Hello all!
I have a little problem in my project (VC++ 6.0).
I want to show user a dialog box with question "exit app or not" when he tries to close application.
Where shoult I write a handle to this event?
Thank you!

I believe you can do this by overriding the default OnClose() method (WM_CLOSE message)in the main frame window of your application. Then call the CFrameWnd::OnClose() method if the user clicks "OK".

how will you differ if user clicked exit or the computer is going shutdown? a message box would than be totaly anoying.

After I hit reply to your question, I realized that I have forgotten the code I wrote yesterday night to create folders.  But I am sure there is one.
Sorry.

For what?

hi,
3 questions.
1.how to display symbols in listbox text like the wave equation?formatting the string using the ascii octal just gives a box in place of the symbol.
2.how to add tabs in a string and not get black boxes when displayed in a list box.
3.how to set the precision for floats.i have to display say 1.23 and not 1.23046.
where can i find good illustrated examples of printf family?
thanx.

1. I presume you need to owner draw
2. \t is a tab, if it won't show, the answer again is owner draw
3. ostringstream will do that for you, so will printf, you can use printf if you don't care about safety, or if you're especially worried about exe size.
examples of printf abound in the MSDN.

1. you'll probably have to draw them yourself (see "owner-drawn" listbox)
2. see 1, or replace the tabs with spaces
3. MSDN, any book on C, etc.. but, if you want to limit the number of decimal places, use this notation: %.3f . this will give you three digits after the decimal.

1. there is no such thing as "visual c"
2. C# is a new language that is similar to C++ and Java

One is a new language that is based strongly on C++, VB and Java, the other is a common contraction where Visual C++ is meant. Visual C++ is an IDE from Microsoft for programming in the C++ language.
Why do you ask ?

I am trying to get a certain date variable to be converted to a text so I can then display it in the window of my windows program. Any suggestions will be accepted.
Thanks

ostringstream will do it, and I have an article on CP that explains how.

LOL
1. Get an account here so that people will take such a question remotely seriously.
2. If you don't know what it is, why do you want to learn it ?
3. As Chris said above, there is no such thing as Visual C. You probably mean Visual C++, and you probably want to learn C++. If you don't know what it is, you'd be better off with VB, where you can't hurt yourself.

He/she may not hurt him/herself but is quite likely to hurt others. Surely it's unwise to recommend VB even in such a circumstance as this??

I couldn't think of anything worse. Logo, maybe ?
