help with windows form game

the code is not working for me. i put :
private void button25_Click(object sender, EventArgs e)
{
button21.Visible = true;
button22.Visible = true;
button23.Visible = true;
button24.Visible = true;
button26.Visible = true;
button29.Visible = true;
button30.Visible = true;
button31.Visible = true;
button32.Visible = true;
Label1.Visible = true;
label2.Visible = true;
label3.Visible = true;
pickRandom();
}
for the start button
then i get a little confused. where do i put:
public void hideControls() // hideControls();   // put  inside  Form1()
{
foreach (Control myControl in this.Controls)
{
myControl.Visible = false;
}
button25.Visible = true;// make start button visible
}
do i delete private voide form1_load(object sender, eventargs e) and then put the code??
it is probably simple but the code is not working for me.

frogleg, i wanted to use the start button to show all of the hidden objects on the windows form.
example. when the program starts nothing is visible except the start button, then when the start button is clicked everything else shows; so how would i do that.

try this.
Also under the color column maybe using a label color for correct color may be a better idea
By the way congratulations - you new code is a lot easier to follow.

i redid the whole code and made a windows form but the problem i have is that the reset button does not work properly (button 26).
all of the code for the buttons are the same so i was wondering how i would make a method and call all the buttons instead of having code for each button. the code looks like this
private void button04_Click(object sender, EventArgs e)
{
this.ActiveControl.BackColor = controlColor;
this.ActiveControl.Text = controlNumber;
allCellsClicked[3] = '1';
if (all_Buttons_Clicked())
{
allCellsClicked[0] = '0';
allCellsClicked[1] = '0';
allCellsClicked[2] = '0';
allCellsClicked[3] = '0';
button04.Enabled = false;
button03.Enabled = false;
button02.Enabled = false;
button01.Enabled = false;
guess++;
Label1.Text = "Guess Number " + Convert.ToString(guess);
label4.Visible = true;
label5.Visible = true;
label4.Text = "0";
label5.Text = "0";
if (int.Parse(button01.Text) == fourth ) {label5.Text = Convert.ToString(int.Parse(label5.Text) + 1);}
if (int.Parse(button02.Text) == third ) {label5.Text = Convert.ToString(int.Parse(label5.Text) + 1); }
if (int.Parse(button03.Text) == second) {label5.Text = Convert.ToString(int.Parse(label5.Text) + 1);}
if (int.Parse(button04.Text) == first ) {label5.Text = Convert.ToString(int.Parse(label5.Text) + 1); }
int a = int.Parse(button01.Text), b = int.Parse(button02.Text), c = int.Parse(button03.Text), d = int.Parse(button04.Text);
if (fourth == a || third == a || second == a || first == a) {label4.Text = Convert.ToString(int.Parse(label4.Text) + 1);a = 10;}
if (fourth == b || third == b || second == b || first == b) {label4.Text = Convert.ToString(int.Parse(label4.Text) + 1); b = 10;}
if (fourth == c || third == c || second == c || first == c) {label4.Text = Convert.ToString(int.Parse(label4.Text) + 1);c = 10;}
if (fourth == d || third == d || second == d || first == d) {label4.Text = Convert.ToString(int.Parse(label4.Text) + 1); d = 10;}
label4.Text = Convert.ToString(int.Parse(label4.Text) - int.Parse(label5.Text));
}
}

I am sorry; apparently I was confused. There are so many Color objects that I was confused. The System.Drawing.Color structure does not have any constructors that take arguments.


Note however that "throws an error" implies execution and I assume that the error "does not contain a constructor" occurs when compiling.

darks[0] = new Color(0, 0, 255);  throws an error:
Error 1 'System.Drawing.Color' does not contain a constructor that takes '3' arguments - ,which can be overridden.
the correct way to call it is 
darks[0] = Color.FromArgb(0, 0, 255);
Is this not the way you code it ?
 

Frogleg: what is the problem with "new Color(0, 0, 255)"? Why won't it work? Note that I am not Kel Michael.

I had a look at your project and no way it will work
eg:
darks[0] = new Color(0, 0, 255); // Blue
should be:
darks[0] = Color.FromArgb(0, 0, 255);
is one of many errors
When in designer view- where the form is visible, open the properties windows Form1 and click on the lightening bolt icon at the top
This will show you a list of events that can be performed eg; MouseDown, MouseMove etc
An example of MouseMove
private void Form1_MouseMove(object sender, MouseEventArgs e)
{
//add two labels to form
label1.Text = Convert.ToString(e,X);
label2.Text = Convert.ToString(e,Y);
if (e.Button == MouseButtons.Left)
{
MessageBox.Show("Left mouse clicked");
}
There is also a form paint event where you can use 
private void Form1_Paint(object sender, PaintEventArgs e) //all control have events
{
  e.Graphics.DrawLine(Pens.Red,20,20,100,20);
}
Use the intellisense and also snippets

}
Start a new project using the above methods, and repost for further assistance
By the way Graphics g means nothing without assigning to a bitmap or control (pictureBox, panel etc)

I wish I had time to help you. The question you are asking is the type of thing that is described very well in many books and in many other resources. Unless a member in this community has plenty of time to write something for just you, it will be much more productive for you to benefit from some of the existing resources. I hope there are some articles and tutorials in this web site that will help you.
 
Are you near a library where you can borrow books? Are there books in your school library that you can borrow? Can your parents buy books for you? If any of those are possible then you will get much more help that way.
 
I have a nephew that I tried to teach programming when he was young. It was frustrating for me, since he did not understand the concept of methods and he would not learn. He is an adult now and has a job but he still does not do much programming. I don't know how old you are but whatever your age, you are headed in the right direction.
