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 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).
how am i going to check if the directory that was inputted in the textbox is a correct directory?
View 2 Replieseverything in the code works except for 1, in line txtTotal.Text = (Val(txtHomeTax.Text) + Val(txtLandTax.Text)) is where i think I'm having troubles. it shows 0 everytime, I use val but it still shows 0. but if I remove the val, it will show both numbers together

I have a form that allows users to enter information into a few textboxes. When users click save, the information will be transferred into the datagridview.
My problem now is, for instance, there is a textbox called "Price" with the datatype "money" which users are only allowed to enter numbers. If users enter alphabets, errors will occur. I don't wanna use try catch, I would like to try different methods such stopping users from entering anything into the textbox when the datatype isn't correct - nothing will appear in the textbox when users hit all the keys in the keyboard except for numbers.
Using this
TxtBox = New TextBox()
With TxtBox
.Name = "T" & reader("area").ToString
.Visible = True
[code]....
The name would come out like "T3" Now I want to put a value into that textbox.How can I address the correct Textbox?
I 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.
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)?

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

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 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.

That code works to read the entry data and to recognise the correct data, and the incorrect. However, even if entry is correct, the error msgbox will appear (x times of how many records there are in file), despite being navigated to the menu. Anyway that the Else isn't triggered when data is correct. Also for it to appear just one instead of (x times of how many records there are in file.)
I have created a basic query generator which allows a user to select the Select, WHERE and criteria attributes using a number of checkboxes.However i have got stuck. In the results form i have the following code
Private Sub DisplayRecord()
RichTextBox1.Text = ds.Tables("newResults").Rows(intCurrentRecord).Item(0)
RichTextBox2.Text = ds.Tables("newResults").Rows(intCurrentRecord).Item(1)
RichTextBox3.Text = ds.Tables("newResults").Rows(intCurrentRecord).Item(2)
[code]....
The program keeps on crashing if the user does not select the corresponding amount of display records from above for the amount of attributes they want for the SELECT part of the query in the intreface in form 1.
How would i go about making something where the number of SELECT attributes selected which are listed in a string create the correct number of textbox fields in the results form (form2)
I think this will be better than what I was thinking before.
