![]() For example, this prompts the user for a file and then opens it using a TextInputStream: Dim f As FolderItem = GetOpenFolderItem("")ĭim openFile As New Xojo.IO.FolderItem(f.NativePath.ToText) You can even use these classes with classic FolderItems by first converting them to Xojo.IO.FolderItem. The TextInputStream and TextOutputStream make it easy to deal with encodings because the encoding is part of the method calls. Lastly, I often work with Text files which means I have to deal with encodings. I recently did a webinar that shows how to use HTTPSocket with a variety of web services. This is a big advantage over the classic HTTPSocket which only supports HTTP 1.0 making it not always compatible with some sites. Creating JSON text from a Dictionary is one line of code: Dim jsonText As Text = (myDictionary)Īnd converting JSON text to a Dictionary is also one line of code: Dim jsonDict As = (jsonText)īoth of these methods are much faster than using JSONItem in the classic framework. In the new framework, JSON is handled by two methods ( and ), typically with. Return leftText.Compare(rightText, Text.CompareCaseSensitive) JSON can also be case-sensitive which is not even an option with the classic Dicitonary class! You just have to subclass (or use AddHandler) and implement the CompareKeys event handler: Dim leftText As Text = lhs MyDictionary.Value("Name") = "Bob Roberts"įor Each entry As In myDictionary ![]() I prefer because it is has an easy-to-use iterator, making it crazy-simply to loop through the items in the Dictionary: Dim myDictionary As New For example, you store the Caption of a button as Text: Dim t As Text = Dictionary If you have a String (such as a property of a UI control) you can easily convert it to Text by calling the ToText method. MyButton.Caption = t // converts automatically to String For example, you can set a button Caption using a Text variable: Dim t As Text = "Hello" You can easily use Text with your existing projects as a Text value converts back to a String automatically. ![]() When you need to send the Text to a file, DB or elsewhere, you convert it to data using whatever encoding is appropriate- usually UTF8. Once it is in Text, you don’t worry about the encoding. When you get data from an outside source (a file, a database or even a String), you specify the encoding so it can be stored as Text. Essentially if you use Text, you don’t have to worry about the encoding. The new Text data type is a substitute for String and has the benefit of making encodings easier to work with. Many software vendors do not publish the binary formats that their apps use to create documents.The first classes in the new Xojo Framework have been available for all project types since Xojo 2015 Release 2. If your own app created the file, you will know this, but if the file was created by an app you didn't write, you may not know it. In order to read a binary file, you must know how the data is arranged. The format is the arrangement of data within the file. You can also read and write anywhere in the file without having to read through all the data preceding the data you want.Īlthough text-based file formats are increasingly common, many apps also store data in a binary format. For example, you can open a binary file, read some data, then write some data, and close it. In a binary file, this number can be written as a short integer (or just “short”), which requires only 2 bytes.īinary files also have the added benefit that you can read and write to a file without having to close the file in-between, as is required with text files. For example, the number 30000 stored as text requires 5 characters of text to store in a text file, which can be 5 or more bytes depending on the encoding.
