I'm new to this programming arena so I'll be short, I'm teaching myself C# and I'm trying to learn how to have integers from a user's input into a textbox get calculated from a button1_Click to appear on the form. Yes, this is a class assignment but I think I have a good handle on some of this but not all of it; that's why I'm turning to you guys. Thanks for all of the advice guys.</p> <p>I'm using Microsoft Visual Studio 2010 in C# language. I'm using Windows Forms Application and I need to create a GUI that allows a user to enter in 10 integer values that will be stored in an array called from a button_Click object. These values will display the highest and lowest values that the user inputted. The only thing is that the array must be declared above the Click() method.</p> <p>This is what I have come up with so far:</p> <pre><code>namespace SmallAndLargeGUI { public partial class Form1 : Form { public Form1() { InitializeComponent(); } public void inputText_TextChanged(object sender, EventArgs e) { this.Text = inputText.Text; } public void submitButton_Click(object sender, EventArgs e) { int userValue; if(int.TryParse(inputText.Text, out userValue)) { } else { MessageBox.Show("Please enter a valid integer into the text box."); } int x; x = Convert.x.ToString(); int squaredResults = squared(x); int cubedResults = cubed(x); squared(x); squaredLabel.Text = x.ToString() + " squared is " + squaredResults.ToString(); cubedLabel.Text = x.ToString() + " cubed is " + cubedResults.ToString(); } public static int squared(int x) { x = x * x; return x; } public static int cubed(int x) { x = x * squared(x); return x; } } } </code></pre> <p>Now I can't run this program because line 38 shows an error message of: 'System.Convert' does not contain a definition for 'x' Also I still have to have an array that holds 10 integers from a textbox and is declared above the Click() method. Please guys, any help for me? This was due yesterday.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
