I tried this
vb
Dim matches As String() = Regex.Matches(tmpFieldContent, strEmail).Cast(Of Match)().ToArray()
But it didn't work, as vb says
'Cast' is not a member of System.Text.RegularExpressions.MatchCollection'.
I have a collection which I wish to retrieve an array from in .NET 2.0. In other words, I want to convert a collection into an array. So far I have the following:
Public Class Set(Of T)
Implements IEnumerable(Of T)
Implements ICollection(Of T[code]....
I know how to remove duplicates in an array (have a simple function for that) but now I was trying to do the same in a matches collection and I can't get anything to work somehow.
In this case the matches collection has a few duplicates that I want to remove.
Dim matches As MatchCollection
matches = Regex.Matches(sExtractedText, "word=""[dw]{8,30}""")
For Each match As Match In matches

I have an array of items where i have separated the first two characters, which in my case are ID tags. I have populated my CLBox and the output is like this
AA
Aa
BB
[Code]...
What would the process be to do this, would i need to create a reference list or stringbuilder for all the tags(there is about 3000 tags) or would it be possible to loop through and count the matches. I declared the Tags thinking that i could do something from there.
'this calls the connection sub
connection()
SQL = "SELECT * FROM Customers WHERE Surname Like '" & Textbox1.Text & "%'"
'this calls the DatagridFill sub
Datagridfill()
This is my current code, it searches for anything entered into the textbox against the row "surname", but I also have a first name row and a Order ID row. Instead of searching against one row, i want to to search all the rows, and fill the datagrid with anything it matches it with.
I need to convert a VB Collection to a modern one, like Dictionary or Hashtable. For my approach, I need the Collection's KEYS. Googling tells me that it's impossible. Re-writing the entire application using new collections is not an option as the application is really old and large (converted from VB6 to VB.Net).Using the old Collection also is not good - as there are new components in development.Converting a - for example - Hashtable to Collection works:
using VBCollection = Microsoft.VisualBasic.Collection;
public static VBCollection ToVBCollection(this Hashtable table)

I am working on my program as I'm adding the listview subitems string in the label.Do you know how to remove the listview subitem in the label when the matches are found?
Private Sub listView1_MouseClick(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs)
Dim item As ListViewItem = listView1.HitTest(e.Location).Item
Dim a() As String = Nothing
[code]....
When I use the code on above, it doesn't remove the listview items in the label when I click on the checkbox on each row. Do you know how to remove the string in the label when I click on the checkboxes in the listview while the strings in the label is matched with the listview subitems?
I have an one dimension string array ar1
ar1(0) ="One;is;a;dog;"
ar2(1)="Two;is;a;cat;"
...
I want to convert ar1 into ar2 which is a two dimension array
ar2(0)(0)="One";ar2(0)(1)="is";ar2(0)(2)="a";ar2(0)(3)="dog"
etc
I have the below code and it works fine, it's this way because I need to manually calculate some data before adding it to the Listview control.

Dim mList As List(Of ListViewItem) = mDataBase.GetRecords(LvwChecks, "CheckGroups", <Query>, GetType(CheckItem))
If mList.Count > 0 Then

I am trying to convert a collection to a string. When I am done, it should look like String() = {"File1.Tif", "File2.Tif", "File3.tif", "MergeTiffImages.Tif}. Here is what I have so far.
Dim FileArray(0) As String
Dim Count1 As Integer
Count1 = 0
For Each k In S
ReDim Preserve FileArray(Count1)
FileArray(Count1) = """" & k & """"
Count1 = Count1 + 1
Next
FileArray(Count1) = """MergedTiffFile.Tif"""
I am getting the error "Index was outside the bounds of the array." because FileArray is a string and not an array.

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.

View 8 RepliesThe following image or RTF file illustrates how I'm trying to transform an input Byte array into an output array of Booleans. This is basically what I have listed below. figure out how to get from one array to the next while shifting values of bytes within 8 byte groupings to shift low order to high order or vica versa. What I mean by that is best seen by looking at the illustration of actual input an required output. The reason for this is that the hardware devices have registers and the display which can be seen in the links above needs to convey the disabled sensor cable cell locations.

View 3 RepliesIs 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.
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
