Question

How to format a DateTime string - VB.Net 2005

Asked by: JMO9966

I'm using a sql select in VB 2005 to retrieve a DateTime field from a SQL Database.

The value comes back like this in Query Analyzer:

2007-02-21 20:24:40.983

Is there a compatible data type in VB to hold this value in this format?

My program updates a table that has this last_updated column.  I need to also update a related table with the same value dwon to the millisecond.

I can't get my VB select command to retrieve this in the same format, it populates in my string or datatime variables like this:

"2/21/2007 9:48:56 PM"

I tried using a string to hold this value and then this command:

LastUpdated = LastUpdated.ToString("yyyy-MM-dd HH:mm:ss")

I get this error though - "Unable to cast object of type 'System.String' to type 'System.IFormatProvider'."

Please help.

Thanks,
JMO9966
