VS 2005 Access Settings In A Class Library?
Jan 1, 2010I have created a Class Library project to create a VB.net 2005 DLL file. I am trying to access My.Settings in this class library project and not able to. How would I do this?

View 8 RepliesI want to change my class library's settings from an another program. For this, I've made a Public property in my class library. It worked right. But this is not my question. I wonder this is a right method? Can I access a class library's settings (My Namespace) from other project directly?

Say 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>
[Code]...
Solution has 3 Class Libraries and 1 Windows Form application projects. For no apparent reason, one of the Class Libraries keeps loosing its Settings. These are primarily configuration strings. When I try to add them back in the IDE, they disappear again without explanation.
View 5 RepliesA while back, I wrote my own settings provider because I was having problems persisting settings in a class library. (Note - I had no problems persisting settings from an application).Today, I just did a test of persisting class library settings and it worked, without my custom provider.The test is:
(1) Create a class library
(2) Add a setting - 'Name'
(3) Add a class with a public shared property 'Name' that reads and writes to the setting 'Name'.
(4) Create an application that references the class library, and use the shared property to read and write the 'Name' setting.
I'm sure that before the 'Name' setting would persist while the application was open but after I closed it and re-opened it, the setting would revert to the default.This is not happening now and I'd like to be sure that I was being an idiot before and not an idiot now.
ETA: I've noticed that the first time I create a test app, change the setting, close, and reopen, the setting is not persisted. Subsequently it is. May be I gave up after one try before. Any ideas why it's not persisted the first time?
ETA2: As an example, I have a class library called 'MyLibrary' and a test application called 'MyApp'. I do the steps 1-4 above, and below are the contents of the user.config file found at C:Documents and SettingsUser NameLocal SettingsApplication DataMyAppMyApp.vshost.exe_Url_vi5gjcooahbdm2ma3dcay0mkexu2suul1.0.0.0. Note: I did not touch the settings in MyApp;-
<configuration>
<configSections>
<sectionGroup name="userSettings" type="System.Configuration.UserSettingsGroup, System, Version=2.0.0.0, Culture=neutral >
<section name="MyLibrary.My.MySettings" type="System.Configuration.ClientSettingsSection, System, Version=2.0.0.0, Culture=neutral, allowExeDefinition="MachineToLocalUser" requirePermission="false" />

I have two classes in two files in a class library project, they are:
Public Class Logins
Public CurrentUser As Login
Public Function Authenticate(ByVal id As String, ByVal pw As String)

I am going to write a long code in the class library to make the source code shorter for my project. And I willing to store the url strings in the class library, but I do not know how to keep them to be more visible from people who open the dll by using with hex editor. I would like to know in which method that I should use to protected the url strings in the class library and set them more visible so no one would know what url strings that I would store in the class library if people using hex editor?

However, I want to know how can I access Resource file from a Class Library ?
I've created a class library and built a dll (release build). I've then referenced the DLL in another project (I've tried several). I can see the namespace and classes in Object Browser and I can declare instances of the classes but I cannot use or see any of the methods or properties! there is no IntelliSense whatsoever and calling the methods manualy results in a 'Declaration expected' error.
Within the class library solution I have a unit test project referencing the class library project which works all works fine (and all the tests pass).
Can anyone provide any pointers to what might be going wrong here? I've built plenty of dlls in the past and have had no trouble referencing them at all.[code]...
I 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 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".
I have a Visual Basic Class Library project. It generates a DLL. Is there a method to generate a static .LIB to which I can do a static link?Alternatively, can I do a static link against a DLL?
View 6 Repliesmy old vb6 program used to store to ini files now with .net I rekon I need to do something new.. was thinking XML but then in searching around I stumbled apon this my.settings stuff.. so I followed the instructions but something strange is going one..
1. whats the difference between the standard my.settings and adding a new class that is of settings ? anything ?
2. I made 10 new settings in the setting manager but when I try to change then it gives me the old squiggle line saying no go.
I just wondered if you can or can't save arrays using the settings system object. There seems to be no way of entering it at designtime. It seems implied you cannot create new user settings.subobjects at runtime. I'm looking to find the easiest way to save a populated array of PictureBox's. If the only way is a self/custom made/managed .ini file then I need to know so i can start on that but I was hoping to use some of all this phaff in the new frameworks usefully.
View 3 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 got a program where the insert/update SQL was created with the values coded directly into the SQL string. I've changed this to use the Command's Parameters.AddWithValue method and all worked well. I'm now in the process of separating the data access code out into it's own class. I've got the Select code working using a DataSet in the form that I pass ByRef to my data class so it can populate or refresh it. My sticking point is in how to pass the parameters for the Insert/Update commands to the class since from the form I no longer have access to a Command object. Do I need to make the Command object in the data access class available to the form?
View 6 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.
Public Class Class1
Class Circle
Dim rad As Double

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

Can I create my own class library, possibly to be sold commercially, in VB.NET?
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`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.
I want set in class library like this [code]....
View 4 RepliesI 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?
