Or simply:

using System;
using System.IO;
using System.Collections.Generic;
using System.Linq;

class MainClass {
   public static void Main() {
      Console.WriteLine("Input file name to open!");
      Console.WriteLine("Sample: d:\\filename.txt");
      File.ReadAllLines(Console.ReadLine()).ToList().ForEach(Console.WriteLine);
   }
}

Despite everything, the person most likely to be fooling you next is yourself.

Hi
I am using the Zedgraph addin to plot some curves. I would like to add labels to each curve individually instead of having a legend on the right-hand side. Can anyone shed some light on this?

Thanks,
Alex

have you consulted Zedgraph genie, I mean, Wikki[^], how about this[^]

Yusuf

Oh didn't you notice, analogous to square roots, they recently introduced rectangular, circular, and diamond roots to determine the size of the corresponding shapes when given the area. Luc Pattyn[^]

Hi Yusuf,

Thanks for the tip, I have looked there and there is someone else with the same problem but I don't see a solution. There seems to be a function with pie charts but still no idea for line graphs?

UAC and iterating files (manifest)

Hi
I have written a small program to search my computer for certain files. However, I use Vista which has UAC. Unfortunately there are plenty of places where the application can't reach because of permissions. So I decided to search around how to get past the permission problem. I found the following guide:

http://blogs.msdn.com/shawnfa/archive/2006/04/06/568563.aspx

As expected my app now asks when launched to get highest possible permissions when running. Unfortunately, this still prevents me from accessing the same folders. Any suggestions why that is? Have I lost control of my own system or something since it can't even access my own home directory?

There are folders on the disk that you cannot get to, no matter what accoutn you use. Your code is just going to have to deal with this eventuality.

If you've already made a manfiest file for your app, requesting admin priv's, then that's about the limit of what you can do.

I can't think of a definitive list, but the first that springs to mind is System Volume Information. However, it would be fairly simple to get a list yourself. Just recurse, but print the directory name to the console if you catch an UnauthorisedAccessException. Leave it for a few minutes/hours and you have a list

Hi Dan,

I don't know them all, I trust C:\System Volume Information and C:\C:\Users\All Users\Start Menu are two of them.

"System Volume Information" for one. I seem to remember there was another folder, but I can't remember the name right now.

Global Event Handler?

musefan9-Mar-09 7:49

Hi all,

Im not quite sure what i want to use for my problem so i thought maybe somebody out there has a good solution.

My situation is that i have a user control that, for example, displays a list of database entries such as messages. This control can be present in multiple forms that esentially need to be syncrhonised. For example, if an entry is added, edited or deleted in one control, all other controls need to be notified of this and know to look for updates.

As my subject may suggest I have thought of a global event that all instances can listen for, but have not tried yet as i dont know if this is a good option.

Does anybody know of any 'best practice' solutions for this situation?

I usually find my answers with google, but in this instance im not even sure what im searching for.

Thanks

If all the events have a similar signature, Delegate.CreateDelegate (starting with .Net v2.0, it supports covariance) and EventInfo.AddEventHandler should help.
However, if you absolutely must use methods with completely different method signatures, then try this approach

You don't make this a "global" event. This would probably be an event exposed by a singleton data store you create. An event can have multiple subscribers, but since you're sharing data acrossed multiple instances of your control, it would suggest using a central data store to back all instances of the control.

Agree with Dave. In your case, no need to create a "complex" global event manager. Just update the UI when you modify the data. Simplicity is always good. Big Grin | :-D

Change property´s value description

Hi everybody,

I want to show a property´s value description other than the original in the PropertyGrid control. For example:
I inherited from TextBox control and I want the Visible property´s value description be "Verdadeiro/Falso" instead of "True/False".

Verdadeiro means True in portuguese, and Falso means False.

Anyone know how can I do that?

Thanks. Smile | :)

musefan9-Mar-09 7:53

well you can use xml tags to write descriptions. If you have VisualStudio or something similar, try writting '///' before the Visible funstion (which i think you will have to override) and it should give you a template. Or Look Here[^]

I think that answers your question, right?

No, it doesn´t answer.

But is not your fault, I forgot to mention that the value description is to appear in the PropertyGrid control.

DataGridViewComboBoxCell closes immediately [modified]

Hi Guys,

I'm experiencing the following problem with DataGridViewComboBoxCell:
When clicking the arrow that opens the combo box for the first time, everything is fine. However, when clicking it again (as long as the cell is still in focus) the list drops (opens) and closes immediately. The only way to change its value is to select another component so it loses focus, and then click it once again.

Does anyone has an idea how to solve it?

Thanks,

Eyal.
