How to solve this?

hazel1001 — Wed, 01 Apr 2009 07:50:29 +0800

Hi, im doing my fyp project.
Im facing a problem in programming C#.

Below is a method where to combine 2 numbers together.
For example, i have number "2" and "4" separately at first.

After the method below, i combine the "2 and " 4" to become "24".
After the method and other processes, i need to split the "24" to become "2 -> 4" and display "2 -> 4" .
I have to split the number into 2 and add "->".

I have written the split method..
However, when i have the number "289" and "399".
when i combine together, "289399", it split wrongly.
It become "2" and "89399".
How can i solve this problem??

If when i combine "289" and "399" become "289:399" and separate (":"), it have many problems.
My program have to change many many things and many many many errors happen..since this process related to others..
Anyone can help me?? Really critical moment..

private List<int> itemAB(int[][] newData)
{
String str = "";
//List<int> ab = new List<int>();

for (int i = 0; i < newData.Length; i++)
{
for (int j = 0; j < newData[i].Length - 1; j++)
{

if (j != newData[i].Length)
{
for (int k = j + 1; k < newData[i].Length; k++)
{
//newData = newData.ToString().Split(':');
str = newData[i][j] + "" + newData[i][k];
ab.Add(Convert.ToInt32(str));

}
}

}

}

return ab;
}

//xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

private String strSplit(int num)
{
String str = "" + num;
String str2 = "";
// String[] s = str.Split();
//str2 = s[0] + s[1];

str2 += str.Substring(0, 1);
str2 += " -> " + str.Substring(1);
return str2;
}

split string

hazel1001 — Sun, 29 Mar 2009 23:33:45 +0800

Hi, im having a problem.
for example, i keep 21 in a list.
then i want to split 21 to 2 and 1.
str2 can show "2".
however, str3 unable to show 1. and it show "".
Can anybody help me to solve this??

private String strSplit1(int num)
{
String str = "" + num;
String str2 = "";
str2 += str.Substring(0, 1);

String str1 = "" + num;
String str3 = "";
str3 += str1.Substring(1);
//str2 += " -> " + str.Substring(1);
return str2;
}

Need Help! How to solve this?/

i have a set of sample data.
2 1 5
2 4
2 3
2 1 4
3 1
2 3
3 1
2 3 1 5
2 3 1

item frequency
1 6
2 7
3 6
4 2
5 2

the first thing i did is user only need to insert min support. (support = frequency)

then a tree will come out based on the data above.

Now, the user need to insert minsupport and maxsupport in the LP-tree tab to find out the range and generate a tree view.

i modify the code "for (int x = 0; x < a.Count && b[x] >= support; x++)" to become "for (int x = 0; x < a.Count && b[x] >= minsupport && b[x] <= maxsupport; x++) "

when i insert minsupport = 1 and maxsupport = 4, and click button generate LP-tree (button7)the tree dun have value.
the result should be have the value 4 and 5.

however, the tree view only come out with value when the maxsupport does not less than the support of the highest frequency item, that is item2, frequency7.
if i insert 3 as min support and 7 as maxsupport, the tree view is correct.

may i know what is my problem?
and how to fix it?

problem with timer

hazel1001 — Sun, 15 Mar 2009 01:02:54 +0800

I have a problem when i try to add a timer to my program.
the timer should function as it will start with 00:00:00 when i click button1 and stop when click button3.
however, i found that the timer i did it cant be start with 00:00:00.
It continue count from the time i click button3 after i click button1 again.
Even i close the program and run again, the value in timer cannot be cleared..

How can i set the timer as 00:00:00 or clear the previous value as i click button1?

below is the codes where the timer function:

Timer Clock;
string TimeInString = "";

public Form1()
{
InitializeComponent();
Clock = new Timer();
Clock.Interval=1000;
Clock.Tick+=new EventHandler(Timer_Tick);

this.Controls.Add(textBox3);
textBox3.BackColor = Color.Black;
textBox3.ForeColor = Color.Red;
textBox3.Font = new Font("Trebuchet MS", 10);
textBox3.Text = GetTime();
}

public string GetTime()
{

int hour=DateTime.Now.Hour;
int min=DateTime.Now.Minute;
int sec=DateTime.Now.Second;

TimeInString=(hour < 10)?"0" + hour.ToString() :hour.ToString();
TimeInString+=":" + ((min<10)?"0" + min.ToString() :min.ToString());
TimeInString+=":" + ((sec<10)?"0" + sec.ToString() :sec.ToString());
return TimeInString;
}

public void Timer_Tick(object sender,EventArgs eArgs)
{
if(sender==Clock)
{
textBox3.Text = GetTime();
}
}

private void button1_Click(object sender, EventArgs e)
{
//Click button Open File

Clock.Dispose();
Clock.Start();
textBox1.Clear();
textBox2.Clear();
dataGridView1.Rows.Clear();
......
......
......

}

private void button3_Click(object sender, EventArgs e)
{
tabControl1.SelectTab(2);
button3.Enabled = false;
//button6.Enabled = true;
showTable();
Clock.Stop();
}

Hope anyone can help me solve this..
Thanks..

How to solve this problem?

hazel1001 — Sun, 08 Mar 2009 23:53:34 +0800

I'm doing my final year project. But I'm facing some problems.
In the codes below, no error. but the output expected was wrong.
I have read through many times but unable to recognize where is the mistake.

The sample data i try to run this program as below:
2 1 5
2 4
2 3
2 1 4
3 1
2 3
3 1
2 3 1 5
2 3 1

The output i got is

"Association rules | Support(AB) | Support(A) | Confidence | Confidence(%) | BN Value(%)
2 -> 1 | 4/0 | 7/0 | 4/7 | 57.14 | 56.25
2 -> 3 | 4/0 | 7/0 | 4/7 | 57.14 | 56.25
1 -> 3 | 4/0 | 6/0 | 4/6 | 66.67 | 64.29
2 -> 4 | 2/0 | 7/0 | 2/7 | 28.57 | 31.25"

The output expected should be:

"Association rules | Support(AB) | Support(A) | Confidence | Confidence(%) | BN Value(%)
2 -> 1 | 4/9 | 7/9 | 4/7 | 57.14 | 56.25
2 -> 3 | 4/9 | 7/9 | 4/7 | 57.14 | 56.25
1 -> 3 | 4/9 | 6/9 | 4/6 | 66.67 | 64.29
2 -> 4 | 2/9 | 7/9 | 2/7 | 28.57 | 31.25"

I hope anyone can help me read through these codes and help me discover where i did wrongly..
Thank you so much.

build FP- tree using C#

hazel1001 — Tue, 17 Feb 2009 11:59:16 +0800

I need help from anyone who expert in C#..

Firstly, i have a set of data in text file.
For example,
1 2 5
4 2
2 3
1 2 4
1 3
2 3
1 3
2 3 5 1
1 2 3

I have to read and count the frequency of each item.
Example result,
item freq
1 6
2 7
3 6
4 2
5 2

After that, e.g. '2' have the frequency of 7, i have to sort each item in each row from highest frequency to lowest.
Example result,
2 1 5
2 4
2 3
2 1 4
3 1
2 3
3 1
2 3 1 5
2 3 1

then, i will request user to enter value support.
for example, user enter 3.
the frequency item less than 3 will be eliminated.

and then a tree structure based on the itemset have to be shown.

Im a newbie in C#.
Hope anyone can kindly help me to solve this problem..
