I have written a vb.net class library that pulls the url for a web service out of my.settings. However, at runtime it no longer bothers to read the class.dll.config file that it made.I want to deploy this dll in different environments and be able to custom choose the relative webservice via the class.dll.config file.
View 3 RepliesGot a solution with 3 projects, a Web Service, a WinForms (MyUI), and a Class Library (Foo).
MyUI calls methods in the DLL that access the web service. The DLL has project config settings that store the URL of the web service. I compile the solution and it compiles all 3 projects. In the DLL's bin dir it puts the foo.dll and foo.dll.config files. However, in the WinForms bin dir it puts the MyUI.exe, MyUI.exe.config, and foo.dll; it doesn't include the foo.dll.config. When I run the MyUI.exe from its bin dir, it appears to work, and is obviously getting the config settings from somewhere because it doesn't crash and successfully contacts the web service. However, if I copy the foo.dll.config file into the MyUI's bin dir, and change config settings and re-run, it appears to ignore my changes completely.
In the Class Library I setup the config settings through the project properties dialog under the Settings tab. I access them from code using My.Settings.
How do I modify the config settings post-compile?
I have a Class Library project with a appSettings.config file included into the project. The file is not embedded. So I have a ClassLibrary.dll with a appSettings.config beside in the bin.I have another project which is a Web Service. It has a reference on ClassLibrary.dll with a Copy Local=true. When I build the Web Service, the ClassLibrary.dll is brought into the bin of the Web Service. However, the .config doesn't follow.Do I need to do some postbuild event to copy the .config file or there is another setting I can set?
View 3 RepliesI have a class library (Named ADI), that needs some configuration settings from the project using it (like connectionstring, filesystem locations etc).
I want to define these settings in my Windows Forms/Web Projects App.Config or Web.Config, like other settings.
Here is part of my app.config for my windows forms application:
<applicationSettings>
<PhotoImportRobot.My.MySettings>
<setting name="ADIImageRoot" serializeAs="String">
[Code]....
I was dangerously close to high-jacking another thread, so I thought I should create my own. We make class libraries so we won't duplicate code, but what about settings? I have a large solution that I've created a project in for common material, which includes an app.config. The problem is that a class library isn't an "app" so my functions can't get to the values. How do I get around this?
View 20 RepliesSay I have a Class Library project with its own .dll.config, and a forms application. I want to confirm that it is impossible to reference the .dll.config file from the .exe.config file and still use My.Settings.
For example: I have SomeClassLibrary project, with SomeSetting that I can access through My.Settings.SomeSetting. I also have SomeFormsApp project. This is what I want my SomeFormsApp.exe.config to look like:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<configSections>
[Code].....
From my readings, this seems impossible. I either need to copy the content of SomeClassLibrary.dll.config into SomeFormsApp.exe.config, which is tedious and error prone when copying from multiple class libraries, or I need to use ConfigurationManager, which bypasses My.Settings and its typed, Intellisensed goodness.
I'm having trouble with my application settings and I'm wondering if anyone else has seen this.
I have a Librabry with a connection string. In the project for the library it has its own app.config:
<configSections>
<sectionGroup name="applicationSettings" type="System.Configuration.ApplicationSettingsGroup, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" >
<section name="OBInfrastructure.Settings" type="System.Configuration.ClientSettingsSection, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />
</sectionGroup>

I am trying to access appSettings using the following syntax and I have used it before in my many website projects but not in a class library project. In this class library project I cannot even access the AppSettings Keys. Is there any way I could access the AppSettings Key from my class? Is the class library project's app.config or project structure behave in a different way?

I have already added Project Reference to System.Configuration and imported in my class. When I run my code it says, "Object not set to an instance of any object".
Added for my quick reference.When you use the following code to retrieve the values from config file in a library project.
Value = Configuration.ConfigurationManager.AppSettings("KeyName")
The application will look for this key in AppSettings section of calling assembly and may lead to unpredictable results.

View 6 RepliesOur main application has both a asp.net and winforms component. There is a class that is used by both sides and needs info from either the web.config or app.config files. The class itself does not know if it's on the client side or on the web server (at this point). We are getting errors when it's attempting read app.config when it's on the web side. Is there a way for the class to tell if it needs to read web.config or app.config?

View 1 RepliesI have a class library in VB.NET that does a NET-envelope for an USB device driver.There is only one function of that driver that I could not envelope in a traditional class, but I had to put it in a Windows Service as described here:Sharing a class property (field) between applications.The Windows Service works fine, but I have now two projects for my NET-envelope: the one with the class library, the second with the windows service and I do not like the idea to maintain two distinct projects for the same driver.Is it a good practice (or even if possible) to add a windows service class to a normal class library (without creating its own project as described in the vb tutorial)?I know, in any case I should create a separate setup only for the windows service, but in this way I could have together all the classes that envelope my usb device driver in only one project.
View 1 RepliesI've createda vb.net class library where I've defined a number of small classes... nothing complicated, just working with strings, sending emails, etc.In another project, I reference the class library and I'm seemingly able to create an instance ofone of tclasses - intellisense shows me all of the plic properties, methods, etc... all looks perfect. No compile errors at all, nothing b gumdropsand lollipops.When I run the app I'm working on that references the class library, it fails at the point where I'm creating an instance of the class and gives me a vague exception, "System.TypeLoadException".
View 2 RepliesI'm posting this there is a relationship with my previous post [URL]
I have two projects, namely:
1. Project1 (Windows Application)
2. Project2 (Class Library)
in Project2 there are several classes:
* frmLogin.vb
* frmCustomer.vb
* clsGlobals.vb
in my case, I want to frmLogin.vb and frmCustomer.vb not called in Project1 and I can only call is clsGlobals.vb
I have made a class using New->Class Library. I have 2 constructors, 1 function (that computes length of circle), one subroutine that computes area of circle, and main subroutine.

My problem is when I try to run the program: No errors of syntax.
What I must do? I need to right click in solution explorer add new item->add->class and copy here this code?
After I write the code I chose from the vb menu: Build->Build Solution_name
Before writing the code I choose File->New->and selected class library then save all to save as a project.
Or class library is only a dll file that runs with a windows forms application. (that is added after i write the code for write library).

there's a lot of dlls i've got one in the Release folder and one in the Debug folder under bin, there seem to be one in the obj folder as well.they all seem to work fine, but which should be the correct one?
View 4 RepliesI have two projects; A and B, where B needs to use some classes that are in project A. Hence, I added B to A's solution, and in B I added a reference to project A.
Is that sensible? Or should I rather put those classes in a class library?
I see that if I further want to open form/program B from a menu option in project A, then A needs a reference to B. Which would not be possible if B already had a reference to A. However if I use the class library for the common classes, then it's ok as B doesn't need the A reference.
Does this sound logical? It would be nice to know what are typical reasons for putting projects in the same solution, and if it's advised to use libraries aggressively to refactor common code between two projects, even if it's just a couple of classes.. Yet I've never made my own library, so a bit unsure on when to use it.
I'm merging two of my projects that can share a lot of the same classes into one solution with two web applications and a shared class library.
I've literally just dumped all the classes into the class library project and as expected I've got a ton of errors to fix. My main problem at the moment is the connection string. Currently I have this (which is obviously not going to work):
''' <summary>
''' Initialise the data access layer by loading the database connection string from the Web.Config file

View 2 RepliesI'm in the midst of developing a class library DLL for a third party application. On my machine, the developers machine, things are going along smoothly. I can compile/build and my DLL is loaded, and thus works as expected.
I've been copying the contents of the Release directory from C:Solutions...Release to C:ProgramDirectory. I realize now that my DLL is loaded into memory from the Release folder, and not the folder I copied it to.The point being of course, I want to distribute this third-party add-in to my users. And sure enough when I try that, presumably the DLL isn't loaded into memory and thus not available to the user, like it is on my machine.
I tried the first obvious thing and registering the DLL on the user's machine, but that failed."The module "..." was loaded but the entry-point DLLRegisterServer was not found." It's apparent I am missing some key step or caveat when it comes to developing this class library.
I have two classes in two files in a class library project, they are:

I`ve made a .NET component in C#. After that, i`ve created a class library in VB.NET and added this C# component and a couple of buttons to the library (creating another component now with buttons). So far, so good.The problem is: when i use this final component (vb.net class library), i want to link all MouseClick Events of its own components (buttons and C# component). In other words, when i add this final class library to my VB solution, it has its own MouseClick event. But when i click inside it doesnt raise the click event unless i do not click in the buttons or in the C# component inside it. I want to raise this event in the application wherever i click (inside or outside its own components).
View 14 RepliesMy objective is to take a .vb class file that is used on multiple local applications/web sites and convert it to a .dll file that would would be deployed to the servers that we use.The code all works, I can build my class library project with Visual Studios 2008 Pro and end up with a DLL.I can then drag and drop the DLL into any application or website and use it successfully What I'm missing is how to compile it correctly so it will do two things;
1. Get it to show up as a .NET component
2. Get it to NOT scream at me when I try to reference it.
I think part of my problem is that I've been looking up assemblies and dll's when maybe I should have been looking at component authoring.No, I don't want to just stick with the drag and drop into local bins. I might as well just copy and paste the original .vb at that point.
