Status Bar

Problem 1.
I have derived my own class from CStatusBar. I want
to erase the statusbar background and give my own
colour. So I have provided implementation for 
OnEraseBkgnd() as follows:

afx_msg BOOL CWdStatusBar::OnEraseBkgnd( CDC* pDC )
{
CBrush hBrush;
hBrush.CreateSolidBrush( RGB(255, 255, 0));
CRect rect;
GetClientRect(rect);
pDC->FillRect(&rect, &hBrush);
return TRUE;
}

But this code only changes the colour of the statusbar
border.  I donot want to override OnPaint() because then
I have to take care of a lot of other details like 
drawing the panes for the statusbar.
Any suggestions?

Problem 2.
The status bar is displayed with a sizing grip. I would
like to remove the sizing grip. Actually I don't 
want the status bar to be resized. I tried changing 
styles in the Create() of status bar but it does not 
help.
Any Suggestions?

This is the first time, in my 6 months of membership with the mfc-l mail 
list, that I am seeing a question slipping in WITHOUT the environment 
line heading it.

Unless the environment is specified, it is impossible to post a concrete 
answer.  

Mihir.

The bar gets a size grip because the window you've put it into
is resizeable.  The size grip is the windows standard UI to show
that the window is resizeable.  The code that does this is right
there in MFC; trace into CStatusBar::Create() and you'll find:

	if (pParentWnd->GetStyle() & WS_THICKFRAME)
		dwStyle |= SBARS_SIZEGRIP;

Since you say that you've already derived your own class for
your style bar, you should be able to override PreCreateWindow()
and filter out the SBARS_SIZEGRIP style. 

On the other hand, I'm not sure I understand how you expect the
status bar to not be resizable without making the parent window
not resizable.  If you don't want the status bar to be resized,
you should make the parent window not resizable--that'll remove
the sizegrip _and_ make the status bar not resizable.
