CButton surrounded with a red line

[Drakesal]

Hi all

i am trying to do a button with red line around it, i don't know exactly how do it.

i am understanding i need to take the DC with GetDC and i have to use a pen,
but i cannot see any red line.
Can somebody show me how do it?

Thanks in advance.

You have to use an ownerdraw button. Search MSDN for details.
Besides there is a lot of examples in CD and CP article sections.

Well, I would go with painting in dialog's DC. That would allow me to have not only ownerdrawn buttons there in the dialog.

i am trying in this moment like this:

void CFormView::OnDraw(CDC* pDC)
{
CPen NewPen;
CRect r;

GetDlgItem(IDC_BUTTON)->GetClientRect(r);

NewPen.CreatePen(PS_SOLID, 1, RGB(255, 25, 5));

pDC->SelectObject(&NewPen);

pDC->Rectangle(r);
}

But the rectangle is drawn the same dimension but is not centered on the button, maybe i am near please help me to understand this

GetClientRect gives you coordinates of control's client area. What you need is control's window rect mapped to dialog's client area. Besides, you need to inflate the rect a little to let the line be not obscured by the control borders.

As Igor said, you need to make the rect bigger than the button of the button will draw right over the top of it.

I've done it!!!!

I post this for future reference:

void CFormView::OnDraw(CDC* pDC)
{
CPen cpRedPen;
CRect crRect;

cpRedPen.CreatePen(PS_SOLID, 5, RGB(255, 0, 0));

pDC->SelectObject(&cpRedPen);

m_MyButton.GetWindowRect(crRect);

ScreenToClient(crRect);

pDC->Rectangle(crRect);
}

You need to get to a habit of unselecting everything you selected, after your drawing completed.
