C# Adding to An ArrayList - C# Discussion Boards

well thanks,
but thats the way emails are already generated, with multiple To,CC addresses..

Its not the fall that kills you; it's the
sudden stop at the end.

You can also eliminate the round trip throught the server:

SmtpMail.SmtpServer = "localhost";
eMail.Fields["http://schemas.microsoft.com/cdo/configuration/sendusing"]=1;
eMail.Fields["http://schemas.microsoft.com/cdo/configuration/smtpserverpickupdirectory"] = "C:\\Inetpub\\mailroot\\Pickup";
SmtpMail.Send(eMail);

its from System.Web.Mail which has been depricated now.

Hi,
There is a SendAsync method, which is of your use, i think.

thanks,
internally it will spawn a thread to do my work,
this will definately fasten up things,
but if i can get that single connection for sending mails it will be great

SmtpConnection class is there but its not exposed otherwise i could have achived behaviour seamlessly.

hello programmers!
im creating an application to hold my dvd collection (lame, but i have to start somewhere!)
and im having problems adding a DVD object to an ArrayList.

basically...i have a "DVD" object which is coded as follows:-

using System;
using System.Collections;
using System.Text;
using System.IO;
using System.Runtime.Serialization.Formatters.Soap;
using System.Windows.Forms;

namespace DVDDatabase
{
[Serializable]
public class DVD
{
//DVD Properties
public string strTitle;
public int intBoxLocation;
public int intBoxNumber;
public DateTime dtDateAdded;
public int intYear;
public string strGenre;
public string strDirector;
public bool boolWatched;
}

[Serializable]
public class Collection
{
public ArrayList arrDVDCollection;
}
}

(note this is in a seperate .cs file)
so, what i want to do is create an instance of "Collection" at run time right? so, my main method is as follows...

static void Main()
{

//Starts The Application
//Load Preliminary Objects
Collection DVDCollection = new Collection(); <<--HERE IT IS!

//Load GUI
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
Application.Run(new MainMenu());
}

ok, so now, on an "Add DVD" button that i have on a SEPERATE form (called AddDVD.cs) i need a command to add the current DVD object to the array list...here we go again!

private void btnAddDVD_Click(object sender, EventArgs e)
{
//create new instance of dvd object
DVD newDVD = new DVD();
//set properties
//set Title
newDVD.strTitle = txtTitle.Text;
//add Dateadded code here
//Set Year
try
{
newDVD.intYear = int.Parse(numYear.Text);
}
catch (Exception)
{
MessageBox.Show("Please Input A Number For Year");
}
//set Director
newDVD.strDirector = txtDirector.Text;
//add Gennre Code Here
//set BoxNo
try
{
newDVD.intBoxNumber = int.Parse(txtBoxNo.Text);
}
catch (Exception)
{
MessageBox.Show("Please Input A Number For Box Number");
}
//set BoxLocation
try
{
newDVD.intBoxLocation = int.Parse(txtBoxLocation.Text);
}
catch (Exception)
{
MessageBox.Show("Please Input A Number For Box Location");
}
//Set Watched Bool
newDVD.boolWatched = chkWatched.Checked;

//add to array list
DVDCollection.arrDVDCollection.Add(newDVD); <<-HERE IT IS!
//Clear form
}

yeah i know i havent coded everything, but im getting there!

anyway, when i compile i get the following email message:-

"the name DVD Collection does not exist within the current context"

i think this is because the original ArrayList definition is not being referenced on the above form (or something like that) but i am unsure how to go about doing that.

if somebody can understand any of that mess i have just written out and offer some help, i would be very thankful

At first glance, you need to initialize the instance of arrDVDCollection in the Collection constructor.

Yep, I couldn't find any code that does instanciate the arraylist object.

Change
[Serializable]
public class Collection
{
public ArrayList arrDVDCollection;
}
}

to
[Serializable]
public class Collection
{
public ArrayList arrDVDCollection = new ArrayList();
}
}

You're done Wink | ;-)

Actually, part from the other answers, DVDCollection is created as a variable in the Main() method so it isn't declared in your btnAddDVD_Click method, so just make it a field of AddDVD class.

Offtopic: I would suggest reading some books about object oriented programming, declaring all your fields as public isn't the way you should be programming Smile | :)

Hi Friends,
I want know to create shared assembly, i know how to create strong name but i will not able to invoke shared assembly. Any one helps me to come out this suitation.
Smile | :)

Have you added the assembly to the GAC (Global Assembly Cache) ??

- - - --[ i love it when a plan comes together ]-- - - -

I have added assembly to GAC but i am not able to invoke that assembly in application Smile | :)

And you DO have a reference to the assembly??

- - - --[ i love it when a plan comes together ]-- - - -

when i am not able to add a reference is it any other to invoke shared assembly.

Here is a turn up from my google[^] search.

Hi,

i am creating a form to display the actions done to file in a directory.
For the add, delete and rename actions a write line in a textbox.

The directory is accessible through a windows share (on my local machine) and now i am trying to get the username of some external user who is also modifying files on my shared directory.

How can this be done? i now only get the username of the logged in user (being myself ...)

Open the file and read the contains of the file to a string.
Then use, for example:
string myText = myText.Replace("apple", "mango");

But i have to save the contents to the file also.........
how do i save them into the file?

Sankalp Verma

Use StreamWriter. Read MSDN.

Hi there,

I have the following problem:
I want to add a variable 'myServerInfo' to an arraylist.
This variable is of the datatyp 'ServerInfo' (public class).
I can add this variable without any problems to the arraylist with
the command:

<br />
myServerArrayList.Add(myServerInfo);<br />

But how can I have access to this through the arraylist?
If I type in the following commandline, Intellisense will not
provide me the necessary information:

<br />
Console.WriteLine(myServerArrayList[0].???<br />

I thought I can type in:

<br />
Console.WriteLine(myServerArrayList[0].strServerName);<br />
Console.WriteLine(myServerArrayList[0].strServerIP);<br />
Console.WriteLine(myServerArrayList[0].strServerNetMask);<br />

My complete code for this example is like:

<br />
using System;<br />
using System.Collections.Generic;<br />
using System.Text;<br />
using System.Collections;<br />
<br />
namespace ConsoleApplication1<br />
{<br />
    public class ServerInfo<br />
    {<br />
        public string strServerName;<br />
        public string strServerIP;<br />
        public string strServerNetMask;<br />
    }<br />
<br />
    class Program<br />
    {<br />
        static void Main(string[] args)<br />
        {<br />
            ArrayList myServerArrayList = new ArrayList();<br />
            ServerInfo myServerInfo = new ServerInfo();<br />
            myServerInfo.strServerName = "Server 1";<br />
            myServerInfo.strServerIP = "192.168.0.1";<br />
            myServerInfo.strServerNetMask = "255.255.255.0";<br />
            // Add to ArrayList<br />
            myServerArrayList.Add(myServerInfo);<br />
            Console.WriteLine(myServerArrayList[0].???<br />
        }<br />
    }<br />
}

If anybody gives me a hint,
I can go on with my project. Smile | :)

Thanks in advance

Erik
