如何在中添加应用程序名称?
这是我的 app.config 文件,如下所示:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<appSettings>
<add key="Application Name" value="/MyApplication" />
</appSettings>
<connectionStrings>
<add name="frmStartup.My.MySettings.HDIMembershipProviderConnectionString"
connectionString="Data Source=.\sqlexpress;Initial Catalog=HDIMembershipProvider;Integrated Security=True"
providerName="System.Data.SqlClient" />
</connectionStrings>
<system.web>
<membership defaultProvider="HDIMembershipProvider">
<providers>
<clear/>
<add name="HDIMembershipProvider" type="MyApplication.HDIMembershipProvider, MyApplication"/>
</providers>
</membership>
</system.web>
<system.diagnostics>
<sources>
<!-- This section defines the logging configuration for My.Application.Log -->
<source name="DefaultSource" switchName="DefaultSwitch">
<listeners>
<add name="FileLog"/>
<!-- Uncomment the below section to write to the Application Event Log -->
<!--<add name="EventLog"/>-->
</listeners>
</source>
</sources>
<switches>
<add name="DefaultSwitch" value="Information" />
</switches>
<sharedListeners>
<add name="FileLog"
type="Microsoft.VisualBasic.Logging.FileLogTraceListener, Microsoft.VisualBasic, Version=8.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a, processorArchitecture=MSIL"
initializeData="FileLogWriter"/>
<!-- Uncomment the below section and replace APPLICATION_NAME with the name of your application to write to the Application Event Log -->
<!--<add name="EventLog" type="System.Diagnostics.EventLogTraceListener" initializeData="APPLICATION_NAME"/> -->
</sharedListeners>
</system.diagnostics>
</configuration>
我正在尝试使用 HDI 成员资格提供程序,这是我的用户表结构:
在我最近提出的问题这里Oded
提供了 我试图找出问题所在我的 Insert 语句,我重新修改了它,我的数据库结构中有一个 ApplicationName 列,我需要指定它。(因为它不应该为空值)
现在我需要默认添加我的应用程序名称以输入数据库,因为我们为 web.config 执行此操作。
这就是我的意思。
我需要将该 MyApplication 添加到我的 app.config 文件中。
那么我该怎么做呢?
这就是我尝试将用户详细信息输入数据库的方式,但它没有输入单个值
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
任何人都可以指出我在哪里犯了错误。
这是我在输入数据库时得到的最终结果:
为了更简短和清晰,我需要使用 HDI 会员资格提供商将上面显示的用户详细信息输入到我的数据库中。

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.

有一种更好的方法,可以使用以下步骤:
1) 将
System.Configuration
的引用添加到您的应用程序中。2) 将以下块添加到 app.config 文件的
configuration
部分中:3) 检索该值并在需要时通过以下代码使用它(所示答案中的示例):
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:3) Retrieve the value and use it where needed with the following code (example from your answer shown):
将 AppSettings 部分添加到您的 web.config
Add a AppSettings section to your web.config
经过一番努力后,我自己解决了这个问题,并找到了解决方案,我以这种方式更改了我的代码:
并以这种方式添加另一个参数:
我知道这不是最好的方法如果有人找到任何其他最佳解决方案,请让我知道。
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:
And add another Param this way:
I know this not the best way If anyone found any other best solution let me know.
