String to Double issues in C# .NET

If you are simply using 

double test = Double.Parse("12.45");

and it doesn't work due to formating issues, here is the right post for you. Almost certainly you're using the wrong CultureInfo. Try specifying CultureInfo.InvariantCulture to parse in. I suspect it's currently assuming that "." is a thousands separator rather than a decimal point.

CultureInfo Invc = new CultureInfo("");

Invc = CultureInfo.InvariantCulture;

x1 = Double.Parse("12.45", Invc);

alternative:

x1 = Double.Parse("12.45", CultureInfo.InvariantCulture);

2-  Click the controls sequentially to establish the tab order you want.

3 - When you are done, click View - Tab Order to deactivate the indexing.
