I have an abstract class A which contains pure virtual functions.class B derives from it publicly and B has its own functions which are not virtual.Class C derives from B and calls functions of B .C also implements functions of A.now when I am trying to instantiate C i.e creating object of C its giving error that "cannot declare variable cobj of abstract type A due to pure virtual functions".It is happening only for Linux,in Windows its working fine.Can anybody help pls?

Did you implemented all of the virtual methods?
Could you post the code?

Its like
Ibase.hpp
----------
class Ibase
{
public:
virtual bool get() = 0;
};
Abase.hpp
---------
class Abase :public Ibase
{
public:
bool getnumber();
}
baselinux.hpp
-------------
class baseLinux : public Abase
{
public:
virtual bool get();
}
driver.cpp
-----------
baseLinux bL; //here showing error that i have mentioned
error is coming only for linux.
|
|
|
|

I got the solution.I had given parameters in get() of baseLinux whereas it
doesn't take any parameter in Ibase.
|
|
|
|
|
This is working fine in linux as well
But, Did you define the function "baseLinux::bool get()" anywhere?
as below:
class baseLinux : public Abase
{
public:
virtual bool get(){}
}

Hi
Is there any way to understand a running application is calling a function, method or sub? In other words I want to communicate with other running proccesses.
For example I want to know when Notepad.exe is calling the Open function.
Thanks.

So are you wanting to know how to put the SQL statement together?

i have written this line of code in my stdafx.h file
#import ".\Debug\QuoteQuad.tlb" raw_interfaces_only
now what i wanted to know is how could i get its uuid
(__uuidof(My_managed_class_uuid_goes_here))
can anybody help me in this
thanks in advance

Add the named_guids attribute to your #import statement.

Well, other than the things you've already written there's not much to "get".
What doesn't work?
Does it compile and if it doesn't; what error messages do you get?
What does your #import statement look like exactly?
What does your statement that uses __uuidof() look like exactly?
Tip: the imported typelib will get a namespace of its own so you have to prefix the CLSID with the namespace unless you've written something like using namespace MyTypeLib;.

......

I'm making a qualified guess regarding the name of the GUID for the server, but based on the above I think that the call should look like this:
HRESULT hr;
QuoteQuad::_Demo* pDemo;
hr = CoCreateInstance( __uuidof( QuoteQuad::CLSID_QuoteQuad ),
NULL,
CLSCTX_INPROC_SERVER,
__uuidof( QuoteQuad::_Demo ),
(void**) &pDemo );
I don't understand why you're using IShellLink when you say that the interface you're trying to use is _Demo.

As I said: I'm making a qualified guess about the name of the CLSID for the server you're trying to create. Apparently I guessed wrong.
In your target directory you have a *.tlh file that is generated by the preprocessor from the typelib you imported that should be named QuoteQuad.tlh.
Open it! You'll find the correct names for the GUIDs there.
Even the IntelliSense should provide you with the members of the namespace after you've typed the name of the namespace followed by the scope operator, e.g QuoteQuad::
