Updating from previous Versions or the Shareware Version

Web Connection is updated frequently and so you'll often have to update an existing installation with the core files from a new version. This topic refers to same version updates (ie. 7.10 -> 7.12 for example).

Updating from the Shareware Version

If you are updating from the Shareware version or you had previously installed the Shareware version, or you have already installed and are seeing shareware version prompts we recommend a full delete of all files in the Web Connection installation folder followed by a full reinstall as a Fresh Install as described below.

Do a Fresh Install!

Web Connection 6.x and later uses a new project system that doesn't write anything of interest into the Web Connection Install folders after installation. So the installation folder doesn't have any files worth keeping between releases and it is safe to delete the installation files and reinstall.

For this reason a complete delete all and reinstall is the preferred way to update a Web Connection installation now.

You can install Web Connection anywhere you like, but the following assumes \wconnect as the install folder.

If you build application using the new project system all application related files will be in your project folders. So it's perfectly safe to:

  • Backup your existing installation to something like \wconnectXXX
  • Delete all content in the original \wconnect folder
  • Reinstall or Unzip Web Connection into \wconnect

There are potentially some files that you may have customized and you may want to copy back from your old install:

  • wconnect_override.h
  • wwSession and WebRequestLog tables
  • Any other files you've explicitly put in the install folder (not recommended)

Once copied we recommend you also run setup.exe again, to update the Visual Studio Addin and Visual Studio and Visual Studio Code templates etc. but this is optional. Setup doesn't touch any of your project files so it's safe to run without breaking existing applications.

If Things Go Wrong

If things don't work out with the new version and you have breaking changes that you don't want to fix, you can easily roll back simply by changing your FoxPro path to point at the old Web Connection folder (ie. \wconnectXXX). In your config.fpw (or in SETPATHS.prg) just use \wconnectXXX\classes;\wconnectXXX instead of \wconnect to point at the old folders.

In Place Update

If you have an older version of Web Connection, or you frequently store custom files in the Web Connection folder you may prefer to do an in-place update. So rather than nuking all the files you'll essentially copy the new version ontop of the old version.

Run the registered version installer and choose the existing installation folder (\wconnect by default). Simply unzip the new files into your old installation directory.

Note that if you've modified any of the samples files, or any of the framework files you won't want to update the existing installation or at least make sure you do a backup prior to installation of the new version. In general doing a back up of the old install is probably a good idea.

After you've installed the new files over the existing installation, make sure you:

  • Delete all FXP files in the project directories
  • Recompile all PRG and VCX files
  • Update DLLs in production apps
  • Update the Web specific files (DLLs, Scripts,CSS)

Recompiling

To recompile all code files to the latest version is necessary to ensure that both the FXP files as well as your project is recompiled. You can do the following from the VFP Command Window in the Web Connection startup directory:

CLOSE ALL
CLEAR ALL
DELETE FILE classes\*.fxp
DELETE FILE *.fxp
COMPILE classes\*.prg
COMPILE CLASS CLASSES\*.vcx

You can also use:

DO CompileWC()  && in '\tools' folder

Shareware Version Update

If you are updating from the Shareware Version and you're overwriting make sure you:

  • Delete wconnect.app
  • Make sure that #DEFINE SHAREWARE .F. in wconnect.h
  • Ensure you recompiled everything as described above

Update DLLs in Production Apps

Web Connection 7 and later uses self-contained projects to hold all resources associated with a Web Connection project - nothing gets stored in the Web Connection install folder, and all support files other than the Web Connection code dependencies are contained within the project's folder hierarchy.

Use the Update Project Wizard (or Console Command)

The easiest way to update projects is to use a new utility in Web Connection 7.12 which lets you update existing projects. There are two ways to do this:

  • Launch the Web Connection Console (DO Console)
  • Choose Update Project Resources
  • Pick a project folder
  • Choose components to update
  • Finish

Alternately you can use a Console Command like this:

DO CONSOLE WITH "UPDATEPROJECTRESOURCES", "\WebConnectionProjects\SecurityTest","modules,dlls,libs,scripts,css,views"

This updates the following:

  • modules - Web Server Integration Module Dlls
  • dlls - Support DLLs for the FoxPro Server (wwdotnetbridge and .net helpers)
  • libs - Web JavaScript and CSS libraries (bootstrap, fontawesome etc.)
  • scripts - Web Connection specific support scripts (ww.jquery.js)
  • css - project specific default CSS file: application.css
  • views - project specific Views (be careful since these you might have changed - back them up)

Manually Updating

The UpdateProjects tooling makes it easy to update relevant components. The following are more details on what is actually updated.

FoxPro accessed DLLS

Web Connection uses a number of DLL files that are distributed in the Web Connection root folder. These files are required in deployed applications and should match the versions that you are running during development.

Make Backups before Updating

Always back up or commit your current application's changes to source control before updating files so you can roll back or copy the old files if necessary.

The DLLs in questions include:

Core Dependencies

  • wwIPstuff.dll
  • wwDotnetBridge.dll
  • Newtonsoft.Json.dll
  • zlib1.dll

General Purpose

  • dzip.dll, dunzip.dll
  • wwImaging.dll

.NET Interop

  • Markdig.dll
  • Renci.SshNet.dll

Of these files wwIPStuff.dll, wwDotnetBridge.dll and zlib1.dll are core dependencies that have to be present as they are used internally in Web Connection.

Newtonsoft.Json.dll is required for all JSON related operations including the wwJsonSerializer, REST Services, wwJsonServiceClient and anything else your code might use to parse JSON.

The remainder of files are specific use cases but I recommend you copy and update them nevertheless.

We recommend you copy all the DLLs from the Web Connection install folder to your live application deploy folder. You can also use the build.ps1 file in Web Connection projects to create a Build folder that includes your binary files along with the Web Connection required dlls in the \deploy folder.

Web Server Integration Modules

These are the Web Server connectors that connect the Web Server to the FoxPro Web Connection Server. That's the ASP.NET Handler, the old ISAPI module, and the new Web Connection Web Server.

These files are copied from \Templates\Scripts into \web\bin.

Copy Web Support Files

You'll also want to update your Web directory support files that provide support images and JavaScript files for the current version. These files should be updated in the Web folder of each application.

Next update scripts, css and Page Templates (selectively):

To do this copy the following:

  • templates\ProjectTemplate\Web\lib -> Web Dir\lib
  • templates\ProjectTemplate\Web\scripts -> Web Dir\scripts
  • templates\ProjectTemplate\Web\css -> Web Dir\css
  • templates\ProjectTemplate\Web\admin -> Web Dir\admin

In addition you should probably also update the stock View Templates in the Views folder:

  • templates\ProjectTemplate\Web\Views -> Web Dir\Views

But be careful here, since it's very likely that you may have modified the templates in these folders.

Important: Always create a backup first and then use a comparison tool like Beyond Compare or WinMerge to check for changes when in doubt.

Important: If you've modified any of the files, they will be overwritten. Especially make sure that you rename application.css in your application to something that is specific to your own application or only overrides styles in application.css.

Update Project Generated Files

When you create a new project Web Connection generates a number of files which is a one time process. These files are generated from templates and these templates occasionally change, so from time to time it's a good idea to check and see what has changed.

A good recommendation if you would like to update these files is:

If you have older projects and you want to update to the latest support files I recommend:

  • Create a new project into a new folder
  • Use BeyondCompare or similar to compare files

You'll want to compare at the following files:

  • build.ps1
  • install-iis-features.ps1
  • deploy\bld_YourApp.prg
  • deploy\yourApp_serverConfig.prg
  • deploy\yourAppMain.prg
