In particular you should check out these equivalent API 2. Since this was posted, there have been many updates to Xojo. If you have not already, try these new Xojo Framework classes in your projects. Input = Xojo.IO.TextInputStream.Open(openFile, 8) ![]() 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. T = t + kEOL + ContentsOfDictionary( entry.The first classes in the new Xojo Framework have been available for all project types since Xojo 2015 Release 2. Xojo uses a proprietary object-oriented language. of Austin, Texas for software development targeting macOS, Microsoft Windows, Linux, iOS, the Web and Raspberry Pi. T = t + if( entry.Value, "true", "false" ) + kEOL The Xojo programming environment and programming language is developed and commercially marketed by Xojo, Inc. ![]() How do I call the method ContentsOfDictionary? dim dict as = (kJsonData)įor each entry as in dict Here is a link to the test file I am using. If I use ContentsOfDictionary in an action button, I get this error:Įrror: Not Enough arguments: got 0, expected at least 1 The method ContentsOfDictionary accepts the parameters d as and level as an integer, and returns text. I have the code below in a View method to parse JSON files.
