changing color of a pushbutton on a dialog box
 

Hi,

I want to change the color of my button during runtime..

i am writing the following code inthe OnCtlColor of my dialog box

HBRUSH CPIVSyncDlg::OnCtlColor(CDC *pdc,CWnd *pwnd,UINT nCtlColor)

{

        HBRUSH hbr = CDialog::OnCtlColor(pdc,pwnd,nCtlColor);



        switch(nCtlColor)

        {

                case CTLCOLOR_BTN:

                        if(pwnd->GetDlgCtrlID() == IDC_STARTSTOP)

                                pdc->SetBkColor(RGB(255,0,0));

                        return (HBRUSH)m_btbrush.GetSafeHandle();

                case CTLCOLOR_DLG:

                        pdc->SetBkColor(RGB(255,255,255));

                        pdc->SetBkMode(TRANSPARENT);

                        return (HBRUSH)m_hbrush.GetSafeHandle();

                case CTLCOLOR_EDIT:

                        pdc->SetBkColor(RGB(0,0,0));

                        pdc->SetBkMode(TRANSPARENT);

                        return (HBRUSH)m_hbrush.GetSafeHandle();

                default:

                        return CDialog::OnCtlColor(pdc,pwnd,nCtlColor);                

        }

        return hbr;

        //return (HBRUSH)m_hbrush.GetSafeHandle();

}

the button is IDC_STARTSTOP i want to turn it red..but the interesting thing is the whole dialog box turns red except the buttons...

i have searched the msdn library and I am following all the instruction given in example ...all in vein... any suggestion would be helpful..

thanks,
Hardik

Re: changing color of a pushbutton on a dialog box
 

the method in "How do I change the background color of a control?" will not work for buttons!

If you want to change the color of a dialog button, you have to use an owner-draw button. (You can use bitmap buttons.) Changing the color through OnCtlColor() will not work for buttons. The following Knowledge Base articles may be of help to you: Q32685, "Using the WM_CTLCOLOR Message,"

What is here m_btbrush and m_hbrush ?

I got an error with this code like this :

error C2228: left of '.GetSafeHandle' must have class/struct/union
