string arrays

[vishalgupta]

i have a string and want to split it at the spaces so i used the following code from the microsoft site:

Dim TestString As String = "apple    pear banana  "
Dim TestArray() As String = Split(TestString)
' TestArray holds {"apple", "", "", "", "pear", "banana", "", ""}
Dim LastNonEmpty As Integer = -1
For i As Integer = 0 To TestArray.Length - 1
    If TestArray(i) <> "" Then
        LastNonEmpty += 1
        TestArray(LastNonEmpty) = TestArray(i)
    End If
Next
ReDim Preserve TestArray(LastNonEmpty)
' TestArray now holds {"apple", "pear", "banana"}

i m using visual basic 6.0. the variables cudnt be initialized where they were difined so i manipulated the code as

Dim TestString As String
TestString = "apple    pear banana  "
Dim TestArray() As String
TestArray() = Split(TestString)
' TestArray holds {"apple", "", "", "", "pear", "banana", "", ""}
Dim LastNonEmpty As Integer
Dim i As Integer
LastNonEmpty = -1
For i = 0 To TestArray.Length - 1               'THE ERROR LINE
    If TestArray(i) <> "" Then
        LastNonEmpty = LastNonEmpty + 1
        TestArray(LastNonEmpty) = TestArray(i)
        MsgBox TestArray(LastNonEmpty)
    End If
Next
ReDim Preserve TestArray(LastNonEmpty)
' TestArray now holds {"apple", "pear", "banana"}

y does this happen?? and it still shows invalid wualifier for TestArray.Lengt h..is there any other way to find the length so dat we cud run the loop ftill dat value only???? i did try len(TestArray) and GetLength(TestA rray) but to no avail

maybe that code is only for VB.net
because i try to run the code (from microsoft), with a bit changes by add a listbox (ListBox1) into the form:

Dim TestString As String = "apple pear banana "
Dim TestArray() As String = Split(TestStrin g)
' TestArray holds {"apple", "", "", "", "pear", "banana", "", ""}
Dim LastNonEmpty As Integer = -1
For i As Integer = 0 To TestArray.Lengt h - 1
If TestArray(i) <> "" Then
LastNonEmpty += 1
TestArray(LastN onEmpty) = TestArray(i)
ListBox1.items. add(TestArray(i ))
End If
Next
ReDim Preserve TestArray(LastN onEmpty)
' TestArray now holds {"apple", "pear", "banana"}

it works

it is not working . i am working in vb 6.0 and i havent done vb.net so i cant comment on dat. the code is having same errors:
1) it shows TestArray as invalid qualifier
2)the variables cannot be iinitialized where they r defined

In VB6, an array doesn't have attributes like .Length - that's from other languages (like Java, or its close cousin, VB.Net). What you need to use is the Ubound() function.

thnks a lot ...can u tell me any place or link where we can search funtions by the job they do and not by their names???lest i wud have found ubound() myself

I think the MSDN website has some such reference, but it might take a while to track down the right place to browse. There's a lot of information there.

Also, I've just tried a Google search on "vb functions by category" and there were a few hits that looked as though they might be relevant. I didn't take the time to look at more than one or two, though.

Perhaps we could start such a list here, in our Articles section. (And we could add info on how to achieve similar things in VB and VB.Net)

Keep in mind, a bit of creative searching will often find what you want. For example, if you were to search TheScripts for something like "VB ARRAY SIZE" you would probably find some relevant entries, but you may need to spend some time reading through the discussions.
