npp_sendmsg not working

[jairocontreras]

npp_sendmsg NPPM_GETNBOPENFILES 0 0
echo $(MSG_RESULT)

the output is blank!

This is unexpected, it works for me.
Could you run

npe_debug 1
npp_sendmsg NPPM_GETNBOPENFILES 0 0

and tell what you see in the output starting from the line ; executing: NPP_SENDMSG NPPM_GETNBOPENFILES 0 0 ?
For example, for me it is:

; executing: NPP_SENDMSG NPPM_GETNBOPENFILES 0 0
NPP_SENDMSG: NPPM_GETNBOPENFILES 0 0
; uMsg parameter...
CheckCmdArgs()
{
   [in]  "NPPM_GETNBOPENFILES"
   [out] "NPPM_GETNBOPENFILES"
}
; wParam parameter...
CheckCmdArgs()
{
   [in]  "0"
   [out] "0"
}
; lParam parameter...
CheckCmdArgs()
{
   [in]  "0"
   [out] "0"
}
; uMsg  = 2031 (0x7EF)
; wType = int,  wParam = "0"
; lType = int,  lParam = "0"
; calling SendMessage ...
; ... SendMessage has been called

And running a single command set shows:

SET
local $(LAST_CMD_RESULT) = 1
local $(MSG_LPARAM) = 
local $(MSG_RESULT) = 14
local $(MSG_WPARAM) =

From what I see on the screenshot, it looks like the first command npe_debug 1 had not been executed at all!
I have two questions:

1. How are you running these commands? (For example, directly from NppExec's Console, or from NppExec's Execute window, or somehow else)?
2. Could you additionally run the following commands

echo 1
echo 2
echo 3

and paste the output here?

[jairocontreras]

thank you! i figured it out. i need to execute one command at a time. i'm getting one extra tab count though whether i use the console or execute window

[Vitaliy Dovgan]

The +1 tab corresponds to an invisible "new 1" tab in the Secondary View.
You can check:

npp_sendmsg NPPM_GETNBOPENFILES 0 PRIMARY_VIEW
echo $(MSG_RESULT)  // possible output: 3

npp_sendmsg NPPM_GETNBOPENFILES 0 SECOND_VIEW
echo $(MSG_RESULT)  // possible output: 1

npp_sendmsg NPPM_GETNBOPENFILES 0 0
echo $(MSG_RESULT)  // possible output: 4 = 3 + 1

oh ok so even if i haven't opened a file in Other View it's still counted. that's not right 😕 not sure if that's a feature of this plugin or the app itself

[Vitaliy Dovgan]

This is the feature of Notepad++ itself.
NPP_SENDMSG simply invokes Win API function SendMessage.
