I want to perform some calculation which require extremely large floating point values i.e. > 1.7e308. I want some class for handling such large calculations. 128Bit or more.
Any tips would be welcomed.
Thanks!

May be you can get some help with this link.

actually, my VisualCalc 2.13 uses simple double s for now...
if he had wanted 128 bits integers, he could have used __int64, but for floating point numbers... i really don't know.

Hello,
You could always create a class that holds a memory block of 128 bits. You have to decide which floating point representation you use and define all the basic operations yourself. You have to go down to the bit level yourself to do all the excact calculations.
One class declaration could look like:
class CFloat128
{
public:
CFloat128(unsigned __int64 uLowOrder,
unsigned __int64 uHighOrder = 0,
bool bNegative = false);
~CFloat128();
private:
void* m_pData;
};
CFloat128 operator + (const CFloat128& lFloat, const CFloat128 rFloat);
Hope this helps

Respected all
Regards!
I have 2 bitmaps i.e
m_sBitmap1="C:\\abc.bmp" //large in size
m_sBitma2="C:\\xyz.bmp"//having small size.
now i have to load both bitmaps in the form that small bitmap(xyz.bmp) display on a specific position on the large(abc.bmp)bitmap as i want.and then both bitmaps visible to me.
plz guide me with source code.

Where you would like to display second bitmap?
Under first bitmap?
To display bitmap see this link.

Respected haranadh
I want to dispaly 2nd bitmap somewhere on first bitmap where already some place is reserved of the 2nd bitmap and also i have X and Y position for the 2nd Bitmap,but how to do it ,plz push me.

hope things will now clear to you.

A bitmap becomes a drawable surface if selected into a device context.
Essentially, given a "screen DC", you can create two memory DC with CreateComaptibleDC and then select the bitmaps in their respective DC.
A that point, the content of a DC can be painted over the other with the BitBlt function.
Depending on the framework you are using, those Win32 functions are wrapped in appropriate classes (MFC or WTL have their own - see the respective documentation).
Don't forget to restore the DCs to their original content before destroy them.

Infact I want to use Setup API and some other s of DDk which are declared in "cfgmgr32.h".
So Please tell me what should I do to overcome this problem.
Thanks.

It would help it you told us what "C++BuilderX" is. Presonaly, I have never heard of it.

i don't what the Mobile App sample is supposed to be, but if it uses MFC or Microsoft specific classes, you cannot compile with a compiler that don't have the source of the libraries...
i don't know how C++BuilderX works, so a cannot tell you wht these eror messages refer to... see the doc of you compiler/linker (maybe) for that.

Make this question in a Symbian forum, like www.newlc.com. By the way, it is not a good idea (and not very polite too) to keep crucial information hidden from the people you are asking to help you.

Hello all, I recently compiled a release build of a project and ran into initial problems that would cause the application to fail. After correcting these problems (program appears to function properly w/ no crashes), I decided to send it to some friends to test out. On the first attempt, my friend reported he receive a msg asking for MSVCPP70. Thinking that this might be a MFC dll issue i went into my project settings and set the option to use mfc in a static library. After doing this, my program will run, except for a feature which communicates w/ a server via a worker thread. The odd thing is... the application runs flawlessly on my own system.
What issues do you think I am running into? Are there dlls that i should be coupling w/ my release build?

It's hard to say from the info you provide...

So, what happens with that feature? Does it give some error (which)?

Sounds more like a firewall/network problem to me. Where is the server located? Is it accesible from your friend's PC?
