VB doesn't seem to let you ReDim Preserve UDT arrays with an Lbound less than that of the original- while you can change the Ubound fine with this method, changing the Lbound always produces a subscript out of range error for me.
Is this the case, or am I wrong?
Thanks

Seems illogical to change the lower bound of an array?
MSDN redim MSDN lbound
HTH

Yeah but if Microsoft are providing a ridiculously easy array system for VB, they should finish it rather than getting bored with the complexity halfway through!
Anyway, I've found a solution - I just use one array for the positive indexes, and the other for negative indexes (inverted). Then I don't need to change the lower bounds, only the upper of each array.
