C# - Why is my form minimizing when playing 2 sounds?

I have a issue : I have a main form who plays music when loaded : and I made a function who plays a sound when a button is pressed : the next form is minimized and their content too (from config.cs to every form), it's supposed to be at fullscreen and I want to keep it fullscreen and not minimized when playing a sound.

The problem is you creating a new thread, and the Program process switches to the second thread.
How to solve: Create one object of MediaPlayer, and switch a song, when you need.
Or: Create two separated MediaPlayers and pause one when you need.

Visual Studio Designer Cannot open a file Despite it being the first and only Class in the file

Whereas MSDN suggests that some incompatible behavior might also cause this issue
In my case, The incompatible behavior is caused by some possibly weird(messed up mappings) on Entity Framework.
I have done due diligence to ensure one-to-one correspondence between the data model and the EF model(even recreated it twice, ground up)
The project builds and runs when I comment out a certain section of code.
public partial class TestForm : SecureForm
{
private myEntities _db = new myEntities();
public TestForm()
{
InitializeComponent();
PopulateTestsList();
}
private void PopulateTestsList()
{
listViewTypes.Items.Clear();
var query = from q in _db.Types orderby q.TypeName select q;
foreach (Type dt in query)
{
ListViewItem lvi = new ListViewItem(new string[]
{
dt.TypeName
});
lvi.Tag = dt;
listViewTypes.Items.Add(lvi);
}
}
private void buttonAdd_Click(object sender, EventArgs e)
{
TestEditForm myEditForm = new TestEditForm(_db);
if (myEditForm.ShowDialog() == System.Windows.Forms.DialogResult.OK)
PopulateTestsList();
}
private void buttonEdit_Click(object sender, EventArgs e)
{
if (listViewTypes.SelectedItems.Count > 0)
{
Test tsdt = listViewTypes.SelectedItems[0].Tag as Test;
if (myEditForm != null)
{
TestEditForm myEditForm = new TestEditForm(_db, mysForm);
if (myEditForm.ShowDialog() == System.Windows.Forms.DialogResult.OK)
PopulateTestsList();
}
}
}
}

Code analysis shows that the form is missing,(MSBuild does not). MSBUILD compiles the form into an exe thats kinda defunct(on the broken entity)
The entity in question has Name & ID properties. Both Name and ID are mapped properly, The collection is pluralized and loaded into a list.

How to bind data to a custom Windows Form using SplitContainer?

I've created a form that I call a ListChooser. It looks like so:
It consists of a System.Windows.Forms.Button and .TextBox.
Clicking on the Button (shown above with the text "Fruits") causes a dialog to popup and some selections are made and the TextBox is populated, like so:
My problem is I can't figure out how to set a System.Windows.Forms.Binding to this TextBox. I think the complication is that it's not just a TextBox, it's 2 components in one. (I know how to data bind with just a standalone TextBox). If I go to the TextBox > Properties > DataBindings > Advanced > ..., All entries listed under Property are not selectable:
I've tried this which has no effect:
private System.Windows.Forms.BindingSource myBindingSource;
this.myBindingSource = new System.Windows.Forms.BindingSource(this.components);
this.myBindingSource.DataSource = typeof(Foods) // Fruits is a Property of Foods;
myListChooser.DataBindings.Add(new System.Windows.Forms.Binding("Text", this.myBindingSource, "Fruits", true));
How do I do this?

How to access text button outside Form.cs class (I mean in Program.cs)

I have created a Form in c# windows. My form contains a button and a text box and it 's name is textbox2 here and it contains code like this in Form1.Designer.cs :
this.textBox2.Location = new System.Drawing.Point(683, 14);
this.textBox2.Name = "textBox2";
this.textBox2.Size = new System.Drawing.Size(100, 20);
this.textBox2.TabIndex = 22;
Now i have created another class called Programss.cs which will do some task and as the task finished i want to print on my form something like this:
textBox2.txt= "Task finished"; //it should print on the textbox of my Form1.cs
How to access this textBox2(which can only be accessed currently in Form1.Designer.cs) in Programss.cs and my other classes ?
EDIT: After Philip Stuyck's comments:
Here is my Form1.cs code :
namespace S
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
}
//please see here
public string TextMessage
{
get { return textBox3.Text; }
set { textBox3.Text = value; }
}
private void btnStart_Click(object sender, EventArgs e)
{
btnStart.Enabled = false;
// StartServer();
}
private void btnClose_Click(object sender, EventArgs e)
{
}
}
}
And Program.cs is :
namespace Senter code here
{
class Program
{
/// <summary>
/// The main entry point for the application.
/// </summary>

{
Application.EnableVisualStyles();

/////////////////////////////////////////////////////////////////////////////////////
// OtherImportantClasses.Programs prgms = new OtherImportantClasses.Programs();
Form1 theForm = new Form1();
theForm.TextMessage = "Task finished";
}
}
}

It dont give any error but it do not print anything in textBox3 .
NOTE: Please note that first i run the winform code i click a button and when i click the button some proccess will run which will further print the text in the textbox. (I feel like my textmessage is not intialized by my message passed to it).

Make sure that textBox2 is public.(can be done in the designer)
Keep a reference to Form1 when you create it and access textBox2 via that reference.
Form1 theForm = new Form1();
... //do stuff
theForm.textBox2.Text = "Task finished";
This is not the most elegant approach to this, but it should work.
An alternative is like this :
public partial class Form1{
public string TextMessage{
get{
return textBox2.Text;
}
set{
textBox2.Text = value;
}
}
}
and in program.cs
Form1 theForm = new Form1();
... //do stuff
theForm.TextMessage = "Task finished";
your code will not work because
Form1 theForm = new Form1();
theForm.TextMessage = "Task finished";
is never executed.
Application.Run(new Form1());
returns only when the form is closed and then the application will end.
Following will work:
Form1 theForm = new Form1();
theForm.TextMessage = "Task finished";
Application.Run(theForm);
But I have the feeling you don't quite understand the framework.
Application.run, will make your application enter into a message loop which makes the application receive window messages.

One way you could do this is to have a method accessible in your Form1 that sets the textBox name to whatever you want. For instance:
public static void SetText (string message)
{
TextBox2.Text = message;
}
You would then call this from your Program.cs class:
Form1.SetText("Whatever text you want the text on the Form1 - TextBox2 to say");
This is the poor man's way of changing the text. There is a more detailed explanation on this other post if you need more details.

As I understood you want to print end result on textBox2.txt textbox, right? So you want to execute some methods on Programss.cs and once execution is finished you want to show "Task finished" on textBox2.txt.
If I am not wrong, what you have to do is return a value from a method from Programss.cs class. You have to call this method from Form1.Designer.cs class. Based on return value you can do whatever you want.
Hope this will be helpful.

You are creating two separate forms, setting text on the second, and expecting it to appear on the first.
Do this:
Form1 theForm = new Form1();
theForm.TextMessage = "Task finished";
Application.Run(theForm);

The errors state that some variables were undeclared or unassigned. As an example, the variable "enrollFromFilePanel" is said to be undeclared but it was created with the line "private EnrollFromFile enrollFromFilePanel;". I am sorry that I cannot provide an sscce and I hope that the solution is something simple. Thank you.
