Actually it's C++ code in MFC ;)

CStatic is a MFC class (WIN32 doesn't have wrapper classes). And C doesn't have classes neither. So CQFD :-D

m_hbmp=m_vicImg.hBitmap;

Assigns to this object's (a CDialog derived class?) m_hbmp member (probably a HBITMAP, i.e. a Bitmap handle) the value of m_vicImg.hBitmap (i.e. the member hBitmap of the m_vicImg object (that you only know and probably is another member of this object).

CStatic *pImgPicture=(CStatic*)GetDlgItem(IDC_staImg1);

Gets a pointer to a CStatic object representing the dialog static control having ID equal to IDC_staImg1.

pImgPicture->SetBitmap(m_hbmp);

Calls the SetBitmap method of the CStatic object. This should change the bitmap represented by the dialog static control. BTW You can also get some information reading MSDN documentation. :)

You can declare a variable for static control instead make a pointer.
