Multi-User

I have made a Visual Basic OS with Multiple User sign in but can not figure out how to give them difderent desktops and programs,

Many Thanks,
Thomas

Create a system of multiple folders with user's files such as Documents, Pictures, Music, etc. and also some files containing strings that your OS can read and transform them in settings, e.g.: there's for every user the file "colorskin.txt" that contains the word "red", the system must read that file and if is written "red" the displayed color is red, or if is written "blue" the displayed color is blue, etc. Make this system also for other settings (such as Browser's home page, Username, Password, or whatever you want).

Im tackling the same issue, im using custom files to house the info and used a parse command to sift through the material

Listboxes and custom text files can do the trick

I use this approach:
upon registration:
- the software creates a folder for each user with this syntax: userID+role+password (e.g.: alexa001sky)
- a series of subfolders are created: documents, received files, customization, media

upon login:
- the software checks if a folder that contains userID and password exists. In this case, it splits the string to get the role (e.g.: a001)
- it loads from the subfolders all the settings
- loads the role into a system variable called 'permissions'.
- depending on the role it hides the applications a certain role must not access

Neat. We have also developing something similar and a similar for an admin to do it remotely both are going well. Our system simply utilizes folders available on the system but we may implement a similar folder system. Our only issue is that if you browse for something. How can you contain it in a folder set and not the whole pc? Anyone know?

Yes there is a simple procedure where you define an InitialDirectory that contains the base path which the user is authorized in. Then, on every program that needs browsing, you check if the opened folder starts with thinitial directory.
This is an example for a RTF word processor to save a rtf file:


Dim dlg As New SaveFileDialog, fName As String = String.Empty

Do

With dlg

.Title = "Save File"

.Filter = "Rich text files (*.rtf)|*.rtf"

.AddExtension = True

.DefaultExt = "rtf"

.InitialDirectory = “c:OSrootuserID+role+password”   'you decide what the OSroot is

If .ShowDialog = Windows.Forms.DialogResult.OK Then

If Not .FileName.StartsWith(.InitialDirectory) Then

MessageBox.Show("You cannot change the target destination", "Warning!", MessageBoxButtons.OK, MessageBoxIcon.Warning)

Else

fName = .FileName

RichTextBox1.SaveFile(fName, RichTextBoxStreamType.RichText)

Exit Do

End If

Else

Exit Sub

End If
Loop


The same procedure can be used on opening files.

Oh yeah.lol i forget about initial directory.lol

I just came up with a more elaborate method, but we just figured out how to create multiple accounts and delete them/edit them, and change accounts as well as set account permissions. Now we are working on a server version for business use (ie. Remote configuration to client pc)

When you create a user profile system thats so robust and complicated you cant remember how it works.lol
