VB.NET Dlls - Passing a form as an argument [Resolved]

[Justy]

Hello,

I've finally decided to begin exploring .NET and have begun
experimenting with a little program with a plug-in style architecture.
I have a plug-in dll which uses an interface dll to pass arguments to
a host exe.

I can pass strings and simple types like that, but say for example I
would like to pass a form (from the plug-in dll) as an argument to the
host exe (which isn't aware of the form class type in the plug-in),
and then manipulate the form from within the host exe?

If anyone has any insight, or links to articles or tutorials, that
would be a great help.

Thanks!

Justin.

just pass the form object as an argument of type Windows.Forms.Form

just make sure you make the parameter ByRef too.

Thanks folks,

I'm getting "Option Strict disallows implicit conversions from System.Windows.Forms.Form to PluginSample.Plugin.Form1"

It's very head scratching learning stuff from scratch again... in VB, you'd have declared the argument as type Form and bobs your uncle!

use CType

yourForm1 = Ctype(yourForm1Arg, PluginSample.Plugin.Form1)

Simple as that! It's working now...

Thanks a lot.
