Globalization in Windows Forms - Application with multi language support

This blog is the continuation of .Net Globalization blog.
If you want to have a global market for your project then you have to plan for implementing multi language support.

Create a form as shown below.










Add Another form. This is the form whose language text we are planning to change based on the selection from the combobox of first form. Give English Texts to Form and Controls.










Select the form set the Localizable property to True and Language to French(France).

















Now select the existing controls and change its Text property to corresponding French equivalent as shown in the figure.



















Go back to the first form where you can select the language.
In this form we are going to change the culture of the current thread based on the culture
Explanations and additional information will follow soon.


using System.Globalization;
using System.Threading;

private void cboLang_SelectedIndexChanged(object

sender, EventArgs e)
{
if(cboLang.Text == "French")
Thread.CurrentThread.CurrentUICulture = new

CultureInfo("fr-FR");
else
Thread.CurrentThread.CurrentUICulture = new

CultureInfo("en-US");

}

private void btnShowForm_Click(object sender, EventArgs

e)
{
frmLang fl = new frmLang();
fl.Show();
}

VB .Net

Imports System.Globalization
Imports System.Threading

Public Class Form1

Private Sub cboLang_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cboLang.SelectedIndexChanged

If cboLang.Text = "English" Then
Thread.CurrentThread.CurrentUICulture = New CultureInfo("en-US")
Else
Thread.CurrentThread.CurrentUICulture = New CultureInfo("fr-FR")
End If

End Sub

Private Sub btnShowForm_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnShowForm.Click

Dim fl As New frmLang
fl.Show()
End Sub

End Class


Now when you run the application, select French from the ComboBox and click show form the French form will appear and when you select English, English form will appear.
