I am trying to insert an array into SQL with no luck. I get the string from a GPRS device that looks like this:
/WeightBridge.aspx?ReadeID=A1B5A0F5C4E4A1B5A0F5C4E4&TagID=45B6C56A90B645B6C56A90B6,A47B1256A45F0843,B49B1256A45F08FF,30 SEP 2010 21:33:59,I,&Custom=Vehicle Num
All I want to do is to split the TagID array and insert it with the rest of the string into a SQL table. The TagID array must inserted into the following colomns in the DB. TagID, TID, UserMemory, DateTime and Direction. After the insert I just give a response that the insert was successfull or failed. Thank you

I am trying to insert data from a booking reservation into my database.
MySQL = "Insert into [RestaurantSteakHouse].[dbo].[reservation]([customerid],[reservationdate],[noofguests],[notes],[tableid]) values (" & id & ",'" + Session("ReservationDate") + "'," & Session("Noofguests") & ",'" + Session("Notes") + "','" + Session("TableId")

I have a FormView that allows a user to register for a company event. I want to do a couple of things with this form.
1. I need to write this data to a MS SQL database
2. I need to send an email confirmation of their registration to their email.
I know how to do both of these things, but i am having trouble doing both at the same time.
It would be nice if I could do it in one click, but I coded it into two pages to try to help simplify it.
The first page allows the user to input their information into a formview and when they click the submit button, it places those answers into session variables:
[Code]....
[Code]....
The Second page confirms the users information by taking those session variables and placing them into labels:
[Code]....
[Code]....
However, after I place information into the formview on the first page, it throws up this error:
"Conversion from type 'TextBox' to type 'String' is not valid".
I have this error "The given value of type String from the data source cannot be converted to type datetime of the specified target column." when I used sqlbulkcopy to do the transaction

I need to pass many records with number of fields(i.e 5rows and 5 columns) in either array or table form to oracle for processing. Is it possible to pass array/table from asp.net pages? If no, any solutions for this? I have been thinking of passing it as string concatenated with delimiter and split it. Seems like it is not appropriate as i have to pass 5 strings(5rows)

View 1 RepliesI have a gridview where I can browse an user's information. Through the gridview I'm also able to edit some of this information. A recent change in my client's needs demands that one of these fields is now a DropDownList. This field represents a user's "schedule" (not literally a schedule but works like one), and the different schedule options to be assigned to a user are shown in the drop down list.
Problem: In the drop down list I want to show list items like "9-12 15-17", "10-14 15-18" so that it is easy for the administrator to tell which schedule he's assigning to an user. However, that shouldn't be their actual value. I need "9-12 15-17" to actually be '1' since this is the schedule ID that I'm trying to pass on to the DB.
Here's what I have so far:
[Code]....
And with this last method I change the selected item's value to the Index. Meaning that if I select "9-12 15-17" which has an Index of 1 in the dropDownList, the actual value is now 1. Again, this is the behavior I expect. My experience with ASP is quite little as I'm new on this, but as far as I know, this only actually updates the string array. How would I go about modifying this to reflect my updates on the database? All input is taken into account.
I would like to split the string to the string array.
but when the string hasn't has the splite sperator, i can't put the string into string array directly.
how to do?
if (Str.Contains(','))
{
str_array=Str.Split(',');
}
else
{
str_array=Str; <-- error occurs at this line.
}
