Hi all.

How can I make EditorGadget always set to English only ?
It is clear that you can find out the system key combination for changing the language and wait for this event, but... As we know... there are several ways to change the input language. For example, from the system tray or... even programmatically. So how can we make it easier ? Check the language using a timer ? We know that Windows assigns a default input language to each window. But I read somewhere that the operating system also remembers the current input language for each window.

Thanks in advance.

Hi ZX80
I am using the next code to switch between LTR and RTL languages
Adapt it for your needs

Code: Select all

tmp = GetWindowThreadProcessId_(GetForegroundWindow_(),0)
  tmp = GetKeyboardLayout_( tmp)
  If tmp >> 16 = 1025
    .....
  EndIf
  
  languageflag = 0
  kbd$ = Space(8)
  For i = 1 To 10
    ActivateKeyboardLayout_(#HKL_NEXT	,0)
    GetKeyboardLayoutName_(@kbd$)
    If kbd$ = "00000409"
      Break 
    EndIf
  Next

RASHAD
AZJIO

thank you both !

I couldn't come up with anything smarter than the code below. But first I would like to take this opportunity to thank RASHAD for his many well-written and concise code snippets on this forum. I couldn't have done it without your bricks. Thanks a lot !
On my system the keyboard layout changes after pressing the following key combination: LAlt & LShift.
So... To make the code a little bit more generic... The next question arises:
How can I programmatically determine the key combination for changing the keyboard layout ? I clearly understand that it may differ on different computers. And then this code will no longer work.
If anyone has time, please test the code. If you find an error, please let me know. If you know a better way to solve this problem, please share. To be honest, I was hesitant before using the low-level hook. This may be excessive. But I repeat... I don't know any other way. That's how I see it:

Thank you in advance for your attention.

P.S. There is probably a system event for changing the language that I just don't know about. This is what I need to catch, not set the hook. It should be simpler and more versatile.

Hi ZX80

You want to detect when the language has been changed at any time while your snippet is running
No need to Low Level Hook
I myself use Ctrl+0 and Ctrl+1 to change between Arabic and English
But say the user may use something else
It doesn't matter
Next snippet will do what you want
Check and report

There seem to be two ways to do it. A very complicated way, and a simple way.

Good time, all !

Thank you very much for your participation !

RASHAD, I understand what you mean, but I'm a little confused by the timer that runs all the time and is set for such a short time. Overheads ? Yes, your code is more universal and does not require additional configuration for the system key combination to change the layout. Thank you !

AZJIO, thanks for your code. Your procedure for checking Latin will be very useful.

breeze4me, you're rock ! Right on target ! This is what I was looking for ! I like your first code ! Interfaces are complicated, but very cool ! Today you won !

I think I have already received comprehensive answers here and the topic can be closed.
Thank you very much !
