West Wind Internet & Client Tools
for Visual FoxPro

West Wind Client Tools is a suite of FoxPro classes that provides rich Internet functionality to FoxPro applications. The library also includes many useful utility classes for every day FoxPro development tasks.

The Internet features include SMTP Email support, full featured HTTP Web access, FTP file transfers and management, low level TCP/IP access and a host of Internet support functions. The client utilities components like a light weight business object framework, an easy to use SQL client library, a .NET integration library, powerful FoxPro based scripting class, XML conversion routines, and a number of very rich generic utility libraries for common everyday FoxPro tasks.

This tool provides most of the client and everyday development functionality of our West Wind Web Connection product, and is an upgrade to the functionality of the West Wind Internet Protocols suite, the functionality of which is integrated into this package. All of the client tool features also are part of the West Wind Web Connection product.

Although a number of the tools included in this package are available from various sources and articles were previously published by Rick Strahl, this package combines them into a single, fully documented, frequently updated and supported package.

The following classes and tools are provided:

Internet Functionality:

  • SMTP and POP3 Email support
    SMTP Send Mail capability both in blocking synchronous and asynchronous modes. Support for file attachments, CCs and BCCs, special content types (HTML or XML messages for example) and more. All you need is a mail server to send message through (your ISP's or your own) and off you go. POP3 support provides a separate class to handle mail retrieval with an easy to use interface to retrieving, parsing and managing messages in a POP3 mailbox. The latest version also supports SSL based connections.

  • HTTP - Access Web content from VFP
    Need to grab any content from the Web in your applications? Retrieve Web page content for screen scraping, talk to REST , POX or other Web Service APIs, submit and drive Web based forms and send XML or binary data from client to server and back. wwHTTP is a complete HTTP client libary for FoxPro that lets receive and send data over the Web using HTTP with great ease. Send URLEncoded POST data to servers, upload huge files via HTTP, access SSL, handle GZip encoded and authenticated content. Best of all it's very easy to use: all it takes is two lines of code to retrieve content and only a few additional lines to POST content to a server.

  • Advanced HTTP support
    In addition, tools required for efficient HTTP operation are also included such as fast URLEncoding/URLDecoding using fast C code routines, binary packaging for DBF files for transfer over HTTP, a GZip decoding and encoding component, as well as inclusion of the powerful wwXML class which can be used to convert VFP cursors and objects into XML.

  • FTP - Transfer files
    New updated wwFTP class allows for file downloads and uploads. Low and high level methods for simple transfers and control over the connection are supported. Use active and passive FTP. Note: Secure FTP is currently not supported.

  • Low Level TCP/IP Socket Access
    Create low level TCP/IP socket connections and create socket servers with with the wwSocket class to access Internet or TCP/IP services. This class is very easy to use and includes high-level methods that session and transaction based TCP/IP access very easy.

  • Dial up Networking
    Basic support for dialing and disconnecting a RAS Dial-up Networking Connections.

  • IP Address validation
    Support for domain lookup from IP address and IP Address from domain name.

  • Fast C based Conversion Routines
    UrlEncoding and UrlDecoding, UTF-8 Conversion, Base 64 encoding.

Data Access Classes and Support Classes

  • wwBusiness Class
    The wwBusiness class is an extremly easy to use, single level business object class. It implements both the business and data tier in a single object to provide ease of use and maximum performance. The base object provides core data access functionality (Load, Save, Query, New etc.) through its base class methods. Query based data access is also supported through native Fox syntax or using the class methods which can route to the appropriate backend. Fox or SQL Server are natively supported. SQL Server is supported with SQL Passthrough commands. Remote Web data is also supported against any FoxPro based Web backend (Web Connection, ASP+COM, FoxISAPI etc.) Web data can run against a SQL backend (with some limitations a Fox backend can be used as well).

  • wwSQL Class
    The wwSQL class is a light-weight wraper object around SQL Passthrough in Visual FoxPro and provides handle abstraction and a simplified interface to executing SQL commands and managing connections. The class provides error handling and error recovery for connection issues as well as a number of high level methods that deal with updating data and passing data between Fox and SQL backends. There's also a wwADOSql class that works through ADO to provide Unicode support in database access using the exact same syntax as wwSQL.

  • wwDotNetBridge Class
    Access just about any .NET component from Visual FoxPro and do it without requiring COM registration. The library allows access to components not supported with plain COM Interop such as enumerations, value structures, generic types, arrays and collections and a host of common but COM unsupported types. wwDotnetBridge removes many of the limitations of .NET COM Interop and allows you to tap into the full power and features of the .NET framework.

  • wwHTTPSQL/wwHTTPSQLServer Web SQL Class
    The wwHTTPSQL class provides a Web based remote SQL Engine to VFP client applications. The wwHTTPSQL -> wwHTTPSQLServer pair allows an application to query data from a Web server and return this data in standard VFP cursor format. Data travels over the wire as XML and is transparently converted. The server can be implemented in any VFP code capable Web development tool (Web Connection, ASP, FoxISAPI, AFP etc) and allows remote execution against VFP or any ODBC datasource on the Web server. Ever wanted to run Visual FoxPro as a remote SQL Engine? This is one way you can do it. Very easy to install and access with only a few lines of code.

  • wwXML Class
    wwXML is a powerful data conversion class that lets you convert Fox cursors and object to and from XML. This class is more flexible than VFP 7's native commands and provides a number of additional features including direct support for .NET datasets and of course the ability to persist and restore objects.

General Purpose Classes

  • wwScripting Class
    The wwScripting class is a dynamic ASP like (<% %>) dynamic scripting engine that lets you do template merged scripting at the speed of fully compiled FoxPro code. wwScripting takes your scripts/templates and turns them into full FoxPro PRG files that are cached and execute at the full speed of Visual FoxPro. Templates can be modified at runtime and changes be detected in real time for maximum flexibility without loss of performance. Great tool to add dynamic scripting or HTML rendering to your applications.

  • wwSOAP Class
    wwSOAP is a FoxPro based SOAP implementation that provides both client and server side SOAP formatting. This class is very flexible in dealing with SOAP servers of various flavors and has better support for .NET Web Services than the MS SOAP toolkit. The class also includes a supplementary WSDL parser that exposes the Web service using simple a simple Fox class hierarchy, and an additional SoapHelper class provides the ability to create WSDL files (both from Fox classes and COM object) and create proxy classes from WSDL definitions programmatically.

  • wwAsyncWebRequest Class 
    Provides a powerful databased messaging class that makes it easy to pass asynchronous requests and messages between different applications. Works both with Fox and SQL Server Data. Can be used instead of MSMQ for a more easily managed and more flexible solution when two way messaging is required. Perfect for building truly distributed and message based (SOA style) applications.

  • wwPDF Class
    Easily create PDF documents from FoxPro reports using any of the supported drivers using either Adobe Acrobat Distiller, GhostScript, XFRX, AmyUni or ActivePDF.

  • wwImaging functions
    Use these functions to create thumbnails or resize and rotate images, retrieve image info or set JPEG compression level on a variety of image types. Provides a small wrapper around some basic GDI+ functions that are very easy to use and fast. Also includes function to create a CAPTCHA image for user input validation on Web Pages.

  • wwCollection Classes
    FoxPro includes a collection class but unfortunately that class is hobbled by many issues including horrible performance and the inability to trap for missing elements without generting errors. The wwCollection classes provide a base collection (value only) class, a name value collection and stack classes. Classes are managed through arrays and provide many useful features not found on the built-in collection class.

  • wwCodeUpdate - Update your Applications
    This useful class provides everything needed to have your applications check for version information online (in an XML file) and download and install updates. The class provides for online checking of the latest version available, version comparision, file download via HTTP, swapping files and restarting the current application.

Utility Classes

  • wwConfig  -  A very useful configuration utility that can persist data from an object into a configuration file (XML, INI or the registry) and can be used in any application as a single access configuration manager object.

  • wwCache - A cache class that allows you to easily cache string results for later reuse. Very useful especially for Web applications where content or partial content can be easily cached for reuse.

  • wwXMLState - This class can be used to manage dynamic properties inside of a string or memo field. It's XML based and stores multiple values in a single string. Useful for extending database schemas without changing the structure and to store data more efficiently when data is sparse and would waste space as a field.

  • wwWebGraphs - This class provides a very easy way to generate various types of charts (bar, line, point, pie etc) from VFP cursors or arrays. Uses the Office Web Components to create flashy graphs with very little code and without having to deal with the OWC object model.

  • wwEval - A 'safe execution' class that can be used to run user specified or unknown code. Sort of a poor man's Try/Catch implementation that allows you to run code that potentially could fail safely and receive error information. Execute single commands, expressions and even entire code blocks. Also includes MergeText() functionality to parse script like pages using ASP style syntax.

  • wwLocaleInfo - Very useful class to retrieve all location specific information (date time formats, delimiters, currency symbols etc.) about a given locale.

  • wwJSONSerializer - JSON is JavaScript Object Notation and is frequently used with AJAX applications to pass data from the server to JavaScript clients running in the browser. This class provides for Serialization of FoxPro types to and from JSON. Works with all simple types, most complex types, simple arrays and object collections as well as with serializing FoxPro cursors.

  • wwUtils and wwAPI Libraries - These extensive function libraries contains a variety of general purpose functions from text formatting, to HTML formatting, to debugging, COM configuration, viewing output in various text formats and even several GUI pop up routines. The API library abstracts many often used Windows API functions in simple wrappers.

Useful Tools
