Remove Items In One List From Another List?

May 2, 2012

i am writing a program that reads a excel report from accounting software with our weeks orders on... so basically the program reads a list of around 100 items which all works fine.I also have a database that holds info on each item, when the excel sheet is parsed the software checks to see if any new items have been added to the list that are not on the softwares database. this is where i am having the issue.I have two lists: ItemsOrdered & ExistsingItems.

All the items ordered this week are in ItemsOrdered and all the items not in the items in the database are in the ExistsingItems list. using these two lists how can i find items that are in ItemsOrdered but not in ExistsingItems.

Determine If Property Is Generic List<of T> Via Reflection And Loop List Items

Oct 1, 2009

I'm looping all the properties in an object via reflection:

For Each p As PropertyInfo In values.[GetType]().GetProperties()
If p.CanRead Then
'Do stuff
End If
Next

how to determine whether the property in question is a generic List(Of T)? If it is I need to loop the list itself.

I've experimented with GetType and TypeOf but have not managed to get anything working.

To clarify, I want to keep this generic. I do not want to specify the type of T, I need to loop the list items and call the ToString method on each item. T could be one of a number of different types (application specific reference types). Is it possible to do this without specifying types?

Placing Selected/unselected Items In Checked List Box Into List Boxes?

Mar 16, 2011

This program is supposed to allow the user to check items in a checked list box. If the item is checked, it goes into the Completed List Box on the right. The program then adds the unchecked items to the Pending list box on the left. I keep getting placement values (e.g. O,1,2) instead of the strings (e.g. "Key Returned") in the list box results (see photo attached)

Public Class frmCheckOut
Dim i As Integer
Dim cleaning As String = "Cleaning Inspection"
Dim damage As String = "Damage Repaired"

Shuffling Items Inside A Movie List / Need To Delete Half List

May 16, 2011

Another program I am working on for fun, I am basically shuffling a list inside a listbox, what I want to do is delete the rest but not sure how to go through with that. At the moment I have this: [code] Just contains the code, declarations outside weren't included.So anyway, once clicked, it will call on the function to basically shuffle in a for loop, I was wondering if I should (or how should) create another function and call it in the click button or have just a loop in the click button so it deletes half the list. What I am doing is I have 20 list of items, I want the program to shuffle the items and then deleting the lower 10, meaning, if I had 10 items and wanted 5 top, I'd want: 0, 1, 2, 3, 4 and deleting 5, 6, 7, 8, 9.

Remove Items With No Text?

May 27, 2009

I have a serious problem, I have 3 listboxes, and all three of them will get items that contain no text. My problem is that I have the same code for all three listboxes to remove "" from the listboxes except one listbox will not remove the items. I've tried countless times to remove the empty items and failed. So how do you see if a listbox's item contains no text?

Comparing An Item In A List Against Other Items In The Same List In .NET?

May 30, 2011

I have a List(Of MyObj), and I want to iterate through that list and compare each element to all other elements in the same list, excluding (if possible) the same element. I have a solution that works, but it's slow and uses double For loops. It may possibly have also summoned Cthulhu from his sleep. This below is a sanitized version of what I have:

Dim MyList As New List(Of MyObj)({Obj1, Obj2, Obj3, Obj4, Obj5, Obj6})
If MyList.Count > 0 Then
For i = 0 To (MyList.Count - 1) Step 1
