I have a project based on the Chris Hammond, Christoc, module template. I have a ton of code that I use to access data an external database. In my repositories I change the database from the default to whichever I need for that particular object. I do so with code that looks like this:
using (IDataContext ctx = DataContext.Instance(MyModuleSettingsBase.DATABASE_CONNECTION_STRING_KEY))
{
var rep = ctx.GetRepository<Product>();
products = rep.Get().ToList();
}
The default database is switched in the call to .Instance(). The repositories are used by my custom DNN modules. The repository is part of the solution that contains multiple custom modules. When I compile and install using the Extensions part of DNN, everything works well. In the code above, MyModuleSettingsBase.DATABASE_CONNECTION_STRING_KEY is found in a file MyModuleSettingsBase.cs file of my module solution. It is set to a simple string like "ProductDatabase". In the solution for the base DNN install (not the module solution), within the web.config file, there is a value in <connectionStrings> with name="ProductDatabase" which contains the actual connection string. This all links up fine on the DNN website.
Now I am writing a console application that does some monitoring of the site. I want to access the database to check values in the product table. I would like to reuse all of the repository code I have written. In an attempt to do so, I added a reference to the MyModules.dll file so I would only have one copy of the base code. This works to give me access to all the objects and the associated repositories but when I attempt to query data it fails. When debugging I can see that it fails on the line:
using (IDataContext ctx = DataContext.Instance(MyModuleSettingsBase.DATABASE_CONNECTION_STRING_KEY))
When viewed in a debugger, the string value MyModuleSettingsBase.DATABASE_CONNECTION_STRING_KEY is correctly set to "ProductDatabase" but the code is unable to link this with the actual connection string. I don't know where it would be checking for the connections string when running from my console application. I attempted to put a <connectionStrings> section into my App.config file but this didn't do the trick.
Is it possible to have MyModuleSettingsBase.DATABASE_CONNECTION_STRING_KEY map to the connection string in an external application which references the DLL?
If so, where can I set the value of my connection string so it matches up to the key value stored in MyModuleSettingsBase.DATABASE_CONNECTION_STRING_KEY?
I was faced similar problem 3 months ago, at that time I want to use DNN core libraries in my console application but I was failed.
I placed my queries in DNN official forum website and I got a valid response from Wes Tatters (DNN MVP).
Here is the post link: Reference URL
As your requirement of monitoring, I suggest you to create DNN Schedule Application. You can schedule it within DNN (Host->AdvancedSettings->Schedule), even good point is that you can use your repositories (DNN Libraries) in that schedule application.
I hope it solved your problem. Let me know if you have any questions.

I have working web client, it uses "wwwroot/appsettings.json" file for its configuration.
Now I would like to override just single settings using environment variable for it (as an example, in reality there will be many, arbitrary, overrides). Is there ready to use mechanism, similar to ASP.NET Core server (all it takes is calling extension method and combining json, env. variables)?
I am not asking about multiple .json files and switching between them depending on ENVIRONMENT variable, it is completely different scenario.
So far I didn't find anything even close, so thinking about DIY approach I see an ugly path -- moving client configuration file into hosting server, adding main node in client .json file like "client", using environment variables with prefix "client", merging those data using ASP.NET server mechanism, dumping it back to file for the client usage. And hoping it will work :-).
So I followed DIY path :-) If anyone like it here are the steps:
create 3 files with empty JSON at web client wwwroot -- appsettings.json, appsettings.Development.json and Production version as well
put your entire web client config in appsettings.json at hosting server at "CLIENT" node for example
in your server Startup constructor create configuration as usual, but then fetch entire "CLIENT" section and "jsonize" it back (see: https://stackoverflow.com/a/62533775/6734314) -- convert it to string and write to $"wwwroot/appsettings.{env.EnvironmentName}.json" (where env is IWebHostEnvironment)
And that's it -- I tested it in Development mode and in Production. The only drawbacks I see are:
it looks weird :-)
when executed using VS the written file is put not relative to binary file, but relative to project -- so when you are done you have to delete newly created file (otherwise on the next run VS will complain about conflict between two static files)
You override the settings using env. variables at server side using "CLIENT" prefix, and the rest is as usual.
For the record, I am not saying this is perfect, but I didn't look for anything more than I asked in my question. What I would like to do however is to reduce the number of steps, or even better to use some already existing mechanism. I will be grateful for the improvements/tips within those areas.
I'm using the AllScripts HelloWorld TouchWorks C# Project, as provided on their site. I've also created a valid application, using the svcUsername and svcPassword on the app.config file to log and added my own appName instead of the default web20.
Didnt change anything else, tried with many different application ID's, all trying to log into the default sandbox server in the example and some trying other sandboxes.
Regardless of what I do, I keep getting
Error: Service Application not licensed on this server!
Despite this being a sandbox server, thus suppouseably accessable to all applications.
What did I do wrong?
edit: Tried to do the same in Slueth, I get the same error.
It's more simple than it seems. Sandbox servers DO require licenses. Talked with the staff, they're nice people, so they manually added me after a few explanations of my requirements.
I need a little help with the C# example program of Google-Drive...
I used this so-called "tutorial"/"example":
https://developers.google.com/drive/examples/dotnet
And the code from here:
https://code.google.com/p/google-drive-sdk-samples/source/checkout
I uploaded my (only slightly modified) sourcecode here in case anybody doesn't have Mercurial (I didn't have Mercurial and no admin rights to install it either, and Mercurial is the only way to get the sourcecode...):
http://verzend.be/elt0k13enraw/DrEdit.rar.html
I always get
"Ressource cannot be found"
Requested URL: /oauth2callback
I don't find this astonishing, as no oauth2callback controller or handler is implemented...
I tried adding a Controller called oauth2callbackController and redirecting to another action in oauth2callbackController.Index, doing
return new RedirectResult("/about/about");
But that only creates a NULL-reference exception.
So i figured, maybe the wrong controller and redirected to
return new RedirectResult("/drive/Index");
But that only creates an infinite loop of redirect -> allow -> redirect - allow -> etc.
BTW, the config to change the API key + REDIRECT_URI is in
Models\ClientCredentials.cs
Note:
The problem aren't my modifications.
The sample also didn't work unmodified, with the exact same error.
All I did was removing EntityFramwork references, and throwing "Not implemented exception" when a method using entity was called.
Edit:
Additional information:
What I really wanted to do in the first place is to write a console service that exports my database, LZMA-compresses the exported content, encrypts that with OpenPGP, and uploads the database of my server to Google drive every day at 24:00 o'clock, without any user input.
I got export working without a problem, i got the LZMA compression working without a problem, I got the encryption with PGP working without a problem.
After the end of the working day (grrrr), when I was at home, I was even able to download the example-code with the mercurial installed on my Linux-machine at home, and bring it on the windows machine using SMB...
But now I can't get the sample for the Google-drive SDK working...
And moreover, what I really need is an example for a console service/daemon, not a web-application.
When I created the API key, I saw one could create a key for a service, but there is no example on how to write a Google-Drive service (console application), and no useful documentation as well (yea there is a reference, but it's only a reference, IntelliSense provides about the same)...
When configuring your app in the API Access tab of the APIs Console, you had to set the root (/) of your web server as the redirect URI and not /oauth2callback.
Assuming that your app is published at www.example.com, just go back to the APIs Console and set it to www.example.com instead of www.example.com/oauth2callback
I am currently running a WCF service on an AppFabric server and my application needs to load a the web.config file dynamically to retrieve custom configuration sections.
On my development machine I can just load the configuration like this:
WebConfigurationManager.OpenMappedWebConfiguration(webMappedFile, virtualPath);
But on the test machine (AppFabric server) I am getting an exception and it seems that I need to specify a third parameter which is actually the site the web application is running on:
WebConfigurationManager.OpenMappedWebConfiguration(webMappedFile, virtualPath, "MySite");
So I tried to hard code it and it worked. Anyway this is not acceptable, so I need to dynamically provide the site to the WebConfigurationManager because I do not on which site the service will be running in the future. Do anybody knows how to achieve that?
Thanks.
If you are running this code as part of handling a request you could use:
Request.ServerVariables("server_name")
see: http://msdn.microsoft.com/en-us/library/ms525396(VS.90).aspx
Edit based on your comment
The parameter that you need is the Site Name, not the machine name, your code be running on many machines. If the code is running somewhere where it no longer knows that it is on a web site, then it is difficult for it to get the name of the web site that it is running on.
You then have two options:
Send the name as a parameter from a layer that has httpconext
Not sure if this will work: but you could try adding a reference to system.web to your project. It may compile, but you could get a null reference exception when you run it. Probably worth a try.
How about Server.MachineName
I am trying to develop a website with C# ASP.net MVC. It's my first time using Visual Studio, C# and ASP.net so I have lots to learn but so far so good.
So far... I started a C# ASP.net MVC project and added a database by going to the Database Explorer and clicking "add connection". I then did some standard CRUD controllers and views.
I am at the stage where I want to implement User authentication. I'm a bit confused here. I am trying to make a custom Membership Provider. So I added it to my web.config file with the correct connection string etc.
When I run the project and go to register I get an error. "Could not find stored procedure 'dbo.aspnet_CheckSchemaVersion'."
From searching, I see lots of people have this problem and they always reference their hosting. People say this (http://weblogs.asp.net/scottgu/archive/2005/08/25/423703.aspx) is their solution but when I try pick a database I get an error. Not even sure of my server name.
So at this point I am wondering, did I set up the database right?
EDIT
Adding in a few pics to show exactly what I am doing. This is the aspnet_regsql.exe:
This is the provider with connection string, taken from an example on one of the links given.
This is my customized provider with connection string pointing to the last image.
This is a screen cap when I run the project and go to the default project Account register action:
and finally, this is the error screen when I submit
EDIT
Another update..
I sorted something out but I am not sure if it is correct. I am now getting an error when the page loads: "Invalid object name 'dbo.Tag'"
In order to solve this problem the only thing you need to do is create an application services DB. You can achieve this by running the following command from your Visual Studio Command Prompt
aspnet_regsql
Anyways it seems that your "custom provider" isn't using a custom structure for your DB, which might be the reason why you weren't expecting this error.
If you are using the default implementation, you can access to the user administration using ASP .NET Configuration, located on your project menu in visual studio.
The default implementation uses the following conn string keyword
LocalSqlServer
The are many ways of implementing the membership provider. My guess is that probably this conn string is not pointing to your aspnet services db, you could do something like this to specify a custom location for this db
<remove name="LocalSqlServer"/>
<add name="LocalSqlServer" connectionString="Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\aspnetdb.mdf;Integrated Security=True;User Instance=True" providerName="System.Data.SqlClient" />
I made a blog post regarding this topic: How to use MembershipRole Provider and when to use custom implementations
It's hard to figure out anything from your post.
but when I try pick a database I get
an error.
You can check your server name in Surface area configuration or Sql Server Configuration Manager. If you installed Visual Studio it's probably YOUR_MACHINE_NAME\SQLEXPRESS. You can connect to it using Windows Authentication. You could also write localhost,1433 instead, but that would require enabling TCP/IP first(it's disabled by default) and setting the port number first(which in most cases is already set).
