooooorrrrrlllllddddd!!!!!". I've already tried to design my own key-logger! but the same problem occured.
Thank you masters!

This is a stab in the dark, but I'm guessing by key logger you mean a keyboard hook, and that you are reporting both WM_KEYDOWN AND WM_KEYUP.
Iain.

Yes, I meant Keyboard Hooks, and at least in my own app, I'm sure I was processing ONLY WM_KEYDOWN.
Thank you masters!

I want to know how to determine if the user is connected to the Internet or not. But I have a limitation, that's I MUST use pure Win32/64 API only. any help?
Thank you masters!

Try InternetCheckConnection[^] from the WinInet API. InternetAttemptConnect[^] might also serve you.

hi!
i want a sample for USB working, sending and recieving data to USB port
thank you

Working with a USB is not like working with a serial port. You can't simply open the port and read/write data. Instead you have to get a handle from a device driver that is supplied with the device you want to communicate to.
So in brief, you never access the port directly but a driver and you never 'know' that you in fact access the USB port through the driver. You simply communicate with a driver. To get the handle, you have to use CreateFile and once you have the handle, you can write or read data using WriteFile/ReadFile. You can exchange driver specific information using DeviceIOControl.
All of these things are very specific to the driver (and device) you are accessing. So, if you want to information, you will need to be much more specific and tell us which device you want to access.

for example, an USB hard lock.

On Cedric's behalf:
You need to read his message again - look at the website for the supplier of the hard lock (whatever that is). Usb is NOT like the serial port, you talk via device drivers. So you need the information from the supplier of whatever the device is.
Iain.
