Message Box unable to call local variable

I'm going to preface this by saying I'm sure the question has already been asked but I've tried all the suggestions and nothing seems to work for me. It just keeps returning a blank message box. If the answer were just a nice snippet of code I can add to my answer that would be fantastic.
private string Text1;
public void Button_Click(object sender, RoutedEventArgs e)
{
TextBox txtbx = new TextBox();
txtbx.Height = 50;
txtbx.Width = 200;
txtbx.Margin = new Thickness(771, 282, 0, 0);
txtbx.Background = new SolidColorBrush(Colors.White);
txtbx.Foreground = new SolidColorBrush(Colors.Black);
Text1 = txtbx.Text;
if (EditChecked == true)
{
LayoutRoot.Children.Add(txtbx);
Button Save = new Button();
Save.Height = 25;
Save.Width = 50;
Save.Content = "Save";
Save.Margin = new Thickness(771, 382, 0, 0);
LayoutRoot.Children.Add(Save);
txtbx.Text = Text1;
Save.Click += delegate
{
txtbx.Visibility = Visibility.Collapsed;
Save.Visibility = Visibility.Collapsed;
};
}
else if (ViewChecked == true)
{
MessageBox.Show(Text1);
}
}
Edit: Thanks to mjwills I moved the "Text1 = txtbx.Text;" line so this is what ended up working fyi:
private string Text1;
public void Button_Click(object sender, RoutedEventArgs e)
{
TextBox txtbx = new TextBox();
txtbx.Height = 50;
txtbx.Width = 200;
txtbx.Margin = new Thickness(771, 282, 0, 0);
txtbx.Background = new SolidColorBrush(Colors.White);
txtbx.Foreground = new SolidColorBrush(Colors.Black);
if (EditChecked == true)
{
LayoutRoot.Children.Add(txtbx);
Button Save = new Button();
Save.Height = 25;
Save.Width = 50;
Save.Content = "Save";
Save.Margin = new Thickness(771, 382, 0, 0);
LayoutRoot.Children.Add(Save);
txtbx.Text = Text1;
Save.Click += delegate
{
txtbx.Visibility = Visibility.Collapsed;
Save.Visibility = Visibility.Collapsed;
Text1 = txtbx.Text;
};
}

You declare:
private string Text1;
However you only assign it on the chance:
EditChecked = True
And you only display the message if
EditChecked = False
So, you need to assign Text1 on if the EditChecked = False. Perhaps on the declaration:
private string Text1 = "My default message";

Why when setting the form1.ShowInTaskBar to false it's throwing exception?

I want to start the form in some case in the tray icon.
So in the constructor I did:
public Form1()
{
InitializeComponent();
settingsFileDirectory = Path.GetDirectoryName(Application.LocalUserAppDataPath) +
settingsFileDirectory;
if (!Directory.Exists(settingsFileDirectory))
{
Directory.CreateDirectory(settingsFileDirectory);
}
settingsFile = Path.Combine(settingsFileDirectory,settingsFile);
if (!File.Exists(settingsFile))
{
File.Create(settingsFile);
}
string[] values = System.IO.File.ReadAllText(settingsFile).Split(',');
downloadonstart = Convert.ToBoolean(Convert.ToInt32(values[0]));
loadonstart = Convert.ToBoolean(Convert.ToInt32(values[1]));
startminimized = Convert.ToBoolean(Convert.ToInt32(values[2]));
displaynotifications = Convert.ToBoolean(Convert.ToInt32(values[3]));
lvnf = new ListViewNF();
lvnf.Location = new Point(250, 18);
lvnf.Size = new Size(474, 168);
lvnf.View = View.Details;
this.SuspendLayout();
lvnf.LabelEdit = true;
lvnf.Columns.Add("From", 100, HorizontalAlignment.Left);
lvnf.Columns.Add("Subject", 200);
lvnf.Columns.Add("Date", 300);
lvnf.Sorting = SortOrder.None;
lvnf.ColumnClick += lvnf_ColumnClick;
lvnf.Click += lvnf_Click;
this.Controls.Add(lvnf);
this.ResumeLayout(false);
label8.Visible = false;
pbt.Size = new Size(216, 10);
pbt.Location = new Point(8, 330);
pbt1.Size = new Size(396, 10);
pbt1.Location = new Point(250, 198);
this.Controls.Add(pbt1);
groupBox1.Controls.Add(pbt);
pbt.Text = "0%";
pbt1.Text = "0%";
//LoadFullMessages();
if (startminimized == true)
{
this.WindowState = FormWindowState.Minimized;
}
if (loadonstart == true)
{
backgroundWorker2.RunWorkerAsync();
}
if (downloadonstart == true)
{
backgroundWorker1.RunWorkerAsync();
}
}
Then inside the Form1_Resize event I did this:
private void Form1_Resize(object sender, EventArgs e)
{
if (this.WindowState == FormWindowState.Minimized)
{
this.Hide();
this.ShowInTaskbar = false;
}
}
What makes the exception is the line:
this.ShowInTaskbar = false;
An unhandled exception of type 'System.StackOverflowException' occurred in System.Windows.Forms.dll
Then I click on break and I see this:
What am I doing wrong?

WPF Mediaelement.Position is not working

What I need is to set the Position property on WPF's MediaElement control. But when I play the video, (either via Play() or through some kind of animation on Opacity) it is is not working at all. It is showing 00:00:00 time, but I would expect it to be set to 00:00:05.
I have hard-coded Position value and it is not working at all.
Just In case I am going to put all my code I have so u can see the whole animation logic.
Any clue?
public partial class CrossFadeTransition : UserControl

DoubleAnimation _doubleAnimationFrontPlayer = new DoubleAnimation();
DoubleAnimation _doubleAnimationBackPlayer = new DoubleAnimation();

positionPlayer2 = PlayerPosition["Player2"];
if (positionPlayer1 == Library.Position2D.Back)
{

}

{

}
if (positionPlayer2 == Position2D.Front)
{

_doubleAnimationBackPlayer.To = 0;
_doubleAnimationBackPlayer.Duration = new Duration(Duration);
PlayerPosition["Player2"] = Position2D.Back;
}

{
_doubleAnimationBackPlayer.From = 0;
_doubleAnimationBackPlayer.To = 1;
_doubleAnimationBackPlayer.Duration = new Duration(Duration);
PlayerPosition["Player2"] = Position2D.Front;
}
_sb1.Children.Add(_doubleAnimationFrontPlayer);
Storyboard.SetTargetProperty(_doubleAnimationFrontPlayer, new PropertyPath("(Panel.Opacity)"));
Storyboard.SetTarget(_doubleAnimationFrontPlayer, Player1);
_sb1.Completed += _sb1_Completed;
_sb1.Begin();
//
_sb2.Children.Add(_doubleAnimationBackPlayer);
Storyboard.SetTargetProperty(_doubleAnimationBackPlayer, new PropertyPath("(Panel.Opacity)"));
Storyboard.SetTarget(_doubleAnimationBackPlayer, Player2);
_sb2.Completed += _sb2_Completed;
_sb2.Begin();
}
catch (Exception)
{
throw;
}
}
void _sb2_Completed(object sender, EventArgs e)
{
_sb2.Completed -= _sb2_Completed;
Debug.WriteLine("Player2 COMPLETED " + DateTime.Now.TimeOfDay);
if (positionPlayer2 == Position2D.Front)
{
Player2.Stop();
}
}
void _sb1_Completed(object sender, EventArgs e)
{
_sb1.Completed -= _sb1_Completed;
Debug.WriteLine("Player1 COMPLETED " + DateTime.Now.TimeOfDay);
if (positionPlayer1 == Position2D.Front)
{
Player1.Stop();
}
}
}
I have tried to do like
Player2.Play();
Player2.Pause();
Player2.Position = TimeSpan.FromSeconds(5); // IT IS NOT WORKING !!!
Player2.Play();
But no joy...

I found some solution. It is not completely ideal because sometimes it shows the first video frame, but at least it is working.
We need those events where we can apply new Position.
void Player2_MediaOpened(object sender, RoutedEventArgs e)
{
Player2.Position = new TimeSpan(0, 0, 7);
}
void Player1_MediaOpened(object sender, RoutedEventArgs e)
{
Player1.Position = new TimeSpan(0, 0, 7);
}
We have to close Mediaelement like this.
Player1.Stop();
Player1.Close();
Player1.Source = uri;
Player1.Play();
Have fun! (beer)

MediaElement freezes video

I apply some LinearGradientBrush animation to MediaElement and after this video is freezing.
I try to reset it via Player1.OpacityMask = null; but no joy.
By the way if I animate Opacity of the MediaElement then video shows good as usually.
Any clue what's up? How to fix the video freezing after applying LinearGradientBrush animation to MediaElement ?
Thank you!

Require help in C# Need to implement moving picture box

I need a help on this,
There are 3 picture boxes, red should grow its Width to left, green should grow its height to top blue's width to right
also if one reaches the top border / any text boxes it should give an error / stop execution
I need to add more picture boxes in future and if two of them collides it should give an error / stop execution. I have managed to code them to go up, however unable to get other functions working. Please some one help me with this.
