Hi everyone!!

I am working for in a school project and I need to put in disable my mouse and keyboard, I read a lot of blogs but I found the same solution, the problem is that it doesn't work

//declare this
using System.Runtime.InteropServices;

[return: MarshalAs(UnmanagedType.Bool)]
[DllImport("user32.dll", CharSet = CharSet.Auto, ExactSpelling = true)]
public static extern void BlockInput([In, MarshalAs(UnmanagedType.Bool)]bool fBlockIt);


private void button1_Click(object sender, EventArgs e)
{
    BlockInput(true);

}


I have a windows 7 laptop, a Microsoft visual studio 2008

Thanks!!!

Try this which has answer How can I block keyboard and mouse input in C#?[^]

I recommend this article for you - Processing Global Mouse and Keyboard Hooks in C#[^]
   
C#
[System.Runtime.InteropServices.DllImportAttribute("user32.dll", EntryPoint = "BlockInput")]
     [return: System.Runtime.InteropServices.MarshalAsAttribute(System.Runtime.InteropServices.UnmanagedType.Bool)]
     public static extern bool BlockInput([System.Runtime.InteropServices.MarshalAsAttribute(System.Runtime.InteropServices.UnmanagedType.Bool)] bool fBlockIt);
