This is a school project, supposed to be a beggining VB.Net class. I'm having difficulty with one section, sorting the array is OK but I need to only return a 3 of it. I had it working when I was selecting single files but when I went to selecting multiple files at once the formula stopped working for me. I'm retuning the array just fine but the select a 3rd seems to just pass by without being acted upon. I've been working on this a long time and don't know where to look for an answer. Here is what I have for the sort method;
Private Sub sort()
Dim Count As Integer
Dim count2 As Integer
Expected Results: A scalar result of the comparison between Array1 and Array2 such that when Array1>Array2 it is true. See expected array above. Actual Results: When Result(x) is true, all elements become Array1(x) and Array2(x) .What is wrong with the function?
I want to go to a class.vb file that has a function from an aspx page and I want to return mutiple arrays. Is that possible? If so, how would I call it from the aspx page and how would I return it?
Can this be rewritten any better using LINQ? I'm a C#er trying to think in VB.NET for this current project. It's in an ASP.NET Web Forms .vb codebehind:
Public ReadOnly Property AllowedCategoryIds As Integer() Get Dim ids = New List(Of Integer)
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?
In this application I need to allow users to enter a month as integer (1-12) then use integer tryparse to validate that input, that seems to be the easy part. I need two create two functions, one that returns the name of the month and the other returns the number of days in that month. The arrays are supposed to be defined and initialized within the function so that the main program can take the user input and call the two functions, then return the appropriate values as output to labels. I am not sure how to declare the arrays in their appropriate functions and then how to call those functions to retrieve the right value from the function.
I would like to update string arrays in batchlets say I have 3 string arraysI want to for example redim them and then up load them with data.I have tried for each on array of arrayI have tried list.at the end none of them are updated.
Dim Str1(10) As String Dim Str2(10) As String Dim Str3(10) As String
Dim RoomName() As String = {(RoomA), (RoomB), (RoomC), (RoomD), (RoomE)} Dim RoomType() As Integer = {1, 2, 2, 2, 1}
I want to get a value from the "RoomName" array based on a criteria of "RoomType" array. For example, I want to get a "RoomName" with "RoomType = 2", so the algorithm should randomize the index of the array that the "RoomType" is "2", and get a single value range from index "1-3" only.
I have an array for all 26 chars of the alphabet as a boolean. What I want to end up doing is have the program take the user's guess char and set the corresponding number in the array to true. I'm new to arrays and I have no clue how to begin doing this. this is how I am declaring my array. I am declaring the array as a char for now because I don't know how to go about using a boolean array for my game, but it seems like it would be the best way to do it. [Code]
now I want to create a 3rd array which should at least contains one numeric number and rest of alphabets, this code will generate unique usernames so it should not repeat the pattern of selection which is present in main array[code]...
A project requires to allocate a varying number of byte arrays (buffers).
It would be ideal if the following definition would be possible:
Dim ArrayOfBuffers() as buffer(10000) as Byte
The byte arrays must be ordered sequentially because they have to be written to a file by efficient procedures destinationFile.Write(ArrayOfBuffer(3),1000,1000)
The number of buffers will change during program execution sometimes. Therefore it would be nice to be able to do a ReDim on the data structure when needed.
This does not compile. Dim Tom As New List(Of String) = {"Tom", "Tom2"} This does Dim Tom As String() = {"Tom", "Tom2"} IMO this features should be allowed for all collection types and not only arrays.
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?
Is there any way to create a multidinensional array that contains arrays of different lengths (similar to nesting arrays of different lengths in python).
Because if I were to declare a variable Dim accounts(2,2) As Integer all 1D arrays at each dimension have the same length. Is there any way to create an array so that this is not the case?
e.g The above code would create an array like this: [[0,0],[0,0]] but would it be possible to create this: [[0,0],[0,0,0]]
How to get values for array elements in VB.nET from the user.also i wanted to display these values in the combo box.[this is easy i could manage this].
I have several parameters consisting of separate System.Byte() arrays. What I need is the syntax for a function declaration where the parameter is an array of arrays - I do not want to delve into System.Collections, and it's my preference not to CType each array into an Object and then back into a Byte().
Problem I'm having here is that:
Public Function MyFunc(arrayparam() As System.Byte) As System.Byte()
accepts a single-dimensional Array of individual Bytes.
Then Public Function MyFunc(arrayparam() As System.Byte()) As System.Byte()
I have written a class for my one dimensional array The idea is to collect user information, put the info into an array and accumulate the value of each item of the array so there is a running total. The problem is that the code is not totalling the array when my btnSum is clicked or maybe at all. I am getting no errors, but I am also getting no total.
Create two arrays, ask the user to populate them and display both arrays Swap the contents of the arrays using loops and then display the content.
What is the best method to have the end user populate an array? I am doing this as a windows form. Have multiple text boxes that they have to fill out? Set the elements of the array to the text box values? And how to swap the contents at run time is something I am not sure of. Isn't there a Array Swap function or something? Here is what I have so far:
Note: the bottom section was a test..and it isn't working as expected.
i have a array set up, and i need the array to be global, but i can only get vb to accept it in a button, in addition, after the loop is completed, i am trying to pull a value from the array and display it but am getting an error.the code is as follows:
Public Class Form1 Friend staten As String Friend statea As String[code].....
I have a database table of company information.It's about 50 records and contains things like company id, company name, address, phone number, shipping rate1, shipping rate2,etc.I want to load that table into a structure that I can quickly search within my code.I want to search by id to find the company, and then use the company's data to update some records.My lazy way has always been to add a listbox for each piece of data, then do an indexof on the id, then access the same index on the other listboxes.[code]
Once i allocate arrays is the memory allocated for them immediatlyy or once i add data to the array? like say i create an integer with 400 million arrays (lol) would visual basic allocate memory immediately for each of the 400 million arrays or once there is data allocated to one of the 400 million arrays, say when i put the number 4 in the 100th array.
Before adding rows to a table I am evaluating the SSN number. These will later be flagged for correction so I am setting a datatable column to true or false if it passed muster or not.
I wrote a function to check the number and make the determination plus pad it with zeros and hyphens where they should be. My problem is I want to return the results in an array. I am getting system.string[] as the return value.[code]...
