i want to declare an array with a name that is the value of a variable. I need to do this because i want to create arrays from a text file that i'm reading.Basically, if someone could make this work then i should be able to change it to fit my use.
Dim var1 As String = howdy
Dim var1() as Integer
In this case i'd like to be declaring an array with the name 'howdy' that stores integers. In reality i'm looping a bunch of read names and would like to create an array for each name i read- but i'm quite capable of sorting the rest.
I need to store elements in a multidimensional array. Specifically, I need to save "tiles" to a grid (e.g.Grass at x:2 y:5, Dirt at x:3 y:5, etc.). Using a multidimensional feels very hacked up and is very glitchy (having to resize my arrays and having to create new ones were they are non-existant). Is there some kind of element made for this? Something I can say obj.getPos(2,5) and get my Grass Element and use obj.setPos(DirtObj, 3, 5) to set it to my Dirt Element?
I'm just wondering if there is something easier to use than multidimensional arrays in vb.net, that is all.
I have a Comma Separated value file in .txt format... simply put, its a bunch of data delimited by commas and text qualifier is separated with ""For example:
"So and so","1234","Blah Blah", "Foo","Bar","","","","" "foofoo","barbar","etc.."
Where ever there is a carriage return it signifies a new row and every comma separates a new column from another.My next step is to go into VB.net and create an array using these values and having the commas serve as the delimeter and somehow making the array into a table where the text files' format matches the array After that array has been created, I need to select only certain parts of that array and store the value into a variable for later use.... how to make the array and selecting the certain info out of it..

I developing a roster application (asp.net with VB + sql server) to let user input shift duty record, proposed screen as follows:for the database design, each staff will have one record per day.[code]I want to create a multi dimensional array to bind the gridview.Is that correct that I create a arraylist (for 7 days) and then a subarray for each day? How can I create a 7 dimensional array & sub array under this 7-D array in asp.net + VB ?
I have created an array of 6 numbers which are randomly generated, I can create a graph using six randomly generated numbers, however what I want is to use the random values that are placed in the array to create my graph, I have enclosed the code that I have:
Private Sub btnGraph_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnGraph.Click txtAns.Text = ""
is there any way of creating a file in visual basic using a variable as the file name? I have tried using the following but keep getting an error "The given path's format is not supported." ??? I am trying to create a log file of machine use every shift (8 hours) and just want to use the same name for the file with the date and time appended to the end of the file name. the section of code giving me the error is below.

Imports System.IO Public Class Main Dim image_1 As Integer = Openimg1.FileName 'The line below is the one causing my problem Dim image_2 As Integer = My.Computer.FileSystem.RenameFile(Openimg1.FileName, "_hid" + System.IO.Path.GetExtension(Openimg1.FileName)) [Code] .....
So basically, how can I create a variable from something that has yet to be created?
how do I DIM a variable's name using previously declared string varialbes? I have been using PERL for processing data stored in text files but I now have a business need to use VB2008. I would like to do something like this:
dim name1 as string = "ABCD" dim name2 as string = "123"
'here is the part that I don't know how to do - create a 3rd variable name concatenated from name1 and name2:
dim string.concat({name1,name2}), or maybe use a counter in a line like 'dim namex as string' with x being a counter value.
Essentially I want to dim variables using text strings extracted from a file. In PERL I have declared literals and arrays, such as 'my @$name1', which creates an array named with the contents of $name1. In VB2008 I am not sure how to make this work with the DIM statement.
Is it possible to create a variable that is global for each session in ASP.NET? Usually I do this with Session:
Session("my_variable") = 10 But this necessitates casting it every time I want to use it like so: Dim my_variable as String = CInt(Session("my_variable"))
I'm trying to elaberate on some basic examples of .Net programming in using VB. The basic example of creating a new instance of Form1 is: Dim x as New Form1 x.Show I've added some OptionButtons to set the StartPosition of the Next Instance of Form1 as well as some Labels that display the Top, Left, Width and Height properties when the new instance of Form1 is Shown.
This is the code I'm using. Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim x As New Form1 If Me.RadioButton1.Checked = True Then x.Top = 0 x.Left = 0 [Code] ......
Ok I'm creating a sql query with a string variable and executing it in vb. The string would look something like: Insert Into Table (vara,varb,varc) Values ('vara','varb','varc') This works fine.
Im trying to create a diary system that on click event of the built in calander in vb.net opens the current diary entry for that day. i am using the my.settings variables to store the entrys the problems i am having is how to create a my.settings variable automaticly if one dosnt exist for that date (will be using the date of the clicked day as the name e.g. 10/5/2011)
So basicly i want the user to be able to click through the dates on the calander and the entry be displayed in a text box next to it, blank if nothing is there and the user can edit/save them after just need the code to auto create and i guess how to search the my.settings im quite new to using this storage, i normally use text files. the pic shows the program so far, it has one diary entry but it has no relation to the date. the label is linked to the calander also , displaying the selected date.

if i generate a label dynamically i can change the text as followed, variable is a string: Form.Controls(variable).text = "test" I now have a sub that will create some and will get some information out of arrays. I have a lot of them. I only want the function for tat specific array. I do not want a case or if. Thats why i was wondering if i can use a variable in the array variable. [Code] But instead of TestArray being hard-coded i want it to be replaced with Shelf. So whatever gets send into the sub will change the array that i'm using. Is that possible some how or is the way totally wrong?
I'm trying to create a small program where someone would select one of five items from a list box (Hot, Medium, Mild, Sweet, Zesty). When they select this, they then enter in a qtyTextBox the quantity they want, ie.e, 1, 2, 3, 5,... Then they the Calculate Button, which then the total would go into the preDiscountLabel box, where it would calculate the amount they want * the sale price. Here is the Price Listing:
How can I create an array of a class that I have declared? I have this class named partswith properties of frame, engine and date, and i want to know how could I store them in an array .
I need to be able to refer to a set of controls on a Windows form using an array, but I'm having a few difficulties.
The Windows form (WForm.vb) contains two textboxes (TextBox1 and TextBox2).
In Module1.vb I have created an array reference to the textboxes thus:
Public wf As New WForm Public ReadOnly TB() As Control = {wf.TextBox1, wf.TextBox2}
Then, in WForm.vb I have tried to refer to the textboxes via the array:
eg.
TB(0).Text = "Change text to this"
I know that the array is referring to the textboxes, because when I hover the cursor over the line 'TB(0).Text = "Change text to this" ' in debug mode, I get the following:
(0)|{Text = "Change text to this"} (1)|{Text = ""}
but for some reason, the text in TextBox1 on the form isn't actually being changed! (There is obviously no problem with change the textbox's text at this point in the code, because I've tried substituting the array reference 'TB(0)' with a direct reference to the textbox 'TextBox1', and the problem disappears.
I need to create an Array of Labels. I am using A With Code block to set the properties of the Labels as well as the Data Binding. I want to set the LabelIndex inside this block as well. How do I go aboute this?
I'm writing reports in Report Designer (VS 2008), and I've reached a point where I have to circumvent the restrictions on using aggregates in groups. I believe this can be done by utilising custom code, which is written in Visual Basic as far as I know (not sure what version though).
I have a dynamic number of "Pools", which each contain "Models". Each Model row needs to set the Pool Multiplier to the maximum of the current multiplier and proposed multiplier. The Pool row (parent group row) then needs to get the Pool Multiplier.[code]...
I'm having a problem at the moment developing my application. What i need to do is find out how many modems they are connected to my system and send data to each one in turn. I have the programme working for one modem at the moment.
So I can send data to a modem that i specify, for example a modem on COM port 1. I have functions already that will give me a list of COM ports that I need to open.My problem is that i want to dynamically create a new modem object along side existing modems and store them in a collection.
I have a group of boxes witch will all hold data input by the user. I am using an arraylist to store these, or atleast I am hoping to. So, the problem I have is getting the data to actually save to the arraylist. It keeps giving the error saying that type string cannot be converted to array list.
[URL]..And put into a dynamic array where each month represents a record in the array with 3 given with C/P, Strike and Settle
The criterion is for every month grab all C/P that have matching strikes thus returning the following for every month. See data below and what I would like to return below. Want to use excel VBA to return the values from array into a sheet in excel. See data below
