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 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>

I 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 15 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.

View 2 RepliesIt's been a while since I last posted something, but this attracted my attention. Since many of my programs share the same type of code, I decided to dump it all in a class library for other programs to use.
Now I have a problem, Windows Forms in a class library can't be displayed. There is no "Show(Dialog)" command, only some for event handling. All properties are gone as well. The only way I managed to display a form is by making it as a new variable: 'Dim f as windows.forms.form
But this won't work because of the enormous amount of handlers added to the original.
How can I show my (TextureBrowse in my case) Dialog so other programs can use it?

View 8 RepliesI've an app that starts to work from a module wich should load a form an do other things with a class library who raise an event an the form shoud cath it. The problem is that applicarion.run(frmMain) displays the form in the same thread the the code stops work while the form is open. And I need that the app works in this way because the user need to send files to the app using args and this avoid that the app init another instance of it (in other code) and update the form with the info when the event is raised.

my 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 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".

I have a class library project (.dll) which contains a couple of forms.I now have a new project that would be the Client.

2) How do I set the client to be the MDiParent of the forms that will be opened from the dll?

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).
I just installed VB 2008 Express and started a project.When I saved it, closed it, and re-opened it, my form was GONE! When I try to click on Form1.vb, it's blank.The project still runs properly.

View 12 Repliesthere'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.
