Scratch

So I could open up the exe file, and run it from my C# App? Could you go further in detail? Thanks

Maybe I didn't fully understand your question. Could you please be a little more specific what exactly it is you would like to do ....

Scratch is an interpreted language with a dynamic IDE, i.e. you can change components and scripts while an application (in Scratch it's called 'project') is being executed and see the results right away.

Scratch is not really a dynamic programming language IMO, because you cannot create any new objects in 'presentation mode' or when a project is being run in a web-browser. It's object-based in a way, however without the notion of classes (there are only instances of "Sprite", "Stage" - a Singleton -, and - arguably - "Variable" in Scratch, which can be directly manipulated with command blocks and IDE-controls).

The Scratch "language" itself is the command blocks. This is really something I found interesting when I looked at the Source Code. The Blocks aren't just a UI-model for some other underlying semantics-enginge (as I had imagined), but the language itself. Therefore you cannot "file out" the source code of a Scratch project (except for a pseudo-code like summary which however cannot be filed back into Scratch again).

There is no official way to "translate" a Scratch project into another programming language. I do believe, however, that it wouldn't really be too hard to create a native compiler for Scratch, or even a Scratch-to-something-else-like-C converter. If you want to give it a shot, go ahead! The Squeak Source Code of Scratch isn't all that hard to understand.

My fake compiler, however, is really just producing a kind of self-extracting zip-file containing a slightly altered version of the complete Scratch environment together with an individual Scratch project. Of couse you can call the exe-file like any other windows executable from within other programs, but you can't change the way it works using Visual Studio C#, if that's what you're asking.

Basically my idea is when the user presses a button one of my scratch videos pops up either in a new window, or in something like a web browser control in my application. I am just wondering how to do this.

When you say "video" do you mean that there is no need for the user to do anything; just watch it?  If that is the case, you could use screen capture software to convert it to a video format.
