How to create a share programmatically in Vista?

Hi,

I want to create a share on a Vista computer so that everybody has
full access to the share.
How can I do this?

This code only gives everybody the permission to read the share:

using(System.Management.ManagementClass Win32Share = new
ManagementClass("Win32_Share"))
using(System.Management.ManagementBaseObject parameters =
Win32Share.GetMethodParameters("Create"))
{
parameters["Name"] = "ShareName";
parameters["Path"] = "c:\\Temp";
parameters["Type"] = 0;
parameters["Access"] = null;
parameters["Description"] ="Shared programatically from WMI";
parameters["MaximumAllowed"] = 5;

using(System.Management.ManagementBaseObject result =
Win32Share.InvokeMethod("Create", parameters, null))
{
if (((uint)result["ReturnValue"]) == 0)
{
MessageBox.Show("Folder shared");
}
else
{
MessageBox.Show("Folder share failed");
}
}
}

Thank you
Thomas
