VC6's template support was not complete, especially when dealing with complex classes like your example. Sometimes, you just have to say it ain't gonna work in 6.
BTW, "dtor" is the abbreviation for "destructor" (along with "ctor" for "constructor")

How to get device context from the runtime class used in multithreading application. For the application I am using single document interface.
Is there any easy way to get device context whenever and whereever you want?
The way of Creating device context with CreateDC seems to be worse than creating
another application. Where to get driver file name which drivers are installed by windows automatically.

A CDC* is passed to the view's OnDraw() method. The view's OnPaint() method creates a local CDC-derived object. Where else are you needing it?

In multithreading application we do pass RUNTIME CLASS.
In that runtime class we write the all the stuff which the thread is suppose to do.
Now my thread is going to draw something on document. My question is how to
achieve device context for the same purpose, and where to achieve
Moreover my application is crashing as I am not getting device context at the point
where I start using device context

How? The document is not something that can be drawn on. You can only draw on CWnd-derived objects (e.g., CView).

Friend sorry Its Single document interface application,CView is there.

Of course. It stands to reason that if you have a document, you will also have a view. What makes no sense is that you wanted to draw on the document.

Actually I dint get your question.
It is possible to get device context by passing Window handle to ::GetDC function.

I tried all the stuff but how to get handle of SDI window from the class instance which is used inside runtimeclass which is being called by SDI using
AfxBeginThread
void CMy5CYLINDERView::support()
{
for(int ii = 0;ii < 1;ii++)
{
x[ii] = AfxBeginThread(RUNTIME_CLASS(SHIV)); //SHIV is my RunTime class.
}
}
//FOllowing is constructor which is using another simulate class instance engine.
SHIV::SHIV()
{
engine.getdata(0);
engine.nextpos();
}
//And this nextpos method requires DC to draw
void simulate::nextpos()
{
CWnd* cc;
cc = (CWnd*)GetWindow(();
CDC* pDC = cc->GetDC();
CBrush bluebrush,old,white;
white.CreateSolidBrush(RGB(200,

which windows DC you want? MainFrame? Try AfxGetMainWnd() instead of GetWindow

This is something you can check with Spy++, but i'll expect at least something like WM_CLOSE or/and WM_DESTROY or/and WM_NOTIFY.

plz tell me how can i made animated a text or picture on a dialog box

Use GetDC() to get the DC of the dialog and use that to draw on the dialog.
TextOut to output the text.
Somethings seem HARD to do, until we know how to do them.

You should use the function GetDC() whenever you want to draw something and ReleaseDC() ASAP.It's not suggested to hold on to a device context for long.

No need to shout.
GetDC() returns a device context ( a CDC object ), which has plenty of member functions you can use to draw text or anthing. Search for CDC in the MSDN toget some infos about hte possibilities you have.

Create the DC where you need to draw.
You can use ::GetDC(HWND) if you have the handle to a window.

This should give you a general idea.
For an animated picture, can you use an animated GIF file?
