When the left mouse button is pressed on a button, the expected behavior is a button click.
Do you not want that behavior?
Is the button not click-able?
If yes, then how do you want it to scroll?

Well. Button is clickable, but i want that my main window recive message wm_mousemove instead of button. I solved it a little while ago with

void MPictureBox::OnMouseMove(UINT nFlags, CPoint point)
{
		CRect pRect;
		CPoint cp;
		GetCursorPos(&cp);
		this->GetParent()->ScreenToClient(&cp);
		LPARAM lParam = ((cp.y) << 16) + cp.x;
		this->GetParent()->PostMessageA(WM_MOUSEMOVE,nFlags,lParam);

}

But anyway thanks =)

C++ templates

I have class A and class B:

template<typename T>
struct A
{
    T data;
    ...
};

template<typename T>
struct B
{
    T data;
    ...
};

I can do the following:

B<A<int> > b1;
B<A<MyOtherType> > b2;

But, these lines are so ugly and I want to make special type. I want to have something like this:

myBA<int> b1;
myBA<MyOtherType> b2;

How I can do it ?
or where I can read about templates like these ?

template<typename T>
struct myBA : public B< A<T> >
{
};

...cmk

The idea that I can be presented with a problem, set out to logically solve it with the tools at hand, and wind up with a program that could not be legally used because someone else followed the same logical steps some years ago and filed for a patent on it is horrifying.

Yes, I know that approach. But I wanna have another way, without declaration of new class.

You can write it as one line of code, do you expect to find something shorter ?

What's wrong with declaring a new class?
That's what you asked for.

Here is one way to do it.

typedef A<int> IntA;
typedef A<MyOtherType> MyOtherInt;

B<IntA> b1;
B<MyOtherInt> b2;

Or you could go one step further.

typedef A<int> IntA;
typedef A<MyOtherType> MyOtherInt;

typedef B<IntA> myIntBA;
typedef B<MyOtherInt> myOtherBA;

myIntBA b1;
myOtherBA b2;

You could also make the above into a single typedef.

typedef B<A<int>> myIntBA;
typedef B<A<MyOtherType>> myOtherBA;

myIntBA b1;
myOtherBA b2;

I assume you checked with google before ? there are couple of hits with source code, maybe not c++/vs2008, but nothing preventing you to look at them and convert them.

anyway, good luck.

Thanks for your replay Sir ...i tried means ...i build some sample application from codeproject but its not creating 16 bit bmp ....

this is my workout

actually this application do's Converting DCM 2 BMP ... i can able to convert 8 and 24 bit ..its creating perfectly ..using DCMTK package but 16 bit bmp its having problem ....

this is my code snippet

bool CxImageDCM::LoadDCM(const TCHAR* filename)
{  
	DcmFileFormat *dfile = new DcmFileFormat();
    OFCondition cond = dfile->loadFile(filename, EXS_Unknown,
		EGL_withoutGL,DCM_MaxReadLength,OFFalse);
	
	if (cond.bad()) {
		AfxMessageBox(cond.text());
    }
	
	E_TransferSyntax xfer = dfile->getDataset()->getOriginalXfer();
    DicomImage *di = new DicomImage(dfile, xfer, 
		CIF_AcrNemaCompatibility ,
		0, 1);
	
	if (di->getStatus() != EIS_Normal)
        AfxMessageBox(DicomImage::getString(di->getStatus()));
	di->writeBMP("D:\\Esm.bmp",8,0);
	return CxImage::Load("D:\\from_dicom.bmp",CXIMAGE_FORMAT_BMP);
	
	//return 0; // Code 
}

Please give me your valuable suggestion ....sir i am waiting for your replay ..

Well, you may obtain a 16 bit bitmap from a 24 bit one: it's a quite lenghty coding task, but it isn't too difficult (starting point: CreateBitmap documentation [^]). If you ahve the option of using GDI+ then have a look at Bitmap::ConvertFormat method [^].

Maybe you can write a program to put bytes of random values to the unused space of the disk, for example, by creating a large file that fills the whole disk space. That will erase all deleted files, I believe.

That works as long as he erases the files he wants to delete (using his application.) If the program wants to erase all the deleted files and folders (they might be deleted by other programs) it still needs a way to get rid of all the traces of those files on the disk.
