[visual Basic] How To Confirm A Array Is Null

for example,Dim array() as integerduring run time, how to confirm a array is null (do not contain any element)Thanks

Uh... Are you asking a question or is this like a tutorial? If it is a question, please use the "How do I confirm" or "How is an array confirmed" form, or simply add a question mark. I'm not trying to mock you...

on error goto wDim a() As IntegerDim i As Integeri = UBound(a)    'If a() contains no element an error will occurexit subw:    msgbox "Array is empty!"

Euh... how about this:dim a() as integerif lbound(a) = ubound(a) and lbound(0) = 0 then msgbox "aray is empty"

If the array is completely empty and thus null, you could just use the IsNull function, like so or IsEmpty():If Isnull(array) then msgbox "array is empty"orIf IsEmpty(array) then msgbox "array is empty"

If the array is completely empty and thus null, you could just use the IsNull function, like so or IsEmpty():

If Isnull(array) then msgbox "array is empty"

or

If IsEmpty(array) then msgbox "array is empty"

<{POST_SNAPBACK}>

yes..I just use IsEmpty() function to get the task done.

Didn't really see if you were talking VB 6 or .NET. In .NET you can use the "Nothing" keyword.Dim array() As Integer If array Is Nothing Then 'do something End If
