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 am getting the error:"Range variable 'sender' hides a variable in an enclosing block or a range variable previously defined in the query expression."for this
Imports System.Data.SqlClient Imports System.Linq Public Class Form1
[code]....
I can select any other item from the table without the error. "sender" has the same properties as "receiver" in the SQL table.
Public Class Form1 Dim x, c, number(0 To 19) As Integer Dim s As Integer

The variables in the brackets [example] do not actually have brackets in them in the original code. These are where the issues are. For both variables, it says, "The type for variable [variable] will not be inferred because it is bound to a field in an enclosing scope. Either change the name of [variable], or use the fully qualified name (for example, 'Me.[variable]' or 'MyBase.[variable]')." Now, I'm not entirely sure if this is a stupid question or not, as I'm used to VB '98 because that's what we use in my programming class at High School. let me know why this won't work.
-Note: The intention of this program is to continually loop the generation of numbers for this list until I tell it to stop. Button1 ends the program, Button2 generates the list one time only, Button3 is supposed to loop the generation of the list, and Button4 is supposed to end the loop, but not the program.
Say that i have the following code that parse about 20k records from the DB.
Code #1
vb.net While reader.Read() list.Add(If(Integer.TryParse(reader(0).ToString, 0), Integer.Parse(reader(0).ToString), 0)) End While
And then another code which does the very same thing but it seems to be a little cleaner.
Code #2
vb.net While reader.Read() Dim storeowner As Integer = 0 Integer.TryParse(reader(0).ToString, storeowner) list.Add(storeowner) End While
This is what i am confused about; does the compiler creates a new variable automatically when i use the if statement without strictly declared variable? What approach is better in sense of performance?
I am looking for a good resource on variable naming conventions to illustrate variable type and where variables are declared. So I will have public variables, Private variables, private or local variables. I also may want to declare variables with the same name in different class code (i.e. in the code behind different forms). I am assuming good coding would dicatate a prefix for declaration location.
i have this error in the line of with xl.active......Object variable or With block variable not set.
Dim xl As Object xl = CreateObject("Excel.Application") With xl.ActiveSheet.QueryTables.Add(Connection:= _ "TEXT;C:Documents and SettingsUserDesktop429MEDICA2.TXT", _ Destination:=xl.Range("$A$1"))
Now I have the need to get a current value from a bindingsource in a property of a user control.In a previous thread I had tracked down the "Object variable or With block variable not set" to the return in the Get block of a property. At the time I was only using the Set so I just commented out the offending code until I needed it.
[Code]...
The error does not occur during a system compile, only upon saving the container object of the user control. As I said the Set works correctly, only the Get causes the error.I would like to know what I am missing/misunderstanding and am open to other suggestions of handling retrieving the current value of a bindingsource in a user control.
I am using vb2008.net express,I test vs2005term it work, can any tell me what is the input variable and output variable of this terminal?how to catch the input and output variable to a textbox1 for sending and a textbox2 for receiving when I press send button? is that possible?
I have the following code that I am using to parse out a test file. I am getting variable conversion error in Sub Main() when I assign file = Read(). The return value of Read() is a TextFieldParser type. How do I assign the proper variable type to "file" so I can write the output to a text file?
Function Read() Using MyReader As New FileIO.TextFieldParser("C:UsersColinDesktopParse_Me.txt") Dim currentRow As String
I have the following code but I get blue squiggly line in cnn and when i point my mouse pointer on it i see this message "Variable 'cnn' hides a variable in an enclosing block"

I have the following code passing a dataView variable to a function and I am getting the following warning:"Variable 'cl' is passed by reference before it has been assigned a value. A null reference exception could result at runtime."

I'm having trouble tracking down what is wrong and causing the above error. This only occurs when saving the design view in VS 2012. The code builds and runs fine.Full error text:Code generation for property 'CompanyValue' failed. Error was: 'Property accessor 'CompanyValue' on object 'ContactViewUC1' threw the following exception: 'Object variable or With block variable not set."

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]...
how to add a counter variable to this array? My code always stops when it gets to an empty array. I can't figure out how to make a counter variable to make it stop.
Private Sub btnTwo_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnTwo.Click For Each i In PlayerArray
I have a variable (double) which has a constantly (infinitely) changing value. I would like to store all the values of this ONE variable into an array. My variable and array are:
Dim x as Double Private y as Double() = New Double (499) {} I tried doing this:
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.
ok, I got a lot of conceptual code for major chunks of the game's engine...like an inventory array of variables... he says that we will be using a lot of variable arrays, and I am trying to get a variable array dimmed in an inventory module, but when I try to declare what each index of the array should be, it says "declaration expected" and simply trying to reference the array from within another form, it does not register as existing...
the code is as follows, for he has not a clue how to program in vb.net
dim character_inventory(19) as array
and when trying to tell vb.net to set an individual index to nothing, it throws a "declaration expected" error...
character_inventory(0) = nothing is when it throws that error...
Is it possible to use a string as an array? I mean: I have several arrays Dim a10() As Integer = {530} Dim a15() As Integer = {370, 231} Dim a20() As Integer = {305, 176, 126}
'I declare a variable as a string and I assign the name of an array to it Dim tablaalfa As String = "a10" 'I retrieve data from the array using the name of the variable instead: lbl1.Text = tablaalfa(2)
