View 2 RepliesGenerics - How To Limit Size Of List
Mar 24, 2009I am trying to limit the size of my generic list so that after it contains a certain amount of values it wont add any more. I am trying to do this using the Capacity property of the List object but this does not seem to work.
Dim slotDates As New List(Of Date)
slotDates.Capacity = 7
How would people advice limiting the size of a list? I am trying to avoid doing a statement to check the size after an object is added.
Limit To The Maximum Amount A List(Of T) Can Hold?
Aug 3, 2009Is there a limit to the maximum amount a List(Of T) can hold? I need to know because I have a program that could potentially wind up in a really large loop that would add over 200 or so items to a list at one time.
MSDN search didn't really tell me much, but I'm in a rush at the moment, and was just wondering.

View 1 RepliesForms :: Limit The Width Of A Tooltip?
Dec 30, 2009I am using tooltips to show information that overflows a label. The problem is that when the information is really long it spans the entire width of the screen and is difficult to read, Is there any way to limit the size of the tooltip?I was thinking one way may be to insert linefeeds at points beyond a certain width -- messy, but it would work.
View 4 RepliesLimit Child Forms To A MdiParent?
Mar 20, 2012I have this function
Private Sub createChildForm(ByVal winForm As Form)
'Take a form and set app as its parent form
winForm.MdiParent = Me
winForm.Show()
End Sub
When some one wants to view the "About" form, it's called like this:
createChildForm(New f_about)
But my function doesn't stop them from creating an unlimited number of about windows and I need to put that limit to one form.
For example, I will have a login screen, but I don't want them logging in over and over again in different accounts because my subroutine doesn't stop a form from being created/opened more than once.

View 2 RepliesSql Server - Linq - Limit List To 1 Row Per Unique Values Based On Value (minimum) Of Single Field
May 3, 2012I have a stored procedure (I cannot edit) that I am calling via linq.
The stored procedure returns values (more complex but important data below):
Customer Stock Item Date Price Priority Qty
--------------------------------------------------------
CUST1 TAP 01-04-2012 £30 30 1 - 30
CUST1 TAP 05-04-2012 £33 30 1 - 30
CUST1 TAP 01-04-2012 £29 20 31 - 99
CUST1 TAP 01-04-2012 £28 10 1 - 30
I am trying to limit this list to rows which have unique Dates and unique quantities in LINQ. I want to remove items with the HIGHER priority leaving rows with unique dates and qty's.
I have tried several group by's using Max and order by's but have not been able to get a result.
Is there any way to do this via linq?
EDIT:
Managed to convert brad-rem's answer into VB.net.
Syntax below if anyone needs it:
returnlist = (From p In returnlist
Order By p.Qty Ascending, p.Priority
Group By AllGrp = p.Date, p.Qty Into g = Group
Select g.First).ToList

View 2 RepliesForms :: Drop-down List Combobox?
Mar 23, 2010I have created a drop-down list box that holds 8 numbers representing a month span (3, 6, 9, 12, 15, 18, 21, 25 months). In order to prevent users from typing just anything into the text box above the combo box, I changed it to a drop-down listbox. The other requirement that I was hoping to implement was for the user to be able to type a number, after which the selection would jump to the appropriate item (i.e. the user types in '1', and the selection jumps to 12). This partially works. It will jump to 12, for example, but immediately after the user types the '1', the Selected Index event changes. The user cannot scroll down or up after typing in a number.
