handle

Good evening :-)! I have this code to use Drag & Drop method for files : TForm1 = class(TForm) ... public procedure DropFiles(var msg: TMessage ); message WM_DROPFILES; end; procedure TForm1.FormCreate(Sender: TObject) begin DragAcceptFiles(ListView1.Handle, True); end; procedure TForm1.DropFiles(var msg: TMessage ); var i, count : integer; dropFileName : array [0..511] of Char; MAXFILENAME: integer; begin MAXFILENAME := 511; count := DragQueryFile(msg.WParam, $FFFFFFFF, dropFileName, MAXFILENAME); for i := 0 to count - 1 do begin DragQueryFile(msg.WParam, i, dropFileName, MAXFILENAME); Memo1

_beginthreadex returns a handle to a thread: m_hStreamStatsThread = (HANDLE) _beginthreadex( NULL, 0, StreamStatsThread, this, 0, NULL ); This handle may be used if you need to refer to the thread in calls like TerminateThread(..) for example. According to the MSDN page on _beginthreadex , _beginthreadex won't always return a valid handle - e.g. it may also return -1L on error etc. When a thread has completed normally, do I have to call CloseHandle on the thread handle, or can I just set its value to NULL / INVALID_HANDLE_VALUE? Agree with Nemanja Trifunovic. Even after the thread exited - its

I have some handle and I need to close it. There is some places in code, where handle may be closed. So, is this a right way to close handle? HANDLE h; .... if ( h != INVALID_HANDLE_VALUE ) { ::CloseHandle(h); h = INVALID_HANDLE_VALUE; } There is a same question about bitmap handles: HBITMAP hb; .... if ( hb != INVALID_HANDLE_VALUE ) { ::DeleteObject(hb); hb = INVALID_HANDLE_VALUE; } EDIT: I think, there is some misunderstanding. I know CloseHandle is for closing handles. I'd like to know proper way for closing handles. A similar situations occurs with deleting of pointers. Foo *foo = new Foo(

I'm going to learn how to handle HTTPS traffic in C# as server-side and as for the first steps I've got some troubles. Here is some code ( http://pastebin.com/C4ZYrS8Q ): class Program { static bool ValidateServerCertificate(object sender, X509Certificate certificate, X509Chain chain, SslPolicyErrors sslPolicyErrors) { if (sslPolicyErrors == SslPolicyErrors.None) return true; Console.WriteLine("Certificate error: {0}", sslPolicyErrors); return false; } static void Main() { var tcpListener = new TcpListener(IPAddress.Parse("127.0.0.1"), 8080); tcpListener.Start(); var clientAccept = tcpListener

Curious about how the handle STDERR works? Lets keep it down to say Batch Files to keep it simple and focused? I know that many programming languages accept STDERR, so I don't know if maybe uses are different across the board or maybe there is a common function for all programming languages? If anyone can provide some examples on common usage that you have seen or an explanation of why someone may utilize it for ??? situation that would be awesome. Thanks in advance! Usually you would use stderr for error messages. If you run a program on the command line, you can capture its stdout and/or

How do I convert a handle acquired from a form/control's Handle property, to a IWin32Window^ ? Control.FromHandle (That gets you the Control object, which implements the IWin32Window interface.) Eg. IntPtr myWindowHandle = IntPtr(someVal); IWin32Window^ w = Control::FromHandle(myWindowHandle); Note that this relies on the handle being "acquired from a form/control's Handle property." You cannot use this technique with an arbitrary Win32 window handle. There's a simpler method that is supported directly by the .NET framework without having to create your own custom class. You can use this with
