Can you at least show the relevant code?

Most decidedly, this has nothing to do with CFile itself, but that you're doing something wrong. Can you show us your code?

Without seeing your code, most likely you're trying to open the file with read/write access, which will fail. If you show your code, perhaps we can be more helpful.

Hi
I used following code to replace my application menu.
CMenu mu;
mu.LoadMenu(nMenuID);
SetMenu(&mu);
DrawMenuBar();
The new menu was loaded. But whenever I tried to get MENU Handle, I will get an assertion error.
CMenu* pMenu = GetMenu();
HMENU hmenu = pMenu->GetSafeHmenu(); --->Assertion error.
How can I solve this?
Thanks,

I'm not an expert about, but I suppose in not a good idea using a CMenu temporary object.
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

Apparently[^], using a local object is the canonical way to set a menu, but CMenu::Detach()[^] nneds to be called before the temp object goes out of scope.
Ah, the beauties of MFC

Of course, the canonical way depends on the documentation author of the moment... [^].

OK, I just read this post.
Well, I see that MFC is *actually* beautiful. One mistake is that most frequently done by newbies is putting a CFont object on the stack, setting the font of a control with this, and then wondering why it "didn't work". But they'll eventually get things to work and will appreciate the framework.

Is mu local or does it have class scope?
What line of what file is asserting?
"Old age is like a bank account. You withdraw later in life what you have deposited along the way." - Unknown

The Debugger did not guide me to there.
Thanks

Assertions have nothing to do with the debugger. When an assertion fires, you'll see:
Assertion Failed: File %hs, Line %d
"Old age is like a bank account. You withdraw later in life what you have deposited along the way." - Unknown
"Fireproof doesn't mean the fire will never come. It means when the fire comes that you will be able to withstand it." - Michael Simmons

atlmfc\include\afxwin1.inl: Line 900
Thanks,
|
|
|
|

So did you look at line 900 of afxwin1.inl to see what condition is asserting?
"Old age is like a bank account. You withdraw later in life what you have deposited along the way." - Unknown
"Fireproof doesn't mean the fire will never come. It means when the fire comes that you will be able to withstand it." - Michael Simmons

{ ASSERT(this == NULL || m_hMenu == NULL || ::IsMenu(m_hMenu));
I think the menu was destroyed.

Does not return a CMenu*. You should be calling CWnd::GetMenu().

It does if called in the context of a CWnd-derived class.

My (mis-)reading of the documentation implied that you had to call this on a CWnd object reference.

After the call to SetMenu() you need to call mu.Detach() so the destructor does not destroy the handle.

Hello,
I am developing multilingual MFC application.
My application has very heavy GUI, and I want to create resource DLL for each language, which my application load at run time when needed.
So I want to make resource DLL for application per language which just contain "string table" nothing else, and remaining resource should use from application default resource.
Basic requirement:
1) Don't want to redundant Image, Dialog and Menus in each resource DLL.
Can anyone suggest way for same?

You just need to create a resource set comprising strings only. If there are any other auto-generated items they can be deleted.

Thanks Richard,
But I want to in a way so I no need to do any compilation and code change to support new language. Thats way i was preferring separate resource DLL.
What is your view/solution?
