View 2 RepliesDeclaring & Initializing String Array?
Mar 10, 2011I'm trying to return an array of strings from a function, and got surprised by an error.
I would have expected this to work, but it produces an error:
Public Function TestError() As String()
Return {"foo", "bar"}
End Function

I guess I'm unclear on the meaning of the {}'s - is there a way to implicitly return a string array without explicitly creating & initializing it?
Declaring A Variable Length Array?
Apr 26, 2010I am new to VB.NET but used to write a lot of code in VB 6.
How do i declare a variable length array in VB.NET?

Declaring Jagged Or Rectangular Array
Sep 21, 2010I'm working on a reporting section of code for an inventory app I'm making for my office.I call a text file, read every line into an array then populate information pages with what has been pulled from the text file.For reporting, I want to read every text file in the directory, reading each one into a multidimensional array.Thus I can call and report on each item, i.e.ItemArray(i,2) would be all systems with Windows 2008 EE..I have code that lists all files in the desired directory and counts each file, so I eventually get counts of how deep I need the first level of the jagged array to be. but not until after code execution. Basically how can I write each array of data to the jagged array.[code]But I get a null reference exception. "Use the new keyword to create an object instance".

Creating And Editing An Array Of Labels?
Nov 18, 2008i am attempting to create and then update data in Labels using VB2005.I create the label when the form is loaded using this for loop
For j As Integer = 1 To count
Dim name As String
Dim m As String
ReDim L(count)

This creates the labels and text boxes in the form. Later in the program I would like to change the text within both the T1310() and T1550() text boxes and I am attempting to do so with the following code.

status = OP930_SelectModule(j - 1)

Array Of Labels - Converting String Into Object
Apr 2, 2012So, I'm creating an array of labels. I have labels set up as:
labal1
label2
label3
etc...
I've declared the array as such:
Dim labelArray(5) As Label
Now, instead of assigning the labels one by one to the array (labelArray(0) = label1, labelArray(1) = label2, etc...), I was hoping to use a loop (there will be more than 5 labels). I have something like this, which obviously doesn't quite work:
For i = 0 To labelArray(i) = "label" & i Next
Is there a function that I can use to convert the labelName string to an object, or have vb.net see that as an object instead of a string?

Mar 13, 2010I need my app. to Create an Control Array at runtime that will consist of up to 50 Data Bound Labels. The app. will first be checking the 1st database field (Ing1) to see if there is data, if so then only create the 1st Data Bound Label (lblIng1) and then check the next field and so on.
The problem is that VB 2008 dos not seem to support Control Arrays. There must be another way to work around this.
VS 2005 : Put Existing Labels Into An Array (to Loop Through And Change .text Property)?
Jun 23, 2011I am writing an app to be a single button failover of a set of mirrored SQL servers. The app has to handle several other functions (enable/disable and start/stop of services, writing to local registry, copying files from server A to server B, initiating stored procedures, etc.)I have a collection of labels that indicate the status of 4 services on 2 servers, I wrote a function to check the services when passed the machine name, and the service name. Originally I just called the function 8 times (4 services, 2 machines) and populated the labels 'manually'. I have all of this within a timer so that the service status is refreshed every couple seconds. Id like to clean up the code to a single for/next loop that operates on 2 arrays (an array of service names, and an array of labels) such as:
'**Fetch_Status is the function that gets service status, it accepts 2 strings, machine name
'**and service name and returns status "running", "Stopped", as my_status
Dim Services() As String = {"Service1", "Service2", "Service3", etc.}
[code]....
The only reason I want the control array is to be able to use the .Text and .BackColor properties of the labels in the loop. If I make an array of strings with the label names it doesnt seem to pick that up.

View 1 RepliesInstruct VB To Save These Values In The Text Property Of The Labels So That The Next Time The Program Is Loaded The Labels?
Oct 21, 2008I created a program that has serval labels on a form and a listview object. It has a button that when clicked reads a textfile and loads up values in the listview object. I then can click and drag text from the listview box to any label on the form and then the program removes the value from the listview box. Now, my question is how can I instruct VB to save these values in the text property of the labels so that the next time the program is loaded the labels will contain the values loaded during the last run time session?

Project - Add And Resize The Labels - Create Scrolling Labels ?
Feb 5, 2009With VB, but I've got the few basics down, file naming, adding objects, naming objetcs, etc. But the reason I'm on here is because I cannot complete even the first step. Our form is 640 X 480, and we need to have two labels, both have vertical scrolls. I know how to add and resize the labels to meet my needs, but I do not know how to create scrolling labels. Or are they text boxes? On our bubble chart (Do you know what that means?) it says lblInformation. We are going to have clickable radio buttons which will update the lblInformation with info about each of the radio buttons.

Is there a way to have a label on each row in a listview that shows the row #?
