Web addin dialog box in powerpoint: centering and inserting web browser emulation

votes

Operation system: Windows 10

MS Office version: 2019 64-bit

I am trying to create an MS Office web add-in which allows me to place different html pages to different slides. While reading different parts of the MS documentation and web-searching, I could not understand how to:

  1. Center the so-called Taskpane in the center of a slide after start
  2. Insert a web object with an option to show some website content (including js) WITHOUT errors connected to MS Office safety

A good example is a Plotly D3.JS Charts. I try to do practically the same but with support of loading local html files.

enter image description here

UPD: I know about LiveWeb, LiveSlides and other solutions. However, they have their own security problems - I have to correct regit. Therefore, please, do not propose them.

The CustomTaskPane object is intended for controls with which the user interacts, similar to the Format Object task pane. You wouldn't normally place this in the center of a slide. Have you looked at Shyam Pillai's LiveWeb add-in? It seems to already do what you're trying to program. skp.mvps.org/liveweb.htm – John Korchok
@JohnKorchok, no, there is a strong point to put it into the center. I saw the LiveWeb add-in. There is a problem with it - the security error. Moreover, it is a VSTO add-in, not Office.js one. Plotly D3.JS does not have this problem. – Alex

The task pane in an Office Web Add-in always opens to the side of the Office application window. You cannot configure it to open in the center of the document. Also, you cannot have separate task panes for each slide.
