Brilliant cheers 
my next question is about the pointer to the window hWnd. How can I get a pointer to whichever dialogue creates an instance of my serial port class? e.g. I have a communications dialogue and I want to get a handle to this but using my serial port class, but make it flexible so that it is not restricted to one dialogue?
Thanks

It would be up to the class that creates an instance of your serial port class to provide a pointer to its window. Your serial port class cannot "reach out" and get this.

Ok, so the Dialogue class could pass it's own pointer if I defined the interface to the config dialogue as something like
CComPort port;
port.config(hWndDialogue)
but how do I get the handle to the dialogue window? THis is what I meant really in the first place, I thought about using GetParent on the Config dialogue , but I can't because I need to create it first! Sorry if this is a stupid question. Hope you can help

hWndDialogue IS the handle to the dialog window. I'm assuming this only because you are using a variable-naming convention where 'h' most likely means handle.

ok, I have worked out that I needed to use the m_hWnd member of my dialogue doh! i.e. pass
port.config(m_hWnd);
How can i find out what member variables are in a class heirarchy? The base classes viewer seems to only show functions?

Not sure. Are you talking about the ClassView tab in the Workspace window? I've never known it to NOT show all members of a class.
|

Yes the class view shows the members you declare in your derived class, but I don't think it shows the member variables in the base classes i.e. CWnd member variables.

Nor would you want it to. The Workspace window would be way too crowded then. Intellisense, however, will show you the complete list of whatever object you happen to be working on.

Although I am not very versed in that topic, what kind of "data" do you mean?
Are you trying to read the RAW CD-Rom data, audio or just the files in the disk's standard file system that can be accessed by Windows itself, for example?
For the third case, have a look at CFile, CArchive, CStdioFile, ... in the MSDN. Maybe Windows just handles the files as if they were on a hard disk, but only write protected.

hi,
i cant find any examples on CodeProject or on MSDN, so does anyone know if/how to display pictures or icons along with text inside of a combobox?
Thanks

Check out CComboBoxEx. This may not do exactly what you want, but it is a good example to adapt.

Or, you could do it the old-fashioned way via ownerdraw.

Make sure WINVER is #define'd to be 0x0500 or higher before including "windows.h"

Why do I need to enter this into my "Project/settings/links/output,entry-point" box to avoid getting error messages when I go to compile a simple Win32 application? I have to do this for every application, is this normal?
Thanks
