regarding the strict C++ programming language, nothing avoids you to code for MAC OS, Windows, Linux/Unix, Symbian or whatever else Operating System.
The only constrain is the compiler.
as long as you can find a compiler (of a Cross-Compiler) for the OS you want to target, then go for it

Of course.
BTW: Why don't you try Google to find out relavant info? For instance, a quick search gave me this page [^].

I am calling void SearchDialog::OnSearchBtn() from a thread. The error flashes @ statement UpdateData(TRUE);
The instruction at "0x00000000" referenced memory at "0x00000000". The memory could not be "read".
Please advice
class SeachDialog
{
....
....
protected:
// Generated message map functions
//{{AFX_MSG(AssetSearchDialog)
static afx_msg void OnSearchBtn();
....
static UINT StartWorkingThread (LPVOID param);
....
typedef struct THREADSTRUCT //structure for passing to the controlling function
{
SearchDialog* _this;
} THREADSTRUCT;
.....
....
}
UINT SearchDialog::StartWorkingThread (LPVOID param)
{
THREADSTRUCT* ts = (THREADSTRUCT*)param;
ts->_this->OnSearchBtn();
...
...
}
void SearchDialog::OnSearchBtn()
{
UpdateData(TRUE); // RUN TIME ERROR...
..
}

You can't calls things like UpdateData from within a thread. MFC classes should not be shared across threads and you shouldn't access anything on the UI from your thread.
Instead, you should (if I understood what you are trying to do) start the thread when the user presses the 'search' button and pass all the relevant information to the thread, so that it doesn't need to query it from the UI.

More specifically, the dialog box window likely hasn't been initialized at the time you called OnSearchBtn().
In addition to the previous solution, you could send a user message to the dialog box from the thread. I'm doing that in an application I'm working on right now.
In OnSearchBtn(), you should wrap the function contents in if (GetSafeHwnd()) {} to ensure it's only called when the window is valid.
(As a small note; to prevent problems in my current application I don't start the worker thread until the dialog box has been created. I do this by setting a short timer in OnInitDialog().)
Anyone who thinks he has a better idea of what's good for people than people do is a swine.

Why don't you use a CFormView[^] instead?

You don't have to use a bitmap. Paint the background of the
window however you want to.

I want to implement a recorder just like the windows recorder,however, what I want is only the sound strength but not the wav file recorded. How could I do?
|

As you're capturing audio samples, you can iterate through
blocks of samples to find the peak amplitude. You could use
a progress bar to show the level or draw it some other way.
I personally use a variable that the audio capture thread updates as
samples are captured. A periodic timer (on the UI thread) takes care
of rendering the level.
