Resolved [Solved] My own little program

[Peque]

Hi Forum

I'm started to look at learning C sharp - so quite a newbie for this but had some programming skills way back. Sorry the code is properly not high standard, and surely somethng could be done easier
So starting out with hear your input on how to do this, since I would like to gain more knowledge (and here its including C#) instead of looking out the Window :-(
I did after googling etc - found that information for creating the attached Macroes, to attach to my Ribbon, only where able to do use Microsoft symbols etc

My plan is to reply the active mailItem from Outlook (inbox with marked mail or have opened messages) in HTML - As I do in this Macro example.
But all 3button refers to the same action with different information, read from a text file - The action would be creating a reply to the acive Mailitem in Outlook.
This reply would be the same layout for all 3 with some information - along with a Picture - so That I'll properly creating using stringbuilder later on creating the Body with html.
Since the images are not created from the template, I'm instead thinking

But I cannot seem to find my way on getting the active windows - and create a reply for this - Like this macro does.
I would like to create the reply - but not sending it - But the position could be either Inbox or have the email opened by double click on the mail.
