Now, I am building an application like Russian dictionary. How to program the Russian pronunciation in C #, which library to use? Does the Speech or Speech.lib libraries contain "text to speech" functions for Russian as well as for English? Please Help me solve text russian to speech in C # using library or not?

According to this[^], yes it does. BTW, remove your email address from your signature - that's a sure fire way to get spammed.

Thank you so much. Can you show me how to use the SDK? Currently I'm using C # 2012 but have not installed the SDK in C #? Please show me how to use it.

Hi everybody,
I'm currently developing an application in which I have to drag a video from in a media element into another container (let's say a kind of library). The video must keep playing in the media element and only a copy is "stored" in that library.
All the videos present in the library must be visible in order to eventually be reloaded (through drag and drop) into the media player for vizualization.
Have someone an idea on how this could be achieved?
Best regards,
RV

Hi guys,
Probably a simple task but i'm struggling with it.
I have a list of objects, lets call this a list of Object1. Each Object1 contains a list of another object lets say Object2.
Object2 has 2 properties. 'Name' and 'Value'.
I want to be able to select Object1 where Object2.Name equals a specified value using lambda.
eg
class Object2
{
public string Name {get; set;}
public string Value {get; set;}
}
class Object1
{
public List<Object2> theList = new List<Object2>(){ new Object2(){Name = "Blah", Value = "Blah"}};
}
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
var myList = Object1.Where(m => m.theList.Name == "Blah")
}
}
I hope I explained myself clearly.
Many thanks for your help

There are a lot of things wrong with that!
Object1 is a class, not a collection, so you can;t use Where on it.
Name is not a property of the list, it;'s a property of teh objects teh list contains.
Try this:
List<Object1> myList = new List<Object1>();
myList.Add(new Object1());
myList.Add(new Object1());
myList.Add(new Object1());
IEnumerable<Object1> myResults = myList.Where(m => m.theList.FirstOrDefault(o => o.Name == "Blah") != null);

Thanks Member 12616185,
Yes, Object1 was meant to be a collection of Object1's. My bad for not proof reading. Thanks for spotting and correcting.
Your reply worked a treat. Here's the implementation I used which served my purpose.
var myResults = Object1.Where(m => m.Object2.Select(o => o.Value == "802.11g") != null);
Many thanks again for the help

That's not going to do what you want. It's just going to return every item from the input sequence, since m.Object2.Select(...) returns an IEnumerable<T> which is never equal to null.
Try:
var myResults = Object1.Where(m => m.Object2.Any(o => o.Value == "802.11g"));

I did a test run and you were right! all objects came back in the collection.
I have since implemented your recommendation and that worked
Here's my test code for ref.
using System.Collections.Generic;
using System.Linq;
namespace ConsoleApp3
{
class Program
{
static void Main(string[] args)
{
List<Object1> origCollection = new List<Object1>()
{
new Object1() {ID = 1, theList = new List<Object2>()
{
new Object2() { Name = "Mode", Value = "802.11b" },
new Object2() { Name = "BW", Value = "20" },
new Object2() { Name = "Chan", Value = "1" },
new Object2() { Name = "Tech", Value = "SISO" }
}
},
new Object1() { ID = 2, theList = new List<Object2>()
{
new Object2(){ Name = "Mode", Value = "802.11g" },
new Object2(){ Name = "BW", Value = "20" },
new Object2(){ Name = "Chan", Value = "1" },
new Object2(){ Name = "Tech", Value = "SISO" }
}
}
};
var theCollection0 = origCollection.Where(m => m.theList.Select(n => n.Value == "802.11b") != null);
var theCollection1 = origCollection.Where(m => m.theList.Any(n => n.Value == "802.11b"));
var theCollection3 = origCollection.Where(m => m.theList.Any(n => n.Value == "802.11z"));
}
};
class Object1
{
public int ID { get; set; }
public List<Object2> theList;
}
class Object2
{
public string Name { get; set; }
public string Value { get; set; }
}
}
Many thanks for spotting and fixing this! your a star

Probably simpler to replace the .FirstOrDefault(test) != null with .Any(test):
IEnumerable<Object1> myResults = myList.Where(m => m.theList.Any(o => o.Name == "Blah"));

I'm new to programming and is currently working on Windows Forms where i'm developing a basic Pong game. I'm trying to follow a video which shows how to make a simple Pong game but although it's easy to just copy the code being written i'm not really understanding what exactly is happening since it's not explained.
I'm particulary having trouble understanding the code blocks below.
This block of code is supposed to represent points being increased by one for player 1 i think:
if (ball.Location.Y < 0)
{
pl1Score++;
ball.Location = new Point(this.Width / 2, this.Height / 2);
}
but what does
if (ball.Location.Y < 0) mean? What does the if statement represent?
Aswell as:
if (ball.Location.X > player1.Location.X && ball.Location.X + ball.Width < player1.Location.X + player1.Width && ball.Location.Y + ball.Height > player1.Location.Y)
{
bvelY *= -1;
}
bvelY is a variable representing speed of the ball btw.
And another one is
if (ball.Location.Y > this.Height)
{
pl2Score++;
ball.Location = new Point(this.Width / 2, this.Height / 2);
}
That increases points for player 2 i think. But i'm not understanding the
if (ball.Location.Y > this.Height) statement
I haven't really found any tutorials or pages that explain these things, so that's why i'm asking here. Could someone give a good description of what these things mean? Would be appreciated.
Sorry if this may come off as a stupid question, i'm new here.

I think the code you are asking about is when the ball hits the edges of the area. Setting the speed *=-1 will bounce the ball when it hits the edge/wall in the other Y direction (if I understand your code correctly).

Are you referring to the
if (ball.Location.X > player1.Location.X && ball.Location.X + ball.Width < player1.Location.X + player1.Width && ball.Location.Y + ball.Height > player1.Location.Y)
{
bvelY *= -1;
}
block? What in the code determines that the ball hits the edges of the area and what do you mean by other Y direction?
And what about
if (ball.Location.Y < 0)
{
pl1Score++;
ball.Location = new Point(this.Width / 2, this.Height / 2);
}
It's my understanding that
pl1Score++; adds points to a player but what does
if (ball.Location.Y < 0) mean?

I'm assuming you know the Cartesian Coordinate system[^]. Every thing will be based on it.
if (ball.Location.Y < 0)
{
pl1Score++;
ball.Location = new Point(this.Width / 2, this.Height / 2);
}
In plain English this means; If the location of the ball is less than 0 then take the following actions. Update player ones score and give the ball a new location in the middle of the screen.
Assuming your paddles are at the top and bottom of the screen this means that player one just score a point against player two.
if (ball.Location.Y > this.Height)
{
pl2Score++;
ball.Location = new Point(this.Width / 2, this.Height / 2);
}
This means exactly the same except the ball has traveled off the screen at the bottom.
if ( ball.Location.X > player1.Location.X
&& ball.Location.X + ball.Width < player1.Location.X + player1.Width
&& ball.Location.Y + ball.Height > player1.Location.Y)
{
bvelY *= -1;
}
This one is very similar in that you are making sure that the location of the ball in both the X and Y coordinate has not hit the player one paddle.
So the ball X coordinate must be greater than the player one X coordinate
AND
the ball X coordinate plus the ball width is less than the player one X plus the player one width.
(in other words does the ball line up with the paddle in the X coordinate.
AND
the ball Y coordinate plus the ball height is greater than the player one Y coordinate.
That whole if statement tells you if the ball hit the paddle then change the direction of the ball. I know it says speed but sometimes speed and direction are equivalent.
Jack of all trades, master of none, though often times better than master of one.

Thank you for a very clear description of what the code blocks mean, it makes more sense to me now

What you'e seeing in some cases is what's called "defensive programming"; e.g.
One assumes that if Y == 0, the ball is at "ground level"; and if Y = Height of container, it is "on the ceiling".
However, with "floating point calculations" (or some "logic"), you may never reach zero or height exactly; so one plays it safe by coding "(equal or) greater / less than" versus an "exact" value that might be missed.
In this case, the code goes or projects going "past" some "stopping point".

I see, so assuming there's one player at the top of the screen and one at the bottom, this code block
if (ball.Location.Y < 0)
{
pl1Score++;
ball.Location = new Point(this.Width / 2, this.Height / 2);
}
means the player from the bottom gets a point if the player from the bottom misses to hit the ball? Sorry if i'm being stupid here, but i'm trying to make sense of it

The ball "hits the floor" (the "Y coordinate" is less than 0).
We can assume that someone other than "pl1Score" missed. ("Player 2" perhaps).
The ball restarts in the middle of the screen.
