Are you spawning the .exe? If so, you should squirrel away the handle for when you are trying to close it.
Considering that it is always possible to have more than one process with the same name running, it's really a crap shoot anyway without a handle.

If you have the process ID, then you could use EnumWindows() to search through all top level
windows and for each window found, use GetWindowThreadProcessId() to look for a matching
process ID.

Hello all,
I've tried to use the OnCtrlColor handler and return a different brush in order to change the background color, and also a different pen in order to change the text color, but none of them work with the checkboxes...
How should I do it in order to be able to change the text color?
As always thank you in advance.

Call SetTextColor() and SetBkColor() on the DC passed into OnCtlColor

I was doing this and it did not worked for me...
HBRUSH CTAM_BODlgPaletStats::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);
if (GetFocus() == pWnd)
{
pDC->SetTextColor(RGB(255,0,0));
pDC->SetBkColor(RGB(0,255,0));
}
return hbr;
}
I've been trying to use those two functions, and they work fine for ll the editboxes and static controls in my dialog, but not for my checkboxes...
Any idea?

My bad.
A checkbox is a button, so it does not respond to WM_CTLCOLOR. You have to use the BS_OWNERDRAW style and do all the drawing yourself in response to a WM_DRAWITEM message.

ah.. that was it...
I knew that the checkbox was a button but then...
in the MSDN help:
nCtlColor (->one of the parametes of the OnCtlColor)
Contains one of the following values, specifying the type of control:
<code>CTLCOLOR_BTN Button control</code>
CTLCOLOR_DLG Dialog box
CTLCOLOR_EDIT Edit control
CTLCOLOR_LISTBOX List-box control
CTLCOLOR_MSGBOX Message box
CTLCOLOR_SCROLLBAR Scroll-bar control
CTLCOLOR_STATIC Static control
well, who knows...

I forgot to thank you for your feedback! 
I'm searching for an alternative solution, so don't worry on that, I think is strange but...

Yes, I did not remember that class, some time ago I played a little with the CButtonST from Davide Calabro, it worked great, but I wanted to stick to "standard material", but I'll consider that, it worked really well some time ago.
Thank you for your feedback!

When I use this class to draw a picture in a timer function.
I find my free memory lose too fast!!
Who can help me !!
Thanks!!!
(My english is not very well!)
class CCarton
{
public:
CCarton();
virtual ~CCarton();
void Init( CWnd* pWnd );
void Draw( CDC* pDC, INT iX, INT iY );
private:
CBitmap m_bmp;
CBitmap *m_pOldBmp;
CWnd* m_pDrawWnd;
CDC m_dcSrc;
BITMAP bm;
};
CCarton::CCarton()
{
m_pOldBmp = NULL;
}
CCarton::~CCarton()
{
if( m_pOldBmp != NULL )
{
m_dcSrc.SelectObject( m_pOldBmp );
m_dcSrc.DeleteDC();
}
}
void CCarton::Init( CWnd* pWnd )
{
m_pDrawWnd = pWnd;
m_bmp.LoadBitmap( IDB_BITMAP );
m_bmp.GetBitmap( & bm );
CDC* pDC = pWnd->GetDC();
m_dcSrc.CreateCompatibleDC( pDC );
m_dcSrc.SetBkMode( TRANSPARENT );
m_pOldBmp = m_dcSrc.SelectObject( &m_bmp );
}
void CCarton::Draw( CDC* pDC, INT iX = 0, INT iY = 0 )
{
pDC->BitBlt( iX, iY ,bm.bmWidth, bm.bmHeight, &m_dcSrc, 0, 0, SRCCOPY );
}
// use draw at here !
void CBmpView::OnTimer(UINT nIDEvent)
{
m_Carton.Draw( GetDC(), 0, 0 );
CView::OnTimer(nIDEvent);
}
//initializing at here
void CBmpView::OnInitialUpdate()
{

Thank you for you help !
I know it now.
Every times after use DC do someting must release it to free memory!
Thank you again!

hi!
i want to get color of the pixel, but my system sets 16 bits for color quality. what function do i call instead of calling GetPixel?
is there a sample?
thank you

No matter, the same. It returns a COLORREF value which is simply an integer value containing the values for rgb [and alpha if applied].

if the system sets 32 bits for color quality, the GetPixel function returns a DWORD valu. but what type of value does this function return, if the system sets 16 bits for color quality? a DWORD?
Zo.Naderi-Iran

Yes DWORD and always DWORD (actually it is typedefed as COLORREF). Only the but organization is different in different bpp modes. Usually in 16 bpp it is 555 or 565 (5 bit for blue, 5(6) bit for green and 5 bit for red). Also not that res bits are leftmost [and thus blues are rightmost].

ah sorry; red bits are rightmost and blue bits are leftmost

Actually, GetPixel() returns a COLORREF which has 8 bits per colour no matter what the DC's colour depth is. You only have to worry about the bit structure when you directly access the bitmap data as in a DIB or DIBSection.

I have to access a control from one dialog box of one class to another class.
I tied this but I an getting runtime error.

Each dialog is responsible for its controls and if somewhat you need to access a control that belongs to another dialog box, then there is problems with your design. So try to change the design. Also try to be more specific when asking questions it will help readers to better concentrate on the real issue.

Is this code helpful
CMain* m_Main=(CMain*)GetParent();
m_Main->ControlsOnOtherClass
