I have this class,

path = label;
}
catch(Exception e)
{
MessageBox.Show(e.ToString());
}
Grid.SetColumn(imgclose, 0); Grid.SetRow(imgclose, 1);
this.Children.Add(imgclose);

}

{

}
void conitem2_Click(object sender, EventArgs e)

}

{
if (System.Windows.MessageBox.Show("Are you sure?", "Confirm", System.Windows.MessageBoxButton.OKCancel, System.Windows.MessageBoxImage.Question) == System.Windows.MessageBoxResult.OK)
{
ImageBoxes.Remove(this);
(this.Parent as System.Windows.Controls.Canvas).Children.Remove(this);
}
else
{
}
}
}
This class displays an image (chosen from a dialog box).
How can I modify it to make it play a video file ?
More precisely,
How should I modify the line
this.Background = new System.Windows.Media.ImageBrush(new System.Windows.Media.Imaging.BitmapImage(new Uri(label)));
path = label;
so that it plays a video file.
The Background property has to have some sort of Brush in it. A quick Google search came up with this: VideoBrush. I hope this is what you were looking for.

Сannot update form butReset_Click does not work RestoreLayoutFromRegistry from another form. How to do it right? I created one form from another and it is necessary to reset the pivotGridControl settings from 2 forms. I can't reset the settings.
namespace WindowsFormsApp4
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
butReset.Click += new System.EventHandler(butReset_Click);
pivotGridControl1.SaveLayoutToRegistry(regKey);
}
string regKey = "DevExpress\\XtraPivotGrid\\Layouts\\PivotGridLayout";
public Button butLoad = new Button();
public Button butReset = new Button();
public void LoadBtn_Click(object sender, EventArgs e)
{
Form1 fr = new Form1();
Form form = new Form();
form.Show();
ListBox listBox1 = new ListBox();
listBox1.Size = new System.Drawing.Size(200, 100);
listBox1.Location = new System.Drawing.Point(10, 10);
form.Controls.Add(listBox1);
listBox1.MultiColumn = true;
listBox1.SelectionMode = SelectionMode.MultiExtended;
DirectoryInfo dir = new DirectoryInfo(#"E:\");
FileInfo[] files = dir.GetFiles("*.txt");
butReset.Text = "Сбросить настройки";
butReset.Location = new Point(140, 160);
form.Controls.Add(butReset);
butLoad.Text = "Принять";
butLoad.Location = new Point(30, 160);
form.Controls.Add(butLoad);
var fileNamesWithoutExtension = files
.Select(fi => Path.GetFileNameWithoutExtension(fi.Name));
foreach (string fn in fileNamesWithoutExtension)
{
listBox1.Items.Add(fn.ToString());
}
}
private void SaveBtn_Click(object sender, EventArgs e)
{
pivotGridControl1.RestoreLayoutFromRegistry(regKey);
}
static public void butReset_Click(object sender, EventArgs e)
{
Form1 er = new Form1();
er.pivotGridControl1.RestoreLayoutFromRegistry(er.regKey);
//MessageBox.Show("dsdsdfsdf");
}
}
}
Use PivotGridOptionsDataField.Reset() method to Resets all options to their default values. In your case
static public void butReset_Click(object sender, EventArgs e)
{
pivotGridControl1.Reset();
}

I have a program that creates a list of hyperlinks to the files i search for. I can click the resulting hyperlink and the PDF opens. I would like to also have it make a copy of the pdf on my C: also without dialog. The source of the files is from the network. FileSearchButton_Click will search a directory for files with the content that match my search string.
aLinkLabel_LinkClicked is where I feel the copy action should be done

Breakes on long a, I can't figure out how to get that Long Tweet ID
Here is the full code
Problem was that my X was not incrementing correctly as it was out of for loop.
int x = 0;
foreach (var t in getTweets)
{
ListViewItem listItem = new ListViewItem(t.Text);
listItem.SubItems.Add(t.CreatedBy.ScreenName.ToString());
listItem.SubItems.Add(t.CreatedAt.ToString());
listItem.SubItems.Add(t.FavoriteCount.ToString());
listItem.SubItems.Add(t.RetweetCount.ToString());
listView1.Items.Add(listItem);
listView1.Items[x].Tag = t.Id;
x = x +1;
}

bm.changevalues("Hello", ft);
pc.print();
}
i need to get the output Hello
You are setting the values you want in a completely different object from the one where you try to use them.
One way to fix this:
Change the PrintClass so that it inherits the BasicMethod class instead of BasicClass
class PrintClass : BasicMethod
Then change your click handler:
private void button1_Click(object sender, EventArgs e)
{
PrintClass pc = new PrintClass();
Font ft = new System.Drawing.Font("Arial", 12.5f);
pc.changevalues("Hello", ft);
pc.print();
}
I am building an app in windows phone 7 where i need to add an event reminder. On clicking a button the reminder should be set. My cs file is:

}
}
}Now when the reminder button is clicked i want the fields utimee, tzone to be set and i get a pop up message "Event reminder added successfully"
I am not getting the idea on how to do this
You can do these steps:
1.get the values from webservice as global variable：
eventDate,location, utimee, tzone, ename,desc.
2.click the reminder button, execute the click method
private void BtnReminderClick(object sender, EventArgs e)
{
RegisterReminder();
}
3.do reminder register
private void RegisterReminder()
{
var reminder = ScheduledActionService.Find(ename) as Reminder ?? new Reminder(ename);
reminder.Title = ename;
reminder.Content = desc;
// parse eventDate,utimee to beginDateTime
reminder.BeginTime = DateTime.Parse(eventDate).Date + DateTime.Parse(utimee).TimeOfDay;
reminder.ExpirationTime = reminder.BeginTime.AddDays(1);
reminder.RecurrenceType = RecurrenceInterval.None;
if (ScheduledActionService.Find(ename) == null)
ScheduledActionService.Add(reminder);
else
ScheduledActionService.Replace(reminder);
MessageBox.Show("reminder set succeed!");
}
