There is no 'real' procedure. What you have to do is start a new project and copy paste the code you want to reuse. Of course, this depends a lot of your project.

when I convert my project from VC6 to VC.NET2005,I met a compile error named Error 1 error C2668: 'fabs' : ambiguous call to overloaded function the corresponding code as follow
if ( fabs(_C[0] < SVarSet::PT_COINCIDE)&& fabs(_C[0])<0.0001*fabs(_C[4]))
where _C is a function parameter whose type is real64 *_C
I find the reason in MSDN but I can't correct it,who can tell me the answer,many thanks

Maybe instead of
fabs(_C[0] < SVarSet::PT_COINCIDE)
you should have
fabs(_C[0]) < SVarSet::PT_COINCIDE
Otherwise the compiler cannot choose between fabs(float) and fabs(double) having a parameter of boolean type.

Hi,
Please let me know if this is ok to shutdown(or break) the loop...
//this is in server side, server listening for new connections
while(1)
{
start:
clnt_sokt = accept(m_sokt,..)
if(clnt_sckt == INVALID_SOCKET)
{
if(WSAGetLastError() == WSAEINTR)
break;
else
goto start;
}
}
void StopServer()
{
closesocket(m_sokt)
}
Call StopServer() would close the server listening to socket
Thanks
Rove

If you do the same, the established connection with client will reset.
I read somewhere that using goto: is not a good practice.
There are alot of sample code regarding creating simple server with multiple clients. Google for it

Below i'm trying to give my code structure, so that it can understandable
I've a class named "Chi",
i've taken a ptrvariable to that class(hi), say tp;
tr, is simple class variable( of "hi")
now i've a structure called "hi"...
i've a list to store the all structure variable....
now i want to store the tr(variable of Chi) in that list, nd then it gives me the error...[Can't convert struct hi to Chi*]
my code in brief::
class Chi:public someclass
{......
......}// this is the cpp file
in .h file i declare a variable of class Chi,
and i have struct hi

 This is not clear at all: it is really confusing what you are trying to explain: Chi, hi, tp, tr, "hi", ... 
Put some code (with a short description if required) and a precise question.

You have to understand the sense behind converting data.
For instance:
class A : public B
{
}
class C //or struct
{
}
You can:
A *p = new A;
B *p1 = (B*) p; //because A inherits B !!!
you cant
B *p2 = (B*) new C;///Bullshit C isnt a B (or A)
because C is NOT a B.
You can store any data type in a void*, but you have to cast it with a legal cast to a object.
I guess you a learning working with pointers?

Check this.[^]. This is using windows sock function for file transfer.
writing a simple client or server is easy. you will get loads of code if you google for it.
Some sample source files

Shall I point out one thing? Don't send a message on excitment. Sometimes it may feel bad to others. Here people are not answering as part of any contest. It would be nice if you specifically say what do you are bugging with or seeking for rather than what your feeling and urgency. Hope you will take it in its sense

Hi all,
i need to execute code on the primary form
(the one the project start with, CalphaDlg in my case) from another
modal form.
I try with
CalphaDlg::OnBnClickedButton2();
including "alphsDlg.h" of course,
but i get the error
error C2352: "CalphaDlg::OnBnClickedButton2": not valid call to non static member function
What should i do ?
TIA,
Desmo16.
|
|
|
|
|
In the second dialog create a pointer to the CalphaDlg as member variable
CalphaDlg *m_pCalphaDlg;
now from the first dialog set this member variable
Now if u want to cal any function of the main dialog, use this pointer and call.
m_pCalphaDlg->OnBnClickedButton2();
nave

Sorry i made the first and the 3rd step but i don't understand the meaning of
"now from the first dialog set this member variable"
What should i do exactly ?
|
|
|
|
|
i hope u will be calling the DoMAodal of the second dialog from the first dialog. if so do like this
let m_SecDlg be the second Dialog then
m_SecDlg.m_pCalphaDlg = this; // this is what i mean
m_SecDlg.DoModal()

Yes I understood that later.
Now it's ok.
Thanx.

Hi all ,
I created a dialog based application in MFC and added one menu item (ID_MENUTEST_MENU1 )
after hitting on that menu only ON_UPDATE_COMMAND_UI andON_COMMAND gets called .
i want to know the use of ON_COMMAND_EX and when it gets called?
CODE:
ON_COMMAND(ID_MENUTEST_MENU1 ,OnCommand1)
ON_COMMAND_EX(ID_MENUTEST_MENU1 ,OnCommandEx1)
ON_UPDATE_COMMAND_UI(ID_MENUTEST_MENU1 ,OnCommandUI1)
void CDataExchangeDlg::OnCommand1()
{
AfxMessageBox("Oncommand1");
}
BOOL CDataExchangeDlg::OnCommandEx1(UINT nID)
{
AfxMessageBox("OnCommandEx1");
return true;
}
void CDataExchangeDlg::OnCommandUI1(CCmdUI* pCmdUI)
{
AfxMessageBox("OnCommandUI1");
}

In think in case of handlers defined with ON_COMMAND_EX macro, the MFC message dispatcher is able to process your commands in chain manner.
For instance, if you have two handlers for some command -- one in a view class and another in main application frame -- and use ON_COMMAND macro, then after processing the message by the view, no other handler will be called.
But if you use ON_COMMAND_EX macro, and the view’s handler returns FALSE, then MFC will continue routing and will call the main frame’s handler too.
In your sample, the OnCommandEx1 handler will be never called because of previous OnCommand1, even if both of them were declared with ON_COMMAND_EX. This macro has effect only in case of different command target objects.
That’s my opinion.

Thanks Viorel.
I removed ON_COMMAND then ON_COMMAND_EX taking effect .And as it is tanking nID so it is useful
and proves that it is just an extension to ON_COMMAND .

Suppose send buffer has 2 bytes free
n=send(s,buf,16,0)
Will 2 bytes of buf be sent?
I call send in FD_READ according to the received data. If I can't send the data entirely, how can I send it after that.
