VB.NET/MS ACCESS Saving today's date produces 2020-02-25 08:28:00.946341400

At the risk of repeating myself again and again: use the Value. That way the date can be formatted for display into any culture.
Heaven forbid you repeat yourself or provide a code example.... dickhead. It may be wrong but it works the way I want so until I see an example I am going to keep it this way and move on. I will worry about figuring out what exactly you are talking about later.

The explanation is spot on, but to expand with code;
dim someDateString as String = dtPick5.Value.ToString(..
This creates a text, with the date formatted in some culture.
dim someDate as DateTime = dtPick5.Value
Here the value is taken as is, without formatting. It is stored as a decimal value, with "days" in the integer part from a given offset, and the decimal part representing time. It is a format-independant version, and that's how it should be stored. Internally, your application should use DateTime values, and only formatting them as strings when displaying. Saving the value in DateTime type is important; if you use a localized and formatted version tht is actually a string, the computer will have to convert that to a real DateTime for each operation.

When I save the attendance date from a datetimepicker as a date prior to today's date it records acceptable format but not what I really want. When I select today's date it records a date like this 2020-02-25 08:28:00.946341400. The secondary issue is what I eluded to above. I set the custom format in the form_load to "MM, dd, yyyy" and when I select a date prior to today's date it records the date like this 2020-01-29 08:34:25. Here is the Save Button code
Dim inserted As Integer = 0
For Each row As DataGridViewRow In dgvAttend.Rows
Dim isSelected As Boolean = Convert.ToBoolean(row.Cells("chkbox").Value)
If isSelected Then
Access.AddParam("@DTE", dtPick5.Value)
Access.AddParam("@SID", row.Cells("StudentID").Value)
Access.AddParam("@LN", row.Cells("LastName").Value)
Access.AddParam("@FN", row.Cells("FirstName").Value)Access.ExecQuery("INSERT INTO Attend (TrainDate,StudentID,LastName,FirstName) " & "VALUES (@DTE,@SID,@LN,@FN); ") inserted = inserted + 1 End If Next If inserted > 0 Then MessageBox.Show(String.Format("{0} records inserted.", inserted), "ACJTracker", MessageBoxButtons.OK, MessageBoxIcon.Information) End IfHere is the form load
dtPick5.Format = DateTimePickerFormat.Custom
dtPick5.CustomFormat = "MM, dd, yyyy"
RefreshAttendGrid()Here is the refresh Grid
dtPick5.Format = DateTimePickerFormat.Custom
dtPick5.CustomFormat = "MM, dd, yyyy"' RUN QUERY Access.ExecQuery("SELECT StudentData.StudentID, StudentData.LastName, StudentData.FirstName FROM StudentData ORDER BY StudentID ASC") ' REPORT & ABORT ON ERRORS If NoErrors(True) = False Then Exit Sub dgvAttend.DataSource = Access.DBDTDoes anyone know how I correct these issues?
Weird since examples seem to work with a single comma. You could try to escape extra characters (i.e., commas):
dtPick5.CustomFormat = "MM',' dd',' yyyy"
or keep using a more common form.

Ah yes, the lazy person's fallback position when you don't get someone else to do your work: abuse.

I think the issue you may be facing is that you are storing the data as datetime which naturally includes the time component. If you do not need the time component then you should store it as a date data type (not sure if Access has such a data type). If the is a requirement for the time component then you need to format every instance of the data as it is presented and you need to cater for the time component in all your queries ie you can no longer query for a date you will need to query for the range of datetime records between midnight and midnight the date after.

Good for me I never did that :rolleyes: It is one of umpteen coders frustrated at how dates don't work like they imagine. Not something unique nor new.
