My question is, imagine I have two List(Of T) objects and a subroutine in a multithreaded environment that modifies both of these objects. I don't understand locks very well, so I'm unsure whether I can just do:
SyncLock CType(List1, IList).SyncRoot
List1.Clear()
List2.Clear()

Reading a .txt file in VB.net. My file path is C:UsersMyLilMulePepeDocumentsVisual Studio 2008Projectscurtain_calls.txt.
This is my line of Dim LoanOptionsFile As String = "C:UsersMyLilMulePepeDocumentsVisual Studio 2008Projectscurtain_calls.txt"

Context: I'm working with a relatively simple winforms application, written in VB.NET on the .NET 3.5 framework in Visual Studio 2010. Issue: The FormLoad event creates two threads when the program is opened. One handles automatic update checking and the other performs a time consuming task syncing files with the internet. These threads are initialized as follows:

I have one Private sub that runs in a loop. I want the sub to run multiple times at once. For example the program runs, you press start; you run the program again and press start, again and again... the same program doing the job at once. now i just want one program do to it alone. But i would like it to be user defined. exp. run program. type in a text box 10. press start. and it works as if 10 of them work open working on the same thing.

Actually i am making a software which has backend tool as MS ACCESS. it has 15000+ records in database and i need to display that records as my software loads..but it is much time consunable and sometimes it even goes out of time exception
I guess that I'm not the first who ask this, but what is the easiest way to use threads in VB.NET? I mean, I need to download some string from a remote server and then to show that string in the GUI, so I have to use some callback function to call it in the main thread. I found different approaches for this, but all seems very difficult compared to Python where (with GTK) I used something like: gobject.idle_add(callback_function, parameters) and "callback_function" was executed in the main thread. How I do that in VB.NET?

View 1 RepliesI have a webapp where a datagridview is populated with records from a database and one of the columns is a download link to download the zip or exe file. We have the zip files on our server, but not the exe files as those are on another department's server. We have all of the file available for download, but if the user as an option selected in a dropdown, those url's in the gridview are re-formatted to be the exe file's on the other dept's server, however they don't have all of them (some 20% are missing) which means if the user click's the link they get their server's 404 not found page and can't download the file.
My PM (Project Manager) is asking me if I can have our webapp detect that the file doesn't exist on their server and instead of them getting the 404 page, they don't leave our app at all and get a javascript popup window or the page is refreshed with a red mark (and a message) next to the link they clicked on, is something like that possible? I have 2 restrictions with this, I can't modify the database because it doesn't contain file paths, it only contains a small portion like (Clinton County, Eaton County, Traverse County, etc..) and the rest of the url is formatted on the fly when the page is rendered, so there's no way to mark the missing files and there's no way we can host the files.

I got two issues getting my application to download a file. One small and one rather big.The downloader seems to have an issue using the users full download capability while the downloaded size is under 1 MB. As soon as it hits that, it seems to speed up with 10-100 times the previous speed.(Snippet at the end of the post)It seems to have to do with the filesize, which is about 5GB. As soon as my application hits about 1GB it completely locks up. (Without an error message, which I do have built in with a try...catch statement)I actually have to force quit the app to make it stop.It works perfectly fine with a 20MB file.I have the idea it's because of the int64's I use. But I need to use those (afaik) due to the big file size.[code]
