How to save the scene of a process and restore the process to the scene later(in Windows XP) - C / C++ / MFC Discussion Boards

Hello all,

I'm new in programming client-server applications. I'm using Remote Procedure Call (RPC) to do that.
I tried a small demo and it works fine when I call server-side functions from the client. But the problem comes when I tried to call client-side functions from the server.

Can anyone help me or give me links to articles talking about this issue?

Thanks a lot.

I can't find what I'm looking forward.
I want to know how can the server send data to client.

Thanks

Dear all,
Please explain me how to save recurring items into outlook.
I'm using Microsoft Outlook 9.0 object library.
There is a class AppointmentItem and with a exposed function GetRecurrencePattern() for retreiving. Like wise, no SetRecurrencePattern() method is availlable.

Please guide me how to save a RecurrencePattern object for an appointment item.

Thanks in advance,
Raja Pratap K.

To convert a long to a string, you can use sprintf (print formated data to a string) or ltoa[^]

How to save the scene of a process and restore the process to the scene later(in Windows XP)

I want to save the scene of a process to the disk so I can restore the process to the scene later.

1. How to save the scene to the disk? I think if to save the scene to the disk, I must write the whole process address space to the disk. Is that realizable? Or there is more effective way to save the scene?

2. If the scene of the process had been saved to the disk, is there any way to restore the process to the scene?

---- thanks and over

Hi,

In my program I have some data as a const BYTE* called lpData. However I need to covert this to an LPCSTR. How can I do this?

Thanks in advance

an LPCSTR is already a pointer to Ansi C-style string, so, a pointer to a BYTEs array...

just cast.

To find radius of a circle

Hi Friends,

I am working on one Image processing application where I am capturing the Image of the circular object and by edge detection I am getting the periphery of that circular object.

Now I want to find out the radius of the same circular object, can any body guide me how to find the radius of the circle.

Regards,
Dinesh.

this is more a math question.

if you know the periphery length (let's call it P), then you can do this :

P = 2 * pi * r
r = P / ( 2 * pi)

with r beeing your radius

Unlike tox, with that I understand that you have access to the points representing the circle on the screen. If you really have the periphery length, then have a look at his post.

If you have "captured" a set of points defining the circle, simply look for min and max coordinates in each direction (let's call them xmin,xmax,ymin and ymax), then :

radius = (xmax - xmin)/2 or = (ymax - ymin)/2 (both values should be the same).

center point of the circle is (xmin + radius, ymin +radius), for instance.

CSocket Bind Invalid Argument Error

I am trying to create a UDP connection using the CSocket class. The code I have so far is this:

<br />
CSocket	sock;<br />
<br />
//Create socket<br />
	if (!sock.Create(0, SOCK_DGRAM, NULL))<br />
	{<br />
<br />
		GetSocketError();			//Get Socket's Last Error<br />
		return -1;<br />
<br />
	} //__if (!sock.Create(...))__<br />
<br />
<br />
//Bind socket<br />
	if(!sock.Bind((UINT)4200, _T("127.0.0.1")))<br />
	{<br />
		<br />
		GetSocketError();			//Get Socket's Last Error<br />
		return -1;		<br />
		<br />
	} //__if(sock.Bind(...))__<br />
<br />
<br />

The call to Create() works without a problem but when I try to bind to the port and address I get an "Invalid Argument (10022)" error.

Any suggestions?

Thanks.

Yes... it's an "Invalid Argument" error:

WSAEINVAL
(10022)
Invalid argument.
Some invalid argument was supplied (for example, specifying an invalid level to the
setsockopt function). In some instances, it also refers to the current state of the socket - for
instance, calling accept on a socket that is not listening.

why dont you try with NULL as the second parameter?
