A combobox limited to array

Let's say I have an array called sValid().

I want to make a combobox that the user can only type in string that are inside sValid()
If a user tries to type in a string that is not in the array nothing should happen....

Example:

User tries to type in "testing"
This is possible because the array contains a string "testing"

Now, when the user tries to type in "testings" the result in the combobox text should be "testing"


How do I do this

Try this:

Code:

---

Option Explicit
Private sValid() As String

Private Sub Combo1_KeyPress(KeyAscii As Integer)
    Dim strText As String
    Dim i As Integer
    Dim bIsFound As Boolean
   
    If KeyAscii = 8 Then Exit Sub
    strText = Combo1.Text & Chr(KeyAscii)
    For i = 0 To UBound(sValid)
        If InStr(UCase(sValid(i)), UCase(strText)) Then
            bIsFound = True
        End If
    Next
    If Not bIsFound Then KeyAscii = 0
End Sub

   
Private Sub Form_Load()
    ReDim Preserve sValid(2)
    sValid(0) = "Setting"
    sValid(1) = "Close"
    sValid(2) = "Testing"
    Combo1.Text = ""
End Sub

Set ComboBox style to 2-Dropdown List, and add all array items to comboBox.

Code:

---

Private Sub Form_Load()
    myArr(0) = "Setting"
    myArr(1) = "Close"
    myArr(2) = "Testing"
   
    LoadCombo Combo1, myArr
End Sub

Private Sub LoadCombo(cb As ComboBox, arr As Variant)
Dim i As Integer

    cb.Clear
    For i = 0 To UBound(arr)
      cb.AddItem arr(i)
    Next
End Sub

You could change this style of the combo to "dropdown list" and the user will only be able to select what is in the list. I you really need to let them type stuff in then this should work,
Drop a combo onto a form and paste the following code
Option Explicit
Dim sArray(2) As String

Private Sub Combo1_Change()
Dim i As Integer
Dim sCompare As String
Dim bOk As Boolean

sCompare = Combo1.Text
For i = 0 To UBound(sArray)
If Len(sArray(i)) >= Len(sCompare) Then
If Left(sArray(i), Len(sCompare)) = sCompare Then
bOk = True
Exit For
End If
End If
Next
If Not bOk Then
If Len(Combo1.Text) > 1 Then
Combo1.Text = Left(Combo1.Text, Len(Combo1.Text) - 1)
Else
Combo1.Text = ""
End If
End If
Combo1.SelStart = Len(Combo1.Text)
End Sub

Private Sub Form_Load()
Dim i As Integer

sArray(0) = "one"
sArray(1) = "two"
sArray(2) = "three"
For i = 0 To 2
Combo1.AddItem sArray(i)
Next
End Sub

Thanx Serge,

Works like a charm...

Hey InHumanoid
Altough you have got code from Serge that works for you, you might wanna check out the combobox in the forms2 object library.
It has a property
objekt.MatchEntry [= fmMatchEntry] that checks if what the user types is in the list automatically.
Check out the help for more info :)
