Hi,
Do you mean doing SELECT @num_of_user instead of SELECT COUNT(*) AS num_of_user?
If it is, I don't think I could not select @num_of_user as it is suppose to capture the return value from the stored procedure and show it back to me.
Sorry if I did not get what you mean.

Hi,
try this way...
SET @num_of_user = SELECT COUNT(*) FROM tb_user
WHERE useremail = @username AND userpassword = @password)
RETURN @num_of_user

Hi Kumar,
I'd tried, but the result is still the same, it returns the same value no matter what I type my username and password are.

CREATE PROCEDURE IsValidLogin<br />
(<br />
@username varchar(15) = NULL,<br />
@password varchar(12) = NULL ,<br />
@num_of_user INT = 0 --This means that it's an input parameter<br />
)<br />
Try
CREATE PROCEDURE IsValidLogin
(
@username varchar(15) = NULL,
@password varchar(12) = NULL ,
@num_of_user INT = 0 OUTPUT
)
--Your SET statement here
--No need for a RETURN statement
(OR)
In your C# code
int retVal;<br />
retVal = myCommand.ExecuteNonQuery();
Remember:
If you want any custom output from your SP, use an OUTPUT parameter. By default an SP returns 0 if it was successful and non-zero in case of failure. This must be used exclusively for error checking.

Hi i_like_tintin,
I tried your way and the retVal keep on returning -1 value. So I tried to display the objParam3.Value which I declare as objParam3.Direction = ParameterDirection.Output; and it return '0' to me no matter my username and password are correct.

Execute your SP in Query Analyzer and check if it works without errors for different sets of input.

Hi,
When we are creating text box at runtime.
We can use the the object the text box.
but here You used same object "txttextbox" so you can
use "FindControl" method and assign it to a textbox and retrieve the
value.
Magh_M wrote: txttextbox.ID = "txtproduct" & strfieldnum
here u are assigning id to text box.U can use this ID inside FindControl.
To succeed, we must first believe that we can.

Hi,
I dont know what control is ir "plhbookfields"
U can use
Dim MyText as TextBox = plhbookfields.FindControl("YourTextboxID")
Now you can access the value by using
MyText.Text
If there are many text box you should make a loop.
"YourTextboxID" is the ID you assigned to text box.
To succeed, we must first believe that we can.

Hi,
Here txttextbox is not the id of text box.
txttextbox.ID = "txtproduct" & strfieldnum
You used the above code in your program to generate id.
So use the same mechanism to get id and fin the control.
To succeed, we must first believe that we can.

Hello all. Can anyone tell me why this works?
I dynamically create a bunch of Dropdownlists, and every time I do I add them by this.Controls.Add(), but I also add them to a Page.List<dropdownlist> that I made. This is all within Page_Load. I was trying to figure out a way to check the SelectedIndex of each list after Postback.
So after postback, all the dropdownlists stored in my List actually contain accurate SelectedIndex values. How can this be? My List only contains copies of my dropdownlist objects right? And I built the List before their view states should have been updated. Am I missing something?
So basically this works like I wanted, but I don't know why 
Thanks!

What is stored in your list is a pointer so it is not a copy but the actual object. So when the object is updated on the post back your pointer is pointed to the updated object.
To store a copy you would have to clone the dropdown and store the pointer to that.

Wow really? I'm confused then. What about this:
List<string> dinosaurs = new List<string>();
dinosaurs.Add("Tyrannosaurus")
Err, my point being that the list can't store a pointer to "Tyrannosaurus".
Thanks

There are some items that are stored directly by value. That would be the common types like Strings, int, etc. Any object will always be stored by reference which is a pointer.
