I've tried doing the deletes and destroys, but it just doesn't work. I have the pointers defind under the OnMouseBtnClick and when I go to delete VC says that it is undefined.
I'm trying to find the cleanest and most modular way to do this, am I going to have to define these pointer ahead of the menu call making them global to the rest of the code?

Hi,
I am working on FTP project and it is already pretty large and complicated. It is written in MFC. And now, I have to add support for installing/uninstalling/running/pausing/stopping NT service. (myproject->NT service). I read some articles about it in MSDN, but I still dont know how to use it. I dont know, in which of my existing functions should I call these "services API function", such as StartService, ServiceMain function, Handler and so on...Can you help me ? Thanks Standa.

Hi, I am working on FTP server and I need to manage IP Access. How can I get IP address from client socket which I accepted ??
And second question: dont you have/know any reliable and tested mechanism for providing IP Access restriction (eg. IP 200.100.50.25 cant access our server between 21.8.2002 23:00 and 22.8.2002 12:30) ??? I chiefly mean the format for saving these rules and for reading them (from textfile or whatever)...
Any help will be appreciated !!! Thanks, Standa.

With Berkeley sockets you need to pass a sockaddr_in struct to your accept() call like so:
<br />
struct sockaddr_in their_addr; <br />
<br />
<br />
<br />
sin_size = sizeof(struct sockaddr_in);<br />
new_fd = accept(sockfd, &their_addr, &sin_size);<br />
Upon connection you can read the values from the their_addr struct and get what you need.
As for your other question I personally can't answer it in the context of a forum post. I would just look at how other programs handle rules like that for guidance. It's the kind of thing you can make as complex as you want, but I would really strive for simplicity to reduce logic errors.

I have an ATL(3.0) project that contains a composite control. I need to trap all the events that occur when the control has focus. I though I had accomplished this and then discovered the keyboard events( WM_KEYDOWN, etc) are missing. I investigated the problem and was advised to override the pretranslateaccelerator routine from the base class. I did so but found it never gets called with the keyboard events. Any help or examples would be appreciated. If you need to re-create the problem, create an ATL project with a composite control and then try to capture pressing and key on the keyboard. thanks in advance

i often see people in the forum write c#, what does it mean?
is it just c or c++?
if not, what is that? what is its main usage and advantage?
thx

it is a new language from MS. it's similar to C++ and Java, but is somewhat more high-level.
it's main advantage is that it works well with the new .Net stuff.

do u know the name of its compiler and how to get it?
(i.e. Visual C++ if one of compiler of C++)
does c# close to c, c++ or java?

You need Visual Studio .NET, which has a C# compiler and stuff.

why would a CListCtrl move an item without my permission? i don't have any sorting set. it's an Icon view, Auto-arrange list view and it hates me.
i do this:
lvi.iItem = 0;
int idx = GetListCtrl().InsertItem (&lvi);
TRACE("idx = %d\n", idx);
idx is, correctly, 0.
but where does the item end up? position #3.

Well, i can´t think of something that you could have missed, and if the returned index is ok, i have definitely to agree with you : it hates you

Doesn't the icons in icon view always end up at the next free space?
Internaly it have index 0, it just looks like it is 3..??

yeah, that's what it seems like.
looks like i'll have to take out all the items, and insert them back, in the order i want. what a nice feature...

I've been assigned to recode a large part of my company's application. Mainly to reduce the large amount of bloat and code in our dialog class. One of the main portions that I want to reduce is the code surrounding our CTreeCtrl class. I was planning on just creating a new class and directing all of the CTreeCtrl events to this class.
Here is where my problem comes in. I've tried creating the class from the class Wizard in VS however it wants me to create a class that inherits from an MFC class. What is the appropriate class to inherit from here?

Awesome. That's what I was hoping for. Because of the class wizard that popped up in the particular place I was crating a new class I wasn't sure if it had to be MFC for the Message Maps to work properly.

This is a strategy question to try to get me pointed in the right direction.
My application records several items of data held in a structure into a log file. It also is able to read those log files and process them. As the application evolves, the contents of the structure increases and decreases ... elements are added and removed, based on evolving need.
While the software and the log files matches for a particular version, I need to be able to have sw version 3 read data log version 2, and data log version 1. Backward compatibility. It seems to me that I need multipe structures and multiple classes to read and write the log files, each class meant to handle the log of a particular version. The structure should be contained in the class with accessor functions to provide the data elements.
If the document object handles the File/Open, and it gets the filename from the dialog, and then opens the file and reads the first 4 bytes (an int) to determine which data log version is required, the doc would then instantiate an object of that log version class to handle reading the log file records into the structure. But, this seems to separate the file opening from the file reading, and it seems like that ought to be contained fully in a class meant to handle the data log files. If I don't open the file first, how else could I know which version class is needed?
Does this approach make sense? Is there a better way to keep software versions and data log versions compatible? What do others do to handle data files of different structures based on evolving formats?

That´s exactly what i do for my app. In fact, I have only _one_ type of structure, containing _all_ the stuff, and i only fill what is necessary given the version number. BUT i can do that only because i know there won´t be any further version (so the struct size won´t be larger) ... i guess that´s not the good solution anyway

When faced with that problem, I typically use a file format that's similar to or based on the INI format. For instance...
[SoftareInfo]
Version=3
[Data]
SomeVariable = read me!
Bob = green
...
That way the code can just pluck out the variables it needs. If it doesn't find one it needs, it can use a default value.
This is also nice because it can be *forward* compatible too!
The one thing I *wouldn't* do is rely too heavily on MFC serialization. It can work in many cases, but if your file format has a major change, then your task becomes extremely difficult.
Of course, if you have *existing* file formats, then perhaps your classes that read data need to keep track of the version... like:
SomeClass::ReadData()
{
if(version >= 3)
read some piece of data
else
older versions stored that piece of data differently
...
}
Even if you win the rat race, you're still a rat.
