Re: Quick Question!

Thankyou guys for your inputs!

Also off the subject, I was just wondering if you guys ever ran into a
flickering problem!

If I may ask! Can you take a quick look at this code:
===========================================================
case WM_CREATE:
//Create brushes with particular default color
hBrush_hdMW_OtherControls = CreateSolidBrush(GetSysColor(COLOR_GRAYTEXT));
hBrush_hdMW_staticLab = CreateSolidBrush(GetSysColor(COLOR_BTNHIGHLIGHT));
hBrush_hdMW_staticIMV = CreateSolidBrush(RGB(100,100,100));

case WM_CTLCOLORSTATIC:
//Get the control ID
i = GetWindowLong((HWND)lParam,GWL_ID);

if (i >= 100 && i <= 105)
//Memory variable labels
{
SetTextColor((HDC)wParam,RGB(0,0,0));
 //Set the back color to the same color that is behind the control or
atleast I think it does????
SetBkColor((HDC)wParam,GetSysColor(COLOR_BTNHIGHLIGHT));

return (LRESULT) hBrush_hdMW_staticLab;
}

//Internal Memory variables
else if(i >=500 && i <= 505)
{
SetTextColor((HDC)wParam,RGB(0,0,0));
SetBkColor((HDC)wParam,RGB(255,255,0)); //Set the back color to particular
color

//Return the brush to color whole field of static control
return (LRESULT) hBrush_hdMW_staticIMV;
}
else
//The rest of the controls
{
SetTextColor((HDC)wParam,RGB(200,0,100));
SetBkColor((HDC)wParam,RGB(255,255,0));

return (LRESULT) hBrush_hdMW_OtherControls; //If I remove this line, these
controls don't get colored at all.
}

return 0; //break; //Also in the book example this line is a break. Isn't
it supposed to be a return? Just asking!

....other code.....

=================================================================

The code above causes flickering on the client area!

Do keep in mind that I am designing a real time system and therefore a
WM_TIMER event is executed every 150 milliseconds.!!!!! I don't know if this
has something to do with the flickering as, if I remove the code in the
WM_CTLCOLORSTATIC handler, the flickering goes away.

But also I seem to have some text control coloring difficulty. In some of
the controls, I would like that the full area of the background color of the
control to be fully collored(at times as default white or at other times to
a particular color). So to accomplish this, would I have to return the brush
as done so in the WM_CTLCOLORSTATIC handler.

Am I complicating things... wouldn't I just be able to set the text and
background colors for the controls *once* in WM_CREATE? If so, then would
the:

return (LRESULT) hBrush_hdMW_OtherControls;

line work in WM_CREATE? I don't think so. You see, I am looking at Colors1.c
from petzold's example and he needs constant repainting of the static text
controls and therefore I guess that's why he uses the WM_CTLCOLORSTATIC
handler. But I just need to do some innitial background and text coloring of
controls.

I did try to put the following code in WM_CREATE before the CreateWindow
commands, but the background color of the control defaults to a sort of
beige color, which is not what I wanted!

Also, the following code fragment makes sence in the WM_CTLCOLORSTATIC
handler, but not in WM_CREATE:
======================================================================
hBrush_hdMW_staticLab = CreateSolidBrush(GetSysColor(COLOR_BTNHIGHLIGHT));
SelectObject(hdc,hBrush_hdMW_staticLab);
SetTextColor((HDC)wParam,RGB(0,0,0));
//Set the back color to the same color that is behind the control
SetBkColor((HDC)wParam,RGB(255,255,255));
return (LRESULT) hBrush_hdMW_staticLab;
======================================================================

Basically to fully color the background of a control with a specific color
(not just color the backgroung behind the text of the control), do I have
the use of the following line:

return (LRESULT) hBrush_hdMW_OtherControls;

and the following handler with the WM_CTLCOLORSTATIC handler as shown at
the innitial code of this post?

Thanking you all in advance!

Regards!
