static CMy5CYLINDERView::pszWindow = NULL; // initialize it globally
on Initial update, update this value with this pointer. then u can access it at the thread function
CMy5CYLINDERView::pszWindow->GetDC();
there is one more option.
define a structure that contains all information u need at thread
the definition may goes like this
This highlighted line gives error as pszwindow is not object of CDC
its really problem beacause this thread function is static and it restricts a lot

You are using cwnd but it was never initialized....
The DC of which window do you want to get?
Is eng is part of that window?
If so , try using this code:
UINT CMy5CYLINDERView::ThreadFunc(LPVOID pParam)
{
YourWindow *wnd = (YourWindow *)pParam;
CDC* pDC = wnd->GetDC();
wnd->eng->nextpos(pDC);
return 0;
}
With best regards,
Eli

YourWindow *wnd = (YourWindow *)pParam;// You should pass the handle of the window as pParam
Here what means YourWindow
Beacuse I am able to get the active window I am not able to get device context.
will you please explain me what you mean by your window.
I tried long journey of HWND hwnd = :: GetActiveWindow()
then CDC tempdc = (CDC*)( ::GetWindowDC(hwnd));
but it also proved hopeless.

A CWnd based class creates a popup window:
BOOL b=CreateEx(0,0,0,WS_POPUP|CHILD,rc,pMum,100);
in XP, the call failed, by in 98 and other OS, the call is OK.
how to solve the problem for XP?

Can you be more specific do you get error

BOOL o=CWnd::CreateEx(0, AfxRegisterWndClass(0), "CTest1", WS_POPUP, 0,0,0,0, NULL, 0);//return 1

WS_POPUP and WS_CHILD flags do not go together. Only pass WS_POPUP with valid parent window handle.

You have to Enumerate all window on desktop and compare each Processs handle to that Enumerated Window Process Handle!

How about GetWindowThreadProcessId()?

Use the following code
BOOL CALLBACK EnumWindowsProc(HWND hWnd, LPARAM lParam)<br />
{<br />
EnumInfo info;<br />
DWORD pid;<br />
EnumWin * enumWin =<br />
reinterpret_cast(lParam);<br />
GetWindowThreadProcessId(hWnd, &pid);<br />
<br />
if (pid == enumWin->m_pid)<br />
{<br />
if(GetParent( hWnd ) == 0)<br />
{<br />
enumWin->m_found = TRUE;<br />
enumWin->m_hwnd = hWnd;<br />
AfxMessageBox("handle found!");<br />
return FALSE; <br />
}<br />
}<br />
return TRUE;
}
you can use WaitForInputIdle(...) for the process to finish initializing before you try to find its HWND. this will not work with apps that start with a process and switch to another while excuting (e.g. mozilla fire fox).

I have an issue that requires either the rotation of the application (MFC Doc/View architecture - yes i know but it's a legacy application) or the screen (ATI Radeon). I've tried using the ChangeDisplaySettings API call (it does this already to set the required resolution, and yes I know this is a bad thing generally but this project requires the switching of two legacy applications both of which are EPoS and the operator is trained and paid to put up with it) and setting the rotation flag to DM_180 but I always get a DISP_CHANGE_BADMODE.
So I have a display on a hinge, and one application (the doc/view one) ends up being upside down. The ATI card has a tray application which lets the display be flipped, but I can't how to do it using API calls, or even calling into an ATI dll. (The ATI card isn't guaranteed to be used throughout the life of the project, it could well be replaced by another make/model). Unless some clever person out there can tell me how to rotate the display programically, the only other way is to add some code so that the output of the doc/view application is inverted.
Does anyone have any ideas?

No idea if that works, but you can try SetWorldTransform in the OnPaint event of your view, maybe in the frames.

Thanks, I gave that a go just now on one of the dialogs and managed to rotate the background but none of the controls on the dialog. I suspect I would have to override the onpaint events for absolutely everything, which for a new application could be a fun flag for the registry but for a crusty old legacy app it's not happening.
