I would like to add a small text entry on the continuation of the menu bar under MFC. To do this I need to get a handle to the Menu bar.
Is there a way to do this, or is there some other way to add a small text entry after the menu items?
Thanks,
Ilan

I want to make Window application with Boehm GC.
I can build well when I make it in a console application.
The following errors come out when they make it in Window application. 
Please teach a method to make in Window application .
Thank you very much.

Error contents
There is not the function that was able to leave overload to have three arguments by a New operator

class hoe : public gc
{
public:
char p[0x100];
};
void CTest3Dlg::OnButton1()
{
while(1){
hoe *h = new hoe ;
}
}

Well, this is going to blow out your stack in a few seconds, why do you want to do that ?
Try hoe * h = new hoe(); Your error message makes no sense though, your compiler is getting very confused, if this is all of the code.

If Boehm GC works normally, memory leak cannot occur.
>Try hoe * h = new hoe();
An error to compile (+_+;;

Translation seems to have been bad.
Just.
The compile error is "error C2661: 'new' : no overloaded function takes 3 parameters"

I'm curious of how to paint the CTreeCtrl transparently, this means how to create a CTreeCtrl in existed view without cover its content.
just like CATIA's GUI, but I'm frustrated, I have no idea.
Best Regards

The tree control does not draw transparently. If you wish to make it appear otherwise, there are two feasible ways of doing so:
1) draw it yourself, and do it transparently. The control has a rich custom drawing API, and this is actually not too hard. The downside is, there's the possibility you'll forget to draw something correctly in an uncommon situation, or a new (or old) version of the tree will draw itself in a significantly different manner, leaving your custom-draw code producing very odd results.
2) let the tree draw itself onto an in-memory bitmap, then draw this bitmap to the screen while masking out the background color. This can be slower, and you really have to work to handle all the places where the tree tries to draw itself (hint: disable animated expand/collapse), but should be fairly bullet-proof once you're done with all that.

Hi all,
I have a dll and an exe that calls that dll.
I want to find out which are the functions implemented in the dll and which are their parameters in order to use it with a project that I will develop.
Any idea about how to do it? Is there any tool?
Thanks in advance

What you are trying to do is called reverse engineering.
Dependency walker would give you the names of the exported functions from the dll (if any)
You need an assembly level debugger, try playing with OllyDbg.
You would need a good ASM knowledge and a lots of patience.

Hello Guys,
I am too new to WIN32 programming. But knowing my fundamentals right in C,C++ i think the below 2 statements are absolutely fine:-
SOCKET m_socket;<br />
m_socket = socket( AF_INET, SOCK_STREAM, IPPROTO_TCP );</
b>
SOCKET is a typdef of unsigned int
But when i compile this Win32 application it gives me an error on the second line that is the line:-
m_socket = socket( AF_INET, SOCK_STREAM, IPPROTO_TCP );
The error is that "error C2065: 'm_socket' : undeclared identifier"
I am unable to understand why this error, reading some other documents i tried to rectify this ERROR by adding the word SOCKET before M_socket, but then that means multiple declarations of the same variable, and i thought it would give an error but rather it gives a warning..
" warning C4101: 'm_socket' : unreferenced local variable' "
I dont know how to solve this.
Any help regarding this would be highly appreciated.
Thanks in advance,
Zalak Dedhia

Did you included the "Winsock2.h"?

Hey thanks eli15021979,
I had included the Winsock2.h
I got my mistake when i was reading my code carefully.
Thanks and Regards,

Hi Friends,
Please check following examples:
Example 1:
class Base1{
public:
int data0;
};
class Base2:public Base1{
public:
int data0;
};
class Derived: public Base2{
public:
int data0;
};
void main(void){
Derived D;
Base1 *bptr1= &D;
Base2 *bptr2=&D;
}
In above case :
Address of D=0x0012ff74;
Address of bptr1=0x0012ff74
Address of bptr2=0x0012ff74;
Now exmaple 2:
class Base1{
public:
int data0;
};
class Base2{
public:
int data0;
};
class Derived: public Base1,public Base2{
public:
int data0;
};
void main(void){
Derived D;
Base1 *bptr1= &D;
Base2 *bptr2=&D;
}
In above case :
Address of D=0x0012ff74;
Address of bptr1=0x0012ff74
Address of bptr2=0x0012ff78;
My question is why the base2 pointer has different address in above situation?
I have posted this long back but didn't get satisfied answer  ..reposting...

It is easier if you look at how the object is being built.
Base1: 4 bytes (for Base1::data0)
Base2: 4 bytes (for Base2::data0)
Derived: 12 bytes (for Base1::data0, Base2:data0, Derived::data0)
When you look at what is being allocated you see that object D is:
[[Base1::data0][Base2::data0][Derived::data0]]
So the address of:
- D is at offset 0.
- Base1 is at offset 0 because it is the first defined base class for Derived.
- Base2 is at offset 4, it adds to Derived by being tacked on after Base1.

I meant to say that
Why it different for Multiple Inheritance case only?
|

In the first example, since B2 inherits from B1, the address of B2 is the same as the address of B1.
Think of them as circles.
In example one, B1 is a circle. B2 inherits B1 so B2's circle encircles B1. D inherits from B2 so D encircles B2.
In example two, B1 is a circle. B2 is also a circle that doesn't encircle B1. D inherits from both B1 and B2 so D encircles both B1 and B2. However, since B1 and B2 can not exist at the same location in D, one of the two must follow the other. Thus B2 has a different address.

I'm going to patent thought. I have yet to see any prior art.

Here as u say B1 & B2 does not exist on same location, same case is for normal inheritance too..why it needs special handling in MI only?

This will require replacing MSGINA.DLL with one of your own.

Hey, I was wondering if there was a way to prevent operator new() from calling the class constructor.
I have a CDialog derived class that creates a modeless dialog when it's constructor is called and I want to limit it to one instance. So what I want to do is when the dialog's operator new() is called, I want it to return a pointer to the already existing dialog. To accomplish this I have overridden the operator new() function
CWnd *CMyDialog::pMyDialog = NULL;
#ifdef _DEBUG
void CMyDialog::operator new(size_t Size, LPCSTR File, int Line)
{
if (pMyDialog)
return pMyDialog;
else
return CDialog::operator new(Size, File, Line)
}
#else
The problem is that once operator new() returns it immediately jumps to the class constructor, which initializes everthing to NULL, totally messing up the dialog that was created previously.
Now I know that I can keep a pointer for the dialog in it's parent window, and check that pointer to see if the dialog is active, but I want to try something different if it at all possible. This way the dialog can be created or accessed from any other class without having to have access to the stored pointer.

Because I did not know what that was until now
Thanks for the suggestion, seems to fit the bill perfectly.
Do you have a prefered method on how to do this? or are the articles present here on CP all equal in their implementation?
