<![CDATA[How to capture what user is typing]]>Hi,
I am trying to write a plugin which need to capture all what user is typing on the notepad++, even when it is set as “read-only”, so I was considering by filtering the “WM_KEYDOWN” message. but I did not receive these message in messageProc function.
Can someone give some advice? Thanks.
Regards,
Bill

I’m not saying it is impossible though, just don’t know how.

I was trying to intercept the user typing by receiving the notification when editor is read-only, so far, it works good. but read-only editor is not an ultimate solution, I wondering is there any way to ignore the key press on the editor and interact with the key pressing?
Regards,

Edit: Actually it doesn’t require a hotkey, however the struct is the only way to register functions with Notepad++…which automatically show up in the menu.

the BACKSPACE will trigger the notification with SC_MOD_DELETETEXT bit in the modificationType. Thanks.

I got another question.
Currently I bind the hotkey with the function using the menu. But is it possible to hide the menu or is there any another to link the hotkey and func?

The modificationType will have the SC_MOD_DELETETEXT flag set.

If you are needing to capture actual keyboard input and not just changes to the text document then you’ll have to go the subclassing/superclassing route.

SCN_MODIFIED does not use the ch field, it uses the text field because the user could paste multiple characters (or delete a range of text).

If indeed you do want individual characters only (and skip any paste/deletes) then you can catch SCN_CHARADDED notifications which does use ch.

I already got notified. but the notifyCode->ch is always equals to 0

Can you please help to explain how can I check what user is typed?

That being said you won’t receive WM_KEYDOWN notifications. Those are handled by Notepad++/Scintilla. What you normally do is catch notifications from Scintilla that tells you the user has added (or removed) text by catching the SCN_MODIFIED notification which has the info you need (e.g. position, text). You can also catch SCN_MODIFYATTEMPTRO which tells you a read-only document was attempted to be modified…but I don’t believe this notification tells you what was actually attempted.

If indeed you are actually needing the raw WM_KEYDOWN notifications there are ways of subclassing (superclassing?) the Notepad++ window and catching them before Notepad++ does…but that is beyond by Win32 API knowledge, but I do know some plugins do that.
