Re: Accessing the user.config file on a newly installed application from the installer itself

23-Jun-10 5:10

Dear all.

I want to access the user.config file from the installer itself, the problem is that I don't know how to get the path of the newly installed application. I know that the user.config file for my main application is somewhere in "'user'\AppData\Local\.... but I don't know how to access this area from the installer itself.
In my main application it is very simple, I just call:

Configuration _usrConfigLoc = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.PerUserRoamingAndLocal);

Inside the installer I have tried:

Configuration _usrConfigLoc = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.PerUserRoamingAndLocal);

This returns the path of the config file of the installer (and not my main application)

Does anybody have a way to find the freshly installed user.config file from the installer application?

protected override void OnAfterInstall(System.Collections.IDictionary savedState)
{
    string t_path = this.Context.Parameters["assemblypath"].ToString();
    Configuration _usrConfigLoc = System.Configuration.ConfigurationManager.OpenExeConfiguration(Path.Combine(t_path,"user.config"));
    //...
    base.OnAfterInstall(savedState);
}

Thanks for the quick reply, however this doesn't work exactly as I want to.... When running this code I get the C:\Program Files\..... folder and the corresponding .config file.

However I want to access the .config file which lies in:
"Users\user\AppData\Local\CompanyName\AssName++++\VersionNo\user.config"

Any ideas?

Application.UserAppDataPath

It'll return like follow:
"C:\\Documents and Settings\\mis-hongwenshi\\Application Data\\ccc\\WindowsApplication11\\1.0.0.0"

Thanks again for the very quick replies, however my problem is that I want to find the main application path and not the installer path.

If I call Application.UserAppDataPath inside the installer it gives me:
C:\Users\Kåre Tragethon\AppData\Roaming\Microsoft Corporation\Windows Installer - Unicode\5.0.7600.16385

I want to be able to find the main application path:
C:\Users\Kåre Tragethon\AppData\Local\Tragethon_Teknikk\EasyNetTools.exe_Url_mxn53vo4iinbepot2fslrsybsd0vtoiz\0.8.4.9

Let me know if anything is not clear and I will try to explain some more.....

How about this

AppDomain.CurrentDomain.BaseDirectory

I think you deploy the project use the clickonce,am I right?

Thanks again for the very quick replies, and for helping me out and sorry for my bad English and explanations.

No I don't use clickonce. I will do some more explaining:

I have a main project (main application) which can be installed on any computer. This application contains user settings (user.config) which lies in the following directory:
C:\Users\Kåre Tragethon\AppData\Local\Tragethon_Teknikk\EasyNetTools.exe_Url_mxn53vo4iinbepot2fslrsybsd0vtoiz\0.8.4.9

This is the standard location of user settings file, however when the main application changes version a new folder is created, e.g.:
C:\Users\Kåre Tragethon\AppData\Local\Tragethon_Teknikk\EasyNetTools.exe_Url_mxn53vo4iinbepot2fslrsybsd0vtoiz\10.8.4.9

I also have an installer application in my project (the standard VS built-in installer). When I un-install the application I want to access the user.config file and get all the settings from this file (and I will save all the settings in the TEMP directory) so that when I install the application again I am able to retrieve all the settings (access the user.config file and write all the previously saved settings).

Most often the reason for uninstall->install is that I have made a new version of the software and therefor I cannot rely on a static path to the user.config file, I will have to get it programmaticly.

How to import a namespace - 2 levels up?

23-Jun-10 7:47

Anyone else?

Hello,

So I have the following layout in my project:

Solution ('sol')
namespace A
------folder 1A
------------folder 1A1
------------------file Af.cs
namespace B
------folder 1B
------------file Bf.cs

Now, in file Bf.cs I want to call a method which is in file Af.cs. How can I do that? I can't create an object of type Af, because I cannot call the namespace A for some reason. I am getting a message namespace A cannot be found whenever I use: using A.1A.1A1;

The dashes above are there just to show the hierarchy ( indentation ).

Thank you!

If "namespace A" and "namespace B" represent projects, then you have to add reference to project A in project B (right-click project B icon -> "Add reference" -> tab "Projects" select project A and click OK).

You can have multiple (or nested) folders with the same namespace - so make sure you actually have those namespaces available on those folders.

I don't see where folders come into the picture.

Maybe you have a Java background, where there was a strong link between namespace structure and file structure; there is no such thing in .NET

Files reside in folders.
Types reside in namespaces.
You can have (parts of) more than one namespace in a file.
You can have a namespace spread over many files and folders.
The project holds files, and the compiler will locate and deal with all types in them.
And to locate types in some other project, you'd have to add a reference.
