Comparing two list boxes Vb.net

Listbox 1 contains names of hairdressers and Listbox 2 contains services provided by all of them then in Listbox 3 both the selected hairdresser(only 1 allowed) and and selected services are contained. There is a remove button which removes items from Listbox 3. I want a code for the button that if a hairdresser is removed all services also get removed otherwise only services are removed.
For Each str As String In Hairdresser.lstHairdresser.Items
If Not lstHairdresserAndServices.Items.Contains(str) Then
lstHairdresserAndServices.Items.Clear()
Else
'more code here but above statement never gets true
End If
Next
If the hairdresser is always the first item in the 3rd listbox, all you have to do is check if the selectedindex equals 0. If so, clear the listbox. Otherwise just remove the selected item.
Alternatively, you could search the the 1st listbox for the selected string. If found clear the listbox otherwise remove the selected item.
It is also possible to mark the listbox items when you add then to the listbox. Set the tag property to something like "hairdresser" or "service" and when the remove button is clicked all you have to do is check the tag property.
Finally I would recommend a different approach: Instead of adding the items to the listbox, fill a data structure with the hairdresser's name and services, display this structure in the listbox and when the remove button is clicked compare the selected item to the structure to find out what was selected.

How to Make combobox first item style as selected so that typing will overwrite that item

What i wanted is after binding combobox, the first item ( first item will be always header like 'Select Item') need to be in selected style, means the blue back color and typing will overwrite that item (autocomplete starts then).
dropdownstyle is dropdown so that user can type inside combobox.
Wanted like this
When the combobox gets focus the text will be selected automatically.
If you want the combobox to get focus right after the binding you can use
ComboBox1.DataSource = oDataSource
ComboBox1.Focus()
There are two methods :
comboBox1.Focus();
or
comboBox1.select(0, comboBox1.text.Length);

Determine if an item is selected in a listview box

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
Any help would be great! :o)

Ensure that something is selected first by checking that SelectedItems is not empty.
lstMaster.SelectedItems.Count > 0
check lstMaster.SelectedItems(0).Selected
Not sure if I've understood you correctly - Try using the ListView MouseMove event and check that lstMaster.SelectedItems.Count > 0 if you want to change the Enable property of a Button based on whether a row has been selected or not within your ListView control.
Use this checking with "If/EndIf" construction:
ListView1.Items(0).Selected = True

CheckedListBox VB.Net MultiExtended SelectionMode

I have a CheckedListBox with a few items and I want to allow user to select more than one using arrows keys or mouse clicks combined with shift and ctrl keys so I set SelectionMode property to MultiExtended.
In design time it is not possible I get an error:
value property is not valid.
and if I set it in runtime by doing:
clbEmployees.SelectionMode = SelectionMode.MultiSimple
I get an error too:
CheckedListBox is not compatible with multiple selection.
How could I do this?
It's not supported for the CheckedListBox.
However, I'm fairly sure that you could mimic that functionality in a ListView. Just look at the CheckBoxes and MultiSelect properties of the Listview. As far as I can tell from the documenation those are compatible.
This might be too late, but I just put my solution here; Works perfect for me:
1- Just leave the CheckedListBox Selection mode as "ONE' in property sheet.
2- in your code, loop thru the checked item in your checked Box using the checked item property as following:
For each XX as 'DataTpe' in CheckedListBox.CheckedItems
'Here you assign each checked item to wherever you want to direct to'
