how to redeclare an array with different size but keep the previous data?

Hi,

Anyone know how to redeclare an array with different size but keep the
previous data? Just like the redim preserve in VB.


Thanks.

Just create a new array and copy the contents of the old array to it. I
believe thats basically all that ReDim does anyway.

Hi Dan,

If the redim is needed in a while loop, how should I do it?

Thanks

In exactly the same way. However, you can make things faster by only
reallocating size in chunks - for instance, doubling the size of array
each time, and then reallocating it once after the loop to the "right"
size.
