How is it possible to delete all the items from a ListBox that have the same extension? This is in particular to video files that have have extensions of .mpg, .modd and .moff. I can populate the ListBox with just the .mpg files but I would like to know how I can remove the other file types should I put the whole lot in.Also, presumably using similar coding, it it posssible to highlight all lines with a particular extension?

VS 2008 Sort Listbox, Save Items And Delete After Date

Apr 13, 2012

I am making some kind of calendar where I can add tasks, so I can easily organise my tasks. For it to complete, I have 3 things I can't figure out how to do it:

1. When I launch the program, I want the items in my listbox to be sorted alphabeticly.

2. I want to save the items in the listbox, so if I close the program and reopen it the items are still saved in the listbox.

3. The items in the listbox all start with a date, fe. "13-4" for today. If that date already passed I want that item to be deleted.

Listbox Items Colour - Two Types Of Items Populating In A Listbox (checked Listbox)

Apr 28, 2009

I am using VB.NET (version 2008). I have two types of items populating in a listbox (checked listbox). For example: lets say one is type "A" and other is "Type B". Their names maybe same so if the user sees those items in listbox then he won;t be able to determine their type until he click on them and checks out its properties. I wanted that I add each item to listbox and colour them so that blue for example means type "A" is there and red means the other. So this way I will be able to know at a glance that how many item of what type is present. I guess it may not be possible to do that in a standard checkedlistbox. I am also using component factory's krypton controls which enhance the gui of an application. But I dunno if I can progress using that.

Add, Edit & Delete Items In A List Of Geographical Coordinate In A Program?

Aug 21, 2010

In my project, I want to use Coordinates of a place (eg; London) which is selected from a list of several thousands of coordinates of places.

I thought of using comboBox / ListBox to display the list of the coordinates of places.

I want to know how to make this "editable"; ie: anyone using this program should be able to Edit / Add / Delete a coordinates of a place. And the newly added Place should be saved so that he/she can use it whenever it is needed.

Directory Items TO Listbox Items?

Mar 17, 2009

I'm making an application that does some stuff involving the given subject, so this is very crucial to the completion and efficiency of my application.What I'm in need of today is simple (well, "seems" simple). I have one listbox that I want to populate with directories file's names. I don't mean the files inside the directories, but the names of the folders inside the directory.So, I have "c:empdog", I'd click on my button or whatever and search for the directory and I choose "temp", said listbox would show "dog".

UPDATE: Oh, BTW. It doesn't HAVE to be a listbox, it can be anything (IE: Textbox, Labels, Etc.).

VS 2005 Check Grid Items If Checked ListBox Items Checked?

Aug 21, 2009

Why is this code having the opposite effect? If It's checked in the checkedlistbox it's not check in my view, if it's not check in my checkedlistbox it is checked in the grid.

EDIT: More specifically. The CheckState.Checked is always the opposite. .Checked means it's not checked.

Datagridview Delete Existing Items

Nov 1, 2010

I have a datagridview i use to load alot of klients into a combobox. The values of the datagridview is a connection to a MySQL db.

What it's suppose to do, is to: When clicking the combobox, it should make a list from the datagridview, getting all the names from the klients.

My problem is that it gets dublicated, and will use to much memory at a moment.

I've tryed to check if the item it was about to add allready existed in the datagridview, if it was, it shoudn't add it again, however my code failed, and I'm having huge CPU and RAM useage when running this problem for more than 30mins.

My code:

Private Sub loadCustomers()
SQL = "SELECT * FROM kunder;"
Try

[Code].....

The code above is only checking for dublicated in the combobox, And I want the code to also check for dublicated items in the datagridview.

Or a way to clear the datagridview right after the items are inserted into the combobox?
