Thats what We (i.e. I) call Right attitude... But thing that worry why the hell you people worry about the Voting system... we know you are helping other people.. My personnel advice is that leave that 1 vote or five vote matter. i believe you remember this famouse SLOKE (Idiom) from Bhagwat Geeta

I agree I think that since you can anoyn rate articles and posts people just get upset or childish with other people and vote down for no reason. I suggested two years ago that article ratings at least should require that the user enter a comment as to why they rated the way they did so now there's more accountability when making a rating. Perhaps there should be one where you have to reply in order to rate a post even or be the one who asked it.
You could also have 2 ratings, the anon rating and the known rating where the anon rating is taken with a grain of salt.

I would nix the extra thread and focus my attention on getting the server/client communication working. Then, and only then, should you attempt to add the complexity of additional threads.

communication is proper.. one thing is when client is disconnected i should get "client disconnected". particular number of client can be connected.....so when one client disconnect then it should be intimated and its IP address should not display on server..
no need for additional threads i think..
as i said i'm sorry i'm new to this area.

Hi,
There
In my project(Visual C++ project, there is a Editbox in a form,
I would like to copy a segment of selected text in the Editbox into clipboard by pressing Ctrl-C as we would with MS-Word. I wonder if this is possible, and how to achieve this.
Thanks

if you have a CEdit (MFC) and select a part of the edit content, then Ctrl+C will automatically copy the selection into the clipboard...

Tox, you were right to have posted that message. Even I wondered why had you went to that level down, but I too am Feeling the same. There is somebody who is giving EVERYBODY a low rating (whenever they get 5). I do not understand why someone would do this. But it HURTS MAN. Believe me. It hurts a lot. You take your time to analyse the problem, and then you give the best possible solution that you can. The one who asked the question thanks you and gives a 5, so does some people... After some time, the rating comes down for no reason. I think rating must be given by the person who asks the question or whomever is involved in the conversation only. It hurts. Or just remove this rating thing. We are ready to help for no rating. Not a problem. I could understand what Toxcct felt, now. It hurts man. I have joined CP recently and started helping ppl very recently. Why would someone have a problem when I get a 5 rating? I know I have to use profanity and behave myself in this forum, with a bundle of real genius people...
If this is wrong too, i will delete this. Not a problem. I will keep to contribute whatever I know, no matter if it is a penny or two. If it helps someone, I am happy. Give me zero rating, I dont care until the person gets helped and tells me that.

What does all of this have to do with Ctrl+C and the clipboard?
Quite worrying so much about votes. They're next to meaningless in my opinion. Never understood why people get so hung up on such unimportant things. At the end of the day, it doesn't matter.

Thanks for the concern David, I have understood it is meaningless. really. I continue to contribute as much as possible without worrying about votes and all that stuff.

Rajesh,
You said "I know I have to use profanity and behave myself in this forum".
Personally, I don't object to a little profanity from time to time, but others might.
I offer you the best possible vote.

Thank you so much for your reply.
In my project, I cannot use CEdit class. I have to use CFormView class and EditBox control.
Do you mean that it is impossible to use Ctrl-C to copy a segment of selected text to clipboard in my case.

Hi,
I require high precision data types in order to store fractional values up to say around 64 decimal places (arbitrary would be good also), i.e. 0.999999991228342783642783647826347263487234... etc. The double datatype is insufficient, and the long double is double in disguise by current compiler standards (why this is so I'm not sure). So to overcome this problem I serched the internet high and low for a C++ class based high precision data-type and found, amongst others, QD (quad-double) which would be fine for my purposes. (you can find this on a goodle search)
When I set up a standard console application and then try to include all the files everything works fine and everything links, so long as i add the qd progect to my solution and alter program dependencies so that my main app depends on the qd vcproject. The program quite happily churns out high precision results using the "qd_real" data type class.
However, if i try to get the same class to work in an MFC console application it doesnt want to play. At build time I get very strange results such as:
c:\Documents and Settings\Paul\Desktop\HP\qd-win-2.1.48b\qd-win-2.1.48\include\qd\qd.h(258): error C2059: syntax error : ')'
c:\Documents and Settings\Paul\Desktop\HP\qd-win-2.1.48b\qd-win-2.1.48\include\qd\qd.h(151): error C2059: syntax error : 'newline'
c:\Documents and Settings\Paul\Desktop\HP\qd-win-2.1.48b\qd-win-2.1.48\include\qd\qd_inline.h(49): error C2065: 'a' : undeclared identifier
c:\Documents and Settings\Paul\Desktop\HP\qd-win-2.1.48b\qd-win-2.1.48\include\qd\qd_inline.h(54): error C2084: function 'qd_real::qd_real(int)'
already has a body
c:\Documents and Settings\Paul\Desktop\HP\qd-win-2.1.48b\qd-win-2.1.48\include\qd\qd.h(258): error C2143: syntax error : missing ')' before ';'
These errors didn't occur in the standard console implementation.
Furthermore, if I take the #include "qd/qd.h" and put it before the #incude "stdafx.h" the application compiles, but then the program complains that it doesn't know what qd_real class is if i try to instantiate one in main().
I've also tried placing the #inlcude "qd/qd.h" in the stdafx.h files, but still it comes up with the errors.
Does anybody have some sort of idea what is going on?
Thanks.
Paul

I dont know where you got that version from - I couldnt find it, and the one previous to that, is a unix build environment and its very late at night down here, so 'scuse me for not building a library from it ...
- there's a 'windows' version here :-
http://www.cs.berkeley.edu/~yozo/[^]
(look for qd-win-2.1.19.zip)
this may improve things ... (my suggestion would have been to build qd as a seperate library, hopefully the win version does this and its more use)
