Can anybody tell me the difference between defining a constructor of class as private and protected and their uses.
|
|

The same difference there is between defining any class member private and protected  .

To complete what CPalllini said: if you have a private constructor, you won't be able to derive a class from this class (the child class cannot access the constructor of the base class, so you'll have a compilation error). In both case, only the class itself (or derivate) can create an instance. The only way to do this is through a static function (because to be able to call a non-static function, you already need to have an instance).

Adding to other replies, private, protected access specifier acts the same way as with other functions; with private the member is not accessible outside the class, you can make this property useful in many ways;

You know that if you provide any constructor (even one which is not the default), then the default constructor which is implicitely added by your compiler will be ignored ?
Try your code and remove the default constructor. Try now to construct an object by using its default constructor. You'll see that you won't be able to compile because there's no default constructor for the class.

Yes, You are correct, I should have compiled to remember it.

Hi All !
How do I create a tooltip (using CToolTipCtrl) for a CStatic member in a dialog ? for a CButton class member it works just fine but for the CStatic class member I get no tooltip.
Thanks,
Amit

Does your static control have the SS_NOTIFY style?

Hamid Hi !
Thanks for the link - it helped,
However, when I try to create it dynamically (using Create function) I get an error...

How can i copy a string (LPSTR) to a wide string variable (LPWSTR).
When i am assigning directly (=) i am loosing some data.
Thank you.

You sure about that? Such an attempt will cause a compiler error.
LPCSTR pChar = "LPCSTR";
LPCWSTR pWChar = L"LPCWSTR";
pWChar = pChar;
Even if that made sense, which it doesn't, it would only copy the pointers.
Don't tell me you cast the problem away!
Show us some code.

sorry. I casted the problem away
LPCWSTR pWChar = (LPWSTR) pChar

Don't! The compiler issues an error for a reason! Calling a dog a cat doesn't make it one!

Actually the compiler is happy about it (I suspect it enjoys such mistakes...).

They are quite different beasts, do you need to convert.

I suggest you try to understand the concepts that are behind by reading this series of articles[^]. At least, you will understand why you can't cast the pointers directly.

Hi,
U cannot directly cast a LPSTR to Widechar LPWSTR and if u do that u will lose data. use API MultiByteToWideChar to do it.
thanks

Actually you don't loose any data. Anyway your conclusion is correct: there must be a conversion to get a corrensponding string as result.

I am to create a DLL utility which will read properties file i.e. similar like the log4j.properties.
Kindly please let me know how should I go about it.
Thanks.
