I want to check for a system update every .25 seconds. It's very important that it is always .25 seconds apart. I was trying to use do until/while...loop, but it wouldn't let me insert a delay. Does anybody know how to do this/where I could learn to do this?

It checks if the webpage in the web browser control has crashed. The website crashes alot.

The page refreshes every 5 to 120 seconds. The timer gets activated 10 seconds into the program's launch. It refeshes the code above every 5 seconds(to minimize CPU usage). However, it crashes and gives the error "NullReferenceException was unhandled". This could be because the page keeps on refreshing or the page is php and has 2 iframes. How do I fix this?
Quick question - if I have a timer set to 5000 (5 seconds) and the code in the timer takes longer than 5 seconds to run because of sql stuff, will the timer wait until the code is done till it fires again?

View 3 RepliesIs there any way to check from .NET if windows update is enabled?
I want to prompt the users every time they log into my app that their computer might be at risk and give them a link to windows update website (or windows update application from control panel).
Preferably it should work on XP, Vista and Windows 7. Maybe there is a registry key or even better an API?
Supposedly I create a file called "hi.txt" and I use Process.Start(filename) to open it. then I File.Opentext(filename), edit it and close it using stream writer/reader, while I still have that file open.
In order to see the changed text I need to close "hi.txt" and reopen it.
Is there a way to automatically do that? Been experimenting a bit but with no luck.
Is there a way to check if a site had a page update or a new post easily?? Even just to check if something had changed on the page.
View 4 RepliesI'm a beginner to Visual Basic, and I made a simple program, however I want to put a 'check update' button in it... It consists of downloading a txt file that contains three numbers, if it match with the version of the program it says 'you already have the most up-to-date version' or else it asks you to download the update and then bring you to the dev blog of the program I made, however, when I download that file, it brings me a blank txt file instead of the one I uploaded into the site. By the way, I'm downloading it through HTTP.

Since i update my program a lot i want to implement a update system into it And im new to programming, so i would prefer it to be a very simple system.. What i want it to do is, when a user presses a update button it should check on a specific ftp server if the file version is newer than the one the user is having. If it is then it should just download it from the ftp server and then replace the original exe ..
View 7 RepliesWell on my application there is a check for update button and it needs administrative privileges in order for it to download the update (it needs to make a version change in the registry) and I don't have permission to. How can I make it so it asks for permission?
View 2 RepliesI have looked through the entire internet (well that's what it feels like) to find this out.Tables - Authors and Titles add new title must be linked to an author, so I need to check that the author exists, if so, update the titles table with the user data from the textboxes. If the author does not exist, I need to insert the author first & last name into the author table, then the title info into the title table.this is in VB, using ASP.NET, and my database is a file, I'm not using SQL server, just Visual Studio 2008.
Dim insertParameters As New ListDictionary()
insertParameters.Add("ISBN", ISBNTextBox.Text)
insertParameters.Add("Title", titleTextBox.Text)

im slightly new to VB, i was wondering how I make the program check a file for an update, i kknow there is an option in the app settings, but when I go on it it doesnt recognize .vb or .exe files to check from.
If i uploaded updates to a server, how would It check that for updates? and what file type would i need to upload it as?
I found there is something related "OnceClick"[code]...
but how to use it?? Got better solution like tray icon prompt the new version available. then prompt user permission for update~
if user accept to update, it will download from server and install and restart application.
There's an website which lists the manufacturer's of the items they deal with. Upon clicking on the manufacturer link we get the relevant list of items. There are around 60 manuf. and each manuf makes around 500 items.
The complete list of items of an particluar manufacturer is split in pages and displayed on the web page, one page at a time and also links to the next pages.
There are around 4 to 5 items newly added weekly for each manufacturer.
So what i wanted was , first the complete data must be stored in the database and displayed to the user , and later only the updates should be displayed to the user.
For this, what approch i thought is, opening each and every page of the website and then extracting the data form the site and storing in the database. Then again whenever user wants an update , again extacting the complete data from the website and comparing it with the old data and displaying the update.
There are a few threads on these forums about this question, but I need a definite answer.
