XML Connectionstrings - database

<?xml version="1.0" encoding="utf-8" ?>

</configSections>
<connectionStrings>
<add name="Citrus_Welding.My.MySettings.CitWeldConnectionString"
connectionString="Provider=Microsoft.Jet.OLEDB.4.0;Data Source="C:\Citrus Welding\CitWeld.mdb""
providerName="System.Data.OleDb" />
</connectionStrings>
<startup>
<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" />
</startup>
</configuration>
I am looking at the connection string, I need the Data Source to = a selected file from another page by default... I tried & pagename.openfiledialog.filename & but I keep getting an error. Any ideas?

It appears that you're saying that you want the user to be able to set the Data Source at run time. If so then omit it from the connection string in the config file and set it like this at run time:
Dim builder As New OleDbConnectionStringBuilder(My.Settings.CitWeldConnectionString)
builder.DataSource = newDataSourceValue
Dim connection As New OleDbConnection(builder.ConnectionString)

How to resolve key/value pair with external .config file

I am specifying <appSettings> in my app.config file, I am adding
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<appSettings configSource="ShareAppSettings.debug.config"/>
<startup>
<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.7.1"/>
</startup>
</configuration>
ShareAppSettigns.debug.config is my external config file, which I am using on my local machine and I do not want to share it with the rest of my team.
ShareAppSettings.debug.config looks like:
<?xml version="1.0" encoding="utf-8" ?>
<appSettings>
<add key="clientID" value="11" />
<add key="clientSecret" value="11" />
<add key="tenantID" value="11" />
</appSettings>
Whenever I am trying to debug the main code:
private static List<string> AppCredentials()
{
string clientID = ConfigurationManager.AppSettings["clientID"];
string clientSecret = ConfigurationManager.AppSettings["clientSecret"];
string tenantID = ConfigurationManager.AppSettings["tenantID"];
List<string> appCred = new List<string> { clientID, clientSecret, tenantID };
if (clientID == null)
throw new Exception("ShareAppSettings.Debug.Config file was not provided in this repo.");
return (appCred);
}
For some reason I am not getting values for clientId, slientSecret nor tenantId. This code is a part of grasshopper Add-on for v6 template, and its running on .NET Framework 4.7.1. Whenever I copy the same code into a new C# console of a same framework, the code is built. I would truly appreciate if you could give me suggestions on how to solve this.
What "EnableWindowsFormsHighDpiAutoResizing" means and how can make this work?
Many Thanks
enter image description here
I suggest to use the file attribute (corresponding to the AppSettingsSection.File property) instead of the configSource attribute (corresponding to the SectionInformation.ConfigSource property) in the appSettings section.
configSource doesn't support other keys in the section, while appSettings may contain other keys, needed by the Application and possibly somewhere else (someone else may add/remove them - for testing purposes or any other reason).
The file attribute allows instead the presence of other key in the appSettings section.
Your app.config file can be:
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<appSettings file="ShareAppSettings.debug.config">
<add key="DpiAwareness" value="PerMonitorV2"/>
</appSettings>
<startup>
<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.7.1"/>
</startup>
</configuration>
Now the values are accessible by both opening a named configuration section:
appSettings.Settings[] returns a KeyValueConfigurationElement
Configuration config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
AppSettingsSection appSettings = (AppSettingsSection)config.GetSection("appSettings");
var kvpClientID = appSettings.Settings["clientID"];
var kvpClientSecret = appSettings.Settings["clientSecret"];
var kvpCenantID = appSettings.Settings["tenantID"];
string clientID = kvpClientID.Value;
and directly, using ConfigurationManager.AppSettings - a NameValueCollection - which returns the value of the specified key:
string clientID = ConfigurationManager.AppSettings["clientID"];
string clientSecret = ConfigurationManager.AppSettings["clientSecret"];
string tenantID = ConfigurationManager.AppSettings["tenantID"];
As a note, using the file attribute, your ShareAppSettings.debug.config doesn't need (but it's not forbidden) the XML header, it can be just:
<appSettings>
<add key="clientID" value="11" />
<add key="clientSecret" value="11" />
<add key="tenantID" value="11" />
</appSettings>
Secondary note:
you can set the file attribute to point to another file at run-time and refresh the appSettings values to updated the configuration.
Note that, if a file attribute was already set, all values contained in that .config file are not dismissed, but instead moved to the [Application].exe.config file, to become part of the <appSettings> section (thus, they are preserved).
Another reason why using the file attribute may be preferable.
var config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
var appSettings = config.AppSettings;
appSettings.File = "SomeOtherFile.config";
config.Save(ConfigurationSaveMode.Modified);
ConfigurationManager.RefreshSection("appSettings");

Delete files older then X day.. BUT not by date modified

I have a config file for an .exe my workplace built where you can specify deleting of files (specifically retaining the last say 30 days files in my test here [logs and sql are fine]) and it even clears out sub folders. however it is deleting by date modified, so newer folders with some old remnents of data are getting the old remnents deleted.
Folder1:
File: Modified:
File 1 2018/02/02
File 2 2010/05/06
File 3 2018/02/01
Folder 2:
File: Modified:
File 1 2011/12/30
File 2 2006/01/16
File 3 2018/02/02
Would leave:
Folder1:
File: Modified:
File 1 2018/02/02
File 3 2018/02/01
Folder 2:
File: Modified:
File 3 2018/02/02
Is there anyway to change this so it retains the last 30 folders and contents,, deleting everything else?
This is the contents of the "cleaner".exe.config file I have:
<?xml version="2.0" encoding="utf-8"?> <configuration> <configSections> </configSections> <!-- Make sure that every new location has a name with an increasing number e.g clear 1 -->
<appSettings>
<add key="connstring" value="Data Source=localhost;user id = *****;password = *****;Initial Catalog =Database;" />
<add key="sqldays" value="180" />
<add key="LogLocation" value="C:\File\Logs\Cleaner\" />
<add key="clear" value="C:\Directory\Logs,90" />
<add key="clear2" value="C:\Directory\CSV\Backup,30 " />
<add key="fileExtensions" value=".txt,.csv,.log,.fmt,.hdr,.Log" />
<add key="ClientSettingsProvider.ServiceUri" value="" /> </appSettings> </configuration>
Just to close this out it didnt matter about the modified date, the files just needed to 'be gone' so I added a few more directories to the config file and let it loose.
Example:
<?xml version="2.0" encoding="utf-8"?> <configuration> <configSections> </configSections> <!-- Make sure that every new location has a name with an increasing number e.g clear 1 -->
<appSettings>
<add key="connstring" value="Data Source=localhost;user id = *****;password = *****;Initial Catalog =Database;" />
<add key="sqldays" value="180" />
<add key="LogLocation" value="C:\File\Logs\Cleaner\" />
<add key="clear" value="C:\Directory\Logs,90" />
<add key="clear2" value="C:\Directory\CSV\Backup,30 " />
<add key="clear3"value="C:\Directory1\CSV\Backup,30 " />
<add key="clear4" value="C:\Directory2\CSV\Backup,30 " />
<add key="fileExtensions" value=".txt,.csv,.log,.fmt,.hdr,.Log" />
<add key="ClientSettingsProvider.ServiceUri" value="" /> </appSettings> </configuration>

RIA Service Error in a Silverlight Application

In a very simple Silverlight Application I have a DomainService Class which has a single method that returns a list of Letter Objects.
The application works fine when I run it in VisualStudio. However, when I publish it to a folder on my Windows 10 local machine and run it using IIS (version 10.0.166299.5) I get the following error:
The remote server returned an error: NotFound.
at System.ServiceModel.DomainServices.Client.OperationBase.Complete(Exception error) at System.ServiceModel.DomainServices.Client.LoadOperation.Complete(Exception error) at System.ServiceModel.DomainServices.Client.DomainContext.CompleteLoad(IAsyncResult asyncResult) at System.ServiceModel.DomainServices.Client.DomainContext.<>c__DisplayClass1b.b__17(Object )
I supect this is due to something being wrong in missing in my WebConfig file. My WebConfig Currently looks like this:
<?xml version="1.0"?>

Letter LetterC = new Letter { ID = 3, Statement = "Peter" };
letters.Add(letterA);
letters.Add(LetterB);
letters.Add(LetterC);
return letters.AsQueryable();
}
}
}
The error was due to the problem that .svc file wasn't being served.. The problem got solved with the kind help from the Kyle Abraham on Experts Exchange.
https://www.experts-exchange.com/questions/29084691/RIA-Service-Error-in-a-Silverlight-Application.html
The solution was to add the following line to the webserver section of the Webconfig
<handlers>
<add name=".svc" verb="*" path="*.svc" type="System.ServiceModel.Activation.ServiceHttpHandlerFactory, System.ServiceModel.Activation, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" />
</handlers>
I'm not sure, its a guess as I have not used RIA for awhile, but I think letters needs to returned as something other than queryable... try ToList() which causes the query to execute, and the payload is complete with the complete enumeration that was retrieved from the database. Remember, this is a remote call from a client, not a local one that can extend the queryable.

Can't insert into SQL Server table with log4net AdoNetAppender

I am trying to understand how log4net works so I've added this to my app.config (I should add that Console Appender and FileAppender work perfectly, I only have trouble with the AdoNetAppender).
How can I debug this, to see if at least the connection to db succeeds?
The problem is the INSERT statement isn't executed.
I should add the
Data Source=MyWorkgroup\SQLEXPRESS;Initial Catalog=MyNewDatabase;User ID=juan;password=juan,
works perfectly when I try to connect to SQL Server manually, so not sure if that's the problem.
Also, the ConnectionType was taken from the official site:
https://logging.apache.org/log4net/log4net-1.2.11/release/sdk/log4net.Appender.AdoNetAppender.ConnectionType.html
<?xml version="1.0" encoding="utf-8" ?>
<configuration>

</configSections>
<log4net>
<appender name="AdoNetAppender"
type="log4net.Appender.AdoNetAppender">
<bufferSize value="10" />
<connectionType value="System.Data.SqlClient.SqlConnection, System.Data, Version=1.0.3300.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" />
<connectionString value="Data Source=MyWorkgroup\SQLEXPRESS;Initial Catalog=MyNewDatabase;User ID=juan;Password=juan;Pooling=False" />
<commandText value="INSERT INTO Logs([logDate],[logThread],[logMessage]) VALUES(getdate(),'1','1')" />

</log4net>

Later edit (after using the debug method recommended by David):
haacked.com is indeed extremely interesting, great tip! However, it seems that it's describing what I'm instructing log4net to log, but not the result of those actions(?), if I'm reading this well (no failed/or succeeded?)
e.g.

How do I read a custom section in app.config from codebehind?

I have an app.config file that stores values in a few different sections. I have these snippets:
<configuration>
<configSections>
<sectionGroup name="someDataAccessLayer">
<section name="databaseConnectionStrings" type="sometype" />
</sectionGroup>
</configSections>
<someDataAccessLayer>
<databaseConnectionStrings>
<databaseConnectionString name="someSQL"
value="database=somedatabase;Integrated Security=False;User Id=sa;server=someserver;Password=somepassword/>
</databaseConnectionStrings>
</someDataAccessLayer>
How do I read the connection string in the codebehind? Specifically the value which is
database=somedatabase;Integrated Security=False;User Id=sa;server=someserver;Password=somepassword
Thanks for your help! Please let me know if the question is still unclear.
Your configuration section will be associated with some .NET class to handle it:
<configSections>
<sectionGroup name="someDataAccessLayer">
<section name="databaseConnectionStrings" type="sometype" />
</sectionGroup>
</configSections>
So to read the settings from the <localeSettings> section, you need to use the ConfigurationManager (add a reference to System.Configuration to your project) to get those settings into an instance of that class:
sometype cs = ConfigurationManager.GetSection("someDataAccessLayer/databaseConnectionStrings") as sometype;
Now you have an object of type sometype that contains all the settings in that config section. One of those properties will be a list of database connection strings, which you can now enumerate and find the appropriate one and read it's .Value property.
App.Config Settings:
<configuration>
<configSections>
</configSections>
<connectionStrings>
<add name="MyApp.LocalConnectionString"
connectionString="Data Source= .\SQLEXPRESS;Initial Catalog=DBName;Integrated Security = true"
providerName="System.Data.SqlClient" />
Access at DataLayer using the ConfigurationManager as:
// add reference
using System.Configuration;
// then access connection string in your class
private static string strConnectionString = ConfigurationManager.ConnectionStrings["MyApp.LocalConnectionString"].ConnectionString;
