Does An AddHandler Require Parameters
Oct 31, 2011
I'm trying to add a handler, but as soon as I'm targetting a method that has parameters, the handler fails. This is the simple code:
AddHandler App.Current.RootVisual.MouseLeftButtonUp, RootVisual_MouseLeftButtonUp
Private Sub RootVisual_MouseLeftButtonUp(ByVal sender As Object, ByVal e As MouseButtonEventArgs)

I've stumbled upon this code:
var knownSeparators = new[] { "\", "/", "|", "." };
return knownSeparators.FirstOrDefault(path.Contains);
where path is a string and the return value should be a string as well.
Allthough path.Contains' intellisense suggests a parameter, it works fine without one.
How does this work exactly? Is there any way to copy this behavior in vb.net?

I'm writing a query to select all records that has any part of parameter. I have one table called Employees. Some people have name like this: John David Clark If the parameter is
[Code]....
I should be able to get result back as long as there's a match in the parameters. If I use Function Contains (q.FirstName & " " & q.LastName).Contains(employeeName), I will not get any result back if employeeName is "John Clark" Function Contains looks only for next words from left to right. It doesn't match a single word at a time. So that's why I used this in the Linq to SQL:

I have a list of functions that I'm using throughout my .net application. Is there a way that I can include a file into the pages that require the functions without having to copy and paste the functions to each individual page?
The large majority of pages I've found on MSDN are either toward people who are already familiar with .net to those who have never programmed before and just starting. I haven't been able to find one for people who are versed in programming and just need a list of functions and methods.

Never before did i realize the neccessity to scrap the User Account Control, other than for reasons it was simply annoying, until i became a developer. I have an application that does nothing more than remove and create files within its own directory. Are you telling me every application that creates local files require admin rights? Surely something is wrong here. Can this not be circumvented? How do other developers overcome this issue?

If I wrote some software that used an access database to store data. If I then gave the code to a third party, who ran this sofware on his Pc. Would the code work , if his Pc did not have the access database installed.I read in some article that this would still work? If this is true, how could this work? If the above software had an form which required the client to input details of an order. When the order details were being processed by the code where would it store them if no access database was installed on that pc.

My application seems to require .net framework 4 to run. Hence not working on standard XP installations until .net 4 is installed. How do I make it so that it only needs 3.5, or whatever XP uses natively?

For my user system, I require each user to have a unique id. The reading in and saving of the user data is all done, but now I'm focusing on adding new users. In my add user dialog, I have the information fields required to create a new user, one of which is the ID (which must be unique). For this I have created a function that I thought would always give a unique id but it does not. paste the code below:
Function getnextuserid()
Dim id As String
Dim unique As Boolean

Is there any way to use VB 2008 to create an app to work on a computer that does not require .NET 2.0+? If there is no way to install .NET on the target computer, is there any way to write the app in such a way that it works on the computer?

I have an application written in VS2010 that targets FW2.0..It has no dependencies other than the framework.The application runs fine on the local drive.But one user tells me that he already had FW2.0 installed but had to install FW2.0 SP2 in order to get the exe to run if it was placed on a network/shared folder? Why would running from a server/shared folder make the application crash if Sp2 wasn't installed? some network/path error that was was fixed in SP2 that doesn't affect the app when running off the local C drive ?

how I can deploy my .NET applicationwithout the user having to install the program.i.e. In VB6, I could just create a executable file which did not require the user to install anything, they would simple run the program.

I can't figure out why my addhandler is not firing?In the Sub "CreateTagStyle" the AddHandler is not firing when the LinkButton is clicked Is there some reason that addhandlers can't be added at certain points of the page lifecycle?

I came across a snippet of C# code which is very useful. I am trying to convert it to VB.NET, but can't seem to.
timer.Tick += delegate { panel.Children.Add(source); timer.Stop(); };
Is it possible to translate this to something similar in VB?

I'm in a VB.NET application. I have referenced some java.* namespaces in my file and am utilizing objects and methods from this namespace throughout the code. Presumably this is relying upon J# to compile.
Imports java.util
Imports java.util.zip
Imports java.io
Are these JDK namespaces fully contained in the .NET framework, or will my clients need to have Java installed when they go to run my application?As a side note, I have not explicity referenced any external Java DLL's or anything. This is all pure .NET as far as my code is concerned.

I made a little program for Hobby-use, and I like it to be installed by an installer. There's an installer program (Windows Installer 3.1?) deliverd with Visual Studio 2008 but that does not do the job completely. I want a coupling to be made between a program and a the users startup directory.If Windows Installer 3.1 can do that after all, can somebody explain how? If not, is there a free or low cost, simple to use (no scripting) installer program what will do the job? At last: Is there a version of .NET Framework 3.5 that does not require downloading during the user's setup procedure?

I'm not sure that I'm doing the right thing here..I'm writing a user control that's supposed to be (fairly) generic. It's a bit like a modified email client specifically tailored to some of the internal things we do.
The view is composed of two main pieces, a message list and a viewer. I need this viewer to be interchangeable, so if someone wants a different style of view they can simply handle an event and change a property. My original idea was to just have an INoteViewer, but since I'm adding it to my form I also need to guarantee that this object is a Windows.Forms.Control of some sort.
Should I continue along these lines and maybe raise an ArgumentException if I can't cast it to INoteViewer, or should I go a different direction and create a class that inherits from Windows.Forms.Control?

I have placed a few radio buttons in a panel, but I have a weird problem where they require 2 clicks to change their state.If one of the radio buttons is checked, and I click once on another radio button, this will uncheck the checked radio button leaving no radio buttons checked. I then need to click the radio button a second time to change its state to checked.
