i want to see if i can get my hands on a working example of a 2d array something along the lines of continents and 5 sample countries from each continent.i would also like to know how to loop through a 2d array - i know i need a loop inside a loop but cant find any examples.i know to declare a 2d array its like: dim arrayName(,) = {{"sample","sample"}{"sample2","sample2"}}
On the design i have different text boxes that display the prisoner name, birth date, number etc.
I then set all of the the different prisoners up in an array.
I want to know how to loop though this array so that when i start the program up it will start at the beginning of the array with the first prisoners details and then when i click "Next" the next prisoners details will be displayed in all of the boxes.
I am trying to display payment details for each loan, but I am having problems displaying on the form.
Public Class MortgageDetailsCalculatorForm Private Sub CalculateButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles CalculateButton.Click
I'm writing a loop to go through the first array of a 2D loop, and I currently have it like this:
For Each Dir_path In MasterIndex(, 0) 'do some stuff here Next
But it's giving me an error, saying it expects an expression in the first field. But that's what I'm trying to do, loop through the first field. How do I fix this? What would I put in there?
EDIT: to clarify, I'm specifically looking for the 0th element in the subarray of each array, that's why that second field is constantly 0.
I define a arrary. Dim myStr(100) as string. Then the length of this array is still 0. Then is risky to cross the bound. So how to intialize this array without using a loop?
I've been looking far and wide to find the answer to my question. Its probably has a simple answer, but I am new to VB2008 and can't figure it out. I have a web form setup 30 textboxes, and am trying to find a way to quickly add them to an array through a loop.Their ID's are all - TextBox1,TextBox2 ect. I have this loop here that runs with no errors, but nothing shows up in the TextBox's on the web form.If the TextBoxes are already on the form, do I still need to declare new boxes when trying to add them to the array? [code]...
I checked the contents of the array at the end and it only held the last records within the text file, which suggest that it is overwriting the array, how can i prevent this?
I am here again begging for help with homework. I have to write this program to display three mortgage payments simultaneously using an array for three types of loans, that part of my program does work... Then I must amortize all three loans at once using a loop for comparison so the user can see: [code] I can't get the amortization to show. [code]
This program is to display the monthly payment and amortization table for three mortgage loans with the same loan amount, but three different interest rates and terms.The ArrayIndex is not looping properly.The first loan displays correctly, but the other two only display the monthly payment and not the amortization table.[code]I originally had the For...Next loop in the DisplayAmortizationTable() sub with the Do Until loop nested in it. My instructor had me move the loop to the Main() sub, but it did not help.
I am having trouble using FOR loop with array in query.What I am trying to do is for all the data pulled out of database I convert it to an array list and then string (this works fine). After that I am trying to make a FOR loop query for each of the data pulled out and this is where i am having trouble.
How do I not return duplicate random numbers with Do Until loop?
Dim numbers(5) As Integer Dim subscript As Integer Dim searchSubscript As Integer Dim randomNum As Integer Dim randomGenerator As New Random Dim isFound As Boolean
I got a value which is store in the array and i need to compare it. Which if my user = 1,2,3,4,5,6 then ignore if my user = 2,3,4,5,6 then i need to add in a ,1 which become 2,3,4,5,6,1
Here is my coding user = dr("user_access") dr.Close() Dim splitX As String() = user.Split(","c) For Each item As String In splitX [Code] .....
Is there other way to compare the array or there is another better way to check?
I'm in a pickle... either that or it's getting too late in the day. How do I loop through an array in reverse without using FOR?I have an array of string values, I need to loop through these values until I find the first instance of a value then stop. I have considered a sort on the array but each query would need me to sort it accordingly (the data in the array has many instances of the strings within strings I am looking for, e.g. there could be several 'to' but I need the first, there could be several 'from' but i need the last)When I find the instance of the string, I then need to grab specific data from that string.
Currently I'm trying to fill a 3x3 square with random x's and o's to make a tic tac toegame. Unfortunately the game doesn't seem to output all the x's and o's. Logically, from what I can see, it should be able to but it's not.
Shared Sub twodimension() Dim tic(2, 2) As String Dim min As Integer
I am working on a program that searches an array for the lowest score then displays it in the label. So far I have coded it in For Next and For Each Next loops, but now I have to do it for a Do Loop. I've gotten it to work if I have the For Next in the Do Loop, but I'm trying to not have the For Next loop in the Do Loop.[code..]
How to add the Alphabet as Char elements in a one dimensional array, using a For-loop. The length of the array depends on user input, but is generally between 5 and 15, so the how many Char of the alphabet only need to add as many as that.
This is how I have it at the moment : Public arrayLengthIs As Integer Public arrayOfColumnsLetter() As Char arrayOfColumnsLetter = New Char(numberOfColumns) {} Public Sub addCharToArray() [Code] ......
What I'm trying to do is write a program to store my sports cards collection. Basically, just a forms based program that stores various data into files. Where I am stuck at the moment is I have a piece of code that opens a form to add card brands. It has a text box, and ADD button and a CANCEL button. What I want to do is be able to type a brand into the textbox and have it store it in a array when the ADD button is clicked, then allow another entry for another brand and have it stored into the array when the ADD button is clicked and so on until the CANCEL button is clicked. Then I would like for the data in the array to be written to a file. Where I'm having the problem is I can enter a brand name into the text box but the loop keeps adding that same brand name into the array.
Imports System.IO Public Class AddCardBrand Private CallingForm As Object Private Sub btnAddBrandCancel_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnAddBrandCancel.Click Dim form As New StartScreen() [Code] .....
I am dealing with a situation which I do not understand why the loop never ends. I have attached this example. I do not know what I am doing wrong.I have 8 x 8 array of integers (TheConnectionsValue (7,7))
I am trying to port a program I wrote with old VB 1 and I have many control arrays in the program, and it was so easy to do this in older versions of VB, now I am trying to find how to do this and all the answers I have found are a major productions, to replace something that was so easy to do? I would think that microsoft would make programming easer with each new incarnation. instead they are making it harder. doing away with the DATA and READ statement, now it is much harder to fill an array with a loop, now you have to enter each item in an array ONE by ONE. they did away with the ON statement, I had several ON statements, I had to make complex Select case constructs. to replace a simple one word statement?
To make an array of controls in OldVB all you had to do is Name a Second control the Same as the First, and a dialog pops up and ask if you want to make an array, you click Yes, and that's it, what could be easier than this?
