Welcome to comp.lang.c++! Read this first.

This post is intended to give the new reader an introduction to reading
and posting in this newsgroup. We respectfully request that you read
all the way through this post, as it helps make for a more pleasant
and useful group for everyone.

First of all, please keep in mind that comp.lang.c++ is a group for discussion
of general issues of the C++ programming language, as defined by the ANSI/ISO
language standard. If you have a problem that is specific to a particular system
or compiler, you are much more likely to get complete and accurate answers in a
group that specializes in your platform. A listing of some newsgroups is given
at the end of this post.

The FAQ (Frequently Asked Question) list has a wealth of information for
both the new and veteran C++ programmer. No matter what your experience
level, you are encouraged to read the entire list, if only to familiarize
yourself with what answers are available to minimize redundant replies.
The comp.lang.c++ FAQ is available at http://www.parashift.com/c++-faq-lite/

If the FAQ list does not help, then many regular readers of this group
are happy to assist with problems of standard C++. We have only a few
requests that we ask be adhered to, for the benefit of all:

I would like to add a signal to a Gtk::Entry object, but for some
reason this gives me bunch of errors saying that it is

D:\XWin\include\sigc++-2.0\sigc++\adaptors\adaptor_trait.h|84|error:
no match for call to `(sigc::bound_mem_functor0)
(GdkEventFocus* const&)'

I using Gtkmm 2.10.x for Windows
Thanks in advance!

Can any body help?!
namespace jve{
class Entry: virtual public Gtk::VBox {

Sorry for cross-posting; I'm not sure which group would be more
appropriate, if any.

At present I have 2 applications (installed on the same workstation):
(A) is the main application which is running most, if not all, of
the time. Only one instance of (A) can be running at once.
(B) is an application which send messages to (A). These messages
instruct (A) on what data files to process. This is achieved by
calling (A) with ShellExecute(), passing arguments specifying the
location of a data file (this data file could be any file over the
network of workstations). When (A) receives these arguments, it adds
the data file to it's list of jobs to process.

The above process has been working well. Data can be accessed and
processed anywhere on the network. The downside is the operators can
only "send" data from one workstation.

What I now want to do is install (B) onto all workstations in the
network. Does ShellExecute() work over a network? If not, how to get
around this? What other methods can I use to notify (A) of jobs to
process?

Thanks.

I am enrolled in distance learning class, this amounts to self taught.
I have a book and that is about it. below is my assingment. The book
doesn't prove useful for examples, and I haven't had much look on the
web. I am not asking someone to do it for me, but a nudge in the
correct direction, a website anything!

Write a function to generate an N-node random binary search tree with
distinct keys L through N. What is the running time of the routine?

Assume a linked list of nodes which have an info data member and a
next data member. Suppose a pointer called cursor points to a node in
the middle of the linked list. To move ptr to the next node use:

ptr=next;
next->ptr;
ptr->next;
ptr=ptr->next;
none of the above.

I want to anwser none of the above as i feel it should be cursor-

leading up to last sentacne which is the actual question (To move ptr
to the next node use:). is this a trick question, or am i reading to
much into it?

Why does the following code cause a compiler error?

class A; // forward reference

class B
{
foo()
{
a = new A;

cout << a->bar(); // compiler error here
}

A* a;
}

class A
{
int bar()
{
return 1;
}
}

The compiler error I get is (note the use of 'struct' not 'class'):
