    <p>Second post here, so I started my computing course recently and we are working on C# I have understood everything to far and we have our first project that we are supposed to work on, however I have been stumped here, I will show you the entire code for you to read, then I will break away at the bottom to the part which the error is found:</p> <pre><code>using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Threading.Tasks; using System.Windows.Forms; namespace Calculator { public partial class Form1 : Form { string number; public Form1() { InitializeComponent(); } private void textBox1_TextChanged(object sender, EventArgs e) { } private void Form1_Load(object sender, EventArgs e) { } private void Number0_Click(object sender, EventArgs e) { number = number + "0"; CalcForm.Text = number; } private void Number1_Click(object sender, EventArgs e) { number = number + "1"; CalcForm.Text = number; } private void Number2_Click(object sender, EventArgs e) { number = number + "2"; CalcForm.Text = number; } private void Number3_Click(object sender, EventArgs e) { number = number + "3"; CalcForm.Text = number; } private void Number4_Click(object sender, EventArgs e) { number = number + "4"; CalcForm.Text = number; } private void Number5_Click(object sender, EventArgs e) { number = number + "5"; CalcForm.Text = number; } private void Number6_Click(object sender, EventArgs e) { number = number + "6"; CalcForm.Text = number; } private void Number7_Click(object sender, EventArgs e) { number = number + "7"; CalcForm.Text = number; } private void Number8_Click(object sender, EventArgs e) { number = number + "8"; CalcForm.Text = number; } private void Number9_Click(object sender, EventArgs e) { number = number + "9"; CalcForm.Text = number; } private void ButtonDecimal_Click(object sender, EventArgs e) { number = number + "."; CalcForm.Text = number; } private void ButtonTimes_Click(object sender, EventArgs e) { string equation1 = CalcForm.Text; double equation1int = Convert.ToDouble(equation1); CalcForm.Text = ""; number = ""; string equation2 = CalcForm.Text; double equation2int = Convert.ToDouble(equation2); var equalsclicked = ButtonEquals_Click; if (equalsclicked == true) { CalcForm.Text = ""; number = ""; double answer = equation1int * equation2int; string answer1 = Convert.ToString(answer); CalcForm.Text = answer1; } } private void ButtonEquals_Click(object sender, EventArgs e) { } } } </code></pre> <p>So, there is the form code, and here is the error, I will comment on the exact line</p> <pre><code>{ string equation1 = CalcForm.Text; double equation1int = Convert.ToDouble(equation1); CalcForm.Text = ""; number = ""; string equation2 = CalcForm.Text; double equation2int = Convert.ToDouble(equation2); var equalsclicked = ButtonEquals_Click; //Here if (equalsclicked == true) //Here { CalcForm.Text = ""; number = ""; double answer = equation1int * equation2int; string answer1 = Convert.ToString(answer); CalcForm.Text = answer1; } </code></pre> <p>There are the errors, is there anything else that you can see wrong with it? Or optimization wise? This is only for multiplication, but once I have done that, I can easily copy it over, thanks :)</p>

    1. COWhat is the purpose behind this line? `var equalsclicked = ButtonEquals_Click;`. It doesn't really make any sense... you are looking for a true/false result from an event handler that is `void`?

    2. CORight, this is where I am going wrong, what I am aiming is for the if statement to run, when the button Equals is clicked, inside the if statement will be the final calculation.

    3. COTo check if the ButtonEquals was pressed you could check the sender of the event.

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.
