Verify If The Users (Username + Passowrd) Is Correct?
Jun 26, 2010
Ive googled and found only "GetElementById" which is not what im looking for. Also this is for logging in to a site through a vb .net form only.
I just want it to verify if the users (Username + Passowrd) is correct and telling me some how if its correct or not.
Ive got permission from the respected owner here how the link to connect looks like [URL]
Also i have to do this through "http get request" + "Winsocks" i think.

When I originally set up my project I 'hard-coded' my username and password in so that I could access a remote DB2 database. Now that I need to publish it to other users they need to be prompted for their own usernames and passwords. I've gone to "My Project/Settings" and deleted the items from the string - but when I run I get the following message on the statement:
Me.BATCHTableAdapter.Fill(Me.DB1DataSet.BATCH)
ERROR [08001] [IBM] SQL30082N Security processing failed with reason "3" ("PASSWORD MISSING"). SQLSTATE=08001
The settings are as follows (before I delete the userid and password):
Name:DB1ConnectionString
Type:(Connection string)
Scope:Application
Value:Database=DB1;Server=99.999.999.99:446;userid=myuser;password=mypassword;Persist Security Info=True;
The question is what do I have to do to make it forget my userid and password - and always prompt the user for both when running up?

how do I do this properly:
vb
Imports System.IO
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
[code]....
I would like to store some app data in a 'default system folder', so when I launch the program it will know where to look for it's own settings.As a matter of fact I only need to store there a path to the files used by the program. Users will be able to choose where to put them (simplified installation). The program has to know where to look for them.
Am I creating the folder properly? As you can see I'm referring to C:... The folder structure presented here comes from my laptop running on Windows 7 Ultimate. Maybe the C:... can be somehow defined by some sort of a system 'shortcut'. Following the above example the program would look for those in C:... , but maybe I can use something like ~~ default.app.settings.My Program Name ~~~. How does it work? Have no idea how to call it properly, but I'm sure you will know what I mean.

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.

I'm a newbie in visual basic. I'm doing a login system. I'm done with the GUI. but for the programming part, I want to know where to store new user's information along with the username and password. I've done research. seems like it has something to do with database. p/s: I'm looking for high security in storing data to prevent hacking.

I've created code that generates a random number and validates the users guess to see if its correct. I think the code is good but i'm not 100% sure. I need to add additional pieces to the code and i'm not sure where or how to do it. allow the user 10 guesses. after 10 guesses disable the ability to make more guesses if the 10th guess is wrong count each guess entered & display the count as it increments display each guess along with its returned messaeg into a list box. when the user gets correct answer provide a box to allow them to play again. Re-initialize variables back to their starting status.
a. If the user correctly guesses the number in less than 5 guesses display "Either you know the secret or you got lucky!" in a message box. b. If the user correctly guesses the number in 5, 6, or 7 guesses, display "Ah Ha! Do you know the secret?" in a message box. c. If the number of guesses is 8 to 10, then display "Try to do better next time." d. If the number of guesses exceeds 10, then display "You have taken too many guesses."

I have an asp.net web app that uses forms-based authentication, a SqlMembershipProvider (using an encrypted password format), and a SqlRoleProvider. I need to know if it's possible to administer the users (create new users, assign them to roles, etc.) from a windows application - the powers that be don't want any administrative functionality in the web app itself.Here is the membership provider definition from web.config:
<membership defaultProvider="MyProvider">

1.I�d like to publish a free vb.net desktop application for the users to download and use meanwhile I�d like to collect usage information ex: user ip address, user�s registration information, used features, time spent� if the user allows the report to be sent back.
2.Also , in order for the user to be able to use the application, he�ll have to register it then, everytime, before the application loads, it gets verified online that it was registered, maybe validate the registration information or a valid user name and password, no critical personal information. The target of this step is for the application to be used exclusively by the registered user and maybe on his computer only.

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've created a little procedure that I use to verify if a value does actually exist. I'm currently using this all throughout my application for things such as verifying if a control's EditValue actually has a value. I was wondering if I have missed any scenarios where a value would not be available, missing, non-existent, blank, etc., and how would I incorporate in my procedure.
Public Function ValueExist(ByRef CheckValue As Object) As Boolean
Try
ValueExist = True
If IsDBNull(CheckValue) Then
ValueExist = False

I have not been able to successfully verify a user with LDAP for an ASP.NET web application. I have done so on our own network against Active Directory, but this is against a server outside of our network that is OID (Oracle Internet Directory).Usually, I use the following code with no problem.
Dim myDirectoryEntry As New System.DirectoryServices.DirectoryEntry("LDAP://1.2.3.4:999/OU=SomeOU,DC=Something,DC=com")
myDirectoryEntry.AuthenticationType = System.DirectoryServices.AuthenticationTypes.Sealing
myDirectoryEntry.AuthenticationType = System.DirectoryServices.AuthenticationTypes.Secure
Try

After that, I haven't been able to find a method to verify a user's log in information with their password and then pull back some information.
