Question: I am trying to store some persistent application data so I've added a setting to the project by R-Clicking on it, selecting properties, then Settings tab and manually entering settings name, Type, Scope and Value

When I run the code, I read settings like this: 

`lastRunTime = My.Settings.LastRunTime` 

and set it like this:

`My.Settings.LastRunTime = lastRunTime`

Where can I actually see the new setting? Because for the love of God, I cannot see where it is updating the setting. app.config has the original setting value when I created that setting. So where can I see it? 

When I run the code, I see it updates it and the next time I run the app the new value persists, so I know it stores it somewhere. But where?

Answer: 
That value is stored in the APPDATA folder under your user profile. For Windows 7 look in C:\Users\\AppData\Roaming\

There will be a folder named based on how you configured Visual Studio. Since my copy at work is registered to the company, the default value is my company name. Since my copy of Visual Studio at home is registered to myself, the default value is my name. 

AppData is a hidden folder, that won't show up if you navigate via Windows Explorer. But if you type it into the run command it will open with no problems.
Since you did 

```
My.Settings.LastRunTime = lastRunTime
My.Settings.Save() '-----------------> maybe you forgot this

```

I'm sure you can read the setting with ..

```
lastRunTime = My.Settings.LastRunTime

```
