Is it possible in an MFC/MDI application to prevent the last window from being closed e.g. if someone accidentally clicks the 'X' on the lat window?
TIA
|
|
|
|
|
yes you can.
just overloads the WM_CLOSE event (OnClose() event handler)

[toxcct][VisualCalc]

Thanks for the reply.
Is it the child frame OnClose() that I should overload?
TIA
|
|
|
|
|
it is the OnClose of the Dialog you want to prevent from closing... (the child if it is the child...)
TOXCCT >>> GEII power
[toxcct][VisualCalc]

Just overload the OnCancel() event hadler as toxcct told you
and write the following inside
void CYourDlg::OnBnClickedCancel()
{
if (MessageBox("Are you sure to exit ?","msgboxtitle",MB_YESNO|MB_ICONQUESTION) ==IDYES ) OnCancel();
}

When I rotate my bitmap to a degree which is not a multiple of 90 the size of the image increases to accommodate the new rotated bitmap. E.g. 45 degrees
My problem arises, when I rotate an image of resolution 768*576 the new size increases drastically. Will it be logical to rotate and then resize the bitmap back to the original size for every rotation?
I have also tried using XForm, it works great but it does not allow me to save the rotation. Is there an alternative. If not, where do I find an algorithm to resize a
24- Bit Bitmap.

Hello!
I'm testing and writing my documentation.
I do not know how to calculate minimum configuration for the program.
Thanks
|
|
|
|
|
Is it for a game or application?
When testing for a game, check which configuration is needed to play the game at minimum resolution (800 x 600 or something like that) at least at 25 fps.
See how much memory (ram) your application is using. If it is more than 16, users should have at least 32 (because other applications are using ram too).

My goal is to create a dll that exposes some functions (from my classes).
This newly created dll is then going to be consumed by another application.
Don't know if a tlb-file is the right thing to do, but i've earlier imported oters tlb-files but never created my own one...

I have a .dll and .lib that are created by Borland CBuilder. And I want to use these two files in Visual C++. However, directly adding these files into my VC++ project generates error once I call any functions in the .dll.
What should I do so that I can re-use the Borland CBuilder .dll and .lib files in VC++?

Hi,
I am writing a software which generates a unique machine id for a machine based on hardware/software components.
Currently i am using the following parameters - mac address, windows serial key, c: volume info and cpu id.
I am in need of some more paramters like HDD id, Motherboard ID, CDROM-Drive id.
Is there any solution which possibly doesn't use MFC or read the registry ?

Why not just use CoCreateGuid() instead?

Hello Friends,
I have virtual function in my class and I don't want the vtable to be created. Can anybody help regarding this one. Is there any method for the above problem or any keyword, which helps the programmer to avoid creating vtable for the class.
Thanks in advance,
Neelesh K J Jain.

No. If you have a virtual function, there must be a vtable.

I doubt you can do anything of that,
but incase if you were able to then your function would lose its advantage of being virtual and be as good as any other functions of your class.
If that's ok then why not to remove the virtual keyword of the function.

 Why you don't want to create VTABLE?, Any specfic reason!

Actually I had been asked this question in one of my interview recently. My feeling is that if we could be able to avoid creating of Vtable, then I agree with the reply of Nilesh.
No use of having virtual functions itself.
So, I just wanted to know whether we can avoid creation of vtable, then how?
