The  problem  is  that  the new vUpdate is the version that can't find
devcpp.cfg! I'll guess that it's using SHGetSpecialFolderLocation with
CSIDL_APPDATA but somehow it will not find the file!!!

Maybe the file has changed name?

I  have  copied  the  devcpp.cfg  file  to the directory specified for
CSIDL_APPDATA  and  since I am on a Swedish Windows I have also copied
it to C:\Docume~1\User\Local Settings\Application Data
But ...

So I, and many with me, would appreciate if someone that has access to
the code can have a look and see what's goin on!

I am not sure where my typo is.  Both .txt files exist.

Can anyone please help me.

Marc and Per:

Thanks for the dialog from both of you. As a C++ newbie I learned new
ideas about C++ database setup from your discussion of Rob's problem

For this project, I would like to keep it as close to ANSI C as possible
because I know more about C than C++ and I will be attempting to port it
for use on a Mac as well.

Since I am fairly new at this, I would like to keep it as simple as
possible. Maybe after I get more experience I will improve on what I
already have working. As it is, I already have a challenge ahead of me
determining how to talk directly to my custom hardware via the serial port
in NT. (Mac is easy by comparison - a couple of calls to the Pascal-based
toolbox.)

If I knew how to interface my program with MySQL, I would certainly do it.
Unfortunately, the only way I know how to interface with MySQL is via
Apache for building web sites :)

Mark,

I appreciate your detailed help. It is the attention to details, and the
use of examples, that helps people learn and understand. Unfortunately, I
am smart enough to realize that most everything you said went clear over my
head :(

Thank you very much for the assistance.

Per,

Once again you have given me something to think about with the MySQL. As my
C instructor once said, there are almost as many ways of doing something as
their are programmers and who is to say who has the 'most correct' way of
solving the problem.

Thanks again,

--->Rob

Hello,

With Dev-C++ 4.9.6.0 the config file directory has changed for NT, 2000 and 
XP. You need to update your vUpdate to have it look for the correct directory.
If you cannot autoupdate it, you can download it from :
http://www.zero47.com/devfiles/vUpdate.exe

Greetings,
Colin Laplace

Hi,

there are many solutions. One is put
system("Pause") at the end of your program.

BTW: you get the following program if you create a console program in
dev-c++:

#include <iostream>
#include <stdlib.h>

int main(int argc, char *argv[])
{
  
  system("PAUSE");	
  return 0;
}

Well, Rob's original code snippet was strict C, so any use of templates
and classes might be outside the scope :-)

The problem with giving advice is always what conceptual level to use.

Template-based code with multiple sort orders normally requires a
smart-pointer implementation, which isn't trivial.

So in this case, a truly general application should probably store the
data in a MySQL database instead, but such a solution is clearly out of
scope of the original question...

About the void. Yes, in C++ it's considered unneccesary noise, best to
leave out of the code. The original use of func(void) was actually a
bit of a kludge to allow parametrized function prototypes in C, as opposed
to the original KR style.

Ah yes, because a static data member is essentially a global correct?

Hello,
I have the version 1.614 of vupdate but i get the following error =
message when i open it:
Error: Your devcpp.cfg file is missing
devcpp.cfg is in the root directory of Dev-C++. How can i fix this?
Thanks all, Vargas

Hi Per W,

You're quite right about the GetXXX() methods. Early morning... Coding not
always best. 

Ultimately , I would prefer to use a CString class for name and other string
type properties. Also use TCHAR instead of char, etc. etc. etc. CString
classes generally have a copy constructor so the result of GetName() would
not be able to change the value in the instance.

I did not know that about void. I knew it could be omitted in C++, but is it
convention to omit it?

As for the template container, I did say vector or similar. I guess it
depends on what features you need. Rob was talking about traversing the
"array" using for loops. I think a vector is quite handy for that. The point
was to get away from statically defined arrays.

Subject: RE: [Dev-C++] Question about structs...


What use is a Setname(char *szName) when the GetName() have already sent out
the pointer to the m_szName array? The GetName() method should be declared
const char* GetName() const; The First const to say that the returned
pointer may not be used to change the stored name. The second const to say
that the GetName() method doesn't change anything inside the class CEmployee
when called.

In fact, all GetXX() methods should be written as:
type GetXX() const;

Since this is C++, and not C, all methods not taking a parameter should be
written with empty parentheses. It is only in C, that the void keyword is
needed.

If using template containers, it might also be an idea to use the map
container instead, to allow direct sort and location of entries on customer
id.

If you declare a method as static, you may call it before instancing
an object of the class type, i.e.

class MyClass {
    public:
        ...
        static void StaticMethod();
    protected:
        static int a_value;
};

int MyClass::a_value;

void MyClass::StaticMethod() {
    a_value =3D rand();
}

int main() {
    MyClass::StaticMethod();
    MyClass obj;

A constructor is basically a function that is called whenever an object of
the class is created. It's called in this case:

    MyClass MyObject;

and also in this case:

    pMyObject = new MyClass;

[-open-brace
But not here:

    pMyObject = (MyClass *)malloc(sizeof(MyClass));
]-close-brace

The constructor should have the same name as the class, but no return type
(not void, it should have *no* return type), as in:

    class MyClass
    {
        public:
            MyClass();     // Constructor
            ~MyClass();    // Destructor
    };

Constructors can take arguments, if necessary, like this:

    MyClass(int some_foo);

You would invoke this constructor using

    MyClass MyObject(666);

If you don't specify a constructor for a class, a default set of constructor
and destructor are provided for the class.

You don't have to explicitly call the constructor (in fact, you can't), it
is called whenever the object is created, and the destructor is called when
it goes out of scope. You can see the working if you write a test program
using cout within the constructor, something like this:

    class foo
    {
        public:
            foo()
            {
                cout << "The foo has risen.\n";
            }

            foo(int baz)
            {
                cout << "The foo has risen with " << baz
                     << " coconuts.\n";
            }

            ~foo()
            {
                cout << "The foo had you foolen. Now I will leave.\n";
            }
    }

and then creating objects using different means (static, dynamic).

Actually not radio buttons bot check boxes but :-)

One problem is that earlier versions of the update program doesn't
seemed to work so well through firewalls. My copy always terminated when I
tried to scan for updated packages. After getting a newer update program,
it suddenly started to work ok.

What use is a Setname(char *szName) when the GetName() have already sent
out the pointer to the m_szName array? The GetName() method should be
declared
const char* GetName() const;
The First const to say that the returned pointer may not be used to change
the stored name. The second const to say that the GetName() method doesn't
change anything inside the class CEmployee when called.

In fact, all GetXX() methods should be written as:
type GetXX() const;

Since this is C++, and not C, all methods not taking a parameter should be
written with empty parentheses. It is only in C, that the void keyword is
needed.

If using template containers, it might also be an idea to use the map
container instead, to allow direct sort and location of entries on
customer id.

If it's just for your use, you might try to install cygwin on your
machine. This is a unix emulation layer for windows, and will allow you to
compile and run most unix software directly under windows - inclusive X11
applications.

If your goal on the other hand is to compile an application for general
distribution to windows machines, then you have to do a full port of the
source. Depending on what features the code is using, this might be
interesting times :-)

and when you're declaring the variable,

    database employees[100];
    employee[0].age = 666;

Or, you could use vectors, like Marc said. That would translate to

vector<database> employees;

That would be valid only in C++, not in C. I assume you're working with C.
You could use dynamic memory allocation for variable sized arrays. The
functions that you would use are malloc(), realloc(), free().

Also, you ask about using a variable to index employee_name. I hope you're
not getting confused about NULL-terminated character arrays (strings).

char    name[20];

is a character array. You can use it to store arrays of characters, and if
this array is ended by a NULL-character ('\0'), it becomes a string. So in
the above example, to print the name of the first employee, you would say

    printf("%s\n", employee[0].employee_name);

*NOT*

    printf("%s\n", employee[0].employee_name[0]);

I hope I helped and didn't just confuse you further.

When I create a class object, can I call a member function right away?

I'm thinking that if I have private data I want to initialise when the 
object is created I could put in a member function that does it, but can I 
call it immediately? Instead of

MyClass ObjectOne;
ObjectOne.StartUp();


I know that a constructor initialisation list will do the same, can someone 
show me an example of that as well as I am a little confused by the syntax.

Hello,

I'm working on NT4SP6 and run vUpdate.
After updating a new start of vUpdate leads to an Error that said:

Error: devcpp.cfg not found Please check ...

I checked these folders and I copied devcpp to all that directories I
thought they could take affect.
Devcpp.cfg is in the root directory of Dev-C++ and at serveral
locations in C:\WinNt\profiles...\Application Data.
But the Error is still present even if I restart Dev-C++.

How can this be fixed?

Greetings

Frank
