Tariq Ahma #3 / 5	ReDim in MyArray this is what i use: try i = ubound(myarray) catch i=0 end try Quote: > It's the same.. > it's no correct... have you another solution ?? > > Please try: > > UBound(MyArray) > > or > > MyArray.GetUpperBound > > HTH > > > I have this problem > > > I had declared an Array that i want to encrise.... > > > this is the code > > > Dim MyArray() As Double > > > If MyArray.GetLowerBound(0)=0 Then > > > ReDim Preserve MyArray(5) > > > Endif > > > where i process > > > If MyArray.GetLowerBound(0)=0 Then > > > i found an error .. how i can test when my array have no elements ?? > > > Thanks

You only declared an array variable but never assigned a new object. To test if you've already assigned an array to MyArray: If MyArray Is Nothing If it is not Nothing, you can use MyArray.Getupperbound(0). To create a new array, use Redim. If there are startup values for the array, you can also use MyArray = new Double() {1, 2, 3} Armin

Edward #5 / 5	ReDim in MyArray Please try: UBound(MyArray) or MyArray.GetUpperBound HTH Quote: > I have this problem > I had declared an Array that i want to encrise.... > this is the code > Dim MyArray() As Double > If MyArray.GetLowerBound(0)=0 Then > ReDim Preserve MyArray(5) > Endif > where i process > If MyArray.GetLowerBound(0)=0 Then > i found an error .. how i can test when my array have no elements ?? > Thanks
