Seems there is two cultures(languages) installed on the Windows. For example en-us (English) and Chinese and we can changed the language by Alt+Shift as you know. I need to show the selected language. For example if Chinese is selected when I click on a button on windows form, a massage box show me Chinese is selected. Like this:
if(culture == "en_us")
{
messagebox.show("English");
}
else
{
messageBox.show("Chinese");*
}
