.net - Load Up Combo Box Values Once (at Login Screen)?
Mar 10, 2011
I have a few combo boxes that need to be loaded up once and displayed multiple times (whenever the main form is opened) The reason for this is because it's taking about 10 seconds for the form to load each time it's opened due to unnecessary re-querying.
Here is an example of what I have as a combo box source and what I've done.
I've put the query, connection, etc... in a module and call it on the login form - i don't get any errors but the data does not load into the combos.
'In Module
sql = "SELECT DIR_ID, DIR_NM FROM LTC_FBS_DIR ORDER BY DIR_NM ASC"
RConStr = String.Format(RConStrFormat, LoginForm.txtUser.Text,

I'm coding a splash screen in VB.Net that displays for 3 seconds then shows a login screen. But the splash shows up even when login shows and I have told the splash to hide. Here is my code:
I've got some code like the following. I want it so that when I chose an item in 'select 1' it changes the in the second combo box but I'm not sure of the best way to go about it. Does it have to be AJax or can it be done with just Javascript?

I want a rich text box to display public variables like (pizza toppings links etc that have been selected in other forms) these variables have declare in a module. But I want the rich text box to display these variables as soon as the screen loads ( a on form load event) if you know what I mean.
Basically what my problem is, is that i've got a login screen set up where a user can select their username from it, but it's only displaying one name, rather than the 2 i've got listed in my SQL dataset.Also, how would i go around checking that the password matches the username?
I am trying to make it so when a user logs in the code can tell, if they are a user or not, if they are a user, then if they are a teacher or not. I have SQL in there to identify if the person is a user or not, but it won't bring up an error message if they aren't. And if both the users logging in are not teachers they are still able to view a screen they are not meant to.
I am writing a simple password self service app that allows users to change their password and unlock their accounts. My last step is to figure out how to get it on the login screen. Basically so users can run it before logging in (necessary because this is to help if their passwod is lost or account disabled). I've seen screenshots of commercial apps putting it on this screen and/or the actual login box (like in XP) but I cant find any information on how to do this.

I would like to create my own custom login screen for windows xp, so instead of typing my password, just put my finger on a fingerprinter sensor and my app will read the fingerprint and see how it is, then make the login itself.
We are running XP workstations in an Active Directory domain. I used gpedit.msc to setup a startup script that launchs Spy++. This works, and just before the login screen comes up, Spy++ pops up. The only problem is, the Spy++ window then goes away just before the login window loads.
I want to use Spy++ to find the attributes of the XP (Active Directory) login window. Is there a way to do this?

I have a combo box on few of my vb.net 2010 programs. The end users that use my program have touch screens and they have a hard time making selections on the combo box. I have an Android cell phone and when ever there is a combo box it will open another screen and making the selection is a breeze.
I would like to create a login screen with username/password. The login screen should validate username/password before the user is redirected to the next screen.
I need to create a login page as part of an assignment. Problem is, I don't have access and I'm not sure which other programs can be used as alternatives. I am hoping that it's possible to create the login screen using only a If...Then...Else Statement. If it is possible, I'm probably going about it the wrong way, as it skips the first two conditions and goes straight to the 'Else'.

I've created a windows form application in vb 2010. I've got all my forms complete and now want to add a Login screen. One the login screen, after the username/password is entered and OK is pressed, I try to open the a connection string. Obviously if the connection fails, the user has entered the incorrect credentials. If the credentials are ok, True is returned and I then open up the Main form that shows the correct items for the logged in user.

I am trying to create a log in screen for my program using data from an access database. I am trying to load the data from the database so that I can use it to check if a username and password combination is valid.
I am working on a program that is rapidly growing. After the login screen, I have to wait about 10 seconds before the main form shows up. I want to add a loading or splash screen in that time, but I am having a lot of trouble having two forms launch at once.

After running the following code (which locks the computer), what code must I be applying to see if the user has successfully logged into the computer and that "Lock Screen" I'd so called has disappeared?
Private Declare Function LockWorkStation Lib "user32.dll" () As Long Private Function LockComputer() LockWorkStation() End Function
I will call "LockComputer", after that what do I do to see if the Lock screen so called by this function (after say 2 minutes) has disappeared or is still there asking for the password from the user.
