I want to use the class CList for my project, but I get the following compiler error as soon as I do #include <afxtempl.h>

Compiling...
snaplogger_main.cpp

Not a real error, but only an information.

Do you include Windows.h anywhere explicitly?
How does the stdafx.h of your project look like? Where do you include afxtempl.h?

I do not see any stdafx.h in my project. And no, I do not include Windows.h explicitly.

afxtempl.h is included in CDeviceFileParser.h

Any idea of why windows.h is being included? And why should this be a problem??

What kind of application did you create? Is it a MFC application? Seems so since you intend to use afxtempl.h. Can you please check the the project settings?

I am not very sure if it is a MFC application, I did not create it myself.

Project properties says:
Use of MFC : Use Standard Windows Libraries

Maybe it would be the easiest way to create an empty MFC project and add the files of the Win32 project to that?
Or simply try to change the "Use of MFC" to "Use MFC in a Static library" and rebuild. Don't know if this will work.

Oh... I've just found a place where windows.h is included explicitly. What a mess!! I should start tidying all this up first of all...
Thanks!

Do you have an MFC-based project? If not, you might consider using one of the STL containers instead.

I might be easier if I say what I want to do.

I want to store in a variable a number of strings. The number of them will be variable and not known at the time of declaring the list/array/whatever.

For what I have been reading I can do it with std::list, although I've never used it before.

True, as well as std::vector.

This problem probably sounds silly but I can't get my head round it; there it goes:

#include <DelimFileParser.h>
int a;    //I can't define any type of variable in here
typedef struct
{
	std::string m_devTrainId;
	std::string m_devIp;//sockaddr_in
        ...

The compiler's message:

Linking...
CDeviceFileParser.obj : error LNK2005: "int a" (?a@@3HA) already defined in CCommsManager.obj
CSnapLogger.obj : error LNK2005: "int a" (?a@@3HA) already defined in CCommsManager.obj
snaplogger_main.obj : error LNK2005: "int a" (?a@@3HA) already defined in CCommsManager.obj

snaplogger_main.h includes CSnapLogger.h
CSnapLogger.h includes CCommsManager.h
CCommsManager.h includes CDeviceFileParser.h

If you want to use this variable only in this source module then add the static keyword thus:

static int a;

Just say 'NO' to evaluated arguments for diadic functions! Ash

Thank you!

If you want a global variable to be accessed from all files, make the definition in the source file (.c, .cpp etc.) instead of a header file.
In the header do a declaration like this - extern int a;
