I want to search number in array, i wrote the following code but it doesnt work
Sub Main() Dim array As Integer() = New Integer(3) {} Dim search As Integer For i As Integer = 0 To array.GetUpperBound(0) Console.Write("Enter any number for array location [{0}]: ", i + 1) array(i) = Console.ReadLine() Next Console.WriteLine() For i As Integer = 0 To array.GetUpperBound(0)

I have to search within an array and display the number of occurrences that a value within the array appears. I know that my code is incorrect but this is what I have so far. If anyone can point out what I am doing wrong that would be great.

I am trying to search the 4 columns of my array by using this click event. The column is determined by a radio button as you can see. I changed my code from last time and now it works, but only for the first column. If i try to search out a string in the second or third columns I get an error based on the line highlighted in blue HTML accutally shows and it is green. the error says Index was outside bounds of array
Like i said It works fine for all values in the first column, accually the second (Numbered 1). If i enter a value in the partsnumBox and it is found in the the 2nd 3rd and 4th columns I want the value in the first column (0) of the same row.

I need to write a program that requests a high number and a low number from the user, then the program searches the array and finds all elements within the two numbers. The program is used to search for past presidents, so if I type 43 for low number and 44 for high number, the program will display:
George Walker Bush
Barack Hussein Obama

i tried to implement DES with ECB mode but without using lib framework and i have an error in this line
Public Sub New(ByVal boxNum As Integer) table = TABLES(boxNum)End Sub
Basically I want to find the first occurrence of one array in another. I have tried using the Array.IndexOf Function, but it always returns -1. Example:
Dim array1 As Byte() = {1, 2, 3, 4, 5}
Dim array2 As Byte() = {2, 3}
MsgBox(Array.IndexOf(array1, array2))
Even though array2 does exist in array1, the message box always shows -1
"Number of indices exceeds the number of dimensions of the indexed array."
and
"Array bounds cannot appear in type specifiers."

I let the program search in the "element" parts of the html code,now the last ting I need to do is: I need to get the ID number of every part of the search results.
The line in code is giving me problems it is preventing me from searching the first part of the array but if I move it to the end or to any other spot the search wont work.

View 3 RepliesI am using following format of CustomerNumber
CurrentDate + SerialNumber
So the flow of Numbers for the month of August is as under:
010809+01 = 1080901
010809+02 = 1080902
010809+03 = 1080903
and upto
310809+01 = 31080901
The flow of program is that onClick of a button GenNextNumber a search is executed and the highest number in the table is shown in a Messagebox and on OK the nextnumber is displayed in CustomerNumberTextBox by adding 1 to the last highext number. The programme is running fine for one month. The problem I am facing at the start of next month. At the start of Month September the first number will be
010909+01 = 1090901
Now when I try to generat next number the highest number is shown as 31080901 :
Obviously because 31080901 > 1090901
But i want that the next number should be
010909+02 = 1090902
Should I change the Date format as MMddYY so that it will display the highest number with reference to highest month.

how do you filter/search a numeric number from your form feilds in vb.net. i have filtered a feild with textbox containing names(first name) but this time i would like to search/find what is containing in a numeric textfiled which is phone number textfield.A phone number is numeric and it might contain both characters and numbers. for example, one can write +44 7961400000. In textfield for fname, i have the following:
Me.EmployeesBindingSource.Filter = ("Fname Like'%" & TextBox3.Text & "%'")
--------------------------------------------------------------------------
how could i do that in phone number textfield.

I need to search through an array of X numbers (X is going to change, so for example, one instance could be that X = 20, the next could be X = 67). I need to find how many combinations of 1000 I can make. For example, each element in the array is going to be a number that is less than 1000. I want to see how many combinations I can make of the elements in the array (and what the combination is) such that the total of the combination is within 20 of 1000 (but not to exceed 1000). If getting within 20 is not possible, the range can increase to 30. If 30 is not possible, the range can increase to 40 and so on.
Every time an element in the array is used to get the combination closer to 1000, that element is to be deleted and NOT used for further combinations. The deliverable from this function would be the number of combinations along with what each combination is made of.
I went through a lot of sites about searching within an array, but I could not find any clues. I created the following array :
Private LetterArray() As String = {"A", "B", "C"}
and I don't know how to get the target letter from a "Textbox" and search "SearchButton" for it ?I have to do the following:
- Get the TargetLetter from the textbox
- Set a Boolean for Found to False (which I did)
- Use for loop For Each Letter in the Array (LetterArray)
- If the Word = the Target
Make Found True
Endif
I am trying to do a search on a index/row number taken from a dataview i.e. I enter 379437 in the input box which I know has a index/row number of 6. Now when I replace the Rows(index) with a Rows(6) I get the results that I want. When I run the code below the index comes out as 75 which displays the first row from the dataset which is a completely different set of results.

its like this if we think the original textfile like this [its meaning less] dim original as string = "myname is not thename wasthe notthe nameisnot nere!" i want to see what words are recurring, like name, the, was, not but i cant use split(), substring because they may even exist as combined words like thecat and i need to know the number of time it has recurred
View 1 RepliesI'm new here, but have been in and out for a while. Past threads have been helping me along thus far.
I'm currently developing an app which essentially needs a way for me to search in a text box or file for a specific string, and extract the line on which that string appears on. It will be unique, and the syntax is the same on each line. It has basically 2 ID numbers, and is laid out like this:
123456|123456
So, I'd need to search for the first part before the |, and then get the line so I can get the bit after the |, which is the important bit for me.
I'm new to Visual Basic.net, I've had some experience with ye old visual basic however. I'm wanting to make a quiz app that reads the contents of a text file, with about 500 multi-choice questions in it. It is in the following format QUESTION NO: 1 This is the question, what is the answer?
A. This Answer
B. Or this Answer
C. Maybe this Answer
D. Or this Answer
Answer: D
QUESTION NO: 2 and so on. I would like it to display the question number in say...a textbox, along with the question and the multi-choice. And then depending on user input, says correct or incorrect.
I'm upgrading my VB6 project to VB.NET and I found one of the problem below relating to dimensional array.Here's my VB6 coding :
Private Function ConvertMatrixToBase0(ByVal MyMat() As Double) As Double()
Dim i, j As Long
Dim ConvMat() As Double[code.]...
When i port it over to VB.NET, i encountered error message 'ReDim' cannot change the number of dimensions of an array. for the line highlighted in red. And I suspect that VB.NET need to always define the exact dimension of the array during the declaration. But for the function above, for the array of 'MyMat()', I do not know what is the exact dimension every time it runs, and that is why i need to check the dimension of the array.My question is do we have any solution in dealing unknown dimension array in VB.NET? As in VB6, we can just define Array() instead of Array (,) in VB.NET.
I am trying to write a program which performs a binary search. The user will input the name of a state in a textbox.I have a listbox which is populated with the 50 states in ABC order.The middle of the list must be determined and then determine which half of the list the state may be located. If the middle item is less than the state name the state should be in the second half of the list. If it's greater than the state name is should be in the first half of the list. The calculation for looking at the middle itemi the list is:
middle = CInt(first + last)/2)
There is a variable 'flag' which is initially set to false and then will be set to true if the state name is found. The variable first is initially set to 0 and last needs to be set to one less than the number of items in the list.Below is a very rough program fragment.
Code:
Private Sub btnSearch_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSearch.Click
Dim i As Integer
Dim flag As Boolean = False
Dim first As Double = 0

I want to be able to effectively search an array for the contents of a string.

I have a 2 column database....looks a little something like this:
Column A Column B
972CL 86.20716105
972CL 58.71034089
972CL 64.15368376[code].....
In column A there are 5 different variables (i have shown 3)....My goal code a macro to sort these by column A, calculate the average of the corresponding values in column B and ultimately end up with 5 variables that are the names of column A. e.g
972CL = average of all the 9721CL variables
972V = average of all the 972V variables
A caveat is that i will not know the names of the variables...i'm not sure if this code below is the right way:
For Row2 = 1 To 100
If Worksheets("Sheet2").Cells(Row2, Col2).Value = Worksheets("Sheet2").Cells(Row2 + 1, Col2 + 1).Value Then
testno = Worksheets("Sheet2").Cells(Row2, Col2).Value[code].....
I'm importing a text file of 42 lines, each containing 11 segments to be read. This is then split and put in an array. This is all displayed in TextBox1 for check purposes only.Next I'd like to search the array(0) of each line, and when the searched for text (search) is found, take the (1) (2) etc of that line to store in another variable which will be used for calculations later on in the program.I'll admit my head is now a Do Until = Crazy ! Loop I can't seem to get my head around the syntax and logic.How do I get a search function to check each line until the right text is found, pass the variables on that i need and exit that routine ?

I have two array I'm trying to compare at many levels. Both have the same structure with 3 "columns.The first column contains the polygon's ID, the second a area type, and the third, the percentage of each area type for a polygone.So, for many rows, it will compare, for example, ID : 1 Type : aaa % : 100..But for some elements, I have many rows for the same ID. For example, I'll have ID 2, Type aaa, 25% --- ID 2, type bbb, 25% --- ID 2, type ccc, 50%. And in the second array, I'll have ID 2, Type aaa, 25% --- ID 2, type bbb, 10% --- ID 2, type eee, 38% --- ID 2, type fff, 27%.So, my function has to compare these two array and send me an email if there are differences.(I wont show you the real code because there are 811 lines). The first "if" condition is [code]I have two different layers in a geospatial database. Both layers have the same structure. They are a "spatial join" of the land parcels (55 000), and the land use layer. The first layer is the current one, and the second layer is the next one we'll use after 2015.So I have, for each "land parcel" the percentage of each land use. So, for a "land parcel" (ID 7580-80-2532, I can have 50% of farming use (TYPE FAR-23), and 50% of residantial use (RES-112). In the first array, I'll have 2 rows with the same ID (7580-80-2532), but each one will have a different type (FAR-23, RES-112) and a different %.
In the second layer, the same the municipal zoning (land use) has changed. So the same "land parcel" will now be 40% of residential use (RES-112), 20% of commercial (COM-54) and 40% of a new farming use (FAR-33).So, I wanna know if there are some differences. Some land parcels will be exactly the same. Some parcels will keep the same land use, but not the same percentage of each. But for some land parcel, there will be more or less land use types with different percentage of each.I want this script to compare these two layers and send me an email when there are differences between these two layers for the same land parcel ID.The script is already working, but it takes too much time. The probleme is, I think, the script go through all array2 for each row in array 1. What I want is when there are more than 1 rows with the same ID in array1, take only this ID in both arrays.Maybe if I order them by IDs, I could write a condition. kind of "when you find what you're looking for, stop searching when you'll find a different value?
