i have a requirement like i need to filter out the distinct values from an array to another array.
Dim str As String
For Each str In all
If (Not all2.contains(str)) Then
all2.Add(str)
End If
Next
i tried the above logic to get the distinct list but it is telling contains and Add are not the members of system.array?
I have a database which need to be assigned into array arr()(), e.g.
arr(0)(0) = aa arr(1)(0) = ab arr(2)(0) = aa
arr(0)(1) = bb arr(1)(1) = ba arr(2)(1) = ba
arr(0)(2) = cc arr(1)(2) = cc arr(2)(2) = cc
I need to find distinct / unique value in each arr(k)(0), arr(k)(1), arr(k)(2); where k=0..2. Then i need to insert the result into array cat as follows:
cat(0)(0) = {aa} cat(0)(1) = {ab}
cat(1)(0) = {bb} cat(1)(1) = {ba}
cat(2)(0) = {cc}
I've tried code below but it doesn't work. The assigning process into array arr()() from DB is OK. Problem only come up if I try to find the distinct value (If Not (cat(j).Contains(ds.Tables(0).Rows(i).Item(j))) ... End If).
For i = 0 To 2
list(i) = New Integer(3) {}
For j = 0 To 2

I feel quite silly asking this, but I couldn't find a definite answer anywhere. in vb.net, how are the array elements defined (if they are defined) for, for example:

View 6 RepliesI have a program that reads in lottery results from the past 6 months (from the national lottery site) from a text file
31-Mar-2010,29,18,38,44,14,43,13,3,GUINEVERE
27-Mar-2010,32,38,11,15,42,6,24,2,GUINEVERE
24-Mar-2010,3,49,28,5,23,42,41,4,GUINEVERE
and stores it in an array (n-1,6) where n is the number of lottery lines, so the array looks like
0 1 2 3 4 5 6
0 29 18 38 44 14 43 13
1 32 38 11 15 42 6 24
then, in a 1D array I store the player's numbers, simply as
0 23
1 16
2 19
[code]....
I want it to take each number from the player's number array individually and compare them to each row individually in the lotto results array i.e. the first six cells in each row in the results array will be compared with each user number to find any matches, if a value matches then a count is incremented. if the count is greater than 2 but i'm getting no where with it :( i've been trying to use the For To loops but keep getting index out of range, or else nothing is happening at all!

I'm having some trouble extracting a distinct value out of a dataset.. I have a database table with 5 fields,
ProjectName, VendorName, ExpenseType; TxnDate; Amount
In VB6 I would have several different recordsets opened one after another to
A. Find all the unique project names within the table (and put them into a For/Next loop)
B. For each unique project name open a recordset to look up unique vendor names applicable to it (add For/Next)
C. For each unique projname, unique vend combination find unique exptype....for next loop....
D. For each unique projname, vendor name, exptype, date combination, sum up the dollar amounts...
The end effect is that you have a net dollar amount for each unique combination of project/vendor/expensetype/date.I dont like doing it like this because I have to keep hitting the database, I wanted to know if there was something I could do within the actual dataset which will be filled when I open the application with the values of the entire table..I got to ds.tables("Text").select.distinct( ....not sure how to proceed and everthing I've read online leads me into a complicated direction of creating new datatables...

View 6 Repliescast integer values to an array of enum values?
View 2 RepliesI have a text box that a user can enter integer values. When the user clicks the button, I want the value to be stored in an array. It works for the first value, but when the user enters the second value and clicks the button, the first value then becomes the index number of the element that stores the value, which is bigger than the array. I don't understand why the array index isn't incrementing by 1, and why/how the user entered value is assigned to "number".
For example:
100 -> click -> array(0) = 100 'Correct
200 -> click -> array(100) 'Out of bounds
