I realize the code listed below, whose serial port using string formatting which I inherited is complicated. It formats a Date obtained from a DatePicker control into a "yyyy-MM-dd HH:mm:ss" string format to send to a hardware device to be stored via Serial Port retrieves the date from the device and displays to user What I'm trying to do is port the code for use in a Socket rather than Serial Port which wants a Byte Arrray of the same Date Time string variable. I can't figure out how to encode and convert to Bytes the string value used in the Serial Port version. The evolution of the process is listed from top to bottom.

I'm returning a database query into a List object and using that list object to fill the X and Y axes of my chart as seen below. (_runData is a "List(of DatabaseTableName)" style Object filled with the results of my query.
Primary_Chart.Series(0).Points.DataBindXY(_runData, "DateTime", _runData, "UPPER_PRESSURE")
My Datetime field is returning as a Serial Number (i.e. 40116.76111) so I want to format the X Axis to display the field more readably. Enter my problem code.

All of my regional settings in control panel are set to UK but when I retrieve a date from an SQL database (run from my PC) in my program, it appears in the MM-DD-YYYY format rather than the DD-MM-YYYY format that I expect.
After a bit of troubleshooting I found that this is because of the fact that SQL server always stores its dates in that format - so then when my program reads the data from the database it interprets it as being the US format.How can I convert this to UK format bearing in mind I am working with Date objects not strings?

I have a function that is getting passed a String and a DataRow.The String is a custom formatter. The idea is to do this
String.Format(passed_in_String, DataRow("ColumnINeed"))
The reason this is being done is at this point we have no idea what the column contains.However, if the formatter is "{0:MM/dd/yyyy}" and the DataRow("ColumnINeed") is an integer containing 42, String.Format is returning: MM/dd/yyyy In this situation I need it to throw an exception instead of returning nonsense.Is there anyway to make String.Format throw an exception if the object does not match what the format string is expecting?
example: inside regional date format setting i set "Short date format dd/MMM/yyyy" and inside vb.net program i set "strSQL = strSQL & ",'" & Date(Date.Now.ToString("dd/MM/yyyy")) & "'" ----> working fine. if user changed the regional date format setting to other format like "mm/dd/yy" facing problem during saving record into sql table. error date conversion. It's possible to avoid using computer regional date format from vb.net? or have any other way...
