hum, so i didn't understand your question...
in MS-DOS, C:\> is the common prompt to tell that you are located on the root directory of the C: drive.
the ver command displays the actual version on MS-DOS installed (or windows since WinNT4 - as it doesn't need dos anymore)
if i still don't answer your question, please rephrase

Here's how I'd go about doing it:
ostringstream ss;
ss << "PI = " << 3.14159265;
string s = ss.str();
Includes you'll need:
<string>
<sstream>
Assumes:
using namespace std;

std::basic_string is a template.
You can't convert to it, but only to its instantiations e.g. std::string or std::wstring
That said, I would take a look at boost.orgs lexical cast[^] or format[^].
Free but peer-reviewed code. Some of it will be part of the next version of the C++-Standard.

Hi, i have a property sheet which is tabbed and the tabs are stacked
there are 6 tabs which strech across two lines,
however when the property sheet is first called, the lower line of tabs seem to be
hidden, they only appear when i have clicked onto another tab
i have posted an image of what i mean, as its hard to explain [^]
Can any one help
thanks

How are you adding the pages to the sheet?

m_sheet.AddPage(&m_page0);
m_sheet.AddPage(&m_page1);
m_sheet.AddPage(&m_page2);

Can we say that class/objects in C++ implicitly supports state based programmming?
|
|
|
|
|
What do you mean exactly ? Can you be more specific ?
You still can have a kind of 'state machine' in a class if you want to. I don't really understand what you are asking for.
|
|
|
|
|
well let me explain,
Say I have a class
Class SunLight{
public:
bool state;
void set_state(bool state_value)
{
state=state_value;
}
};
Here I am have function which changes the data member value of my class. So in general I am changing the state of my class.
in C language I can do same using procedure programming but where I need to explicly declare and hold/preserve variables and manuipulate by passing those variables to function.I think this extra burden on programmer.
finally Such kind of implementation can ne implemented as shown above in C++ using classes. So can we say that for state based system my class are useful and efficient, hence the argument "C++ classes implicilty supports state based programming".

My sole intension was to validate the thing I put here...If there is any conceptual missunderstanding , u may please state here.
|

You can see things as 'encapsulation' also: it is a little bit the same concept. Each object retains its state (that is not directly accessible for the external world) and you can modify it by the use og public functions.
I think it's the same as what you said.

|
|

i still don't understand the whole thing you expllain/ask for (if ever), but if you use a bool, then your object will have only 2 states : ON/OFF, enabled/disabled, true/false...
so, i'd suggest you (once you"ll need to emulate a much bigger state machine), to use an enum which defines one flag per state...
