I'm trying to use the filter function described here:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/modcore/html/deconusingfilterfunctiontosearchstringarrays.asp

Here's a simple example:

         Dim testArray(2) As String
         Dim testArray2() As String
         testArray(0) = "Hello"
         testArray(1) = "Dude"
         testArray(3) = "Goodbye"
   
        testArray2 = filter(testArray, "o")

But I get this error:
"Wrong number of arguments, or invalid property assignment"

Thanks for the help!

Dim testArray(2) As String

testArray(3) = "Goodbye" << Doesn't this give you an out of bounds error?

Worked perfectly for me in VB6.  It returned "Hello" and "Goodbye".

Option Explicit

Private Sub Command1_Click()
    Dim i As Integer
    Dim testArray(2) As String
    Dim testArray2() As String
   
    testArray(0) = "Hello"
    testArray(1) = "Dude"
    testArray(2) = "Goodbye"
   
    testArray2 = Filter(testArray, "o")
    For i = LBound(testArray2) To UBound(testArray2)
        Debug.Print testArray2(i)
    Next i
End Sub

        testArray(3) = "Goodbye"

should be

         testArray(2) = "Goodbye"

Ok that was a problem, but i'm still getting the error...

hmmm....

shouldn't have awarded the points i guess, maybe yall can help me still...

i have a feeling maybe I need to add a reference to something (i'm working in an old access database)...

I'm using Access 2003, and when I type:
filter(...

it doesn't give me the helpful auto-complete help... perhaps i need a reference for this function or something?

Any ideas?

When in the VBA edit window, press F2.  This brings up the Object Browser.  Do a search for Filter on <all libraries>
I found it in the VBA library as VBA.Strings.Filter()

Hope it helps!

Thanks Erick37!

So this line works:

testArray2 = VBA.Strings.filter(testArray, "o")

My question, Why do I need to type VBA.Strings.filter... does that mean I'm using the wrong VBA reference or something?

I'm still a noob when it comes to how all the pieces fit together... I get the imports statement from VB .NET but I don't understand how all everything gets included into an Access VBA module.

Thanks!!!

I guess another way of phrasing the last question:

In Access 2003, how can I use the VBA.Strings.filter() function without having to type the "VBA.Strings." part?

I'm not sure why this is happening.

Try this:
In Tools->References make sure that Visual Basic For Applications is selected and at the top of the list.

Its is. But I notice a bunch of other non-selected Visual Basic for Applications at the bottom of the list.

The one that is checked at the top of the list is located in:
C:\Program Files\Common Files\Microsoft Shared\VBA\VBA6\VB... something more can't see scrolls off form

Does does this look right? The other non-checked Visual Basic for Applications are dlls and what not in various system32 folders.
