RE: [Dev-C++] what is wrong with the code

[Ioannis V. <iv...@em...>]

I have not studied std::string/std::basic_string thoroughly yet but I
checked TC++PL a bit.

// Constructor
string s=3D'a'; is not valid.


However,=20

string s;

s=3D'a';=20

IS valid.


Also string::assign can be used in the way Haeri told me in a private =
email.


Also s.push_back('a'); can be used.

Yes to both questions 1 and 2. As for 3, it depends on the SQL server, yo=

intend to use.
And you can usually find the documentation (user guide + API guide) at it=

website.

You can find DevPaks and/or example programs to access SQLite, MS Access,
MySQL and Interbase/Firebird at this site:

Hi all -

I have a fairly straightforward requirement: query a database table, then
generate checkboxes and labels to correspond to each row, with the
checkboxes remaining non-static. For example, if my data consists of names
of people, I want to add controls to my form like:

[] John Doe
[] Suzie Q
[] G. W. Bush
[] Jacque Chirac
...

([] represents a check box)

Assuming I know how to query the database and store the data in an array,
how would I use this array to create these controls? Thanks!

RE: [Dev-C++] Dev-C++ with SQL

[Ed C. <em...@ed...>]

That's not entirely accurate, either... MySQL does support subqueries
(sub-selects) with updates as of v. 4.1.0 (out to 82 levels deep). =
Foreign
keys are supported by MySQL in InnoDB tables. UNION is supported as of
4.0.0. The only join not supported in MySQL is the full outer join (left
outer join and right outer join are supported). As for constraints - =
it's
often (usually) better to implement these things in your own code. More =
time
consuming, yes, but often more efficient.

If you want to compare any two databases, go here:
http://www.mysql.com/information/features.html. Yes, that's MySQL's =
version
of the way things are, but it's also pretty darned accurate, and
independently verifiable. For what it's worth, some large brokerage =
firms
and Yahoo! Finance use MySQL as a backend.

It all depends on what you are planning to use it for.  Note that I =

http://www.webtechniques.com/archives/2001/09/jepson/
MySQL's claim to fame is that it provides a reasonable set of features, =
such
as built-in SQL functions, that follow the 80/20 rule: It has the 20 =
percent
of SQL capabilities that are needed for 80 percent of database =
applications.
Developers of simple applications can live without the remaining =
features,
such as stored procedures and subqueries, or can work around them with
creative client-side programming.

PostgreSQL, on the other hand, provides more features than MySQL. These
include more SQL functions, server-side procedural languages, and
sophisticated methods for date manipulation. PostgreSQL also offers
object-relational capabilities and geometric data types. If you're
developing an application that has highly complex business rules, =
PostgreSQL
lets you handle business logic on the database server. ...... Article

COMMENTARY-- I'm often asked, "Do you prefer PostgreSQL or MySQL?" My =
answer
is always the same: "It's a matter of preference." Here is a comparison =
of
MySQL and PostgreSQL databases, offered not for the sake of voicing my
opinion, but to help you make your own decision.

Both systems have much to offer in terms of stability, flexibility, and
performance. MySQL has features that PostgreSQL lacks, and vice versa.
However, my primary focus is to help you determine which of the two
databases to use in your own development.

Before getting into the side-by-side comparison, I need to make it clear =
I'm
referring to default installations. MySQL has many different table types
that support transactions and foreign keys and are compliant with ACID.
However, some of the configurations of these table types are quite =
complex.
Not many Web developers or programmers use the additional table types =
found
in MySQL. With that said, let's compare these two products.

Feature list
Table A is a side-by-side comparison of some of the more frequently used
features of MySQL and PostgreSQL.

Table A is not an exhaustive list of features, data types, or =
performance
issues relating to these two database systems-it just gives a view of =
what
each has to offer. From the table we see that PostgreSQL offers overall
features for traditional database applications, while MySQL focuses on
faster performance for Web-based applications. Open source development =
will
bring more features to subsequent releases of both databases. Table A
					POSTGRESQL 	MYSQL
ANSI SQL compliance 	Closer to ANSI SQL standard 	Follows some of
the ANSI SQL standards
Performance 			Slower 	Faster
Sub-selects 			Yes 	No
Transactions 			Yes 	Yes, however InnoDB table type
must be used
Database replication 	Yes 	Yes

Stored procedures 		Yes 	No
Triggers 				Yes 	No

MySQL and PostgreSQL comparison

When to use MySQL
Why would you use MySQL over PostgreSQL? First, we need to consider the
needs of the applications in terms of database requirements. If I want =
to
create a Web application and performance is an issue, MySQL will be my
choice because it's fast and designed to work well with Web-based =
servers.
However, if I want to create another application that demands =
transactions
and foreign key references, PostgreSQL is the choice.

As an open source developer, I work with both databases on a regular =
basis,
and I typically use all the features of a given database in the design =
and
development process. It wouldn't suffice for me to use PostgreSQL for a
database-driven Web site when my application requires performance.

Even though MySQL is not fully compliant with the ANSI SQL standard, I
should mention that, while PostgreSQL is closer to the ANSI SQL =
standard,
MySQL is closer to the ODBC standard.

Let me suggest some reasons for using MySQL over PostgreSQL:

    * MySQL is relatively faster than PostgreSQL.
    * Database design will be simpler.
    * You can create a basic Web-driven Web site.
    * MySQL's replication has been thoroughly tested.
    * There's no need for cleanups in MySQL (Vacuum).

When to use PostgreSQL
Not many Web developers use PostgreSQL because they feel that the =
additional
features degrade performance. For example, some of the features I use =
are
foreign key references, triggers, and views. They allow me to hide the
complexity of the database from the application, thus avoiding the =
creation
of complicated SQL commands. I know many developers who prefer the rich
functionality of PostgreSQL's SQL commands. One of the most notable
differences between MySQL and PostgreSQL is the fact that you can't do
nested subqueries of subselects in MySQL. PostgreSQL follows many of the =
SQL
ANSI standards, thus allowing the creation of complex SQL commands.

Let me suggest some reasons for using PostgreSQL over MySQL:

    * Complex database design
    * Moving away from Oracle, Sybase, or MSSQL
    * Complex rule sets (i.e., business rules)
    * Use of procedural languages on the server
    * Transactions
    * Use of stored procedures
    * Use of geographical data
    * R-Trees (i.e., used on indexes)

http://brainscraps.com/faq/pg_my.html Are there any good reasons to =
choose
PostgreSQL over MySQL?

(updated for PostgreSQL 7.3 and MySQL 4)

Rick Morris
ri...@br...


To start with, comparing PostgreSQL and MySQL directly is a serious =
mistake.
The real question is "what kinds of applications do you want to build?". =
I
have had experience building complex web-based applications with both =
MySQL
(mainly against my will) and PostgreSQL, and here are some of the
conclusions I reached:

The basic (over)generalization I often hear is: use MySQL for basic =
dynamic
websites, and very lightweight (read: non-critical) applications, but =
use
PostgreSQL for Serious stuff. Well, this is not a bad generalization, =
but
even for lightweight applications, PostgreSQL can really save you some =
time,
and a lot of server-side code, if you bother to learn about views,
constraints, stored procedures, triggers, etc...

Here are just the basics on what MySQL lacks, which PostgreSQL covers
nicely: (I know MySQL is working on some of them, but it is rather late =
in
the game, it seems to me...)..... Article continues

RE: [Dev-C++] Dev-C++ with SQL

[Reid T. <Rei...@at...>]

It all depends on what you are planning to use it for.  Note that I
ended my statement with the word "also", I was just offeringa an
alternative, with alternative options/capabilities.  A quick search on
google will provide hours of reference/opinions to refute/support/decide
for yourself which is better for your purposes( eg the table below
listing features that are not supported my MySql(
Sub-selects 				No
Transactions 				Yes, however InnoDB table type
must be used
Foreign key support 		No
Views 					No
Stored procedures 			No
Triggers 					No
Unions 					No
Full joins 				No
Constraints 				No.)
Are any of these requirements for your development/use??? etc.
So speed and size come with their own expenses.  For most uses I do not
think that the speed differences would be noticeable to the user or
developer.  I am not aware of any postgresql stability issues either.
And I do not know the sizes of either MySQL or PostgreSQL as size has
not been a limiting factor.


http://www.webtechniques.com/archives/2001/09/jepson/
MySQL's claim to fame is that it provides a reasonable set of features,
such as built-in SQL functions, that follow the 80/20 rule: It has the
20 percent of SQL capabilities that are needed for 80 percent of
database applications. Developers of simple applications can live
without the remaining features, such as stored procedures and
subqueries, or can work around them with creative client-side
programming.

PostgreSQL, on the other hand, provides more features than MySQL. These
include more SQL functions, server-side procedural languages, and
sophisticated methods for date manipulation. PostgreSQL also offers
object-relational capabilities and geometric data types. If you're
developing an application that has highly complex business rules,
PostgreSQL lets you handle business logic on the database server. ......

comparison with v7.2 of postgresql, which is now at v7.3.4.

COMMENTARY-- I'm often asked, "Do you prefer PostgreSQL or MySQL?" My
answer is always the same: "It's a matter of preference." Here is a
comparison of MySQL and PostgreSQL databases, offered not for the sake
of voicing my opinion, but to help you make your own decision.

Both systems have much to offer in terms of stability, flexibility, and
performance. MySQL has features that PostgreSQL lacks, and vice versa.
However, my primary focus is to help you determine which of the two
databases to use in your own development.

Before getting into the side-by-side comparison, I need to make it clear
I'm referring to default installations. MySQL has many different table
types that support transactions and foreign keys and are compliant with
ACID. However, some of the configurations of these table types are quite
complex. Not many Web developers or programmers use the additional table
types found in MySQL. With that said, let's compare these two products.

Feature list
Table A is a side-by-side comparison of some of the more frequently used
features of MySQL and PostgreSQL.

Table A is not an exhaustive list of features, data types, or
performance issues relating to these two database systems-it just gives
a view of what each has to offer. From the table we see that PostgreSQL
offers overall features for traditional database applications, while
MySQL focuses on faster performance for Web-based applications. Open
source development will bring more features to subsequent releases of
both databases.
Table A
					POSTGRESQL 	MYSQL
ANSI SQL compliance 	Closer to ANSI SQL standard 	Follows some of
the ANSI SQL standards
Performance 			Slower 	Faster
Sub-selects 			Yes 	No
Transactions 			Yes 	Yes, however InnoDB table type
must be used
Database replication 	Yes 	Yes
Foreign key support 	Yes 	No
Views 				Yes 	No
Stored procedures 		Yes 	No
Triggers 				Yes 	No
Unions 				Yes 	No
Full joins 			Yes 	No
Constraints 			Yes 	No
Windows support 		Yes 	Yes
Vacuum (cleanup) 		Yes 	No
ODBC 				Yes 	Yes
JDBC 				Yes 	Yes
Different table types 	No 	Yes

MySQL and PostgreSQL comparison

When to use MySQL
Why would you use MySQL over PostgreSQL? First, we need to consider the
needs of the applications in terms of database requirements. If I want
to create a Web application and performance is an issue, MySQL will be
my choice because it's fast and designed to work well with Web-based
servers. However, if I want to create another application that demands
transactions and foreign key references, PostgreSQL is the choice.

As an open source developer, I work with both databases on a regular
basis, and I typically use all the features of a given database in the
design and development process. It wouldn't suffice for me to use
PostgreSQL for a database-driven Web site when my application requires
performance.

Even though MySQL is not fully compliant with the ANSI SQL standard, I
should mention that, while PostgreSQL is closer to the ANSI SQL
standard, MySQL is closer to the ODBC standard.

Let me suggest some reasons for using MySQL over PostgreSQL:

    * MySQL is relatively faster than PostgreSQL.
    * Database design will be simpler.
    * You can create a basic Web-driven Web site.
    * MySQL's replication has been thoroughly tested.
    * There's no need for cleanups in MySQL (Vacuum).

When to use PostgreSQL
Not many Web developers use PostgreSQL because they feel that the
additional features degrade performance. For example, some of the
features I use are foreign key references, triggers, and views. They
allow me to hide the complexity of the database from the application,
thus avoiding the creation of complicated SQL commands. I know many
developers who prefer the rich functionality of PostgreSQL's SQL
commands. One of the most notable differences between MySQL and
PostgreSQL is the fact that you can't do nested subqueries of subselects
in MySQL. PostgreSQL follows many of the SQL ANSI standards, thus
allowing the creation of complex SQL commands.

Let me suggest some reasons for using PostgreSQL over MySQL:

    * Complex database design
    * Moving away from Oracle, Sybase, or MSSQL
    * Complex rule sets (i.e., business rules)
    * Use of procedural languages on the server
    * Transactions
    * Use of stored procedures
    * Use of geographical data
    * R-Trees (i.e., used on indexes)

http://brainscraps.com/faq/pg_my.html Are there any good reasons to
choose PostgreSQL over MySQL?

(updated for PostgreSQL 7.3 and MySQL 4)

To start with, comparing PostgreSQL and MySQL directly is a serious
mistake. The real question is "what kinds of applications do you want to
build?". I have had experience building complex web-based applications
with both MySQL (mainly against my will) and PostgreSQL, and here are
some of the conclusions I reached:

The basic (over)generalization I often hear is: use MySQL for basic
dynamic websites, and very lightweight (read: non-critical)
applications, but use PostgreSQL for Serious stuff. Well, this is not a
bad generalization, but even for lightweight applications, PostgreSQL
can really save you some time, and a lot of server-side code, if you
bother to learn about views, constraints, stored procedures, triggers,
etc...

Here are just the basics on what MySQL lacks, which PostgreSQL covers
nicely: (I know MySQL is working on some of them, but it is rather late
in the game, it seems to me...)..... Article continues

[Dev-C++] Problem with getting started with a HTTP Client... [Newbie to Dev-Cpp]

[Chain v. d. K. <cha...@gm...>]

Hi everybody,
I am trying to get started in programming a little HTTP Client to do
batch jobs...
But I have some problems...
First of all I had to look very long for a snippet.
Now I found one, but I am missing some Header Files for this...
They are:
Netdb.h
Arpa/inet.h
Netinet/in.h
Sys/socket.h

Where can I get these?
Or has anybody a snippet of a simple HTTP Client for me?

Greetings,
Richard Homonnai from Austria

That is guaranteed to be undefined behaviour since there is no terminating
'\0' character.

RE: [Dev-C++] bit extraction problem

[Ioannis V. <iv...@em...>]

One "analog" approach that I can think is to convert the
numeric_limits<long>::max() and min() to strings and count the digits. 

Then compare the number of digits of the input with the number of digits of
max or min depending if the input has a minus sign.

If the number if digits is equal  with the equivalent limit, compare if the
first digit is larger/smaller of the corresponding limit (depending on the
minus sign). And so on.

Re: [Dev-C++] 3D graphics library.

NeoEngine. It has TCP sockets as well as UDP.

Haven't had the time to play around with it though.

The fact that there is a Dev-Pak for it is a definite plus.

Re: [Dev-C++] what is wrong with the code

[Hossein H. <ult...@em...>]

Dear Dawood,

> 	can anybody let me know, why the code below is not running.

That's probabely occuring as there is no conversion from char to
std::string. And thus, nor is there an assignment operator. You
are using the assignment operator in the following line:

>    string p = ch;

There is, however, a conversion from char* to std::string, and
you may want to suit from it like this:

string p = &ch;

But I do not recommend it. It would be nicer to explain your 
concrete problem more, so that we can help you more!

Re: [Dev-C++] Compiler

[Per W. <pw...@ia...>]

That was my point - it doesn't matter how portable we wait for a key to be
pressed. When we develop a console application, we normally don't want to
leave that code in the release - if a user run a console application from
the command line, they don't want to have to press a key to get back the
command line.

As long as it's just for testing, any whatever code that waits is fine.
And as long as the command works on the environment the IDE is running on,
that is portable enough.

I think that would be some kind of overkill, because few applications will 
need that feature after development.
I'd rather prefer that devcpp creates a console, then runs the app, then 
runs pause and then frees the console. This even could be done by calling a 
batch file using comspec command line.
