Hi,
How does .net framework automatic updates?
Does windows update actually checks/updates .net framework or any .net application actually check any checks/updates?
I have .net application hosted via click once. On certain sites, the application is using lots of bandwidths (I guess it might checks for any updates!).
Thanks,
Divyesh

If configured, Windows Update will do the framework updates for you.

Unless you specifically programmed your application to check for updates this is very unlikely to be the cause of the high bandwidth. Also, as far as I know, the .NET Framework is incapable of checking for updates. Windows itself does the checking.
So any high bandwidth usage in your application is due to the way it has been coded.

Are you talking about the updates of your application, or the .NET updates?
If it's the application, ClickOnce increments version numbers and they can pile up in the ".\ProjectName\publish\Application Files" folder. As the user can only roll-back one level you should make sure only the latest version and the one previous one are in that folder.

I am talking about .net framework updates!
And one question about click once, it shows me one year validity of the license when you publish your application. After one year I think we need to create another certificate. In that case how can we publish new version. Is there any licensing policy with microsoft that can extend the expiry of that certificate?
Thanks,

Hi guys,
I have a problem with autoscrolling of the .NET ScrollableControl. I am using TabPage which inherited from ScrollableControl in the class hierarachy. Every TabPage object has only 1 UserControl derived control which draws the landscape; there is no other control on the tabpage.
The usage of my application is its user will drag a file from windows explorer and drop into the TabPage. As more files are dragged and dropped, the UserControl derived control will expand to accomodate the drawing of the files and auto-scrolling will be enabled.
The problem I have is when I mouse-click on the UserControl control, the vertical and horizontal scrollbars will scroll back to (0,0) position. I want the vertical and horizontal scrollbars to remain at their original scrolled position whatever happens. I believe when I mouse-click on the UserControl control, the UserControl control comes into focus and that triggers the auto-scrolling to (0,0) position.
Please help.
Thanks in advance!

Hi Adam,
Thank you for looking up the link for me! 
It does not help for me: When it briefly scrolls back to the zero position and scrolls back to the original position, I got disoriented where I was in the user-control. I'll look for another solution.
Thanks again!
Have a nice day!

The code below takes a few seconds for each thread/webpage, which is longer than accessing it from an open browser such as google chrome. Is there some setting I need to apply to make it run faster? Should I try to reuse the same webclient in each thread and consider using DownloadAsync? I am thinking that webclient might internally use technology from the slow browser internet explorer instead of google chrome for instance. Is there a public API that would let me download this with google chrome.
System::Net::WebClient client;
client.DownloadString(URL); //URL is a System::String^

That's an unfair comparison; the piece of code will always fetch the page as it is on the server, where Chrome can simply read back it's own cache.
Ted2102 wrote: consider using DownloadAsync?
That wouldn't fetch the page faster, it would only move the task to another thread. You'd still have to wait until that thread receives the entire response.

I recently posted this thread: http://www.codeproject.com/Messages/3498627/How-to-hide-Data-Directory-in-VB-2-0.aspx[^]
something in the reply quite caught my attention: If Ms Word is not running on a database then what would be the best practice for software developers aiming for the sky?
I could easily be classified as a 'master of databases'; I intentionally learnt this over the last 10 years, assuming all along that best software must run on best databases. Is there something i need to learn on how best software are made. this has triggered my thoughts on some two features that did not impress me on vs 2005: that 1) you can't hide/lock access 2003 from users when distributed, and 2) when i use sql 2005, users have to install sql server/express, and the database will be in the server, so sa can easily browse it!!

Wrong. The best software doesn't mean it's using the best database. Not all software uses a database engine.
cyberexel wrote: 1) you can't hide/lock access 2003 from users when distributed
That's Access' fault, not Visual Studio's. The Jet database engine (what Access uses) was not designed to be the top-of-the-line, be all-end all, database engine. It's a simple desktop database geared toward small data requirements.
cyberexel wrote: 2) when i use sql 2005, users have to install sql server/express, and the database will be in the server, so sa can easily browse it!!
Yes, the "sa" account is the "God Rights" account of the SQL Server. It has access to everything, and for a reason.
If your every day users have the password to the "sa" account, that's your fault, not theirs. If you're using the "sa" account from your application in the connection string, that's also your fault. It's your job as the developer to understand the security model of SQL Server and setup users and permissions as appropriate to give those users just the access they need to manipulte the data in the database according to the business rules and nothing more.

Not if it doesn't exist or no one knows the password.

Thanks a lot, Dave.
I have now been actively programming in vb2005 about 3 years now, never really intended to distribute an application until now. (most of my previous applications were done in Access).
1. I am really curious to know how else i will manage my software data if not in a database. Could you please point me to something? I know a little bit of xml but i am not sure what would be a good industry standard. If you dont mind, let me indulge you a little: in my country piracy is the killer for artists and software developers. I want to be able to deliver software that are not easily pirated, and i think getting the database is a very good start for an intending pirate.
2. You mentioned that if they 'dont know the password' an sql database might be safe. my current situation is a client already with sql 2005 installed and they manage sql databases there. how else will they not be able to open mine if it stays in their server? or how do it hide it and still get my connection string right? I dont mind a reading reference...
most appreciated.

(I'm not Dave.)
If it's their database, they can do anything they like with it whether you like it or not.
Your best bet may be to use XML or something and encrypt the file.
Personally, I wouldn't be concerned.

Modern Word-files are usually a zip-file that contains XML and images. Other files might be simple binary dumps of what's in memory (representing code or data).
cyberexel wrote: in my country piracy is the killer for artists and software developers.
..and after the industry wasted millions on stopping it, they still failed.
Most of these companies assumed that a pirated copy is one less sale, which is completely different from reality; if one pirates it, he'll distribute it further to people who wouldn't have bought it in the first place. You're not losing money, but gaining market-share. That's how Windows became a standard in this industry.
There's always the option to have a "free and limited" version and a professional version. If the free version is good enough for the people who wouldn't spend money, then you're still having the same problems (people using your software without you earning from it) - but this time with a positive sound to it

How about writing your data to files?? The format is up to you and your applications requirements.
cyberexel wrote: i think getting the database is a very good start for an intending pirate.
Nothing could be further from the truth. Using a database engine is in no way copy-protection. A database is just a place to store and process data, usually sharing it among instances of one or more applications. Thats it. There is no copy-protection afforded by using a database.
cyberexel wrote: 2. You mentioned that if they 'dont know the password' an sql database might be safe
The DATA may be safe, not the application.
cyberexel wrote: how else will they not be able to open mine if it stays in their server?
You cannot prevent this at all. The SA account, or equivilent, has "God Rights" to everything on that SQL Server.
cyberexel wrote: how do it hide it
You don't.
Look, if copy protection is your big fear, you're wasting your time. The entire software industry has blown billions of dollars on this over the years and still can't prevent unauthorized copying. You have no hope of achieving what they have failed to do.
There are libraries and services out there that will slow down someone cracking your app, but it's inevitable. The only thing you're going to stop is the "casual" home user, who doesn't know anything about computers, from copying your app. But, these libraries and services all cost YOU money to use. Is it really worth it?

Most software that uses a database holds data that is generated by and/or belongs to the person/company using the software. So hiding their data from them is somewhat silly.
If you are that worried about visibility of the database during deployment, then deploy an empty database and put code in your setup routines to generate the tables and data that you need.
Of course I hope you realize that anything you write in .Net can be decompiled using Reflector.

Hi All,
Im developing a app that joins a computer to a domain, but having trouble implementing it using vb.net, any one assist or had the same issue.
Much would be appericatied.
Regards
Dave
Below is the code i have so far to join a computer to a domain :S
Dim args(4) As String
'Dim args2(2) As String
Dim retVal As Long
Dim comp As System.Management.ManagementObject
Dim comps As System.Management.ManagementObjectCollection
Dim clsComps As New System.Management.ManagementClass("Win32_ComputerSystem")
comps = clsComps.GetInstances()
For Each comp In comps
'This is used to unjoin the domain
''args2(0) = "Password"
''args2(1) = "User with privs"
''args2(2) = "0"
''comp.InvokeMethod("UnjoinDomainOrWorkgroup", args2)
'this is used to join the domain
args(0) = txtdomain.text 'Took out our FQDN for this posting
args(1) = "txtpassword.text 'I took the password info out for this posting
args(2) = txtadminaccount 'I changed the admin account info for this posting
args(3) = "ou=Workstations"
args(4) = 1
For x = 0 To 4
'read back each value for debugging
MsgBox(CStr(args(x)))
Next
retVal = comp.InvokeMethod("JoinDomainOrWorkgroup", args)
Next
Return retVal
