to avoid using up all your GDI memory, you should be able to convert each frame to a DIB fairly quickly (use GetDIBits), then delete the HBITMAP. the DIBs will live in non-GDI memory, so you won't hit the out of memory limit (well, maybe eventually, but it should be a lot larger than 145 frames).

I wanted to display a sequence of numbers in an Edit box just like a timer or a stop watch.Below is my code
void CEditDlg::OnButtonOK()
{ UpdateData();
for(double i=0;i<=25;i++){
m_d1=i; //m_d1 is the name of the variable of edit box
UpdateData(false);
Sleep(10);
}
}
the above code gives me an output of 25 whereas i want a sequence of numbers to be displayed b/w 0-25.how do i go abt it???

You can use GetDlgItem(IDC_OF_TEXTBOX)->SetWindowText(m_putStringHere); instead...

You have ket delay of 10 ms. Thats the reson, you are able to recognize last character displayed. Your code is setting text 0-25 to edit box. But, you are not able to see i, because it happens in very short time. May be, you can try setting dealy of 2 sec(2000ms).

No need to call UpdateData().
Change your for loop variable to an int, as a double makes no sense for what you are doing.
Change m_d1 from a CString to CEdit instead.
Update the edit control with m_d1.ReplaceSel() instead.
Using a different 'sleep' value is irrelevant.

Of course it does, since you are overwriting the contents of the edit control each time through the for loop.

In your for loop, you use the UpdataData (and that's OK), then sleep, but stay in the loop.
The UpdateData actually updates the data, and posts a message for the window to update, however, the message can't be processed until you leave this loop - that's why you only see the last number.
You can modify your code as follows to see each value. (and as noted, your loop control variable should be an int instead of a double).
void CEditDlg::OnButtonOK()
{ UpdateData();
for(int i=0;i<=25;i++){
m_d1=i;
UpdateData(false);
GetDlgItem(IDC_YOUR_EDIT_BOX_ID)->UpdateWindow();
Sleep(10);
}
}
Hope that helps.

IMediaSeeking is a COM interface. You can query the filter graph manager to obtain a pointer
to the interface (saves you the trouble of finding a certain pin to get the interface on!):
IMediaSeeking *pSeeking = 0;
hr = pGraphMgr->QueryInterface(IID_IMediaSeeking, reinterpret_cast<void**>(&pSeeking));
Note that not all filters support seeking. See Seeking the Filter Graph[^]

Actually I found out that I can not use seeking for the AVC decoder (by using GetCapabilities). So, I think maybe it is possible to use seeking directly to the demux filter. Is it possible?

Have you tried to obtain the IMediaSeeking interface from the filter?

I would be inclined to use:
void CMyClass::OnUnload()
{
CInternetSession m_Inet;
CFtpConnection* pConnection = NULL;
try
{
pConnection = m_Inet.GetFtpConnection(sServer, m_sUsername, m_sPassword));
...
}
catch (CInternetException e)
{
TCHAR szCause[255];
e.GetErrorMessage(szCause, sizeof(szCause));
AfxMessageBox(szCause, MB_ICONERROR);
}
if (pConnection != NULL)
pConnection->Close();
delete pConnection;
}

(Thanks for your answer.)
"CInternetSession m_Inet;" is declared as a class member but not initialized.
The "AfxMessageBox()" declared in the "catch" statement is not displayed.
The "GetFtpConnection()" function displays the following error messsage:
"220 NET+OS 6.3 FTP server ready"
"530 Not logged in"
and then it makes my function exit.
When I set some breakpoints with VS6, the debugger does not stop on them.
The end of my function is never reached!
Any more ideas, please?
Pascal
Thanks and regards

Which would seem problematic since you also have one declared in the OnUnload() method.

Submit an article or tip
(just get into DirectShow a couple weeks ago 
). It would be nice if you have the example, or any site that has it. I was looking at MSDN forum and found that we can put IMediaSeeking on the pin. What does it mean? How to do that?
