If you declare the default constructors A::A() and B::B() then you must provide an implementation as well (the same applies to the destructors A::~A() B::~B()).
Hence you either write:
class A
{
};
class B : public A
{
};
or
class A
{
public:
A(){}
~A(){}
};
class B : public A
{
public:
B(){}
~B(){}
};

if it is a resource dialog, just set the type to bitmap and select the image in the properties window.
If it is a coded control you need to pass in the BS_BITMAP flag with the flags to CreateWindow and then send the button a message with BM_SETIMAGE and a loaded HBITMAP or HICON with preferably PostMessage otherwise SendMessage

You got answers last time you asked this question[^]. Did it not work? What problems did you encounter?

Hi, whenever i run any code of C++ in Eclipse, it says binary not found??
|
|
|
|
|
(never used eclipse, but I assume its working is somewhat standard )
1- do you compile and link the code with no error ?
2- is there some kind of setting telling where the IDE (eclipse) can find the application when you want to "run" it ?
3- can you look in the folder where the source code is if there are obj files and resulting application ?
Other than that, I've got no clue.
Watched code never compiles.

What binary? Do you have the C++ CDT[^] installed?

yes, n it is eclipse itself i guess
|
|
|
|
|
err.... not properly.
Eclipse itself is an empty interface with some API.
The CDT (C developmenet toolkit) is a (set of) plug-in that should be installed on top of it.
But there are also eclipse-cdt bundles (hence you're possible terminology confusion)

Hello,
is there any other function to rename folder as _wrename(old_name, new_name);
Thanks for any help
Arrin!

ShFileOperation (or IFileOperation ) is your friend.
look at the documentation on MSDN.
Watched code never compiles.

Hi,
thanx for answer!

Hi,
i forgot to say that this is a directory in a LAN?
In this case, do i have to do the same, to use same function SHFileOperation for network operations???
When i tray to do this, i receive an error like this "Invalid File path"??
Thanks
Arrin

Beware to string escapes: LAN names like \\server\share\dir\file.ext should be "\\\\server\\share\\dir\\file.ext".
It is one of the most common errors.

An alternative to SHFileOperation is using MoveFile[^] or MoveFileEx[^] APIs. These functions can rename either a file or a directory.

Try
MoveFile(LPCTSTR currentNameOfFolder,LPCTSTR newNameOfFolder);
Example:
MoveFile(_T("D:\\TestFolder\\RenameMe"),_T("D:\\TestFolder\\MyNewName"));

The "\" is known as the (or one of?) "escape" character.
that means that if you want to put a tab, for example in a string you would put "\t" to indicate a tablature; that means that the string will look at the "\" and the next character after that and see a "t" and will understand it as a "tablature" (same thing for quotes and double quotes)
so, in general, when a string (CString) encounters a "\" in a string it will check the next character and see if it means something.
the question is how can I put a literal "\" in string without being recognize as an escape character ?
the anwser is to double the "\" ...
str = "C:\\Windows";
When hard-coding paths in string one should always put "\\", but, for example, if you have a UI with an edit box to type in the path, you don't need to use the "\\" you can just use the "\".
Watched code never compiles.

Of course '\' is the only C/C++ escape character for literal strings.

You should also print out the contents of wfd.cFileName to see exactly which file or directory you are displaying attributes for.
I must get a clever new signature for 2011.
