WinsockNet how to link two fixed IP to communicate with the machine-CodePudding

 Public Function WinsockNet () 
Mainform. SysWinsock (0). Close 
Mainform. SysWinsock (0). The RemoteHost=m_sWritingServerIP 
Mainform. SysWinsock (0). The RemotePort=Val (m_sWritingServerPort) 
Mainform. SysWinsock (0). The Connect 
End the Function 
The Public Function WinsockNet_2 () 
Mainform. SysWinsock (1). The Close 
Mainform. SysWinsock (1). RemoteHost=m_sWritingServerIP_2 
Mainform. SysWinsock (1). RemotePort=Val (m_sWritingServerPort_2) 
Mainform. SysWinsock (1). The Connect 
End the Function

I present links directly with the above two 2 IP
But the two IP can be connected, is not necessarily so I use the following code for reconnection

 If mainform. SysWinsock (0). The State & lt;> 7 Then 
Network interruption m_lpSysWarningTwo=m_lpSysWarningTwo Or MCA_DATASERVER_UNCONNECTED '
Call WinsockNet 
End the if 
If mainform. SysWinsock (1). The State & lt;> 7 Then 
Network interruption m_lpSysWarningThree=m_lpSysWarningThree Or MCA_DATASERVER_UNCONNECTED_TWO '
Call WinsockNet_2 
End the if

But now when I SysWinsock even (0), the received information is normal, but when I SysWinsock (1) even when not SysWinsock (0) receiving less than information
Could you tell me how to write this kind of situation the link of program

CodePudding user response:

TCP reconnection mechanism of the water is deep, deep,
Try every time before reconnection delay for 30 seconds,
