### Blocking Pseudo Code Example

Source: https://wiki.overbyte.eu/wiki/index.php/Asynchronous_Paradigm

Demonstrates a blocking pattern that fails with non-blocking ICS components because execution continues before the connection is established.

```text
Connect;
Send(Something); 
```

### Use Name method in C++

Source: https://wiki.overbyte.eu/wiki/index.php/TemplateProp

Example of calling the Name method within a C++ loop to perform a dummy operation.

```cpp
for (int n = 0; n < 10; n++) { 
 BusyString += Coffee->Name(BusyString);
 }
```

--------------------------------

### Implement ReceiveStr in OnDataAvailable

Source: https://wiki.overbyte.eu/wiki/index.php/TWSocket.State

Example usage of ReceiveStr within an OnDataAvailable event handler.

```Pascal
 procedure TMySocket.MyOnDataAvailable(Sender: TObject; ErrCode: Word);
 var s    :String; // received packet
 begin
   if ErrCode <> 0 then
   begin
     exit;
   end;
 
   s:=ReceiveStr;
 end;
```

--------------------------------

### Initiating Non-Blocking Connection

Source: https://wiki.overbyte.eu/wiki/index.php/Asynchronous_Paradigm

Shows how to assign an event handler and initiate a connection in an asynchronous environment.

```pascal
**procedure** TForm1.MySendData;
**begin   ** 
    WSocket1.OnSessionConnected := WSocket1SessionConnected;
    WSocket1.Connect;
**end**;
```

--------------------------------

### Use Name method in Delphi

Source: https://wiki.overbyte.eu/wiki/index.php/TemplateProp

Example of calling the Name method within a loop to perform a dummy operation.

```delphi
for n := 1 to 10 do 
BusyString := BusyString + Coffee.Name(BusyString);
```

--------------------------------

### Redistribute SSL Certificate Domain

Source: https://wiki.overbyte.eu/wiki/index.php?action=edit&title=FAQ_Order_SSL_Certificates

Initializes a TWSocket instance and configures connection parameters after referencing the custom-built ICS DLL.

```csharp
 using OverByte.Ics;
 using OverByte.Ics.Units;
 
 lSocket = new TWSocket(null);
 lSocket.Addr = "127.0.0.1";
 lSocket.Port = "10001";
 lSocket.LineMode = true;
 lSocket.OnSessionConnected += new TSessionConnected(lSocket_OnSessionConnected);
 lSocket.OnDataAvailable += new TDataAvailable(lSocket_OnDataAvailable);
 lSocket.Connect();
