Did you check the query that was generated by SqlCommand object?

Change following query

VB

Dim cmd1 As New SqlCommand("insert into users1(user_no,username,password,email,institname,institlisn,lisn_path,stutus,mobile,city,area,town,cord_x,cord_y,map_name,map_path)values(@user_no,@username,@password,@email,@institname,@institlisn,@lisn_path,@stutus,@mobile,@city,@area,@town,@cord_x,@cord_y,@map_name,@map_path)", conn)

to below query

VB

Dim cmd1 As New SqlCommand("select user_no,username,password,email,institname,institlisn,lisn_path,stutus,mobile,city,area,town,cord_x,cord_y,map_name,map_path from users1", conn)

Solution 1

Replace these lines

VB

Session("user_no") = Val(TextBox1.Text)
cmd1.Parameters.Clear()
cmd1.Parameters.AddWithValue("@user_no", Session("user_no"))

with this one

VB

Session("user_no") = TextBox1.Text;
cmd1.Parameters.Clear()
cmd1.Parameters.AddWithValue("@user_no", TextBox1.Text)

Make sure that TextBox1.Text has value.

the same problem

Must declare the scalar variable "@user_no".

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.Data.SqlClient.SqlException: Must declare the scalar variable "@user_no".

Source Error:

Line 71: Dim da As New SqlDataAdapter(cmd1)
Line 72: Dim ds As New DataSet()
Line 73: da.Fill(ds, "orders")
Line 74: TextBox1.Text = ds.Tables("orders").Rows(i).Item(0).ToString
Line 75: TextBox2.Text = ds.Tables("orders").Rows(i).Item(1).ToString

Thanks7872 30-Jul-13 1:55am

It simply mean that TextBox1.Text doesnt have any value. Put a breakpoint at the line

TextBox1.Text = ds.Tables("orders").Rows(i).Item(0).ToString

and see what happens.

the same problem rohan leuva but the problem statement now is no row postion in 0

Thanks7872 31-Jul-13 0:07am

It means that you are not getting any data. The problem is with
ds.Tables("orders").Rows(i).Item(0).ToString();

Rectify it and the problem will get solved.
