PostMessage is for (MFC) Windows-GUIs
PostThreadMessage is for threads with a message queue
The shared data idea is really fine. It dimishes uneeded allocating and copying of memory.
allocate shared data and post user message when new data has arrived. Use an array and a flag which data has been read.Press F1 for help or google it.

That is a bad idea.
If you need it sent asynchronously, use a separate thread for this, within which use either SendMessage or SendMessageTimeout - I use both depending on the configuration parameters for timeouts.

Ok so here is the code that I use:
- some init stuff
void MyButton::LoadImageFile()
{
CRect rectBtn;
GetClientRect(&rectBtn);
dc.Attach(this->GetDC()->m_hDC);
Gdiplus::GdiplusStartupInput gdiplusstartupinput;
Gdiplus::GdiplusStartup(&m_gdiplusToken,&m_gdiplusstartupinput,NULL);
m_MyImage = Image::FromFile(L"c:\\icon.png",TRUE);
rect = Rect(rectBtn.left,rectBtn.top,rectBtn.right,rectBtn.bottom);
grpx = new Graphics(dc);
}
- Drawing in OnPaint()
void MyButton::OnPaint()
{
CButton::OnPaint();
grpx->DrawImage(m_MyImage, rect);
}
- Message Map
BEGIN_MESSAGE_MAP(MyButton, CButton)
ON_WM_CTLCOLOR()
ON_WM_PAINT()
ON_WM_LBUTTONDOWN()
ON_WM_LBUTTONUP()
ON_WM_ERASEBKGND()
END_MESSAGE_MAP()
- OnCtlColor
HBRUSH MyButton::OnCtlColor(CDC* pScreenDC, CWnd * wnd, UINT nCtlColor)
{
return NULL;
}
- OnEraseBkgnd
BOOL MyButton::OnEraseBkgnd(CDC* pDC)
{
return TRUE;
}
Image flickers when the focus is set on the button and glowing vista effect is applied or seldom when you fast move over the button with the image.

In a simplicistic approach you may just try to open ports iteratively. The call will fail on not available ports (i.e not existing or busy ones).
 If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

You cannot, as there is no such thing. If you wish to use .NET features from C++ then you must write your program using Managed C++.txtspeak is the realm of 9 year old children, not developers. Christian Graus
