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:
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 a two different tables, Table 1 and table 2.
Table 1 ----------- Resource Start Date End date
[Code]....
Here I have to match the total hours of each table according to the resource, then have to find the mismatched data and find difference with that values of mismatched data.
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 need to sort an array. I need the most repeated strings at the start and the least repeated at the end. Any easy way to do this? My brain is currently fried
I am creating a maths programs that draws graphs for the user. so far i have placed 22 values into an array and now i need to import them to excel, draw the graph and import the graph back into the program to display them.[code]...
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.
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.
Per this UserControl that can be added to a blank form, I would like to use the HorizUnits array below to map custom grid x coordinate from a mouse x position.For a given input value 13, what syntax would I use to obtain a value of 2 where 13 lies between Value 10 and 16 for which 2 (Name) would be the custom grid's displayed coordinate position?
I have an array of people stored in a custom structure array... how can i copy this array to a temp array so that the temp array has all the same values as the original custom array?
I am writing a pizza order program for class and have gotten everything put together, even got my array setup and displaying but when i go to calculate it will not calculate the values coming from the array in any of the calculations.

As per this illustration, I'm trying to increase the size of an existing array from 111 to 114 to be consistent with existing code. I need topreserve the existing values and add 3 new items to the end of the existing array of booleans,
Row3 ;W910 RF350022 ;Increase backlight by 100% ;(c) spring ;(p) spaceman +1000000 F5 000000 5555 44 555555 904938291 8676859 00
Row4 (Duplicate of Row3) ;W910 RF350022 ;Increase backlight by 100% ;(c) spring ;(p) spaceman +1000000 F5 000000 5555 44 555555 904938291 8676859 00
if label1 = RF350022 label2 = Increase label3 = spring label4 = 100%
only if it contains all of these words it should return the first instance (row3) then end or null the rest (row4).how can i get row 3 to show in message box now it has been found?
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?
how to find max values using MySQL as the database? examples in the database ID (primary key and AutoNumber) data that will come 12. so, in the form at the moment want to add data, automatic number 12 also
I'm building a program to read a text file and display and find the min and max values within the textfile and display them in text boxes (txtMac, TxtMin) for the user. The program also needs to count the number of items in the text file and put the number in a textbox called count.
So far i've made the code to find the max value (below) but have no idea how to get min value and count.
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:
Dim myarray(5) as int
does, at this point in time, myarray(3) for example have a defined value? If so, what is it?
I am trying to extract querystring values from a htmldocument. It contains a number of anchor links with a querystring parameter called id. I would like to get all the ids in a commaseperated string. How can I fix this? So I would like to get: Result = {1,2,3,4,5}
I need to find rows in resultsets that have every column without null.these resultsets got variable number of columns.currently, the only way that I can think of is creating a view on each resultset and filter this way:
select field1, field2, field3, field4, ... from "huge query" where field1 is not null and field2 is not null and
[code]....
and then in a storeproc/function or .net code(c# / vb.net) loop through all rows / columns and flag or remove every row that got any null?
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
