To download a file, you first define the folder Item and then pass the Key and FolderItem. TheFolderItemUpload = theS3.FolderItemUpload( "Contacts/F30BB9DD-DE9A-4F13-91B1-79BA4A776585/PhotoURL/" + theFolderItem.Name, theFolderItem )ĭownload a FolderItem via a Key. To upload a file, you first define the folder Item and then pass the Key and FolderItem.ĭim theFolderItem as FolderItem = ("test-one.png")ĭim theFolderItemUpload as string // 200 is successful Internally, this method calls ListGetXML and transforms the data into a Dictionary for easier processing. Get a Listing of Content, technically Files and Folders via a Key as a Dictionary. Get a Listing of Content, technically Files and Folders via a Key as XML. Amazon has a ton of information about S3. In our database we have a Table called "Contacts" that has a record with that UUID and a column called "PhotoURL" which stores the key and the filename that was most recently updated which might look like "Contacts/F30BB9DD-DE9A-4F13-91B1-79BA4A776585/PhotoURL/PhotoOfHal.png". This how we store files for a specific Contact Photo. In the List Files example below, we're looking for what is in the "PhotoURL" folder which is in the UUID "F30BB9DD-DE9A-4F13-91B1-79BA4A776585" folder which is in the "Contacts" folder. S3 uses Keys to reference files and folders.

Just set your Keys, update the Region, Domain, and set your Bucket name. Once you drag the class to your project you can instantiate S3. Once you have your Amazon account created, enabled S3 and add an S3 Bucket, I'd suggest using an App like CyberDuck to connect to S3 as a viewer to see the result of making calls to the S3 Class.

First initialize the class then start making calls!īefore getting into the calls, I'd like to have a big thank you to Tim Dietrich and Christian Schmitz for their example code which made putting the S3 Class together super easy. In Xojo its an instance of a particular class ( Application ConsoleApplication WebApplication) Its a subtle difference but its there.Using the S3 Class is easy. Xojo’s biggest add ons come in the form of plugins from a small set of plugin authors.

They range from tiny ones to entire much larger ones like Jasper Reports, and to full blown IDE’s. With that in mind, Xanadu has been rewritten almost from scratch using the Xojo Web Framework 1.0, meant to be a base to build upon when Xojo ships Web Framework 2.0. 1 Web CustomUI uses a subclass of the native Xojo controls. At XDC 2018, Xojo demoed a major update to Web Apps which move to Bootstrap responsive apps with faster communications between the app and the browser and all new controls. Start to use CustomUI in your WebApps with less than 10 minutes of preparation and coding. Use the included Web CustomUI Converter project to easily prepare your WebApps to use CustomUI. In java you can probably find an add on package or classes for just about anything. Custom UI is now compatible with Xojo Web Applications. Xojo name spaces are about as close as you get but they cant be external if they contain deep hierarchies of modules & classes which makes them harder to manage In java classes can be arranged into packages and easily used & imported. Java, like Xojo, is very OOP oriented and classes form the backbone of that OO orientation.īot java and Xojo share a lot of characteristics in how this works.īoth only support single inheritance - a class cannot inherit from two parents like in C++.īoth support Interfaces and use them in very similar ways.
