CTcpClientPtr Client Send() returned TRUE, but data cannot be transmitted.

[mnt-github]

Through several tests, i verified that there were no errors in the socket server.

Code is below.

// ClientSocket.h
#include "HPSocket.h"

class ClientSocket : public CTcpClientListener
{
    bool ConnectSocketToServer(const char* szAddress, unsigned short usPort);
    ...
    CTCPClientPtr m_pClient;
    ...
}



// ClientSocket.cpp
#include "ClientSocket.h"

#ifdef WIN64
#ifdef _DEBUG
#pragma comment(lib, "../../HP-Socket-Dev/Windows/Lib/HPSocket/x64/static/HPSocket_D.lib")
#else
#pragma comment(lib, "../../HP-Socket-Dev/Windows/Lib/HPSocket/x64/static/HPSocket.lib")
#endif
#else
#ifdef _DEBUG
#pragma comment(lib, "../../HP-Socket-Dev/Windows/Lib/HPSocket/x86/static/HPSocket_D.lib")
#else
#pragma comment(lib, "../../HP-Socket-Dev/Windows/Lib/HPSocket/x86/static/HPSocket.lib")
#endif
#endif

ClientSocket::ClientSocket()
    : m_pClient(this)
{
}

bool ClientSocket::ConnectSocketToServer(const char* szAddress, unsigned short usPort)
{
    m_pClient->SetSocketBufferSize(MAX_PACKET_SIZE);
    if (!m_pClient->Start(szAddress, usPort))
    {
        return false;
    }
    return true;
}

EnHandleResult ClientSocket::OnReceive(ITcpClient* pSender, CONNID dwConnID, const BYTE* pData, int iLength)
{
    BYTE* pReplyData = NULL;
    DWORD dwReplyDataLen = 0;

    // ... Recv Procession ...

    // Reply Data
    if (!m_pClient->Send(pReplyData, dwReplyDataLen))
    {
        m_pClient->Stop();
    }
}

The data is transmitted the first time, but not again after that.
I defined HPSOCKET_STATIC_LIB at Project Property Page -> C/C++ -> Preprocessor -> Preprocessor Definitions.

Please, Help me.

m_pClient->Start(szAddress, usPort) is async connect by default.
Data can only be sent after receiving the OnHandShake event.

[mnt-github]

// ClientSocket.cpp

EnHandleResult ClientSocket::OnConnect(ITcpClient* pSender, CONNID dwConnID)
{
    // try to authenticate
    BYTE auth_packet[AUTH_PKT_LEN] = { 0 };
    ....
    if (!m_pClient->Send(auth_packet, AUTH_PKT_LEN))
    {
        m_pClient->Stop();
        return HR_OK;
    }
}

AUTH_PKT_LEN is 40 bytes. Only Auth data is transmitted.
After this, any data is not transmitted.

m_pClient->Send() always returned TRUE.

Use system ::GetLastError() to get error.

and if OnSend event fired, means that send ok.

[mnt-github]

Use system ::GetLastError() to get error

::GetLastError() returned 0.

[ldcsaa]

OnSend event triggered?

[mnt-github]

OnSend event triggered?

Yeah, When first AUTH data is transmitted, OnSend event triggered.
After then, not triggered.

Previously, when I developed by loading the source code of HPSocket, Data communication worked properly.
There are too many include errors when loading the gdiplus library, so i had changed HPSocket Static Library.
From then on, this problem occurred.

try dynamic library ...

And the include files version must match the library version.

What's HP-Socket version ?

Sorry, How can i check HP-Socket version?

[ldcsaa]

version defined in HPTypeDef.h
or

// 获取 HPSocket 版本号（4 个字节分别为：主版本号，子版本号，修正版本号，构建编号）
HPSOCKET_API DWORD HP_GetHPSocketVersion();

[mnt-github]

version defined in HPTypeDef.h or

// 获取 HPSocket 版本号（4 个字节分别为：主版本号，子版本号，修正版本号，构建编号）
HPSOCKET_API DWORD HP_GetHPSocketVersion();

In HPTypeDef.h, version defined as 6(Major).0(Minor).1(Revise).6(build)
And HP_GetHPSocketVersion() returned 100663558.
100663558 is correct?
