Passing Password At Runtime?
Feb 6, 2012
I inserted a bindingsource and then created dataset and tableadapter through it. In my connectionstring, did not select to include sensitive data to it (password)
Now when the application runs, it says Invalid Password and crashes. Off course it is what we expect. Now my question is, I want my application to load password that I have passed in a variable e.g. vrMyPWD as string="abc123" before it loads
Me.TblInvoicesTableAdapter.Fill(Me.DbInvoicesDataSet.tblInvoices)
at from_load. So there is no error and application works normally.

I'm writing a windows service in VB.Net and set the service process installer's "Account" property set to "User". So when I tried to install the utility using INSTALLUTIL.EXE it is prompting to enter the user id and password. So I wanted to suppress this "Set Service Logon" so added below code to ProjectInstaller.vb and I was able to do what ever I want: [code]

I have very new to VB. I was just fiddling and ran into this. I cant set the text alignment of a text box twice with the focus events as well as cant set or reset the password char property. The code is given below:
Private Sub tbxLogin_LostFocus(ByVal sender As Object, ByVal e As System.EventArgs) Handles tbxLogin.LostFocus
If tbxLogin.Text = String.Empty Then
'tbxLogin.ResetText()
tbxLogin.ForeColor = Color.Gray
'tbxLogin.TextAlign = HorizontalAlignment.Center
'trying to align the tbx gives it focus

I'm trying to create a password change form for my company's vendors. There are a couple of scenarios I could encounter doing this:
1 - User enters invalid current password
2 - New passwords do not match
3 - User's account is locked
4 - User cannot authenticate because password is expired
It's case 4 that I'm struggling with, because their is no way for me to take the password the user entered and verify it against active directory without getting an error.

I am implementing a system where the user can Reset their password if they have forgotten it.Once it is reset I want to give them the option of changing the password so that it will be something more memorable to them.The password is hashed and if i enter in the correct old password and new password the password does change.If I enter in the wrong old password and new password the password doesnt change.Is there a way to match the old password with the old password field in code behind so I can throw up an error to the user to tell them what is wrong?

How do you get a textbox being using for password entry to display the black circle that you often see in web forms, on the iphone etc etc?
I can change the PasswordChar property to an asterisk no problem and even copying and pasting symbols inserted into Word seemed to work - just couldn't find a symbol that looked like a bullet point!
Can this actually be achieved for a standalone exe, or is it something unique to web forms? Surely copying and pasting symbols from Word isn't actually the answer?

I'm making a custom control suited for handling passwords. I have created a control that inherits from a text box and I have implemented a lot of things so far. But what i want to do now is create a system so that when a user types It will display his last character typed for a X amount of time.Is there a way to turn only selected characters into password characters and still be able to get the password text from the Text property ?

I'm creating an app to manage the movies I've watched and get some info about these movies and then display these info in labels.At moment I'm trying to load the "runtime" and "genre" into label3 (runtime) and label5 (genre). Once the movie name is clicked in the listbox control, these info are loaded from a website (webbrowser control) and then displayed in the labels. My question is: Is there any way to make the My.Settings save these info for EACH movie? Something like this:
Saving the info:
vb
If ListBox1.SelectedItem.ToString > 0 Then 'LOADING THE INFO CODE... 'SAVING... 'create: My.Settings.(ListBox1.SelectedItem.ToString & "1") = Label3.text 'create: My.Settings.(ListBox1.SelectedItem.ToString & "2") = Label5.textEnd If

In VB.NET, can we pass an original object as an argument without instantiating it? For example, I have two forms in my project formA and formB. Now I have this code.
[Code]...
Apart from this, in VB.NET in any class like formA, if I type formA, I can see all the objects and controls present there but not in C#. Again, I have to make a new instance to see all the controls. This becomes a problem if I want to manipulate two running and working instances with each other. So what basic thing am I missing here?(I am an amateur programmer migrating from VB.NET to C#. Things are going nice and clean expect for the ones I've recently figured out.)

I am trying to pass a 2D array into a dll I wrote in C. When I run the program, it crashes at the first line (in the dll) that I try to read the array. It gives an error that it is trying to read protected memory. I'm guessing this means the array was not correctly passed to the dll, so the program is trying to read a memory location that doesn't exist. Is the problem somewhere in my VB code? If not, it must be in my C code, right?
Here is my VB code:
Declaration of the function in the dll:
Code:
Private Declare Function image_processing Lib "image_processingDLL.dll" _
(ByRef image_array As Long, ByVal dpi As Long, _
ByVal xDim As Long, ByVal yDim As Long) As result
Calling the function:
Code:
Call image_processing(hImgArray(0, 0), hImage.HorizontalResolution, _
hFilmPictureBox.Width, hFilmPictureBox.Height)
