How to write a plugin?

I wrote the Delphi plug-in template.  Here's an example of a plug-in

This hides all unmarked lines.  All you do is add this to the template in place of the existing MyProc1.  The code is more or less identical to the C examples that are given on the Notepad++ website.  You'll need the Scintilla documentation, specifically scintilla.iface.  This tells you what the SCI_xx commands do.

procedure MyProc1; cdecl;
var
   currentEdit : integer;
   LineCount : integer;
   LineNo : integer;
   Mask : integer;
   LastMarker : integer;
begin
   SendMessage(LocalNppData._nppHandle, WM_GETCURRENTSCINTILLA, 0, integer(@currentEdit));
   LineCount := SendMessage(getCurrentHScintilla(currentEdit), SCI_GetLineCount, 0, 0);
   LastMarker := 0;
   for LineNo := 0 to LineCount - 1 do begin
      Mask:= SendMessage(getCurrentHScintilla(currentEdit), SCI_MarkerGet, LineNo, 0);
      if Mask <> 0 then begin
         if LastMarker <= LineNo-1 then begin
            SendMessage(getCurrentHScintilla(currentEdit), SCI_HideLines, LastMarker, LineNo-1);
         end;
         LastMarker := LineNo+1;        // Start hiding from LineNo+1
      end;
   end;
   //
   // Hide from the last marked line up to the end (providing there's something to hide)
   //
   if LastMarker <= LineCount-1 then begin
      SendMessage(getCurrentHScintilla(currentEdit), SCI_HideLines, LastMarker, LineCount-1);
   end;
end;

Hi,
I want to create a plugin for Notepad++. I made a DLL acc. "NppInsertPlugin" and "PluginDemo" I found on the net. I compiled it in Borland C++ Builder. When I copy dhe library into plugin directory of N++ and start N++, the application fails down (ver. 4.1.2 and 4.2.2 of N++), or there is a warning "The specified procedure could not be found" and N++ is not running (ver. 3.9, fails without debug window).

Seems to be a problem with compatibility (different format). I would like not to use MS VC++ compiler.

I tried to compile "NppInsertPlugin" with MinGW but the compilation failed.

Could anybody points the source that can be used for Borland Builder or other compilers (except VC++) with correct makefile or batch file (it can do "nothing special", I would like to verify that anything is possible with Borland, gcc, ...).
Or information how to check my DLL (from external program I can run e.g. "getName" function, also compiled with Borland Builder).

I had also function: "messageProc".

Hello Kristian,

I asked a similar question here: https://sourceforge.net/forum/forum.php?thread_id=1798333&forum_id=482781.  I haven't received an answer yet, but I found a plugin HOWTO here: http://notepad-plus.sourceforge.net/uk/plugins-HOWTO.php.  I have been programming in C++ for quite a while, but I've never written a DLL and wanted to create a Notepad++ plugin to help me learn to write DLLs.  It looks like I will just have to learn the ins and outs of Notepad++ before I am able to do that.  It would be nice if there was better documentation for the plugin framework.

And is it possible to use Delphi to create a plugin DLL? there is a template, yet there is no how to documentation
