Use UUIDGEN or GUIDGEN to generate your own guid.

00000000-0000-0000-0000-000000000000
Null guid is just a placeholder.

the following vb.net code will generate a random guid:

Dim myGuid As Guid = Guid.NewGuid()

Hi scm0sml
Result of below code is
MY GUID = 1088729d-124d-4d0e-b5f3-d9ac36d787bb

Result of next code is
MY GUID = e7bb3880-9594-48a3-bf13-818c7c60d079

Harry
    protected void Page_Load(object sender, EventArgs e)
    {
        Guid _myGUID = new Guid("1088729d-124d-4d0e-b5f3-d9ac36d787bb");
        Response.Write("MY GUID = " + _myGUID.ToString());
        
        Guid _myGUID = Guid.NewGuid();
        Response.Write("MY GUID = " + _myGUID.ToString());
 
    }

Open in new window

i didnt want to generate a new guid i juyst wanted to be able to view it as it wasnt showing up in code as anything other than the place holder.

harwantgrewals answer did the trick:
Guid _myGUID = new Guid("1088729d-124d-4d0e-b5f3-d9ac36d787bb"); replacing the guid with a string variable
