I am trying to use HDI membership provider and this is my Users table structure:
And in my recent question asked here Oded helped me out trying to figure the problem with my Insert statement and I re-modified it and I have an ApplicationName column in my database structure I need to specify it.(As it should not be null value)
Now I need to add my application name by default to enter to database as we do it for web.config.
This is what I mean.
I need to add that MyApplication to my app.config file.
So How do I do that?
This is how I'm trying to enter user details to database but it is not enetering a single value
Try
Dim connectionString As String = "Data Source=.\sqlexpress;Initial Catalog=HDIMembershipProvider;Integrated Security=True"
Using cn As New SqlConnection(connectionString)
cn.Open()
Dim cmd As New SqlCommand()
cmd.CommandText = "INSERT INTO Users ( Username, Password, Email, PasswordQuestion, PasswordAnswer) VALUES(#Username,#Password,#Email,#PasswordQuestion,#PasswordAnswer)"
Dim param1 As New SqlParameter()
param1.ParameterName = "#Username"
param1.Value = txtUsername.Text.Trim()
cmd.Parameters.Add(param1)
Dim param2 As New SqlParameter()
param2.ParameterName = "#Password"
param2.Value = txtPassword.Text.Trim()
cmd.Parameters.Add(param2)
Dim param3 As New SqlParameter()
param3.ParameterName = "#Email"
param3.Value = txtEmail.Text.Trim()
cmd.Parameters.Add(param3)
Dim param4 As New SqlParameter()
param4.ParameterName = "#PasswordQuestion"
param4.Value = txtSecurityQuestion.Text.Trim()
cmd.Parameters.Add(param4)
Dim param5 As New SqlParameter()
param5.ParameterName = "#PasswordAnswer"
param5.Value = txtSecurityAnswer.Text.Trim()
cmd.Parameters.Add(param5)
cmd.Connection = cn
cmd.ExecuteNonQuery()
cn.Close()
End Using
Successlbl.show
Successlbl.show.Text = "Regisration Success."
Catch
Errolbl.Show()
Errolbl.Text = "Your account was not created.Please try again."
End Try
Can anyone point me out where I'm making mistake.
And this is the final result I'm getting while entering to database:
To be more short and clear I need to enter the above shown User details to my database using the HDI membership provider.

Answer 1

There is a better way by using the following steps:
1) Add a reference to System.Configuration to your application.
2) Add the following block to your app.config file, within the configuration section:
<appSettings>
<add key="ApplicationName" value="/MyApplication" />
</appSettings>
3) Retrieve the value and use it where needed with the following code (example from your answer shown):
param6.Value = System.Configuration.ConfigurationManager.AppSettings("ApplicationName")

Answer 2

Add a AppSettings section to your web.config
<appSettings>
<add key="ApplicationName" value="/website1" />
</appSettings>

Answer 3

I have figured out the problem Myself after a lot of hair pulling and found the solution that I have changed my code in this way:
cmd.CommandText = "INSERT INTO Users ( Username,ApplicationName,Password,
Email, PasswordQuestion, PasswordAnswer) VALUES(#Username,#ApplicationName,#Password,
#Email,#PasswordQuestion,#PasswordAnswer)"
And add another Param this way:
Dim param6 As New SqlParameter()
param6.ParameterName = "#ApplicationName"
param6.Value = txtApplicationName.Text.Trim()
cmd.Parameters.Add(param6)
I know this not the best way If anyone found any other best solution let me know.
