i have developed an ios application (not finished), and know i would like to migrate my project to use core Data, it's this possible ? if yes How ?
without giving any specifics it is difficult to be specific in an answer.
What you need to do is to link to the binary of the CoreData Framework in your solution.
You need to decide which storage you wish to use (sqlite etc). Is the information to be persisted user preferences? Is is a mini database? Is is one flat file store?
At the end of the day you'll need to do some reading based on which of the types of backing store you choose.
Hope this helps as a starting point.

Is there a way to take a screenshot in UE4 while in-game and save it somewhere so that I can use it again as an image or something?
There is a HighResShot solution, but that saves it somewhere outside the range of the editor (you cannot reach it programmatically), is there another way of doing it, that allows me to access it in-game?
I would recommend using HighResShot for taking the screenshots. As you mention, it saves this outside the range of the engine, in the "saved" folder. (In packaged builds, the saved content is in the user's appdata.) You can actually get this with ProjectSavedDir(), which returns this saved directory. https://docs.unrealengine.com/en-US/API/Runtime/Core/Misc/FPaths/index.html
It's C++, but you can expose this to Blueprints fairly easily. You can get the ProjectSavedDir()/Screenshots directory and load the images in-game. For doing this, I recommend the Ramas plugin (https://forums.unrealengine.com/development-discussion/blueprint-visual-scripting/4014-39-rama-s-extra-blueprint-nodes-for-you-as-a-plugin-no-c-required?3851-(39)-Rama-s-Extra-Blueprint-Nodes-for-You-as-a-Plugin-No-C-Required=)

Im wondering for what the SQL database project template exists. I have created one and inserted a table with some col. Now i saved that, so i want to write Into that mdf-file Form a Windows forms project. I dont know how to acces that or even if this SQL project template is ment for that sort of usage. Is this a good solution for a local database?
Sry for that kind or basic question
The database project exists so that you can store the database structure in source control, generate and deploy the database (or upgrade scripts).

I am pretty new to CoreData Programming but would like to ask:
Do I need to create a database to use CoreData ? Can coredata operate on a simple flat file ?
Please provide suitable references & links.
Thanks in advance
Core Data provides four native types of persistent store:
SQLite
Binary
XML
In-Memory
These store types each offer different benefits and tradeoffs, and are described in “Persistent Store Features”. The Binary and XML stores are "atomic” stores—they must be read and written in their entirety, unlike the SQLite store which can be modified piecemeal, one record at a time if you wish.
Refer to the first link (pdf)

In my app which is data collection app i need offline support. Let's say when i am gathering user's data there is no connection on device but once the device comes in network the whole data should automatically goes to the server.
How should i implement this kind of functionality.
Thanks,
Your question is pretty vague, but I assume you're wondering HOW to persist data and not how to automatically send it to the server.
If the data is very simple, NSUserDefaults may suffice.
If you need a bit more complicated data structures, you can use archives.
If you need to store complex object graphs you need to use Core Data.
There's a pretty good guide explaining all of these here.

How can integrate particular Third party tool with my vb.net application
Using Interop you can do Call Shell("tool.exe")
More details are definitely required, if you're still interested, but roughly speaking it depends on whether by 'integrate' you mean just triggering another application from yours or do you actually require back 'n' forth communication between these apps, whatever they are.
I can't remember the VB.NET specifics and I don't have it available right now, but in C# you could simply trigger another application like this:
using System.Diagnostics;
Process.Start("<shell command, e.g. fred.exe>");
