Is there any way to determine that a system has automatic updates enabled and has the little yellow security center icon indicating that updates are available? I'd like to drop a little service on one of my servers to monitor for that condition but can't find a good resource to get started.
View 12 RepliesI was wondering if there is a way to detect if Windows Updates are currently being installed.The reason is that I have written some software that sends my PC to hibernation if is idle for a specific amount of time, but I do not want this to happen if Windows is in the process of updating.
View 2 RepliesI have an application that starts from Sub Main and I need to run a sub when the system is about to shut down, restart or logoff so it can save it's settings. I found some code on google:
Imports Microsoft.Win32
Public Sub Main
AddHandler SystemEvents.SessionEnding, AddressOf OnShuttingdown
[Code]....
But it doesn't seem to work, Windows shuts down yes but when I re-start the vm and run the app it opens with the old settings, not the ones that I changed before I shut down the vm. Anyone know of a way to do this or to fix the code above, I don't think my OnShuttingdown event is being handled.
Currently converting the infamous Windows Update VB Script examples to VB .NET so that I can have a more polished GUI for our end user's as we have to nofity them every step of the way when installing updates (so the built in WUA interaction is not viable for us).
Converting from VBS to VB .NET seems to be more troublesome then I estimated, FYI I am no a full time .NET programmer so I might be making newbie mistakes!!!
So here is the VB Script example from MSDN for searhing, downloading and installing Windows updates using VBS:
[Code]...
I am writing a Windows Update Client in preperation for it's use with our Windows 7 OS when we start to migrate this year from our Windows XP SP3 computers. We currently use a vbScript to control the installation of Windows Updates, we dont use the built in Windows Update client for the installation of updates as we need a little bit more control to allow for the deferral of updates being installed and more notification to the end user as to when a reboot will occur.
I want to replace the vbScript with a VB .NET executable as the presentation of information is much nicer, so I took to converting the Microsoft WUA API examples from vbScript to .NET, Following is the the vbScript Example code I am working with, at this stage of development of the application I am looking just to get a count of updates that need to be installed:
Set updateSession = CreateObject("Microsoft.Update.Session")
Set updateSearcher = updateSession.CreateupdateSearcher()
WScript.Echo "Searching for updates..." & vbCRLF
[code]....
This is going to sound weird but I was wondering if there is a way to show in a list all of the installed Windows Updates.
View 9 RepliesI'm trying to figure out if specific Windows updates are installed so I can install the correct ones.I'm currently checking the WindowsUpdates.log file that is located within the windows directory, but it's terribly unreliable.In my search to find an alternative method, I cam across this blog post. It seems like a perfect fit. Unless you take into account that this is VBScript and their querying Microsoft.Update.Session.what class in WMI that would relate to VB so I can pull the info.
View 4 RepliesIve only recently starting fiddling with Visual Basic Express and Sql Databases. Ive managed to get a database up and running, and can query information from it. I have even created a form that can add a new entry to the table im using.The first form has a ComboBox that list the PlayerNames in my table. Form2 allows you to add a new name to the table, but anything I add isnt immediately updated in Form1. I have to relaunch the program to see the new entries. Even then, these new entries dont seem to be permanent as they eventually dissappear.The code I have for Form1:
Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
.................0......................................................

While working on some functions that update my database, I was writing some quick tests just to make sure my functions were executing properly. When it comes time to actually update the database I can pass a transaction to a function and then commit it:
user.Assignment("assignment value for some column in table", connection, transaction)
transaction.Commit()
I am curious if there is a way to write a quick test that can verify that the transaction will actually update certain rows before committing?
(pseudoish-code)
user.Assignment("assignment value for some column in table", connection, transaction)
If Not transaction["SomeColumn"] = "Expected value for SomeColumn"
assert("ColumnName was not going to be updated to the expected value!")
transaction.Rollback()
I'm using LinqToSql to talk to my database. It's working great but I would like to know if there are pending changes. I know how to endedit() and submitchanges() on the underlying context. But is there a property that will tell me if changes have been made? I've looked through the properties and methods of both the bindingsource object and the datacontext but nothing is popping out at me.

My code simply runs procedure at SQL Server and copy data into excel. Excel is then saved, closed and released from memory. After that I have added code for Cells alignemnt and Cells formatting and problem raised again and excel is again pending in running processes. 4 rows of sheet alignemnt causes that, and when I comment them, then its ok again. Same when I used formatting by .NumberFormat.

what's the best way to handle the updates to the database.For example i have one datagridview that's binded to a datatable (with two fields, id auto incremented and a varchar). The user can do all the operations Insert, Update, Delete.If i insert one row (only the text) and call the update method to save the changes to the database, and after that remove the same row and call the update method the adapter will throw a exception because it didn't update the datatable with the value of the id. So the best way to do this is always calling the fill method after every update?
View 22 Replieshere is part of the code i am working with at the moment:
Public Sub runbar(ByVal time As Integer)
sleep(2)
Dim i As Integer
i = 0
ProgressBar1.Maximum = time
[Code]...
The problem is that when i click the button to run this, it does the runbar animation BEFORE it updates the text box. I have even tried putting a loop around the TextBox1.Text = obj to see if that would force it to work, but it did not. I would like to know if there is anyway to get the text to update before the runbar animation runs, just seams weird as i have the text editing first lol.
Last night 3 updates automatically installed from VS 2008 on my comp KB952241, KB971091 and KB973674 Today intellisence was not working for .net - I uninstalled the updates and everything is, once again, working fine I dont know what update did it ... But I was just wondering if anyone else has experienced this - I would rather not have the updates if they stuff things up.
Oh - and before anyone asks - I tried resetting the visual studio settings
I would like to ask if it is possible to do a multiple records editing by linqtosql method in one click event? What I've been trying to do is to edit all the names in the table which are having the same account number. I was able to edit but only one name has been edited and the rest are not
******************************************************
Private Sub Button2_Click(------------) Handles Button2.Click
Dim accnt As String
accnt = Textbox1.Text
[Code]....
Why is it these codes could only edit records in one datarow? Can you debug the codes to edit all records which are having the same account number after it is being query?if that is possible for you.
i am making a software =D (Does the Name matter ??)
Ohk so its gonna be my first try
my last soft was a success with 800+ downloads
so i want my program to check for updates everytime it opens or like when it clicks on a button
then it checks if there are updates then it will show the link to download the new exe file in a messsage box or in a textbox
I have code similar to the code below that works in other parts of my program. The reason the code below does not work is because the datatable is made up of data from two separate tables. Does anyone know how to make this work for multiple tables? Can I choose what fields to send back and where to send them? This is what fills my datagridview and it works fine.

i dont know anything about any of them XD
1). Whats a server? are they web based or locally on a pc?
2). I've made a program and want to make updates for it and put them on the web for download, Do i need a server to do this?
3). How do i make updates work on visual basic 2008, i mean ive made a program and i want to put it on the internet but i also want to bring out updates, apparently i can use visual basic to automatically download updates and install them. What do i need to do this? where can the updates be downloaded from on the internet? will a file share like rapidshare work?
I am using WM_QUERYENDSESSION to detect Windows shutting down in my vb.net app, but the complexity is that I need to quickly load a console application during this code to do some cleanup. It is looking like the console
application is not even loading, even though I can cause delays in the vb.net code. Is there a way to do this?
I know you can do it with an WMI event or overriding WndProc and looking for the right messages, but i was wondering if there wasn't something hidden in the net framework that makes this task easyer.

I know the default install path of the app and the name of the .exe file, but is there a way to see if it is actually installed? I've seen suggestions for checking registry entries, but I don't know if this app uses any or if if varies for different users on different pc's.

Is there for my .Net application to detect if a user has logged on? It is a Windows Service, so it will be running before logon.What I want to do is display a "popup" when a user logs on to tell them the status of the application

View 2 RepliesI need to produce an error display message when the Windows Mobile PDA is in flight mode. The user will need to pull and push data from a SQL Server server; however when in flight mode this is not doable and a message needs to be displayed. Currently the message that is displayed is:
A request to send information the the computer using IIS has failed. For more results please see HRESULT.
I am programming using VB.Net and I am fairly new to it. I have searched for the past week on the Internet and come across information suggesting that I use TAPI, however I do not know what to import, or where the "flight mode detection" code would go in my application.
I am very new to vb.net. I need to be able to see when a certain popup window appears in another application. The time time it takes to appear varies so I need to know when it appears and in some cases when it has closed.
