If you right click on the time at the lower left of your Windows screen, you can click on "Adjust date/time", and within that, you can update the time on your PC via an internet time server. Is there a way to do the same thing, i.e. synchronize the PC time via an internet server, via a VB.Net program?
View 1 RepliesThis is my first post on this forum, so please excuse me if I'm posting wrong. Anyway, I've been having an issue that I've never seen before and is driving me nut, I have a windows form on which I have placed many textboxes that display information from a MS SQL database. The user can then change these values and hit a "save" button which writes the changes to the database. I also have certain textboxes that with the "on leave" event (after a user enters a possible new value) trigger a method that recalculates some of the other fields based on the new information. Hopefully that all makes sense.
So the problem is, when I run through this "recalc" method the first time around, it doesn't update those textboxes that it's supposed to. However, when I put a breakpoint in and debug through it, the debugger shows it putting in the correct values into the textboxes. It's just as soon as the method is done, it puts them back to blank, or whatever they were before
'Rebind stuff here
lblCabinets.Text = curMfg.ToString("c")
txtCabinets.Text = curMfg.ToString("c")
[code].....
The idea with this form is to add the futures which is calculated when the button is pushed but I need the list to update every time and show the values each time to which the previous value is added to the new calculation, e.g. of what it should look like in listbox:
Year 1: $1,290.93
Year 2: $2,724.32
Year 3: $4,350.76
etc....
I have been working on this a while and I am at a standstill, I was given a function to clear the form everytime it calculates but I don't know how to implement it, I am new to VB. Here is what I have so far:
Public Class frmFutureValue
Private Sub btnCalculate_Click(ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles btnCalculate.Click

I have a button which when pressed, sets the user's rights in the db. (If Administrator UserTypeID is set to '2' and if Customer it is set to '1'). However when I run the below code, everything remains the same. I think it's from the SQL statement but I;m not sure.
Protected Sub btnSetUser_Click(sender As Object, e As System.EventArgs) _
Handles btnSetUser.Click
Dim conn As New OleDbConnection( _[code].......

View 1 RepliesWindows resets the IDLE time every time the user touches the keyboard or the mouse. My application needs to reset the IDLE time at specific moments, but how to do this programmatically.
The following does NOT reset the IDLE time using VB, C# or QT4.
- Programmatic mouse movement / click.
- Programmatic keystroke.
Somehow Windows knows these actions are simulated. How can I reset the IDLE time?
I would like to a) programatically and b) remotely find out the last date/time that a user successfully logged into a Windows machine (via remote desktop or at the console). I would be willing to take any typical windows language (C, C#, VB, batch files, JScript, etc...) but any solution would be nice.

Update tbl_books Set Bk_Rent = Bk_Rent - 1 Bk_Avl = Bk_Avl + 1 Where Bk_Id = ( Select * from tbl_transactions where Trans_Id = @a )
The problem is as far as I know, Update and Select queries have different formats. Update statements will use the ExecuteNonQuery()while Select needs a dataset. My problem is how can I execute these two statements at the same time. I tried this code but it didn't work out.

I need to be able to display 60 * x. X is going to be the time between hitting a Stat button and a Stop button in seconds. I need this to be shown until it is stopped. So i was thinking something like txtBox1.text = 60*time, but I do not know if that is correct and I do not know how to get that time. Also I am not sure how to continuously update the text box.

i just want to update it in the date & time that the record has and i'm thinking that it' may affect the other record's that not on time to update
Before performing an update, the application must search for that record in the database. Once it's found then it return to the Data access layer. Typicaly when i return rows i return them in a dataset. The i send it to the client to load on to the ListView Constrol or to textbooxes. therefore data was sent from the dataset object, therefore onces the user has made updates to the data, first i must update the dataset.
In the Data access layer i can write method that contains the command object for update DB and bind it with the current Dataset so that each time dataset updates it sychrinizes DB with it. Assume i have a method called update() in teh business layer that calls the updateDB in the DataAccess Layer, how can i call the Update() of the business layer each time the user updates the dataset?
I have a very simple StopWatch application in Silverlight. I have the following private properties in my MainPage class: _StopPressed (bool), _TimeStart, _Elapsed (string). I also have a "Start" and "Stop" button. The "Start" button calls a method called UpdateTime that constantly updates _ElapsedTime until _StopPressed is true. When I originally wrote it, UpdateTime would block the UI so I couldn't press the Stop button, so I updated my code to use System.Threading.ThreadPool.QueueUserWorkItem with my UpdateTime method so that it updates _Elapsed on a background thread. That works great at updating the value.However, if I try to set the .Text value of my TextBlock from within UpdateTime(), I get an UnauthorizedAccessException that has to do with one thread accessing the data in another thread.What do I need to do to avoid getting this exception and appropriately update the UI without blocking it?

For example, if I started the program at 4:30:29 PM that is what it will show the whole time the program runs.I need it to constantly be updated as the seconds tick by. So, If I started the program at 4:30:29 PM and ran it for exactly 5 minutes, the time displayed then should be 4:35:29 PM.The data being taken in and saved needs a time associated with it and the end user also need to know the current time as the program is ran in full-screen.

I am trying to figure out an easy way to add custom plugins for the app for additional features, without people having to download a whole new update each time.i guess the way i'd want it to work is,the program will auto detect the plugin file. Then, add's a specific value to either a button array, or add's a picture, etc.Once that button is clicked, it will open a new form designed the way i want it. from within the plugin itself.So its a module.What would be the easiest way to do this?
