Re: Passing Dataset to another WinForm

Hi Dan,

On the destination form I created in the constructor a parameter to
accept a dataset instead. Then in constructor I copy dataset to private
dataset variable like so:

private DataSet dsNew;

DstForm(DataSet ds)
{
dsNew = ds.Copy();
}

Wouldn't this work too?

Thanks,

JJ
