CBitmapCtrl: Control for Displaying Bitmaps
Environment: VC6, Windows 95/98/NT
Its name is CBitmapCtrl and it is a class representing a dialog control that loads bitmaps from files. The fancy thing (that I've not seen in other related postings) is that this control does not clip the bitmap if it's bigger than the control's window - it uses scrollbars for the user to be able to see the whole bitmap.
You can use it very easily:
void SetBitmap(HBITMAP hBmp);
is the member function that loads a bitmap from HBITMAP
void LoadFile(CString filename);
is the member function that loads a bitmap from a file name.
To create the control you need these lines of code:
CRect brect;
GetDlgItem(IDC_BITMAP_CTRL)->GetWindowRect(brect);
ScreenToClient(brect);
m_bmpCtrl.Create(WS_CHILD|WS_VISIBLE,brect,this);
m_bmpCtrl is a the CBitmapCtrl member variable.
