store logged in user id in database from class file

Hello all,

I am storing the user id for a record who creates it. It is working fine in aspx.cs file.

myReview.Owner = (Guid)Membership.GetUser().ProviderUserKey;

but when I use the same code in a class file in App_Code folder then it does not work and code breaks.

Is there any other way to get user id in case of class file?

Please help me I am stuck on it for a long time.

Many thanks...

Try this.

use Context.user instead of Membership.GetUser() .

Try this.

HI Shelly,

I did not get any reference to Context.User

However I used HttpContext.Current.User.Identity.Name).ProviderUserKey;

but it is also not working...

Re: store logged in user id in database from class file

Membership.GetUser() is returning the surrently logged in User.

HttpContext.Current.User.Identity.Name is returning the Username of the currently logged in user

So try Membership.GetUser(HttpContext.Current.User.Identity.Name).ProviderUserKey

Re: store logged in user id in database from class file

Hi Hans,

it is also not working. Object reference not set to an instance of an object. error message is displayed. when I debugged the code and copied the details then it gives the following message.

System.NullReferenceException was unhandled by user code
Message=Object reference not set to an instance of an object.

Re: store logged in user id in database from class file

Is HttpContext.Current.User.Identity.Name actually returning what you are expecting? Can you give much more detail on how you are doing this (for example, are you using AspNetMembershipProvider?). Maybe you can go through this walkthrough and let us know if you have issues:

Re: store logged in user id in database from class file

HI I am trying to upload images using httphandler.

for this I have few settings in web.config as below.

in aspx page I am having a control to upload files, which in turn transfers the control to the Upload.cs class in App_code folder, where code is as follows (I am logged in at the time of uploading files)

public class Upload : IHttpHandler, IRequiresSessionState
{
public Upload()
{

}

#region IHttpHandler Members

public bool IsReusable
{
get { return true; }
}

public void ProcessRequest(HttpContext context)
{
using (ProjectEntities myEntities = new ProjectEntities())
{
MyFile myFile;
string virtualFolder = "~/Images/";
//string uploadPath = context.Server.MapPath(context.Request.ApplicationPath + virtualFolder);
string uploadPath = context.Server.MapPath(virtualFolder);
// loop through all the uploaded files
for(int j = 0; j < context.Request.Files.Count; j++)
{
// get the current file
HttpPostedFile uploadFile = context.Request.Files[j];
// if there was a file uploded
if (uploadFile.ContentLength > 0)
{

string fileName = Guid.NewGuid().ToString();

string extension = Path.GetExtension(uploadFile.FileName);

myFile = new MyFile();
myFile.Name = uploadFile.FileName;
myFile.Url = virtualFolder + fileName + extension;
myFile.Owner = (Guid)Membership.GetUser().ProviderUserKey;

//myFile.Owner = (Guid)Membership.GetUser(HttpContext.Current.User.Identity.Name).ProviderUserKey;
myEntities.AddToMyFile(myFile);
myEntities.SaveChanges();

uploadFile.SaveAs(Path.Combine(uploadPath, fileName + extension));}

}

}
}

}

The code breaks at when storing logged in user's id. Please help me.

Thanks

Please guys help me, I am struggling with this error for a long time. Kindly suggest some solution Thanks

Re: store logged in user id in database from class file

Can you verify that you are getting this value? Just have a page that does Response.Write(HttpContext.Current.User.Identity.Name);

My best guess is that you don't have a value there - you are maybe using Anonymous authentication? You could also just add a good username in the web.config to see if it gets past the error:

Re: store logged in user id in database from class file

HI cts,

yes I was not getting the username there (I don't know why) but later I passed the userid directly through querystring, and then it is working.

If you can point out why it was not getting username in initial code then it would be very helpful for me to point out the mistake.

Many thanks

Re: store logged in user id in database from class file

Perhaps you were using Anonymous Authentication? The HttpContext will be the process identity unless you are impersonating - in which case it will use the IIS authenticated user by default. So, if you were using anonymous authentication and impersonating, you would likely have nothing for your httpContext identity.

See ASP.NET Impersonation for more details.
