The code you have given us looks ok - so it's time to look at your data.
What does the row giving the problem look like?

I think it's not the data, but the columns name; as soon as it gets mapped, it'll recognize the illegal name. It'll be valid in Excel, but not in a real database.
Simple solution; rename the column, remove the dot.

Could be - but I'd expect OleDb to cope better than that.
Be good to see the actual data so we can duplicate the fault.

I have a winform and a picturebox.
In the picturebox I´m running a XNA-game.
In the winform I have:
Game1 game = new Game1();
public Game1 Game
{
get
{
return game;
}
set
{
game = value;
}
}
In the XNA-form I try
public Form1 form = new Form1();
public Form1 Form
{
get
{
return form;
}
set
{
form = value;
}
}
I can via methods send info to the game using:
game.StartBoat();
where StartBoat is a method in my XNA-game.
I would like to send info to the winform also.
But I get a stackoverflow exception indicating an infinite loop. How should I do it if possible?

That code does not make much sense, in both cases the get and set would seem redundant.

Well, I´m not a superexpert in C# and certainly not XNA so I have got a lot of help via forums.

If one of those is responsible for creating the other, don't new up the original one in the new one. So, if Form1 creates Game1, don't do new Form1() in Game1. That will clear your stack overflow.
Now, as to the second part of your problem. There are a few things you could do to get around this. The first method is to pass a reference to Form1 into the1 Game constructor (or explicitly set it at some point before you try to use Game).
public class Game1 : Game
{
private Form1 form;
public Game1(Form1 form)
{
this.form = form;
}
}
public class Form1 : Form
{
private Game1 game;
public Form1()
{
game = new Game1(this);
}
}The other way to do this, and the way I tend to prefer, is to use events in Game1 to signal that Form1 should do something. By using events, you decouple Game1 from having to know anything at all about Form1 - which means you could swap it into other projects far easier. Basically, after you instantiate Game1 in Form1, you can subscribe to the events that you're interested in and use those as appropriate.

You need to create a Server/Client system that will allow multiple terminals to connect. Google for "C# sockets" and you will find lots of information.

I decline to answer, purely because you SHOUTED at us.
Using all uppercase on the internet is counted as shouting, and rude - and you probably shouldn't start off by being rude to people when you want their help...

THIS DOESN'T REALLY LOOK LIKE A C# QUESTION
|
|
|
|
|
Hi,
What knowledges are required before learning c#..like JQuery, Ajax,etc...?
|
|
|
|
|
The ability to use and administrate Windows. That's about it.
|
|
|
|
|
As long as you can think logically, like to solve problem using computer, be it C# or other programming languages, go ahead and just do it. Along the way, you may find yourself needing a database or web site or some other technologies, then you can start to learn these stuffs when such needs arise. Read this: Start-Learning-Computer-Programming[^]
|
|
|
|
|
No knowledge is required; all of us, at some point, started from a beginning. Of course, however, any other programming languages you have learned may contribute to the speed, and ease, with which you are able to learn another language (or, they may not, if you have never understood the general principles involved in the structure of any programming language).
I'd recommend getting a good basic book on C#, and getting busy. There's a good on-line book, and source-code for the examples in the book, from Charles Petzold available for download here: [^].
Why not start right now ?
