<![CDATA[.NET Plugin: Dockable Dialog freezes Notepad++]]>Hi,

I came across a show-stopping issue with dockable-dialogs written in .NET. It is fairly easy to reproduce:

  1. Create a new Plugin-Project in Visual Studio using the .NET plugin template
  2. Place a GroupBox (or any other container control) on the “frmMyDlg” form
  3. Place a button inside the GroupBox (so the button becomes a child of the groupbox)
  4. Compile the plugin
  5. In Notepad++, UNDOCK the dialog (dialog must be floating)
  6. Click the button
  7. Use the mouse to move the dialog window -> Notepad++ freezes

It only happens when the button is a child of a container control. When the button is a direct child of the form, it works. There is also no problem as long as the dialog is docked.

Any ideas?
Thanks
Dirk

http://docs.notepad-plus-plus.org/index.php?title=Plugin_Central
and under Plugins at https://notepad-plus-plus.org/resources.html
, but a hint at https://notepad-plus-plus.org/contribute/plugin-howto.html makes sense.

Also some other links are a little bit outdated, but I’m not sure how to contribute to the webpage.

Im missing that link on https://notepad-plus-plus.org/contribute/plugin-howto.html there is no information about needing to register. Anyway I just tried creating an account now…

There are some real wizards in here like @dail and others. Perhaps they can be of assistance?

Could you elaborate on cleaning of the Scintilla and Notepad++ interfaces?
Did you register for an account on the Notepad++ Plugins Repository to get your plugins listed?

I have spent two days trying to fix this problem, but I was not successful. I created a regular C++ plugin and hosted my .NET form in there (as C++ can work as a bridge between native and managed code). The behaviour is similar: As long as the dialog is docked it works but as soon as it’s undocked N++ freezes.

I also tried to create a new Thread for the dialog and then use Application.Run(mydialog) so the dialog has it’s own message-pump. That didn’t help either.

I’m giving up, I can’t affort to spent more time on this.
Regards
Dirk

Thanks for the report. As of yet, my work has predominately been making the interface to N++ smoother from C#. I have yet do dig into the details. However, I have to a large extend been discouraged by the fact that neither the author of Scintilla nor the author of N++ seem to have an interest in cleaning up their interfaces.

Nor has the author of N++ wanted to link my C# project to the N++ homepage, and my plugins are not to be found in the plugin manager. In many respects its very easy to get discouraged in the N++ community.

It also happens with the “old” v0.60 plugin.

using the .NET plugin template

Which template exactly? There are a few different versions of it floating around, some of them being pretty old. The most recent and currently maintained is located here.
