Re: Array.getLength() vs Array.getUpperBound()

getLength returns the total number of elements and getUpperBound returns the highest index number (getLength - 1) in most cases. getUpperBound can also be used on arrays of 2 or more dimensions to get the upper index of a dimension.

Is there a difference between the two?

Yes.

GetLength returns the number of items in the specified dimension.

GetUpperBound returns the index of the last item in the specified dimension.

For a one dimensional zero based array (which is the usual) that holds 10 items, GetLength(0) returns 10, while GetUpperBound(0) returns 9.

Yes, GetUpperBound is used to get the boundaries of different dimensions of an array. Call GetUpperBound(0) to get the upper bound of the first dimension, GetUpperBound(1) for the second dimension and so on. It's in case you're using a 2-dimensional (or higher) array. Also, GetUpperBound returns the highest index of that array instead of the number of values in that array. So, whereas you would do for (int i = 0; i < arr.Length; i++) for length, you would do this for the upper bound: for (int i = 0; i <= arr.GetUpperBound(0); i++)

Serializing in RESX file?

Hey all,

I'm trying to create a working TypeConverter for a custom class, but it's causing me no end of problems. At the moment, everything seems to be working except for the code generation. Rather than initialising the objects in InitializeComponent, the designer is trying to do so via the Form's RESX file.

The relevant line in the InitializeComponent function looks like this;

this.graph1.Point = ((Root.Graph.GraphPoint)(resources.GetObject("graph1.Point")));

And in the RESX file, I have this;

<assembly alias="Graph" name="Graph, Version=1.0.0.39852, Culture=neutral, PublicKeyToken=null" />
<data name="graph1.Point" type="Root.Graph.GraphPoint, Graph">
<value>5, 3, 2, 1</value>
</data>

It doesn't actually compile by the way - it seems to break the RESX file. But that's not the issue. Does anyone have a clue as to why it might be serializing my object in the RESX file, and not just initializing it as normal in InitializeComponent?

Thanks.

I wrote this class:

<br />
  public class Send_Mail<br />
    {<br />
    <br />
        public void send()<br />
        {<br />
            string to = "snaidis@gmail.com";<br />
            string from = "semionn.89@mail.ru";<br />
            MailMessage message = new MailMessage(from,to);<br />
            message.Subject = "Using the new SMTP client.";<br />
            message.Body = @"Using this new feature, you can send an e-mail message from an application very easily.";<br />
            SmtpPermission permission = new SmtpPermission(true);<br />
            SmtpClient client = new SmtpClient("smtp.mail.ru");<br />
            //client.UseDefaultCredentials = true;<br />
            client.Send(message);<br />
<br />
        }<br />
    }<br />

When I run it I have the following problem:

<br />
An unhandled exception of type 'System.Net.Mail.SmtpException' occurred in System.dll<br />

The following worked for my ISP. mail.bellsouth.net and 25 are the SMTP server name and outgoing port number respectively.

private void btnTestEmail_Click(object sender, EventArgs e)
{

try
{
using (MailMessage message = new MailMessage(myEmail, myEmail, "subject1", "body1"))
{

SmtpClient mailClient = new SmtpClient("mail.bellsouth.net");

mailClient.UseDefaultCredentials = false;
CredentialCache myCache = new CredentialCache();

myCache.Add("mail.bellsouth.net", 25, "Basic", new NetworkCredential(myUserName, myPassword));

mailClient.Credentials = myCache;

mailClient.Send(message);
}
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
}

Good Luck.

They've been all but gone from the net for years spammers would find and abuse them and the owner would have to implement authorization to get off blacklists.

Since UseDefaultCredentials defaults to true, perhaps you just need to explicitly set if false.

Have you replaced "MyAcc" "MyPass" with the user name and password for your account on the email server? Your user name is probably "semionn.89", I can't tell you what your password is. Big Grin | :-D

OK on simple example, I know how to do it with one object

say something like this is done:<br />
XmlSerializer ser = new XmlSerializer(typeof(ArrayList), new Type[] { typeof(SomeClass) });<br />
XmlTextWriter writ = new XmlTextWriter("List.xml", System.Text.Encoding.UTF8);<br />
ser.Serialize(writ, SomeList);<br />
writ.Close();

Can you show me example, loading for example two ArrayLists each hold diferent type of data...

Well, if the definition is in a different source file, Ctrl+Tab will take you back. If it's in the same source file, set a bookmark first. There might be a keystroke to return you to your previous location, but I'm not aware of one.

CTRL/- goes to previous location ("navigate backward")
and CTRL/SHIFT/- is "navigate forward"

There are buttons for them on the "View" toolbar

Such buttons can show tooltip including shortcut
(enable thru Tools/Customize/Toolbars/Show ScreenTips on toolbars)
