.NET Forum / Windows Forms / WinForm General / February 2006Update Application Settings
When I create aplication settings using the settings editor, they are read only. So how can I update them? :) BTW, why they are read-only?

Eric, Which Version of .NET are you using? In .NET 1.x MS thought it was a good idea not to provide a simple way to update the Config files without using the DOM, but... not many of us liked that. In .NET 2.0 you should be able to read and write to the config file. Can you post the error you are seeing?

Error 8 Property or indexer 'WindowsApplication1.Properties.Settings.Teste' cannot be assigned to -- it is read only SignatureErick Sasse >> Which Version of .NET are you using? > [quoted text clipped - 6 lines] >'WindowsApplication1.Properties.Settings.Teste' cannot be assigned to >-- it is read only Hmm.. Sorry, but would you mind posting the code you are using to set the value? Thanks, Otis Mukinfus http://www.otismukinfus.com http://www.tomchilders.com > Hmm..

No problem. :) Properties.Settings.Default.Teste = textBox1.Text; If you take a look at this article, the author talk about application settings being read-only: http://msdn.microsoft.com/msdnmag/issues/06/00/SmartClients/ SignatureErick Sasse Change setting type (aka Scope) from "Application" to "User" in the settings editor for each object you need to have write access. With Scope set to Application, those objects will be readonly. > Change setting type (aka Scope) from "Application" to "User" in the > settings editor for each object you need to have write access. With > Scope set to Application, those objects will be readonly. Ok, but then if a user updates a setting it don't propagate to other users, right? I want to have app settings that a user can update. What's the best approach? Thanks! SignatureErick Sasse Correct. It is stored locally. Just don't ask me where or what file. Add a method for setting the value on demand (btnClick) or on exit (formclosing) If SaveMySettingsOnExit = True, you will not need to call MySettings.Save as it will happen automatically on every form close. You will, however, need to set the values. To propagate user settigns on form close, set your variables that you want to propagate to the next session in the formclosing event. ie. MySettings.SettingStr1 = Me.TextBox1.Text
