Read An Excel File - Loop Through Cells To Get Values?
Jul 25, 2008I'm using VB.Net's Excel component to read Excel file, but the performance is totally slow, since it has to loop through cells to get values. Reading a file containing one sheet with 1162 rows and 105 columns (which is small size compared to my general requirement) already costs more than 5 minutes.1. I want to ask if any of you have suggestion on reading such an Excel file with better performance, except OleDB, cuz most compies here have vesion problem?2. Is it normal that it tooks a long time for Excel component to read Excel file, or is it that I implement the code in a wrong way?

Comparing Two Cells In A Datagridview?
Apr 29, 2010I'm current in college and working on some computing coursework and putting the finishing touches on it when i stumbled across a bit of a problem.I'm trying to compare two cells in a database and i use datagridview to display the database in my form. The database is created by sql commands within my actual program if that makes any difference. What i have created for my coursework is a program that manages the stock and such for a small music shop and in the stock table im trying to compare values in two different collumns, but in the same rows. I need it to display a message box in the event that the value in the one cell is less than the other, which is basically checking if the stock for a certain CD has fallen below the reorder level.
