In my last project I had to implement transparent access (via ADO) to huge dataset that had more than 2,700,000 rows (it is displayed on the image above). This table was located on MS SQL Server 6.5 and had size 1.9 GB. I was attempting to use virtual CListCtrl, dynamic cursors, static cursors, multithreading, etc, etc. Really nothing could help me. Response time was endless, or server was hung up because of too heavy loading.
Scrolling through dataset is implemented by scrollbar's substitution - "iterator bar". Really it is right-aligned vertical toolbar with six buttons. Rejection of scrollbar caused by the features of the sequential dataset access.
Of course, for normal response time your dataset (table) MUST be indexed (see documentation).If you will need to solve similar problems then pay your attention to this class. Maybe it really can help you.
All the documentation is located in file TableView.rtf. I was trying to make documentation as clear as possible, but in some topics it is not enough comprehensible. You may have questions after reading about "ORDER BY value", etc. Please look at example on the last page of the documentation. Then you will make all these questions clear as these topics are NOT really complicated, simply I had difficulties when I was describing them. Good luck!
