Determine And Obtain The Value Of The Item That Has Been Selected In The Combo Box?

I am having difficulty using the selected value of the combobox while calling it from the ok button click event procedure. While debugging in the Ok button coding none of the values are their, but for the comboxbox coding it appears that it is working properly.I made a seperate funciton to handle the combobox, could this be my error?

Using VB.net 2010 i am trying to figure out if an item was selected or not. Reason being is that if the user clicks on an item and pushes a button then everything works just fine. However, if the user selects an item and then clicks on a blank spot on the bottom of the listview and then clicks the button then it crashes.
My code is this:
If (lstMaster.SelectedItems(0).SubItems(1).Text) Is Nothing Then
MsgBox("test")
End If

I want to add a context menu to a datagrid in VB2008 and I need to find out which menu item the user selected.
I don't want to use the ContextMenuStrip that's available in the toolbox since it doesn't allow for dynamic placement depending on what row is active in the grid (I haven't found a Top and Left property in the ContextMenuStrip)
Here's what I've got so far, I'm aware of the fact that the MsgBox uses a non-existing property, it is meant to show my intention.
Given the available properties in the ContextMenu object, I would think that there would be something like a SelectedItemCaption property but a search of the object tree yields no results.
dim grdContextMenu as ContextMenu
grdContextMenu = New ContextMenu
grdContextMenu.MenuItems.Add("Insert")

Visual Basic Express Edition 2008 Problem. I have a Combo Box containing Country Names "New York" & "New Zealand", when "New York" is selected it shows the time and date of New York in label1 on the form and the time is updated every second by the timer, but when I make another selection by selecting New Zealand in the combox dropdown list then New York's time updation is stopped in label 1 and only New Zealand's time is updated in label 2. Why the timer control stops functioning for the first selection after we make a second selection in the combo box. I want that time for both label 1 country as well as label 2 country updates simultaneously on the form. My code is as follows:I have added 2 label controls and one combo box control on the form and following code.[code]Can any one advice me how all countries selected in the combo box one after other are dispplayed with updated time every second?

I have a combobox that drops up instead of down. I'm setting the selected item to the one on top of the list. I'd like to move my mouse pointer to point to it, so that the user that wants to click on that item doesn't have to move his mouse. I found how to move the pointer, it is with this command:
Windows.Forms.Cursor.Position = New System.Drawing.Point(x,y)
but I need to know how to get the location of the selected item in the combobox.

I have a property called ReplacementTo and I set a value to it based on the selecteditem from the combobox, like this:
classEquipmentItem.ReplacementTo = cmbReplcmnt.SelectedItem.ToString
Now I can't use cmbReplcmnt.Text because what I actually need is the value of that SelectedItem
So problem is, if the user leaves the combobox as blank, it throws a null exception.I decided to use the IIf function then:classEquipmentItem.ReplacementTo = IIf(IsNothing(cmbReplcmnt.SelectedItem.ToString), classEquipmentItem.ReplacementTo = "", cmbReplcmnt.SelectedItem.ToString)
Unfortunately I still get the error I tried using a Try-Catch for it and it worked, but I don't want to rely on the Try-Catch, so I was wondering is there a another way to work this through?

I am creating a program that allows a user to view a list of foods in a combo box, add that food unto a list box, and adds all of the calories of that food together. When the user highlights their select food, the program automatically shows the amount of calories for that particular food in a text box. The program is getting the food and calorie information from an access database. I managed to get all of the food calories to add up properly, however, I ran into a problem. Sometimes, well, most of the time, when I select certain foods from the combo box, the program automatically reselects another random food, usually a food that begins with either an A, B, or C. Also, the other random food that the program chooses usually has the same amount of calories as the food I originally wanted to choose. I have over 6,000 items in the database. I don't understand why this is happening. This is what my code looks like for the button that adds each food to the list box:
Private Sub Button4_Click(sender As System.Object, e As System.EventArgs) Handles Button4.Click
Foods_Selected.Items.Add(ComboBox1.Text)
Static i As Single
[CODE]...
And this is what my code looks like for the button that adds all of the foods together:
Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
Dim x As Single
Dim TotalCalories As Single
[CODE]...
I have no idea what to try. It's like the program just skips over random foods, even though all of the information for them is in the database.

I'm having some difficulty with a sorted & grouped listbox in WPF vb.net 3.5 that has an items source bound to an ObservableCollection.
What I want to be able to do is to retrieve a piece of data from the ObservableCollection items source depending on what item in the listbox the user has selected.I've almost got it working but because the listbox is sorted it does not match the index of the items source.
[code]...
As I previously mentioned, because the lstBox is sorted and also grouped the index's don't match up.Does anyone know how I can get the correct information I want from the List Source depending on the selected item in the list box?

Just started on vb.net

I've tried to code it in a logical way as possible but it just doesn't works except for the "wtf" so i think that overall my code is correct but the way i want to retrieve the selected item from combo box is wrong.

Ok, so I have a listview on one form, and when a button is pressed it opens up a new form with the contents of the selected listview item and it's subitems in a series of textboxes. The user can then change the data in the textboxes and either press save to make the changes or cancel to close the window. What command would I use to change the selected listview item and subitems to whatever is in the boxes?
this is the code that populates the boxes:
Private Sub Form_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim appeditcontents As String = main.passlist.SelectedItems(0).ToString

I am making a password program that remembers what the password is for and what the password is. I have two listboxes: 'listbox1' for what the password is for, and 'listbox2' for the password. I also have a remove button. I would like it so when you press the remove button, the selected item in listbox1 is removed and the password in listbox2 is also deleted. The passwords are stored in two settings: what, and pw. The items that will be deleted will have the same value. By value i mean they will be the same number item. E.G. the 1st item, or the 3rd item in the list.

I'm a student and I have a small project to create for my VB class. For the personal touch, I tried using a ListView to manage a SQL database (on a remote web server).What I need to do right now is determine how many items are selected (if more than one, enable delete and edit buttons, if more than one, disable edit button). I searched a lot for that, but didn't find anything working with me.Do you know a simple way I could get the number of items that are selected in my ListView?

Visual Studio 2005. Is there a way to determine which menu item is hi-lited in a ContextMenuStrip?
For example: I associate ContextMenuStrip1 with TextBox1.ContextMenuStrip1 contains 5 items with names:
Item1ToolStripMenuItem
Item2ToolStripMenuItem
Item3ToolStripMenuItem
Item4ToolStripMenuItem
Item5ToolStripMenuItem
A sub-menu is created with Item3ToolStripMenuItem that contains 5 items with names:
Item3aToolStripMenuItem
Item3bToolStripMenuItem
Item3cToolStripMenuItem
Item3dToolStripMenuItem
Item3eToolStripMenuItem
As the menu is navigated is there a way for the program to know which of the 10 menu items is hi-lited before a click event occurs?

I am using a webbrowser control, which is used for both internet and folder exploring. How can I determine when viewing files on the local directory, which file is selected?
I ran across something in my searches saying there was a property under the webbrowser.document called SelectedItem. But this must not be in 2008.

For some reason, before the selectedindexchanged sub routine finishes, combobox Description is still pointing on the last selectedindex changed and the combobox Image is on the actual current selected index changed. Once it exits the routine both combobox are in the current value.
I cant see why this is happening, causing a lot of trouble.
