Thanks for the response. (Love your articles)
Is 1 enough in these situations or should I really be using sizeof(TCHAR)?
Is the NULL terminator for UNICODE strings just 1 byte? Surely not?

What you have is right. In the code I gave earlier, you aren't adding 1, you're adding 1*sizeof(TCHAR), which is 2 in Unicode builds. The terminating zero in a Unicode string is 2 bytes, the same size as the other characters.
So if you have the Unicode string L"Bob", the byte length is (1+_tcslen(L"Bob"))*sizeof(TCHAR) => (1+3)*2 => 8

to use unicode string, u should forget words "NULL terminator".
there is no such terminator in a general unicode string.

Hi all,
I have a very trivial question regarding float format.
I have the following two statements.
int a = 3.145;
printf ("%f\n", a);
As a result of printf I get 0.0000 why?
I was expecting 3.0000
Any help in this regards
best regards

because if you tell printf that you are giving it a double (%f) then you have to give it a double. it can't perform the cast from int to double for you, because the "..." argument list mechanism that printf uses is not type-safe or even type-aware.
try printf("%f\n", (double)a);

There is no type-checking done on the extra printf() parameters. If you have %f in the format string, it's up to you to actually pass a float variable there. Since you are passing an int, all bets are off.

Two things,
There is no such thing as dumb question, providing the people have done a little bit of investigating first before asking the question.
Secondly, the question forums are only a small part of the CP experience, it is the wealth of articles and information available that make CP stand out from the rest of the crowd.

Here's a way to improve the site - leave. I do harbour concerns that CP is getting cliquey, but a bigger problem seems to be the influx of morons who want us to do their homework and don't want to do any work or participate in the site.

*grin* you may have a point. I'm feeling a little worn out at the moment, work has just been boring, home projects seem to have stalled. But life is better today, I've been moved to the ASP.NET project. I'm stoked.

there is only one MFC usage in it and it's a CString that you can easily replace with const char *.

How can I stop the X from closing the window?
I don't want to disable it, I just want it to hide the window, not close it.

Handle the WM_CLOSE message, and call ShowWindow(hwnd, SW_HIDE) in response to it.

A problem that I see with this method is that another control could not send a WM_CLOSE message and have the window close, you would either have to set a flag in your WndProc to allow it to close at certain times, you would have to out right destroy the window.

Hnadle the WM_SYSCOMMAND message. Execute your special processing where the WPARAM is SC_CLOSE.

does anyone know how i could extract a dialog form so i could use it in another program...
thanks,
grahamoj.

what do you mean by saying "extracting dialog forms"??
could u explain me so I will know whether I can answer your question or not.

If you mean that you created a dialog in a given (old) workspace and you wanna have exactly the same dialog in another (new) workspace without typing it in from scratch than do the following:
1. Create a blank dialog in the new workspace, and close this workspace
2. Go to the old workspce (not in VS but in Windows Explorer) and open oldprojectname.rc file for editing (e.g. with notepad)
Copy the dialog's resources to the clipboard
3. Paste the clipboard in newprojectname.rcto the place where your new dialog was created by VS
4. In resource.h of your new workspace define all resources of the old dialog.
5. Launch VS with the new workspace

The question I ask today is very simple: how do I load icons and text into a ListView control with MFC? I know how to do it in Win32 but as far as I can tell, it's not compatible with MFC ListView control functions.
