BOOL RedrawWindow(
HWND hWnd, // handle to window
CONST RECT *lprcUpdate, // update rectangle
HRGN hrgnUpdate, // handle to update region
UINT flags // array of redraw flags /// Try using a combination
);

Somethings seem HARD to do, until we know how to do them.

A WORD is a 16 bit unsigned integer. use %u for that

hi,

"%d" -> Signed integers
"%u" -> UnSigned integers

as BYTE is unsigned type use "%u"

ownerdraw round button question

HOW WHAT4-Jul-06 18:02

I create a CMyButton and handled WM_SIZE

void CMyButton::OnSize(...)<br />
{<br />
	CButton::OnSize(...);<br />
<br />
	CRect rect;<br />
	GetClientRect(rect);<br />
<br />
	m_rgn.DeleteObject(); <br />
	SetWindowRgn(NULL, FALSE);<br />
	m_rgn.CreateEllipticRgnIndirect(rect);<br />
	SetWindowRgn(m_rgn, TRUE);<br />
<br />
}

But when the button size changed, round size not change, why?

Thanks.

"Need to change the values in the rect" how to do?

_AnsHUMAN_ 4-Jul-06 19:29

rect.top = 20; etc . Do likewise for rect.left,rect.right,rect.bottom

i want "when button size is changed, the round size same with button size"

_AnsHUMAN_ 4-Jul-06 19:56

Instead of the code that you are writing try this.

void CMyButton::OnSize(...)
{
CButton::OnSize(...);
CRect rect(10,10,30,30);
m_rgn.DeleteObject();
SetWindowRgn(NULL, FALSE);
m_rgn.CreateEllipticRgnIndirect(rect);
SetWindowRgn(m_rgn, TRUE);
}

I hope this helps

Hi ,

HOW WHAT wrote:
CRect rect;
GetClientRect(rect);

I'm not sure , but according to MSDN , GetClientRect()
gets as parameter the pointer to the rect , and not the rect
itself :

CWnd::GetClientRect  
void GetClientRect( LPRECT lpRect ) const;

So try the following instead :

CRect rect;
GetClientRect(&rect);

Hopes this helps ,

Eli
