You can set this member variable of CFrameWnd class to FALSE...
CFrameWnd::m_bAutoMenuEnable = FALSE;
Do this inside the mainframe constructor. When this member variable is set to true new menu items with no ON_COMMAND and ON_UPDATE_COMMAND_UI handlers are disabled. By setting this member to FALSE you can prevent this.

SAME IS THE CASE WITH THE TOOLBAR HOW TO SOLVE THAT

Override OnCmdMsg and return TRUE. Don't forget to call the base class handler.
For eg:
BOOL CMainFrame::OnCmdMsg(UINT nID, <font color=blue>int</font> nCode, <font color=blue>void</font>* pExtra, AFX_CMDHANDLERINFO* pHandlerInfo)
{
CFrameWnd::OnCmdMsg(nID, nCode, pExtra, pHandlerInfo);
<font color=blue>return</font> TRUE;
}

Hi,
I want to know the difference between unions and structures in c++ world.

Hello Nibu,
Good.
Good style.
I like it.

structures reserve memory for all the variables inside it. but Union takes up memory for only the thing that we assign value. and overwrites the same if a value is entered to antoher variable inside it.

takes up memory for variable who has maximum amount of byte.

Your link contains content that verifies what the person-you-are-responding-to said...
The compiler allocates a piece of storage that is large enough to hold the largest variable type in the union What is the confusion? 
Peace!

hi VuNic,
VuNic wrote: Union takes up memory for only the thing that we assign value
i'm sorry to say that you are wrong.
a union occupies as much memory as the wider field of the union.
lets say we have this union :
union myU {
long l;
char c;
};
then, even if you assign c which is a char, so 1 byte, the union will weight 4 bits because the longuest field is l (long is 4 bytes).
myU u;
u.c = 5;
ASSERT(sizeof(u) == 4);

i'm sorry, but the author of that article is really not aware on what unions are !!! 
all the fields of a union starts at the same address, so, they overlap, and the cosequence of this is that the union length (whatever data it's benn assigned) is the length of the larger field...

The SDK(telephony) which i'm using is based on 100's of Unions. in that its said that Not all of the items inside the union would be used at a time. moreover only one would be used at a time. so it saves memory when you use Unions. hmm.. i'll check it out again.

The compiler has to allocate enough space for the largest item in the union. If you create a union that contains a char (1 byte), a 32-bit int (4 bytes), and a double (8 bytes), the size of the union will be 8 bytes - always (disregarding alignment and packing). If you create a union containing structures, the size of the union will be that of the largest-sized structure.
The reason the compiler has to use the largest possible size is that the union cannot change its storage size at runtime (just like a structure).
Also there is nothing inside of the union that indicates which data item inside of it is in use. Since this information is unavailable, the space allocated for the union has to use the largest possible size, just in case the largest member of the union happens to be in use, and the the union is passed around to other functions by value (for example). And, even if that information WAS available, there would be nothing stopping the called function from setting a different larger member of the structure, so all of its storage space would have to be there, anyway.
The documentation you read is correct - not all of the members of the union will be being used at the same time - but it says nothing about the storage required for them.
Peace!

Hello,
I want to apply the transcoding of the images using C++.
Background :
As the bigger images with the high resolution are taking a long time to load I want to convert the images into low resolution format and to a restricted size. I am working with c++ and using the GDI+ functions to load the images.
Problem : To apply transcoding of images before actual loading.
Thanks in advance ...
Regards,
Mukta.

Hi,
where you want to load the image? In memory or any control?

Hi,
Thanks for the quick reply.
I want to transcode the image and keep it in the memory first.
As and when the user clicks the thumbnail of that image I want to load the transcoded image in the control.
Regards,
Mukta.

Hi,
AFAIK, without loading the image you cannot do any operation on it. Atleast you have to load it in memory,to do some operations(in your case transcoding).
Transcode the image by keeping it in memory and then display or load it in the control. This will reduce the time delay.
Bye,
Cool Ju
