A component of my project is ready, and now i want it to communicate with some administrator(i.e. another component of my project) on the network. But in the beginning, i havn't included the Socket support (while creating new project thro the wizard). How can i add the socket support now and use the CSocket class in my project ...
plz help ...

You need to add following line only,
#include <afxsock.h> br mode="hold" />and before using any socket api, make sure you have called following function(Ideally in Initinstance),
AfxSocketInit();

okay....
i read it ....
but ways the alternative API ... ?
the page give a link to another with a library with its cost !

plz help ...

Use WinSock API (Win32APIs), and write some wrapper classes around SOCKET handle. Use a worker thread to receive data, Parse received data and frame the MESSAGE, which you use to communicate over network.
MESSAGE can be something like...
struct MESSAGE{
int nMsgId; //To describe data
BOOL boolFlag; //Req / Res
BYTE *pData; //Actual Data
//Some more fields depending on your requirement
...
...
};
i think this is enough to start with. You can explore and learn as you progress.

How about CAsyncSocket as an alternative to CSocket? It is better suited for event based applications in my opinion.

Is there any Add-in for Visual Studio to see contents of HDC, HBitmaps, etc. in MFC?
is there any other add in or way to get this functionality?, i found GDI watch but it doesn´t work here.
I need something like that to work on. Thanks

I currently ran into a problem.
It goes like this:
I do some math here
__x=Cam.front.x*tmp*tan(Cam.Tx)+Cam.right.x*tmp*tan(Cam.Ty);
__y=Cam.front.y*tmp*tan(Cam.Tx)+Cam.right.y*tmp*tan(Cam.Ty);
all fine and well .. my 2 variables are what were supposed to be, but when i try to assign them to a structure with more floats , all floats inside ( donno if realy ALL , but looked at some) become -1.#IND000
Anyone knows what could couse this thing ( and a solution wouldnt hurt either  )
Edit:
floats that gets messed up : variables used in expresion ( Cam.front , Cam.right ) and the variable I asign the __x , __y inside the structure ( was Cam.dir)

struct or union?
Please post more code, so that we might be able to help you. Anyway see some blindfold suggestions.
1) Check the watch window for wrong watch expressions. http://www.codeproject.com/Feature/SubtleBugs.aspx?fid=343280&fr=26&select=2542205#xx2542205xx[^]
2) Make sure the optimizations are turned off.
3) Latest Visual Studio service pack installed? (Poor man's bugfix) 
4) Try clean and rebuild. (Poor man's bugfix)

hi,
This is code i am using I've picked it from some where and I've changed it according to my requirements but its not inserting a new record. it gives error like attempt failed or record set is read only. I don't know i am using dynaset as an opening mode but still i get the error. kindly any one knows where i am going wrong.
CDatabase *mydb=new CDatabase;
ASSERT(mydb);
mydb->OpenEx("DSN=ff");
if(!mydb->IsOpen())
{
MessageBox("Unable to connect to Database. Please\ncontact your server administrator.", "Database Error", MB_ICONEXCLAMATION);
return;
}
CRecordset*myrec=new CRecordset(mydb);
ASSERT(myrec);
myrec->Open(CRecordset::dynaset,_T("SELECT s,p FROM e"),CRecordset::noDirtyFieldCheck);
if(!myrec->CanUpdate())
{
MessageBox("Database reports unable to update.", "Database Error", MB_ICONEXCLAMATION);
myrec->Close();
return;
}
if(!set.Open(CRecordset::dynaset,"SELECT * From e",CRecordset::noDirtyFieldCheck))
{
MessageBox("Unable to open database record. (SELECT * e)", "Database Error", MB_ICONEXCLAMATION);
set.Close();
return;
}
/*if (!set.CanAppend())
{
MessageBox("Database does not support adding records. Please\ncontact your server administrator.", "Database Error", MB_ICONEXCLAMATION);
set.Close();
}*/
set.MoveFirst();
while( !set.IsEOF() )
{
set.MoveNext();
}
int lRecCnt = set.GetRecordCount();
int newID=lRecCnt+2;
m_g=lRecCnt;
UpdateData(FALSE);
// Prepare for a new record addition.
try
{
set.MoveLast();
set.AddNew();
set.m_s = "Becky Dugan";
set.m_p = "Becky Dugan";
set.Requery();
set.SetFieldDirty(NULL);
set.Update();
}
catch(CException* pE)
{
char buf[256];
pE->GetErrorMessage(buf, 256, NULL);
AfxMessageBox(buf);
pE->Delete();
}
// Close Recordset
set.Close();
// Close Database
mydb->Close();

Why you have called Requery before actually adding the records,
Try doing this,
try
{
set.MoveLast();
set.AddNew();
set.m_s = "Becky Dugan";
set.m_p = "Becky Dugan";
if (!set.Update())
{
}
set.Requery();
}

how will trace program to conclude the symantic from this program
example :
how i will write code in vc++ to conclude the meaning of this simple program
main()
{
int j[5] ,k ,;
cout<<"welcome";
cin>>k;
k=k+5;
for(i=0;i<6;i++)
{
cout<< h[i];
}
cout << k;
}
thank you

i want write code to compare between tow simple programs writen by c++
compare in syntx and symantic
in symantic compare i want to get the meaning for each program then compare between meaning.
word(meaning)take more than one possibility , here i nead to helping
i have idea : get the symantic(meaning) of program by trace the statments (cout cin exprission for if)and put the goal from statments in variables then compare between variables
if you have any other ideas and how it work , give me
thank you

You might be able to compare two "Hello World style" C++ programs by parsing and comparing with the help of String functions available - http://msdn.microsoft.com/en-us/library/bb759983(VS.85).aspx[^]. So that to some extend you can compare two programs by checking syntax. But still i'm afraid that whether it can be fault proof. It might work, only if you copy-paste the same program. 
Then, comparing logic of two programs  How can we compare the logic by simply analyzing the variables and statements?
OT: Your idea made me think of the "Oracle" character in Matrix Film.

so.... you wish to create AI ????
|
|
|
|
|
exact, i want creat AI
may be exist syntax similarity but do not exist symantic similarity between programs
or reverse may be exist symantic similarity but do not exist syntax similarity between programs
|
|
|
|
|
also i want use rules to compute the similarity
the problem is(how get the semantic similarity between programs or at least how get the meaning of programs)
there are many ideas , but how i can imlement the idea?

note : i want to write code by vc++ to compare between two programs writen by c++
