Sqlite Getting Date From Datetime That Was Saved As Dbtype.string
Apr 4, 2012
When I looked at the database record, the datetime saves like this: 4/6/2012 04:42:28 PM
because I've save it using dbtype.string
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)
To populate my database I have been using the builtin SQLite command for datetime:INSERT INTO samples (timestamp, sample_value) Values(datetime('now','localtime'), ...)When I look at this on my Mac using a SQLite Reader called Base I see the following timestring:
I have some some dates as strings in the format dd/mm/yyyy which I need to convert to DateTime object.uggest a simple routine which I can use inside a Loop which produce these Strings.
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: System.ArgumentOutOfRangeException was unhandled Message="Index and length must refer to a location within the string. Parameter name: length" ParamName="length"
I am importing a .txt file to a gatagridview and writing out a Schema.ini fileMy columns that contains a date value is empty in my DGV when i use the:DateTime in my .ini fileIf I set it to Char then my date is populatedDoes this mean my dates in the text file are not really dates but strings ??
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 :
i use ar-SA culture in my app and the date appeared correctly then i save this date to db and i look at the db i found it in English format how to save in the format like it was appeared in my form ?
the last date was saved on database is: 6/13/2012 12:27:30 PM
In my DateTime Now is:6/13/2012 01:27:57 AM
but, when I execute this function, it always say:"Date has been manually modified, Please Set to Valid DateTime" But, DateTime Now is NOT lessthan the Date from my Database. What's wrong?
I'm pulling into a variable a datetime value. Now, I want to post this value back to my database, but I need it to be only the year digits. How do I get VB.NET to trim the month, day, and time off and just return the four character year (e.g. 2011)?
