Combobox.items.add - Combobox To Have A List Of Choices From A Table In A Db

I'm making a combobox on a form. I want the combobox to have a list of choices from a table in a db. The two columns are a String and a Date. I want the date column to only show the year. I'm hoping I have the code right as it is above, but I'm not positive I've done the whole date thing right.

May 24, 2012I am disabling line items in a combobox I have based on various test conditions (see code below). The problem is that when I first open the combobox my method below isn't getting called. It only gets called when the mouse hovers over each line item.
This is resulting in the list looking very different before/after a hover (see png file for a before/after picture).
how to show the list disabled on open?

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.
VS 2010 Checking Items In A List?
Mar 13, 2012I have a checkedlistbox with numbers in it and I'm trying to load a list of numbers from a database and check all of them (they should all be in the checkedlistbox).
I was trying to do this by loading all the values into a separate listbox using my own subroutine (I know that part works) and then finding the corresponding item on the checkedlistbox, like this:
Dim ItemName As String
For Each item In ListBox1.Items
ItemName = ListBox1.GetItemText(item)
If CheckedListBox1.Items.Contains(ItemName) = true Then
CheckedListBox1.SetItemChecked(CheckedListBox1.Items.IndexOf(ItemName), True)
End If
Next
End If
But this doesn't work: It never returns a match, even when the item is definitely on the list. How do I make this work?

View 7 RepliesVS 2010 Storing Data Along With List Box Items?
Sep 19, 2011What I'm trying to accomplish is first of all, adding items in a list box, but while doing so, store data into that item so when the user clicks on it, the data will be brought up into the correct text boxes.
My idea on how this will all work out has to do with array lists. I'm thinking each time an item is added to the list box, an array list is generated containing all the data from the text boxes. The array list would be named as the text of the list box item.
So then when the user clicks on one of the items, it can find that array list easily because of the selected index, and then update the text boxes with the data.
Is the way I'm thinking of possible? If not, or if there is an easier what, what would that be?
