Replace The Logon Screen?
Jan 24, 2010
I was thinking about replacing my log on screen. I don't just mean changing the background style or whatever, I mean a totally different app, which would allow users to log on and off. I'm prepared to spend a serious amount of time on this, and I just wanted to know if it is concievably possible, and if anyone's ever done it before? I want to do this because I'm sick of the Vista log on screen. This doesn't neccesarily have to be made in vb, I could de-compile the .dll files which make up the logon screen and then re compile them.

I'm using Windows 7 Pro (32bit) and have .NET 3.5 and 4 installed.I have written a .NET screensaver and have enabled it to run on the Windows logon screen.[code]BUT when I'm logged in the screensaver works.So it isn't a faulty installation of the .NET framework, or else it wouldn't work fullstop.

I am planning on creating a service that measures the bootup time for a computer. It would go something like this:
1. Service starts and waits for CTRL+ALT+DEL screen
2. Timer starts when logon screen appears
3. User logs in and timer stops
4. Service waits for process X to start
5. Process X starts and service gets System.Environment.TickCount
6. Service subtracts step 3 ticks from tickcount
The reason for the logon screen timer is I don't want to measure if the user booted up and went for coffee or something and shows up 20 mins later to log in. Is there any way for the service to detect when the logon screen is present and when it's gone?

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.

BTW this issue occurs in any MS office program when the VB.Net (or even VBA) is processing information.Example: In Excel, a worksheet is displayed on the screen. I start either, a VB.Net or VBA procedure and within 30 seconds the Excel worksheet (previously displayed) blanks out. In both VB.Net and VBA,ScreenUpdating = False. My expectation is that the previously displayed screen would stay static as if I left my desk to get a cup of coffee; came back and the same ole Excel worksheet was still there?Of course, setting VBA Screen Updating = False accomplishes two goals: 1) speeds up processing and 2) saves the user from seeing unnecessary "garbage-processing" steps.Why does VBA or VB.Net ScreenUpdating = False not freeze the screen at the time of its invoking?

The file reads in parameters and two of the parameters used to be in Date Format YYYYMMDD but will now permanently be in format YYYY-MM-DD. This change, I believe, is stopping the import of the file from working. I would like to replace the new format YYYY-MM-DD back to YYYYMMDD in the code. If possible I'd also like to see some output so I know that the old format has been replaced with the new format. The code is below. I added the two rows with .replace code in green in expecting that to be enough but it is still not working.
Public
Sub Main()
Dim R1, O1, P1, C1, strDateFrom, strDateTo, strRunDate

I'm working on a timekeeping application in Visual Basic 2008 and am having trouble formatting a timespan for display. Here's how I want to the information:If a positive number my Label will be: lblTimespan.txt will show as "12 Hours And 15 Minutes" This works fine.If its a negative number I want to display it as "(12 Hours And 15 Minutes)'[ in red. The problem is that I can't get rid of the minus sign. [code] Thr Replace doesn't seem to want to replace the "-", can anyone suggest what to do?

I have a bunch of object variables which are all initialised in their declarations such that:
Private _myObject As New ThisObject("SomeString")
where ThisObject is one of a number of object types, but all are initialised using a string.
I would like to use the Visual Studio Find/Replace dialog box to search for "As New" then replace everything from "As New" to the first set of speech marks with some text such that:
EDIT
My original example could be solved using other methods. This example is more representative of the actual problem:
Private _myObjectA As New ThisObjectA("SomeString")
Private _myObjectLongName As New ThisObjectLongName("SomeString")

I am trying to think of a regex replace to replace double quotes with nothing. Example:
hello("hi there") would become hello(hi there)
"hi" would become hi
"example "3" would become example "3
-edit Maybe an easier way to explain this is, replace all " that do not have a backslash before them.

I did a quick google search however all I could find are tutorials that make the form and database in the same project which localizes the database.. I want to put the database on my server and connect to it from my desktop using the logon form..

This 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.

I'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 need to logon to a NAS Drive to query directory listings. All users will be logging into a domain. The NAS also has security set up on it with a different username password.
I will have a handful of users (maybe 10 - each logging into the same domain, but from different pc's) that will need to access a NAS Drive to query a directory structure. All will have physical access, and can connect via windows explorer (manually entering a user and pass).
During my first attempt via my app - I get the error "Logon failure: unknown user name or bad password" Which is good cause I only want a handful of users logging on to this drive. If I logon to the drive via Windows Explorer and then go back to the app and it works.
So what I did was create a multi form app.
- At launch the parent form loads (as well as a logon window within that form). The logon window auto fills a text box with a username. That is pulled from the current logged on user - or can be replaced. I would like each user to then enter a password -> send that to the NAS for authentication -> then either open the app (mentioned above) or give some kind of a message box saying they now have connectivity to the drive.

I am trying to filter out all unwanted characters from a string. All I want in the string is letters A-Z, numbers 0-9 as well as comma (,) plus (+) and quotes (").I figured how to do the letters and numbers, but the 3 special characters are giving me a problem. I also tried with the Chr(34) equivelant for the " sign, but no luck, as and " or , messes up the way the code is read. Here�s what I have so far, but it only works for A-Z and 0-9:
STR = System.Text.RegularExpressions.Regex.Replace(STR, "[^A-Z, 0-9, Chr(43) ]", "")

I have some code which queries the AD for a users information. On Windows 7 this works as expected but on XP it returns the error: Logon failure: unknown user name or bad password
This seems to be across the board on XP machines, except the development was done on XP and tested on a different XP machine and they were fine. I don't have access to these 2 machines anymore so I can't test to see if it still works on them. don't know if it is a problem because of XP or a different reason but all I know is it doesn't work and XP seems to be the common denominator.
The error is thrown at this line:
Dim entry As DirectoryEntry = New DirectoryEntry("LDAP://ldapString", "username", "password")
As I say, this works on 7 but not on XP, it also works when logging in through ADExplorer. What could possibly be the problem?

Hi guys, we have an application which requires elevation to admin rights on VISTA/Windows 7 machine because it provides an ActiveX interface. We can't at present get around this requirement. With a manifest file and on a VISTA machine we get the UAC administrator prompt 'An unidentified program wants access to your computer' and logon request. Disabling UAC is not an option with our clients. I believe that authenticode signing the EXE will at least make the program trusted and thus remove the logon request. But I believe we will still be left with a grey prompt that asks something like 'Did you run this program, do you want to continue' - is this correct? Is there any way of getting rid of the prompts completely?

Is there a way to programmaticly get the failed logon count for local Windows users in XP and later? Alternatively, is there a way for my service to get a message when a failed logon occurs? Currently coding in VB.NET, but will take any suggestions in any language.
