Return value style convenience methods, one-line code to get text/Hex/byte array\r\n\r\n---\r\n\r\n## Core Highlights\r\n\r\n### 1️⃣ Direct Object Reference Event Model 🔗\r\n\r\n**Traditional Winsock control problems:**\r\n`vb\r\n' Need to manage clients via index\r\nPrivate Sub Winsock1_ConnectionRequest(Index As Integer, ByVal requestID As Long)\r\n Dim i As Integer\r\n ' Find available index or dynamically load control...\r\nEnd Sub\r\n\r\n' When processing data, need to know which client\r\nPrivate Sub Winsock1_DataArrival(Index As Integer, ByVal bytesTotal As Long)\r\n Winsock1(Index).GetData strData\r\nEnd Sub\r\n`\r\n\r\n**cWinsock's elegant solution:**\r\n`vb\r\n' Event directly passes client object!\r\nPrivate Sub m_oServer_ConnectionRequest(Client As cWinsock, ByRef DisConnect As Boolean)\r\n ' Directly operate on Client object, no index needed\r\n Debug.Print "New client: " & Client.RemoteHostIP\r\n \r\n ' Reject blacklist IP\r\n If IsBlacklisted(Client.RemoteHostIP) Then\r\n DisConnect = True\r\n End If\r\nEnd Sub\r\n\r\n' Data event also directly passes client object\r\nPrivate Sub m_oServer_DataArrival(Client As cWinsock, ByVal bytesTotal As Long)\r\n Dim sData As String\r\n Client.GetData sData\r\n ' Directly read data from Client object, no index lookup needed\r\nEnd Sub\r\n`\r\n\r\n---\r\n\r\n### 2️⃣ Smart TCP Client Event Proxy 📡\r\n\r\n**Problem scenario:** After server accepts new connection and creates client object, its data reception event cannot be subscribed by host.\r\n\r\n**cWinsock's solution:** Automatically trigger events through parent server object\r\n\r\n`vb\r\n' In server object's DataArrival event\r\n' Can receive data from all clients!\r\nPrivate Sub m_oServer_DataArrival(Client As cWinsock, ByVal bytesTotal As Long)\r\n Dim sData As String\r\n Client.GetData sData\r\n \r\n ' Client parameter is the specific client object\r\n ' Can directly reply to that client\r\n Client.SendData "Echo: " & sData\r\nEnd Sub\r\n`\r\n\r\n**How it works:**\r\n1. Server accepts new connection, creates independent client socket object\r\n2. Client receives data, triggers event via parent server's `RaiseDataArrivalEvent` method\r\n3. Host only needs to subscribe to server object events to handle all client data\r\n\r\n---\r\n\r\n### 3️⃣ UDP Server Virtual Client Management 🎭\r\n\r\nUDP is a connectionless protocol, but `cWinsock` creates virtual client objects for each different remote address:port combination, simulating connection behavior:\r\n\r\n`vb\r\n' UDP server mode\r\nPrivate Sub m_oUdp_ConnectionRequest(Client As cWinsock, ByRef DisConnect As Boolean)\r\n ' Each remote address:port combination that communicates for the first time\r\n ' Automatically creates a virtual Client object\r\n Debug.Print "UDP client: " & Client.RemoteHostIP & ":" & Client.RemotePort\r\nEnd Sub\r\n\r\nPrivate Sub m_oUdp_DataArrival(Client As cWinsock, ByVal bytesTotal As Long)\r\n Dim sData As String\r\n Client.GetData sData\r\n \r\n ' Can reply to specific virtual client\r\n ' cWinsock automatically uses correct target address:port\r\n Client.SendData "Reply: " & sData\r\nEnd Sub\r\n`\r\n\r\n---\r\n\r\n### 4️⃣ Connection Request Interception Mechanism 🚦\r\n\r\nImplement connection interception via `DisConnect` parameter in `ConnectionRequest` event:\r\n\r\n`vb\r\nPrivate Sub m_oServer_ConnectionRequest(Client As cWinsock, ByRef DisConnect As Boolean)\r\n ' Blacklist check\r\n If IsInBlacklist(Client.RemoteHostIP) Then\r\n Debug.Print "Reject blacklist IP: " & Client.RemoteHostIP\r\n DisConnect = True ' Set to True, automatically disconnect and cleanup resources\r\n Exit Sub\r\n End If\r\n \r\n ' Port range restriction\r\n If Client.RemotePort < 1024 Then\r\n Debug.Print "Reject privileged port connection: " & Client.RemotePort\r\n DisConnect = True\r\n Exit Sub\r\n End If\r\n \r\n ' Whitelist mode\r\n If m_bWhitelistMode And Not IsInWhitelist(Client.RemoteHostIP) Then\r\n Debug.Print "Not in whitelist, reject connection"\r\n DisConnect = True\r\n Exit Sub\r\n End If\r\n \r\n ' Keep DisConnect False, accept connection\r\n Debug.Print "Accept connection: " & Client.RemoteHostIP & ":" & Client.RemotePort\r\nEnd Sub\r\n`\r\n\r\n---\r\n\r\n### 5️⃣ Flexible Text Encoding Support 🔤\r\n\r\nSupports multiple encoding methods to adapt to different scenarios:\r\n\r\n`vb\r\n' Default uses ACP/GBK encoding (compatible with VB6)\r\nClient.SendData "中文测试"\r\nClient.GetData sData ' Default ACP\r\n\r\n' Use UTF-8 encoding (recommended for network transmission)\r\nClient.SendData "中文测试", ucsScpUtf8\r\nClient.GetData sData, , , ucsScpUtf8\r\n\r\n' Use Unicode (no conversion, keep wide characters)\r\nClient.SendData "中文测试", ScpUnicode\r\nClient.GetData sData, , , ScpUnicode\r\n\r\n' Send byte array (no encoding involved)\r\nDim baData() As Byte\r\nbaData = GetByteArray()\r\nClient.SendData baData\r\n`\r\n\r\n**Encoding enumeration:**\r\n- `ScpAcp` (0) - System default code page (GBK on Chinese Windows)\r\n- `ScpUtf8` (65001) - UTF-8 encoding\r\n- `ScpUnicode` (-1) - Unicode, no encoding conversion\r\n\r\n---\r\n\r\n### 6️⃣ Automatic Client Collection Management 📚\r\n\r\nIn server mode, automatically maintains all connected clients:\r\n\r\n`vb\r\n' Client collection automatically initialized when server starts\r\nm_oServer.Listen 8080\r\n\r\n' Iterate through all clients\r\nDim oClient As cWinsock\r\nFor Each oClient In m_oServer.Clients\r\n Debug.Print "Client: " & oClient.ClientId & " - " & oClient.RemoteHostIP\r\nNext\r\n\r\n' Get client count\r\nDebug.Print "Current connections: " & m_oServer.ClientCount\r\n\r\n' Manually remove client (usually automatically handled by CloseEvent)\r\nm_oServer.RemoveClient oClient\r\n`\r\n\r\n---\r\n\r\n### 7️⃣ Smart Remote Address Resolution 🌐\r\n\r\nUDP server mode supports domain name resolution:\r\n\r\n`vb\r\n' Set remote address (can be IP or domain name)\r\nm_oUdp.RemoteHost = "example.com"\r\nm_oUdp.RemotePort = 8888\r\n\r\n' Domain name automatically resolved when sending\r\nm_oUdp.SendData "Hello"\r\n`\r\n\r\n**Internal logic:**\r\n`vb\r\n' Smart selection in SendData method\r\nIf LenB(m_sRemoteHostIP) <> 0 Then\r\n ' If resolved IP exists, prioritize using it\r\n m_oSocket.SendText Data, m_sRemoteHostIP, m_lRemotePort, CodePage\r\nElseIf LenB(m_sRemoteHost) <> 0 Then\r\n ' Otherwise use hostname, underlying layer automatically resolves domain name\r\n m_oSocket.SendText Data, m_sRemoteHost, m_lRemotePort, CodePage\r\nEnd If\r\n`\r\n\r\n---\r\n\r\n### 8️⃣ Data Buffer Management 📊\r\n\r\nBuilt-in data buffer, supports partial reading:\r\n\r\n`vb\r\n' When receiving data, only read first 100 bytes\r\nDim sPartial As String\r\nClient.GetData sPartial, vbString, 100\r\n\r\n' Remaining data automatically saved in internal buffer\r\n' Will continue to return remaining data on next read\r\n`\r\n\r\n**Internal buffer mechanism:**\r\n- TCP and client mode: Use `m_baRecvBuffer` private member\r\n- UDP server virtual client: Use `UserData` property for temporary storage\r\n\r\n---\r\n\r\n### 9️⃣ Data Packet Protocol 📦\r\n\r\n**Problem scenario**: TCP is a streaming protocol with data fragmentation and sticky packet issues\r\n\r\n`vb\r\n' Sender sends continuously\r\nClient.SendData "Hello"\r\nClient.SendData "World"\r\n\r\n' Receiver may receive\r\n"HelloWorld" ' Sticky packet\r\n"Hel" ' Fragmentation\r\n"loWorld"\r\n`\r\n\r\n**cWinsock built-in three protocols to solve this:**\r\n- **Character delimiter protocol** (`ppDelimiter`) - Supports custom delimiters (e.g., `\r\n`, `|`, `\0`, etc.)\r\n- **Fixed length protocol** (`ppFixedLength`) - Suitable for fixed-length messages\r\n- **Length header protocol** (`ppLengthHeader`) - Supports 2/4 byte headers, configurable endianness\r\n\r\n**Usage example:**\r\n`vb\r\n' Set character delimiter protocol\r\nServer.PacketProtocol = ppDelimiter\r\nServer.Delimiter = vbCrLf\r\n\r\n' Or set length header protocol\r\nServer.PacketProtocol = ppLengthHeader\r\nServer.HeaderBytes = 4 ' 4-byte length header\r\nServer.HeaderEndian = eeLittleEndian\r\n\r\n' Send automatic packet\r\nClient.SendData "Hello World" ' Automatically append protocol marker\r\n\r\n' Receive automatic unpacket - use MessageArrival event\r\nPrivate Sub Server_MessageArrival(Client As cWinsock, ByVal bytesTotal As Long)\r\n Dim sData As String\r\n Client.GetDataText sData ' Get complete message\r\nEnd Sub\r\n`\r\n\r\n**Key features:**\r\n- Each client has independent protocol instance, buffers isolated from each other\r\n- New clients automatically inherit server protocol configuration\r\n- In protocol mode, **only `MessageArrival` is triggered**, not `DataArrival`, to avoid duplicate reads\r\n- Heartbeat data goes through protocol encoding, does not pollute protocol state machine\r\n- `MaxPacketSize`/`MaxBufferSize` safety limits, prevent malicious packets and memory exhaustion\r\n- UDP clients also support packet protocol\r\n\r\n**Detailed description**: See [Packet Protocol and Heartbeat Mechanism](./packet-protocol.md), [Properties Reference](./properties.md), [Events Reference](./events.md)\r\n\r\n---\r\n\r\n### 🔟 TCP Smart Heartbeat 💓\r\n\r\n**Problem scenario**: TCP connection may silently disconnect due to network issues, need keep-alive mechanism\r\n\r\n**cWinsock built-in heartbeat manager**, embedded `cTimer` auto-drive, no external timer needed:\r\n\r\n`vb\r\n' Server: Timeout detection (default 120 seconds)\r\nServer.HeartbeatTimeout = 120\r\nServer.AutoHeartbeat = True\r\n\r\n' Client: Heartbeat keep-alive (default 50 seconds interval)\r\nClient.HeartbeatInterval = 50\r\nClient.AutoHeartbeat = True\r\n\r\n' Events\r\nPrivate Sub Server_ClientTimeout(Client As cWinsock)\r\n Debug.Print "Client timeout: " & Client.RemoteHostIP\r\n ' Already auto-disconnected, can do cleanup\r\nEnd Sub\r\n\r\nPrivate Sub Client_HeartbeatSent(Client As cWinsock)\r\n Debug.Print "Heartbeat sent"\r\nEnd Sub\r\n`\r\n\r\n**Key features:**\r\n- Embedded `cTimer` (10-second interval), `AutoHeartbeat = True` for full auto operation\r\n- Server: Polls client idle time, auto-disconnects zombie connections on timeout\r\n- Client: Smart skip - skips heartbeat when data send/receive exists, saves bandwidth\r\n- Each send/receive auto-updates `LastActivityTime`\r\n- New clients automatically inherit server heartbeat configuration\r\n- Heartbeat data goes through protocol encoding, does not pollute packet protocol state machine\r\n\r\n**Detailed description**: See [Packet Protocol and Heartbeat Mechanism](./packet-protocol.md), [Properties Reference](./properties.md), [Events Reference](./events.md)\r\n\r\n---\r\n\r\n### 1️⃣1️⃣ GetData Enhanced Methods 🎯\r\n\r\n**Problem scenario**: Getting data requires manual format conversion, code is tedious\r\n\r\n**cWinsock provides return value style convenience methods**, one-line code ready to use:\r\n\r\n`vb\r\n' Directly return text\r\nDebug.Print Client.GetDataText() ' ACP/GBK\r\nDebug.Print Client.GetDataTextUTF8() ' UTF-8\r\nDebug.Print Client.GetDataTextUnicode() ' Unicode\r\n\r\n' Directly return hexadecimal\r\nDebug.Print Client.GetDataHex() ' "48 65 6C 6C 6F"\r\n\r\n' Directly return byte array\r\nDim baData() As Byte\r\nbaData = Client.GetDataByteArray()\r\n\r\n' Condition check\r\nIf Client.GetDataText() = "Hello" Then\r\n Debug.Print "Received Hello"\r\nEnd If\r\n\r\n' Compatible with old method\r\nDim sData As String\r\nsData = Client.GetDataToString() ' Equivalent to GetDataText()\r\n`\r\n\r\n**Detailed description**: See [Methods Reference](./methods.md)\r\n\r\n---\r\n\r\n## Comparison with Native Winsock Control\r\n\r\n| Feature | Native Winsock Control |
