Once you have opened your file:
long size;
fseek(file,0,SEEK_END);
size = ftell(file);
rewind(file);

Hi,
In my application I created a wmv movie form 3 images. It also have the audio for 15 seconds. Audio per frame is variable means that we can have audiofor first frame for 2 sec , for second frame 10 sec and for 3rd frame 3 sec.
How can I achive this?
one solution can be variable frame rate for each frame. CAn we do this in wmv ? How can we do this? Is there any other alternative available to achive this
All help and guidelines are welcome
Thanks in advance
Regards,
Hemant.

Can't you keep a constant frame rate?
In your case one frame-per-second would work. So when you write the video stream you'd write
2 frames of the first image, 10 frames of the second image, and 3 of the third image.
Are you using a Video Image stream or a regular video stream for your wmv file?

What is difference between "Video Image stream" and "regular video stream"?
|
|
|
|
|
A video image stream is made up of still images. The stream is written differently than
regular "live" video when using the windows media sdk to write wmv files.

// something extra
}

Dear all
I use AfxBeginThread in one dll program. this thread is responsible for logging data.
When I debug program, I trace until I reach the AfxBeginThread Line .
program dont continue and a suspend state begins.
When I debug the program into AfxBeginThread line, I find that When it reachs the
VERIFY(::WaitForSingleObject(startup.hEvent, INFINITE) == WAIT_OBJECT_0);
::CloseHandle(startup.hEvent);
in threadcore.cpp function, the ack of waitforsingleobject never comes and program suspends.
Do you have any idea about this problem.
Best regards
Mahdi

how are you creating the thread ?

I find the reason.
When I call the AfxBeginThread in MFC driven class constructores I see this problem.
but when I call it in another function, I dont see this problem.

Hi all
i have developed a web server. Whenever a client connect to my web server, i create a thread and process the rquest. In my thread, each time i create one COM component(Script engine vbscript.dll)using CoCreateInstance. so i am facing a problem while calling the CoCreateInstance().
Is any good method to avoid frequent calls to the COM component. I mean
one time initializing my engine and using it whenever i need
thanks

why not use this way
CoGetClassObject(rclsid, dwClsContext, NULL, IID_IClassFactory, &pCF);
hresult = pCF->CreateInstance(pUnkOuter, riid, ppvObj)
pCF->Release();
just to call
CoGetClassObject(rclsid, dwClsContext, NULL, IID_IClassFactory, &pCF);
first time it will ensure the dll loading.
then whenever you want to create an instance just call
hresult = pCF->CreateInstance(pUnkOuter, riid, ppvObj)

Hi, i've created a droplist combo box, and listed a few item. Are there anyone who know how to link the clicked item to a certain file saved in text format. I'll then need to send the file to hardware after clicking on the ok button in the dialog box. This is some code that i found in this site. It just shows to get the selection from the droplist. In my dialog box i've created a function to open,browse and load the file. Now i need to figure out how to write the code to automatically link the clicked item in the droplist to a certain text file and also display it in the other function(open,browse and load the file). Also, each item listed in the droplist correspond to different text file. Is there any suggestion on what codes i should add? Is there any article or example that i can refer to? i'm a begineer here.
void CComboBoxTutorialDlg::OnDropListSelchange()
{
UpdateData();
if( m_nDropListIndex < 0 ) return;
CString str;
m_DropList.GetLBText( m_nDropListIndex, str );
CString Out;
Out.Format( "Drop List Selection => index %d\n%s", m_nDropListIndex, str );
AfxMessageBox( Out );
}
thanks in advance

it is better to divide your problem in parts.
1:get selection from combo box
for this you should handle the notification ON_CBN_SELCHANGE
in this handler get the selection with GetLBText()
2: how to relate data
For this purpose you can use GetItemData() and SetItemData()
or GetItemDataPtr() and SetItemDataPtr()
