How can I simulate Alt+Shift to change the language in Windows (II part)?

Question

The problem (switching language dynamically) is solved with ActivateKeyboardLayout, but it still remains when i dynamically create a component on the form ( for ex. TEdit ). When this component gets into focus, the language changes to default. I tried use again ActivateKeyboardLayout, after creating the components, but it did not worked. Any ideas ?

@TOndrej: I used it like this: LoadKeyboardLayout(someId, KLF_ACTIVATE) — dzibul, Mar 10 '11 at 09:19
Cannot duplicate, my dynamically created Edit preserves the changed layout. Can you post a sample that have the problem? — Sertac Akyuz, Mar 10 '11 at 17:47
@Sertac Akyuz: I have a dbgrid on the form. When I create the Edit dynamically I set the parent to dbgrid. The initial call of LoadKeyboardLayout is onActivate. — dzibul, Mar 10 '11 at 18:42
I think your problem is related with a known problem. See the QC report #79485: [Keyboard layout swtching when exiting dbgrid control](http://qc.embarcadero.com/wc/qcmain.aspx?d=79485). And see [this thread](https://forums.embarcadero.com/thread.jspa?messageID=180475&tstart=0#180475) on embarcadero forums for a workaround. — Sertac Akyuz, Mar 10 '11 at 20:10

Your problem may be similar to this question.

Otherwise this code does it:

keybd_event(VK_MENU, 0, 0, 0);
keybd_event(VK_SHIFT, 0, 0, 0);
keybd_event(VK_MENU, 0, KEYEVENTF_KEYUP, 0 );
keybd_event(VK_SHIFT, 0, KEYEVENTF_KEYUP, 0);

This code switches to next input language (and only if the default shortcuts have not been changed). It won't help if you have more than two input languages – Sertac Akyuz Apr 25 '12 at 14:31

at first you have to use "Windows" then you can use this method: ActivateKeyboardLayout(EnglishLayoutHandle, KLF_ACTIVATE) you can change "EnglishLayoutHandle" for any lang you want

On the Console application use

HWND handle = GetForegroundWindow();
PostMessage(handle, WM_INPUTLANGCHANGEREQUEST,
            0, (LPARAM)HKL_NEXT);
