transparent static text on bitmap background problem

hi,
on the function OnCtlColor
i am doing the following in order to draw background bitmap.
{
HBRUSH hbr;

hbr=CDialog::OnCtlColor(pDC,pWnd,nCtlColor);

static HBRUSH hBrush=NULL;
if(nCtlColor == CTLCOLOR_DLG)
{
CBitmap bitmap;
bitmap.LoadBitmap(IDB_BACK);
if(!hBrush)
hBrush=CreatePatternBrushbitmap);
hbr=hBrush;
}
return hbr;
}

i want to show the static text i got on this dialog with the transparent style but what i get is the gray background.
i checked the transparent box in the properties.
some1 maybe got a solution?
thanks.

Is the rest of the dialog background correct?

If you want to modify the background color for the static control itself, you must change your IF statement so that CTLCOLOR_STATIC is also handled.

You may also need to handle OnEraseBkgnd().

Derive a class from CStatic
handle WM_ERASEBACKGROUND. In thie OnEraseBackground function draw the bitmap u want.

If u want to draw the image of the dialog, just set that bitmap to this class. This class wants to keep a memory dc of this bitmap, and draw it on OnErasebackground.

There is no need to draw the static text on the control. That all will done by the parent class

GOOD LUCK

thank you both for your answers but i still can't get it.

DanRollins: i did what u said but now only the checkboxes i am using have transparent labels but all the edit boxes and static text controls still with gray background
(btw the transparent background the checkboxes has now is not "smooth" with the background)

roshmon: i am trying to understand your point, the problem i got is that the static text i am using are created by the resource editor and not dynamically.
i am also having problem to understand it correctly i think.

thanks both an di hope u can help me more.

best way is open the bitmap in paintbrush and edit it.
then save it

it'll work
