Just simply add the string in .resx file and assign it a value.
for example.
$this.Text Form1
>>$this.Name Form1
>>$this.Type System.Windows.Forms.Form, System.Windows.Forms, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089
>>button1.Name button1
>>button1.Parent $this
>>button1.Type System.Windows.Forms.Button, System.Windows.Forms, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089
>>button1.ZOrder 0
button1.Text abcdef
this is what i get after setting localization to true.
this content to be written in the .resx file.
