How can I setup a button that will toggle the language while the program

running? It seems once it's running, changing the language has no effect.

The language is processed in the Constructor of the Form. So once a form
is already constructed, it won't change language. After you change the
Thread.CurrentT hread.CurrentUI Culture, new forms that you open will show in
the new language, but the form itself from which you executed that change,
as well as any previously opened forms, will not change. You can close and
reopen the current form if you want it to show in the new language.

Re: Changing Localization on the fly

Localization data(strings and other data if any) are stored in satellite
dlls. So, once a dll is loaded, you can't unload that dll and load
another dll. The only way to change that (as far as I know) is to
restart your application. It applies to both .Net applications and MFC
applications.

Hi Greg,

you can change it, look how it's done in
Windows Form Designer generated code.

Basically it's working like this:

private void localize(Cultur eInfo culture)
{
Thread.CurrentT hread.CurrentUI Culture = culture;

foreach (Form form in Application.Ope nForms)
ApplyControlRes ources(new
ComponentResour ceManager(form. GetType()), form);
}

private void ApplyControlRes ources
(ComponentResou rceManager resourceManager , Control control)
{
if (control is Form)
resourceManager .ApplyResources (control, "$this");
else
resourceManager .ApplyResources (control, control.Name);

if (control is IContainerContr ol)
{
foreach (Control childControl in control.Control s)
{
ApplyControlRes ources(resource Manager, childControl);
}
}
}

Additional, you have to iterate through each forms menus and do the same.

RE: Changing Localization on the fly

Hi Greg,

Walter has provided a great solution to this question.

This solution works because the ComponentResour ceManager.Apply Resources
will load the resource dll at runtime. It will not impact the performance
because the loading will only happen in the first time to apply the
resource and later the resource dll will stay in memory.

Please try Walter's solution and let us know if you have any problem when
implementing it. Thanks.

Have a look at the following article on code project:

Code Project

http://www.codeproject.com/KB/cs/CultureManager.aspx

Code Project - For Those Who Code

It provides a component that allows you to change the active culture
of all forms/controls in your application.
