[RESOLVED] Really simple ComboBox question

Hi all,

I've tried loads of different properties, and search around on Google, but with no luck :(.

How do you select/change an item in a ComboBox?

Say you had a combobox with the values

1
2
3
4
5

How would you make the box display "3" (say, by clicking a button)?

Thanks :D

Arby:

I think you need to give us a little more information such as how you are populating your combobox, where is the informatiion coming from, a database, an array, a CSV file, or ???

If you have any code you have written for this, that might also be helpful.

Ah, it's just a simple one. For example, imagine a form with one combobox "Combo1", a button "Command1":

Code:

---

Private Sub Form_Load()
Combo1.additem(A)
Combo1.additem(B)
End Sub

Private Sub Command1_Click()
Combo1.[Something](1)
End sub

---

Where "[Something]" is the property that I'm looking for.
Basically, the code is for when the form closes, just before Unload (FormName), I want to reset all of the comboboxes to their default values :).

Arby:

Well, I'm still not sure I understand what you need, but you might try this code:

VB Code:

Private Sub Command1_Click()
  Combo1.Text = Combo1.List(Combo1.ListIndex)
End Sub

I'm not sure if that is what you need.???

try this..

VB Code:

Combo1.Text="3"

This may help you.

VB Code:

Option Explicit
 
Private Declare Function SendMessage Lib "user32" Alias "SendMessageA" (ByVal hwnd As Long, _
                                                                        ByVal wMsg As Long, _
                                                                        ByVal wParam As Long, _
                                                                        lParam As Any) _
                                                                        As Long
 
Private Const CB_ERR = (-1)
Private Const CB_FINDSTRING = &H14C
Private Const CB_FINDSTRINGEXACT = &H158
 
Private Sub Command1_Click()
 Dim Strpos As Long
 Strpos = FindItemByString(Combo1, "3", True)
 If Strpos > -1 Then
 Combo1.ListIndex = Strpos
 End If
End Sub
 
Private Function FindItemByString(cmb As ComboBox, ByVal SearchFor As String, Optional FindExact As Boolean = False) As Integer
    FindItemByString = CInt(SendMessage(cmb.hwnd, IIf(FindExact, CB_FINDSTRINGEXACT, CB_FINDSTRING), _
                            CB_ERR, ByVal SearchFor))
End Function

AIS4U,binilmb, unfortunately both of those give me " 'Text' Property is read-only" errors, or just don't work (if a list item is selected)

danasegarane - I think that's way more than I need ^_^;;


I've included a code sample. I'm looking to do something really simple, so you're probably overestimating my needs.

In the sample, I've included all three solutions provided above, and some commenting. Feel free to play around and remove bits ^_^

Try This Code...

VB Code:

For i = 0 To Combo1.ListCount - 1
    If Combo1.List(i) = "ABC" Then Combo1.ListIndex = i
Next

Ah, thanks!
I tested that, and figured out from that code that
Combo1.ListIndex = 0
Was what I was looking for. Thank you!
