i have a question

using C# VS2010,

validate a textbox against IP AddresS(E.G local computer IP Address) on click event
input it into a textblock/label?

Yes.

What is your question?
What part of this is giving you a problem?

Use the TextBox.Text property.

string s = myTextBox.Text;

Rei ho wrote:
IP AddresS

Use the IPAddress class: MSDN[^]

Rei ho wrote:

Use TextBox.Text property the other way:

myTextBox.Text = "It matches!";

I repeat: which part of this are you having difficulty with?

Quite likely; but I will give the OP the benefit of the doubt and assume that it's a language problem, given his name and location. If he still doesn't understand I will suggest the Chinese forum and see if that helps him / her. Laugh | :laugh:

Highlighting the text in random parts isn't enough. You need to let us know how far you've got with the code, what exceptions or problems you are having in it. We won't write the whole thing for you - we don't need to pass your class; you do.

I'm not a stalker, I just know things. Oh by the way, you're out of milk.

Re: Textbox Validation against IP [SOLVED]

private void okBtn_Click(object sender, RoutedEventArgs e)
{

string ipbox = IPBOX.ToString();
string ipAddress;
ipAddress = Dns.GetHostEntry(Dns.GetHostName()).AddressList[0].ToString();

if (string.Equals(ipbox,ipAddress))
{
ipAdd.Content = ipAddress;
}

else
{

Validates.Text ="Test";

}

}

Sorry, i really suck at programming,
i am using the coding that i typed above
But it keeps going to

Validates.Text="test" even when i type the correct String

I have a DataGrid created in XAML like this:

<DataGrid Name="gridPersons" Margin="0,0,0,0" HorizontalAlignment="Left" VerticalAlignment="Top" Width="390" Height="440" IsReadOnly="True">
    <DataGrid.Columns>
        <DataGridTextColumn Header="Name" Width="180"></DataGridTextColumn>
        <DataGridTextColumn Header="Age" Width="180"></DataGridTextColumn>
    </DataGrid.Columns> 
</DataGrid>

I also have a class to store data in:

class Person
{
    public string name;
    public int age;
    public string phoneNumber;

    public Person(string name, int age, string phoneNumber)
    {
        this.name = name;
        this.age = age;
        this.phoneNumber = phoneNumber;
    }
}

As well as populated a list to keep some data in:

static void Main(string[] args)
{
    List<Person> persons = new List<Person>();
    persons.Add(new Person("John", 25, "123456789");
    persons.Add(new Person("Tim", 20, "987654321");
}

Now I would like to foreach loop through the List<Person> into the DataGrid.
Each instance is a row in the grid and each row contains of only name and age property.

This was very easy in Windows Form Application, but in WPF I found this difficult Confused | :confused:

Any help?

Loading a video from a web server and displaying it on my application

Rei ho24-Jan-11 20:30

Re: Loading a video from a web server and displaying it on my application

24-Jan-11 20:30

Hello,

I am currently having a problem loading a video from a web server and then making it display on my expression blend 4 WPF C# application

Currently, the video is loaded out from within the application folders

Video.Source = new Uri(@".\Videos\Network\network_(a).wmv", UriKind.Relative);
Video.Play();

however i want to load it from a webserver and displaying it on my application

instead of @".\Videos\Network\network_(a).wmv"
what code should i use to change it

@"192.x.x.x\network_(a).wmv"

or perhaps using C# code to download from the web source and then display?

sorry, as i am relatively new in this field

For a start you will need to include the HTTP or FTP protocol you are using

"http://192.x.x.x\network_(a).wmv"

That will definitely help get closer to resolving the issue

Architecture is extensible, code is minimal.

I tried doing "http://192.x.x.x\network_(a).wmv"
However it doesn't load and plays the video

Again , the coding on my C# event handler is currently

Video.Source = new Uri(@".\Videos\Network\network_(a).wmv", UriKind.Relative);
Video.Play();
which loads the video from my video folder

Ok, did you change the UriKind to Absolute?

What is the Video object. Can you tell us the name of the video class and it's full namespace?

Extracting numeric from string

I want to extract numbers from a string [Shipment ID]
"string sentence = "Shipment ID: 212857,1212,Invoice No: 1202127, 25-JAN-10 (PDF) "

so the extracted numbers will be 212857 and 1212

I have tried with Regex but not getting the desired result.
Can anyone help

String data = Regex.Match(sentence , @"ID:\d{10}", RegexOptions.IgnoreCase).Value;
string[] digits = Regex.Split(sentence, @"\D+");

string pattern = @"\b[0-9]+\b";
            string input = "Shipment ID: 212857,1212,Invoice No: 1202127, 25-JAN-10 (PDF)";

            foreach (Match item in Regex.Matches(input, pattern))
                Console.WriteLine(item);

            Console.ReadKey();

Try this...

You should have posted this to the Regular Expressions forum[^], but try using named groups and processing the line more carefully:

string s = "Shipment ID: 212857,1212,Invoice No: 1202127, 25-JAN-10 (PDF)";
Match m = Regex.Match(s, @"ID:\s(?<SID>\d+),(?<SID2>\d+)");
Console.WriteLine(m.Groups["SID"].Value + "," + m.Groups["SID2"].Value);

But this will hard code the "ID" string.

Precisely. It targets the information the OP requested, rather than returning spurious information that then needs further processing to remove or ignore.
