What makes you say that the code doesn't invoke? What I am trying to understand is, are you expecting some result which is not happening?
A quick test would be putting a writeline to see what the passed in argument is coming as.

I think you are talking about "Size on disk", if its that then Size on disk is calculated by block size, each file saved in blocks. In NTFS, the block size is 4096 bytes( 4 KB ) that mean if your file size is 1 KB then it will take 4 KB, 3 KB will be padding to align the other data. So if you gonna need Size on disk then you can use
(long)Math.Ceiling((double)fileinfo.Length / 4096);
Note : it was about NTFS, dunno about FAT

That's pretty rubbish.
- Cluster size depends on formating options. The default cluster size depends on file system (NTFS, FAT[32], exFAT...) and on the size of the disk.
- Files can be compressed at cluster level which has huge impact.
- Files can be fragmented.
- Files can be on another drive (yes, symbolic links exist on NTFS)
- Sparse files (which by definition don't actually take on the disk their size initially)
- ...

Your form needs to be in a dll, then you can import it, and create instances of it.

Hi,
I have a form that has one combobox. I have already populated the combobox with data from a sql database by creating a method in the form_load.
How can I create a class file and then move my method to the class so that I can use that one method over multiple forms? It basically comes down to refactoring but I am having difficulty understanding the properties I need to do this...
My current method looks like this
private void PopulatePhysicalSuburbs()
{
DataSet dsPhysicalSuburbs = new DataSet();
dsPhysicalSuburbs.Merge(proxyGetData.GetSuburbs());
cbPhysicalSuburb.DataSource = dsPhysicalSuburbs.Tables["Suburb"];
cbPhysicalSuburb.DisplayMember = "Suburb";
cbPhysicalSuburb.ValueMember = "Id";
}
Illegal Operation

Well, this is redundant, it looks to me like you've done all you can.
Illegal Operation wrote: DataSet dsPhysicalSuburbs = new DataSet();
dsPhysicalSuburbs.Merge(proxyGetData.GetSuburbs());
Is dumb. You create, then throw away a dataset.
DataSet dsPhysicalSuburbs = proxyGetData.GetSuburbs();
Then the rest, is stuff that needs to happen in the class that has the combobox. Your next level of abstraction is to create a control that knows to load it's own data source, and reuse that

Do you know of any good articles about creating a custom control like that?

hi everyone,
using System;
using System.Collections.Generic;
using System.Text;
using System.IO;
using System.Collections;
namespace arraylist
{
public struct ParameterValues
{
public ArrayList al;
};
public class Program
{
public static ArrayList alMix = new
ArrayList();
public static ParameterValues pValue = new
ParameterValues();
public static void Main(string[] args)
{
pValue.al = new ArrayList();
pValue.al.Add(5);
pValue.al.Add("vgbd");
pValue.al.Add('d');
alMix.Add(pValue.al);
alMix.Add(pValue.al);
//Now i want to ACCESS the elements of alMix array list
Console.ReadKey();
}
}
}
in the above program i have created an array list inside the structure and populated it.
The contents gets saved as,
pValue.al[0] = 5
pValue.al[1] = "vgbd"
pValue.al[2] = 'd'
Then i copied those values in another array list alMix where it is getting stored as.
alMix[0][0] = 5
alMix[0][1] = "vgbd"
alMix[0][2] = 'd'
alMix[1][0] = 5
alMix[1][1] = "vgbd"
alMix[1][2] = 'd'
Now since the alMix arraylist is 2D, i'm unable to access it. Please help in accessing the elements of the alMix array list which is 2-dimensional.?
thanx in advance.

A) No one uses Arraylists any more.
B) Try alMix[0].al[0]
C) Try ((Arraylist) alMix[0]).[0]
|
|
|
|
|
List cannot be 2D, Array can
ArrayList[] ai = new ArrayList[2];
ai[0] = new ArrayList();
ai[1] = new ArrayList();
or
ArrayList ai = new ArrayList();
ArrayList childai = new ArrayList();
childai.Add("MyName");
ai.Add(childai);
string name = ((ArrayList)ai[0])[0].ToString();

Hi to all!
I'm using a PPP to connect two Gsm Devices through serial port. When i receive data from remote device, some characters are randomly appearing. I've been reading some documentation about those XonXoff characters, but i don't know how to deal with them. There's any way of avoiding those characters or to make my program correctly interpret them?
Best regards.

Hi,
Serial communication needs a way to prevent more data coming in than can be handled, the solution is called "handshaking" which basically is the receiver asking the transmitter to stop/resume sending. In Windows handshaking is handled by the driver, the application is not involved apart from selecting it.
when using "software handshaking" you set SerialPort.Handshake to Handshake.XonXoff and the serial driver will process the ASCII characters Xon and Xoff in a special way: it will send Xoff to indicate it can not accept any more data (buffer almost full), and Xon for the opposite.
The advantage is you don't need two extra lines to do "hardware handshaking".
There is one important limitation: you are not allowed to send data that contains Xon and Xoff characters;
if these occur they will be interpreted by the driver at the receiving side (probably interfering with the handshake), and they will not reach the application, so they are lost.
BTW: the normal values for Xon and Xoff are CTRL/Q and CTRL/S; the Windows driver allows you to select different characters for these, AFAIK the SerialPort class does not.
