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 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 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.
View 6 RepliesI'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..

Does anyone know of a good way to save settings in vb.net?
The only way I know how to do right now is to make a registry key with a specified value and call upon it when the program loads up again.
I can't do this though because I have a whole lot of data I have to save.
can you save the data in a notepad and call it line by line to save each feature?
It's just a login form that is supposed to save your connection settings, but it won't save my values; they revert to the previous values every time I run the program. Does the IDE just not save your settings, or am I doing something wrong?

It saves the settings to the registry, loads the preset settings, and if you want to uninstall the app, you can use the delete settings, which deletes the registry folder for you app.
Here's how:
create a form, 1 textbox, 2 check boxes, 3 buttons named as (setbtn, getbtn, delbtn)
'1 textbox, 2 check boxes, 3 buttons as setbtn, getbtn, delbtn

Public Class Form1

Apparently the system.collection.arraylist does not work since it is more of a list than anything else. Is there some sort of collection that will save my array as is so that it can be retained latter on application load?
View 5 RepliesI use a textbox AutoCompleteCustomSource to save recent entries within a textbox and obviously, then autocomplete them when the user enters a matching value. When the application is closed then re-opened these values are lost.
I believe I can save the values using My.Settings but I haven't been able to get it to work.
I created a setting 'AutoCompleteList' of type System.Windows.Forms.AutoCompleteStringCollection in the Project properties > Settings area.[code]...
What I am trying to do is serialize an object map and store it in My.Settings. There appears to be no data type that can be used in My.Settings that would hold a byte array other than a string. Therefore, I encoded the byte array from the serialization and turned it into an ASCII string, but it wasn't a true representation of the bytes, and the deserialization failed. Converting the bytes to an ASCII string apparently chops some of the bytes down to 7 bits, which hoses the conversion.
Before I get into anything too bizarre, I figured I might as well put the question here: Is there a way to stuff a byte array into My.Settings?
