Copy these bits to long variable or in some other string.For different cases, I need to copy the bits in to different type of variables.

Thanks,

// bits from 3rd to 27th (i.e. I guess, bit 2 to 26)
const char s[]="foo"; // string size must be at least 4
int i= (*(int * )s) & 0x07FFFFC;

If you have a CString then you can use the GetAt() function. Here's a link to an msdn page with information about basic string operations:-

And here's one about GetAt():-

Hi Alison,

I want to copy bits from string not byte. It can be starting from 4th bit of first byte to 5th bit of 6th byte.
GetAt is for bytes.

Thanks

Once you have a byte you can extract the bits using a struct & union, this answer from CPallini gives you a great example ...

You restrict your window's size by handling the WM_GETMINMAXINFO message.

LRESULT OnGetMinMaxInfo ( WPARAM wParam, LPARAM lParam )
{
MINMAXINFO* pmmi = (MINMAXINFO*) lParam;

pmmi->ptMinTrackSize.x = 100;
pmmi->ptMinTrackSize.y = 150;
pmmi->ptMaxTrackSize.x = 600;
pmmi->ptMaxTrackSize.y = 400;

return 0;
}

I cannot get OnGetMaxMinInfo as LRESULT
it looks like this only

void CChildFrame::OnGetMinMaxInfo(MINMAXINFO* lpMMI)

Remove the relevant styles from the target window:

DWORD dwStyle = ::GetWindowLong(hWnd, GWL_STYLE);
DWORD dwRemove = WS_CAPTION | WS_SYSMENU | WS_MINIMIZEBOX | WS_MAXIMIZEBOX;
DWORD dwNewStyle = dwStyle & ~dwRemove;
::SetWindowLong(hWnd, GWL_STYLE, dwNewStyle);
::SetWindowPos(hWnd, NULL, 0, 0, 0, 0, SWP_NOSIZE | SWP_NOMOVE | SWP_NOZORDER | SWP_NOACTIVATE | SWP_FRAMECHANGED);

You may just use

DWORD dwNewStyle = dwStyle ^ dwRemove;

there.

You're the only one that seems to know anything about creating a full screen in Win32. I know I asked before in a different thread, but there is really no documentation about how to hide the app menu that I create in the resource file. I have tried ending it by using EndMenu, destroying it with DestroyMenu(), but nothing seems to work. Do you have any idea?
