‘Remove user and password info before closing Me.Item(“ConnectionString”) = My. & “ user=myuser Password=mypassword” Private Sub MySettings_SettingsLoaded(ByVal sender As Object, ByVal e As ) Handles Me.SettingsLoaded Partial Friend NotInheritable Class MySettings. To refer to the setting in question you use Me.Item(“yoursettingname”) I change it before the app runs and then put it back to what it was before closing.So I use the MySettings_SettingsLoaded event to change it to what I want while the app is running and the MySettings_SettingsSaving to put it back: I would appreciate any help at all, if anybody has any ideas.” Has anybody ever tried this? If I could get this to work, it would make things so much easier. So, the next time the app ran, it showed the old value. But the next day I added more settings this way and discovered it did not store the new value in the. config file, and that it changed in there. It stuck! I thought I had then checked the. When I displayed a MsgBox right after that to show “My.Settings.BaudRate”, it now showed the new value.
When I tested this in my code, I set a new value for My.Settings.BaudRate. And I added a Set block after the Get block. It looks like what is auto-generated in the “” file, except that I removed the “ReadONly” from the “Public ReadOnly Property BaudRate() As Long”.

Within the class, I added code for an application-scoped setting I needed. You decorate that property with the ApplicationScopedSettingAttribute if it is an application-scoped setting…”Īfter reading this, I added some code to the “Settings.vb” file, which is just the skeleton of the “Partial Friend NotInheritable Class MySettings”. You define each setting as a property with both a get and a set defined. In the “Advanced Settings” section of this article it mentions “If you want more control over your settings, you can define your own class that derives from ApplicationSettingsBase, which is the parent class of all settings classes. I found a forum that referenced the following article: I was concerned that maybe it was a permissions thing, but I can open the config file, change the value manually, and save the file just fine.
Of course, when I ran the app again, the old value was still there, not the new one. The setting was actually not saved in the “. When I displayed a MsgBox right after that to show “My.Settings.BaudRate”, it showed the old value. However, it didn’t actually save the config file. ” file) that I wanted to change, and set the default value to the new value. These two code samples worked in that they did locate the specific application setting (within the “. ” (if in debug mode) and change the default value for the specific setting. I tried various solutions (code samples) that were presented out there including a couple that would basically scroll throught the “. However, I would like to make the Application-scoped settings editable, along with many other developers out there. Most of the settings I created have a scope of “Application” rather than “User”, so that these settings values persist regardless of the User. Then I wrote a method, GetConnectionstring, with Database enum parameter.“I am creating a VB.Net application, and created some settings using the Application Settings feature. We can specify all the database names to be used across application and access them using an enum. In this class I declared an enum for the list of the database. You can use this class file in multiple Web applications where you need to use the same database connection. I have created a DBConnectionClass.cs file and then written the following code in this class. Now I will create a common class file with connection code. Now we will see the next way to specify a connection. Using the preceding described way you can connect to the database using this method, there is no need to write a connection code in every page. If you got this error when reading a connection string from a web.config file then go to this link: Click here to fix the following error.
In the following code you can see I have used the GetConnectionstring method of the ConnectionString class and passed the keyname to connect to the specific database using keyname.

Then I will show you how to use the preceding method of this class in code to access connections. In the preceding I have written a method to get the connection on the basis of the keyname passed. public static string Getconnectionstring(string keyname).
