This is my code of osd show. But I don't know how to do.
Any one who can help me!


TOSDSurface osd; 

osd.dwSize = sizeof(osd); 

osd.dwHeight = 50; 

osd.dwWidth = 400; 

osd.dwTop = 1; 

osd.dwLeft = 1; 

osd.Transparency = 1; 

int hOSD = SendMessage(hwndDD, WM_MODULE_MSG, DDMODAPI_OSD_CREATE_SURFACE, (LPARAM)&osd);

 

HBITMAP bmSurface = (HBITMAP)SendMessage(hwndDD, WM_MODULE_MSG, DDMODAPI_OSD_GET_SURFACE_BITMAP, hOSD); // get bitmap

 

 SendMessage(hwndDD, WM_MODULE_MSG, DDMODAPI_OSD_SHOW_SURFACE, hOSD);

you need to get a compatible DC for HBITMAP bmSurface
and then draw on that with Windows GDI functions

I can't see the OSD text with the following codes!
I don't know what is wrong with the codes.

Code: Select all


CWnd   *pWnd   =   CWnd::FromHandle(hwndDD);



	 bmSurface = (HBITMAP)SendMessage(hwndDD, WM_MODULE_MSG, DDMODAPI_OSD_GET_SURFACE_BITMAP, surface_id); // get bitmap

	 WCHAR* m_sshow ;

	 m_sshow =  L"This is my text";



	 	HDC hdcTemp=::GetDC(NULL);

	  HDC m_hdcMemory =CreateCompatibleDC(hdcTemp);



	  SelectObject(m_hdcMemory,bmSurface);	

	Graphics g(m_hdcMemory);

	g.SetSmoothingMode(SmoothingModeAntiAlias);



POINT pt,pos;

	pt.x=0;

	pt.y=0;

	RECT rt;

	pWnd->GetWindowRect(&rt);

	pos.x = rt.left;

	pos.y = rt.top;

	SIZE SZ;

	SZ.cx=800;

	SZ.cy=80;

	BLENDFUNCTION b;

	b.AlphaFormat =AC_SRC_ALPHA;

	b.BlendFlags=0;

	b.BlendOp=AC_SRC_OVER;

	b.SourceConstantAlpha=255;	



	FontFamily font(L"å®‹ä½“");

	GraphicsPath path,path2;

	path.AddString(

		m_sshow,

		-1,              

		&font, 

		FontStyleRegular, 

		72, 

		Rect(5, 5, 500, 100),

		NULL);



	path2.AddString(

		m_sshow, 

		-1,              

		&font, 

		FontStyleRegular, 

		72, 

		Rect(8, 8, 500, 100),

		NULL);



	SolidBrush  byy(Color(128,0, 0, 0));



	LinearGradientBrush bin(PointF(0,0),PointF(0,80),Color(255,0,0,255),Color(255,0,255,0));;//å›¾å½¢å¡«å……ç”»åˆ·



	Pen pout(Color(128, 255, 255,255),1.0f);

	Pen pyy(Color(100, 0, 0,0),2.0f);









	g.FillPath(&byy,&path2);	

	g.DrawPath(&pyy, &path2);



	g.FillPath(&bin,&path);	

	g.DrawPath(&pout, &path);



	::UpdateLayeredWindow( hwndDD,pWnd->GetDC()->m_hDC,&pos,

		&SZ,m_hdcMemory,&pt,0,&b,2);



  SendMessage(hwndDD, WM_MODULE_MSG, DDMODAPI_OSD_REPAINT_SURFACE, surface_id);

 SendMessage(hwndDD, WM_MODULE_MSG, DDMODAPI_OSD_SHOW_SURFACE, surface_id);
