Code:
Dim Users As New ArrayList

The reason I am looking for a query way to do this is because I will not know what the second dimension value will be.

VS 2008 Storing Information To An Array Or ArrayList And Displaying Each Item In Label?
Apr 22, 2010I have a list of names in a database and what i want is to get all of these names and display them in a label or a text box to the user on the website. I have tried to do this using a for loop but it is always overwriting the label each time. I have a list of 10 different names in the database and what it is doing is putting the first name in the label and then overwriting this with the second name and so on until it reaches the last name. I think i need to store each of the names from the database into an array or an arrayList and then make the label display all of the contents from the array or arrayList. The for loop i have used for this is:
Dim g As SQLadmin = New SQLadmin()
g.DB("SELECT nameOfPerson FROM Persons")
For i As Integer = 0 To g.array.GetLength(0) - 1
[code]....
i can select the names from the database and store them in an array then make the label display each of the names.

View 5 RepliesRemove A Context Menu Item?
May 21, 2009how to delete a item from the context menu.. i can add a item with this code:
Private Sub Button7_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button7.Click
ContextMenuStrip4.Items.Add("delete file")
End Sub
no problem there. and to delete this item, i figured since it is the 4th item in the contextmenu (and i can't type the "delete file" either w/o error) it would delete it by index, with this code:
Private Sub Button8_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button8.Click
ContextMenuStrip4.Items.Remove(3)
End Sub
the (3) is giving me a error "value of type 'interger' cannot be converted to 'system.windows.forms.toolstripmenu'".. i think that means that the context menu does not support indexing.
