IDE :: Maintaining Array's Order When Deleting A Listbox Item

Jul 24, 2009

I have made an employee list and linked it to an Access database. The initial problem I was having is that in my program I had to link their ID's and names so if you click on an employee in the listbox, his or her's ID would automatically display in the textbox below. Since I did not know how to do so, I decided to make an array and store the ID and names separately while the listbox is being compiled. And so, the form became linked and adding became easy to code.But my problem came in deleting an employee. When deleting the name should be removed from the list, but this is where the order of the arrays messed me up. How do you maintain the order of the array? Here is the code I used. I dimmed 'count' as an integer and it is responsible for keeping that order.[code]You will see Staff_CodeTextBoxes etc. and info_Staff_CodeTextBoxes. etc.These text boxes (not visible to the user) are responsible for holding the data while the array takes the data from it, or adds it's own data to it.

Deleting Duplicate Lines In A Text File Using An Array

Sep 27, 2009

I am adding line entries in a .ini file. The problem is, I am creating duplicate lines in the file, which I do not want to do. I searched this issue online, and the consensus is to use an array, loop through for duplicates and create a new file. However, being so new at this and teaching myself how to code no less, I am at a dead end. This is not a school project, it is something I am doing for work on my own time. I have all of my code done for the program except for this last step.

VS 2010 Deleting Multiple Items In A Listbox?

Apr 23, 2012

basically i had this problem before which i fixed with this code!

'REMOVE TIME
If ListBox1.SelectedIndex <> -1 Then
Dim Box As MsgBoxResult = MsgBox("Are you sure you want to remove this time?", MsgBoxStyle.YesNo)

[Code]....

It worked perfectly, all ive done to my code since is change the way the listboc is loaded / saved, it now comes from a .txt in My Documents rather than the C drive.

It now only deleted the top value of the group selected int he listbox and not all of them as it did before.
