Delete The Selected Name From The List?

Nov 6, 2010

I've been working on a program lately. On the form load it loads a list box with a list of names from a .txt file. It's a sign in form, so when people click their name then the button it will write to a .txt file their arrival time, and the folder is their name. I can make it do it one at a time, but that's so inconvenient. I have the list box set so it accepts multiple selections, but I need to make it write the time for everyone.

how to delete the selected name from the list that would be extremely helpful, that way the person isn't signed in multiple times.

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.

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)

Datagridview Selected Row Delete When No Pkey Is Set

Feb 9, 2011

So i'm steadily learning more about table adapters and SQL commands. One of the latest things i'm trying to figure out is how to correctly delete a datagridview row and have it update the database when no Pkey is set on the database. I'm sure i'm missing something simple, all i've managed to do so far is delete everything Obviously when no pkey is set the table adapter wizard doesn't generate the delete statement.
