[RESOLVED] [02/03] Simple combobox question

Hi people,

I was hoping someone could help me out please, the question is really simple.

I have 2 forms, on form 1 I have 2 buttons which both open up form 2. What I want is when button 1 opens up form2, I want to display text 1,3 and 4. And when button 2 opens up form 2 I want to display only text 2 in the combobox.

In the combobox collection I have the following text one, two, three, four.

So far I have the following coding which doesn't do much apart from display two in the combobox when button 2 is selected:

Code:

---


'button1
 frm2.ShowDialog()
 frm2.Dispose()

'button2
 frm2.Tag = "Two"
 frm2.ShowDialog()
 frm2.Dispose()


frm2 load event'

  If Me.Tag = "Two" Then
            cmbnum.SelectedIndex = 1
            cmbnum.Text = "Two"

---

Any help please? thanks

Remove all the text from the combobox, so the list is empty.

Then, if Tag = "Two"
cmbnum.Items.Add("Two")

Oh, sorry how would I empty the list in the combobox?

vb Code:

Me.ComboBox1.Items.Clear()

Oh ok, So far I deleted the items in the cmbnum collection (one, two, three, four as the text is going to be hard coded.) Then I have the following coding on the form2 load event:

Code:

---

        Me.cmbnum.Items.Clear()
        If Me.Tag = "Two" Then
            cmbnum.Text = "Two"
            If cmbnum.Items.Count > -1 Then cmbnum.SelectedIndex = 0
        Else
            Me.cmbnum.Items.Add("One")
            Me.cmbnum.Items.Add("Three")
            Me.cmbnum.Items.Add("Four")
            If cmbnum.Items.Count > -1 Then cmbstatus.SelectedIndex = 0
        End If

---

Now when button one opens up form 2 it shows the correct data in the combobox, however when button two opens up form 2 it breaks on the following line:

cmbnum.SelectedIndex = 0

Additional information: Specified argument was out of the range of valid values.

Any help please?

You did not add "Two" to the combox when button 2 is clicked. Setting the text does not add to the list of items.

Code:

---

        Me.cmbnum.Items.Clear()
        If Me.Tag = "Two" Then
            cmbnum.Text = "Two"
            Me.cmbnum.Items.Add("Two")
            If cmbnum.Items.Count > -1 Then cmbnum.SelectedIndex = 0
        Else
            Me.cmbnum.Items.Add("One")
            Me.cmbnum.Items.Add("Three")
            Me.cmbnum.Items.Add("Four")
            If cmbnum.Items.Count > -1 Then cmbstatus.SelectedIndex = 0
        End If

---

Also, your If cmbnum.Items.Count > -1 doesn't check for empty list, in which case the count would be 0.

thanks
