I have coded up a service, and I would like it to monitor when a user logon to the system fails. Is there an event I can handle for this? Or, a message that is broadcast? Or, is it possible to get the failed logon counter for the local system?

I am making "System monitoring Tool" so i have make a GUI and also get the all parameters but one thing missing I have tried to find from different places but not found that is the "continues line" that represents the changing values of CPU usage along time. same like "windows task manager" shows.
View 5 RepliesThis might seem obvious but I was doing some research and I was wondering if a service application start an executable. I know an .exe cannot start without some sort of logon but I was wondering if it was possible to work around this by having my service call it.
View 3 RepliesI'm working on upgrading a solution in VB.NET that is heavily based on Active Directory. As of now, I'm trying to add a PC restriction to a new AD User upon user creation. Essentially, I need to update the Logon To attribute to include 1 or more PCs, how do I go about doing this? I learned that I am interested in the IADsUser property "LoginWorkstations" url...). As of now, I have code that can fetch this attribute from any AD user, but I cannot set it. [code]I've tried testing this approach with a different attribute and it works just fine. Not much out there on Google either unfortunately.

I am wanting to create a logon similar to the Windows Live logon, so in other words. user has frmLogon and is located in Australia. The user enters his/her details and then the program connects to a server in the United States and checks the Username and Password to make sure it is correct if it is correct it allows the user to logon and move to the next stage, if it is wrong it will give him an error message. I am wondering if anyone has a tutorial or source code laying around that I can rip apart and see how it works. I want to put the database on my server and connect to it from my desktop using the logon form.
View 3 RepliesI am currently creating a tool that can manage local user accounts on Windows-PCs. I am using the functions described on
this MSDN page ; and after some struggling, I got most of them to work.
Unluckily, I haven't found a way to set the option "User must change password at next logon" while creating a new user account. I use the
NetUserAdd -Function to create the new user. I set the level to 1 and supply a
USER_INFO_1 -Structure . This structure accepts flags, and the flag UF_PASSWORD_EXPIRED seems to be exactly what I want - but when I set it, the user can log on without changing the password first...
I'm developing on Windows 7 Ultimate 64-Bit using Visual Studio 2010 Express.
Here's my code:
#Region "Constants"
Public Const UF_PASSWORD_EXPIRED As Integer = &H800000
Public Const USER_PRIV_USER As Integer = 1

I have sent print but it never goes inside the loop. There is nothing shows in the Textbox as well. For Each job As PrintSystemJobInfo In jobs.

im trying to make an attendance monitoring system using vb.net 2005. i have a little experienced programming, i used vb6. But vb.net is much more different in vb6 because of its codes. my problem is that in dtpicker, it do not accept any value that came from a textbox.
my code is like this
dtpicker1.value = textbox1.text
but an error existed..then i coded like this hoping that it will work
dtpicker1.value.hour = textbox1.text
I am currently creating an application to track timekeeping (a clock in/out system) and I am trying to work out the best way to do this.
I have a Main Form which contains buttons to ;
- Log in
- Out for Break
- In from Break
- Log out
When a user presses the "log in" button the logon form appears, the user then enters their username and password. What happens next is where I would like the help.
Process is as follows:Click Logon Enter Username/Password Check Logon Form for errors (eg no password etc) Check User is in Database (using SQL query) If user is in DB and username and pass are ok then refer back to the main form to perform Stored Procedure for what the user wants to do (eg logon or or out for break etc). Set label on main form to show user as logged on My question is should I be using a public variable and calling the main form again or in the user logon form having 4 options and using an IF ELSE to select the appropriate Stored Procedure?
I want to create a service that sets up a user specific environment. So I would like to know when a user has logged on to the computer.

View 1 RepliesI am using VB.NET 2008.
On this Windows 7 Professional SP1 machine, when I run the following code in the program
FileCopy(sServer & "loglog.txt", Application.StartupPath & "log.txt")
I got the error "Logon failure: unknown user name or bad password."
sServer is 1 of our server machine.
The Windows 7 machine already logged in to the sServer as administrator, and it also login to the Windows 7 machine as administrator. I run the VB program as Administrator (right click - Run as Administrator).
In the Windows 7 machine I can go to Windows explorer and copy the file manually from the sServer machine to the Application.StartupPath folder.
When my application starts, one of the first thing it does is load a list box with data from an Excel file stored on our server.To prevent an issue I had with two or moreengineers trying to load the data from the same file at the same time, I added code that copied the Excel file to a temporary file (which is,hen, deleted when the data load is done).This has been working fine up until last week. Last week our company moved to a new building.The move included servers and all. Suddenly I'm getting inundatedwith complaints from engineers about my application.It seems that they started getting the following error
View 1 RepliesI created a program with all our clients user name's and password that will be used to log on a web page from our company so i can modify there settings. So far so good i created a form with a combo box to pick a name and then a simple click on the button opens form2 with a browser in it. This browser automatic logs on the page it loads. You should say mission accomplished and we are done........ not yet this stupid page got something nasty in it. If i want to open our clients reports it opens in a new browser and this is something i can't change. So basically what happens if i click the report it opens in the standard user defined browser installed on my machine. This means i get a log in screen again cause my session is in the VB.net browser.
Let me show the code i use at moment that i use to auto log on. For some reasons i did cut out the URL's out of my code. (privacy, security etc.)

View 2 RepliesI get the following error:Application-defined or object-defined error.From what I can understand, it's when I attempt to attach a file to the email, I get that error. What I noticed is that it's because the file is in use.Is there anyway to attach the file anyway? My users are simply not closing their files after saving, right now I'm using computer manager to kick them out. The process is for them to save a file on a server through a share and then I pick that up and send it. Works fine as long as they close the file after save.
View 7 RepliesI have used timers in .Net for a long time now an never had this problem.Start timer to fire every 10 seconds that reads an object and updates the UI using a delegate.This works great until the form is minimized several times, then the timer thread seems to vanish.Anyone come across this before?
Obviously I can roll my own using a thread directly and sleeping it, however this seems like reinventing the wheel when a threading timer class exists already.

I have an desktop application that references several dlls. All are targeted for .Net 3.5, x86. The applicaiton has been deployed for several years and was upgraded from visual studion 2008 to 2010 last year. I have made several changes to the app since then (as recently as last Thursday) with out any issues. Now, everything builds, but when I run the application, I get a type initialiazer error when one of the projects is loaded by the main application.
