Strange behavior of SendKeyEvent

[RedOctober]

Hello,

please take a look to a code below:

Code: Select all

var
    key_event: tcefkeyevent;
    str: widestring;
    q: integer;    
begin    
    str:='super.login_myusername';
    
    key_event.focus_on_editable_field := 1;
    key_event.modifiers := GetCefKeyboardModifiers(ord(str[q]), 0000000);
    for q := 1 to length(str) do

    begin
      FillChar(key_event, SizeOf(tcefkeyevent), 0);
      key_event.kind := KEYEVENT_KEYDOWN;
      key_event.character := str[q];
      key_event.windows_key_code := ord(str[q]);
      key_event.native_key_code := 0000000;
      action_browser.browser.Host.SendKeyEvent(@key_event);

      FillChar(key_event, SizeOf(tcefkeyevent), 0);
      key_event.kind := KEYEVENT_CHAR;
      key_event.character := str[q];
      key_event.windows_key_code := ord(str[q]);
      key_event.native_key_code := 0000000;
      action_browser.browser.Host.SendKeyEvent(@key_event);

      FillChar(key_event, SizeOf(tcefkeyevent), 0);
      key_event.kind := KEYEVENT_KEYUP;
      key_event.character := str[q];
      key_event.windows_key_code := ord(str[q]);
      key_event.native_key_code := 0000000;
      action_browser.browser.Host.SendKeyEvent(@key_event);
    end;
end;

In general it works pretty fine, but:
1. Completely ignore a dot char (.) and few more chars like #$%^&*( , but send fine a chars like ! and @, for example.
2. When the char "y" occurs in string, it hangs: I have to click to the field manually, then it continues to send the rest keys after "y".

What am I doing wrong? Thanks in advance for answers!

Hi,

I typed all those characters using the SimpleOSRBrowser demo in google.com and it works fine.

Please, try the SimpleOSRBrowser demo with those characters. If it works in your computer then I would add some code to the AppEventsMessage procedure in that demo to log the complete sequence of messages and all the TCefKeyEvent fields. You can use that log to send the same sequence of messages whenever you like.

There are some differences filling the TCefKeyEvent fields between that code and the AppEventsMessage procedure in SimpleOSRBrowser. key_event.character, key_event.windows_key_code and key_event.native_key_code have different values in the demo.
