NET framework offer an a quick and easy option for storing and accessing data for your application. While far from perfect and a bit overly complicated, Visual Studio and the. The tip here is use the Synchronize button anytime you change the values in the Visual Studio Settings pane. This button will sync the config files and delete and create new nfig files if you have any User scoped values. And to remedy that problem, Microsoft provided a Synchronize button in the Visual Studio Settings pane as well as programmatic controls. Well the reason is because they do get out of sync. Or perhaps you are one of the many developers who gave up on using the app.config file because it never seemed to work or would pull up the incorrect values when accessing them in code. If you been able get this far without falling asleep, you have probably pondered the concept that with so many files holding the same data that things could get out of sync. Any User scoped values will be read from the nfig mentioned above. config file are Application scoped values. These values will be saved in a file named app.config in your project folder and in a file named. For each value you will choose the data type, scope and a default value. There you can define one or more values to be used by your application. Go to your project properties, then click the settings tab on the left. If you need the application so save the value at runtime such as a user preference, then choose User as your scope, otherwise you would choose Application as the scope. User – is read / write at runtime values are saved at the Windows user account level and good for user prefs.Application – is read-only at runtime you can edit a value and have the app use without recompiling.You also define a data type such as string, integer, date, even special types such as connection string. The following examples are using Visual Studio 2008 and VB.NET.Įach value you want to use in your application is defined as simple name=value pairs and saved in special XML files. C# code uses a slightly different syntax the concepts are similar. Once common example is saving database connection string information in a configuration file so that it may be changed without need to recompile the application. NET framework using Visual Studio can take advantage of built-in tools to simplify or speed up access and saving of runtime values. We used to save our application or user settings in an INI file (dark ages) or more recently in XML files using our own code or classes borrowed from other developers.
