VS 2010 : Close And Open A Form - Make A Login For A Program?
Jul 16, 2010
How do I Close a Form and then open a new one straight away? Im trying to make a Login for a Program, but I want the Login Box to open first, then disappear when the credentials are correct and a new Form to load.
I am having a difficulty in this login form that I have made. The same as the premade template login in VB 2008 which I am using right now.Here's what happens when I run the program Log in form open > Log in successful > Main window appears *The login form still does not disappear.
I tried hiding it via me.hide() Log in form open > log in successful > Main window appears > log in form disappear.*Now the problem is that I cant close the whole application because the login form is still there only hidden. Again I tried putting in the "EXIT" button the code me.close() login.close()Log in form open > log in successful > Main window appears > log in form disappears > Exit application *Now everything seems to be ok now and then I found another problem.Instead of clicking the exit button I tried clicking the X button on the main window. There I found out that it only closes the main window. Therefore not closing the whole application because the login form is still hidden.
I am developing client-Server Application, when Server send a command i want to open the form1 and close the form2, Client side has two forms and one class.when i recive the message from server,this code(written in class) execute but it cannot do anything.
I have this button to open one form, and close the current form. When i click the button, the opened form closes and the program closes. In the button code, i open the one form, and in the one form's FormLoad is to close the first form.
I want to make a login system for my program, and i want it to pull the list from an ftp as an text document. (Lets say its ftp.notarealftpsite.lol)
The text document will be arranged like this:
user:pass ipwn:not ilolz:yet
and i want the program to search for the provided username and password in the list and switch to form2 if its found, else it will throw an error at the user.
I have a vb.net form which has a button in it. The button will call A.exe (it's a vb.net exe) using the command Shell("A.exe ", AppWinStyle.NormalFocus).

I have a login form and after a successful login, i open another MDI form, but i want to close the login form. I have given the code as:

Similarly, is is possible to open the login form on an inactive MDI form [MDI and Login for to be seen] and when th user login details are correct, it must close the login form and return to the MDI Form.

I have a problem about shown event. I have a login form and a main form. I start the program with main form. then I used frmMain.Shown() to control the login form. When main form is shown, it checks Win. Registry if username and password is stored there. İf yes, login form comes and wants me to sign in and if not, it calls first login form to create a record in Registry.The problem is that; When I click on X (close) button, it closes the login form, but Main form is still running and I can use it without sign in. How do I solve this problem? Or is there any other way to controls if Registry has the record or not

Is it possible to issue a Open CD and a Close CD using VB.net? Are there any examples of code I could see or articles? Thanks for you help, in what seems to be such a trivial matter. (I know though that the simpler the function the more code seems to be
Dim IncomingCommand As String = e.CommandLine.Item(0).ToString
If IncomingCommand.Substring(0, 2) = "-1" Then
form1.close()
End If
End If
I am trying to make the program close if the -1 string is sent with the program. See my installer allows for me to run certain programs before it actually installs, but it doesn't shut down copies of the program itself. So I have a next startup instance set to shut the program down if the -1 is received. But if the program is not running it starts up instead. This is not desired. form1.close doesn't work. e.cancel = true doesn't work, etc etc. What can I do to make the program not start during this instance.
I never had problems with this before but now this ain't working right. What I want to do is open a new Form and close the Current Form that is already open. This code use to work for me
