I would like to automatically change the keyboard layout and I create a simple console application in Visual Basic adding the following:
InputLanguage.CurrentInputLanguage = InputLanguage.FromCulture(New CultureInfo("ru"))
But when I compile this code it doesn't change the keyboard layout, so it remains what it was before compiling. What am I doing wrong?
There three ways to change keyboard language:
Using property .CurrentInputLanguage
(only if input language installed)
InputLanguage.CurrentInputLanguage = InputLanguage.FromCulture(New CultureInfo("ru-RU"))
Using property .CurrentCulture
(only if input language installed)
Dim culture = System.Globalization.CultureInfo.GetCultureInfo("ru-RU") Dim lang = InputLanguage.FromCulture(culture) If InputLanguage.InstalledInputLanguages.IndexOf(lang) >= 0 Then InputLanguage.CurrentInputLanguage = InputLanguage.InstalledInputLanguages(InputLanguage.InstalledInputLanguages.IndexOf(lang)) System.Threading.Thread.CurrentThread.CurrentCulture = culture End If
Using winapi function .LoadKeyboardLayout
(slowly, works even if input language not installed)
<DllImport("user32.dll")> Private Shared Function LoadKeyboardLayout(ByVal pwszKLID As String, ByVal Flags As UInteger) As IntPtr End Function LoadKeyboardLayout("00000419", 1)
Additional
For check current culture:
InputLanguage.CurrentInputLanguage.Culture.Name
Check is input language installed:
InputLanguage.InstalledInputLanguages.IndexOf(InputLanguage.FromCulture(New CultureInfo("ru-RU"))
Switch to next locale identifier (keyboard layout):
Declare Function ActivateKeyboardLayout Lib "user32" (ByVal HKL As Integer, ByVal flags As Integer) As Integer
'switch keyboard layout to next
Sub SwitchKeyboardLayout()
Dim HKL_NEXT As Integer = 1
Dim dl As Integer = ActivateKeyboardLayout(HKL_NEXT, 0)
If dl = 0 Then MsgBox("Unsuccessful!")
End Sub
