How to Open Computer Window using VB.Net at windows

To open the Windows "This PC" (formerly "My Computer") window using VB.NET, use the Process.Start method from the System.Diagnostics namespace to launch explorer.exe with the special shell CLSID for the Computer folder.

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

Process.Start("shell:::{20D04FE0-3AEA-1069-A2D8-08002B30309D}")

End Sub

Key Details

• CLSID vs. Shell Command. Both ::{20D04FE0-3AEA-1069-A2D8-08002B30309D} and shell:MyComputerFolder point to the exact same system directory showing your local drives and connected devices.Process.Start("explorer.exe", "::{20D04FE0-3AEA-1069-A2D8-08002B30309D}").

• Opening a Specific Drive. If you want to open a specific drive (like C:\) instead of the main Computer overview, pass the drive letter as the argument: Process.Start("explorer.exe", "C:\").

Thats it!

Types Privilege Level (What the account can do)

Administrator:

• Has complete, unrestricted control over the computer.

• Can install or uninstall software, change core system settings, access all files, and create or delete other user accounts.

Standard User:

• Designed for safe, everyday use.

• Can run installed apps, browse the web, and change personal account settings, but cannot install new software or modify system-wide files without an administrator password (via User Account Control - UAC).

Summary

Standard accounts can use most software and change system settings which dont affect other users or the security of this PC.

Administrators have complete control over the PC. They can change settings and access all of the files and programs stored.

Generate random value between minimum and upperbound in VB.NET

To generate a random value between a lowerBound and an upperBound, use the standard scaling formula: random() * (upperBound - lowerBound) + lowerBound for decimal numbers, or floor(random() * (upperBound - lowerBound + 1)) + lowerBound for inclusive integers. Most programming languages and spreadsheet tools also provide built-in functions to do this directly.

VB.NET

' Initialize the random-number generator. Randomize() ' Generate random value between 1 and 8. Dim value As Integer = CInt(Int((8 * Rnd()) + 1))

messagebox.show(value.tostring())

The Rnd function returns a value less than 1, but greater than or equal to zero. Before calling Rnd, use the Randomize statement without an argument to initialize the random

-number generator with a seed based on the system timer.
