Public Class Form1
Inherits System.Windows.Forms.Form
Private name As String

End Function

Public Function showvalue()
    textbox1.Text() = name
    textbox2.Text() = gpa
End Function

Public Class MyClass
Dim s1 As New Form1
s1.assignvalue()
s1.showvalue()
End Class
End Class

Hi all, I am trying to develop a text mining engine and in it i need to work on large number of files...and deal with lots of words... i ve made a word class which has following variables

public string term;
public int df;
public ArrayList tf = new ArrayList();
public ArrayList docID= new ArrayList();
public static int count;

here term is the variable wich contains the actual value of the word. now when user queries for a word i need to search all these terms and find out whether the term user wants exists or not.... i ve this word class sorted w.r.t the "term" variable so it means that i can apply binary search for finding the user query.....i m doing this by adding all the term variables of the class in an arraylist and then applying binary search over it....but the problem is that i need to know the index of the arraylist where the user's queried term exists.....and i dont know the way to find out the index :( i ve added the sample chunk of code here.....anyone plzz help

//adding all the term variables of Terminology class to the allTerms ArrayList.......
for(int i = 0; i < Terminology .count; i ++ )
{
allTerms.Add(word[i].term);
}

//queryList is the ArrayList that contains the pharase queried by the user in the form of //one string at one index
for(int j = 0; j < queryList.Count; j ++)
{
if(allTerms.BinarySearch(queryList[j]) >= 0)
{
need to know the index of allTerms ArrayList.
}
}

looking forward for help Regards,

hahahaha well i already knew that but i really needed it :( so i thought y not just give it a try...anyways have fun byee

if (word[j] == null) MessageBox.Show("word array at index " + j + " is null");

Sir it is showing entire array of word as null.....but it works perfectly fine without sorting..........how can all the values changed to null??

public class Terminology : IComparable
{
private string term;
private int df;
private int qTf;
private double qWeight;
private ArrayList tf = new ArrayList();
private ArrayList position= new ArrayList();
private ArrayList docID= new ArrayList();
private static int Count;

    public int CompareTo(object obj)
{
	Terminology w = (Terminology) obj;
	return( w.term.CompareTo( w.term ));
}

//only method in this class other than properties and constructors
public void incDF()
{
df++;
}
}

now moving to TextMiner class

public class TextMiner : System.Windows.Forms.Form , IComparable
{
const int WORDS = 20000;
public Terminology[] word = new Terminology[WORDS];
public void Indexer()
{
Array.Sort(word);
}
private string strValue = "term";
public int CompareTo(object obj)
{
Terminology w = (Terminology) obj;
return( strValue.CompareTo( w.term ));
}
}

it gives this exception An unhandled exception of type 'System.NullReferenceException' occurred in 2ndAssignment.exe Additional information: Object reference not set to an instance of an object. and on this statement

for(int j = 0; j < Terminology.count-1; j++)
{
sw.Write(j+1 +"\t"+word[j].term.PadRight(20,' '));
}

and the exceptions comes when the value of j is 0....m really confused :( looking forward for help Regards, -- modified at 5:43 Wednesday 24th May, 2006

well the exception doesnt come during sorting it comes after the sorting the statement i m cofused about is the use of private string strValue = "term"; isnt there any error in this statement?? i mean term is the variable of terminology class and i m declaring it as a string value in TextMiner class how will this work??

sir it also didnt work :( i ve written the same code in the CompareTo function which i ve written in TextMiner class but it made no difference again same exception :( is there any way out of this ?? looking forward for help Regards,

word = Array.Sort(word, new WordComparer());

well i ve tried this already but it gives compile time error that cant covert type void to type TextMiner.Terminology[] :(
