If you're using VS 2008, you could download and install the MFC Feature pack for Visual C++ 2008[^]. The MFC library has been enhanced to support feature rich UI with office ribbon control, and other funky stuff. I've not used that much, but there are some sample projects that can be downloaded from MSDN.

the skin of the point cloud from top view in C++

cstic10-Oct-09 11:22

The file format is defined as followed:
• Every line contains one point
• The point definition contains x, y and z coordinates delimited by a space character
• Each line is ended by the new line character
Please note that only “visible” points from top view must be written to the file (the skin of the point cloud from top view) (Illustration 4).
Given:
1. Point class for the definition of a point in 3d and (some) methods for vector algebra
2. Strictly use of STL and C++ stream library
3. Visual C++ 6.0 or .NET as a development environment
4. High level test function to test the resulting component. This defines also the “interface” of the component to be written.
Hints:
- Create a small documentation 1 page with 2 pictures to present the mathematical approach of the sphere move point intersection. It should clearly communicate the mathematical approach and how the “mathematical” code is generated from that
- Use of vector algebra (dot product, cross product etc.) is highly recommended. The use of sin and cos functions is not desired.
Calculation speed is important but secondary in comparison to a good object oriented approach. E.g. a sphere, linear move of a sphere, point writer etc. should be modeled as classes. Try to use many of compact classes instead of large classes and large functions.
- Comments in the source code are welcomed. Please use “good” names for classes and functions.
- Move of a sphere between f (t) and f (t  Δt) can be assumed as a linear move of the center of the sphere.

Hi Daniel,

You can have your hook procedure in a hidden window that is not in the minimized state. However... why can't you just call the GetLastInputInfo Function[^] to determine the users idle time?

Hi,

I'd like to how caputre scrollview area, incluing unvisible area...
scrollview size is nomally big than actually monito's resoluton, unvisible area don't captured...

CRect rect;
HWND    hWnd = m_hWnd; // m_hWnd is hanle of scrollview.
if (hWnd == NULL) return;

HDC hScrollView = ::GetWindowDC(hWnd);
HDC hCaptureDC = CreateCompatibleDC(hScrollView);

CRect m_rDrawingSurface;
::GetWindowRect(hWnd,&m_rDrawingSurface);

BITMAPINFOHEADER BMIH;
HBITMAP m_hCaptureBitmap;
BYTE* m_pDrawingSurfaceBits;

CDC* pDC = GetDC();
if(pDC != NULL)
{
    BMIH.biSize = sizeof(BITMAPINFOHEADER);
    BMIH.biBitCount = 24;
    BMIH.biPlanes = 1;
    BMIH.biCompression = BI_RGB;
    BMIH.biWidth = m_rDrawingSurface.Width();
    BMIH.biHeight = m_rDrawingSurface.Height();
    BMIH.biSizeImage = ((((BMIH.biWidth * BMIH.biBitCount) + 31) & ~31) >> 3) * BMIH.biHeight;
    m_hCaptureBitmap = CreateDIBSection(pDC->GetSafeHdc(), (CONST BITMAPINFO*)&BMIH, DIB_RGB_COLORS, (void**)&m_pDrawingSurfaceBits, NULL, 0);
    ReleaseDC(pDC);
}

SelectObject(hCaptureDC,m_hCaptureBitmap);
BitBlt(hCaptureDC,
    0,
    0,
    m_rDrawingSurface.Width(),
    m_rDrawingSurface.Height(),
    hScrollView,0, 0,SRCCOPY|CAPTUREBLT);

CxImage *image = new CxImage();
if(m_hCaptureBitmap)
{
    image->CreateFromHBITMAP(m_hCaptureBitmap);
    bool retval;

    retval = image->Save("c:\\ss.bmp", CXIMAGE_FORMAT_JPG);

I am going to implement smart card using VC++.
i am using SCM dual interface reader SDI010
having standards ISO7816 And ISO14443 (type A and B).
Can someone tell about some sample code that can provide me help that how can i read from and write into a smart card..

Thanks in advance

Maybe a call to UpdateWindow() is in order.

How to restrict a class not to create more than 3 objects?

Re: Class Object

Rajesh R Subramanian9-Oct-09 23:21

Handle the construction yourself - make the constructor private and provide a public static method to create an instance of the class. Keep a data member to maintain the count of currently active objects, which should be a maximum of 3. Increase it with every construction and decrease it in the destructor.

You could try this, although it's NOT thread-safe

class Restricted
{
public:
   Restricted()
   {
      if (instances==3) throw SomeException();
      instances++;
   }
   ~Restricted()
   {
      instances--;
   }
private:
   static int instances;
};

// In the class's .cpp file, 

int Restricted::instances = 0;

Hi,

I am just giving you simple way, try it.

class resritct
{
 public:
 restrict(){}
 void show(){ cout<<"restricted class"; }
};
void main()
{
 // Here I am writing for restricting the object creation.
 //object genration
 for(int i=0;i<3;i++)
  {
   resrict r;
   r.show();
  }
 }

Calculate the composite width and height of your dialogs and make sure the client portion of your window is exactly that size. As you create each dialog move it to the appropriate quadrant of the window.

You can dynamically create 4 dialogs, here is to create a dynamically child dialog:

<br />
// new a child dialog from the heap memory<br />
CRect rect;<br />
CChildDlg *pDlg=new CChildDlg();<br />
 <br />
// create a child dialog,and get the window rect.<br />
pDlg->Create(IDD_ChildDlg,NULL);<br />
pDlg->GetWindowRect(rect);<br />
 <br />
// move it to point x =10, y =20<br />
pDlg->MoveWindow(10,20,rect.bottom,rect.left,TRUE);<br />
 <br />
// show and update the child window<br />
pDlg->ShowWindow(SW_SHOWNORMAL);<br />
pDlg->UpdateWindow();<br />
pDlg = NULL;<br />

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
