DevExpress.XtraGrid.Views.Grid.GridView MyGridView = new DevExpress.XtraGrid.Views.Grid.GridView();
You have created a new empty grid in this function, so none of the cells will contain any data.

Dear Mr.Richard MacCutchan,
Thansk for your instruction
I want to get cell value on some grid via only one function
so the input parameter of this functon is a grid. How to get cell value on the grid(input parameter)?
Help me please

Just like it is ok
public void ShowValueOnGrid(DevExpress.XtraGrid.GridControl grd)
{
String sValue="";
int m=0;
for (m = 0; m <= ((gridview)grd).RowCount; m++)
{
sValue = ((gridview)grd).GetRowCellValue(m,“InvoiceNO").toString());
MessageBox.Show(sValue);
}
}

Check the documentation for the method(s) to access individual cells.

I understand how to create animation like pacman, but to move the pacman, I can only think of using location.
Problem is, how could I know there is obstacle or not?

Ultimately, the object will have a coordinate. This could be used to perform a rudimentary collision detection. The process could be as simple as this:
public class BaseGameObject
{
public int X { get; set; }
public int Y { get; set; }
}
public class GameObjects : BaseGameObject
{
public List<BaseGameObject> GameObjects { get; set; }
public BaseGameObject HitTest(int x, int y)
{
foreach (BaseGameObject gameObject in GameObjects)
{
if (gameObject.X == x && gameObject.Y == y)
{
return gameObject;
}
}
return null;
}
}

Thank you very much for the help.
I will try to understand it as I never use get set or that kind of class.

What you are looking for, as the above poster pointed out, is Collision Detection, you should be able to find plenty of sources on it, I will list a few:
Collision Detection[^] on wikipedia (theory)
Testing for Collisions[^] on MSDN, this is for (the now unsupported) XNA Framework
Pacman in C# (map & collision detection)[^] A question here in CodeProject
C# Game Programming for Teens[^] In this book you will follow the chapters to make a 2D Dungeon Crawler. Chapter 4 deals with collision detection
EDIT:
If you are using sprites (which I guess is the case) you have to check if the object's rectangle intersects with any other object's rectangle, take into account that the rectangle also counts the transparent pixels of your sprite. You could do your own way of checking for an intersection between two rectangles, but you can use the IntersectsWith[^] method.
If your object is non-player controlled, it most likely has a velocity, so you can predict the collision by calculating the coordinates for the next iteration and checking for intersections with those coordinates.
Example:
Player controlled object:
public class PlayerObject
{
public Point Location {get; set;}
public Size ObjectSize (get; set;}
public Rectangle Bounds {get; set;}
public PlayerObject(Point loc, Size objSize)
{
Location = loc;
ObjectSize = objSize;
Bounds = new Rectangle(Location.X, Location.Y, Location.X + Size.Width, Location.Y + Size.Height);
}
public bool IsColliding(ref GameObject obj)
{
bool collides = Bounds.IntersectsWith(obj.Bounds);
return collides;
}
}
If you think you can do a thing or think you can't do a thing, you're right - Henry Ford

Hi all,
please excuse that I like to get your attention to my post in the "Regular Expressions" section  . Unfortunately, the forum there seems to be fairly unattended... to avoid crossposting (to the sensible extent), I put my question there, hoping someone of you helps me out of some more sophisticated (I guess) regex stuff.
Thank you very much,
Mick

Avoiding it? I also came across the same question in the VB.NET forum.

Ah, so it's allowed because it's urgentz?
Sorry, I'm gonna skip this one.

SORRY, I meant that I'd deleted this post as well as the original question in the "Regular Expressions" forum, which I saw didn't have any questions or answers since february... BTW deleting both of them was my only idea after I saw how someone anonymously downvoted my question in the C# forum - why it didn't work here I can't tell, deletion of the original obviously worked (broken link).
But instead of ranting, you might at least give your advice on how you would stay with the forum structure and still reach someone of the community who might even be in a better mood and willing to help.
It seems that this post isn't deletable anymore now (maybe because of your helpful answers). But it's been downvoted anyway... So thanks for your time - and have a better weekend.![Rose | [Rose]](https://www.codeproject.com/script/Forums/Images/rose.gif)

Most readers will check multiple forums here; it's annoying to come across the same question over and over. The board also highlights the places with "new" messages, so it kinda feels impatient.

Yes, could have been friendlier. Make that "should have been".

This post serves no purpose, and your link appears to be broken. Please follow the rules and post in one place only.

SORRY, Richard,

Maybe you can recognize my attempt to follow the rules.
I'd posted the original question in the VB forum, as I said meaning to have the other ones deleted. Now it seems that this post isn't deletable anymore now (maybe because of being answered now). I will if you can tell me how to do it.
Thank you still [Rose]

I've tried my best first, by putting the question into a completely unattended forum and linking to it. What would you suggest to do in such a case? Wait another four months? I wonder why unattended forums aren't closed down...
And: Can a place which is visited be a wrong place, anyway? My posting there resulted in a good, simple and working solution of the problem some minutes ago, from someone who looked at the question itself instead of judging helpless attempts to follow the rules for the remaining rulebreaking. I guess that's what a forum needs and what other searchers want to read even after years, right?
I'm German and know a lot about useless formalities - this seems like one of them. All I did was what you yourself write in your signature:Richard MacCutchan wrote: Use the best guess

There is no such thing. Each forum is dedicated to a different subject and peple who are interested in that subject will visit those forums in their own time. The site makes no guarantees about responses or their validity.

There is insufficient memory. Save the document now. (C:\...\ACL-PhillipSholar_1482.doc)

Is it a 64 bit server? It may be an issue with that.

hi
i have a question about help file button and f1 keydown property in c#.
can we have in a form help button and keydown property about help(with press F1 key) ?
i use the following commands for the key :
-------------------------------------------
if (e.KeyCode == Keys.F1)
{
Help.ShowHelp(this, "Help.chm");
}
and for the help button:
-----------------------------
Help.ShowHelp(this, "Help.chm");
But only one of the two methods are working the other one activated when start other one method.
for example if when i press F1 key is activated the help file then if i press the help button will work too but if i close the running program and i will start again and press help button without press f1 key before then the button does not working.

I am writing a new C# 2010 desktop application. This application will allow users to select a file from a specific directory location. I am wondering is there anything in a windows application called 'type ahead' feature? Basically
the user will stat typing a few letters and all the files in a selected directory path will appear. (I am asking this question since this feature is available in web applications.)
If there is this type of a feature, can you tell me what this feature is? In addition can you tell me and/or point me to a reference that will tell me how use the 'type ahead' feature?

public void Foo(Bar bar)
{
if (bar== null)
{
bar = new Bar();
}
}
--- or ---
public void Foo(Bar bar)
{
bar = bar ? new Bar();
}
Which do you think is better?
[Edit]
Thanks all for your help. I opted for 1 (it was the original code so I know it'll make it through the code review) and easier for newer devs to understand. I might drop the {}.

I prefer the first one. I only use ? or ?? in places where an if isn't allowed.
But I'd probably throw an Exception in the case you show.
