SendMessage with SciTE?

[Dolemite50]

Hello,

I am trying to send Scintilla key commands to SciTE but not having any luck. I have the SciLexer.dll in the scriptDir and think I have tried every combination:

#include <SendMessage.au3>
Opt("WinSearchChildren", 1)
Opt("WinTitleMatchMode", 4)
$hScite = WinGetHandle("classname=SciTEWindow")
$hSciteDirector = WinGetHandle("DirectorExtension")
Global Const $SCI_GETLINE=2153

Attempts -->

$sRet= _SendMessage($hScite, $SCI_GETLINE, 0, 0, 0)
$sRet= _SendMessage($hScite, $SCI_GETLINE)
$sRet= _SendMessage($hScite, 2153, 0, 0, 0)
$sRet= _SendMessage($hScite, 2153)

$sRet= _SendMessage($hSciteDirector, $SCI_GETLINE, 0, 0, 0)
$sRet= _SendMessage($hSciteDirector, $SCI_GETLINE)
$sRet= _SendMessage($hSciteDirector, 2153, 0, 0, 0)
$sRet= _SendMessage($$SciteDirector, 2153)

$sRet= _SendMessageA($hScite, $SCI_GETLINE, 0, 0, 0)
$sRet= _SendMessageA($hScite, $SCI_GETLINE)
$sRet= _SendMessageA($hScite, 2153, 0, 0, 0)
$sRet= _SendMessageA($hScite, 2153)

$sRet= _SendMessageA($hSciteDirector, $SCI_GETLINE, 0, 0, 0)
$sRet= _SendMessageA($hSciteDirector, $SCI_GETLINE)
$sRet= _SendMessageA($hSciteDirector, 2153, 0, 0, 0)
$sRet= _SendMessageA($hSciteDirector, 2153)

ConsoleWrite($sRet & @CRLF); --Returns 0 for all attempts

When I set the return value to 1 or 2 it returns the handles and msg fine but I've been unable to get any code to work.

I've checked into _SciLexer.au3 and it's pretty slick but I could only get the commands to work on the user-created editor.

I tried to break down it's functions and recreate the DllCalls they are using with the same combinations but still no love. I assume that my problem is with the hwnd variable I am using because it looks like the _SciLexer UDF is using the return from a createWinEx func rather than scite's hwnd. I got desperate and attempted the same:

Local $wp = 0, $lp = 0
Global $user32 = DllOpen("user32.dll")
Global $SciDLL = DllOpen("SciLexer.dll"); ALSO --> Global $SciDLL = DllOpen(@ScriptDir & "\SciLexer.dll")

; (swapping $hScite and $hSciteDirector):
$ret = DllCall($user32, "long", "GetWindowLong", "hwnd", $hSciteDirector, "int", -6)
$sRet1= DllCall($SciDLL, "long", "SendMessage", "long", $ret[0], "int", $SCI_GETLINE, "int", $wp, "int", $lp)
$sRet2= _SendMessage($ret[0], $SCI_GETLINE)
$sRet3= _SendMessageA($ret[0], $SCI_GETLINE)

ConsoleWrite($ret[0] & @CRLF); --> 4194304
ConsoleWrite($ret[1] & @CRLF); --> 0x01B40134

ConsoleWrite($sRet1 & @CRLF); --> 0
ConsoleWrite($sRet2 & @CRLF); --> 0
ConsoleWrite($sRet3 & @CRLF); --> 0

DllClose("user32.dll")
DllClose("SciLexer.dll")
DllClose(@ScriptDir & "\SciLexer.dll")
...

I'd show a few more desperate attempts but I'm probably about to run the server out of ink.

Any help?

Thanks a lot!

I'm at a loss, any help would be much appreciated.

You can only send messages to the control it self, not just to the entire window.

$hScite = WinGetHandle("classname=SciTEWindow")

Returns the handle to the whole window.

Also, opening the scilexer.dll and doing nothing with it, doesnt matter.

btw, you dont have to open the dll, because your window doesn't own the control.

Hello,

I am trying to send Scintilla key commands to SciTE but not having any luck. I have the SciLexer.dll in the scriptDir and think I have tried every combination:

I assume you have SciTE open with a text file you want to get information from. The first thing is to get the handle to the editor something like this

opt("WinTitleMatchMode",2)
$hScite = ControlGetHandle("SciTE [","","[CLASS:Scintilla;INSTANCE:1]");

Then if you want to get the text of a particular line you have a problem. You can find the length of a line by sending a message. I don't see how you can get the line the way you might think you could. To get the text of a line there is a message $SCI_GETLINE, which you know, but you have to pass it the line number (first is 0) and the address of a buffer where it can write the result. If the editor is part of your program this is not a problem, but since it isn't (if I understand what you are trying to do) then the program which has the editor cannot write to the memory owned by your program. If you are communicating with Scite then I suggest you read the SciTE-LUA interface i n SciTE help. I had a quick look and it would seem that to get the text of a line the process would be to mark the line as selected then send a message to copy that text to the clipboard and then you can get that text.

If I'm off track just tell me, or if what I say is wrong I'm sure someone will tell me, and if I don't make sense then let me know that as well

Thanks guys!

I'm sorry that it's taken me awhile to get back to this post. I think I see what I need to do now, target the control instead of the sciteHnd or Director's.

I'm looking forward to trying it out and I'll let you know how it goes.

Thanks again!

Something to play with: ( You need scilexer.au3 )

; NOTICE: I haver placed the following line in SciLexer.au3 to make it 
; behave with the latest stable version of AutoIt:=
; #include <WindowsConstants.au3> ;Failed on latest release (3.3.0,0) without it 

#include <SendMessage.au3>
#include <_SciLexer.au3>
_Main()
func dbg($msg, $erl=@ScriptLineNumber, $error=@error, $extended=@extended)
    ConsoleWrite('(' & $erl & ') (' & $error & '(' & $extended & ')' & $msg & @CRLF)
EndFunc
Func _Main()
    Opt("WinTitleMatchMode", 4)
    $hwndctl = ControlGetHandle("[CLASS:SciTEWindow]", "", "Scintilla1")
    If not $hwndctl <> 0 then dbg("ERROR: $hwndctl:=" & $hwndctl)   
    dbg("Sci_VisibleLines():=" & Sci_VisibleLines($hwndctl))
    
    ; Getting text accros the process boundary is dangerous and did not work
    ; with this implementation of Sci_getText
    ;dbg("Crashing?")
    ;sleep(2000)
    ;CRASHING dbg("Sci_getText:=" & @crlf & Sci_getText($hwndctl))
    
    dbg("Sci_GetLenght():=" & Sci_GetLenght($hwndctl))
    
EndFunc

My output when testing against a scite window with the sample code:

>Running:(3.3.0.0):C:\Program Files\AutoIt3\autoit3.exe "G:\tools\autoit\udfs\Test-scintilla.au3"

here are the implementaions of GetText / SetText to use accross process boundaries:

It's easier with ControlSetText / GetText, just look at Jos' post: http://www.autoitscript.com/forum/index.ph...st&p=641310
