I'd like to do "on the fly" compression during a recording from sound card.
I know how to record into PCM .wav file. I don't want to use codecs
to compress but LAME or oggenc external programs.
But still I can not figure out how to pass in data, I just got from sound card buffer, into for example LAME.
..somehow from stdin ?
I can not use lame dll, i need it more flexible.
Does anyone know some example?
Thank you

If I understood your question clearly; is this what you want ?

::SendMessage(GetDesktopWindow(),WM_RBUTTONDOWN,wParam,lParam);

Hi,

Use SendInput or mouse_event function to emulate mouse actions.

I have started using VS 2005 for my MFC C++ applications, however I get loads of warnings, mainly the use of strcpy.

Are they a simple guide for moving up to VS 2005, I am having problems with strcpy etc.

I get in a mess if I just change to strcpy_s.

Also keep getting told to use new options to suppress these warnings, but they dont seem to make any difference.

Any suggestions please.

Because it's unsafe. Use strcpy_s() instead.

Why? Can you work around it with a #define directive?

Thanks for your post. strcpy works in some places but not others.

If I use it here in this module I get an error:

strcpy_s(pchData, LPCSTR(signalName));<br />
<br />
1>c:\mcs_am_emu\am_emu\am_e\signaldlg.cpp(1135) : error C2660: 'strcpy_s' : function does not take 2 arguments

This confuses me!?!

That's because you have to specify length of the destination buffer. It's all about securing from buffer underruns.

strcpy_s(pchData, put_length_of_pchData_here, LPCSTR(signalName));

Reading tree-view control of frontpage

frontpage has a option to open a web thru file-open web command.
it displays a tree view control. i wanted to read the text of the root node in the control. so i tried the following:

1) HTREEITEM htitem;
htitem=TreeView_GetRoot(hWnd); //hWnd is the handle to the tree control
2) char Buf[80];
TVITEM tvitem;
tvitem.mask=TVIF_TEXT | TVIF_HANDLE;
tvitem.hItem=htitem;
tvitem.pszText=(LPSTR)&Buf;
tvitem.cchTextMax=79;
3) SendMessage(hWnd, TVM_GETITEM, 0, (LPARAM)&tvitem);

but this fails. why?
following works:
1) int cnt=SendMessage(hWnd, TVM_GETCOUNT, 0, 0);
2) SendMessage(hWnd, TVM_SELECTITEM, TVGN_CARET, htitem);

if this works, why tvm_getitem fails?

can anyone help?
thanks

Just a guess, but I suspect that Buf needs to be on the heap.

char *pBuf = new char[80];
tvitem.pszText = pBuf;

Hi there

Its for extreme beginners, I think. I was expecting like how do I add some more controls in it, how do I make it work, etc. The article just shows how to make one SDI app. I will be thankful if you can provide me with the required. Thanks for your time. Please note that I have a fair knowledge of working with dialog based apps.

One way is to derive the view from CFormView.

How to move a file

Hi,
I want to move a file in my system to a remote system.

For example I have a file "abc.wav" in my system . Now I want to move this file to another remote system's subdirectory(say "c://xyz").
IP of the remote system say "1.2.0.4".

Can anyone help me.
Thanks in advance.

use sockets for that purpose with file reading,u will find the code on code project as well just search "Network Transfer of File".
thing u had to do is read a file from computer and send to another using sockets where other side will receive and then write on file in this way the transfer will take place.

you could also attach to a share on the other machine eg \\1.2.0.4\c$\xyz either programmatically or through a script to map a drive, then copy the file there using copyfile()

bit lower tech than using the socket suggestion ...

What about MoveFile() or SHFileOperation()? If neither of them accepts a UNC path, you can make use NetUseAdd() to map a drive letter to the remote share.
