VB GridView control will not allow code in the vb code file to access a data column that has its visible property set to false. When it is set to true, the data column can be accessed with no problem. Any suggestions as to how to correct this? I have looked through the documentation, text books, and I have not found anything that gave me any clue as to what the problem could be. I thought that the property was just applied to the column, not that it would remove the column from being accessible.

I am currently writing a bit of software for myself and need guidance.
I have a datagridview on a form with a date column. (column0)
I am trying to sort this by date desending but it will only sort by the day (dd) and not the whole date (dd/mm/yyyy) which leaves the months unsorted.
(example of output):
#1 - 01/03/2012

#3 - 03/02/2011

I have now started posting to a MySQL database created by someone else. I have no ability to change the table structure.Two questions:
1) There is a date field and a time field that loosely tracks the last edit date and time. Both are fields set up as DateTime in the database. The date field always has the proper date but the date and time portion shows as
2011-11-27 00:00:00
However, the time field shows as
1899-12-30 23:16:58.
When I am updating with the following code
strSQLCmd.Parameters.AddWithValue("@EditDate", Date.Now)
strSQLCmd.Parameters.AddWithValue("@EditTime", TimeOfDay)
The date field displays
2011-11-27 23:40:26
and the time field displays
0001-01-01 23:40:26
I'm not sure how to format the date field without time and the time field with Dec 30 1899.Question 2) I will be adding some tables and will be wanting to track date and time of first entry as well as date and time of last edit. (this may have been better posted in the Database forum, if so, sorry)
For those of you who have done this before, would you mind sharing best practises? I am wondering why would you use two fields, one for date and one for time, when the field is a date/time field to begin with. I've seen this before in another database as well. I'm just trying to work out the logic here.
Ours is a transportation company. We do services/transportation/logistics for various companies.I am working on Scheduling a work order process for those companies who are registered with us.While during the process of registration, a company will specify the week number to execute a job during the contract period.So this will be a routine service which we need to perform for every number of weeks specified For Example: if any company specifies the week number as : 2. that means for every 2 weeks we need to do the service for that company during the contract period.
How to update the dates into the database server for each company for their jobs to be performed.So if my Admin wants to know all the jobs in this current week. I should be able to pick only those companies and their jobs in this week only.
