How to handle lost focus in DrawItem of Button

Hi all,

This is the code, I've written in my Button class:

void CMyButton::DrawItem(LPDRAWITEMSTRUCT lpDrawItemStruct)<br />
{<br />
   CDC dc;<br />
   dc.Attach(lpDrawItemStruct->hDC);<br />
   CRect rt;<br />
   rt = lpDrawItemStruct->rcItem;<br />
<br />
   UINT state = lpDrawItemStruct->itemState; <br />
   if ( (state & ODS_SELECTED) )<br />
      dc.DrawEdge(rt,EDGE_SUNKEN,BF_RECT);<br />
   else<br />
      dc.DrawEdge(rt,EDGE_RAISED,BF_RECT);<br />
	<br />
   dc.SetTextColor(m_colText);<br />
<br />
   CString strTemp;<br />
   GetWindowText(strTemp);<br />
<br />
   dc.DrawText<br />
      (strTemp,rt,DT_CENTER|DT_VCENTER|DT_SINGLELINE);<br />
<br />
   if ( (state & ODS_FOCUS ) )<br />
   {<br />
	int iChange = 3;<br />
	rt.top += iChange;<br />
		rt.left += iChange;<br />
		rt.right -= iChange;<br />
		rt.bottom -= iChange;<br />
		dc.DrawFocusRect(rt);<br />
   }<br />
   dc.Detach();<br />
}

The focus rectangle is still there even it is lost the focus. How should I handle this ?

IMPORTANT

If you could see my previous post, titled "MDI and ResizeParentToFit()", and give your thoughts, it would be more helpful.

Hi inculdeh10 & WhiteSky,

I missed the the following code. Thats why I got the focus rectangle always.

dc.FillSolidRect(rt, GetSysColor(COLOR_BTNFACE));

Thanks a Lot,

I have a module in VC++6.0. it enumerates all desktop items and displays each item.tested this module on Win 2000 and Win XP.

After displaying each window i want to close each launched desktop item window by doing the following:
CWnd* pWnd = FindWindow(NULL, strName);//strName is name of window launched.
if(pWnd)
{ pWnd->PostMessage(WM_CLOSE,0,0);
}

but i get the foll error:
error C2065: 'CWnd' : undeclared identifier

i tried including the foll in the stdafx.h file
#define _WIN32_WINNT 0x0500
#include <windows.h>

still i get the same error.

What do i need to include to overcome this problem?
Kindly reply at the earliest.

Sincerely

ur project is a Win32 one which doesn't allow MFC.

go to "Project/Setting" to see if u can add MFC libraries into your project.

Check the "Ignore HTML tags in this message" otherwise the '<' and '>' will be considered as HTML tags and not displayed. An alternative is to use the tags that are just above the emoticons.

is it illegal to develop and distribute gaming (lotteries) programs on the Internet?

i guess it is illegal because I can not find this kind of software on the Internet.

The legal nature depends on a number of different factors:

(*) Content of the software.
(*) Software Components and/or libraries that go into this software, whose redistributable and/or similar licensing clauses do apply.
(*) Internet Bandwidth requirements and restrictions do apply.
(*) Particular country's/region's legal restrictions do apply.

You always send a buffer therefore the function first parameter is const void* lpBuf.

the trick is to know what you are sending and be able to read it on the other side.
so if you know you need to send a variable, translate it to the buffer (using simple Format of CString for example) and on the other side read the buffer and do a simple number translation (_ttol for example)

hope this helps ya

I have had the handle of the thread that belong to another process.
but I find that you can get few infomation from the handle.
Now,I want get Which module the thread belong to?
And I knew A software , ProcessExplorer http://www.sysinternals.com[^], can do this.

You ask "which module the thread belong to?". This question doesn't really make sense - A thread can "weave" through multiple modules (and in general does).

I didn't use your link.
I think u can numerate all processes, and enumerate all threads of every process to find the thread you request.

Looks like it’s the symbol for the thread entry point. I had a brief look but couldn't see any easy way to get this info - It didn't seem to be in any of the well known fields of the TIB for example. You could examine the bottom of the threads stack I guess.
