VKB: how to switch between text mode and password mode and disable input menu button?

[citapto]

First sorry about my English!!!
I am working with Symbian VKB.
I got example from http://wiki.forum.nokia.com/index.php/How_to_launch_virtual_keyboard_with_touchUI and now I can call and use VKB.
So now I want to switch between text edit mode and secret (passwords) edit mode. I try many time with
CAknEdwinState::SetCurrentInputMode(EAknEditorSecretAlphaInputMode); but it no help!!!

I found that VKB shown secret symbol (*) when set input capabitilites with para TCoeInputCapabilities::ESecretText in function CFEPHandler::InputCapabilities() const but I don't know how to update the capabitities (which object call this function and when???) because this function called only once time when my app started.

2nd question is how to disable input menu button on vkb (like wifi password input screen)?

Thank very much!!!

It is the type of editor you use and its flags that determine the type of input they will receive from the keyboard. So focus on your editor not on the VKB.

Use a CEikSecretEditor

Thank you very much! But I think I need explain more clearly.
My problem is when user input a password not when the password completely inputted.

When user input a char, that char show the true char (ex: 'a', 'b') about 1 second and after that it change to '*'.

And I don't have a true editor to show the password. I just get the password from user and draw it to screen by my code.

So you think my custom control need implement CEikSecretEditor?
Now in Vietnam is 11pm and I will try tomorrow.

And do you have any idea about disable input menu key on VKB (the key beside the -> key)
Thanks.
