An Installation & Distribution Control/Component by WeOnlyDo! Inc.

General information

wodAppUpdate component should be used by your application to quickly, easily, and securely provide automatic update solution - very popular "check for updates" functionality. This way you increase value and functionality of your product because now your customers always have the most newest version - and you need only 3 lines of code to provide it! wodUpdate uses configuration file it finds on the server of your choice (HTTP, HTTPS or FTP) and then determines if local files need to be replaced or not.

You can send any additional information via URL to the server - and that way determine if user is allowed to update the application, if he uses regular licensed version etc - using your own server-side scripting. wodUpdate doesn't really care what you send and what do you do on the server side.



Simple server-side script

wodAppUpdate expects to get simple text back that contains information about available files on the system, something like this:

#Update file signature

[File]
Name=UpDemo.dll
URL=http://www.weonlydo.com/AppUpdate/test/UpDemo.dll
Version=1.0.0.2

[Message]
ID=17
Caption=something
Text=some text



Three steps to get updated

1. wodAppUpdate should receive configuration file like above as a result of Check method call. This simple configuration data provides all the information wodUpdate needs. Now it will determine if 'UpDemo.dll' needs to be downloaded or not.
2. You can call Download method to download the file locally.
3. Just call Update method to replace it - and restart your app if necessary.

During the process you can control wodUpdate's behavior. You can change file versions, their paths, you can force them (not) to be downloaded by setting NeedReplace property - etc.. You (or the user that uses your application) can cancel ongoing update anytime you want. You can hide wodUpdate and silently perform the update, or you can use our own progress window and show it to end-user. wodUpdate will not initiate anything by itself, still you have full control, but it tries to make it as simple for you as possible, and yet very effective. You can also make your own dialogs since wodUpdate provides interface to integrate your application fully into the update process.



Leave a message to your user

wodAppUpdate can be also used to provide "admin messages" to your users. You can prepare message and store them on the server, and your application can show them to the user.
