When I looked at the database record, the datetime saves like this: 4/6/2012 04:42:28 PM

Now, I'm getting the date only, not including time, this is my code:
Private Sub getpapererror(ByVal ddate As String)
Dim sqlstr As String = "select * from perror where date(ddate) = $xddate"
Dim sqlcmd As New SQLiteCommand(sqlstr, mycon)

I having a problem converting a string into the date format I need. An example of the string I'm trying to convert would be 215056081909. I would like to convert that string into 08/19/09 21:50:56.The code listed below is what I'm trying to use for the conversion process. When I run the code I'm getting the error below and I'm pretty sure it's because my string has the time portion in military (24 hour) time.
Error:

I am located in the NorthEast US. My problem is properly storing a string in European date format (today is 23/1/2012).
For example the string '12/1/2012' is stored as as December 1, 2012 not January 12, 2012.
How can I dimension a DateTime variable to store the European date string properly?

View 3 Replieshow I can ensure that conversion of a date to a string and a string to a date will give me the same date format.
For example:
Code:
Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
Dim d As Date = Date.Now
[code].....
I'm actually only interested in the date part as the label text shows so f is more than I want.But also, the day and month are reversed.
My problem is probably ignorance as to how the DGV works, anyway, the problem.I have a bound datagridview which is used to collect user input. Data for 3 of the 7 fields is entered by looping through the rows and progmatically entering common data anfter a 'Save' Button is pressed:
For I = 0 To DG1.RowCount - 2
DG1.Rows(I).Cells(4).Value = TextBox1.Text 'Operator
DG1.Rows(I).Cells(5).Value = TextBox2.Text 'Date
DG1.Rows(I).Cells(6).Value = TextBox3.Text 'Time[code]....
At this point the DGV looks the way it should...All fields completed correctly and no un used ro except for the new row.After saving :
Me.ItemTableTableAdapter.Update(Me.StockMoveDataSet.ItemTable)
The 'Operator', 'Date', and 'Time' are not saved to the database for the first row only
