Hi,

Assuming you are asking @ changing the default value at run time....

In C#

Open the <your setting file name>.Designer.cs. Look for the setting property. If is has only get option add the set option

set
{
this["<your setting name>"] = value;
}

Then you can set the value from your form

Properties.<your setting file name>.Default.<your setting name> = "Your new value";

Properties.<your setting file name>.Default.Save();

Now calling the setting...

Properties.<your setting file name>.Default.<your setting name>;

which will have the new value.

Note: your setting file name = the settings file name without the .settings extension
and this settings file should be in the properties folder.

Use Settings.Save Method. Have a look here: http://msdn.microsoft.com/en-us/library/aa730869(v=vs.80).aspx[^]

Sample:

C#

Properties.Settings.Default.backgroundColor = Color.White;
Properties.Settings.Default.Save();

Cheers!

So many answers are ignored... somehow I spotted this question and your answer (and later fixed my mistake, posted the vote I forgot. That also happens to many commenters :-).
