I don't like Thread.Abort() as it may leave things in an unknown state. I prefer a cooperative way of terminating a thread, which implies the thread code itself checks an exit condition regularly (requiring some code, and causing some exit delay).
I wasn't sure exactly how to terminate the thread, and wasn't sure if I needed to explicitly end it in this case because it just ran through the "z" loop once and exited the sub. In a case like this, is the thread still alive once the sub has finished?

I detest empty catch blocks, I do appreciate you had a comment in there.
If all it does is cope with MakeThms possibly being Nothing, then better test for that explicitly.
I should have explained myself better in the comments. I don't usually leave empty catch blocks. I'm still studying in this area. If I do something like If MakeThms.Equals(Nothing) Then I get a null reference exception.

lvFiles.Invalidate() is forbidden in anything but the main thread. Don't tell me you are either running a very old .NET version (1.x) or have set lvFiles.CheckForIllegalCrossThreadCalls false? For your penitence read this[^].
I'm running .Net 3.5 / VS 2008 Express. I haven't set lvFiles.CheckForIllegalCrossThreadCalls to false. I do get an exception if I use lvFiles.Refresh(). I was pretty sure I shouldn't do this, but amazingly it worked. My primary test directory has 90 images, each 1900x1080 and about 800KB. It takes about 3 seconds to completely rewrite the ImageList. If I quickly select another directory in the TreeView before it's done, it appears to work without any problems. But I was curious since I was touching another thread. I'll dig into the linked article after posting here. Thanks!

1. A thread that runs out of code just terminates; pretty similar to a method that reaches its end and returns.
2. of course If MakeThms.Equals(Nothing) Then is no good, when MakeThms is Nothing, you can't dereference it, so whatever is following the period will cause a bomb. Just do If MakeThms = Nothing Then.
3. Well I am surprised. If that is allowed, then I'll find some use for it indeed. I'll investigate.

I was thinking that was the case. Thanks for confirming it. As I told nbgangsta, sometimes the info at MSDN just bounces off my head instead of soaking in. That's when I end up in the CP forums.

MakeThms = Nothing won't work because "=" isn't supported for threads. If you do investigate Invalidate(), I'd enjoy knowing what you find out. I'm going to try out BackgroundWorker instead of creating my own thread. At first blush it seems less than intuitive to use, but probably safer.

My mistake (and my rusty VB); should be If MakeThms Is Nothing Then (or IsNot). You should have known that, as should I.

I have some code within try...catch blocks that might not always execute properly. One error that might occur is a System.InvalidCastException error. I trap the error, but can I prevent the error from being written to the log?
Thanks
|
|
|
|
|
And who is writing those exceptions to the log? remove the code that does that. Or, much better, do what it takes not to have those casting exceptions in the first place (can't provide detailed help witout seeing the offensive code).

Catch the specific Exceptions first, then the generic Exception:
Try
'some code
Catch System.InvalidCastException
'do something
Catch Exception
'log it and do something
End Try
But of course you should better find the reason for those InvalidCastException, and get rid of them.

Ok so here is my issue.
In all the years that I've been coding I have never come accross this issue or error. For the past 3 months I have been working on two separate apps. Initialy I started out with Win Vista and things were going great except for how slow my comp was running. So I reinstalled the Vista OS. Everything was going great until Mar 7th when this error just started occuring within my code.
"Access to the registry key 'HKEY_CURRENT_USER\Software\TornadoApps\Swift Budget\User' is denied"
"TornadoApps/Swift" Budget are strings created upon App install or first run of App in VB 2008.
The "Use"r value along with 9 other values were all working fine prior to Mar 7th.
Now this line along with many others like it with defferent strings and values were working just fine till this week. So i figured that I'd just upgrade to Win7 hoping that would fix it. IT didn't. So I reformatted and installed fresh Win7 and still have the error. So I have figured out that it isn't my OS. Cuase it was working in Vista then just quit working.
Can anyone help me.

Sometimes you have to manually set these things.
Obviously I cannot tell you the settings for this particular app, but you will need admin rights.
Perhaps re-installing the app may help too, but remove the regentry before reinstalling.

Here's the thing.
On Mon both apps, of my design, were working fine.
Both written in Visual Basic 2008.
One I've been working on since Dec the other just started.
Both access the same reg key, "TornadoApps" and sub keys of "Swift Budget" and "ABO".
Both were working on monday and then for no reason jus stopped workin.
Even after I reformated my comp this error still occures.

Are you using a network login? If so has the network admin down graded the user id so it is no longer a full admin?
A long shot, but have seen something like this in the past (early days of switching to XP).

Go to: Control Panel\User Accounts and Family Safety\User Accounts\User control settings

Free Advice.
Do not use txtspk here.
It is universally loathed, you will not get helped and it makes you look like a child or stupid.
I am sure you are not stupid, so edit you question to reflect this.

Hi Guys
I'm trying to develop a program that is similar to windows explorer. The look and feel of the program is pretty much done.
There is a tree view pane and a list view pane, the tree view pane looks to a local folder (folder2) and displays all folders in that directory. The list view pane shows all files in the corresponding node of the tree view.
The next step is to make the local directory (folder2) pull updated files from a server folder (folder1) as and when there is an updated file put onto the server.
So if a new folder is put on the server in a sub directory for example the program must only copy the updated file over to the local directory.
Here are the basic parameters needed:
1.)I would like this process to happen continuously
2.)It would probably be best to check for an updated file based on date and time modified
3.)I only want the synchronization to happen fron the server to the local pc
I have been told that the microsoft sync framework will be able to do this, but to find a tutorial for VB is like looking for a needle in a haystack.
Please keepin mind that i am seriously new to VB and coding in general!
Is there anything else that i could do to make it clearer or help you guys help me 
Thanks in advance

Here is a Good Article using the FileSystemWatcher. It is in C# but you could use a csharp-to-vb converter.
Hope that helps

Thanks man
I'll take a look...
But is there anybody out there that can point me to a simpler snippet of code, perhaps using a better structure like the sync framework?

Iam using VS2008. Iam developing a application, it contains few forms... But few Forms need certain same calculation, so I can have a Sub or Function...and can call to my required forms....But where to have those Functions...?..
I mean whether we can have a New Form or Class or Interface or Resource File or ..????
Thanks For The Ideas....
