How To Find Repeated Values In One Dimensional Array And Change The Values
Jul 14, 2009
I am using Visual Basic express edition 2008.I am trying to know if a value in a single dimensional array is repeated in the array. If yes, then multiply one of them by 100. For example:
MyArray (14) = 12, 15, 18, 15, 18, 11, 15, 18, 16, 14, 18, 8, 12, 17, 10
In the above example:
MyArray (1) = MyArray (3) = MyArray (6) = 15
MyArray (2) = MyArray (4) = MyArray (7) = MyArray (10) = 18
MyArray (0) = MyArray (12) = 12

Is there a way in LINQ to Entities (SQL) to identify all records where a specified word is repeated at least/less than a specified number of times?
I can do this in memory, looking for at least 3 instances of the word "word" using:
Where(Function(x) x.Description.Split("word").Count > 3)
However the Split() function cannot translate to a SQL equivalent, and so this can only be executed in-memory, which is excruciatingly slow by the time any number of records are involved.
The SQL to do this would be something like
WHERE Description LIKE '%word%word%word%'
And that's as far as I get - I can't work out how to get that SQL generated by LINQ to Entities. I tried the ugly hacky .Where(Function(x) x.Description.Contains("word%word%word") on the off chance, but I'm almost relieved that it doesn't work!

I have this code to set array values and store them in a variable,
Dim productName As String()
Dim productPrice As String()
Dim productCategory As String()
[CODE]...
How do you get the variable values to output like this?
<input type="text" value="Chang Beverages $19.00" id="Chang" /><br />
<input type="text" value="Ipoh Coffee Beverages $46.00" id="Ipoh Coffee" /><br />
<input type="text" value="Gula Malacca Condiments $19.45" id="Gula Malacca" /><br />

Basically, I have an array of data with about 1000-2000 data points that form a rough Poisson distribution. What I need to do is take the maximum value of the distribution (which I know), and find the leftmost and rightmost values that are, say, 70% of the maximum. (I don't really care what the value of these numbers are. I want to know what index position they are in.) I then want to find the centerpoint between these two indices, rounding if necessary, and return all three values (left, right, and center).

I am working on a very basic draw poker program. I need to analyze the hands. So far I have been able to identify a a pair, straight, a flush , and a straight flush. I'm not sure how to find three of a kind, full house, etc I have a function that uses a hash table to find out if there are duplicates in my array. I can use it identfy a sequence of cards. (i.e. if it returns a 5, that would be five cards in sequence) I'm not sure how to/if at all to use this for a pair , three of kind etc.. Maybe a differant approach would be useful. I've tried various pseudo code idea on paper and just don't see it.

I 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 have a gridview in my asp.net website that and I use vb for the code behind. Each time a row is bound an even called the Gridview_RowDatabound event is fired. So what I am doing is looping through all the cells in that row: [Code]
Problem is I get an error saying redim can only change the rightmost dimension. It would suit my needs to change both dimensions here as my final result will be to total each column in the array. what other method can i use if arrays don't suit this task.

I have a string containing many lines. Each line has many values separated by commas. Basically it's in CSV format. The number of lines is variable but the number of columns is always 7.
I can get each line into a one dimensional array using Split(Var, Chr(10)).
I'd like to make it a two dimensional array where the second dimension contains each comma separated value.
I've got
Dim VarArray1() As String = Split(VarText, Chr(10))
Dim VaryArray2(0 To VarArray1.Length - 1, 0 To 6) As String
Is there a quick way to get the contents of VarArray1 into VarArray2. I know I can do the following.
For Counter = 0 to VarArray1.Length - 1
Dim line as string = VarArray1(Counter)
Dim Values() as string = Split(line, ",")
For Counter2 = 0 to 6
VarArray2(Counter,Counter2) = Values(Counter2)
Next Counter2
Next Counter
But is there a quicker way to do it that doesn't require passing through each element of VarArray1 and then passing through each element of Values.
The eventual goal in all of this will be to find the highest value in the 3rd column (the arrays are strings at this point because not all columns are numeric). To do that once I get the values into VarArray2 I suspect I have to pass through each element VarArray2, i.e. VarArray2(Counter,2). Unless I can copy the whole third column into a SortedList?

where field1 is not null and
field2 is not null and

I need to know the IOCTL constants for the various strings (for example the value of the constant of IOCTL_ATA_PASS_THROUGH). Searching the net I found that those constants are defined in the header Ntddscsi.h but those constant are wrong. For example the constant value of IOCTL_ATA_PASS_THROUGH should be 4D02C while in the header file it is 40B
The question is: where can I find a list with ALL the right values?
I've found [URL].. where there are listed all the codes. the value in Ntddscsi.h is not the "final" value
