If you are prepared to change from MPEG format to AVI or WMV format, there is a lot more information on CodeProject. CodeProject does not have much on MPEGs, probably because the format is not supported directly by MS.
When I wanted to save an AVI file, this article http://www.codeproject.com/bitmap/createmovie.asp[^] was very useful.

I am using VC++6.0. iam in need of plotting graph using MFC.

I have to plot data vs time as and when the USB receives the data.

How do I do this as given in the article.
"Before the ActiveX control can be used in your application, it must be registered as a COM Component in the system registry. This is a self registering control. This means that to register the control in the system registry you only need to have an application load the control and call the control’s exported function DllRegisterServer. You can use the REGSVR32 utility or have your setup program do this."
Can you help me?

To register the OCX Control go to start>Run . Type regsvr32 in the edit box and put the path of the ocx where you have stored after that (in the edit box).
Press OK . You will get a confirmation that registration succeeded.
In the Visual Studio go to tools> Active X Test container. Select this and in the list that is populated with various activex controls registered on your machine you can find and test this one in the container. I hope you will be able to do this .

Am I suppose to store the ocx first? From where do I store it?

You need to download the ocx and save it on your machine somewhere. Then you will be able to register the ocx

hi there,
I tried doing the same.
ButWhen I click "OK" after slecting the path for the ocx, I get the error message as:
No DLL name specfied. Usage:...
I dont understand this. What dll name ?
|
|
|
|
|
At the top of the article click on download control binaries. This will pop up a dialog and ask for a path for where to save the .ocx file.
Now go to Start > Run type the path of the ocx and press ok. Now follow as my previous post

thanks very much. I could add it.
Will try working on it.
But a quick question....
i need to plot large number of points say,250,000 points in one attempt.
Will this control handle it? Or will it be slow after say 50,000 point or so...?

I haven't worked with the control much. But I hope that you will be able to use this control upto quite an extent.

I'm working on adding the hot-switching of languages to my app, though I have ran into a few problems. I have created sattelite dlls for each of the translated resources. I create a language selection menu at run time with the help of this[^]article. I am able to update the menu and progress bar but unable to update the main dialog. The dialog is contained within the language dlls and contains many controls (with text). So, after calling LoadLibrary how do you update the main window? BTW this is a non-MFC app.

Well, unless there is an easier method, I stored all the controls text into the string table and created a function to reset the text for each control

I have a MDI application. From CDoc, how can I get a handle on the
active document. I can do this for a SDI application:
<br />
CFrameWnd *pWndMain = (CFrameWnd *)AfxGetMainWnd();<br />
ASSERT(pWndMain != NULL);<br />
<br />
CDocument *pDoc = pWndMain->GetActiveDocument();<br />
ASSERT(pDoc);<br />
<br />
POSITION pos = pDoc->GetFirstViewPosition();<br />
<br />
CView *pView = pDoc->GetNextView(pos)<br />
How can I rewrite this code for an MDI? Please any response
any one can give me will be greatly appreciated.
Sincerely,
Danielle Brina (an overworked graduate student)

MDIGetActive() instead of GetActiveDocument should do it.

Any chance you can show me more code? I cant type:
CDocument *pDoc = pWndMain->MDIGetActive();
because MDIGetActive is not a member of CFrameWnd.
How would you rewrite that portion of code that I
posted earlier for an MDI?
Sincerely,
Danielle Brina

What's wrong with calling AfxGetMainWnd(), which is a global function, followed by GetActiveDocument()?
