Brain Patchwork DX, LLC. - DXSock Suite

TBPDXNewConnect

TBPDXSock Connect method, for establishing a connection to a server (listener). It contains 11 properties.

Free Pascal

   TBPDXNewConnect = Object(TBPDXComponent)

Delphi

   TBPDXNewConnect = Class(TBPDXComponent)

Methods

None. Only contains constructor and destructor.

ConnectTimeoutUSEC

ipAddress

The IPAddress or fully qualified machine and domain name. Internally the code will evaluate this property to handle name to IP, or to see if the request is for a Linux/Mac OS X processor file handle.

Port

The port number is the port the remote server (listener) is accepting connections on. In most operating systems there is a SERVICES file which denotes all standard ports. If you are developing a test application (both server and client) you should use ports above 1024. In reality, you should use ports above 65000 to avoid conflict with other products who have registered their ports already.

UseBLOCKING

DXSock support both Blocking and Non-Blocking socket calls. A blocking call will not return control to your application until the socket layer has performed the requested task. This includes routines which under some operating systems can take up to 2 minutes to timeout. In non-blocking mode, the call to the socket layer is returned immediately. This allows DXSock to evaluate the return code, and if possible retry the command automatically based upon best practice. Another difference to note is non-blocking calls use a little more CPU time than non-blocking calls.

UseNAGLE

Enables or Disables the use of

Nagle.

UseUDP

Enables or Disables the socket to be used for

UDP/IP communications. This will set RDP, IPX, SPX, TCP and ICMP to false.

UseRDP

Enables or Disables the socket to be used for RDP/IP communications. This will set UDP, IPX, SPX, TCP and ICMP to false.

UseIPX

Enables or Disables the socket to be used for IPX communications. This will set UDP, RDP, SPX, TCP and ICMP to false.

UseSPX

Enables or Disables the socket to be used for SPX communications. This will set UDP, RDP, IPX, TCP and ICMP to false.

UseTCP

Enables or Disables the socket to be used for

TCP/IP communications. This will set UDP, RDP, IPX, SPX and ICMP to false.

UseICMP

Enables or Disables the socket to be used for ICMP communications. This will set UDP, RDP, IPX, SPX and TCP to false. On Linux/Mac OS X you must have root permission to enable your socket layer to go into promiscuous mode. On Windows, many version of Winsock do not support RAW socket mode and you will have to rely on a different DLL to support ICMP calls.
