I need make a powerpoint slider from uploaded file and display it in web browser, using ASP.Net. I want tool to make it without 3rd party library and I have tried Office Web App like this
<iframe id="previewer" style="width:100%;height:811px;"
src="https://view.officeapps.live.com/op/view.aspx?
src=https://img.labnol.org/di/PowerPoint.ppt
">
</iframe>
But I don't want allow the client to make download for the file or cloning it.
I have done something similar but using AngularJS.
First convert ppt/pptx to pdf's as they are uploaded to server (you will need Powerpoint Interop library - SaveAs method)
Use pdf.js on the html side to display pdf
You can also use a carousel control to help select each individual page on the pdf.
Reason you need to convert to pdf - ppt/pptx is not a browser view-able format

I have created a HTML project. But my main aim is to display the pdf's on my site so that users can't save or download them is this possible using (https://mozilla.github.io/pdf.js/) viewer? If so how can i do it because i'm trying to output a lot of pdfs and this just seems impossible to do looking at the code.
No, it's not possible to display native pdfs to the user without allowing them to download them. By the nature of http, they will have had to download the pdf data in order for them to be displayed.
However, you could take snapshots of the pdf on the server, and display these to the user as pngs.
There are a number of libraries that will allow you to convert the first page of a pdf to an image, I suggest you start by trying to implement one of those.

I think you'd need a custom PDF viewer in your app, like what Google Drive does with images and documents.
I'm not aware of any functionality that allows an app to tell Chrome/Firefox or the registered PDF handler to limit user interaction like you mention.
I it possible to run javascript code on for example: mydomain.com/pdf/pdf-example.pdf?

You can use pdf.js to render a PDF file onto a standard HTML page. So instead of linking directly to the PDF file, you would create a new HTML page, where you would embed the pdf.js viewer, as well as any additional custom Javascript. Here is a demo. The downside to pdf.js, is browser support is limited.
Another option is pdfobject, which enables you to embed PDF's within pages. This uses the browsers native PDF viewer for rendering.

Since you are delivering pdf file directly into the browser, displayed using Adobe Reader ActiveX, how can it be possible to prevent file download, since the files are displayed after downloaded into your temp directory?
So it is not possible using ANY JavaScript library.
The only way to secure your master PDF files is by creating Images for each page and present those to the user on the web via your own interface (html, flash etc).
You may use ImageMagick along with GhostScript for this.
