VS 2010 - Removing Items From A List (of T) With For Each
Dec 14, 2010Public Structure ReportOrderType
Public ReportName As String
Public ReportDate As Date
Public SaveFile As String
End Structure
[Code] ....
Basically, I have a list of reports. In one place they get ordered, and later on the program looks to see which ones have come back -- see if the .SaveFile exists on disk. If it exists, then that report gets processed, and then I want to remove that item from the list of reports-on-order. However, I get an error message back that by doing the .Remove(R), I've changed the list itself & things won't go well with the rest of the For Each loop, which makes some sense.
When I get to this routine, the list of ordered reports will be something from a couple of dozen or less, and some number of them (perhaps zero, perhaps all, probably a few) will exist & be processed & then should be removed from the list. How should I go about accomplishing this? This is my first time working with List(of t) as a Visual Basic tool; everything I've used in the past has been with arrays, and I can do this there.

Removing Items From A List Box After Setting The DataSource
Sep 29, 2010I have a small requirement and that is as follows:
I am populating a ListBox using stored procedures and the ListBox is populated as follows:
lstItems.DisplayMember = "emp_name"
lstItems.ValueMember = "login_id"
lstItems.DataSource = accessFunction.getEmployees
The ListBox gets populated correctly. After it is populated, i have a CommandButton and on the click event of the button, i want to remove selected items from the ListBox. So in the click event of the CommandButton, i have written the following code:
lstItems.Items.Remove(lstItems.SelectedItem)
After selecting an item from the ListBox and when i click the CommandButton, i get an error as "Items collection cannot be modified when the DataSource property is set".
how i can delete items from the ListBox.
VS 2008 Removing Items From List Of Class?
Jun 12, 2010I've searched on the Internet and I can't find a solution to this simple problem. I've also looked on Microsoft's MUCH improved MSDN site and haven't found a solution, so here it goes. I'm trying to remove an entry from a list of class and it doesn't get removed. Here's a sample of the code I'm trying: (I renamed the class and variable names to make it a simple example)
Dim lstClass As New List(Of TheClass)
Dim mClass As TheClass
I tried this first
mClass.filename = "The Entry to Delete"

Forms :: DataGridView DataError Exception When Removing Items From Bound List?
Nov 2, 2011I am using a DataGridView bound to a BindingSource which is itself bound to a List of objects. This all works well until I remove objects from the list. If I am scrolled down to the bottom of the DataGridView and then remove a bunch of items from the list it is bound to it generates a DataError exception because the length changed and the rows I am looking at no longer exist... I changed my code to handle that error, but now instead of popping up a message it SLOWLY erases the data in each of the newly invalid rows at the end of the table (I think each time it does one it generates a new DataError, which is why it is so slow).
How do I prevent this? I want to be able to dynamically (and programmatically) add and remove items from the table without the possibility of this error... I assumed this would be handled automatically as part of the data binding process but I guess not.

View 4 RepliesVS 2008 List View Items Flickering?
Sep 30, 2010I have a listview (details) with owner draw set to true (so i could make rows alternate in color, looks cooler) which basically contains items and subitems whose texts reflect status info that updates constantly
the problem is, sometimes (if the task runs quickly) the status changes really quickly, and as a result, listview items "flicker" for a millisecond no error, no real problem, its just really annoying and makes the program look less professional.
Is there a way to make the listview not flicker? Or maybe there is a way to make it so that the listview doesn't process too many drawsubitem calls during the same time interval? or maybe there is some customized list view out there that does the trick better?
NOTE: i tried with owner draw set to false. it flickers less, but still flickers. same problem :S
Also NOTE: i am not making cross-thread calls. i have 50 items in the listview and 4 colums, mainly the last 2 subitems change.
