SetWindowText() is waiting for a CString, so there's no reason for casting back into a C-style string (LPCTSTR).

idiot question, but, what about using the debugger to see the state of the variable str before and after the operation ?

I'm not sure if it wroks, but you can try this:

m_Edit.SetWindowText((CString) str+"W");

Mmmmh... IMO this is no good code practice. Better use the temp variable.

Well, the only difference between my example (if it works) is that the compiler creates a temp CString, instead of the programmer.
Not much of a difference, IMO.

in fact, to remenber it in the future here are the tips :

(CString)str
this is a C-Style cast (explicit cast of str to CString)

CString(str)
this calls explicitely the CString constructor that get a parameter of the type of str, to create a temporary object that will be passed then to the calling function (in our case).

hope this is helpful Wink | ;)

Problem in storing G.729 Decoded audio

Hello All

I am writing an application to store the RTP packets payload to audio files.

Now I am working on G.729 Codec. I am storing decoded G.729 payload in .WAV file. But the audio converstation is not stored properly.

I hope Decoding is done properly (Function is not returning ERROR). Extracting the payload is proper.

WAV file header details what I am stroing
Compression Code : 1 (PCM/uncompressed)
Channel: 1
Samples Per Sec: 8000
Bits per sample: 16

Let me know is my procedure is correct? After decoding let me know what is the format of the audio we get?

My application works fine for G.711 codec.

Thanks for your time
Ravi

Hai,could any one pls help me out.....
I have statically created a splitter window with 2 views one is derived from CTreeView and the other from CListView.Then i have managed to insert items into the tree view retrieving from the database. Now i want to insert some columns into the listview but i couldn't do so since the style of the list view is to be LVS_REPORT . But, initially the style is LVS_SMALL.I don't find any way to change this style property using msdn functions.

Please tell me either how to change the style property or how to insert the columns into the listview as above.

Change the style:
m_List.ModifyStyle(0,LVS_REPORT);

Insert a few columns:

m_List.InsertColumn(0,"abcd");<br />
m_List.InsertColumn(1,"efgh");

this is this.

How to get output from speaker?

I need to display some visualizations base on output sound from speaker.
How could I do that? (No DirectX)

Get a flipchart and a pen. Open the flipchart and pump up the sound. Then, each time you hear a drum, move your pen up and down, while, during the song, slowly moving your pen from one side of the chart to the next.

If you do not want to use DirectX, try using an A/D-converter to feed your data back to the PC (USB or Legacy Ports).

Cheers,
Sebastian

If I was you, I would try, lets say, the Audacity source. Audacity is an open-source sound/wave editor/filterset, which might save you a lot of work.

They should do something like that somewhere.

If I was to record my own sound on the computer, I would retrieve the input from "Stereo Mixer" (which should also contain every sound your computer currently is playin, because it remixes the output stream into the input stream.

Sebastian
