I want to add an array to the class `StopwatchStorage` but can't figure out how without some ambiguous warning or error popping up. The Array will contain TimeSpan type elements (essentually an array of Stopwatch.Elapsed values)

How do I declare and add a dynamically sized array to the class. I know that I will have to use the UBound function each time I want to add a new array.

.NET XML Web Service Returned Collection As An Array?

Mar 21, 2012

I am working with an XML web service using VB.NET, created using VS 2010. One of my web methods returns a collection(type that inherits from list) of custom objects. It's a simple return statement, it is my understanding that .NET handles most of the tricky protocol stuff as well as serializing/unserialzing of objects.

The issue is in my consuming application when I get the the return value of the web method that returns a custom collection I get an array of the custom objects. Is this normal behavior? It will be easy enough for me to take that array and insert it into a custom collection object but if I could I would like to skip this step.

Working on a project that tests up to 16 PC boards. The test routines are on a a backgroundworker thread. I want each PC board to perform the test routine on its own thread, so I would need up to 16 backgroundworkers.How do I go by doing this? Do I put 16 Backgroundworkers on the form? I tried to do it programmatically but I can't declare an array of backgroundworkers because withevents variables can't be typed as arrays. I guess I just need a kick in the right direction.

VS 2008 - Two Dimensional Array / List Or Collection

Jan 29, 2010

Is it possible to have a two-dimensional array/list/collection such as the following. The first dimension is to have 2 elements, 0 and 1. The second dimension I would like to be able to have a different number of elements for each of the elements in the first dimension. To explain better, I'd like X in array (0, X) to go up to say 4 and Y in array(1, Y) to only go up to say 2.

So there would be:
array(0,0)
array(0,1)
array(0,2)
array(0,3)
array(0,4)
array(1,0)
array(1,1)
array(1,2)
But no array(1,3) or array(1,4).

I'd also need to be able to use Redim Preserve to increase the size of the second dimension for each of the first dimension's elements.

VS 2008 Dgv Detail Text Box To Array Or Collection?

Jun 20, 2011

I have a parameterized query that displays the info (name, phone number, email addy) in detailed text boxes vice a normal DGV. I have coded a button to open outlook and populate the email address, but what I would like to do is have the user click another button that would add each email address into an array or collection from the desired records. Then, when they added all desired recipients to this "collection" they would hit the email button, which would open up outlook with the To: box already populated.*

I have looked into dynamic arrays , generic and special collections but am not sure what the best way forward is. When using the dynamic arrays I didn't really get anywhere, I couldn't seem to figure out how to redim with each addition of an email address.

Dim emaillist() As String
Dim listings As Double
Dim addy As String

.net - WPF Binding Individual Text Boxes To An Element In A Collection Object Or Array?

Oct 27, 2010

I need to bind a textblock.text property to a single element in an observable collection, or array element, and have the text update using the INotifyPropertyChanged or INotifyCollectionChanged, whichever is best.

Most examples describe ways to bind listboxes or other list views to entire collections, but my application needs to update several textblocks on a screen depending on notification of a change in one or more elements of an array.

textblock1.Text = MyArray(0)...
textblock2.Text = MyArray(1)...
textblock3.Text = MyArray(2)...
textblock4.Text = MyArray(3)...

Is it possible to bind a single textblock to a single array element? Is it possible to get notification of the proper type that will update one or more of the textblocks if any assigned element changes?

.net - Storing Subcollections (filtered Versions Of The Main Collection) Inside The Collection As Cache?

Collection Index Must Be In The Range 1 To The Size Of The Collection?

Dec 17, 2009

I've been working with a CMS called InsiteCreations 2008. I'm running into an error I just can't wrap my head around. I would even be willing to compensate anyone a small amount over paypal, for a solution. The error is rare in occurance, and appears when clicking about 3-4% of links to other pages within our CMS.The full code page is quite large, but there seems to be only one function associated with the error.  The error also only appears when not logged into the CMS. If logged into the CMS, clicking the link simply displays the page as normal.  I have already checked permissions on the page from the CMS admin console, and it is public.

The error message is as follows:

Server Error in '/' Application.Collection index must be in the range 1 to the size of the collection.
Description:
An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

I know you have to "write all bytes to memory" but i have two problems with that, 1. I have never touched on that itself and don't know how to write the bytes of an executable to memory, 2. I still wouldn't know how to decrypt it in memory. Right now my code is:

ElseIf entype = "rc4" Then
If File.Exists(thepath & exerandname) Then
Kill(thepath & exerandname)

it checks if the file exist then deletes it, then it opens the file and decrypts (_4reversecr.enc) the file(Cutter(1)) with the key (key)?

Add A Document Storage Module To AR Software

Jul 7, 2009

I am attempting to add a document storage module to our AR software. I will be prompting the user to attach a doc/image to thier account. I will then put a copy of this file into our folder so that we can reference it without having to rely on them keeping the file in its original place. This system is not using a database but instead its using multiple flat files.

I am looking for guidance on how to handle these files once they have attached them to our system. How should I store these attached files? I was thinking I could copy the file over to a sub directory then renaming it to a auto-generated number so that we do not have duplicates. The bad thing about this, is the contents of the folder can get rather large.

How To Create Dynamic Storage Of Data

Jan 26, 2012

I'm a junior VB programmer and looking for some advice on this subject. I'm trying to create a chunk of code that will create dynamic storage for variables for use later by dynamic custom controls.

For example:
An INI file might have an entry in it that looks something this:
....
[var1] <-- this becomes the Storage name
description=My Variable
type=System.Int32 <-- this could be any valid VB type
last_val=456 <-- Other code would save the last value
....

And I want to access the data using a standard "property set" like so after it's created:
var1_reference.value = 55
I've tried using a generic class which works ok as long as I declare the variables at design time from within the design environment. But when I try to create them from the INI file it gets messy.

Here's the simple generic class i've constructed to test this:
Public Class GenericVar(Of T)
'
' Generic Symbol Class for data storage
'
Private VarName As String
Private VarType As Type
[Code] .....

Also, as each object is created (and they could be different types) I store a reference in an array to make it easier to keep track of, but I'm having a hard time getting access to the objects and their properties, and certainly cant seem to assign an event handler to it once its in an arraylist because the design time code doesn't know what "Type" it is in the arraylist of objects.

Is it possible in VB.NET to get the directory of a file copied/moved to a removable storage device?

For example, I have msword document on my desktop and move it to my storage device. A dialog box will appear or anything that will show the directory of the document.

The idea is whenever you move a file into the specific device, it will automatically processed. I will be using this to compress a file automatically when it is moved or copied to the storage device.
