I try to call the function HidD_GetHidGuid from hid.dll, but it gives me an error, can someone explain y thanks
my piece of code is :
public partial class Form1 : Form{
[
DllImport("hid.dll")] private static extern void HidD_GetHidGuid(Guid GUID); public Form1(){
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e){
Guid HidGuid = new Guid();HidD_GetHidGuid(HidGuid);
textBox1.Text = HidGuid.ToString();
}
}
the error (when i click the button) is :
Attempted to read or write protected memory. This is often an indication that other memory is corrupt.

The Guid you pass in must be a ref parameter. How else would the function be able to modify it
