Subclassing ActiveX control

Alton Williams

I'm Creating an ActiveX subclassing "EDIT". I would like it to be able to change the colour of the background, text or indeed both. I've added the BackColor and ForeColor as Stock implementation. I've changed below:

BEGIN_PROPPAGEIDS(CEditTestCtrl, 1)
	PROPPAGEID(CEditTestPropPage::guid)
END_PROPPAGEIDS(CEditTestCtrl)

to

BEGIN_PROPPAGEIDS(CEditTestCtrl, 2)
	PROPPAGEID(CEditTestPropPage::guid)
	PROPPAGEID(CLSID_CColorPropPage)
END_PROPPAGEIDS(CEditTestCtrl)

I've also modified the OnDraw method to;

void CEditTestCtrl::OnDraw(
			CDC* pdc, const CRect& rcBounds, const CRect& rcInvalid)
{
	DoSuperclassPaint(pdc, rcBounds);
	//added
	pdc->FillRect(&rcBounds, &CBrush(TranslateColor(GetBackColor())));
}

The Bakground colour changes. The problem lies when enter text in the control, the control reverts back to the orignal colour. The question is what is the correct way in achieving this?:confused::confused: -- modified at 16:03 Tuesday 14th March, 2006

Hello Alton Williams, I don't have answer to your question but i just want to know why are you doing this through ActiveX control. I mean you can change the background and text color of standard Edit control by Handling WM_CTLCOLOR Message. Is ActiveX your requirement? Muhammad Azam

Use pdc->SetBkMode(TRANSPARENT) to make text background transparent.
