Hello,

How do you mean "transfer control to child thread"? Why do you want to do this? The OS does this for you repeatedly...

Huh? Maybe you meant passing the address of the current instance of your class to a function? Use the "this" keyword.

class A
{
   void Method()
   {
     Test(this);
   }
   void Test(A *a)
   {
   }
}

cout<<gc_add[i]->model<

Your function expects a pointer to a graphic_card.

neodeaths wrote:
grahpic_card gc[10];

You declare an array of graphic_cards.

neodeaths wrote:
add_new_item(&gc);

Your passing the address of an array, not a graphic_card.

Try this:
add_new_item( &( g[ 0 ] ) );
Now, this is passing the address of a single graphic_card.

What is the procedure to change the background of list box?

The best way is to override the WM_CTLCOLORLISTBOX[^] message.

You'll need something like HBRUSH m_hBrush = NULL; in your class definition and check you set it to NULL in your classes constructor. Once done, override the DefWindowProc for your controls parent window and add to it...

switch( message )
{
	case WM_CTLCOLORLISTBOX:
	{
		if( m_hBrush == NULL )
		{ // Fist time we're called so create the brush
			LOGBRUSH lb;
			ZeroMemory( & lb, sizeof( LOGBRUSH ) );
			lb.lbStyle = BS_SOLID;
			lb.lbColor = RGB( 0, 0, 255 );
			m_hBrush = CreateBrushIndirect( & lb );
		}
	
		SetBkColor( ( HDC ) wParam, RGB( 0, 0, 255 ) ); // Text background to Blue
		SetTextColor( ( HDC ) wParam, RGB( 255, 255, 255 ) ); // Text color to white
	
		return ( LRESULT ) m_hBrush;
	}; break;
}

Obviously when the window / class is destroyed you'll need to destroy the brush you've alllocated so add something like if( m_hBrush != NULL ) DestroyObject( m_hBrush ); aswell.

This will currently set every list box on your window to the colour Blue, if you want to be more selective all you need to do is compare the list boxes handle to the lParam of the WM_CTLCOLORLISTBOX message.

I dont know if there is a option to enable or diable that setting but you can do that manually.
In the project settings, under the link tab, There is a edit box called as Project Options, in that box add /NOENTRY with the other options similarly you add any other linker options.
