I am currently working on a project that is giving me some issues. I am using a listbox that has predetermined information in its index items. When I select a item, a second form appears that gives the information about that line. Example:
List Box Selected items = Bob -----> Second form all Labels - Bob, work ID number, Job title and phone number.
the information can not be changed and is part of an array. I have the array set up and everything is ready to go except I can not figure out how to get the information to the second form.
Any help would be greatly appreciated
Try this
Private Sub ListBox1_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ListBox1.SelectedIndexChanged
Dim xFrm As New Form2
xFrm.Label1.Text = ListBox1.SelectedItem
xFrm.Show()
End Sub

Private Sub ComboBox2_SelectedIndexChanged(sender As Object, e As EventArgs) Handles ComboBox2.SelectedIndexChanged
ListView2.Items.Clear()
Dim curSelectionCombobox As String = ComboBox2.SelectedItem.ToString()
ListView2.Items.Add(listitm)
End Sub
Well basically this is what ive come up with the filtering thing in combobox which is obviously wont work
and in the combobox and button i didnt get to try coding those but im quite sure it wont work either im new in this language and im struggling to catch up giving the fact that this pandemic really gets me more and more stupider as the day passed by
Well my main problem is that the filtering in the groupBox_bookShelf is when i choose a genre in the combobox the static listview will filter leaving only the exact items its genre selected in the combobox
the second is the combobox and button im aiming to link the action of both property when filing in the groupBox_bookInformation then once the filter button is clicked i want to filter the lower listview leaving only the selected genre and its items
Here is the sample form ive been working on.
enter image description here
I am guessing that what is selected in the combo box is a value that appears in some of your list view items.
Start by calling .BeginUpdate() This will prevent the user interface from repainting on each update which would really slow things down.
I loop through the items and test one of the sub items to see if it matches the combo selection. If it does not match is is removed.
Be sure to call .EndUpdate or the changes will not show up.
Private Sub ComboBox2_SelectedIndexChanged(sender As Object, e As EventArgs) Handles ComboBox2.SelectedIndexChanged
Dim curSelectionCombobox As String = ComboBox2.SelectedItem.ToString()
ListView2.BeginUpdate()
For Each lvi As ListViewItem In ListView2.Items
If lvi.SubItems(6).Text <> curSelectionCombobox Then
lvi.Remove()
End If
Next
ListView2.EndUpdate()
End Sub
I have a listbox, this listbox contains numbers. (ID's) A timer should check this listbox every mintue, and for every newly added ID, add a webbrowsercontrol to the Form, with 100% width and hight.. So if for example after 5 Minutes I have 3 Items in the listbox, I need to have 3 Webbrowsercontrols one on top of the other. These webbrowsercontrols need to be called in a way that I recognize which one is what. for example: wbcontrol_ID so that I can selectively bring to front the one I currently need. (wbcontrol_ID.BringToFront()) The code also needs to verify that the Webbrowsercontrol has not been generated already, else it will create them over and over again.
This is my code of the timer so far:
Private Sub Timer1_Tick(sender As Object, e As EventArgs) Handles Timer1.Tick
fillitemsinlistbox()
For Each r In ListBox1.Items
dim mybrowser as new webbrowser
Next
End Sub
And here I am stuck.
I have a very simple question that i can't seem to find the answer, i have looked up and down in google, msdn with no luck...
it's really simple yet i can't seem to wrap my mind around it.
here goes:
If i'm using simple Drop down style combo box(the one that looks like a listbox with textbox attached on top of the cbobx control) when i want to update one of the value in it, once i start typing in the textbox the selection inside the combo box is gone. Thus i can't update the value inside the combo box.
i know i can use a regular text box to do this, but i'd really like to make this work or i would really loose sleep over this.
Thanks in advance for all your help.

It doesnt seem very intuative editing the selection in a combobox, but the following should do the trick:
Private cbindex As Integer
Private Sub ComboBox1_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ComboBox1.SelectedIndexChanged
cbindex = ComboBox1.SelectedIndex
End Sub
Private Sub ComboBox1_LostFocus(ByVal sender As Object, ByVal e As System.EventArgs) Handles ComboBox1.LostFocus
ComboBox1.Items(cbindex) = ComboBox1.Text
End Sub
In VB 2008 I created 2 list box. The first list box is to load all the data in my database in a specific row, the other list box is when I double click on the data/item on the first list box the specific data/item need to be transfer to the second list box.
I manage to transfer the data, but the output it gave was wrong. Instead of the actual name of the given data/item the output it gave was System.Data.DataRowView. I tried using .ToString() but nothing happens. I used the drag and drop method for the data adapter connection and the database I'm using is MySQL. I use the "Use data bound items" on list box 1.
You should do it like this,
Private Sub ListBox1_DoubleClick(sender As Object, e As EventArgs) _
Handles ListBox1.DoubleClick
' checks if the item is empty
If ListBox1.SelectedItem.ToString.Length <> 0 Then
' adds on listbox 2
ListBox2.Items.Add(ListBox1.Text)
End If
End Sub
See this,
with simple code you can use this
Private Sub ListBox1_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ListBox1.SelectedIndexChanged
ListBox2.Items.Add(ListBox1.SelectedItem)
End Sub
Good morning all! Myself and a co-worker are tasked with a system-wide scripting solution but neither of us are .NET programmers so we need your help.
We have a GUI that displays a radio selection box (3 options) that are the three sites where our hospitals are. We need to dropdown located on the form to fill with only the locations based on the selected radio option.
my gui http://web6.twitpic.com/img/40330741-85d91a5637f2445b322e62df17cf3351.4aef01c5-full.jpg
Here is the code behind we have so far (sorry, VB)
Public Class frmCEHLI
Private Sub Label1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Label1.Click
End Sub
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
'TODO: This line of code loads data into the 'CELocDataSet.dbo_Locations' table. You can move, or remove it, as needed.
Me.Dbo_LocationsTableAdapter.Fill(Me.CELocDataSet.dbo_Locations)
End Sub
Private Sub btnSubmit_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSubmit.Click
MsgBox("Submit button has been pressed")
End Sub
End Class
For the record the Location dropdown is currently databound but its a static SELECT statement which brings us all the locations but we'd prefer it to be cleaner if it only returned the locations based on Site. We are using Visual Basic 2008 Express Edition for development. Any help/code is appreciated, thanks!
Sorry not to respond back sooner, busy, and wanted to dig up a sample that did just what you were needing.
Create two comboboxes on your form. You can bind either fixed values, or from a table on the first combo. Then, from the property/events sheet, first set the "AutoPostBack" to TRUE, then on the events, click for the "SelectedIndexChanged" event to bring up some code.
The "Sender" object parameter will be the combobox itself, so you'll be able to analyse the property settings via debugging to find what key/value was chosen.
Then, run whatever query from your data querying control, business object, or whatever that gets your results, such as to a DataSet or DataTable.
Finally, set the datasource of your second combo to the above result query, set dataTextField and DataValueField and issue DataBind() to the combo.
That should get exactly what you need.
Then, when someone makes a selection from the second combo, you can have code within ITS "SelectedIndexChanged" event (also based on its AutoPostBack or actual submit button on the form).
Hope this helps.
I would create two combobox controls... One for the "where", then, on the InteractiveChange event by the user to post-back to the page using that answer for the second combobox of locations based on the "where" value of the first combo.
