Open A File And Change Stuff, Then Close It Without Saving The Changes, The Events Still Fire?
Mar 17, 2010I am using about 5 different filesystemwatcher routines total. I am using the following
filewatch.NotifyFilter = NotifyFilters.CreationTime Or NotifyFilters.LastWrite
AddHandler filewatch.Created, AddressOf addfile
AddHandler filewatch.Changed, AddressOf addfile
filewatch.EnableRaisingEvents = True
However, there is one problem with it... whenever I open a file and change stuff, then close it without saving the changes, the events still fire. I am opening excel workbooks in code, then use xlsWB.Close(SaveChanges:=False) to close them, and the event still fires, where the file isn't really changed so it should not fire.
Saving CheckedListBox's Items, Retaining Checked State?
Jun 11, 2011I'm trying to program a personal project, but I've hit a bit of a bump in the road.I've got a Button, a Textbox, and a CheckedListBox; when the button is pressed, whatever is in the TextBox is added to the CheckedListBox. However, when the form is closed and reopened, all of the CheckedListBox's items are no longer present. My CheckedListBox's name in the code is ZapList.
Can someone assist me in, not only saving all of the CheckedListBox's items, but retaining whether or not they were checked as well as the order they were in? I've run out of hair to pull (figuratively) and I really don't want to quit this project, too much effort has gone into it and I'd hate to see it go unfinished like my numerous other projects. :icon_cry:

I have a start equivalent button then I just need to the actual menu.

VS 2010 Upgrade From 2008 To 2010 - Now LINQ - IntelliSense Is Not Working For LINQ Stuff
Apr 20, 2010I just upgraded a project from VB 2008 to VB 2010. Before, the project did not use LINQ. I have started implementing it. So, I have updated the target framework from 2.0 to 3.5, and added a reference to System.Core, and imported the namespace System.LINQ to the entire project and also imported System.Data.LINQ into the form I'm working with (because it was not available in the list for Imported Namespaces in the references tab).
It's not throwing any errors now, but my IntelliSense is not working for LINQ stuff.
For example... I write this:
[CODE]....................
Then, if I type S. on the next line, the IntelliSense doesn't grab what it should for S (Only get Equals, GetHashCode, GetType, ReferenceEquals, and ToString, instead of the options I should get like Count, First, FirstOrDefault, etc...). If I Type S.First. then its the same thing, no IntelliSense that lists the available fields for S, just the standard options (Equals, GetHashCode, GetType, ReferenceEquals, and ToString). I should be seeing my column names in my table when I type S.FirstOrDefault.
So any ideas what is going on? When I type the code, for example, MessageBox.Show(S.FirstOrDefault.FirstName), it works perfectly. But it doesn't change the casing of the text (so it would read s.firstordefault.firstname) and no intellisense while doing it. But no errors. BTW - Everything works perfectly when creating a NEW VS 2010 application, it's just my projects upgraded from Visual Basic 2008 that have this issue.

VS 2010 : Programmatically Check Item In CheckedListBox?
Jun 12, 2011Having some issue trying to programmatically check items in a CheckedListBox.What i am trying to achieve:
1. Pull Staffnames from database
2. Separate each staff member via delimiter
3. checked = true for each item in StaffCHKlist where staffnames = existing StaffChKlist item
i have had a few goes, but cant seem to achieve, this is where i am currently at:
Dim sl As String = ds.Tables("Consignment").Rows(0).Item("StaffName")
Dim tokens As String()
tokens = sl.Split(",")
[code]....
which errors with:
"List that this enumerator is bound to has been modified. An enumerator can only be used if the list does not change."
I have been trying to understand, would programmatically checking an item in a checkedlistbox be classified as list change?

VS 2010 Combobox Selection Alters Checkedlistbox Contents
Feb 23, 2012I am new to the forum and to VB, and not great at coding in general.I am learning, and this site as well as others have helped me get farther than I ever imagined. Second, my project is purely for my benefit, so I can learn.There is no corporate or school related goal here, just trying to learn.So the title is a summary of what I want to do. I have a form with a combo box that has five different choices, and below it, a checked list box. What I want is the collection inside the checked list box to change depending on what I select in the combo box above it.For instance, I have room 1 - 5 in the combo box, and the the checked list box below it, I have the furniture associated with that room.The eventual goal is to have this form populate a database, that allows the checked furniture to be recorded in a record.
I assume I need to use a db, such as access, to list the "furniture" in each room, and have a different table for each room, where the combo box selection will populate the checkedlistbox from the appropriate tables contents.I need a step by step on this, because I am a bit of a brick. Most tutorials are also done in VB 6 or VB 2008, and there have been steps missing in association to VB 2010.
VS 2010 Delete Multiple Items From CheckedListBox And Array
Jun 19, 2010I'm working on a To Do List program of sorts. I currently have a CheckedListBox on the form with an Add Button and a Delete Button. I send the items to an array and then use that array to fill in my CheckedListbox. This all works.
I wrote the following code to delete items:
Dim summarylistboxindex As Integer
summarylistboxindex = SummaryListBox.SelectedIndex
MonkeysTasks(summarylistboxindex) = String.Empty
[Code]....
I use a variable called INTCOUNTER to keep track of my position in the array.
My question:
How can I use the second piece of code that deletes multiple items at once from my CheckedListBox AND delete the corresponding entry in the array?
ie if my checkedlistbox items were Apple Orange and Banana
I want to delete Apple and Banana at the same time and then remove them from Fruits(0) and Fruits(2) at the same time they are deleted from the CheckedListBox.

.net - Populating One Checkedlistbox With Another (checkedlistbox)?
Mar 24, 2010I am having difficulties populating a checkedlistbox (CLB) based on the selection(s) made in another. It should also be noted that I have a "Select All" checkbox at the top that checks/unchecks all of the items in the first CLB. Here's the code:
[Code]...
The first CLB is populated with an arraylist of values on the button click event. Based on whatever is checked in the first CLB, corresponding values from an arraylist of structures should fill the second CLB.The following code partially works until the "Select All" checkbox is clicked at which point if other values have been selected before "Select All" is checked, the second CLB is filled with the correct number of corresponding values BUT only those of the most recently selected item of the first CLB instead of all of corresponding values of all of the items that were not already selected.
