Hi Guys,

I am calling a store procedure from asp.net webpage and one of whose parameters are of type datetime and I write the following code to add the sql parameters:

        Dim st As String
        Dim dt as datetime
       
        st = DropDownList17.SelectedValue + "/" + DropDownList10.SelectedValue + "/" + DropDownList5.SelectedValue _
        + " " + DropDownList3.SelectedValue + ":" + DropDownList4.SelectedValue + ":00"

        dt = DateTime.Parse(st)

 Dim p3 As New SqlParameter("@dateto", SqlDbType.DateTime, dt)

And I get an error value of type DATE CANNOT BE CONVERTED TO INTEGER.

Any help much appreciated.

The store procedure is as follows:


CREATE procedure spcheckbookings
@categoryid as integer,
@equipmentid as integer,
@dateto as datetime,
@dateend as datetime
as

Select count(*) as Counter
from tbBookings
where
CategoryId = @CategoryId
and
EquipmentId = @EquipmentId
and
(
       (dateto >= @dateto    AND @dateto    <= dateend) -- requested period starts inside of an existing period
        OR (dateto >= @dateend AND @dateend <= dateend) -- requested period ends inside of an existing period
        OR (dateto <= @dateto    AND @dateend <= dateend) -- requested period falls completely inside an existing period
        OR (dateto >= @dateto    AND @dateend >= dateend) -- requested perod completely overlaps an existing periodf
)

3rd parameter of Dim p3 As New SqlParameter("@dateto", SqlDbType.DateTime, dt)
is size of the parameter type. But u gave it as value of the parameter.
try like this
 Dim p3 As New System.Data.SqlClient.SqlParameter("@dateto", SqlDbType.DateTime, 4)
        p3.Value = dt

Hi.


I m still struct on error of "STRING CANNOT BE CONVERTED TO DATETIME"

The value of String i m tryin to convert looks like:
st = 5-29-2006 12:00:00

I can't think whats wrong with the above value..

and then write
dt = Datetime.Parse(st)

Do I need to import any class to achieve this?

cheers

pass the values to DateTime Constructor
 Dim dt As New DateTime(2003, 7, 31, 10, 30, 0)
