Please stop doing this. Do not just dump a load of code with a vague comment and expect someone to figure out what the problem is and then fix it for you. Edit your question, remove the code not relevant to the problem, and explain clearly what is going wrong, and where it happens.

The _T() macro is for constant strings (and characters) only:

// Wrong:
//bmp = LoadBitmap( hinstance , _T( file ) ) ;
// Correct:
bmp = LoadBitmap(hinstance, file);

When supporting Unicode and non-Unicode builds, all constant strings must be embedded in that macro:

// Wrong:
//player.loadbmpfromfile(hThisInstance,"player.bmp") ;
// Correct:
player.loadbmpfromfile(hThisInstance, _T("player.bmp"));

Both errors look like they could be coming from the call to LoadBitmap(), but since you failed to include line numbers, it's hard to say for sure. That function returns a BOOL not a BITMAP. Also, the _T() macro is for string literals.

a error font by the compler can have a source elsewere so i have to post al the code i don't know how to include the line numbers my english in writing is not great so i have to be short

ok i try it i changed the folowing : player.loadbmpformfil( ,_T("player.bmp)) ; my sprite looks like this now :

class Sprite
{
public :
int x , y , w , h ;
bool visable ;
HBITMAP hbmp ;
HDC bmphdc ;
Sprite(){;}
void loadbmpfromfile( HINSTANCE hinstance , TCHAR * file )
{
hbmp = LoadBitmap( hinstance , file ) ;
w = hbmp.i ;
h = hbmp.i ;
visable = true ;
}
void show( HDC hdc )
{
if ( visable )
{
//draw mask whit and [ upper half of bmp ]
BitBlt( hdc , x , y , w , h/2 , bmphdc , 0 , 0 , MERGECOPY ) ;
//draw picture whit or [ lower half of bmp ]
BitBlt( hdc , x , y , w , h/2 , bmphdc , 0 , h/2 , MERGEPAINT ) ;
}
}
bool hit( Sprite spr )
{
if ( x + w < spr.x ) return false ;
if ( x > spr.x + spr.w ) return false ;
if ( y + h < spr.y ) return false ;
if ( y > spr.y + spr.h ) return false ;
return true ;
}
} ;
Sprite player ;

i know this is wrong . how do i do this ? my wm_paint :

case WM\_PAINT :
  GetClientRect( hwnd , &rect ) ;
  winx = rect.right ;
  winy = rect.bottom ;

  player.bmphdc = CreateCompatibleDC(hdc);

  player.show( hdc ) ;

  DeleteDC( player.bmphdc ) ;

  EndPaint( hwnd , &paint ) ;

this can be wrong . how do i do this ?

I told you a week ago, you must call BeginPaint inside your WM_PAINT code. So it needs to be:

case WM\_PAINT :
  hdc = BeginPaint( hwnd , &paint );

// All painting code or calls to functions that paint:

  EndPaint( hwnd , &paint ) ;
  break; // make sure you have a break or return after every case block

ok done that how do i proseed next ?

case WM\_PAINT :
  hdc = BeginPaint( hwnd , &paint ) ;
  GetClientRect( hwnd , &rect ) ;
  winx = rect.right ;
  winy = rect.bottom ;

  player.bmphdc = CreateCompatibleDC( hdc ) ;

  player.show( hdc ) ;

  DeleteDC( player.bmphdc ) ;

  EndPaint( hwnd , &paint ) ;
  break ;
case WM\_DESTROY :

What errors? Where do they occur? What is your code trying to do? Please provide proper information so we can try to help. Also, if this is all new to you then you would do well to study some tutorials on Windows programming. Here are two that are very useful: EFNet #Winprog[^] Win32 Programming - FunctionX[^]
