I remember seeing a tutorial a while ago about making your application check online for updates..I did this a year or two ago but have since lost my example. Can someone explain how you do this or supply me with a link if you know a good tutorial?
View 20 RepliesOkay so i made a small code that my application can check for updates onstart time. The problem is that it freeze up the application. How can i make it work faster.
Try
My.Computer.FileSystem.DeleteFile(My.Application.Info.DirectoryPath.ToString & "" &
"v.txt")
[code].....
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.
How to do this?Should i use something like sandcastle?

I started working on a big project for like 5 mins ago. Then suddenly I figgerd out that I don't know (AT ALL) how to make a program that can:

- Chat
- Make groups
- Etc

Alright, when I open my program I want it to check for updates and if there is an update I want it to download. So far I have a text file saying the most recent version and then it downloads that file and compares it to the current file version. If the current file version < recent version then it will download the file. :O Can someone help me with the code? :3 I have a hosting server with direct download links.
View 5 RepliesI'm unsure of how realistic it is for this to work but I know a lot is possible in vb. I have an application called WindowsPRO available from my filesharewebsit This application is intended for those in school to easily be able to do several daily tasks such as calculate and use notepad within one window. I have been working on this application in part with the help of MSDN.Back OT, currently when I click the "Check for updates" I use process.start to open my website. Not very complicated is it. What I want to do is open a form in whichchecks for the update from my site. Whenever I upload a file, I'll upload it as a .zip onto my site and always name it like: "Application name v1.0" or whatever the version number is. That is the only thing that changes.
When the user presses the check for updates, I want to checkhe site in background for a "higher" version number. If my application is v1.2, I want it to check for anything higher than 1.2. So if I have on the site 1.2.2, or 1.3, I want it to check for the highest number version and download it.My question simply is, how do I check for a "higher version" from a website?

View 14 RepliesI have a program with commercial uses. Currently I have email out updates. I would prefer that when the program loads, it searches for updates either from the web or I was toying with the idea of creating a file host server. I want the program to search for updates without opening a web browser, however (giving anyone power to email out a free download link). I think of the way Digsby opens, checking for updates, or gimp. This is what I want.

I have created a backup script which my organization uses to back up a specific set of data weekly, to a server, by clicking and running the app.I am always updating it/ improving it and instead of redistributing to the select employees there has to be a way to code in a "check for updates" type of thing.
I was wondering how to make my created app check with that server to see if i am running the latest version.
How do i incorporate a "version" in my app, or would it just be a naming convention thing? and how do i check for updates? Would a button being selected to check updates be preferable? or is there a way to auto detect it?

View 5 RepliesI'm trying to make my app check for updates by reading a text file and comparing it to a 'currentversion' setting in my application (or if checking the executable file version is easy, that would be good).
Here are the basic steps: -Read text file hosted on [URL]..-Check if the version number (eg '1.1') is higher than the number in the 'currentversion' setting or the executable file version (whichever is easier).
-If the text file version number is the same, change form background colour to green, if it is higher, change the background colour to red.
