If Not m_Batchs Is Nothing Then[code]...
I have this list view (which is working fine) and i want to find an efficient way of populating it in a specific order, ie by date, by identity etc.
I know i can use linq but as i understand this is inefficient. If m_batchs is a large list of objects then i will looping through this list many, many time (as linq behind the scenes loops through the object collection).
You can set listview items in a-z order and z-a order but how to set listview items in arbitrary order?
View 4 RepliesHow can I add all the items of a specific column of a listview. For example I had a listview of a class like:
name............... surname............... age
------------------------------------------------
asdsa..............asdasdasd................21
sadsad..............asdasdasd...............23
sadsad...............adasdasd...............24
I just want to add all the numbers of age column so I can find the total sum of ages of the students. I want, when I clicked my button It makes my textbox's text = 68 for this example.
I'm trying to drag an item between two Groups in the same ListView called 'listTasks'.
Private Sub listTasks_ItemDrag(ByVal sender As Object, ByVal e As ItemDragEventArgs) Handles listTasks.ItemDrag
listTasks.DoDragDrop(listTasks.SelectedItems, DragDropEffects.Move)
End Sub
Private Sub listTasks_DragEnter(ByVal sender As Object, ByVal e As DragEventArgs) Handles listTasks.DragEnter
[Code]...
With listTasks.PointToClient(New Point(e.X, e.Y)) you could use listTasks.GetItemAt(p.X, p.Y) to get the ListView item you're over. Is there something like this for Groups? Or perhaps a better way to determine what group is the target of a drag-drop?
i am using a webclient.downloadstring to get the string lets say this is this
Item1
Item2
Item3
Item4
and i wanta send each line to its own specific item...
I have a combo box bound to a datasource. I need to change one combo box (of many) to order the items in descending order.I'm guessing I could order the collection in the dataset, but that will mean all my combo boxes will be reordered?
View 2 Repliesi have lines like this
1.0 28 Blue [B3-T1 ] (2 16.00 43.0) 10000 -10000 72111 23275
1.0 28 Blue [B3-T2 ] (2 17.00 43.0) 11000 -10000 72111 30275
1.0 28 Blue [B3-T3 ] (2 16.00 44.0) 12000 -10000 70611 23275
[Code].....
Let say the columns that i highlighted is X and Y. I have to arrange the small Y first which is -10000 then arrage big Y which -11000 then arrange again samall Y followed by big Y. Here i only have -10000 and -11000. but let say i also have -12000 so i have to arrange -10000 first then -11000 then -12000. But i also have to look at X column. If let say x value is same next line so it should side by side like i higlighted the two row.
the lines should be identified by [B3] as it will be one group. Can we use IComparer methode here? How to arrange the lines in order thet i want?
I have a bunch of buttons on a form and when the person presses TAB I want the focus of the controls move in a specific order.
View 3 RepliesI'm making a keyboard test that will test to make sure each key, in a specific keyboard layout, is working correctly.
Each key, with the exception of the first, will be disabled by default. I need to have the tester press the first key (Escape) and if it works, disable that key and move on to the next, (F1). This process will repeat until all the keys have tested.
The dilemma I have is figuring out how to test each keystroke, in order, without making a huge nested if statement.
The only method I could think of, at the moment, was to check the Enable property of the control and then check for the correct keystroke. But, again, doing this would make a huge mess.
Private Sub Form1_Load(ByVal sender As Object, ByVal e As EventArgs) _
Handles Me.Load, Me.FormClosing
MessageBox.Show("form_load")[code]....
While closing the form I observed that the Form1_FormClosing method is fired first, and then Form1_Load second. Why is this order chosen? Why doesn't Form1_Load get fired/entered first, and then Form1_FormClosing second?How does .NET choose which method to fire first, of the two that handle the same event?

I have a listview with 6 columns. The first, hidden, is a key value. The other five are FirstName, MI, LastName, Gender, and CurrentGrade. When I go to populate the listview, I pull a datatable and do this:
For Each dr As DataRow In dt.Rows
Dim lvi As New ListViewItem(dr("StudentKey").ToString)
For i As Integer = 1 To 4
lvi.SubItems.Add("")
[Code] .....
But when the form loads, I get the MI in the FirstName column, the First Name in the LastName column, the LastName in the Gender column, and the Gender in the CurrentGrade column. The MI is blank. I've run it in debug, and the correct values are in the correct subitems. But for some reason, when the ListViewItem is added to the ListView, the subitems get all jumbled.

I want to rearrange a list of items in different orders for few times; ie: the 2nd in the list becomes the 1st & the previous 3rd becomes the 2nd, ... then the Last one becomes the penultimate one.In the next round, the 3rd of the original list becomes the 1st & the 4th of the original becomes the 2nd and so on. (That is, each item moves one rank above & the Top one goes to the Bottom)Given below is an example.Here, I took only 6 items & rearranged for 5 times only. (I should be able to use several Items and to rearrange for many times).The Original List:
(1) Alpha, (2) Beta, (3) Gamma, (4) Delta, (5) Epsilon, (6) Zeta
2nd List:
(1) Beta, (2) Gamma, (3) Delta, (4) Epsilon, (5) Zeta, (6) Alpha

so I am working on a program with items entered into a listbox. Then when the user clicks a button it will randomize the listbox items in just a random order obviously. I have tried adding it to an array and everything but I ended up just having to start over now because I couldn't find a solution. I can save the contents and everything I know how to do that it's just randomizing the items that I am struggling with. I have searched high and low and have yet to find a conclusion to my problem.

I have a listview1 with two columns Name and Age. This code when I click on a listview item it is higlited and then i click on textbox1 it will remove the row and place the text in textbox1 and textbox2.
