AFAIK, the compiler creates a separate vtable for each class; adds a pointer to this vtable, called the virtual table pointer or vpointer, (often the first member) and generates hidden code in the constructor for each class to initialize its vpointer to the address of the corresponding vtable. There is one vtable for a class that contains a virtual function and a vtable associated to each of the class that are derived from the base class containing that virtual function.
Somethings seem HARD to do, until we know how to do them.

Can you post some code? What about a call stack? We'll need more information...

Hello sir!! the code works when i increase the size of the stack, but is there any better way of making the code work?? yes, the function uses the dialog memory.Thanks...

This obviously cannot be answered without seeing the code in question. Do you have any recursive calls? Do you have any very large stack-based variables?

u might have selected win32 console application as project type. Try taking a win32 project.

Yes I did select win32 console app proj, and i want a console app project but without the cmd window can it be done?
I need it for a kind of autorun for running other app without poping itself up on the screen.

I dont understand why u selected the console app proj.. any way try the following code
ShowWindow( GetConsoleWindow(), SW_HIDE );
nave
|
|
|
|
|
Because when I try win32 proj the proj window pops up - is ther's a way to hide this window?
Moreno

did ShowWindow( GetConsoleWindow(), SW_HIDE ); work for ur console application?

I haven't seen a window like that.( i doubt u have take "hello word application" )
Take a "Win32 Application" then in the next option select "Simple application"( I am using VC6 now. so i dont know if this is same in vc2005 )

The code didn't work I get an error.
but anyway even if it did this will be after the window pops up
In vs2005 after I choose win32 proj ther is no "Simple application".

After I choose Win32 new projectI get the options:
Application type:
Windows application - I get a win window popup
Console application - I get a cmd window popup
DLL
Static library
Additional options:
Empty project
Export symbols
Precompiled header
Add common header files for:
ATL
MFC
ShowWindow( GetConsoleWindow(), SW_HIDE ):
now i don't get an error but it just doesn't work:
in Console application - The cmd window popsup
in Windows application - The win window popsup
maybe ther is an option in the proj properties to hide the cmd window?

create a fresh Windows application. delete every thing inside the winmain() function. then tell me the result.

when i tested, it worked.

Ok It worked but it's not in winmain but in:
BOOL InitInstance(HINSTANCE hInstance, int nCmdShow)
{
HWND hWnd;
hInst = hInstance; // Store instance handle in our global variable
hWnd = CreateWindow(szWindowClass, szTitle, WS_OVERLAPPEDWINDOW,
CW_USEDEFAULT, 0, CW_USEDEFAULT, 0, NULL, NULL, hInstance, NULL);
if (!hWnd)
{
return FALSE;
}
//ShowWindow(hWnd, nCmdShow);
UpdateWindow(hWnd);
return TRUE;
}
Thank you all

I have three classes all derived from the same base class. Is it at all possible for one class to call a function in another class? I'm guessing the base class would need to store a pointer to the derived classes, which in my opinion is a little messy. If there is an easier way to do this, please tell. Thanks.
