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?

Ive got an app that holds a list of site we have, At each site there are a few devices. The idea is when they click on a site all the details for the site are loaded and then a second thread sits and pings each device to see if its live. Im trying to do this in a seperate thread so if they click another site while its still pinging them it doesn't wait before it switches site. This all seems to be workling fine except if you click through the sites quickly, when you do that it will eventually come up with
Quote:
{"Collection was modified; enumeration operation might not execute."}
The error flags up on the "Next" line in "ThreadedPing"
Thread stuff
Public Sub ThreadedPing(ByVal dt As DataTable)
Try
Dim dr As DataRow

I'm deploying a VB.Net app (VS 2010 Pro) that requiers the user click a command button to open IE to a financial WEB site and download informaion from the site. The app works fine in every detail when installed on the development computer. But, on the target computer when the command button is clicked an unhandled exception occurs which says: System.IO. FileNotFoundException:File Not found.My code behind the button is Shell("C:Program Files (x86)Internet Exploreriexplore.exe www,fidelity.com",AppWinStyle.NormalFocus)
This works fine on the development computer. Do I need a way to code this as a relative path? If so,can you tell me how this is done?Throughout the app I have written relative paths to needed files using paths like (Open(Environment. GEtFolderPath (Environment. SpecialFoldder.Desktop) + "File Name). They all work fine when deployed.

I'm being asked to maintain several internal-only web apps for my company. For testing, after making my changes, I've created some staging sites which make use of separate databases. As such, if my users were to mistakenly use this site as if it were the production site, they may enter important data and wonder where it "disappeared" to thinking it was the production server.
I'd like to create a big banner of some sort across the top of the staging site (which ONLY appears on the staging site) to remind my users that they are on the test site. I'd like recommendations on the best way to do this, with the following considerations:
IDE: Visual Studio 2008
Server: Windows 2003 with IIS 6
Language: VB.NET 2.0

I wish to develop an application in VB.NET to provide to following functionality and hope you can give me some pointers on which direction to take.I need some kind of "server" type component which sits in the background monitoring request from users and performing various task. (this component can be install locally or centrally)
The users submit an instruction to the "server" to perform a certain task at a designated date and time. (or perform the task straight away)
The "server" would perform the task at the desired date and time and inform the user the result of the task.I have thought of using a central database to which the user writes the instructions. The "server" could read from the database to obtain the instructions, and write the result back to the database.
I want a fast reaction to the instructions, so the "server" must poll the database every few seconds; I fear this may be detrimental to performance. Also how do I get the server to perform the task at the desired time? Again checking all outstanding tasks against the current time is not very efficient, so I thought about utilising the Windows Scheduler, but I am not sure of the best way of integrating this functionality.

What is the Best way to create scheduler ?
I can think two ways,
1) to create endless loop that keep checking for time of day, so if i have an event (stored in my DB) that should be execute @ 14:30 the loop will compare in every loop the current time against the DB time so when the current time will be 14:30 the event will be executed
2) the same as above just using Timer instead of endless loop.
the problem is that both methods seems to be inefficient because at least 95% of the checks will be for no use.
so is there any methods or some way in VB.NET to raise an event in a specific hour without keep checking the current hour every second ?

I am trying to write a small program to plan appointments.And have a overview of them in some sort of calendar(not the mini calendar which you can get from the VB control).Found some website who offer such controls, but honestly $1k for the license is a bit to much for something which i am not gonna use that often.So i was wondering if there are any codes available or projects which do something similar.Or any other solution which could work for this.Want to save the data in a SQL database.

I have been working for some time on a service that will act as a task scheduler and perform a shutdown action at one of 3 given shutdown times. Before you cringe and ask why not use the task scheduler, I should explain that permissions do not allow users to "create" scheduled tasks and therefore a creative work-around is required. In any case, I am still new to VB, but am including my code below. I want the service to check an alarm time every minute and launch a shutdown application (in the user's context - if logged in) if that time is NOW.

I have a VB program that is executed each morning at 4 AM by Task Scheduler. If the program returns anything other than a zero result, I would like Task Scheduler to run it again. The Task Scheduler sees my return code in the "Last Run Result" field, but does not invoke the "If task fails, restart every:" action.
