I didn't realy.;) I just thought the no-hook requirement to restrictive. The enumeration process will probably be slow and may still require a seperate thread to raise an event.

I've spent time searching and found nothing, that did not use hooks. Frown | :(

As Nish works for Dundas, it might be something for one of their classes and the rule would be due to the fact that they don't want to install a hook on a client machine.

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!

actually, my VisualCalc 2.13 uses simple doubles for now...

if he had wanted 128 bits integers, he could have used __int64, but for floating point numbers... WTF | :WTF:

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();

// your operations
private:
    void* m_pData;
};

// overloaded operators
CFloat128 operator + (const CFloat128& lFloat, const CFloat128 rFloat);
// etc..

Hope this helps Smile | :)

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?

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.

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.
