Is there an available method or workaround for manipulating the version information of files external to your own application? I've been having trouble with a couple of vendors updating DLL's but not updating their file versions, which is giving our testing people some real headaches. Any suggestions?

Check out MSDN.

The MFC doesn't have a method that will manipulate versions. Most other file attributes are accessible but the version is not accessible via the built-in functions. Has anyone else tackled this problem?

Hello people,
I try to create a little game on my own with VC++6.0.
In a sample, that I loaded from this website, is the header 'dxerr8.h' needed.
Where can I get it?

Dear all:
I'm writing a com which will be accessed in asp using vc++.I'm not familiar with atl,so mfc is my only choice.I'm a beginner,so I do it step by step.I used appwizard to create a standard mfc dll with automation enabled.I created a new class CMyobj which inherited from CCmdtarget.The automation option I selected for CMyobj is createable by type id.Now I add a method
BSTR GetNameById(LPCTSTR ID)
My first question is if I can call this method directly in ASP like this:
DIM OBJ
DIM ID
DIM Name
obj = server.createobject("Myobj")
Name= obj.GetNameById(ID)
If I can't,what else should I code.(I am a step by step)
I also waht to add a method to return one(or more) recordset(s).How to declare the parameter type for recordset.My declaration is
LPDISPATCH GetNameByDept(long dept)
In the implimentation of this method,I create a recordset,retrieve the data,cast the recordset to (IDISPATCH *).The code is like this:
_Recordsetptr pRs;
pRs->createinstance(__uuidof(recordset))
....
pRs->open(sql,connection_string,...)
return (IDISPATCH *)pRs->Detach()
I create a c++ client and call the method like this:
_Recordsetptr pRs;
long deptid;
pRs = IObjinterface->GetNameByDept(deptid)
It works in c++.But i think it may be a little lucky.It doesn't work in asp.Asp code may be like this:
dim rs
dim obj
dim dept
set rs=server.createobject('adodb.recordset')
set obj=server.createobject('myobj')
rs=obj.GetNameByDept(dept)
rs.open
....
set rs=nothing
set obj=nothing
Can somebody give me some help?example codes,articles,urls or books.

Hi everyone!
Is there anyone that has implement a multicast program on c++, that join a multicast group.
When it had join a group it will logg traffic and saves it in a circular buffer.
But first I will have some help with joining a multicast group.
Please help me,
Stefan

Code to Join:
<br />
struct ip_mreq mreq;<br />
{<br />
struct in_addr imr_multiaddr;
struct in_addr imr_interface;
}<br />
<br />
#define RECV_IP_ADDR "225.6.7.8" // An arbitrary multicast address<br />
<br />
mreq.imr_multiaddr.s_addr = inet_addr(RECV_IP_ADDR);<br />
mreq.imr_interface.s_addr = INADDR_ANY;<br />
err = setsockopt(<br />
sock, <br />
IPPROTO_IP,<br />
IP_ADD_MEMBERSHIP,<br />
(char*)&mreq, <br />
sizeof(mreq));<br />
<br />

I read the following text in the book:
Declaring member functions inside aclass definition
And defining those member functions outside that class definition
Seperates the interface of a class from its implementation.
Clients of a class cannot see the implementation of that class' member
Functions and need not recompile if that implementation changes.
I don't understand the concept of the text and I want to know
Why don't the clients of the class need to recompile if they don't
See the implementation of that class' member functions?
