C# :: Reference Configuration Information From Within Multiple Class Libraries?
Mar 13, 2009
I've got a bunch of DLL projects that I'm pulling into my application, each contains their own Settings.settings/app.config. When I compile the app and run for debugging, everything works just fine, but come deployment time I can't get my DLLs to read their own settings files.I've been doing some reading and it has become apparent that there's a couple of methods to getting each dll to read its own configuration - one is to dedicate a .dll.config to the library and the other is to embed the dll's configuration in the process.exe.config.I'm having significant issues trying to implement either and I wondered if anyone has any good docs on this - there appears to be a shortage on the Net.
I'd like a separate .dll.config for each of the libraries if possible, but in a pinch, getting each of my libraries to read their own section of the process.exe.config will he right direction because I'm so close to rolling this application out but this stumbling block is causing me a significant headache.Edit: When I merge the configuration files, I start getting TypeInitializer exceptions when I initialize objects withing my libraries. This is likely just me being retarded, but does someone have a working example of a merged config file and some basic demonstrative code for reading it from multiple assemblies?

I designed 7 class libraries for 1 project.The project references all 7 libraries.3 of the 7 libraries make references to the other 4 libraries.I thought of just duplicating the code that's referenced in the other 4 libraries, but thats a lot of code.
Example:
PrjctA makes reference to LibA, LibB, LibC, & LibD.If LibA references LibB & LibC also will this fail?

We have several VB.NET websites running internal applications. These sites are often modified with minor changes, and are maintained on the server as uncompiled code. I'm looking for the best way to maintain classes so that we can reference them from multiple websites.
Specifically, we're looking to put some common functions (error logging, common database calls, etc.) into a centralized location where they can be maintained separately from the sites and called as needed. And we'd prefer to have this on the server as uncompiled code, so it can be uploaded without precompiling. I feel like I'm missing something obvious, but what is the best way to set this up?

good way to run windows script host code from vb.net? Im trying to run some dsf com components but they are only for the 64-bit version of scripting engine installed. I wish i could execute my code from vb.net but sometimes it doesnt want to work because im referencing the 32-bit version script control and not the 64-bit scripting environment.
So my goal out of this is to find a 64-bit scripting component dll or library that i can use for executing a wsf file thats mostly written in vbscript but has some xml from the windows script host.Once you eliminate the impossible, whatever remains, no matter how improbable, must be the truth. - "Sherlock holmes" "speak softly and carry a big stick" - theodore roosevelt.

I'm trying to implement the XACT engine in a VB.NET project. I'm pretty new to this stuff, but I can set up and use the normal DirectX libraries fine. However, I can't for the life of me work out how to set up/reference/import/include/whatever the XAudio2 and XACT libraries. All the dlls in the Aug2009 DX SDK say they can't be used as references in the project, and the only tutorials I can find are in C++ and use the .h headers, which, if I'm not mistaken, I can't use at all for VB.
I'm tearing my hair out over this because there literally seems to be no way that I can find to use the new sound stuff in VB! I'm imagining MS wouldn't actually allow that to be the case, so if someone can tell me what basic thing I'm doing wrong.

I'm creating an application that will utilize a lot of functions for performing scientific calculations. There will also be a lot of 3D and 2D rendering in my application. Hence i will have a lot of common functions that will be utilized frequently.
I have noticed that class libraries (DLL's) are utilized in applications similar to mine, and am wondering if i should utilize them in my application. The trouble is, i can't really think of what use they will be to me. The functions in my application will only be called upon by my application, so i do not need to make my functions accessible to others. The only other benefit i can see from using DLL's is reduced memory usage and .exe size.
Whats the benefit of using DLL's instead of just creating a bunch of modules in my application to store my functions? I have read that another benefit of using DLL's is they are easier to maintain and update as you can update the DLL rather than your entire application. I dont quite understand this, as if you are going to utilize new and updated functions you have added to your DLL's, then you will need to update the code that calls them as well. So again i don't see the benefit in using DLL's in my application.

I have an ASP.NET application. It resides within another ASP.NET application. I put my DLL in the other apps bin folder and have a subdirectory with my aspx files. I can't edit the main app's Web.config.
So where can I store configuration settings? For example, this is an app that will get deployed to various clients. I want to store the client name used for display in the headers and such. And the location of a logo file.

I'm creating a class library that contains a series of functions with Try...Catch blocks to handle errors. When i run another application that uses the class library, and call a function in the library using parameters that i know should cause an error (i.e. divide by zero), i don't get an exception thrown.
Can you not use Try.. Catch blocks in external libraries? If not, how are you suppose to handle errors in these functions?

I've just about finished my WPF app, but I just hit a hurdle: my app needs to be totally localized (I've achieved this using databinding/RESX files & multiple cultures), and the actual program does this My problem is that I have a window where you generate reports on your progress.It's designed so that programmers will be able to design their own 'report sections', using interfaces & class libraries.Just one problem though: when I use RESX files inside these class libraries, they won't actually change even if I set their culture to the relevant culture I want to test.

I'm looking to create a bunch of re-usable classes. I understand the strength of creating a DLL that is reusable, but I would rather keep them un-compilled. When adding an existing .vb file, visual studio makes a copy of that object instead of a simply reference.Is there any way to do this or creating a class library with .DLL the only way?

I've wrote a class library in vb. it only has a class called MathEx. Now when i add a reference to a test project, i had to refer to the class as MathEx.MathEx is there anyway i could refer to the class as simply MathEx? (in other words i do not wish to have the default namespace added to my class libraries)

i created a Class library (.dll) and loaded it as reference into a main project. In the code for the class i've handled exceptions using try..catch subs, however when debugging the main project exceptions that are handled in the DLL still get thrown! (the class ".vb" file gets loaded into the debugger and the line of the exception shows up)
Up till now i've found it useful that when an unhandled error occurs in the imported reference, it shows up in the main project with tracing back to the referenced class. But i dont want the exceptions that are handled in the reference class to be thrown when debugging the main project!
As you can see the exception thrown was handled with try...catch this class exception.vb belongs to the project that created the class library (.DLL that i referenced). i didnt even load the project that built the reference so it amazes me that it could find the coding class to begin with.

The coding that I have a problem with might make people think that I am creating some malware or something stupid. So the project I am doing is associated with iTunes. iTunes allows people to have one library. There is another way, but it is very confusing to some people, and very unreliable. So my project is that I will allow people to have multiple iTunes libraries on one computer. So the problem is this. In order to have an option to choose your library, I gotta make sure that iTunes is not running. So this is the script:
Code:
Private Sub CheckAndCloseiTunes()
retry:
'Custom class that includes the function to safely close iTunes
[CODE]...
So when I use the Threading.Thread.Sleep(2000) code, the form becomes unresponsive.

New to these forums but have been a lurker for a while. I searched through some "multiple monitors" threads but didn't find anything that fit my current issue, so I figured I'd pose it in a new thread. We have users with 4 monitor setups that are very particular about their screen settings. When we have to replace a PC for whatever reason, it is always a hassle getting their screen configurations the way they were prior to the switch. Is it possible to create a small VB app that will scan their current configuration, save a "settings" file, and re-apply the settings on the new PC? What I mean by configuration is screen resolution, setting the primary monitor, etc. Theoretically this sounds like it can be done, but I wanted some opinions on it.

I have a 'property management class' that contains several functions and properties. I have several other classes that use the 'management class' as a property to derive the value of several of its other properties.Is there a way for me to reference the outer class from the 'management class' functions without having to pass it as a parameter? I ask because several different classes can have this 'management class' as a property and am having a hard time typing the parameter.

If we are within the derived class then ofcource we can use MyBase keyword to access base class's object reference . That's fine , how can we take that base class's object reference outside that derived class's definition.My following code will explain what i want . Actually that is giving error right now, but it is explaining my requirement .
Public Class Base
Public x As String
End Class
[code]....
Actually there is error in ReadOnly Property BaseReference's Getter . Error is "Error 1 'MyBase' must be followed by '.' and an identifier. " how can i get base class object reference in Main method ?

I need to create a new instance of a class that needs a member of the calling class. But i can't pass a reference to the calling class through the constructor.The solution i am looking for is something like this:
Public Class ChildClass
Public Sub New(args)
_MyMember = GetMemberFromCallingClass()
[code]....
I want this to work without having to manually pass any references or variables from the calling class to the new instance of ChildClass.
