A map file is a file that contains all of the address information (and other stuff) about your code, either in the form of an offset from a starting location, or the actual runtime value. I use map files to get the addresses of exported variables in my VxWorks embedded code.

hello,
I'm developing an application that should be able to display names of people from various corners of the world (ie, lots of languages at once). For that, I'd really like to be able to create a font that could handle all the unicode characters (or at least some kind of roman alphabet subset, but with all the punctuation and stuff, so that ie. Goethe would spell Gothe with an umlaut etc). I'm not sure such fonts are even installed (WXP).
I tried CreateFontIndirect, but since not even the LOGFONT structre has any attribute that would take "make it a unicode font", I don't know what to do next (and I really don't want to store language informoation and create multiple fonts etc). Any hints?
PS: I also tried looking at unicode.org, but still I'm unable to render most of the fonts

Send a message with SendMessage to the other dialog, process that message in the other dialog.
If you want to do it cleaner, you can use a registered message.
Hope this helps.

|
|
|
if we suppose CMain is dialog1 and Local is dialog2 you can use CMain *m_Main=(CMain*)GetParent(); m_Main->m_StaticControl
|

Having a dialog interact with controls it does not own is a bad design. Post a message to the second dialog instead.

I've built an SDI application without problems, adding classes. When I've linked a thirdy party library i've had to change compiler switch from Multithreaded (/MT) to Multithreaded DLL (/MD) and adding the _AFXDLL symbol to properly compile the entire project. The project is linked with the shard version of MFC.
When the application exits, i've noticed a lot of memory leaks and that classes destructors are not invoked (CView derived class and CMainFrame destructors are invoked, but CDocument destructor and other
classes destructors are not invoked).
I can't understand the causes of this problem and if the /MD compiler option is one of them.
Any idea ?

Take a look at where and how you create an instance of the class. The probable cause is that you have created an instance somewhere with the keyword new, and you are failing to call delete. If that class has other classes as members, their destructors will in turn fail to be called.

Dear all
I Write one class in Visual C++ which is responsible for logging of stream data.
This Class is used in a dll which is used to contact to hardware.
I want to enable the logging capability in some special times.
But Because this class is used in a dll file, I can not access it via keyboard or mouse. (I dont access the program that uses my dll.)
thus I need an interface to inform my class to enable or disable logging process.
for an example I can create a file in a special place, and my class check the existence of that specific file as a sign of logging permission.
But this solution is not professional.
Thus please send me your idea about this problem.
Thanx in advance
Mahdi

Depends a lot of how you 'use' your dll. Is this class exported by your dll ? If yes, simply treat exactly the same way as if it was part of your application (so, add a function in the class to enable or disable the logging). If it is not exported, you can still export a function in your dll that will allow to enable or disable the logging.

Can you explain this? To able to use your class that logs. There should be some application that uses it?

Can you modify the EXE that uses your DLL?

It's not supposed to be. That's why it's a special ID.
Why can't you just give your static control a different ID?
