Array within an array

[tuchenkwan]

Hello,

I have an array within an array and I want to determine if the entire array is empty or not. For example

Array(0) is Empty
Array(1)(0) has something
Array(1)(1) has something
Array(2) is Empty

How do I loop through the entire array and what condition should I use in my "if statement" to determine if it is empty? Thanks.

If VariableToTestOrArrayElementToTest Is Emtpy Then
 
' or
 
If VariableToTestOrArrayElementToTest = Empty Then

I think one of those works...

An error comes up everytime I try that cause I think the compiler (or whatever) can't traverse the inner arrays with an "if empty" statement. For example:

Using this if statement:

For i = LBound to UBound
if Array(i) = Empty Then
Do something
end if
Next i

The following array will work:

array(0) - Empty
array(1) - Empty
array(2) - Empty

The following array will NOT work:

array(0) - Empty
array(1)(0) - Something
array(1)(1) - Something
array(2) - Empty

An error will occur if array(1)(0) is read into the if statement. Does anyone know how to solve this? Thanks.

Perhaps...a 2 dimensional array?

it's

if isEmpty(VariableToTestOrArrayElementToTest )

but it will not work for array

Actually you cannot have arrays within array in VB. M$ has added this feature in VB.NET though.

Your only workaround is 2 (or more) dimmensional array.

Serge,

I have done this in my application and it seems to work fine. Is there something I have overlooked.

Cheers,
