I have recently bought a new laptop running windows 8. I have installed Visual Studio 2012. I am getting type conversion errors when I should not. Can anyone tell me if this is an installation error for Visual Studio ?

VB

Public Class Form1

    Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
        Dim n As Double = Convert.ToDouble("256.234")
        Debug.Print(n)
    End Sub
End Class

When I run the code above, I get the following error.

"FormatException was unhandled - input string was not in a correct format."

This makes no sense..

Hello,

The Convert.ToDouble(string) interprets the value is using formatting conventions of the current thread culture. Please see MSDN documentation (http://msdn.microsoft.com/en-us/library/zh1hkw6k.aspx). Check the regional Settings of your machine and verify the formatting.

Thank you ! You were right. My regional settings had "," instead of "." for decimals. changed it and now my application works again.
