Is there a simple way to test a DX9 driver in BMax

OK the examples won't compile in BMax 1.30. They fail on this line

wc.hInstance=GetModuleHandleA(0)

in the Create() function in DX9Graphics.bmx:

	Function Create:TD3D9Graphics( width:Int,height:Int,depth:Int,hertz:Int,flags:Int )
		Global _reg : Int
		If Not _reg : Int
			Local wc:WNDCLASS=New WNDCLASS
			wc.hInstance=GetModuleHandleA(0)
			wc.lpfnWndProc=WndProc
			wc.hCursor=LoadCursorA( Null,Byte Ptr IDC_ARROW )
			wc.lpszClassName=_DX9GRAPHICSEXWINDOWCLASS
			RegisterClassA( wc )
			_reg=True
		EndIf

		Local hinst:Int=GetModuleHandleA(0)
		Local title:Byte Ptr=AppTitle.ToCString()
	
		Local hwnd:Int
		If depth
			hwnd=CreateWindowExA( 0,_DX9GRAPHICSEXWINDOWCLASS,title,WS_VISIBLE|WS_POPUP,0,0,width,height,0,0,hinst,Null )
		Else
			Local style:Int=WS_VISIBLE|WS_CAPTION|WS_SYSMENU |WS_SIZEBOX 
			Local rect :TRect = TRect.Create(32,32,width+32,height+32)
			AdjustWindowRect Int Ptr Byte Ptr rect,style,0
			width=rect.Width()
			height=rect.Height()
			hwnd=CreateWindowExA( 0,_DX9GRAPHICSEXWINDOWCLASS,title,style,rect._Left,rect._Top,width,height,0,0,hinst,Null )
		EndIf

		MemFree title

		If Not hwnd Return Null

		Return New TD3D9Graphics._Create(hwnd ,width,height,depth,hertz,flags)
	End Function

with this error:

Compile Error: Unable to convert from 'Int' to 'Byte Ptr'

Does anyone know how to resolve this please? thanks.
