View 11 RepliesIs there a built in way to know when a user is done typing into a textbox? (Before hitting tab, Or moving the mouse) I have a database query that occurs on the textchanged event and everything works perfectly. However, I noticed that there is a bit of lag of course because if a user is quickly typing into the textbox the program is busy doing a query for each character. So what I was hoping for was a way to see if the user has finished typing. So if they type "a" and stop then an event fires. However, if they type "all the way" the event fires after the y keyup. Like measuring the time since the last textchange event and if it was > than a certain value then it would proceed to run the rest of my procedures.

View 7 RepliesOK, so, I made a program that locks the computer with a password, to help you protect data from other people. It's quite simple, you open the program, it shows up in full screen, "To access this computer please type in the password"....etc.
BUT, I want it to have a "Guard". To make it act like a screen saver does. That's my plan: So, you typed in the password, and close the program. And then, if you didn't move your mouse, or press a key, or you're not watching a movie, for more than 6 minutes, I want it to automatically launch the program. Until now, I've just put in Form2.Show in the Form1's (which is the password-protect program) FormClosing class. I also made the Form2 on Full Screen, and it's opacity to 0%. That's where you will move your mouse. I made all the code until now, but I need code for making it act like a screen saver.
Can i use the timer when the user tries to log-in and the user entered a wrong password 3 times.i will give the user 5 mins to log-in again with the correct password and if the user enters the wrong pass. 3 times again i will give another 10mins also this is what i want when the user close the program the timer is also their and running that it will give the user the remaining tym on how much tym left 4 him to log-in again.Can i do this in vb.net??i dont know how 2 do this i dont have a clue if it is possible can someone give me a code??

View 1 RepliesI want to disallow changes to two comboboxes unless the user first clicks a LOCK symbol on the screen. I pop a Y or N into the tag of the picture box when they click it...I've got this - combobox is called LanguageTo
Private Sub LanguageTo_Enter(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles LanguageTo.Enter
If Me.languageLock.Tag.ToString = "Y" Then
MessageBox.Show("Click LOCK symbol to allow changes to the Language Pair!", "Language is Locked!", MessageBoxButtons.OK, MessageBoxIcon.Exclamation)
[code]....
How do I "cancel" the attempt to change that combobox?I don't want to ENABLE=FALSE the combobox - as I don't want it's image to visually change. I want to allow them to attempt the change and then abort it if they didn't unlock first.
Here is the final code that worked for me. This uses WNetAddConnection2 to establish a connection first, before using DirectoryEntry.

So I moved the code to an ASP.Net web app, which is impersonating a service account through the Impersonate section of web.config. The account I am impersonating does not have admin rights on any of the workstations so I put in a username/password into the constructor for the computer entry like so:
Dim deComputer As New DirectoryEntry("WinNT://" + Computername + ",computer", username, password).The username is that of a domain account which has local admin rights on every workstation. If I look at the Username property of the resulting deComputer object I can see that the username matches what I entered.Also if I enter in an invalid password it throws an error, so it is authenticating in some fashion.
However if I now try and add or remove a user from a remote workstation I get a general access denied error. If I add the service account that ASP.Net is using as a local admin on that workstation it will add and remove no problem.So next I tried using the LogonAPI (advapi32.dll ->LogonUser call) to login as the user account that is a local admin on all workstations, impersonated the resulting WindowsIdentitiy and tried running just the original deComputer instantiation. When I do this every property, excepty Path, returns an OLE exception..
