怎样在桌面上写字啊

[ddeng]

HDC dc = ::GetDC(0);
char *str = "text out to desktop.";
::TextOut(dc, 100, 100, str, strlen(str));
::ReleaseDC(0, dc);

[不解]

同一楼上的。

[yajunmao]

HAND hEnd = ::GetDesktopWindow();
CWnd *pWnd = CWnd::FromHandle(hEnd) ;
CDC *dc = pWnd->GetDC( );
dc->textOut(0,0"as");
pWnd->ReleaseDC();

[prog_st]

HDC dc = ::GetDC(0);
char *str = "text out to desktop.";
::TextOut(dc, 100, 100, str, strlen(str));
::ReleaseDC(0, dc);
可以写，但重画就没有了!
yajunmao(oldcat)的代码改正：
HWND hEnd = ::GetDesktopWindow();
CWnd *pWnd = CWnd::FromHandle(hEnd) ;
CDC *dc = pWnd->GetDC();
dc->TextOut(0,0,"as");
pWnd->ReleaseDC(dc);
写不出文字

[2ndboy]

HWND hWnd=FindWindow("Progman",NULL); //得到程序管理器窗口句柄
hWnd=GetWindow(hWnd,GW_CHILD); //得到SHELLDLL_DefView窗口句柄
hWnd=GetWindow(hWnd,GW_CHILD); //得到真正得桌面句柄
HDC hDC=GetDC(hWnd);
TextOut(hDC,0,0,"ABC",3);
ReleaseDC(hWnd,hDC);

能实现才怪，应该用 ::GetWindowDC(桌面窗体句柄)

[yajunmao]

::GetDesktopWindow();
