Can someone steer me in right direction to come up with three commands to switch the x and y with remainder and then recalculate the remainder.

As enhzflep says, I have no idea what you're typing about. Try giving examples of what you're trying to do, with real numbers?
If you want people to read your question, think abour the problem, and then assist you with a solution, you need to put some more meat in your question to start with. You're not paying people here, so you need to catch their interest.
Also, please read the posting guidelines. "Help please" is not a very good title. Do you think all those people with useful titles without the word "help" don't want help?

Are you implementing the Euclidean Algorithm [^]?

I already answered this one for him under "Need help with code" in this forum (Nov 8). Guess he doesn't read very well.

I have a problem regarding DLLs.
We can load a DLL dynamically by using Load Library() function and then we can access the functions of DLL by using GetProcAddress().
But how to Import a class from DLL.
Here actually i want to import a class in my application from a DLL called nnotes.dll ( its a lotus notes DLL). I can see the classes exist in that DLL thru dependency walker. But i don't no the way to achieve it.
Please any body solve my problem...

Hi Hamid,
Thanks for your reply. But still i have problem.
In the exaple what you told, we are the one who created DLLs.
But i need to access classes from a DLL which is not built by me.
basically requirement is am building an application for lotus notes
which is used to work mail level. the minimum requirement for my
application to run is few lotus DLL. If i link these DLLs statically i can
do whatever i want But i want to know the dynamic linking for this.
can you help me in that way.
And really thanks for your response. Because of that i came to know about how
to export/import classes from DLLs which we are going to create.
Thanking you.

Hamid has pointed you to a good article - but it doesn't deal with "run time linking" of objects.
This is not a trivial subject, and is a significant part of the reason COM was invented.
In my software, I go a COM-similar way. I have a base class in a H file, with all-pure-virtual methods. I also have a "get me an object of CXXXX type please" C exportable function exported by the DLL. Inside the DLL I have a CImplementXXXX class that I create an instance of and return.
All very COM/CoCreateInstance. All I'm missing is GUIDs.
As to your problem...
Can you solve it by brute force? Writing a second DLL that compile time links to this class (using the approach in the article), and provides a mechannism like I describe above to create an interface to a proxy object within your DLL?
I'm running out of steam, so I'll wish you well.
Iain.

An example of the Iain's COM-like technique here [^].

I'm now a The? Oooo.
It's a good article you point to - though I think the hack to allow you to access the member functions is a bit too hard and prone to dumb coder mistakes (like I regularly make) for my liking!
It may help him in his reuse of a DLL I bet he has no code access to...

Can someone explain to me how to make a remainder equal the equation for remainder using x and y.
|
|
|
|
|
Sounds like you're after the modulus operator. - %
Code
int x=10, y=7;
printf("x/y = %d, remainder %d\n", x/y, x%y);
Output
x/y = 1, remainder 3

I have a problem with getting message WM_INPUT for rawinput in MFC. There is no such problem in Win32.
Here is my code.....
My message map:
BEGIN_MESSAGE_MAP(CCEREC_MCDlg, CDialog)
ON_WM_SYSCOMMAND()
ON_WM_PAINT()
ON_WM_QUERYDRAGICON()
//}}AFX_MSG_MAP
ON_MESSAGE(WM_INPUT, GetRawData)
END_MESSAGE_MAP()
In header:
afx_msg LRESULT GetRawData(WPARAM wParam, LPARAM lParam);
Register raw device:
BOOL CCEREC_MCDlg::InitRawDevices(void)
{
Rid.usUsagePage = 0x01;
Rid.usUsage = 0x06; //for keyboard;
Rid.dwFlags = 0;
Rid.hwndTarget = 0;
if (RegisterRawInputDevices(&Rid, 1, sizeof(Rid)) == FALSE)
return false;
else
return true;
}
Function:
LRESULT CCEREC_MCDlg::GetRawData(WPARAM wParam, LPARAM lParam)
{
return 0;
}

When I press buttons WN_INPUT is not generated. I also tried with mouse and gamepad.
When I use Win32 all work perfectly but I need solution for MFC.

How does the system know to send the message to your dialog?
Shouldn't you specify the dialog's HWND there?
I bet the control with focus is receiving the message fine

From MSDN
hwndTarget
Handle to the target window. If NULL it follows the keyboard focus.
No Mark, It doesn't work whether or not dialog in focus.

Right.
You're handling the message in the dialog, which
doesn't get keyboard focus.
Maybe use the dialog window's HWND...
Call the CCEREC_MCDlg::InitRawDevices function from OnInitDialog
(it won't work called from the constructor - you need a valid HWND!).
Then use:
Rid.hwndTarget = *this;
