We've here the unlucky situation that the recorded message includes the last DTMF-tone that was used to stop recording (voice-mail system).
Since we cannot prevent this DMTF-tone being written, the only solution is to strip the last 200-500ms from the recorded WAV-file afterwards. This action can be done when the WAV-file has been closed.
My question now is:
Has anybody an idea and/or reference how to strip 200-500ms from a WAV-file? Example code? I've load programming expeerience (kernel development), but fideling in WAV-files is completely new to me.
All WAV-file parameters are already known and fixed.
Thanks a lot!

The files are written in chunks of data following the WAV file specification. There is an api with several functions beginning with 'mmio' you can use to more easily manipulate the files.
So, then, use the api and re-write the file leaving off the last 200-500 ms, or else truncate the parts of the data and re-write the header portions appropriately controlling the last chunk(s) in the file.
If you know the data size, sampling rate, etc. it should be easy to calculate how many trailing samples to discard to drop off 200-500 ms.

In my project,there are a lot of global members.
To my surprise that I found two of the global member has the overlapped memory address.
For example:
member a begin at address 0x00457280 and the size of a is 14D(hex)
member b begin at address 0x00457380 and the size of b is 848(hex)
obviously the two member overlapped!
But why?I have no idea on finding out a solution!

Can you tell more about that variables, how are declared and so on...?

Unless your code accepted the connection, received the "virus" bytes, knew that it was executable
code of some kind, and executed the code, then it didn't come through your socket.

I used to handle the OnPaint message:
void CDlgPPAGMain::OnPaint() <br />
{<br />
CPaintDC dc(this);
CRect r, r2;<br />
<br />
if( GetSafeHwnd() != 0 && m_clctrlParamsRobotSel.GetSafeHwnd() != 0)<br />
{<br />
GetClientRect(&r);<br />
m_clctrlParamsRobotSel.GetWindowRect(&r2);<br />
ScreenToClient(&r2);<br />
<br />
r.bottom = r2.top;<br />
<br />
dc.FillSolidRect(r,0x000000);<br />
}<br />
}
Sure that this is not the best method, but it works.

what is m_clctrlParamsRobotSel?
|
|
|
|

Don't worry on that, this is a piece of code that I've used and I've not removed anything, this is a variable that refers to a listcontrol that has the same width of the entire dialog, in your case you should get the size of the dialog client are and then paint it.

CRect r;<br />
<br />
if(GetSafeHwnd() != 0)<br />
{<br />
GetClientRect(&r);<br />
dc.FillSolidRect(r,0x000000);<br />
}<br />
}
this should be ok for you...

yes thats working well. how we can change the background color of tab control.

Hey! that's new, I've re-read the first post, in order to do that there is an article here in the CP that explains how to do it. I promise you that I don't remember how to do it, but I've seen a post regarding to that this same week here in the VC forum.
Try to search for that, sure that it will work for you.

Hello,
I have an application which is not having the document - view architecture and here the ChildFrame is derived from CMDIChildWnd and the ChildView is derived from CWnd.
Can I derive the view from CSrollView ?
And if I cannot derive from CScrollView will I be able to add the scrolling capabilities myself

Did you answer the question ?
Yes I am confused

No. I was mainly just wanting some clarification about your "I have an application which is not having the document - view architecture...Can I derive the view from CSrollView ?" comment. You can't have both.

Hello,
You mean to say if I don't have document-view architecture than I cannot derive my view from CScrollView.
Is that so
Prithaa
|
|

You apparently have two requirements: 1) not to use the doc/view architecture, and 2) derive a view from CScrollView. Can you not see how #2 contradicts with #1? You can do either, just not both in unison.
