hello i'm using visual studio 2008, vb.net and oracle as my db.
this is what i save in my apps.config
<appSettings/>
<add key="SMSDW_connection" value="server=abc;database=efg;User ID=**;Password=**;"/>
and this is my code for calling the apps.config file :
Dim connectionString = System.Configuration.ConfigurationManager.AppSettings("SMSDW_connection")
Dim sqlConnection As OracleClient.OracleConnection = New OracleClient.OracleConnection(connectionString)
but still i got an error which is :
The ConnectionString property has not been initialized.
i have add reference System.Configuration and Imports System.Configuration
The <appSettings> node has the closing tag "/" so the <add is outside of it.
it should read:
<appSettings>
<add ...
</appSettings>

I have written something like this but i am getting error as invalid username.
any suggestions?
You can simply set Connection String in the Web Config file and just reference it based on your requirements.. see below
Web Config:
<connectionStrings>
<add name="SQLDBConnectionString" connectionString="Data Source=<SERVER NAME>;Initial Catalog=<DATABASE NAME>;Integrated Security=True" providerName="System.Data.SqlClient" />
</connectionStrings>
Then to get reference with the connections:
public string SQLServerDBConnstring()
{
return System.Configuration.ConfigurationManager.ConnectionStrings["SQLDBConnectionString"].ToString();
}
I am using IIS 8 and MVC4 Application I am having an error..
Thank You for your Help.
<connectionStrings>
<add name="ClinlabConnectionString1" connectionString="Data Source=.\sql2012;Initial Catalog=Clinlab;Integrated Security=True" providerName="System.Data.SqlClient" />
</connectionStrings>
The connection string in the message error ClinlabEntities is not the same that you posted ClinlabConnectionString1, you should look for ClinlabEntities connection string and add the providerName attribute.
I have installed Microsoft SQL Server 2014 Express, and I am am learning how to use ASP.NET with Visual Studio Express 2015 for Web to retrieve data from a veterinarian database called vetDatabase_Wizard.
As a beginning, I am retrieving a protocolID from an entered ID and storing the information in a class called clinicalCase. I am 100% new to SQL.
Here is my SQLQuery1.sql script (attempt):
Select * from tblCases
CREATE PROCEDURE spGetCaseByID
#ID int
BEGIN
SELECT caseID, protocolID
FROM tblCases
WHERE caseID = #ID
END
Here is my getCaseByID function calling my SQL script:
[WebMethod]
public clinicalCase getCaseByID(int ID)
{
// Retrieve connection string
string cs = ConfigurationManager.ConnectionStrings["vetDatabase_Wizard"].ConnectionString;
using (SqlConnection con = new SqlConnection(cs))
{
SqlCommand cmd = new SqlCommand("spGetCaseByID", con);
cmd.CommandType = CommandType.StoredProcedure;
SqlParameter parameter = new SqlParameter("#ID", ID);
cmd.Parameters.Add(parameter);
clinicalCase cases = new clinicalCase();
con.Open();
SqlDataReader reader = cmd.ExecuteReader();
while (reader.Read())
{
cases.ID = Convert.ToInt32(reader["ID"]);
cases.protocolID = Convert.ToInt32(reader["protocolID"]);
}
return cases;
}
}
When I run the function and try it, I get the following error at
SqlDataReader reader = cmd.ExecuteReader();
Could not find the stored procedure "spGetCaseByID".
I suspect it's my SQL syntax or the fact that I added a connection string in my web.config file because I didn't have one:
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<connectionStrings>
<add name="vetDatabase_Wizard"
connectionString="Data Source=JOHNATHANBO431E\SQLEXPRESS2014;Initial Catalog=vetDatabase_Wizard;Integrated Security=True"

I got the name and connectionString from the properties panel of the database.
I would greatly appreciate the community's feedback because I must be missing something obvious! I would like to thank you very much for your time! :)
EDIT: I realized that I need to first execute my SQL script in SQL Server Management Studio before using it in Visual Studio.
However, I get the following error:
SQL80001: Incorrect syntax: 'CREATE PROCEDURE' must be the only statement in the batch. vetApp
Hence, my SQL script is wrong and would appreciate debugging help.
Your code is trying to run a SQL Server stored procedure called spGetCaseByID.
This stored procedure does not exist in your database.
you are trying to run multiple commands in SQL . In order to create stored procedure it should be the first line of code or place go in between the multiple sql command
Select * from tblCases
GO
CREATE PROCEDURE spGetCaseByID
#ID int
**AS**
BEGIN
SELECT caseID, protocolID
FROM tblCases
WHERE caseID = #ID
END
This will help
I have following app.config. I would like save into ConnectionString key value - my text from serialized xml.
Private Shared strcon As String = New AppSettingsReader().GetValue("ConnectionString", GetType(System.String)).ToString()
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<appSettings>
<add key="ConnectionString" value=""/>
</appSettings>
<system.diagnostics>
<sources>
...
So far i got this code but i am receiving error: "Object reference not set to an instance of an object."
on the line: config.AppSettings.Settings("ConnectionString").Value = "myconn"
' Get the configuration file.
Dim config As Configuration = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None)
' Update the setting.
config.AppSettings.Settings("ConnectionString").Value = "myconn"
' Save the configuration file.
config.Save(ConfigurationSaveMode.Modified)
' Force a reload of the changed section.
ConfigurationManager.RefreshSection("appSettings")
This is my app.config file looks like:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<appSettings>
<add key="Application Name" value="/MyApplication" />
</appSettings>
<connectionStrings>

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