Save One Of Custom Types To The Application Settings?
Mar 9, 2011
(using VB.Net 2008) I am trying to save one of my custom types to the application settings. I've read a variety of opinions on the internet about whether this possible.
When creating an app setting, none of my types appear when browsing. However, previously I needed to save off one of my datasets, and it worked simply by hand-entering it as the setting type (ie, I just typed "MyProjectName.DatasetName"). However, when I try the same trick with another custom type that isn't a dataset, I get a "type was not found" error. So I'm a little confused, can the program "find" some custom types and not others?

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 have created a user setting named 'setmeup' as string, scope = user, value = "magical meow meow!".in my code i access it and assign it a new value like this...my.settings.setmeup = "howdy cowboy!"my.settings.save()application.restart()when the application restarts, i expect the my.settings.setmeup = "howdy cowboy!" but when i check its contents its still "magical meow meow!".but when i use application.exit() instead of application.restart() and manually restart the program, my.settings.setmeup = "howdy cowboy!" which is correct.what must i do? i want to use application.restart() because i don't want the users to double-click the icon again to start the program. i want the program to restart automatically.

I want to save a Custom DateTimePicker.Value in my Application Settings. The custom format is : dd/MM/yyyy hh:mm:ss, instead of dd/MM/yyyy The field i've created in the application settings parameters is LASTSAVE (DATE / APPLICATION)
When I try to link in the ApplicationSettings/PropertyBinding ... VALUE with my field LASTSAVE, i have an error :
The Value '01/01/0001 00:00:00' is not valid for 'Value'. 'Value' mustbe ... 'MinDate' et 'MaxDate'.
Name of the parameter : Value
I then entered the MIN and MAX date in the properties of my control DATETIMEPICKER.
I have also put into the properties Value a start date like 23/11/2011 12:00:00 ;
However, when i retry to link in the ApplicationSettings/PropertyBinding ... value to LASTSAVE / I have the same error (The Value '01/01/0001 00:00:00' is not valid for 'Value'. ). I've saved all, do a process that put a value in the datetimepicker.value, but it's not saved, cause not linked.

I'm trying to save a collection of key/value settings in my application's "user settings" (they're column widths), but while I see no errors, when I run the code (in the IDE) my collection in "My.Settings" is always nothing at startup. I do a "My.Settings.Save" when the application exits, and barring the "serializers not found" errors in the IDE, no other errors occur. When I run my application as an exe, it behaves the same way..

I am starting to use cryptostream class. I may be wrong, if you encrypt something, close the app, and then try to decrypt it, it will not be able to because a different key will be generated. Because I do need this functionality, I am wondering if it's possible to save the key in application settings and whether this is the right way to go?

How do I save my settings in the same folder of my application is in .INI file.[code]And how do I delete the app.config folder in the AppData Local dir?Because what I noticed is.. It creates new folders everytime I release a new version of my application.It doesn't consume much space though but still it creates new folder corresponding to the application version.

In Delphi you can do something like this :
TArray = array[1..3] of byte;
where you can then declare
T2Array = array[1..3] of TArray

Is there a way to maintain application modified Settings in the settings files after a program update? i.e. I have 10 or so values in the settings file and the users can modify them... when I send a program update they revert back to what I initially programmed them to be.

I'm studying for the MCTS exam 70-536 and have come across the following question:Given the following Visual Basic code sample, which interface must the custom class MyClass implement?
Dim a As MyClass, b As Boolean
a = 42
' Convert using ToBoolean.
b = Convert.ToBoolean(a)
Console.WriteLine("a = {0}, b = {1}", a.ToString, b.ToString)
Before even looking at the possible answers, I can't get past WHY on earth would we be converting the number 42 to a Boolean value?? I tried this and as I suspected it did NOT compile! Is this a trick question or am I missing something? I realized that in order for the code to work, I would need to implement one of the interfaces shown in the multiple choices. STILL, would there EVER be a purpose for this particular conversion?

I am calling a XML web service (standard web service project based on .NET 3.5) and trying to pass custom types as parameters. The custom types are defined in my consuming code and the web service references an assembly from the consuming code to get access to the types. The serialization is being handled by .NET.
<WebMethod()> _
Public Function MyMethod() As MyType
Dim myValue as new MyType
return myValue
End Function
In my consuming code I created a web reference to the service and the proxy classes were created. I gave the service the namespace "WebService". Next I try to make a call to the service and assign the result from the call to a variable, something like this:
Dim service As New WebService.ServiceNameSoapClient
Dim response As New MyType
response = service.MyMethod()
I get an error from the IDE saying that it cannot convert type mynamespace.WebService.MyType to mynamespace.Entities.MyType. It appears to me that although the types are similar they are being treated as different because of the different namespaces, which makes sense of course.
Edit: So from what I am reading I believe this is by design, that is the proxy types are simply different types and cannot be directly associated with the types in the consuming code.

I've been following this article:and have everything working.Under the Support for Custom Types section, it introduces a collapsable type for the spell check options. The option are added together to produce a string that is displayed in the grid in the Spell Check Options row. Is it possible to get this string directly from the 'AppSettings' class or do I need to add another property and copy the code from the ConvertTo and ConvertFrom functions?

I set up some application settings for checkboxes on an app and then decided to remove them. When I set the Application Settings to (none) in the designer and restarted the app, the checkbox constantly checks and unchecks itself. I completely remade the app and removed the file that is used to store my.settings in the Local folder of the user's appdata profile. I also made sure to uncheck the "save my.settings" on shutdown.

I have a Visual Basic .Net 2.0 program. I'm moving the settings from an older settings file, to an app.config program settings file. I'm trying to do this as nicely as possible.
So, I added my setting as shown in this image.
On load I do this:
If My.Settings.databaseConnectionSettings Is Nothing Then
My.Settings.databaseConnectionSettings = New ArrayList()
End If
[Code]....
So, the question is, how do I get that arraylist of my DatabaseConnectionSettings saved to persistent storage? I want to do this in the cleanest way possible. That is, I don't want to have to convert it to a string or save it to a separate file every-time I want to use it. I would like to be able to use the My.Settings accessor method.

In Visual Studio 2005 or 2008, when adding any User Controls to a Windows Form or other User Control in a Project that implements and is using a custom settings provider, a "Failed to create component" error is displayed. If all references to the custom settings provider are removed from settings.settings and that file is saved then User Controls can be added to Windows Forms and User Controls. However, if the custom settings provider is referenced again in settings.settings, then opening the designer of a Form/Control which includes a User Control results in a "One or more errors encountered while loading the designer..." error message.
I have had a very difficult time in tracking down the root cause of this issue because I assumed it had to do with my code and not the IDE. I am working within the context of a large project which uses User Controls heavily and have written a custom settings provider to persist user settings to a SQL Express database. This settings provider works properly, however if I want to open any Forms or User Controls in designer view I must first manually remove all references to my custom settings provider in setting.settings and then re-add them after the changes are done which is inconvenient to say the least. This problem is not present if the Project is in C#.

I was just wondering what is the Quickest way to set up custom settings, every software has settings that are created and saved, Example a Hotel Software has rooms, roomtypes etc that are used in combination with other things, an Accounting software has Account type, Employee Software will have Full time,Parttime, or anything else, An Employee time Clock would have departments, Tax Brackets.

I would like to be able to specify exactly where the My.Settings file gets saved. It bugs me how it gets saved off in the middle of appsettings nowhere, and I would prefer it gets saved where the executable is. If anyone knows how to do this, that would be great. (P.S; I'm using VB.Net.)
