.net - Keep A Class In A Central Location And Reference It From Multiple Websites?
Aug 19, 2009
We have several VB.NET websites running internal applications. These sites are often modified with minor changes, and are maintained on the server as uncompiled code. I'm looking for the best way to maintain classes so that we can reference them from multiple websites.
Specifically, we're looking to put some common functions (error logging, common database calls, etc.) into a centralized location where they can be maintained separately from the sites and called as needed. And we'd prefer to have this on the server as uncompiled code, so it can be uploaded without precompiling. I feel like I'm missing something obvious, but what is the best way to set this up?

I am wanting to build a menu from multiple xml files in a central location this will be to help with adding crystal reports after application has been deployed to an end user.I am able to get the list of all the xml files in a folder it is just the adding the ReportName to the different menu buttons i have set up.
Dim dirs As String() = Directory.GetFiles(Application.StartupPath & "Reports", "*.xml")
Dim dir As String For Each dir In dirs Dim xe As XElement = XElement.Load(dir)Next

I have an application which writes to and reads from a database. I'd like to be able to have the application installed on a number of computers with the database installed on a central server which all of the applications will connect to.
first of all, installation (installing the app is simple, but how can I get an install program to put the database on the server?), and next, concurrency errors?
I understand that having more than one person trying to update the database at the same time is likely to cause concurrency errors, but short of deploying my application and having everyone try to write to the database at once, I'm not sure how to approach this.

I've got a bunch of DLL projects that I'm pulling into my application, each contains their own Settings.settings/app.config. When I compile the app and run for debugging, everything works just fine, but come deployment time I can't get my DLLs to read their own settings files.I've been doing some reading and it has become apparent that there's a couple of methods to getting each dll to read its own configuration - one is to dedicate a .dll.config to the library and the other is to embed the dll's configuration in the process.exe.config.I'm having significant issues trying to implement either and I wondered if anyone has any good docs on this - there appears to be a shortage on the Net.
I'd like a separate .dll.config for each of the libraries if possible, but in a pinch, getting each of my libraries to read their own section of the process.exe.config will he right direction because I'm so close to rolling this application out but this stumbling block is causing me a significant headache.Edit: When I merge the configuration files, I start getting TypeInitializer exceptions when I initialize objects withing my libraries. This is likely just me being retarded, but does someone have a working example of a merged config file and some basic demonstrative code for reading it from multiple assemblies?

I am a former IT student and have not used VB in a little while but feel it can come in handy to help me complete some tasks at work.I am trying to write a small program which will open a url + a number for each number entered into the textbox. As an example lets say the website is "www.google.com/id=" and I enter into a textbox 3 values such as "134,325,2112", www.google.com/id=134, www.google.com/id=325 and www.google.com/id=2112 would all open at once.
The purpose of this is at work, we have an employee database and would like to load multiple employees at once (upto 6 at a time) to compare profiles. The issue with doing this manually is we have to fill out the search criteria for each, instead, I would like to load a link with parameters in it already filled out + the employee number we are searching for each number entered into a textbox on a VB form.

I have a 'property management class' that contains several functions and properties. I have several other classes that use the 'management class' as a property to derive the value of several of its other properties.Is there a way for me to reference the outer class from the 'management class' functions without having to pass it as a parameter? I ask because several different classes can have this 'management class' as a property and am having a hard time typing the parameter.

If we are within the derived class then ofcource we can use MyBase keyword to access base class's object reference . That's fine , how can we take that base class's object reference outside that derived class's definition.My following code will explain what i want . Actually that is giving error right now, but it is explaining my requirement .
Public Class Base
Public x As String
End Class
[code]....
Actually there is error in ReadOnly Property BaseReference's Getter . Error is "Error 1 'MyBase' must be followed by '.' and an identifier. " how can i get base class object reference in Main method ?

I need to create a new instance of a class that needs a member of the calling class. But i can't pass a reference to the calling class through the constructor.The solution i am looking for is something like this:
Public Class ChildClass
Public Sub New(args)
_MyMember = GetMemberFromCallingClass()
[code]....
I want this to work without having to manually pass any references or variables from the calling class to the new instance of ChildClass.

I have created a class for a Sports Facility. A facility has a Name, Status, Notes, etc as members of the class. This works well, I can create a new instance of an exisitng Sports Facility from the database, create a new instance, etc. All working well.What I am stuck on is accessing a list of Sports Facilities. I know I can create a new list by doing
Dim List As New List(Of Facility)
For Each fRow As DataRow In ds.Tables("Facilities").Rows
List.Add(New Facility(fRow.Item("FacilityID"))

I have this code. credits to jmchiney. My goal is when I press a certain key, the picturebox corresponding to that key should be moved to a certain location. Exactly like in the text twist game.
I have a code running and doing what I want but It is only applicable for single letter. For example the word alabama. all letters without duplicates are placed properly but for letter a, only one letter a is being accepted and moved. that goes for all letters.
Here is the
Dim pb As New PictureBox
Select Case (e.KeyChar)
Case CChar(letterPicbox1.Tag)
[Code].....
Another one. when a certain letter is already placed to the location I set and once I press again the same letter, the location changes. What I want is when I already gave pictureboxA a location and then I press "a" which correspond to pictureboxA again it should be stationary and check if there are other letter "a" in my pictureboxes and move the next detected letter "a" to the next position. Like i said. just like text twist game.

I'm using a central startup routine to initiate several TCP connections, start up a background thread that does some monitoring, and instantiate a group of objects that track information throughout the lifetime of a networking session.
There are periodically server-side problems with the protocol I'm working with, at which point the whole mess has to be torn down and set back up, so at the front end of the startup routine I'm disposing of instantiated tracking objects, killing the monitoring thread, and disconnect/close the existing sockets (if they're already set up). At that point the sockets may be in the middle of an asynchronous send or receive operation, which is causing system exceptions when the socket is torn down and then the asynchronous delegate gets called and EndSend or EndReceive thinks there isn't an object there anymore.
I had assumed .Disconnect and .Close would take care of these async processes, and I'm a little lost. Is there some one-shot method I can use to abort those async operations before I tear the sockets down to re-instantiate them?It never hurts to try. In a worst case scenario, you'll learn from it.

This is the situation: i have the central location with the main computer,and 14 distanced locations connected in VPN and often we need to update program manually (on distanced locations) by overwriting the existing .dll-s of the program and this is pain in the ass to connect remotely to 14 locations and on each workstation overwrite the .dll files so i want to create application which is going to be installed on each WS and by running this app it will check the program folder on central computer and if there is any file with newer version then existing one on the WS it will copy it from central computer and overwrite the old file/s on WS. It is a small app with two buttons and progress bar but the main thing is the Update now button because i dont�t know which commands it should commit.
