Look at one of the constructor of CString,

CString( LPCWSTR lpsz );<br />
throw( CMemoryException );

PS. Where are you seeing the only one char ?

you didn't get it.
his project certainly doesn't define UNICODE, so his CString is actually CStringA (ansi string - char*).
but he assigns a wide characters string into an ansi string; and wide string contain \0 bytes into some characters, that's why he sees only the first one...

BTW, see my other reply to have a working solution for this pb

The ANSI/Unicode setting doesn't affect the CString ctor that accepts an LPCWSTR.

Or you can just use the CString ctor that accepts an LPCWSTR, as the other posters said.

Are they worker threads or UI-threads?

What mechanism do you use to stop any of them?

Perhaps some excellent articles about how to use threads can be of service: worker threads[^], UI-threads[^].

They are all UI threads
Is it possible to close all of them without using their objects..
like

PostThreadMessage(WM_QUIT,NULL,NULL);

PostThreadMessage(...) is the correct way to end a UI-thread, you're right about that.

It usually desired and considered good practice to wait on the thread handle to make sure that the thread has finished and delete the CWinThread object afterwards.
The articles I linked to in my previous post will show you how.

However, this requires that you keep track of all threads in some kind of container, e.g. std::vector.

yeah you have to post same to all the object which are representing the UI thread

Keep the boolean var that keeps the loop running global. It does the job for you.
Use the same variable to control the loops in all the threads. Setting that to false would let every thread jump out of the loops. And in the end you can check using the Wait functions to see if everything's closed properly. For that you need to maintain the handles in a structure as Roger just mentioned.

I can't subclass the Button on MessageBox. Why ??

...............
SetWindowsHookEx(WH_CBT,(HOOKPROC)CBTProc.........
...............

LRESULT CALLBACK CBTProc(int nCode, WPARAM wParam, LPARAM lParam)
{
if(nCode == HCBT_CREATEWND)
{
HWND hWnd = (HWND) wParam;
LPCBT_CREATEWND pcb = (LPCBT_CREATEWND) lParam;
CWnd * pWnd = NULL;
TCHAR szClassName[255] = _T("\0");

GetClassName( hWnd, szClassName,sizeof(szClassName) / sizeof(TCHAR) );

if(! lstrcmp(szClassName, _T("Button")))
{
CButtonST pNewButton = new CButtonST;
if( pNewButton )
pNewButton->SubclassWindow( hWnd );
}
}
return CallNextHook( nCode, wParam, lParam);
}
But, I can't subclass MessageBox's Button. Why ??
