All processes (applications or DLLs) that call Winsock functions must initialize the use of the Windows Sockets DLL before making other Winsock functions calls. This also makes certain that Winsock is supported on the system.

I have been trying to run the Http Listener in a program but cannot use it as the ports are locked under the User options. I have been looking into using a winsock option (AxWinsock) in place of the listener. I have got the main part of the program modified but are finding it hard to get. Hi, I think you can use System.Net.Socket, it is bettter. WINSOCK Control with VFP Using the WINSOCK control with a Visual Fox Pro application is very similar to using it with a Visual Basic application. The main difference is the syntax used. The previous VB examples can be rewritten for a VFP application as follows. Establishing a Connection thisform.Winsock1.Protocol = 0. Winsock Visual Foxpro Software StelsDBF - fast DBF JDBC driver (dBase, XBase, Visual FoxPro) v.5.1 StelsDBF is a DBF JDBC type 4 driver that allows to perform SQL queries and other JDBC operations on DBF files (dBase III/ IV/ V, xBase, Visual FoxPro ). SMTP/POP3/IMAP Visual FoxPro email component library (SEE4FP) uses a simple API to send and receive mail, including HTML and MIME attachments. How to get shaders for minecraft windows 10 edition mod. Comes with many Visual FoxPro examples.Supports all versions of 32-bit Visual FoxPro.

I need example source code in Visual FoxPro, for connect a client with a server in a remote computer via a TCP port, using MS WinSock OCX. I'd like to be able to send and receive some data. Thanks in advance.

To initialize Winsock

Create a WSADATA object called wsaData.
Call WSAStartup and return its value as an integer and check for errors.

The WSAStartup function is called to initiate use of WS2_32.dll.

The WSADATA structure contains information about the Windows Sockets implementation. The MAKEWORD(2,2) parameter of WSAStartup makes a request for version 2.2 of Winsock on the system, and sets the passed version as the highest version of Windows Sockets support that the caller can use.

Add Winsock Functionality to your Visual Basic Application

PowerTCP Winsock for ActiveX includes TCP, UDP, Daemon, DNS and Ping controls for Visual Basic (VB6) and other COM supported environments such as VC++, Delphi and PowerBuilder. PowerTCP provides the building blocks you need for basic or complex Internet application development. Looking for secure TCP? Check out PowerTCP SSL for ActiveX.

Consulting and Custom Development

From custom protocols to complete client-server solutions, let our experienced staff help with your TCP/IP project.

TCP control can be used to implement standard upper-layer protocols (such as WHOIS and Time), as well as any custom protocols you want to develop.
UDP control can likewise be used to implement standard upper-layer protocols (such as Network Time Protocol), as well as custom protocols that use datagram-level communications.
Daemon control accepts incoming connections, then TCP controls can be created on new threads, implementing custom multi-threaded server applications.
DNS control is implemented directly (does not use Winsock services), so you can do address look-ups, reverse address look-ups, and mail address look-ups (from MX records).
Ping control checks if a host is reachable.
Supports COM+ Component Services.
Can be used in a multi-threaded environment.
Includes a royalty-free license.
Wrapper classes included for convenient integration into Visual C++.
Use in COM-supported environments like Visual Basic (VB6), VC++, Microsoft Office VBA (Word, Excel, etc), Delphi, PowerBuilder and more.

Application	Description
Debug Server	This server application is based upon one of Dart's own internal testing tools and is designed to help developers debug their client-side applications by being able to see the message sent from a client application. Then, a developer can respond to the client application with a customized response message sent from the server.

ASP (Online) Samples
Our ASP samples give a live, onsite demonstration of our tools.

Sample Name	Sample Description	Environments
DNS on the Web	ASP application uses the DNS Control to resolve a host name to an address, an address to host name(s), or an email address to a mail server name and address.	COM, .NET
