Placing A Bitmap In The PropertySheet Button Area

<p>I was recently asked to write an application for a company
that wanted their logo on every single window in the program. As
the application grew there became less and less space for a
company bitmap logo within some of the tabbed-dialog boxes. Due
to this I decided to see if I could place the bitmap logo in the
PropertySheet area that is normally only used by the the OK,
Cancel and <u>A</u>pply buttons. The picture below shows what I
achived...</p>

<p>To do this is quite easy.</p>

<p><strong>1. </strong>Firstly create a subclass of
CPropertySheet called CMyPropertySheet.</p>

<p><strong>2. </strong>Override the WM_PAINT message by creating
an OnPaint() member function for CMyPropertySheet, and paste the
follwing code into it.</p>

<PRE><TT><FONT COLOR="#990000">
CBitmap bmp, *poldbmp;
CDC memdc;
CRect rect;
	
//Load the bitmap resource 
bmp.LoadBitmap(IDB_BITMAPLOGO); 

//Create a compatible memory DC
memdc.CreateCompatibleDC(&amp;dc);

//Select the bitmap into the DC
poldbmp = memdc.SelectObject(&amp;bmp);//bmp

//Get size of PropertySheet
GetClientRect(&amp;rect);

//Copy (BitBlt) bitmap from memory DC to screen DC
dc.BitBlt(left, rect.bottom - lower, w, h, &amp;memdc, 0, 0, SRCCOPY);

memdc.SelectObject(poldbmp);</tt></font></pre>
</FONT></TT></PRE>

<p>The dc.BitBlt places a <em>w</em> pixel wide by
<em>h</em> pixel high image <em>left</em> pixels away from the
left hand edge, and <em>lower</em> pixels away from the bottom of
the PropertySheet. Change these values as you see fit.</p>

<p><strong>3.</strong> <em>#include &quot;MyPropertSheet.h&quot;</em>
in the calling dialog that you wish to use the new property page
in.</p>

<p><strong>4.</strong> Add PropertyPages to the PropertySheet and
call it, e.g.....</p>

<PRE><TT><FONT COLOR="#990000">
    CMyPropertySheet sheet(&quot;Personnel Details&quot;);<br>
    CPerFildlg perfildlgPage;<br>
    CAddDetdlg adddetdlgPage;<br>
    CDelDetdlg deldetdlgPage;<br>
    <br>
    sheet.AddPage(&amp;perfildlgPage);<br>
    sheet.AddPage(&amp;adddetdlgPage);<br>
    sheet.AddPage(&amp;deldetdlgPage);<br>
    <br>
    sheet.DoModal();
</FONT></TT></PRE>

<p>More advanced code for drawing bitmaps / DIBs which also uses
palettes may be found on this site.</p>
