DLL Settings - Project That Has Several Different Interfaces ?
Oct 4, 2011
I have a project that has several different interfaces (a website, a local application, and some webservices), that all use the same class library. The library is an API to a database. Some settings, like log level, database connection etc, i want to store in a single place, and I want them editable. What is the best way to accomplish this? I am concerned both about ease of editing, and ease of access for the dll, as there will be a lot of calls to it and a lot of lookups for the values. I have considered using app.config, a standalone XML file, and writing values to the registry, but I cannot find any good comparisons.

is there a way to see the My.Settings of one project from within another project within the same solution?I'm guessing the answer is no, they are scoped at the project level

I have one project that manage my database connection (DBServer) and one project as the main system (MainSystem). In DBServer I store all my connection data that I already managed to my.settings (ServerName, DatabaseName, connectionString, etc). How can I get all the my.settings value in DBServer (ServerName, DatabaseName, connectionString, etc) from MainSystem?

I make project 1. I add 10 settings in the Properties->settings section.
I now make a new project. Project 2. But I want to have the same settings as project 1. It would be easier to import the settings from project1. but can this be done.
Ive seen the setting file in the explorer but this code is auto generated so if its copied into project 2 after you save its regenerated again from the properties->settings values.

I want to add a setting that uses an enum defined in form1.vb. All the research I've done suggests support for enum type settings is built-in and handled automatically by the VS IDE ... I assume this means it's as easy as defining font or color settings. However, I'm not having much. Are any of you gurus aware of how to set up an enum setting via the Project Settings UI?

In a VB.Net project, you can use the Settings tab of the properties page to define application settings. To reference the settings in code, you use the syntax My.Settings.SettingName in VB.
On the Settings tab, you get to choose the Access Modifier. It may be "Friend" or "Public". Presumably, when you choose "Public", you are making the settings accessible to other assemblies. However, once "Public" is chosen, I can't figure out the syntax to reference the settings of one project from another. In fact, I can't observe any difference between using "Internal" vs. "Public" as the access modifier.
My question: Does choosing "Public" as the access modifier make settings accessible to other assemblies? If so, what is the syntax to reference the settings from other assemblies? If not, what does "Public" do?

I get this error
Format of the initialization string does not conform to specification starting at index 34.
When I take my connection string and store it in the project settings. I know that this works.
Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" & Application.StartupPath & "\Employees.accdb
Because if I use it like this
Dim conn As New OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" & Application.StartupPath & "\Employees.accdb")
conn.Open()
The connection succeeds but if I try this
Dim conn As New OleDbConnection(My.Settings.Default.employeeConnection)
conn.Open()
I get that error.
name:employeeConnection
type:string
scope:application
value:Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" & Application.StartupPath & "\Employees.accdb

I like the way one saves settings in VB.Net, that is, with the project properties. However, I want to develop a mobile project that includes saving some settings. Problem is that the project properties doesn't include "Settings" when developing a mobile project.

It must be to close to the weekend, but I thought I read at some time an article of an easy way to have a common settings file for both application and user settings across a solution.
I currently have a Solution that contains 4 projects. Each of these projects need to access the same set of settings and be able to update the user settings. Is there a way to do this utilizing the My.Settings functionality?

I just created a game program out of VBE2008 and did the build process to turn it into a .exe file.When I did the build function I apparently missed the step of attaching an icon to the project.Now when I do a desktop shortcut to the .exe file there is no pretty icon - just an ordinary looking window box.How do I add a desktop shortcut icon to inside the project settings?

I've defined a setting called CustomActions as a System.Collection.Hashtable. I also have a form with two textboxes (Name & CommandLine) that I want to add as a Key/Value pair to the CustomActions settingHowever, when I come to add the kvp to Hashtable I get the dreaded "Object reference not set to an instance of an object". I know what the error means I just don't see why it's relevant here.
Dim CustomActionForm As New DefineCustomAction
If CustomActionForm.ShowDialog = System.Windows.Forms.DialogResult.OK ThenMy.Settings.CustomActions.Add(CustomActionForm.txt_CAName.Text,

For a Vb.net 2008 desktop application that I was just assigned to work on a new workstation, i am getting only the following compile messages:Warning 1 Use command line option '/keyfile' or appropriate project settings instead of 'AssemblyKeyFile'
Error 20 The command "C:racEnroll.app1inDebug\Enroll.app1.exe Debug" exited with code 1. Enroll.ALtot.I know the two lines are related since I have not signed the total application. The file in the 'AssemblyKeyFile' is no longer needed for this application since it is not used. Thus, can you tell me what I can do so the assembly key file is not used? If best, what can I do to get this application tio compile with no errors?

When I open Microsoft Visual Basic 2010 Express, the following message comes up:
Quote: Microsoft Visual Basic 2010 Express. The automatically saved settings file 'visual studio 2010settingsvb expressCurrentSettings.vssettings' cannot be found. You can change this file on the 'Import and Export Settings' Tools Options page. The IDE will use your most recent settings for this session.
I click the 'OK' button, and the Start Page loads with the "Recent Projects" list on the left.
When I click on any of the projects to open them, another message comes up saying:
Quote: Microsoft Visual Basic 2010 Express. "Project Name" could not be opened. Do you want to remove the reference(s) to it from the Recent list(s)?
I read about a potential solution going to "%programfiles%Microsoft Visual Studio 10.0Common7IDE" but I'm not sure how to proceed. Does anyone know why this problem is occuring? Did I truly lose all my projects?

The company has been using Visual Studio 2008 and .NET Framework 2.0 for approximately 2 years. During that time we released several versions (4.x.x) of our program to the public and were able to preserve the user's settings using My.Settings.Upgrade.During the past development cycle we upgraded the program to Visual Studio 2010 and .NET Framework 4.0 and changed the version to 5.x.x. Now, when a user upgrades from 4.x.x to 5.x.x they lose all of their settings.However, in all upgrades after that point (ie 5.0 to 5.1) all the user's settings are once again preserved.I checked C:Documents and Settings<USER_NAME>Local SettingsApplication DataCompanyName and it contains two directories:
ApplicationName_Url_aaa ApplicationName_Url_bbb
where aaa and bbb are 32 character strings. All of the user.config files for the 4.x.x releases can be found in the ApplicationName_ Url_aaa directory. All of the user.config files for the 5.x.x releases can be found in the ApplicationName_Url_bbb directory.Based on this information it seems like something changed when we converted our program to VS2010 and Framework4 that is now causing a different 32 character string to be generated. However, we have been unable to track it down.

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.

I am rewritting my application to conform to ms standards. We used to save all settings to registry for user settings, servername, size and locations.so we are now saving them into My.Settings app.config the only problem is that each time there is an update clickonce will isntall the newupdate but now all settings are loist and user has to save everything all over again..
I am trying to follow the book here but it seems i keep getting stuck somewhere. registry has worked fine for years but i understand we must move on, but if stuff like this happens then i just wasted a long time converting all code to conform for it to not work..

I have the following problem with MEF: Interface definition to be used by host:
Public Interface IExecuteDoSomething
Inherits IAddinSettings
Event DataReceived As EventHandler(Of DataReceivedEventArgs)
Function DoSomething() As Boolean
End Interface
[Code]...
Everything seems to work fine until the Button2_Click routine is executed, then an InvalidCastException is thrown with the info:Unable to cast object of type 'System.Collections.Generic.List1[SharedLibrary.IExecuteDoSomething]' to type 'System.Collections.Generic.List1[SharedLibrary.IAddinSettings]'.
How can i solve this problem, because the imported object implements both of the interfaces?

Im building a game with VB.NET I designed the core of the game in form1 window But now I need menus. How can I implement this without having 5 or so windows that I show() and hide() ? Doing that slows it down a lot and uses lots of memory. I tried tabs, but I don't want the tabs to appear, just switch. Whats the best way to implement multiple interfaces?

What I would like to do is make an abstract class that will hold objects in a dictionary and manage the adding/deleting/key changes of those items in the dictionary. My problem is that in order to make the class as generic as possible I declared the dictionary as dictionary(of long, of SomeInterface).The problem is when I try to pass a strongly typed dictionary in the constructor using dictionary( of long, ClassThatImplementsSomeInterface) I get a compiler error because it cannot convert to that type.
The reason I want to pass the dictionary in the abstract class's constructor is so that I can use the strongly typed dictionary in the subclass and have the abstract class manage the keys when it needs to. So how can I do something like this? Also- If there is a much better way to manage keys than what I am doing feel free to let me know, but I am much more interested in how to make this work since I have encountered this type of problem a few times before.
Here's the abstract class:
Public MustInherit Class HasChildrenKeys
Protected m_childItems As Dictionary(Of Long, IHasKey)
