VS 2010 Linking 2 Table To A Checkedlistbox
Jun 14, 2010
I Have a problem with trying to get a checkedlistbox to work the way i want it to... Here are the 3 tables that i'm using. The links are shown in colour.
[Code]...
I have a checkedlistbox in a windows form: A Name textbox is linked to The Name in the Usertable
1.The DisplayMember in the checkedlistbox in the Area (Text) from the AreaID Table. This bit Works.
[Code]...
2.The ValueMember need to be the AreaID from the UserAreaTable
I need to do it this way because it allows me to add multiple areas to users, and add new area's without having to change the forms.

I have already made my GUI with multiple forms using VB2010 and made buttons that would open and close them (me.hide and form#.show)My problem is how could I use a variable I've computed and displayed on a sub-total (cashier of sorts) to be used on the main form where it would display the bill on a listbox?Here's how the button works to compute for the item sub total
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim cstotal As Integer

How do I get the set of checked items in a checkedlistbox when an item is checked or unchecked, given that ItemCheck event occurs before the check state is actually updated? (The SelectedIndexChanged event won't work in my case.)

Having 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?

Ok, I have a CheckedListBox that I open as so.

However, the value of the count is always 0 when the form closes after clicking OK.

I 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.

I'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.

I 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.

I do this in Oracle databases just in a snap, but now I have to do it in VB using ADODB and I don't know how to do it.
I have two Access 2007 tables. Table A contains: Col1 (text), Col2 (text), Col3(date), Col4(amount), Col5(text)
Table B contains Col1(date), Col2(amount) What I need to do is to insert into table B the records of table A (col4 summed) grouped by date of table A. The date is a variable contained in a text box so it cannot be hardcoded into the SQL statement.

I've recently decided for my VB final that I'd like to tackle something my professor and I discuss constantly; portable game server apps.
What I'm wanting to do, essentially, is create just a rudimentary programme that allows you to check the server status of either the north American or European servers for the game Rift and just (instead of opening your default browser, which I know how to do already) displaying the info in a listbox inside the programme itself.
The information I have to work with (aside from the obvious direct .php link to the web page) is two separate .xml links that contain all the information that is contained on their webpage. I could easily just turn these .xml files in an access database but I want something dynamic rather than static, but I honestly have no clue of how to turn this info I have into something I can actually use in my programme lol.

I'm creating a system (for a project) that is based on a vet.I want to create a combo box that has a list of different animals (e.g. Dog or Cat etc.)and when an animal is selected,a group box, with loads of checkboxes inside appears. Then the user can tick a check box (a vaccine to be given to the animal) and the record is saved to a database.I have hard coded this to work, but I want a more sophisticated code set, that links to SQL so that when a new vaccine is to be added, I would only need to add it in a table, in the database. I don't know where to start for this could any one give me a nudge in the right direction?

What are the main functions needed to create a .dll file in vb.net which needs to be Explicitly linked i.e at run time to an application Plz post me an equivalent code snippet in VB.Net
Explicit run-time linkingDLL files may be explicitly loaded at run-time, a process referred to simply as run-time dynamic linking by Microsoft, by using the LoadLibrary (or LoadLibraryEx) API function. The GetProcAddress API function is used to lookup exported symbols by name, and FreeLibrary — to unload the DLL.
