Hello,

We all know we can get the size of a TidMessage instance by first saving it to a TMemoryStream and read TMemoryStream.Size to get the size of the email message in bytes, but this doesn't sound performance-friend.

Is there an alternative way to get the size of a Tidmessage object?

Thanks.

Starting with version .14, the following link breaks something in the IW application if is compiled with http.sys:

I use an IdUDPServer to open multiple Ports like this:

Hello,

Is there is a way in IW to setup a cluster that when a session is opennedcan be used by any server in the IW cluster?

The main reason behind this question is the complexity behind setting up a load balancer with sticky sessions.

I'm using IW 14.2.7 with D XE5 as ISAPI

Thank you

Hello guys.

What should I make to be able to fast forward audio or video files using intraweb ? I'm using Central Guest components as well with the same behavior. O ask them and they told me that it's a server feature called "206 partial content" that is not been generated by the server to the browser.

How can I configure this on intraweb ?

Pessoal

Alguém sabe como faço para avançar um arquivo de audio que estou tocando pelo componente IWAudio ? Hoje ele começa tocar mas se eu clico no meio da linha do tempo para avançar ate aquele ponto ele simplesmente ignora meu clique. Na segunda vez ele vai pq ja está em cache.

Me disseram que está faltando um "206 Partial content". Alguém sabe como configurar isso no intraweb ?

Howdy All!

 I am trying to hook to a bootstrap region OnScroll event and then have it fired back to a C Builder OnEvent to let me know if the use has scrolled to the bottom of the window.

The problem is that I am obviously not calculating the scroll position with the right object in my javascript event. My question is how do I in a generic OnEvent() in javascript reference the object that the event is executed for (i.e. like the Delphi Sender object)?

Here is what I have:

1) In my form's OnCreate() event, I have the following code:

  // this is the JavaScript function that we want to call.
  // This function, in turn, will call IWForm2.DoMyAjaxFunc()
  TStringList * pJS = new TStringList;
  pJS->Add(L"function OnWindowScroll()");
  pJS->Add(L"{");
  pJS->Add(L"  var myData;");
  pJS->Add(L"  if ($(this).scrollTop() + $(this).innerHeight() >= $(this)[0].scrollHeight - 20)");
  pJS->Add(L"  {");
  pJS->Add(L"    myData = 'eof = true';");
  pJS->Add(L"  }");
  pJS->Add(L"  else");
  pJS->Add(L"  {");
  pJS->Add(L"    myData = 'eof = false';");
  pJS->Add(L"  }");
pJS->Add(L"executeAjaxEvent(\"&data=\"+myData, null,\"" + UpperCase(Name) + L".OnWindowScroll\", false, null, false);");
  pJS->Add(L"return true;}");
  PageContext->ExtraHeader->Add ( UnicodeString().sprintf ( L"<script language=\"javascript\" type=\"text/javascript\">%s</script>",
  pJS->Text.c_str()
                                                        )
                            );

  // If we want to call IWForm2.DoMyAjaxFunc, then we have to register it as a Callback
  WebApplication->RegisterCallBack(UpperCase(Name) + L".OnWindowScroll",OnWindowScroll);


2) In a button OnAsyncClick event, I attach the above event to the region that I want to check the scrolling of:

// Create dialog
pTermsAndConditionsFrame_ = new TTermsAndConditionsDialogFrame(this);
pTermsAndConditionsFrame_->Name = L"TermsAndConditionsDialogFrame" + IntToStr((int) GetTickCount());

// Hook region's onscroll event...
pTermsAndConditionsFrame_->ModalBodyRegion_->ScriptEvents->HookEvent(L"onscroll",L"OnWindowScroll();");


pTermsAndConditionsFrame_->Parent = this;

3) The registered OnWindowScroll() is always called.

Thanks in advance,

Shane

Hi,

I have TidSmtpServer setup and running, it runs fine for a period of time, then stops responding.  When I set the server active := True it creates 2 threads for each IP binding I have made.  Each of these IP's do for a period of time handle incomming requests as expected.  Then slowly each IP stops responding to external requests and the 2 threads created when the server was set to active appear to terminate. 

The bindings all are still set, and restarting to server (Active set to False then True) does not solve the problem.

I presume that since it is the Listener Threads that are failing we should expect to see the onListenException be fired when that occurs, however I never see this get called.

I am troubleshooting a WiFi UART<=>TCP socket bridge device and I need to verify the arrival times of packets sent via the UART input to the device at the TCP client end.
So in this case I will be sending packets of data via the serial link to the device starting at exactly 1 s intervals.
The packets are rather short, basically date/time strings in pure ASCII like "20181109" and "13:46:17"
My test strings start with STX and end with ETX bytes (0x02 and 0x03 respectively).

Each second the date and time packets are sent back-to-back and then nothing until the next second.
Speed is 38400 baud.

I am using FreePascal 3.0.4 and Lazarus 1.8.0 with the indylaz package installed on a Windows 7 x64 laptop.

Since the data arrive at times the client does not control and indy is blocking I have trouble implementing this checking utility...
What I need is:
- Connect the TIdTCPClient object to the bridge device on port 2101 (this is not a problem)
- Somehow start listening for incoming data
- When a packet has arrived transfer it to the main application for timing and logging purposes.


Probably this needs some kind of thread or a loop with Application.Processmessages, but I am not sure how to approach this...

Any advice available?

I have already implemented a configuration utility for the same WiFi bridge device using Indy, but that only had to deal with handshakes with a command sent from the client and a response being sent back almost instantly.
These commands are not started with STX but ended with ETX.
So this is implemented as follows (excerpt from config utility code), hopefully I could re-use some of that code:

Hello,

I'm trying to call a URL that have a security information from server (IW ISAPI) to another server directly without executing a JS or open a new window at the client.

I Tried IdHTTP, and winnet without success. Both gives unkown error when executed from IW form. Is there is a way to make this call directly from the user session, wait for the results, and then move on accordingly?

I'm using IW 14.2.7 with D XE5


Thx in advance...
