1. MFC program - background dialog color - stick in InitInstance
SetDialogBkColor( RGB(0,0,0), RGB(255,255,255) ) ; // background to black, text to white (black on black is not to readable :-))

2. Get Dimensions of a bitmap
BITMAP bm ;
GetObject( hBitmap, sizeof bm, bm ) ;
// where hBitmap = HBITMAP of the bitmap
// bm.bmWidth and bm.bmHeight hold the bitmap size

3. Get Dimensions of a control
CRect rect ;
pWnd->GetWindowRect( &rect ) ;
// pWnd = the control, if you're in a dialog try
//GetDlgItem( IDC_EDIT )->GetWindowRect( &rect ) ;

coords go into rect in screen units.  Typically you want them in client coords (relative to the window, you can convert to these using)
ScreenToClient( &rect ) ;

3. Playing sound waves - see next comment

Playing sound

1. To play a .WAV file

     PlaySound( "file.wav", NULL, SND_FILENAME ) ;
     or
     sndPlaySound( "file.wav", 0 ) ;

     for file name make sure you specify the full path.  If you use \ in string literals, then make sure you escape it
     e.g.
     "C:\\WINDOWS\\file.wav"  in C, means "C:\WINDOWS\file.wav" in DOS


     2. To play from resources

     i. Insert a .wav file into your resources
     - Go to resource tree on workspace
     - Right click
     - Pick "Import..."
     - Browse the WAV file
     - Assign an arbitary id, e.g. "IDC_WAVE"

     ii. Play the wave file with
     PlaySound( MAKEINTRESOURCE(IDC_WAVE),  AfxGetResourceHandle(), SND_RESOURCE ) ;


Make sure you #include <mm.h> (e.g. add this to stdafx.h) and link to winmm.lib (project settings)

Answers2000,
Solution 2 and 3 are OK. I have a few queries about solution number. Won't SetDialogBkColor change the background color of all dialog boxes in the application.
Thanks

Do you want the background of any particular dialog box of your app to be different?
