Hey Folks,
I hope you'll be nice to me and let this post go through even know its
mysql and not directly php.
But of course my script is php.
The problem is, that my Table (1,8 MIO entries/100 MB/MyISAM) is not
working anymore. Everytime my script wants to write in something the
number of entries decreases, and at the "Overhead" column the number is
growing.

When define member like "string" type for a class, we can either define it
as "char *" or "string." I don't know which one should be better. My
concern is that "string" has some "overhead" though its usage is so
convenient. Additionally 'string' member could be needed to pass into a
function which expect a variable of 'char *' Then the function call could
make the code looks like,
function(TheObject.PassMeTheStringMember().c_str(),...

I want to sort a vector with the std::sort function. There are two
functions: one with two arguments, the other with three arguments. I
am using the one with three arguments. I noticed that there is a huge
overhead of using this function, which comes from copying the function
object, i.e., the object that compares the elements of the vector,
which is passed to the function not by reference but by value.
Now, at the end of this mail...

Hello there,
I would like to know what overheads there are to think of when using RTTI. I
understand that enabling RTTI increases the sizes of the classes, but not
the objects themselves. This doesn't sound too bad.
What I'm worried about is whether there is a general performance overhead
caused by enabling RTTI, such as enabling exceptions makes a C++ program
slower even when there are no exceptions actually used.
Are there similar...

Hello,
this is something I've been asking myself for sometime ... and now I'd like
to clarify this point.
When should the try block start in a method??? What I mean is, does having
all the code instead of a smaller set of it inside a try clause add any
overhead??? 1What I'd like to understand is if, to be completely sure that
no unhandles exception will get to the user, I can place all the code inside
a try block
and if this practice...

By turning Option Strict on, is there extra overhead? For example w/o it on
the following doesnt get flagged:
validxhtml.Attributes.Add("height", 22) but with it on the 22 is underlined
and the message is "Option Strict On disallows implicit conversions from
'Integer' to 'String'.". I then use validxhtml.Attributes.Add("height",
cstr(22)) and the blue squiggel goes away with strict on. By using cstr is
there extra overhead created?

Hi, I am in the process of developing a small application that sits in
the task bar and at a set interval polls an IIS web server for
information. The process involves the client sending anything between 3
and 30 characters of data and the server returning anything up to 50
characters of data.
I need to identify the overhead on the network so I can determine the
network utilisation of the application. The sort of questions I need to

Hi,
I would like to follow Stroustrup's advice of separating an object
interface (abstract class) from an object implementation (concrete
class), See Section 15.2.5 in Stroustrup 3rd Edition.
Specifically, I want to create an abstract base class that defines an
object interface:

So far the only way that I found to do this was by making a
single global instance of the container class and providing
access to the contained class, through this single global
instance. Are there any other no-overhead ways that a
contained class can access its container?
The obvious choice of passing (a pointer or a reference to
the container) to the contained class is not a no-overhead
solution, it requires both memory and time. I am...

Hey guys,
I've a mysql database with about 112 tables and views. All of the tables are INNODB. I manage this with phpmyadmin, and stuff have been pretty much fine over the last one and a half years.
Suddenly I noticed this problem:
I needed to transfer the installation to another network server (running WinXP); I used the export feature in phpmyadmin to get out the table structure, and recreate them in the new database. This all happend...

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
