问题
I'm trying to make an Operating System in Visual Basic (program based of course) and it needs personalisation.
I want the user to be able to choose from a select group of images, stored in the Resources of the project, and I want that image to be saved, so that the next time they log on to the software, the form has the same image they selected saved.
Extra Information:
The image selection is on a seperate form. Using:
If ComboBox1.Text = "Beach Fade" Then
PictureBox1.BackgroundImage = My.Resources.beach_fade
End If
Main Desktop form uses the "Background image" to have the image selected.
回答1:
Use My.Settings to persist user settings.
This is the code I used to demo it. I have a form with ComboBox1 and PictureBox1. With this code, you can have your image selection persist.
Go into your project properties and click the Settings option on the left. Create a setting called BackgroundImageName of type String. You can choose if the scope is saved per-user or per-application.
Then in project properties go to Resources and add two images named "beach_fade" and "mountain_fade". You know how to do this
Then paste this code
Public Class Form1
Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
Me.ComboBox1.Items.Add("Beach Fade")
Me.ComboBox1.Items.Add("Mountain Fade")
Me.ComboBox1.Text = My.Settings.BackgroundImageName
setBackgroundImage()
End Sub
Private Sub Form1_FormClosed(sender As Object, e As FormClosedEventArgs) Handles Me.FormClosed
My.Settings.BackgroundImageName = Me.ComboBox1.Text
End Sub
Private Sub ComboBox1_SelectedIndexChanged(sender As Object, e As EventArgs) Handles ComboBox1.SelectedIndexChanged
setBackgroundImage()
End Sub
Private Sub setBackgroundImage()
If ComboBox1.Text = "Beach Fade" Then
PictureBox1.BackgroundImage = My.Resources.beach_fade
ElseIf ComboBox1.Text = "Mountain Fade" Then
PictureBox1.BackgroundImage = My.Resources.mountain_fade
End If
End Sub
End Class
The application will start up every time with the image selected in the ComboBox before last close.
