Is it possible to get a list of usernames (as shown in Control Panel->Users) on the PC that my app is running on? If so, is it then possible to determine the type of account (i.e. Admin, Standard AND if the account is the Built-in Guest or Built-in Administrator account)?

I want to create a login system that reads the usernames and passwords for a list of arrays:[code]I have managed to code the program so it accepts the correct username and password and sends a error message when they don't match. The problem I'm having is when the user enters a username that isn't on my Username list. The program always crashes when I enter say "admin1000".[code]

View 8 RepliesI have been working on a project in which I need to get all usernames.
Add to form
Public Function GetUserId() As String
Dim lUserName As String
Dim lSuccess As Boolean
[Code].....
Unfortunately, this only gets the username of the user logged on. I was wondering if there is a way to modify this to get all user names.
Here is my code that I wrote its very simple.
Normal Code
If TextBox1.Text = "PleaseHelp" Then
Button1.Enabled = Enabled
End If
BUT I need like multiple correct logins I don't know how I forgot! EXAMPLE: If TextBox1.text = "PleaseHelp, HELP, Thanks" <--- gives me a error I know it isnt the correct way! I just cant figure it out and its basic code....
I am trying to get use to this....I need to know how to type in a database for my usernames and passwords??? I am using visual basic 2008, which I think is visual.net? anyway...heres my code:

Hello.Hide()

View 7 RepliesFirst off, I am a total VB noob. I want to create a program so that I can store usernames and passwords. I want to be able to search by username and pull up their password. What VB program do I need to write this? Can I just use the VB in excel?
View 9 RepliesBasically i am trying to create a programme, which needs to have some authorisation.
When the application starts up, it starts straight into the login screen.
I want the Username and Password textboxes to read the database and if they match then progress to the next form but if they dont match then a message box will appear.
I also want to create groups of people so if a certain group of people log in they go to a certain form and if the another group of people log in i want them to go to a different form.
Also i want the password box to be * instead of visable text.
dbProvider = "PROVIDER=Microsoft.Jet.OLEDB.4.0;"
dbSource = "Data Source = D:/Users.mdb"
con.ConnectionString = dbProvider & dbSource
[Code]....
storing usernames and password after the program closes. I do not want them to be stored in a .txt file, as this is insecure. How do I store it?

When you inputted a username that already existing it will throw an exception, and when you change the username, it still throws the exception.
I am been working on an a small app that has a Forms.Webbrowser control that navigates to a Adobe Flash program. I have developed the app on Vista 32bit platform and have had no problems. I have sent the app to a couple of people to test out and one is using Vista 64bit and is running into a problem. I know the webbrowser control just uses the underlying base framework of IE. The problem on the 64 bit machine is when the site is navigated to it says that it needs to have Flash installed. When the user goes to Adobe's site it says they need to use a 32bit browser.
As stated on Adobe site here:[URL] the Flash player need to be in a 32 bit browser. What options do I have to be able fix this problem? Is there another control that I can use that would be the same in a 32bit platform and 64bit platform? Besides navigating to the Flash program, the browser also goes to standard web pages.
I have the following text that I am trying to parse:
"user1@emailaddy1.com" <user1@emailaddy1.com>, "Jane Doe" <jane.doe@ addyB.org>,
"joe@company.net" <joe@company.net>
I am using the following code to try and split up the string:
Dim groups As GroupCollection
Dim matches As MatchCollection
Dim regexp1 As New Regex("""(.*)"" <(.*)>")
matches = regexp1 .Matches(toNode.InnerText)
For Each match As Match In matches
groups = match.Groups
message.CompanyName = groups(1).Value
message.CompanyEmail = groups(2).Value
Next
But this regular expression is greedy and is grabbing the entire string up to the last quote after "joe@company.net". I'm having a hard time putting together an expression that will group this string into the two groups I'm looking for: Name (in the quotes) and E-Mail (in the angle brackets).
I want to make different levels of access for a vb.net program i'm writing.I have a database called "stratocast". I want to show a specific form for entries in this table with "IsManager" checked and another specific form for those with "IsAdmin" checked.Im using MySql server and visual basic 2010 express
EDIT:To clear up any misconceptions about my post, ill explain further: In my vb.net application i have a login form with two textboxes; One for the username and one for password. I also have three other forms, one is called "frmAdmin", another called "frmManager" and another one called "frmEmployee".
On my database i have a table called "employee" with columns called "name", "title", "IsManager", "IsAdmin", "Username" and "Password".
IsManager and IsAdmin are both Boolean columns
This means that their values can only be 0 or 1 and the result is displayed as a checkbox.When the employee logs into this applcation i want it to check whether or not the employee is a manager, an administrator, or just a regular employee with no additional rights. If the employee is a manager, i want to show "frmManager". If the employee is an Administrator i want to show "frmAdmin". And if the employee has no additional rights then i want to show "frmEmployee".
I'd like to keep the configuration for access level checking confined to the one table but if it's better to have separate tables for each level of access (ie: tables called Admin,Manager, and Employee) then ill consider that too.
I'm actually a beginner in VB express. i made about 10 easy programs, now i decided to make one a bit difficult. I'm stuck at the beginning.In first form i have 2 Textboxes and 1 Button (1username, 1password, button - sign in) and then another 2 Textboxes and 1Button (1username, 1password, button - register) I want to make something like this for beginning: When you register the infos from textboxes (username & password) are saved in some file (let's say in info.txt or info.ini). I actually want to know how to automatically save these usernames and passwords in text file when you click register button, so when you want to login, you have to use registered username&password. So if there in text file is not the username you registered or typed in textbox you can't login.
