GUI design
*I started with a basic widows form and added a menu strip, 42 buttons in a grid pattern and 5 labels to display game information.
*Next we need to add a File and Help option to the main menu. Under the File option we need a New Game, Reset Scores, and Exit options. Under Help all we need is an About option to show information about the programmer.
*After all of the added options have been named appropriately we double click on the New Game, Reset Scores, Exit, and About options to add click handlers for our menu. Now we are ready to start coding. We also need to double click the form its self in order to create a form load event.
Coding
*First we need to add our references to the very top section of the code. Add the following:
using System.IO; using System.Threading; using Microsoft.VisualBasic;
*We need to add the Visual Basic reference manually. Select Add Reference under Project on the main menu. Scroll down until you find Microsoft.VisualBasic and select ok. This is so we can use a visual basic input box for a user name input when a user gets a high score.
*Now we can declare our class level arrays. We need one integer type array for storing random #’s from our random #’s function, one to store our 42 non-repeating #’s for randomizing pictures, and one to store our 3 high scores. We also need a string type array for the names that go with the high scores.
*Next we need to declare 2 booleen type class level variables. One for keeping track of which guess the user is on. One for keeping track of matches.
*We also need to declare 6 integer type class level variables. We will need 4 to hold values for checking matches and storing button value, one for keeping track of number of guesses left, and one for keeping track of users score.
*We also need to declare a random number object before we start coding our methods
*In our methods section we will need 5 methods plus the ones we already have for our menu and form load. First we need a new game method:
private void newGame()
{
intScore = 0;
bln_isFirst = true;
bln_isMatch = false;
//create bln variable to check if random #'s exist in board array already
bool bln_isSame = false;
//display the score and guesses left
lblGuess.Text = "Trys Left: " + intGuess.ToString();
lblScore.Text = "Score: " + intScore.ToString();
//set high scores arrays from high scores file and display on label
try
{
StreamReader highScoresStreamReader = new StreamReader(Directory.GetCurrentDirectory() + @"\Pictures\HighScores.txt");
while(highScoresStreamReader.Peek() !=-1)
{
for(int a=0; a < 3; a++)
intHighScores[a] = int.Parse(highScoresStreamReader.ReadLine());
}
highScoresStreamReader.Close();
}
catch
{
MessageBox.Show("File Reading Error1");
}
//set user array from user file and display on label
try
{
StreamReader userStreamReader = new StreamReader(Directory.GetCurrentDirectory() + @"\Pictures\User.txt");
while(userStreamReader.Peek() !=-1)
{
for(int a=0; a < 3; a++)
strUser[a] = userStreamReader.ReadLine();
}
userStreamReader.Close();
}
catch
{
MessageBox.Show("File Reading Error1");
}
lblHighScore.Text = "HighScores: "+ strUser[0]+"..."+intHighScores[0];
lblHighScore2.Text = strUser[1]+"..."+intHighScores[1];
lblHighScore3.Text = strUser[2]+"..."+intHighScores[2];
//set number of guesses
intGuess = 13;
//seed the random number function
DateTime dtmCurrent = DateTime.Now;
generateRandom = new Random(dtmCurrent.Millisecond);
_buttonArray = new Button[42] {
btn0, btn1, btn2, btn3, btn4, btn5, btn6, btn7, btn8, btn9,btn10,
btn11, btn12, btn13, btn14, btn15, btn16, btn17, btn18, btn19,
btn20, btn21, btn22, btn23, btn24, btn25, btn26, btn27, btn28,
btn29,btn30, btn31, btn32, btn33, btn34, btn35, btn36, btn37,
btn38, btn39, btn40, btn41};
for (int i = 0; i < 42; i++)
{
//ensure that the event only called once
this._buttonArray[i].Click -= this.ClickHandler;
//set new click handler
this._buttonArray[i].Click += new System.EventHandler(this.ClickHandler);
//enable all buttons and set images to null
_buttonArray[i].Enabled = true;
_buttonArray[i].Image = null;
}
//fill array with random #'s from 1 to 42
int intAdd = 0, intCount1;
for(int r=0; r < 200; r++)
{
intStorage[r] = generateRandom.Next(1,43);
}
for(intCount1=0; intCount1 < 250; intCount1++)
{
bln_isSame = false;
if(intAdd < 43)
{
//check to see if array already contains generated #
foreach(int intBoard1 in intBoard)
{
if(intStorage[intCount1] == intBoard1)
{
bln_isSame = true;
}
}
//fill board array with random non matching #'s
if(bln_isSame == false && intStorage[intCount1] != 0)
{
intBoard[intAdd] = intStorage[intCount1];
intAdd++;
}
}
}
}
*next we need a click handler for our buttons and a button events method
private void ClickHandler(object sender, System.EventArgs e)
{
//button handler...temporarily set button to false visibility and not enabled
Button tempButton = (Button)sender;
intCount4 = (tempButton.TabIndex - 42);
//store last int Count2 for checking match and button use.
intCount3 = intCount2;
//set random number for passing to find file name
intCount2 = intBoard[intCount4];
ImgLocation = checkNumbers(intCount2);
tempButton.Image = Image.FromFile(ImgLocation);
tempButton.Enabled = false;
buttonEvents(tempButton, intCount2, intCount3, intCount4);
//set pause for second turn so player can see pictures
for (int i = 0; i < 10; i++)
{
System.Threading.Thread.Sleep(100);
}
}
private void buttonEvents(Button tempButton, int intCount2, int intCount3, int intCount4)
{
if(bln_isFirst == true)
{
bln_isFirst = false;
intCount5 = intCount4;
}
else
{
bln_isFirst = true;
bln_isMatch = checkMatch(intCount2, intCount3);
// if not a match refresh buttons
if(bln_isMatch == false)
{
tempButton.Enabled = true;
tempButton.Image = null;
_buttonArray[intCount5].Enabled = true;
_buttonArray[intCount5].Image = null;
intGuess -= 1;
}
else
{
intScore += 10;
}
}
if (intGuess <= 0)
{
MessageBox.Show("game over");
for (int r = 0; r < 42; r++)
{
_buttonArray[r].Enabled = false;

if (intScore > intHighScores[0])
{
//move old high scores down one spot
intHighScores[2] = intHighScores[1];
intHighScores[1] = intHighScores[0];
intHighScores[0] = intScore;
//show the User Input Form
strUser[0] = Interaction.InputBox("Congratulations", "New High Score", "Please enter your name:", 10, 10);
}
else if (intScore > intHighScores[1] && intScore <=intHighScores[0])
{
//move middle high score down one spot
intHighScores[2] = intHighScores[1];
intHighScores[1] = intScore;

}
else
{
//display the score and guesses left
lblGuess.Text = "Trys Left: " + intGuess.ToString();
lblScore.Text = "Score: " + intScore.ToString();
}
}
*The final two user added methods will be a checkMatch method to check for matches and a checkNumbers method to translate our random #’s file paths for our pictures.

else
{
//display the score and guesses left

}
}
*finally we will need to define our methods for the menu bar and our form load event
private void mnuNewGame_Click_1(object sender, System.EventArgs e)
{
//call newGame method
newGame();
}
private void mnuResetScore_Click(object sender, System.EventArgs e)
{
//write name string to the user file
StreamWriter NameStreamWriter = new StreamWriter(Directory.GetCurrentDirectory() + @"\Pictures\User.txt", false);
for(int p=0; p<3; p++)
{
NameStreamWriter.WriteLine("NAME");
}
NameStreamWriter.Close();
//write 0 strings to the highscores file
StreamWriter hScoreStreamWriter = new StreamWriter(Directory.GetCurrentDirectory() + @"\Pictures\HighScores.txt",false);
for(int p=0; p<3; p++)
{
hScoreStreamWriter.WriteLine("0");
}
hScoreStreamWriter.Close();
}
private void mnuExit_Click_1(object sender, System.EventArgs e)
{
//close this application
this.Close();
}
private void mnuAbout_Click(object sender, System.EventArgs e)
{
//display 'programmed by' message
MessageBox.Show("Programmed by: Galen Goforth");
}
private void frmMain_Load(object sender, System.EventArgs e)
{
newGame();
}
*and there it is You will need to add the pictures to your /bin/debug folder for your project as well as a high scores and user text file to hold high score information. I have attached a working copy(hopefully). This is my first tutorial so suggestions and criticism are more than welcome. I know I didn't explain everything here but my comments are fairly explanatory.
