Check For Updates From A Website?
May 4, 2011
I'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?

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.

I don't like to build myprogram to a click-onceapplication becauseI lose the .exe and I don't know how to edit it after building it. So unless someone this, here is my main question:I was thinking about updating a .txt file that have uploaded somewhere that has the current available version. Can I use streamreader for an online file? And if so, if the available version is updated, how can I edit the code and everything to updatethe file?

I 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.

As most programers will want after spending a long time on a program is to implement program updates, so have i.
What i want is a nice simple way of doing the following check if file exists as "www.mydomain.com/program/install.exe" if true, download and launch install.exe on completion, un intstall current vertion ( if possible )

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?

I can get the program to easily, upon startup, look for updates and then install them. I want to have a button that the user can click that will check/install updates.

I'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.

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.

I have an ASP.net 3.5 website and I am using vb.net in VWD 2008 Express, I am also using MS SQL Server 2008 Express, I used ajax tabs and a textBox characters counter control developed by [URL]..The database is attached with MS SQL Server Management Studio Express and the files are stored in the SQL default "Data" folder.
The whole project's code and forms are stored in a folder in my E drive. I need to hand the whole project to another coworker who have to finish it, please describe in steps how can i make my website portable (like i can put it all in a folder that he can carry around in his flash disk).One more thing, I already finished my side of the project, I need to ship it out to this other programmer.
Can anyone suggest something like a: Checklist or Must Do list to achieve this?PS: I have had a problem trying to move the project from one server to the other, the project seems to look for the dlls of the AJAX control and the textBox counter where i originally unzipped the folders in which they cam in, which i think was on my desktop, although when i added those controls to the Tools tab, i created a new tab, then i choose the dll from the where i unzipped the controls source code, aint that enough?

Intended use of program:
1. User enters 1-3 websites they wish to monitor
2. User clicks go next to textbox with data entered, then button and a copy of form refered to as browse is created.
3. Form refered to as browse is directed to the url refered to on the form refered to as monitor, in the associated textbox(passed as a parameter to copyForm)
4. A timer is used to refresh the webpage every 10 seconds
What I wanted to happen was the program turn the associated picturebox in form1 green if page is loaded, and black is loading.

What I want is: To scan a website every 15 mins or so, (craigslist in this case), and email myself any new posts that come up. I know I need to use WebClient, but I never used that before. Another question would be how to only email when a new post is up and not receive the same email every 15 mins.

I have a ASP.NET 2.0 website created in C# that acts as a completely independent site and I am looking to integrate this into an existing ASP.NET 2.0 website created in VB.NET. Unfortunately I just don't know much about the server management side of ASP.NET yet so too much I'm unaware of when it comes to IIS configuration etc. Does anyone have any advice as to how I can go about integrating this? Basically I want to host it in a subdirectory from root so when you hit example.com/myindependantsite/ it will pull up my C# site.
One possible solution I came across mentioned just dropping the project folder into the root directory and setting up that directory as an application virtual directory in IIS? A few other random questions were small things like would my application relative links (~/for-example.aspx) stay relative to my root subdirectory if it's made into an application virtual directory? Just trying to get this running on their site but like I said it's completely independent so want to preserve my websites environment.
