Exit The Form Without Entering The Correct Password?
May 16, 2010
I'm trying to make a secondary security system to use on my computer. I made a form with a password field in the middle, the size of the form cover the entire screen and there is no border. But now I'm trying to find a way to remove all possible ways to exit the form without enter the correct password like CTRL+ALT+Del, ALT+F4, CTRL+ESC, CTRL+TAB, WIN KEY, or any of the short keys. I'm using Windows Vista Ultimate and everything I've found is for 98 and XP and won't seem to work. So in other-words I want it to be impossible to exit the form without entering the correct password.
I have created an application which asks the user to enter password to login.Now how can i inform the user(if his caps button is on) that his caps button is on while he is entering his password?
Was wondering how to make it so users can log into the program and this would be much easier since the program allready connects to a database to add a username and password table which i have,how can i get it so when i click a button the program will check with the username specified if its in the data base and check the password of the given username returning a yes value if its right and conuing or exiting if its wrong?
i want to make a program which lock the computer screen until user enter the correct Password what will i have to make this application and how i can do this
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 was wondering if someone can point me in the right direction.I want to be able to have the user type information into specific fields on the form and when they select print, it auto generates a pre made form and just fills in the areas that they type in.
If I have a form that has these fields: Name:______ Address:______
I have beginner skills using VB (am using the Express edition to learn). I would like to know how to set up a conditional statement in a Windows Form (WF) app that would check if a specific command line has been passed by another separate app that launchesthe Windows Form app using command lines, and if not passed, then the Windows Form app would shut down (exit, close).So far, I can use:
For Each s As String In My.Application.CommandLineArgs If s <> "xyz" Then Me.Close()
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.)
On each of my form I have put an 'Exit' button. When user clicks it, another form is displayed (I don't want to use 'MessageBox') asking user whether he really wants to quit. If user clicks yes the form closes. If user clicks no, form is redisplayed.
However, out of 4 forms only one form refuses to redisplay. The code is exactly same on all forms. I have included 2 Express 2008 projects showing one form each in the zip file apps-ssk.zip
What i want to do is not allow the entering of the same thing in the same field that has already be used. eg. field(entry) 1 is already in the database. So when trying to enter 1 and field(entry) anymore it will give error msg and make change before saving.
i am using validated function and i would like to close the form without entering any input and not generate an error. is there a method that changes the exit command to allow this?Sometimes the answer is so blindingly obvious i fail to see it.
I'm having a bit of a problem getting my application to close properly. Basically I have one main form from which all other forms open. If a user tries to close that main form, I want to bring up a MessageBox asking if they want to exit the application.However, when I try to do that it asks the question twice. It seems that the Application.Exit() is triggering the FormClosing event again for some reason, but I don't know of another way to exit the application. BTW, the main form isn't the startup form so I can't use the option to close when the startup form closes.
i'm using exit sub when a certain condition does not meet. but the problem is that the form closes. it should not close the form, instead, it should only exit from a click event. I'm using VB2008Express Edition and MS Access at the back end.[code]
Now I have a sub to validate a bunch of textboxes and combo boxes.I previously used many IF statements to validate and pop up different messageboxes and Exit Sub in every IF statement.But I heard that too many Exits will decrease the efficiency and they were not recommended to use. Instead, nested IF is better because it will let the process naturally go to the end.Then I found out that if I use nested IF,it will be hard to read, since messageboxes are all separated from conditions.
I have a MDIcontainer form witch handles MDIchildren. The problem I'm having is when i open a new Mdi child and close the Main form , The app is supposed to ask if i want to save the current MdiChild. Heres my code
How to exit a form using escape button in vb.net 2005. I need to show a msg box with yes or no conditions only.... Now I am using this code for exit a form.. If e.KeyCode = Keys.Escape Then Application.ExitThread() End If
I want to create a simple program and I'm trying to do this with run-time design.with this form, when you click on the button1 with the caption(Text) "Show Another Form", another form will be created with this code:
Public Class Form1 Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click[code]....
How can I exit the form I've created when you click on the Cancel Button. The code I've provided doesn't work.
I have a Setup form that calls the main form after the user clicks on a button. This works fine in VB6, but in VB.Net, the original form either hangs around if I call the new form with .ShowDialog() or the new form exits immediately if I call the new form with .Show()...
I have created an application which has a parent form and various child forms, when all child forms are closed and only the parent form is viewable would it be possible to exit the application?[code]...
The form opens a simple form to accept a password if a name is selected from a dropdown. The form is opened modally from the validating event. If I select an item, fill in the password, close the modal form , it will not let the parent form close depending on how I exit the dropdown. When I look at the closing event cancel is set to true implying that the control still thinks it needs vaidating.
It works if i leave the dropdown cell in focus when I hit close.
If I click (even just once so the dropdown still is highlighted but just closed) on another cell in the grid the form will not close. It corrects itself if I repeats the first method.
Even worse if I press enter twice it crashes without going through any of my code when the grid tries to do its own commit edit on the editableControl but seems to have a wrong reference as it tries to use the DataGridViewComboBox as the editablecontrol and gets a cannot cast exception
Updated as I have found the cause.
The pop up password form is a home brewed modal form by disabling all open forms but leaves some menu items active.(mdi is used). It is the disable form that causes the issue. Without that it always works. So it seems the grid cant handle being disabled while changing cells.
A solution that works is to use ShowDialog but that changes the systems behaviour so I may not be allowed to do that.
When a user clicks on the little red "x" a.k.a. the form close button on the form command bar, what even is activated besides FormClosed()
I know FormClosing() is called, but I cannot really stop the form from closing after my code is run. I want to be able to show a messagebox that asks if the user wants to exit the form or not. Obviously if they click no, I want the form to stay open, how would I do this?
I would like to know if there is a way to save the text property of a label or any object when i exit the form. For example, if i type in "hello world" in a text box and exit the program, i want "hello world" to become the new text property of that text box when i exit.
