Re: Can't receive broadcast UDP at the socket

Its fixed now.

For anyone else with the same problem:

In Windows Vista, you cant bind a socket to 0.0.0.0 to receive all broadcasts.

If you are receiving from a multicast address, you need to set the socket options to indicate the multicast group (address) you need to subscribe to, the source address, and the local interface:

imr.imr_multiaddr.s_addr  = inet_addr("224.x.x.x"); // multicast address
imr.imr_sourceaddr.s_addr = inet_addr("s.s.s.s"); // source address
imr.imr_interface.s_addr  = inet_addr("192.168.1.1"); // local receiver interface
retvalset = setsockopt(
  RecvSocket,
  IPPROTO_IP,
  IP_ADD_SOURCE_MEMBERSHIP,
  (char*)&imr,
  sizeof(imr));

what is this 'keyboardmanger() class' supposed to do?

There is sufficient light for those who desire to see, and there is sufficient darkness for those of a contrary disposition.

Ofcourse. Why not! Basically you have to hook the keyboard. Check these articles - Hooking the Keyboard[^] and An All-Purpose Keyboard Hooker.[^].

What is the best way of handling a code like

ComplexLifeForm3-Dec-08 2:02

3-Dec-08 2:02

Hi,

I would like to know if there is a better way of writing a particular pattern of the code as mentioned below. I have been encountering this type quite frequently and do not like the way it is implemented. The code piece is as follows

class Address
{
public:
Address():m_address("")
{}

Address(const CString& addr) : m_address(addr)
{}

CString GetAddress()------------------ (1)
{
return m_address;
}

CString GetAddress() const ------------------ (1a)
{
return m_address;
}

const CString& GetAddress() const -----(2)
{
return m_address;
}
private:
CString m_address;
};

Now somewhere in main method

Address addr("Living somewhere on Earth");

further down a call is made into a third party library which only takes char* and has a method like
void FormatAddress(char* address); -------(3)

Now if I make a call to this method, I must do this
FormatAddress(const_cast<char*>(addr.GetAddress().GetString()); -------------(4)

So my query is whether the whole piece of code is correct, sure it does compile and gives the result as expected
but I am looking to improve my programming skills and want to write a better and cleaner code.

Out of the methods 1 and 1a which is more correct? Does it makes sense to make the m_address variable as mutable.

Thanks and Regards

Generic report writer VC++

Can any one direct me to develop a generic report writer with VC++ 6. What I need is I have some data in some text files and I want to display it in some report-viewer-style. Please don't ask me to dump it into some standard database and use a third-party tool to view it.
There are some utilities provided in this site itself but is not up-to-the mark.

But I didn't get you. What I want is a report-viewer-style presentation. I want to display the data page by page. I want a form-view or a control in SDI/MDI which will represent a white-paper (page) and I can arrange the headers,body,sub-footer and footer in it. Is there any kind of window-class already developed and distributed in codeproject. I just want a child window ( control ) which will represent a A4-size paper. Rest I can do....

You may search for that...

What about simply coding that??? If you just want to show it page by page, a Dialog Application is enough...

Excuse me, a dialog has a status bar? Why can't you just use the doc/view architecture instead? A lot of such work will be done by the framework automatically for you then!
