Change TextBox Color on FOCUS and ENDFOCUS

[Borje Hagsten]

Use GetFocus in your %WM_CTLCOLOR.. handler, like in PB's SMTP sample:

    CASE %WM_CTLCOLOREDIT
      IF CBLPARAM = GetFocus THEN
        SetTextColor CBWPARAM, %BLACK
        SetBkColor CBWPARAM, %WHITE
        FUNCTION = GetStockObject(%WHITE_BRUSH)
      ELSE
        SetTextColor CBWPARAM, %BLUE
        SetBkColor CBWPARAM, %LTGRAY 'RGB(255, 255, 196) '%LTGRAY
        FUNCTION = GetStockObject(%LTGRAY_BRUSH)  '%LTGRAY_BRUSH
      END IF

Note: to be placed in Main dialog's callback procedure..

I have 7 TEXTBoxes and I'm subclassing all of then via:

SetWindowLong(GetDlgItem(hDlg&, %hDLG_TEXT1), %GWL_WNDPROC, CodePtr(CB_SUB_TEXT1)
etc etc

I'm destroying them at %WM_DESTROY in DlgProc

I can successfully trap %EN_SETFOCUS at the DlgProc level but
not at the subclassed level, I'm wanting to be able to change
the color of a textbox when it received focus to:

    SetTextColor Cbwparam, %Red
    SetBkColor Cbwparam, %Yellow

and when it looses focus:

SetTextColor Cbwparam, %Black
SetBkColor Cbwparam, %White

I know I will need to create my two brushes %white and %yellow
and destroy them at %%WM_DESTROY

Any suggestions? Do I have to do the color changing within
DlgProc or can I do it in its Own SubClassed Callback?

I can even get %EN_SETFOCUS notification on my SubClassed
callback, but I do receive it via DlgProc, and use Cbctl to
receive the control.

Thanks
