And on top of what Simulation said, if you copied the code to a file share and are running the code from that share, you need to take into consideration Code Access Security. Managed code running from ANY non-local source (i.e.: network) runs in a restricted sandbox. If I understand your explaination correctly, this is probably where your "Security Exception" is comming from.
Bascially, the users machine doesn't trust your code. You have to tell it to trust the code. Read[^].

I'm trying to make windows local users with VB. This is no problem. I'm stuck trying to set the environment settings for that local user. For starting after sign on with RDP. Is this possible anyway? Maybe somebody can put on the right direction.

When I migrated my app, which has worked fine on many machines, to a new one, it didn't run. I would see the hourglass for a second, then nothing.
So I installed VS on that machine and compiled the program.
The debugger does the same thing... just stops. However, sometimes, when it is trying to display a simple message box it gives me:
System.AccessViolationException was unhandled
Message="Attempted to read or write protected memory. This is often an indication that other memory is corrupt."
I have no idea how to deal with this error.
thank you.

There seems to be as many different causes as there are reports of this kind of problem. About the only thing you can do is start going down the list[^] and checking out possibilities.

Are you doing anything with Office in your application? I received the same error message on my development machine after I installed Outlook 2003 and and leaving Office 2002 installed. It turns out this error was caused by different versions of the Office Assistant being installed on the machine. In which case I disabled the office assistant for Office 2002. Don't know if this helps, but just trying to share my experience.

Hi! All,
Can anybody tell me how to check the availability of a database connection in VB?
Thanks and Regards,
virendra

hi virendra,
if you have created the recordset then check for
recordset.state property
if
recordset.state = 1 then connection is open
and if it is '0' then connection is close
best regards,

Hi,
I think you mean <connection object="">.State property.
For eg:-
dim adocn as new ADODB.Connection
Then we can check whether connection is open or not by adocn.State
|
|
|
|
|
What do you mean?
I'm purely guessing at what you want, but about the only way to know is to actually TRY the connection and see if it fails.

Is it possible to set the margins of the windows taskbar like media player 11 does when it is in minimze mode. What i mean is, can we have a form sit over the taskbar and not have the handles for the open or minimized windows flow under it? Is this possible.

I have no idea what you're talking about. When you minimize WMP11, you get the option of turning on a ToolBar that a mini-WMP player occupies.
I have no idea what you're talking about when you say:

This is going to require further explaination.

your right. Sorry that was a bit vague. I've since done some research and found that the thing i need is a deskband application. When WMP11 minimizes to its mini toolbar it is using deskband correct? I tried to find vb.net source code for a deskband but there is virtually none, i think i'm gonna have to take that leap and start the move to C#.

That's what it is.

True. Most examples are going to be in C++, others in C#. it's very much possible to do it in VB.NET though. All it would take is translating the C# code.

Thanks A Lot!!!!!!
Do u have any other link
Its not making clear which method of my code will run in background
Regards

The method you specify, runs in another thread. The events it fires for progress and for the thread ending, occur in your main thread. This is good, you can use these to handle any UI updates.

you can compile .net code on the fly.
There is an article by Jim Rogers here.

There is nothing in the .NET BCL that will do this for you automatically.
Why would need such information anyway?
About the only way I'd see this working is if you put some kind of information logger in every one of your exceptions handlers that called a remote component that logged all of this info. You might want to look into the Exception Handling Application Block[^].

In VB.Net, you can use perfmon.exe utility to get the number of expections.
In VB 6, you would use the errors collection of ADODB connection object and get errors.count
