(I've answered the question below with a hack. I'm fairly confident in it unless MS change the way that codedom serializers the designer code.)ETA2:I've worked out what is going on. I wondered why sometimes it would work and not others. It boils down to the name that I give to the internal property and the collection.If I rename the property 'Annoyance' to 'WTF', it will serialize correctly because 'WTF' is, alphabetically, after the name of the collection - 'InternalAnger'.It looks like the serializer is creating instances of objects alphabetically and needs my internal property to be created by the time it comes to create the collection.I can fix this with a rename, but that's a hack and I fear that writing a custom serializer is a big job - which I've never done before.ETA: Jesus, I'm sick of this. This problem was specifically about persisting an interface collection but now on further testing it doesn't work for a normal collection. Here's some even simpler code:
Public Class Anger
End Class
Public Class MyButton

I'm following an article (here) and stuck on the following:"Once you have created this class and compiled it, to use it in an ASP.NET Web application, start by adding it to the Web application's References folder."
Ok, so do i now need to compile my vb class file into a .dll and reference it from the BIN folder? If so how do i compile the vb file? I'm running VS 2005 .net 2.0

So I created an application with vb.net, I added Messenger type Api in preferences, compiled my program and everything was fine. However I can't run the program from other directories. It says that the .dll is missing. I'm trying to include the .dll to the program somehow - no success, how that should be done? Friend tried to help me and said I should add "Application block" something to the references. I can't find that though.

I have this VB ASP.NET Web Service Application project running VS 2005. I'm trying to add references. To do so I click on the "Properties" icon in the Solution Explorer window which presents me with a window to add/update/remove references. I click "Add", I select the reference I want and then "OK". Lo en behold, NOTHING! It simply won't add references (I tried adding several different ones). Specifically I'm trying to add the System.Configuration assembly.

In my VS2010 VB project I have a lot of external references to DLLs, to the point that organization has become a major headache and I'm wondering if I am going about it the wrong way. My assembly references include common redistributables (SQL Server Compact 3.5 SP1, ReportViewer 2010 SP1, DataVisualization, as well as some useful 3rd party dlls from CodeProject and CodePlex.
Currently, I am copying each DLL into a 1st level folder (/dll_lib) under my named project folder (under the solution folder), and adding the reference from that path. However, I see that Visual Studio copies the DLLs to various other locations (/bin/debug or /bin/release) in my project when I build the project or solution, and some of the 3rd party DLLs come with instructions to copy them manually to /bin.
What is the "best practice" for where to put the DLLs? Can I just put all of them under /bin and let the build event copy to /bin/debug or /bin/release as required? Should I try to force a single reference path for the dlls in the project output?

I have an application that is written in VB.NET, using the System.Windows.Forms.Form as the front-end GUI. It runs perfectly on my Windows machine however recently there is a business requirement to convert this application to run as a web application so that people could view them in their blackberries when they go to the URL. Is there any quick way to perform such a conversion or I will have to translate the code line-by-line for such cases?

detect whether the current application is a console or a winforms application.The reason that I want to do this is that I am developing a library with a global error handler in it and I need to know what type of application it is in order to be able to subscribe to the appropriate exception event.Obviously I could get the user to pass in a parameter specifying what type of application it is, but I would rather deal with that automatically so its all encapsulated from the user of the class.

I am developing an .net Winforms application and I need to secure the connection to the sql server 2008 database. I plan to create a webservice as a middle tier that will handle the authentication and that will provide data manipulation. Is there a better way to go with?

I am looking to prompt the user to save data when they close a form window in a winforms application. I can't figure out how to trigger the prompt to the user, should they click the red box at the top right corner of the form.
My application currently has a boolean flag, that is set to True on textchanged event. So I will only need to check for the boolean value in whatever event is trigger by the red box.

My application writes to the event log if there is an error or other status updates.
The application checks to see if there is an event source named "applicationName"and if not, it creates the source (see code below).
This works fine if the user is an administrator.
If the user is not an administrator, an error is thrown when SourceExists is called:
{"The source was not found, but some or all event logs could not be searched. Inaccessible logs: Security."}
In my environment, the typical user is NOT an admin. Therefore, I cannot use the event log in my application.
Is there a way around this, or is the event log effectively useless for distributed applications?

I've a somewhat unusual feature to implement and I don't know if it can be done without much effort.A WinForms application has a help file (well, not HTML help, but simply a HTML file with a reference sheet). When user presses F1 button a form with a web-browser control in it displays showing this file. The client wants this HTML file to contain buttons/checkboxes which a program should respond to.For example, if a user clicks a HTML button in the help file some value should appear in a textbox on the main form, etc. Is it altogether possible

I would like to specify a function to be called in my VB.Net 2005 WinForms project at midnight when the system date changes. Is this possible?I know I could do this by setting a timer by setting the interval to midnight minus the current time, then after the first tick, setting the interval to 24 hours. I was wondering if there was a cleaner, simpler way.

I am working on an application that has a Winforms and MVC3 Web component. We need to be able upload large files from the desktop to the web. I have tried the various VB 2010 WebClient and FTP FileUpload alternatives but continue to run into permission issues, even though the User-ID and password I supply are the same as those used by an FTP application that successfully copies files to the same MVC3 site. In my efforts to find alternative solutions, I have looked into using WCF which also seems complicated and problematic for this particular application.
The closest I have come to a solution utilizes HttpWebRequest on the Winforms application. The following VB 2010 and C# code (MVC3) successfully passes the Filename and File data to MVC3 (the InputStream contains the references and UrlEncode data, but the class containing the fields for this data are null. (I have also passed just the file data without the filename, and the uploaded file is successfully created from the InputStream - but the method variable is still null). Although I could pick apart the InputStream, I would prefer a more elegant alternative.
VB 2010 Winforms method:
Public Shared Sub FileUpload(ByVal Filepath As String)
Try
Dim Host = System.Configuration.ConfigurationManager.AppSettings("Host")
Dim url As String = Path.Combine(Host, "UI/FileUpload")
Dim request As HttpWebRequest = HttpWebRequest.Create(url)
request.Method = "POST"

I am deploying a VB.net 2010 winforms application, and when I install it on the client's machine, the install process also installs an instance of SQL Server 2005 Express. The application connects to a central SQL database on the server. To install, I am using the "Publish" option in VS 2010. Why does it do that? There should be no need for a local instance of SQL Express. Is there a way to avoid installing SQL 2005 Express (I know it is free, but I would rather not have it installed if possible).
