What can l do? Whenever I want to compile I get the above mention error.
Do I have to add any library?

I am building a vending machine and I am stuck on adding coins.

this.Hide();
}
private void fiveP_Click(object sender, EventArgs e)
{
balance.Text = ((double)balance.Text + 0.05).ToString();
}
private void tenP_Click(object sender, EventArgs e)
{
balance.Clear();
balance.Text = balance.Text + "0.10";
}
private void twentyP_Click(object sender, EventArgs e)
{
balance.Clear();
balance.Text = balance.Text + "0.20";
}
private void fiftyP_Click(object sender, EventArgs e)
{

balance.Text = balance.Text + "0.50";
}

if balance is the textbox you are working with, you are clearing it with the button press, erasing whatever was in it prior to the button press, so it will always be "" + whatever. also, you can't add strings like that, "1.00" + "2.00" == "1.002.00", != "3.00"
You are adding strings rather than numbers. You'll need to convert your strings into numbers to add them together, and you shouldn't clear your results first.
For example:
private void fiveP_Click(object sender, EventArgs e)
{
// balance.Clear(); <- You don't need this.
balance.Text = ((double)balance.Text + 0.05).ToString();
}
that is because you are using a string type for calculating.. there is a difference between calculating something and displaying it. in short:
float value = 0;
void print()
{
balance.Text = string.Format("{0:0.00}", value);
}
private void fiveP_Click(object sender, EventArgs e)
{
value += 0.05f;
print();
}
private void tenP_Click(object sender, EventArgs e)
{
value += 0.10f;
print();
}
private void twentyP_Click(object sender, EventArgs e)
{
value += 0.20f;
print();
}
private void fiftyP_Click(object sender, EventArgs e)
{
value += 0.50f;
print();
}
private void onePound_Click(object sender, EventArgs e)
{
value += 1;
print();
}
private void twoPound_Click(object sender, EventArgs e)
{
value += 2;
print();
}
in your code you are not adding numbers, example:
you have this code:
private void tenP_Click(object sender, EventArgs e)
{
balance.Clear();
balance.Text = balance.Text + "0.10";
}
the value of balance.Text = "0.10"
then, if the next code is executed:
private void fiftyP_Click(object sender, EventArgs e)
{
balance.Clear();
balance.Text = balance.Text + "0.50";
}
the value of balance.Text = "0.50"
the point is that your are trying to add strings not numbers and you are clearing your previous value

It runs the procedure CheckResults 3 times on the aspx page when I only need it to run once.

What have I done wrong to make this happen please as it should only run once.
