I put a button control name 'BTT1' on form and all property are set through property window..and In form_load events i want to create 10 more button which property are same as 'BTT1' so how i can assign all property of 'BTT1' through one or two line of code ...like
--------------
for i=1 to 10
dim b as new BTT1
b.name = "b" & i
[code]....
All Handles of new created button also assign to handle of BTT1 (more clear: all subroutine handle mousemove, click, etc of BTT1 also works for new created Button (b1, b2 ...b10))..

from the documentation we have this: Multicast Delegate: Represents a multicast delegate; that is, a delegate that can have more than one element in its invocation list.
so am i right to say that Multicast delegate is no different from a normal delegate other than the fact that it has arguments. so System.Action is a 'normal' delegate whereas System.Action(T)(Byval obj as T) is a multicast delegate?
I have a program which use an API. One of the functions of this API has threading.Once I start this function. It will continue reading data and once the data is found, it will pass me the data to a function let's say functionnd I call a delegate functionB from this functionA.And at some point this functionB throw me an error of "Collection was modified; enumeration operation might not execute.".Does anyone know what this mean?I google it and found that this error was caused by "For Each or For" loop.But in my program I don't have any for loop.

View 1 RepliesI am trying to write a VB.NET alternative to a C# anonymous function.I wish to call Threading.SynchronizationContext.Current.Send which expects a delegate of type Threading.SendOrPostCallback to be passed to it. The background is here, but because I wish to both pass in a string to MessageBox.Show and also capture the DialogResult I need to define another delegate within. I am struggling with the VB.NET syntax, both from the traditional delegate style, and lambda functions.My go at the traditional syntax is below, but I have gut feeling it should be much simpler than this:
Private Sub CollectMesssageBoxResultFromUserAsDelegate(ByVal messageToShow As String, ByRef wasCanceled As Boolean)

View 1 RepliesI am using TextFieldParser to Read a Tab Delimited Text DataFile. The problem I have is that some times the data file (3rd party provided) contains an extra Tab which therefore creates an extra column. I need to remove this unnecessary column. Some columns will have rows that are empty so I cant just delete the column if it has a blank row, So I think I need to loop through each column and if if every row is blacnk then delete that column.
Here is the code that reads the file, I was going to remove the column from the table called table before I populate the table called dtAll , which is what my program uses
Dim safeFileName As String = IO.Path.GetFileName(Me.OpenFileDialog1.FileName)
Using myReader As New Microsoft.VisualBasic.FileIO.TextFieldParser(safeFileName)
myReader.SetDelimiters(vbTab)
