Nice. I wasn't aware of it.

Hi,
If your question was not specifically about environment variables but instead about the directory containing the common language runtime then take a look at the System.Runtime.InteropServices.RuntimeEnvironment class.
The GetRunTimeDirectory method may be what you want.

Hi,
I'm new with C# and I have a little problem.
I'm trying to make button and when the user clicks the button,
textbox shows message "This works!"
However, nothing happens when the button is pressed down.
Could you please help me?
The code is listed below.
using System;
using System.Drawing;
using System.Collections;
using System.ComponentModel;
using System.Windows.Forms;
using System.Data;
namespace WindowsApplication2
{
/// <summary>

/// </summary>
private System.ComponentModel.Container components = null;
public Form1()
{
//

//
InitializeComponent();
//
// TODO: Add any constructor code after InitializeComponent call
//
}
private void NaytaTeksti_Click(object sender, EventArgs e)
{
string text = "This works!";
textBox1.Text = text;
}
/// <summary>

{

{
components.Dispose();
}
}
base.Dispose( disposing );
}

{
this.NaytaTeksti = new System.Windows.Forms.Button();
this.textBox1 = new System.Windows.Forms.TextBox();
this.SuspendLayout();
//

//
this.NaytaTeksti.Location = new System.Drawing.Point(80, 88);
this.NaytaTeksti.Name = "NaytaTeksti";
this.NaytaTeksti.Size = new System.Drawing.Size(128, 23);
this.NaytaTeksti.TabIndex = 0;
this.NaytaTeksti.Text = "Nayta";
//

//
this.textBox1.Location = new System.Drawing.Point(96, 120);
this.textBox1.Name = "textBox1";
this.textBox1.TabIndex = 1;
this.textBox1.Text = "";
//
// Form1
//
this.AutoScaleBaseSize = new System.Drawing.Size(5, 13);
this.ClientSize = new System.Drawing.Size(292, 273);
this.Controls.Add(this.textBox1);
this.Controls.Add(this.NaytaTeksti);
this.Name = "Form1";
this.Text = "Form1";
this.ResumeLayout(false);
}
#endregion

}
}
}

Hi,
you have to add the following line into your InitializeComponent Method
this.NaytaTeksti.Click += new System.EventHandler(this.NaytaTeksti_Click);
otherwise your Event Handler is never called.
Regards,
Jens

Hi,
As JF2015 said, there is a line missing.
However, when using Visual Studio, you are not supposed to edit tje InitializeComponent() method, it is generated and managed by Visual Designer.
So either use the Visual Designer to add a click event to your button, or add the new line to your Form1 constructor, right after the call to InitializeComponent().

kiddo…… NaytaTeksti_Click(object sender, EventArgs e)
this event dosn't belong to any Control
here:
this.NaytaTeksti.Location = new System.Drawing.Point(80, 88);
this.NaytaTeksti.Name = "NaytaTeksti";
this.NaytaTeksti.Size = new System.Drawing.Size(128, 23);
this.NaytaTeksti.TabIndex = 0;
this.NaytaTeksti.Text = "Nayta";
this.NaytaTeksti.Click+=new System.EventHandler(this.NaytaTeksti_Click);//please add this

Hi! Is there a way to acquire the letters from the grid of this game:(it is in Bulgarian)
The game is:http://bezumie.com/dumino/[^]
In the text field you write a player name. Then you click the button next to it - "ВХОД". When the page loads there is a grid, which eventually fills with Cyrillic characters. How can I get the characters with a C# application???
Via Firefox I saw the page source. There is a board array which contains the characters. But I don't know how to access the information with my program.
Still learning...

well, this is bad idea to do this on sites...but a little hint, that input element id is 'fld'.

no, there is no property exists in TreeView to hide a node but you can remove a node.

Just because you need the nodes hidden doesn't mean that you can do it - you may need to investigate a third party control to see if you can find this feature there.

Another possible solution is to handle the OnBeforeSelect event of the TreeView. Check the Node passed in the TreeViewCancelEventArgs and if it is one that you would like disabled, use the Cancel property from the TreeViewCancelEventArgs to stop user interaction. Of course it might be polite to give the user a notification for the reason.
Alternatively combine the above, without the user notification, with drawing the nodes that should be disabled yourself in a dimmed-out style.
Investigate the DrawMode property of the TreeView to find out how.

You're trying to put an array of them in; you can't do that with Add.
You could use a foreach loop to add them; that also allows you to verify that they're not null and such.

Not guide you, but I can suggest two starting points for your research;
