Hi.
Looking for a way to intervene between the TranslateMessage function and Window function for a TextBox. Want to catch the character for control and if not accepted discard the character.
I do not want to bypass the TranslateMessage function.

Thanks for any help

Is this WPF ? WinForms ? ... or ?

What Events of the TextBox Control do you handle now, and what is the relationship of the TextBox to the "TranslateMessage" function ?

This is not related to TranslateMessage or its bypassing. All TextBox controls have a mechanism for cancellation, just find it.
When you say "TextBox", the question is: which one? Full type name, please.
You really need to tag the UI library/framework or application type your are using, when UI is involved.

It´s unsafe direct against win api. Catching keybord low level event, it translates key kodes beföre the textbox get a caracter posted.

What is unsafe and why? TranslateMessage is unsafe, because it goes beyond .NET and requires P/Invoke. Handling KeyPress is the standard .NET way. Do you need any help with that? Please explain your goal or desired behavior.
