Hi all,

How to create a C# control (using VC# 2008 .Net) which can be used in any language (mainly in VC++ 2008 .Net)?

Please guide me.

I appreciate any and all comments and suggestions.

Thanks in advance.

Regards,

We discuss native programming here. You may want to ask this question in one of those managed code forums.

How to convert MFC application to OLE?

Hi,

I have a SDI application that is written in MFC. I am just wondering, how to convert this application to be OLE capable application so I can embed it into my C# application?

What I am trying to achieve is to have my main application (written in C#) with my MFC interface inside my main application interface.

Is it possible? If yes, is there any link or tutorial site that I can go to?

Thanks for any help in advance...

Cheers Smile | :)

Why don't you convert it directly to C# code?

Hi Pallini,

The application is too complex. We've bought the code from 3rd party company for 100K. I kind of hoping be able to just convert it to OLE object so can be used within our application.

Any idea?

Hi Cedric,

sorry if there are confusions there, what i mean is i am creating a atl/wtl application not MFC.

Thanks

Are you building MFC application?

If you go to your project properties under Configuration Properties | General, there is a setting whether to use MFC and/or to use ATL.

If your project is not a MFC application, you should set the Use of MFC to Use Standard Windows Libraries

vtable issue

Hello everyone,

When debugging the following code in VS 2008. I think the vtable of object instance z should contain 2 sub-vtables for IFoo and IGoo, the sub-vtable for IFoo should contain func/foo and the sub-vtable for IGoo should contain func/goo), but why actually it only contains 2 sub-vtable, and each of them has only one function item func?

class IBase
{
public:
	virtual void func() = 0;
};

class IFoo : IBase
{
public:
	virtual void foo() { cout << "IFoo : IBase" << endl; }
};

class IGoo : IBase
{
public:
	virtual void goo() { cout << "IGoo : IBase" << endl; }
};

class Zoo : IFoo, IGoo
{
public:
	virtual void func() {cout << "Zoo : IBase" << endl; }
};

int main()
{
	Zoo z;

	return 0;
}

thanks in advance,
George

You didn't specialize those functions in the Zoo class. vtable are used to redirect a function call to the function of the child class which specialize this function. Here, there's no need to redirect the function call because neither of the child classes specialize the function.

I guess this is the reason (it's only a guess) why it doesn't appear in the table. Remember that the table is filled by the child classes when they are being constructed. So, if the child class doesn't specialize the function, there's no need to add it to the vtable.
