background color in a edit ctrl

[wduty]

I'm trying to change the background color in a edit control. The help files say catch the WM_CTLCOLOREDIT message which gives you the HWND in the lParam and HDC in the wParam. The message call appears to be right. However, neither SetBkColor or SetTextColor work in this context.


case WM_CTLCOLOREDIT:
[tab]SetBkColor((HDC)wParam, RGB(0,0,0)); // doesn't work
[tab]GetClientRect(ghEdit, &cr);
[tab]FillRect((HDC)wParam, &cr, CreateSolidBrush(RGB(255,66,00)));// works but only proves the hdc is valid
[tab]break;

I had earlier faced similar problems here is the way by which I resolved it.
Depending on Value of m_nErrorColor I change the Background color of My Edit box for showing Warnings and Error
and here m_ErrorEditCtrl is my Edit Ctrl for showing errors. I change the back gournd of Edit Box in OnCtlColor function. GREYBRUSH,REDBRUSH,YELLOW BRUSH are defined RGB values for different colors.

HBRUSH CActiveChildDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
HBRUSH hbr = IOrderEntryDlg::OnCtlColor(pDC, pWnd, nCtlColor);
// TODO: Change any attributes of the DC here

if (nCtlColor == CTLCOLOR_STATIC||nCtlColor == CTLCOLOR_EDIT)
{
if(pWnd && m_ErrorEditCtrl)
{
if (pWnd->m_hWnd == m_ErrorEditCtrl).m_hWnd )
{
switch(m_nErrorColor)
{
case 1:
pDC->SetBkColor(REDCOLOR);
break;
case 3:
pDC->SetBkColor(YELLOWCOLOR);
break;
default:

pDC->SelectStockObject(GRAY_BRUSH);
}
}
}
}

// TODO: Return a different brush if the default is not desired
return hbr;
}
