i have a login form in a banking project.i set a userid and password for this login form and i did the code accordingly,it works good.In my form there are two fields namely:Userid and Password and a button named Login.
But i cant get any idea about what to do when the user wants to create their own userid and password?
I think i need to add a few more buttons to enable the user to create their own userid and password but i cant get the idea......i need some help.
Again,if i allow the user to create their own userid and password then anyone can use my project by creating a new account.........
Hence i am totally confused how to go with this.I need some urgent discussion so that i can get through this problem.
The error is raised after a normal user changed his password on - Windows Server 2008 Standard server joined to a workgroup

View 9 RepliesI'm trying to write a console application that can modify registry subkeys on remote pc's in the same network. I have it working in my own environment but when I install on the customer machines I'm getting unauthorized access when it hits the OpenRemoteBaseKey. The security settings in the application properties is set to full trust application so I'm not sure why it won't work.
I'm using Visual Studio 2010 and first I just installed it on the customer machine and when it wouldn't work I ran the source code in Visual Studio 2005 which is on the customer machine but got same results.I can run the app directly on the remote machine and it will change the registry subkeys as directed, I just can't do it remotely. RemoteRegistry service is started. Both machines are logged in as administrators.
Here is the source code:

View 4 RepliesI'm trying to create a password change form for my company's vendors. There are a couple of scenarios I could encounter doing this:
1 - User enters invalid current password
2 - New passwords do not match
3 - User's account is locked
4 - User cannot authenticate because password is expired
It's case 4 that I'm struggling with, because their is no way for me to take the password the user entered and verify it against active directory without getting an error.

I put together a small app I want to use on my local network for service monitoring across a few of my servers.
I'm using vb.net express 2010 with system.serviceprocess imported The problem I am having is that my code only seems to work locally, and will not retrieve the service data for any server on my network.
For example, my local machine is called "office-pc", and when running the app on it, I get all the service information.
Dim localServices As ServiceController() = ServiceController.GetServices("office-pc")
For Each localservice As ServiceController In localServices
ComboBox1.Items.Add(localservice.DisplayName)
Next
But, if I want the service info from my web server called "casper", I use the same code, but i change the GetServices() parameter like so;
Dim localServices As ServiceController() = ServiceController.GetServices("casper")
For Each localservice As ServiceController In localServices
ComboBox2.Items.Add(localservice.DisplayName)
Next
After a few seconds delay, nothing happens, ComboBox2 remains empty.
It was my understanding that GetServices() would get the local machines service info unless a machine name was specified, which in both cases is true.
So why isn't it working? Do I need to set something up on the network servers first?

I have to admit that I was sceptical it would work... but below is the code. I had to make a minor change to the code you suggested. Whenever I tried IPC$ it would return a 53 result code, even though I'm sure the share exists. So at the suggestion of another website I removed the share and just the computer name and this worked.
