DateTime Comparison in SQL and VB.NET

Hi,

I am trying to compare two dates which I believe are in long datetime format although I receive the following error -

The conversion of a char data type to a datetime data type resulted in an out-of-range datetime value.

Code in VB -

Select * FROM Project WHERE (ProjectDate <= '" & Trim(DateTimePicker1.Value) & "')"

Pass the date in odbc format YYYY-MM-DD or YYYYMMDD

What datetime format do you get when you do this in your VB application (see code snippet)?
If the format is not what your SQL server is expecting, then you may get the issue you are seeing.  For example if your application is generating dd/MM/yyyy and SQL is expecting MM/dd/yyyy then a date such as this would be invalid: 13/07/2009.
MsgBox(DateTimePicker1.Value)

why don't you try something like this?

Select * FROM Project WHERE (ProjectDate <= convert(varchar(20),'" & Trim(DateTimePicker1.Value) & "',120)

Exactly, as Aneesh indicated.  I was going to suggest you converting the format accordingly, but Aneesh has already posted a good suggestion regarding that.  To implement, just use the ToString of date and pass in the format string corresponding to the ODBC format shown.
Select * FROM Project WHERE (ProjectDate <= '" & DateTimePicker1.Value.ToString("yyyy-MM-dd HH:mm:ss") & "')"
