I thought I would ask this in the lounge as I asked a few questions in the specific forums but it seems like I need more general advice and less specific advice.
Anyway, here goes:
I have an application that works quite well in Qt 5.4 that I would like to port a part of it in Microsoft Office based applications.
So, essentially the idea is this:
1. I open Microsoft Word or PowerPoint and a custom tool-bar that I created is shown up top.
2. I click on an "add" button and a component of some kind which represents the Qt 5.4 application I already created is added unto the page.
3. I can also add properties to the Qt 5.4 "COM" object I added so that when the Word or PowerPoint file is saved the properties are saved "in" the document/presentation and when said document/presentation is opened the properties are loaded along with the aforementioned "COM" add-in and everything auto-magically loads, etc.
Ideally, I would like to reuse the QT code I created already. I successfully compiled an ActiveQT based project but I get the following error when I try and add the resultant file into an Microsoft Word of PowerPoint file:
The selected file does not contain any self-registering ActiveX controls.
There are examples of creating ActiveX controls using MFC/ATL but I'd like to avoid it simply because I have already written a substantial portion of the code-base in Qt.
However, I am open to ALL suggestions on how I can achieve the above goals.
