You can download FFMPEG from http://ffmpeg.mplayerhq.hu/download.html[^]. It can be built using MINGW and MinSys
Instructions here
http://soenkerohde.com/tutorials/ffmpeg/

Or you can directly download a pre-built version of FFMPEG that has the dlls and the exe ready. The dll also has a def file but that's hardly helped since it mentions what functions are there but not the paramters Frown | :-(

Device context trouble

I am stuck in device context trouble.
Right now I am conclusion it will be worth to get directly
desktop dc for generic class.
If any body can suggest me way for passing device context to generic class
through thread function or getting desktop dc directly for drawing in generic class.

Here simulate is generic class and the nextpos function is doing lot of drawing stuff.and it needs device context,I have developed SDI application.
and used CView as base.

UINT CMy5CYLINDERView::ThreadFunc(LPVOID pParam)
{
CWnd *cwnd,*cwnd1;
cwnd1 = cwnd->GetWindow(1);
CDC* pDC = cwnd1->GetDC();
simulate* eng = (simulate*)pParam;
eng->nextpos(pDC);
// eng->nextpos(pszWindow);
return 0;

}

void CMy5CYLINDERView::support()
{
for(int ii = 0;ii <= 3;ii++)
{
x[ii] = AfxBeginThread(ThreadFunc,(LPVOID)&engine[ii]);

}
}.

I tried solutions you given that day but it didnot worked.
How to get the window

CDC* pDC;// = this->GetDC();
HWND hwnd = ::GetActiveWindow();
HDC hdc = ::GetDC(hwnd);
pDC->SetOutputDC(hdc);
nextpos(pDC);

just now I tried longest path it also didnot worked.
I removed thread still I am able to get and pass the dc.
moment I assign anything to pDC it gives error

CDC* pDC without value so you get one error pDC=GetDC();
this line has error pDC->SetOutputDC(hdc);

Thanks friend i got my error.
I was calling this support fuction from the constructor before creation of window.
so it was unable to get the device context.now at least I got the dc.
now i am calling it though onlbuttondoubleclick.

As code for support I written much below the file inwhich I was saying this->getdc(),but the this pointer was not of the window.

Closing a invisible web browser

KongHL1-Jun-06 19:47

Hi,

Is there a way to close an invisible web browser? how do i detect the web browser and close it??

Thanks!!

You have to do COM Programming. Interface of Internet Explorer com object is IWebBrowser2. You have to get the invisile instance of IE by calling CoGetObject() COM API. Then you can call it's interface methods to close the Invisible Browser.

Once you get the COM instance of API. Then call the COM method ExecWB of IWebBrowser2 with parameter OLECMDID_CLOSE. Then the invisible browser will be closed.

OK ?

The problem is i created the browser in a dll (in a thread).. when i tried to terminate the thread, the browser is not closed via the quit() function.
Hence I am trying to close in in the main program.. but this way, i dun have the instance of it.. I need to find it and close it right?

Why Not have that Variable of Webbrowser as Class member and pass the current instance of class object to thread, and using that Variable so that you can manipulate the browser from teh Main program..
don't forget to add CoInitialize(NULL)

1) Create your MFC application project.
2) Download SDL runtime library (SDL.DLL) from HERE[^].
3) Copy SDL.DLL into your project folder.
4) Read those documents at SDL website, such as THIS[^] and THIS[^] ...
