according to the MSDN on GetObjectSchema:
A CObject-derived class may use VERSIONABLE_SCHEMA combined (using bitwise OR) with the schema version itself (in the IMPLEMENT_SERIAL macro) to create a “versionable object,” that is, an object whose Serialize member function can read multiple versions. The default framework functionality (without VERSIONABLE_SCHEMA) is to throw an exception when the version is mismatched.

HI
In my IMPLEMENT_SERIAL is as follows for both old and new versions:
IMPLEMENT_SERIAL (CFoo, CObject, 1)
then
int nVersion = ar.GetObjectSchema();
is returning -1 that means version is unknown .
now how can i distinguish the versions..
thanks
Regards.

How do I make use of the Microsoft Excel class from my C++ class component to dynamically load and process an excel sheet?

The Fun begins! LOL
You need to use the Excel Object model.
Search the MSDN for these KB's.
KB309301
KB194906
KB308407
KB307473
Just to name a few. These should help get you started. You can also search on "Excel Object Model".
Good Luck!

Hello
Can any one tell me how i can change my console display mode to full screen mode in a dos based c++ program.

You will have to use the SetConsoleWindowInfo function to set the size. But before that you have to use functions like GetConsoleWindow, GetConsoleScreenBufferInfo for the actual effect to take place.

Hi all,
I want to get through a proxy server which needs NTLM authentication.

2) How to set up the headers

Greetings,
I am getting the following warnings. I have some classes whch overide the Create function, but with very different arguement lists. Somehow though the compiler thinks they might be meant to be the same.The arguement lists look very different to me, how can it be assuming they are smiliar?
thanks in advance,
Aristotel

BOOL Create(CWnd* pParentWnd, const RECT& rect, UINT nID, DWORD dwStyle , int nMinVal, int nMaxVal);<br />
warning #1125: function "CWnd::Create(LPCTSTR={LPCSTR={const CHAR={char} *}}, LPCTSTR={LPCSTR={const CHAR={char} *}}, DWORD={unsigned long}, const RECT &, CWnd *, UINT={unsigned int}, CCreateContext *)" is hidden by "CLevelMeter::Create" -- virtual function override intended?
BOOL Create(CWnd* pParentWnd, const RECT& rect, UINT nID, DWORD dwStyle /*=WS_VISIBLE*/, int nMinVal, int nMaxVal);

Try putting virtual in front of the declaration.
EX:
virtual BOOL Create(CWnd* pParentWnd, const RECT& rect, UINT nID, DWORD dwStyle /*=WS_VISIBLE*/, int nMinVal, int nMaxVal);
Hope this helps.

Hi Larry,
Unfortunately that didn't do it. Very strange...such a different arguement list yet it thinks its meant to be an over ride...hmmm...
Do let me know if any other ideas come arround. I will keep looking as well.
Thanks,
Aristotel

Email me your code (all that I need is for compiling) and I will take a look.

Hello Larry...(sorry for the delay)...
The code is part of a rather large commercial project..so i need to try and trim it down to the simplset level so that i can email you the relevant parts.

Has anyone done a comparison between the bog-standard MSVC++ and the plug-in C++ compiler from Intel.
Inital investigations from my team had a stunning decrease in compilation times and some old websearches suggest that the code produced is more optimised.
The version we were trying is available on a 30 license from
http://www.intel.com/software/products/ etc...

Hi,
I am trying to create a XML parser for the VC++ project. The parser needs to parse the xml file and get a specific tag value from the xml file.
Can someone provide me an insight on how to implement it.
Appreciate any help.
Thank you

Thanks.
hi.

There is no requirement that there be any mapping between the uninstall program information in the registry and the location or source of the install program or other related program files.
