I'm working with VB 2008 and I have a problem when using multiple listbox. For instance, I have 3 listboxs (StudentID, Surname, GivenName) and all of them are related to each other. I would like to allow users to remove a specific item by typing StudentID. Then StudentID, and two related data Surname and GivenName will be deleted also.
View 2 RepliesI am looking to remove an element from an ArrayList using a query, E.g. DELETE FROM arraylist WHERE (0) = "User1" (Where (0) is the index of the second dimension).
Code:
Dim Users As New ArrayList
Users.Add({"User0", "Details"})
Users.Add({"User1", "Details"})
Users.Remove("User1")
The reason I am looking for a query way to do this is because I will not know what the second dimension value will be.
I have 2 listboxes on my form.Listbox 1 - populated with "available" field namesListbox 2 - populated with "selected" field names.There cannot be the same field name in both listboxes - it's either one of the other.The logic I was going to apply was to populate Listbox 1 with every field name ... and then as I populated Listbox with the field names which the user has already selected, remove the corresponding item from Listbox 1.

View 2 Repliesthis is going to be hard to explain but ill try. Question 1. Ok i have a list box with a few items, What i want for this example is to click a button and it will start on the first item and do: MsgBox ("this is item blah blah blah") then after that it will go to the next item and do the same and then the next and so on untill all have been done. The "blah blah" should be the item so if item was to say "hello" then the msgbox would say "this item is hello" I know this would be a lot of msgboxes to close, like if 50 items then thats 50 msgboxes to close, this is just for the example.
Question 2. Ok this is where ive tryed to learn but find it really hard (multithreading) Im wanting all to be multithreaded so all work at the same time, ive tryed a few times but the only way i see it is having a **** load of subs, like if i want it to use 10 threads then ill have to add the same code 10 times or somet, im not sure.
i have attempted all this and failed big time as my way was to get the first item and use that then remove it from the listbox BUT... with it being quite fast the 2nd 1 and 3rd 1 used the same item befor it was removed and to be honest i dont really want them removed. so my attempts took like 2-3 days that was a waste of time really. I Know this is a lot to ask but im in real need of it and these 2 things have driven me half mad.
Im working on a program for a class project and part of it im required to remove one selected item from a listbox, in my case "lstCart" i have to first check if there is an item selected by the user, in which case i have to remove that item. Secondly, if there is no item selected i have to display an error message telling the user that they have not selected any item to be removed. Can anybody help me with this code? Ive tried a sort of nested if statement but that didnt seem to work very well.
