New Post: Use environment variable in filePath in File Configuration Source

esaulsberry — Fri, 20 Nov 2009 16:55:55 GMT

Thanks for your reply. This is a huge deal, as being a good UAC citizen and using EntLib means placing the configuration outside of app.config. If you can't point to a known location using an standard environment variable you're left with having to write code to assign the location and modify the app.config during installation. Either I'm missing something or there are way too many programmers writing desktop apps not testing as a standard user with UAC turned on, AND testing with XP.

I've looked into the EntLib source and I think I see where it's calling

Environment.ExpandEnvironmentVariables

On the file trace listeners, and where it might be appropriate to call the same on the file configuration source, but the source for EntLib it daunting and making sure you're in the appropriate place isn't a no-brainer.

Environment.ExpandEnvironmentVariable

Hi,

As far as I know, using environment variable on the file configuration source thru config is not supported.

Hi,

Do you do this with remoting?

New Post: ObjectValidatorAttribute with TargetRuleSet

AvanadeSupport — Fri, 20 Nov 2009 08:24:04 GMT

Hi,

Actually it is exposed on the ObjectValidatorAttribute. There is a overload of the ObjectValidatorAttribute which accepts a string targetRuleSet. You could do something like this:

    public class MockClass
    {
        [ObjectValidator("A")]
        public SubClass SubClass { get; set; }

        public MockClass()
        {
            SubClass = new SubClass();
        }
    }

Hi
I created a library for accessing SQL Server and i reference the Microsoft.Practices.EnterpriseLibrary.Data

with app.config. It fails like bellow I do not get it why

Hi,

I'm not sure what do you mean by embedded in the solution, do you mean you have the oledb dll will be deployed together with your binaries? Do you use a custom provider? just like in these posts:

New Post: ObjectValidatorAttribute with TargetRuleSet

meboz — Thu, 19 Nov 2009 23:04:08 GMT

Ive been struggling with using the ObjectValidators with rulesets when using the attributes as per this stackoverflow question

I now see why the ObjectValidator doesnt work, and thats because when defining the validators in a config file, the objectvalidator needs a targetRuleset attribute.

Is there a reason this field isnt exposed in the ObjectValidatorAttribute?

New Post: Use environment variable in filePath in File Configuration Source

In order to allow a standard user under UAC to modify the EntLib Logging configuration, I've moved the location of the logs and the logging configuration to the \programData\MyCompany\MyApp folder. In the logging configuration, I can use an environment variable in the file path, like this:

<add fileName="%ALLUSERSPROFILE%\mycompany\myapp\myapp.log"

I'm using %ALLUSERSPROFILE% instead of c:\programData because of course you can't guarantee c:\programData is correct. Fortunately, using the environment variable here works. Unfortunately, it does not work in the app.config to point the EntLib to the configuration, and I've had to resort to using the hard-coded path. Is there a way to tell the File Configuration Source to use a well known system folder (Environment.SpecialFolder.CommonApplicationData)?

<enterpriseLibrary.ConfigurationSource selectedSource="File Configuration Source">

<add name="File Configuration Source" type="Microsoft.Practices.EnterpriseLibrary.Common.Configuration.FileConfigurationSource, Microsoft.Practices.EnterpriseLibrary.Common, Version=4.1.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"

filePath="c:\ProgramData\MyCompany\MyApp\MyApp.Logging.config" />

Would like this to be something like:

filePath="%ProgramData%\MyCompany\MyApp\MyApp.Logging.config" />

New Post: in Separate Config file

esaulsberry — Thu, 19 Nov 2009 20:04:07 GMT

I'm looking for something similar - a way to put the <system.servicemodel> configuration for a *win* app (or win service) that hosts a WCF service in a separate file configuration file. If it's left in app.config, and the application is installed under the \program files tree (where it's supposed to be), the configuration cannot be edited if UAC is turned on. I need a way to point WCF to it's configuration in \programData\mycompany\myapp\myapp.wcf.config

Lot of things we used to configure in the app.config break under UAC & standard users.

lpoinsot — Thu, 19 Nov 2009 09:03:19 GMT

Hello,

I'm using the DAAB to connect to a Sybase DB with OLEDB provider, my connectionstring looks like that

and the OLEDB driver is registered on the local machine. But I need to deploy my application on computers which don't have the oledb provider registered. Is there a way to tell DAAB to use a driver embedded in the solution ?

Thank you.

I believe the suggestions you made are ok. You can do away with most of the configuration and design dlls, just include those which you actually referenced in your project.

Deploying assemblies to GAC also improves the load performance as they are already verified but it would cause issues if there are other applications in your machine which uses a different version of entlib.

New Post: in Separate Config file

baskar_ram — Thu, 19 Nov 2009 05:00:37 GMT

Hi,

Thanks for your reply.

I cant edit the web.config to specify the configSource. And one more thing the other team have their own <system.serviceModel> entries in web.config. And i have to maintain my <system.serviceModel> entries in my separate config file. So the application can load the web.config file(tat stuff is default), and my config's <system.serviceModel> entries too.

Is there is any custom way of doing this?

Thanks in advance!

New Post: in Separate Config file

AvanadeSupport — Thu, 19 Nov 2009 02:33:32 GMT

You can use the configSource attribute in the web.config file and point it to the file containing the system.servicemodel section only. Is this an acceptable solution for you? (Note that the configSource attribute only works for a relative path)

zoisite — Wed, 18 Nov 2009 18:49:20 GMT

I have a small web site (1.5 meg) that is now using the Data Access Blocks, Exception Access Block and Logging Access blocks which is 2.3meg in the following DLL's:

Microsoft.Practices.EnterpriseLibrary.Common.dll
Microsoft.Practices.EnterpriseLibrary.Common.xml
Microsoft.Practices.EnterpriseLibrary.Configuration.Design.dll
Microsoft.Practices.EnterpriseLibrary.Configuration.Design.HostAdapter.dll
Microsoft.Practices.EnterpriseLibrary.Configuration.Design.UI.dll
Microsoft.Practices.EnterpriseLibrary.Data.Configuration.Design.dll
Microsoft.Practices.EnterpriseLibrary.Data.dll
Microsoft.Practices.EnterpriseLibrary.Data.xml
Microsoft.Practices.EnterpriseLibrary.ExceptionHandling.Configuration.Design.dll
Microsoft.Practices.EnterpriseLibrary.ExceptionHandling.dll
Microsoft.Practices.EnterpriseLibrary.ExceptionHandling.Logging.Configuration.Design.dll
Microsoft.Practices.EnterpriseLibrary.ExceptionHandling.Logging.dll
Microsoft.Practices.EnterpriseLibrary.Logging.Configuration.Design.dll
Microsoft.Practices.EnterpriseLibrary.Logging.dll
Microsoft.Practices.ObjectBuilder2.dll
Microsoft.Practices.Unity.Configuration.dll
Microsoft.Practices.Unity.dll
Microsoft.Practices.Unity.Interception.Configuration.dll
Microsoft.Practices.Unity.Interception.dll

The first time the site is used, there is atleast a 10 to 15 second delay that wasn't there before the Enterprise Blocks were introduced.

Is there anyware of increasing the startup performance? Like using the GAC, not including all the DLL's etc?

Thanks ... Douglas
