Yes, that is NOT the case. You'd need to pass a NULL parameter.

As a first step, simply I found the number of spaces in a string and the length of it. So I can count number of characters there.
No I want to calculate number of words there. So I want to find a combination a space and immediately follows a character. Because that's the start of a word. How can I detect that combination? Any comments.
I appreciate your help all the time...

you can test the value of a character like (buf[x] == 'c')
there are also C runtime functions like isdigit() that you can find in the documentation

hey im working on video processing project bt i need help in capturing
frames from an video of .dat format
*** we will specify the path of video file and den the code should access that video
and capture frames from it and den store the captured frames from dat video at
the location where we will specify.

You will need the specs for the .dat file...
there's lots of proprietary .dat formats - I don't
know of any standard formats.

nywys even if u can tell me frame extraction for any type of video it would be
helpful to me....

specs == specifications.
What's in the file? You can't extract frames if you
don't know where they are in the file or what format
they are in.

im considering an sports video here bt it wont matter wat video file we r takin
we are having the video file from which we hv to extract frames
as a video file is nothing but sequence of frames..eg: 1 sec video will hv around 24/30 frames
so the task is to take snapshots of the video as the timepasses,so here we hv to take atleast
24/30 snapshots in 1 second to get good no of frames those can be processed....
hope nw the prbml is clear..plz help me for this..

I would start with clearly defining the steps you need to take
to accomplish your task. It's still unclear to me.
This is what I have so far:
Open the file
Loop until done:
Read a video frame
Do something with the video frame
Close the file

We are having an application which is interacting with the static library(Default library) and in turn this will interact with the DLL.
This is written on the application side
*****************************************
CNodeView *node_view = NULL;
node_view = m_default_mgr->GetGUI(node); (the call goes to
if (NULL == m_pMainVseqEditor)
return;
if (!IsWindow(node_view->m_hWnd))
{
CRect rectView = CRect(0,0,700,500);
// create the window
if(NULL == ((CWnd*)node_view)->Create(NULL, NULL, WS_CHILD | WS_VISIBLE, rectView , m_pMainVseqEditor, 14567))
The create function will work fine in debug mode but in release mode this return NULL.
Let me know how to resolve this issue in relesse mode.
Is there any specific project settings are there?

Did you check GetLastError()? You could also check it by adding @err,hr in watch window. I hope it could give you some hint.

First parameter takes the window class name for e.g. WC_EDIT, you have given nothing here, shouldn't you give your CNodeView's class name. You must have a used RegisterClassEx or AfxRegisterWndClass for this purpose.

What type is node_view? You use it in the IsWindow() call
like it's a CWnd*, so why do you cast it to a CWnd* when you
call the Create() method?
Is m_pMainVseqEditor->m_hWnd valid at the Create() call?
For clarity, FALSE is a better macro to use than NULL when you're
comparing a BOOL (IMO).

Hi,
I am using a ClistCtrl which is to be filled with the data coming from server. As it is taking some time so there is flickering of window.
I want that while the data is being fetched a dialog should appear with progress bar along with the message Downloading.
Can any one help me.
Thanks In advance

You may use a worker thread to perform the data acquisition and send messages to the progress bar window in order to update its status.

Since you are frequently adding data to your list ctrl, flickering is usual. Use LockWindowUpdate() and UnLockWindowUpdate()to lock the control. Check here[^] about how to use it.

Create a model-less dialog with progress bar and display it. Define a custom message by RegisterWindowMessage() and utilize it to update progress to ProgressDialog.

Are you sure it's not something with your machine? Have you checked if it's working with regular apps like notepad, etc.? Do they work in a fresh new SDI project?
