CFont clean-up
-
Hi, Please can you tell me the correct way to perform clean-up operation for a
Cfontobject? I use this in OnInitDialog() :CFont *m_pTitleFont = new CFont;
m_pTitleFont->CreateFont(25,0,0,0,800,0,0,0,0,0,0,ANTIALIASED_QUALITY,0,"Verdana");s_Title.SetFont(m_pTitleFont);
s_Title is a CStatic object. I use different font types for different Static controls. So I am usually creating three-four fonts. Thanks.

How about delete m_pTitleFont; ? Mark

I wonder if the
CFontdestructor calls theDeleteObjectmethod, does it?If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler. -- Alfonso the Wise, 13th Century King of Castile.

Not directly. ~CGdiObject() does though. Mark

OK, thanks! :-D BTW this MS sample made me wondering about [^], since they explicitely call
CFont::DeleteObject.If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler. -- Alfonso the Wise, 13th Century King of Castile.

You can look in the source and find out.....

What an empirical boy!:-D Do you suggest to take sources as references? They're of course, for the current release... and..what if MS changes mind over time? :)

They are not going to change something like. They can hardly make the class not clean up the resources when it previously did of vice versa.

I agree on the above observation, of course.:) I don't agree on the method, of course.:-D

In a perfect world the documentation would be complete and answer all your questions. In the real world this is not always the case and you often need to find your answers elsewhere. In such situations a mixture of common sense and a peek at source code often save the day. This is just life in the trenches.

That's cool. The OP created his/hers with new so I chose delete as an idea :) For a local object, DeleteObject is great to free the HGDIOBJ when you no longer need it. When the CFont goes out of scope, it will be freed as well. Cheers! Mark
